BACKGROUND
[0002] Vehicles such as, but not limited to, motorized scooters, motorcycles, etc.,
among other components and assemblies include body frame, a power unit, a passenger seating area, a storage space, and a set of wheels. The power unit is adapted to provide the necessary power to the wheels, to drive the vehicle. The power unit, seating area, storage space, etc., are all carried by the body frame. The wheels are connected to the body frame. Therefore, the body frame is designed to carry the load of the vehicle, including the weight of the power unit, other components, and sub-assemblies of the vehicle. Such weight carried by the body frame is transferred, through the ground engaging members, to the ground.
[0003] There are situations or needs which require a vehicle to be used as a two
wheeled at one instance and as a three wheeled vehicle at other. However, providing such modular vehicles which may be transformed from a two-wheeled vehicle to a three-wheeled vehicle and vice versa according to need is a difficult and cumbersome task. For instance, conversion of braking systems from two-wheeled configuration to three-wheeled configuration to meet statutory/regulatory requirements of three-wheeled configuration is a cumbersome task. Such conversion is expensive and requires considerable time and modifications.
[0004] The present disclosure is directed to overcome one or more limitations
stated above or any other limitations associated with the conventional vehicles.
SUMMARY

[0005] A modular vehicle is disclosed in accordance with an embodiment of the
present disclosure which is configured to selectively operate in either one of a two-wheeled configuration and/or a multi-wheeled configuration. Said modular vehicle can be easily converted from a two wheeled vehicle to a multi wheeled vehicle, and vice versa, according to the requirements.
[0006] In accordance with an aspect of the present disclosure, a brake actuation
module for the modular vehicle is described. The brake actuation module includes a first master cylinder supported on a primary frame of the vehicle. The first master cylinder is operable when the vehicle is operated in the multi-wheel configuration. The first master cylinder is fluidly connectable to a front brake unit operatively coupled to front ground engaging member. Further, a second master cylinder is supported on a secondary frame attachable to the primary frame of the vehicle. The second master cylinder is fluidly connectable to a rear brake unit operatively coupled to rear ground engaging member. A link is pivotally disposed on a platform between the first master cylinder and the second master cylinder when the vehicle is operated in multi wheeled condition, the link is structured to move between an engaged position and a disengaged position based on actuation of a brake pedal. In the engaged position, the link is configured to actuate the first master cylinder and the second master cylinder to apply brake on the front ground engaging member and the rear ground engaging member concurrently.
[0007] In an embodiment, end faces of the link are configured to abut with the first
master cylinder and the second master cylinder in the disengaged position. The second master cylinder is offset at a distance from the position of the first master cylinder when the vehicle is operated in multi wheeled condition.
[0008] In an embodiment, link is a bell crack lever and is displaceable between a
first position, the disengaged position and the engaged position. In the first position, the link maintains clearance between the primary frame and the secondary frame, the disengaged position in which the substantially flat faces of the link abut against the first and second master cylinder, and an engaged position configured to engage the first and

second master cylinder. Use of bell crank lever enables actuation of the first master cylinder and second mater cylinder concurrently.
[0009] In an embodiment, the brake pedal is displaceable between a first position,
a second position, and a third position. The brake pedal is coupled to the link through a transmitting member, wherein operation of the brake pedal to the third position results in actuation of the transmitting member resulting in movement of the link to the engaged position. Operating the brake pedal to the third position actuates the link to engaged position by pulling the transmitting member. The transmitting member is at least one of a cable and linkage assembly.
[00010] In an embodiment, the brake actuation module comprises a second resilient
member disposed between the link and the platform. The second resilient member is configured to displace the link from engaged position to disengaged position when the brake pedal is released from the third position.
[00011]
[00012] In accordance with another aspect of the present disclosure, a modular
vehicle is described. The modular vehicle includes a primary frame defining the two-wheel configuration. The modular vehicle includes a secondary frame detachably connectable to the primary frame defining a multi-wheel configuration. A front ground engaging member is supported by the primary frame and a pair of rear ground engaging members are operatively coupled to the secondary frame. The modular vehicle further includes a brake actuation module. The assembly includes a first master cylinder supported on a primary frame of the vehicle. The first master cylinder is operable when the vehicle is operated in the multi-wheel configuration. The first master cylinder is fluidly connectable to a front brake unit which is operatively coupled to the front ground engaging member. Further, a second master cylinder is supported on a secondary frame attachable to the primary frame of the vehicle. The second master cylinder is fluidly connectable to a rear brake unit operatively coupled to the pair of rear ground engaging members mounted on the secondary frame. A link is pivotally disposed on the platform

