The present disclosure relates to vehicles. Particularly, but not exclusively,
the present disclosure relates to a clutch actuation mechanism for a vehicle. Embodiments of the present disclosure discloses a clutch adjuster for the clutch actuation mechanism for the vehicle.
BACKGROUND
[0002] Typically, a clutch assembly is provided between a prime mover, such as an
engine or a motor, of a vehicle and a transmission system of the vehicle to provide a smooth shift between gears and to facilitate transfer of power from the prime mover to the transmission system. The clutch assembly generally includes clutch plates, a clutch release pin, a clutch shaft, and clutch springs. The clutch assembly can be actuated by a clutch actuation assembly, for example, a cable clutch actuation assembly or a hydraulic clutch actuation assembly and the like.
[0003] The cable clutch actuation assembly includes a clutch lever and
a clutch cable. When a rider or driver of the vehicle manually imparts a force on the clutch lever, the clutch cable gets drawn or pulled. The clutch cable actuates the clutch assembly by separating the clutch plates from each other, which results in disengagement of the clutch assembly. Accordingly, when the rider releases the clutch lever, the clutch springs bring the clutch plates back to their normal position, thereby re-engaging the clutch assembly. In the engaged state, the clutch assembly facilitates the transfer of power from the prime mover to the transmission system whereas, in the disengaged state, the clutch assembly enables shifting of gears. Due to frequent operation of the clutch to engage and disengage the clutch assembly components such as clutch plates undergoes wear resulting and cable may expand due to tension resulting slack in the clutch which has to be adjusted for proper and continued functioning of the clutch assembly. Conventionally, slack adjusters are provided close to the engine which would pose challenges for riders to access and adjust the slack in the clutch cable.

[0004] The present disclosure is directed to overcome one or more limitations
stated above or any other limitations associated with the conventional vehicles.

[00029] The vehicle embodying the clutch actuation mechanism (100) of the present
disclosure is depicted in the corresponding FIG.l, a brief description of the vehicle (15) is provided in forthcoming embodiments. The vehicle (15) referred to herein embodies a motorcycle. Alternatively, the vehicle may embody any other ridden vehicles such as scooters, three-wheeled vehicle, modular vehicle, all-terrain vehicle etc. without limiting to the scope of the present disclosure. The vehicle (15) includes a frame (10), a steering assembly (101), a front ground engaging member (12). The frame (10) supports the steering assembly (101), and the front ground engaging member (12) in front portion of the vehicle (15). The front ground engaging member (12) is operatively connected to the steering assembly (101). The steering assembly (101) includes a handlebar (101a). Further, front portion of the vehicle (15) may include headlight assembly (16), front fork (13), front fenders (17), dash assembly [not shown], mirrors (18), indicator lights (19) etc. without limiting to the scope of the invention.
[00030] The vehicle (15) further includes a power unit (114) [in the instant
disclosure referred to as an engine] [as shown in FIG.la], and a rear ground engaging member (14). In the illustrated example, the power unit (114) may provide necessary power required to drive the rear ground engaging member (14) of the vehicle (15). Alternatively, the power unit (114) may provide necessary power to drive the front ground engaging member (12), or both the front ground engaging member (12) and the rear ground engaging member (14) simultaneously, without limiting to the scope of the disclosure. The frame supports the power unit (114) in a substantially middle portion of the vehicle (15). The power unit (114) may comprise engine and a transmission unit. The engine (114) generates the power required by the vehicle (15). The transmission unit transmits the generated power to the rear ground engaging member (14). The engine (114) may be configured to drive the transmission unit through a plurality of gears accommodated in a gearbox (not shown). The gearbox is a mechanical device used to increase the output torque or to change speed of the engine (114). An output shaft of the