between the first master cylinder and the second master cylinder when the vehicle is operated in the multi-wheel configuration, the link is structured to move between an engaged position and a disengaged position based on actuation of a brake pedal. In the engaged position, the link is configured to actuate the first master cylinder and the second master cylinder to apply brake on the front ground engaging member and the rear ground engaging member. The brake actuation module according to the present disclosure effectively engages the front and rear brake unit of the multi-wheeled vehicle for effective braking. Also, the brake actuation module is relatively simple and has less maintenance. The brake actuation module of the present disclosure is cost effective and can be readily actuated without any modifications based on operational configuration of the vehicle.

[00040] Forthcoming embodiments elucidate a retardation system in the
corresponding figures, only the components necessary for elucidation of the present disclosure may be depicted.
[00041] The modular vehicle (M) described above may require speed deceleration
unit that enable the vehicle to retard or slow down when necessary. As per IS: 14663:2010 and AIS126 regulation, it is mandatory to have a foot pedal operated brakes for three-wheeled vehicle (100b) and for a two wheeled vehicle (100a) it may be either by means of hand lever or foot operated. Hence, in the three-wheeled vehicle (100b) the front brakes (i.e., common for two wheeled and three wheeled configuration) and the rear brakes may have to be operated by means of pedal only. This configuration also enables use of both brakes simultaneously, thus enabling combined braking. The speed deceleration module of the three-wheeled vehicle (100b) may be elucidated hereinafter. The speed deceleration module for the three-wheeled vehicle (100b) enables braking of

wheeled vehicle (100b) three-wheel configuration of the vehicle may be hereinafter explained with respect to FIG.3a, 3b and 4.
[00042] Generally, for a vehicle (100a) of two-wheel configuration, the front ground
engaging member (105) and the rear ground engaging member (103a) may be provided with a speed deceleration module which may be configured to decelerate the vehicle. The speed deceleration module of the two-wheeled vehicle (100a) includes a front brake unit (FB) and a rear brake unit (RB). The front brake unit (FB) may be disposed on the left side of the vehicle along the front end of the vehicle (100a). In some embodiments, the front brake unit (FB) may be disposed on the right side of the vehicle without deviating from the scope of the present disclosure. In some embodiments, the front brake unit (FB) may be disposed on both right and left side of the vehicle. The front brake unit (FB) may be juxtaposed to rim of the front ground engaging member (105) and operatively engaged with the front ground engaging member (105). In an embodiment, the front brake unit (FB) may be at least one of a drum type brake device, disc type brake device or any other brake device known in art, without any limitation. Further, the rear brake unit (RB) of the two-wheeled configuration may be disposed on at least one of the right side or the left side of the vehicle or on both sides on rear portion of the vehicle (100b), without any limitations. In some embodiments, the front brake unit (FB), and the rear brake unit (RB) in the two-wheeled vehicle (100b) may be substantially similar. The front and rear brake units (FB and RB) may be actuated by a brake lever provided on the on the steering mechanism (107). The above-described configuration of the speed deceleration module may be employed in the two-wheel configuration of the vehicle (100a). The speed deceleration module for two-wheeled vehicle (100a) is generally known in art. For the three-wheeled vehicle (100b), it is necessary to employ a braking module for effective braking which may be elucidated henceforth.
[00043] As illustrated the brake actuation module (B) for the modular vehicle (M)
is elucidated. According to present disclosure, it is necessary for the vehicle (100b) in three-wheel configuration to be operated by a brake pedal (P) [refer FIG.3a] as described in earlier embodiments. The brake actuation module (B) for the three-wheeled vehicle

may be accommodated either on the primary frame (102) or the secondary frame (106) or on both. Accordingly, it may be necessary in the three-wheeled vehicle (100b) to operate the front brake unit (FB) and the rear brake unit (RB) simultaneously. Both the front brake unit (FB) and the rear brake unit (RB) must be operated by the brake pedal (P) simultaneously for efficient braking of the vehicle (100b). In an embodiment, various linkage mechanisms may be employed for actuating the front and rear brake units (FB and RB) without deviating from the scope of the present disclosure. One such linkage mechanism for operating the front and rear brake unit (FB and RB) in the three-wheeled vehicle (100b) may be elucidated in the forthcoming embodiments. The brake pedal (P) of the brake actuation module (B) may be pivotally mounted on the body frame of the vehicle. In an embodiment, the brake pedal (P) may be pivotally mounted on cylindrical shaft (CS) fixed to the secondary frame (106). The brake pedal (P) may be defined with a first end (FE) and a second end (SE). The first end (FE) may be structured to receive riders' foot. The second end (SE) of the brake pedal (P) may be operatively fixed to a shaft (S) of the secondary frame (106) and a first resilient member (RM) may be operatively engaged with the brake pedal (P) relative to the shaft (S). A transmitting member (L) may be connected to the second end (SE) of the brake pedal (P). In an embodiment, the transmitting member (L) may be coupled to the shaft (S) [refer FIG.3a] on which the second end (SE) of the brake pedal (P) is mounted. The brake pedal (P) may be configured to be displaceable between three positions i.e., a first position (PI), a second position (P2), and a third position (P3) [three positions of the brake pedal (P) depicted in FIG.3a]. The brake pedal (P) may be in the first position (PI) before the two-wheeled vehicle (100a) is converted to the three-wheeled vehicle (100b). A restraining lever (K) (also referred to as lever (K) and used hereinafter alternatively) [shown in FIG.2b] may be movably secured to the secondary frame (106) abutting the brake pedal (P)... To move the pedal from first position (PI) to the second position (P2), the lever (K) is pressed simultaneously with the brake pedal (P). Simultaneously moving the lever (K) enables movement of the brake pedal (P) to the second position (P2). Once the brake pedal (P) is moved to the second position (P2), the lever (K) is locked relative to the brake pedal (P) ensure that it does not move to its original position, thereby retaining the
hr£iV(=» r^rlal (T*\ m c^crmrl r*r\citir\n ^P9^ TniirfVx^r in rplpucp iht* hr£iV(=» r^rlal (T*\ in iht* firct

position (PI) from second position (P2), the restraining lever (K) is unlocked relative to the brake pedal (P), and the spring force associated with the lever (K)enables the lever (K) along with the pedal (P) to move to first position (PI). Once the brake pedal (P) is in first position (PI), the lever (K) is locked. During the two-wheeled vehicle (100a) into the three-wheeled vehicle (100b), the brake pedal (P) may also subsequently move to the second position (P2) from the first position (PI) of the brake pedal (P) by releasing the lever (K) as described in earlier embodiments. The second position (P2) of the brake pedal (P) may correspond to a disengaged position of the brake pedal (P) [i.e., in this position the brake pedal is moved to operating condition]. Further, the brake pedal (P) may be displaced to the third position (P3) from the second position (P2). Operating the brake pedal (P) to the third position (P3) may actuate the transmitting member (L) to generate braking force. The third position (P3) of the brake pedal (P) may correspond to the engaged position of the brake pedal (P). The transmitting member (L) may be configured to transmit the brake operating force to a first master cylinder (Ml) and a second master cylinder (M2) through a link (10) to decelerate the vehicle. The end of the transmitting member (L) opposite the end connected to the shaft (S) may be coupled to the link (10) disposed proximal to the first master cylinder (Ml) and the second master cylinder (M2). In an embodiment, the transmitting member (L) may be at least one of but not limiting to cable or linkage assembly.
[00044] The first master cylinder (Ml) may be supported on the primary frame (102)
of the vehicle (100b). In an embodiment, the first master cylinder (Ml) may be an auxiliary cylinder which may be operated only in the three-wheeled vehicle (100b). The first master cylinder (Ml) may be disposed on a floorboard (104) of the primary frame (102) of the vehicle (100b). In an embodiment, a platform (108a) may be structured on the floorboard (104) of the primary frame (102). In some embodiments, the platform (108a) may be defined close to the down frame (113). The first master cylinder (Ml) may be supported by the platform (108) defined on the primary frame (102). The first master cylinder (Ml) may be operatively coupled to the front brake unit (FB) provided on the front ground engaging member (105). Similarly, the second master cylinder (M2) may be disposed on the secondary frame (106). The second master cylinder (M2) may be