engine (114) is connected to one end of the gearbox through the internal configuration of gears of the gearbox. The output shaft is also referred to as a clutch shaft that may be configured to transfer power from the engine (114) to supply to transmission unit. The clutch shaft or driving shaft may be connected through a clutch and when the clutch is engaged, the driving shaft through the plurality of gears may rotate the transmission shaft of the transmission unit. The clutch is configured to engage and disengage power from the engine (114) to the transmission unit. In one configuration, the clutch is a series of spring-loaded plates that, when pressed together, connect the transmission unit to the engine shaft. When the rider of the vehicle (15) intends to shift gears, the clutch is disengaged with the aid of a clutch actuation mechanism (100). The rider may disengage the clutch by operating the clutch cable (109) (as shown in FIG.la). The clutch cable (109) may be structured to connect a lever arm (112) (as shown in FIG. la) and a clutch lever (103). In an embodiment, the lever arm (112) may be provided over the power unit (EU) particularly engine cover (113). The lever arm (112) may be coupled to the clutch which may be provided within the power unit (EU). The clutch lever (103) may be pivotally connectable to the handlebar (101a) through a lever bracket (103a) (as shown in FIG. lb). The clutch actuation mechanism (100) configured to engage and disengage the clutch is elucidated in the forthcoming embodiments.
[00031] Referring to FIG(s) lb to 4 in conjunction, the clutch actuation mechanism
(100) and the features of the clutch actuation mechanism (100) is depicted. As described in the above embodiments, the clutch actuation mechanism (100) [hereinafter referred to as mechanism (100) and alternatively used] includes among other components the clutch lever (103) [refer FIG.2], actuation assembly (not shown) and the clutch cable (109). The clutch lever (103) may be pivotally connectable to the handlebar (101a) through a lever bracket (103a) [refer FIG.2]. One end of the clutch cable (109) may be connectable to the clutch lever (103) and another end opposite to the one end of the clutch cable (109) is connectable to the lever arm (112) provided on the engine cover (113). The lever arm (LA) may be operatively coupled to the clutch lever (103). To shift gears, the rider of the retracts the clutch lever (103) towards the handlebar (101a). The retraction of the clutch lever (103) actuates the clutch assembly that includes the clutch cable (109) having an

inner wire (109a) and a clutch cable housing (107). Operating the clutch lever (103) to the retracted position towards the handlebar (101a) pulls/draws the clutch cable (109) in the direction of the clutch lever (103). The clutch cable (103) in turn pulls the lever arm (112), thus transferring the motion of the clutch lever (103) to the lever arm (112). Actuating the lever arm (112) further actuates the clutch assembly [not shown]. The clutch assembly includes clutch plates, a pair of springs, a clutch actuating member, a clutch bearing for supporting the clutch actuating member etc. The clutch actuating member is pushed to separate the clutch plates in the clutch assembly, thereby ensuring disengagement of the clutch assembly. As the clutch assembly is in disengaged state, the rider can make the required shift in the gears. Once the required gear is engaged, the rider releases the clutch lever, thus releasing tension in the clutch cable. Accordingly, the clutch cable (103) and in turn the lever arm (112) are released, thereby returning to normal condition. This releases pressure on the clutch assembly and brings the clutch plates together thereby reengaging the clutch assembly. With prolonged usage i.e., the process of retraction and releasing the clutch cable (109) creates slack in the clutch cable (109). The slack in the clutch cable (109) should be adjusted for proper actuation of the clutch. The clutch adjuster (102) may be provided in the clutch actuation mechanism (100) for adjusting the slack in the clutch cable (109). The clutch adjuster (102) will be elucidated in the forthcoming embodiments. The clutch adjuster (102) is depicted in FIG(s) 2 to 4.
[00032] The clutch adjuster (102) for adjusting slack in the clutch cable (109)
includes a first adjuster (106). The first adjuster (106) may be defined with a first end (115) and a second end (116) [refer FIG.4]. In an embodiment, the first adjuster (106) may be an elongated cylindrical member defining a hexagonal shape on an outer circumference. The first adjuster (106) may be defined with a channel. The first adjuster (106) is a female connector configured to receive external components which will be elucidated in forthcoming embodiments. In an embodiment, the second end (116) of the first adjuster (106) may be defined with an opening to receive an external component. Further, the first end (115) of the first adjuster (106) is configured to receive a portion of the cable housing (107) of the clutch cable (109). The first end (115) may be crimped to

abut against the cable housing (107). In an embodiment, the cable housing (107) may include an end cap (111) [refer FIG.2 and 3]. The end cap (111) ensures that the cable housing (107) resides within the first adjuster (106). The end cap (111) along with the crimped portion of the first adjuster (106) on the cable housing (107) ensures that movement of the cable housing (107) is restricted within the first adjuster (106). Further, the second end (116) of the first adjuster (106) may be defined with threads in an inner surface.
[00033] Further, the clutch adjuster (102) includes a second adjuster (104). The
second adjuster (104) may be receivable by the first adjuster (106). The second adjuster (104) is a male connector configured to be inserted into the first adjuster (106). The second end (116) of the first adjuster (106) may be dimensioned to receive the second adjuster (104). In an embodiment, the second adjuster (104) may be threadably engaged with the second end (116) of the first adjuster (106). The second adjuster (104) may be defined with a first section (104a) and a second section (104b) as shown in FIG.4. Further, a collar (110) may be defined between the first section (104a) and the second section (104b). The first section (104a) of the second adjuster (104) may be defined with threads on an outer surface. The first section (104a) may be threadably receivable by the first adjuster (106) from the second end (116). The second adjuster (104) and the first adjuster (106) may be configured to move relative to each other. Further, the second section (104b) of the second adjuster (104) is structured to abut against the lever bracket (103a) [refer FIG.2]. In an embodiment, a provision may be provided in the lever bracket (103a) to receive the second section (104b) of the second adjuster (104). In another embodiment, the second section (104b) may be threadingly engaged with the provision defined in the lever bracket (103a). The first adjuster (106) and the second adjuster (104) may be structured to receive and route an inner wire (109a) of the clutch cable (109). The first adjuster (106) and the second adjuster (104) may be adapted to displace relative to each other to adjust slack in the clutch cable (109). That is the first adjuster (106) may be moved in at least one of a first direction (FD) or a second direction (SD) relative to the second adjuster (104) to adjust the slack in the clutch cable (109). In an embodiment, a lock nut (105) [shown in FIG.4] may be disposed between the first adjuster (106) and the

second adjuster (104) [as shown in FIG.2 and 3]. The lock nut (105) may be threadingly engaged with the first section (104a) of the second adjuster (104). Further, the lock nut (104a) may be configured to be tightened against a face of the first adjuster (106) to arrest relative displacement between the first adjuster (106) and the second adjuster (104).
[00034] Forthcoming embodiments illustrate the assembly procedure for the clutch
cable (109) and the clutch adjuster (102). Although a particular way of assembling the clutch cable (109) to the clutch adjuster (102) is elucidated, the same should not be taken as a limitation of the present disclosure. The clutch cable (109) comprising the inner wire (109a) and the cable housing (107) may be selected. In an embodiment, either ends of the inner wire (109a) may be defined with a barrel (108) [as shown in FIG.4]. The clutch cable (109) may then be defined with the clutch adjuster (102). In an embodiment, one end of the clutch cable (109) may be provided with said clutch adjuster (102). Initially, the first adjuster (106) is connected to the portion of the cable housing (107) such that the fist end (FE) of the first adjuster (106) abuts against the cable housing (107). The portion of the cable housing (107) which extends into the first adjuster (106) through first end (115) may be provided with the end cap (111) [as shown in FIG.3b]. The end cap (111) may be crimped on to the portion of the cable housing (107) extending into the first adjuster (106). The end cap (111) ensures that the movement of the cable housing (107) is arrested within the first adjuster (106). Once, the clutch cable (109) is connected to the first adjuster (106), the inner wire (109a) of the clutch cable (109) is routed through the first adjuster (106) into the second adjuster (104). Further, the first section (104a) of the first adjuster (104) is threadably engaged with the first adjuster (106) [as shown in FIG(s) 3a and 3b]. Before coupling the second adjuster (104) to the first adjuster (106), the lock nut (105) is disposed between the first and second adjuster (106 and 104). The lock nut (105) as described in the earlier embodiments is threadably engaged with the first section (104a) of the second adjuster (104). Coupling the first adjuster (106) and second adjuster (104) along with lock nut (110) to the clutch cable (109) defines the clutch adjuster (102)
[00035] Further, the inner wire (109a) routed through the first and second adjuster
(106 and 104) is coupled to the clutch lever (103) and the end of the inner wire (109a) opposite to the end connected to the clutch lever (103) is connected to the lever arm (112).

In an embodiment, the second section (104b) of the second adjuster (104) may be ingressed into the provision defined in the lever bracket (103a). In other words, the second section (104b) of the second adjuster (104) may be accommodated in the provision defined in the lever bracket (103a) and the collar (110) may rest against the surface of the lever bracket (103a). In operation, when there is a small amount of slack in the clutch cable (109), the second adjuster (104) resting against the lever bracket (103a) may be adjusted. Turning the second adjuster (104) out of the provision defined in the lever bracket (103a) ensures reducing of the slack in the clutch cable (109) and vice-versa. However, in case of higher slack in the clutch cable (109), the first adjuster
(106) may be moved relative to the second adjuster (104). Moving the first adjuster (106)
relative to the second adjuster (104) towards the lever bracket (103a) increases the slack.
Similarly, moving the first adjuster (106) relative to the second adjuster (104) and away
from the lever bracket (103a) decreases that slack in the clutch cable (103a).
[00036] In an embodiment, the clutch adjuster (102) provided in the clutch actuation
mechanism (100) is easy to access when compared to conventional adjusters. In conventional system, the adjuster nut is provided on the engine, which poses accessibility issues. In the mechanism (100) of the present disclosure, the clutch adjuster (102) is provided close to the handlebar (101a) which can be easily accessed by the rider. The clutch adjuster (102) is directly ingressed into the lever bracket (103a) which guides the clutch cable (109) without bend near the handlebar (101a), thus increasing the efficiency of clutch cable (109). The structure of the clutch adjuster (102) ensures that cable housing
(107) does not undergo bending stress, thereby avoiding cracks on the cable housing
(107). The clutch adjuster (102) according to the present disclosure is cost effective as
minimal number of parts are used.
[00037] It is to be understood that a person of ordinary skill in the art may develop
a mechanism 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.

[00038] Equivalents:
[00039] 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.
[00040] 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 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.).