secured to a platform (108b) [refer FIG.4] defined on the secondary frame (106). The platform (108b) may be offset by a distance from the platform (108a) by a defined distance. The second master cylinder (M2) may be operatively coupled to the rear brake unit (RB) provided for the rear ground engaging member (103b) in the three-wheeled configuration. The functioning of the first master cylinder (Ml) and the second master cylinder (M2) for operating the front and rear brake unit (RB) is well known in the art and is not elucidated herein. The first master cylinder (Ml) and the second master cylinder (M2) may be operated simultaneously by a link (10) which is elucidated further in conjunction to FIG.3.
[00045] The link (10) may be pivotally disposed on a platform (109) that may be
defined on the secondary frame (106). In an embodiment, the platform (109) may be defined at a substantially central portion between the platform (108a) defined on the primary frame (102) and the platform (108b) defined on the secondary frame (106). The platform (109) on the secondary frame (106) may be configured to pivotally accommodate the link (10). In an embodiment, the link (10) may be a bell crank lever but not limiting to the same. In another embodiment, the link (10) may be defined with substantially flat surface (FS) on either end. The substantially flat surface (FS) on either end of the link (10) may be designed to engage with the first master cylinder (Ml) and the second master cylinder (M2), respectively. Further, one end of the link (10) may be coupled to the transmitting member (L). The transmitting member (L) may form a connection between the link (10) and the brake pedal (P). The link (10) of the present disclosure may be displaceable between three positions. The three positions of the link (10) may include a first position (LI), a disengaged position (L2), and an engaged position (L3) [refer FIG.3a]. In the first position (LI), the substantially flat faces (FS) may be parallel to either of the master cylinders (Ml and M2). The first position (LI) of the link (10) ensures that there is enough clearance between the primary frame (102) and the secondary frame (106) during the conversion of the two-wheeled vehicle (100a) to the three-wheeled vehicle (100b). Once the primary frame (102) is connected to the secondary frame (106), with the help of brake pedal (P), the link (10) may be actuated to the disengaged position (L2). In the disengaged position (L2), the substantially flat faces

(FS) of the link (10) may just abut against the first master cylinder (Ml) and the second master cylinder (M2), without actuating the first master cylinder (Ml) and the second master cylinder (M2). Further, the link (10) may be displaced to the engaged position (L3) when the brake pedal (P) is further actuated by the rider to reduce the speed of the vehicle (100b). The engaged position (L3) of the link (10) may be operational position of the link (10) in which the substantially flat faces (FS) of the link (10) are forced against either master cylinders (Ml and M2). Operation of the brake pedal (P) between third position (P3) and second position (P2) results in actuation of the transmitting member (L) which may result in the movement of the link (10) to at least one of engaged position (L3) or disengaged position (L2). Once the brake pedal (P) is released from third position (P3) to the second position (P2), the link (10) may revert to the disengaged position (L2) due to force of the resilient member (110) In the engaged position (L3), end faces of the link (10) may engage with the piston and push the piston of the first master cylinder (Ml) and the second master cylinder (M2) to working condition to engage front and rear brake unit (FB and RB). In the disengaged position (L3), the link (10) may return to normal state due to the force offered by the resilient member (110), thereby releasing the front brake unit (FB) and the rear brake unit (RB).
[00046] Further, a second resilient member (110) may be disposed between the link
(10) and the platform (109). The second resilient member (110) may be disposed at a point of pivot of the link (10). In an embodiment, the second resilient member (110) may be a torsional spring but not limiting to the same. The second resilient member (110) may be configured to displace the link (10) from the engaged position (L3) to the disengaged position (L2), when the brake pedal (P) is released from the third position (P3). The working of the brake actuation module (B) is elucidated in detail in further embodiments.
[00047] When the modular vehicle (M) is to be operated in the three-wheel condition
(100b), the primary frame (102) may be secured to the secondary frame (106) as elucidated in the earlier embodiments of the present disclosure. In the process of securing the primary frame (102) to the secondary frame (106) for conversion of two-wheeled vehicle (100a) to the three-wheeled vehicle (100b), the brake actuation module (B) may also be set-up for operation. As described in earlier embodiments, during the connection

of the two-wheeled vehicle (100a) to the three -wheeled vehicle (100b), the brake pedal (P) may be at the first position (PI) [refer FIG.3]. Similarly, the link (10) will be in the first position (LI) i.e., substantially parallel to either of the primary frame (102) and the secondary frame (106). Once the primary frame (102) is secured to the secondary frame (106), the brake pedal (P) may be moved to the second position (P2). To move the brake pedal (P) to the second position (P2), the lever (K) may be unlocked by releasing the lock pin (LP). The brake pedal (P) and the lever (K) may be simultaneously moved downward, once the brake pedal (P) is moved to second position (P2), the lock pin (LP) is re-slotted, thereby locking the lever (K). The brake pedal (P) may be moved to the second position (P2) may concurrently move the link (10) the disengaged position (L2). In the disengaged position (L2), the substantially flat faces (FS) of the link (10) may abut against the piston of the first and second master cylinder (Ml and M2). The second position (P2) of the brake pedal (P) and the disengaged position (L2) of the link (10) corresponds to disengaged position of the front and rear brake unit (FB and RB). The brake pedal (P) may be further actuated to the third position (P3) which corresponds to the engaged position. Actuating the brake pedal (P) to the third position (P3) concurrently displaces the link (10) to the engaged position (L3), thereby actuating the pistons of the first and second master cylinder (Ml and M2).
[00048] In operation, when the vehicle is configured to be used as the three-wheeled
vehicle (100b) as shown in FIG.2a, the front brake unit (FB) and the rear brake unit (RB) may be operated by the brake pedal (P) for deceleration of the three-wheeled vehicle (100b). The rider of the three-wheeled vehicle (100b) may operate the brake pedal (P) to the third position (P3) to decelerate the three-wheeled vehicle (100b). Once the brake pedal (P) is operated to the third position (P3), the brake operating force on the brake pedal (P) may be transmitted to the link (10) through the transmitting member (L). The transmitting member (L) may be configured to actuate the link (10) to swivel [as shown by arrows in FIG.3] about the point of pivot. When the link (10) swivels about the point of pivot, the faces (FS) of the link (10) on either end form a contact with the first master cylinder (Ml) and the second master cylinder (M2). That is the link (10) swivels to the engaged position (L3) in which the end faces (FS) of the link (10) may engage with the

piston of the first master cylinder (Ml) and the second master cylinder (M2). The link (10) drives the piston to working position to actuate the front and rear brake unit (FB and RB). In the engaged position (L3), the link (10) may be configured to actuate the first master cylinder (Ml) and the second master cylinder (M2) to apply brake on the front ground engaging member (105) and the rear ground engaging member (103b) concurrently. For example, in case the transmitting member (L) is a cable, when the brake pedal (P) is operated to third position (P3), the brake pedal (P) pulls the cable which in turn actuates the link (10) to swivel about the point of pivot to the engaged position (L3). Similarly, when the brake pedal (P) is released, the link (10) returns to the disengaged position (L2). The second resilient member (110) disposed between the platform (109) and the link (10) aids in the link (10) to return back to the disengaged position (L2) which releases the force of front and rear brake unit (FB and RB).
[00049] In an embodiment, the brake actuation module (B) according to the present
disclosure effectively engages the front and rear brake unit (FB and RB) of the three-wheeled vehicle (100b) for effective braking. Also, the brake actuation module (B) is relatively simple and has less maintenance. The brake actuation module (B) of the present disclosure is cost effective and can be readily actuated without any modifications based on operational configuration of the vehicle.
[00050] It is to be understood that a person of ordinary skill in the art may develop
a system of similar configuration without deviating from the scope of the present disclosure. Such modifications and variations may be made without departing from the scope of the present invention. Therefore, it is intended that the present disclosure covers such modifications and variations provided they come within the ambit of the appended claims and their equivalents.
[00051] Equivalents:
[00052] With respect to the use of substantially any plural and/or singular terms
herein, those having skill in the art can translate from the plural to the singular and/or

from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
[00053] It will be understood by those within the art that, in general, terms used
herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system (108) having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances, where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would

understand the convention (e.g., "a system (108) having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B." While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope being indicated by the following claims.
