Specification

Present disclosure relates to a field of automobiles. Particularly, but not exclusively, the present disclosure relates to a brake system of a vehicle. Embodiments of the present disclosure disclose an integrated brake system of the vehicle.
BACKGROUND
[2] Integrated brake systems are type of brake systems in which a front brake is actuated when a front brake lever is operated, while both the front and rear brakes are applied when a rear brake lever is operated. Generally, integrated brake systems are known to include a front disc brake and a rear drum brake. Conventionally, in the existing integrated brake systems, two master cylinders are adapted. Adapting two master cylinders may escalate cost and maintenance of the integrated brake system, which is undesired. Further, in some integrated brake systems, one master cylinder is used, which is mounted on one end of the handle bar and at other end, a brake distribution unit is positioned. Such configuration demands for design changes, which are complex and may lead to poor aesthetics of the vehicle, particularly handle bar area, which is again undesired.
[3] The present disclosure is directed to overcome one or more limitations stated above
SUMMARY
[4] The one or more shortcomings of the prior art are overcome by an integrated brake system of a vehicle as claimed, and additional advantages are provided through the provision of the system/method as claimed in the present disclosure. Additional features and advantages are realized through the techniques of the present disclosure. Other embodiments and aspects of the disclosure are described in detail herein and are considered a part of the claimed disclosure.
[5] In accordance with an aspect of the present disclosure, an integrated brake system of a vehicle is disclosed. The integrated brake system includes a front wheel brake device configured to apply brake to a front wheel of the vehicle, and a rear wheel brake device

configured to apply brake to a rear wheel of the vehicle. Further, the integrated brake system includes a front brake lever adapted to be pivotally coupled at one end of a handle bar of the vehicle and a rear brake lever adapted to be pivotally coupled at other end of the handle bar of the vehicle. Furthermore, the integrated brake system includes an integrated device disposed on a frame body of the vehicle. The integrate device includes a master cylinder, an actuating lever and an arm. The actuating lever is adapted to pivot upon actuation of the front brake lever and thereby actuate the master cylinder. Additionally, the integrated brake system includes a front actuation cable which includes an outer hose and a front inner cable movably disposed within the outer hose. The front inner cable at one end is operatively connected to the front brake lever and at other end is connected to the lever. Upon actuation of the front brake lever, the front inner cable displaces to pivot the lever to actuate the master cylinder. Further, the integrated brake system includes a front brake hose, fluidly connected to the master cylinder and the front wheel brake device. The front hose is configured to actuate the front wheel brake device, upon pivotal movement of the actuating lever. Furthermore, the integrated brake system includes a rear actuation cable. The rear actuation cable includes a first outer casing provided between the rear brake lever and the integrated device, a second outer casing provided between the arm and the rear wheel brake device and a rear inner cable movable in relation to the first outer casing and the second outer casing. The rear inner cable is configured to operatively couple the rear brake lever at one end and the rear wheel brake device, at other end. Upon actuation of the rear brake lever, the rear inner cable is adapted to actuate the rear wheel brake device for applying brake to the rear wheel, and the second outer casing is adapted to push the arm, as a result of reactive forces generated upon actuation of the rear brake lever, for actuating the master cylinder and applying brake to the front wheel of the vehicle.

[7] In an embodiment, the actuating lever is configured to pivot about an axis A-A and the arm is configured to pivot about an axis B-B. Pivotal movement of the actuating lever and the arm aids in selective actuation of the master cylinder, relative to actuation of the front brake lever and the rear brake lever, for applying brake to the front wheel.

[8] In an embodiment, the integrated device comprises a first bracket to which the lever is pivotally connected and a protrusion extending from the first bracket. The protrusion is configured to support an end of the outer hose. Further, the integrated device includes a second bracket to which the arm is pivotally connected and a projection extending from the second bracket.

[9] In an embodiment, the integrated brake system includes a supporting member disposed on a top portion of the master cylinder. The supporting member is defined with a stepped portion on either side to receive an end of the actuating lever and an end of the arm. The supporting member is configured to actuate the master cylinder corresponding to pivotal movement of at least one of the actuating lever and the arm. That is, the supporting member helps each of the actuating lever and the arm to independently actuate the master cylinder relative to actuation of the front brake lever and the rear brake lever, respectively.
[10] In an embodiment, the integrated brake system includes a first resilient member extending between the protrusion and other end of the lever. The first resilient member is configured to assist pivotal movement of the lever upon actuation of the front brake lever. In other words the first resilient member provides biasing force to the actuating lever for smooth pivotal movement, relative to actuation and de-actuation of the front brake lever. Further, the integrated brake system includes a second resilient member extending between the projection and other end of the arm. The second resilient member configured to assist pivotal movement of the arm upon actuation of the rear brake lever.
[11] In an embodiment, integrated brake system includes a reservoir, which is fluidly communicated with the master cylinder and configured to store brake fluid. The reservoir is positioned outside a boot frame of the vehicle such that, the reservoir is visible to the operator for monitoring brake fluid level in the reservoir.

[12] In an embodiment, the front brake hose is configured to channelize pressurized brake fluid to the front braking device for braking the front wheel of the vehicle, corresponding to pivotal movement of the actuating lever, relative to actuation of the front brake lever.
[13] In accordance with another aspect of the present disclosure, a two-wheeled vehicle is disclosed. The two-wheeled vehicle includes a steering mechanism, a head pipe configured to rotatably support the steering mechanism and a frame body extending from a front end to a rider' s seat of the vehicle along a longitudinal length. The frame body is supported by a front ground engaging member and rear ground engaging member. The front ground engaging member is supported by a plurality of front forks connected to the head pipe of the vehicle and the rear ground engaging member is supported by the swing arm and a rear suspension device connected to the pair of seat rails. Further, the two-wheeled vehicle includes an integrated brake system. The integrated brake system includes a front wheel brake device configured to apply brake to a front wheel of the vehicle, and a rear wheel brake device configured to apply brake to a rear wheel of the vehicle. Further, the integrated brake system includes a front brake lever adapted to be pivotally coupled at one end of a handle bar of the vehicle and a rear brake lever adapted to be pivotally coupled at other end of the handle bar of the vehicle. Furthermore, the integrated brake system includes an integrated device disposed on a frame body of the vehicle. The integrate device includes a master cylinder, an actuating lever and an arm. The actuating lever is adapted to pivot upon actuation of the front brake lever and thereby actuate the master cylinder. Additionally, the integrated brake system includes a front actuation cable which includes an outer hose and a front inner cable movably disposed within the outer hose. The front inner cable at one end is operatively connected to the front brake lever and at other end is connected to the lever. Upon actuation of the front brake lever, the front inner cable displaces to pivot the lever to actuate the master cylinder. Further, the integrated brake system includes a front brake hose, fluidly connected to the master cylinder and the front wheel brake device. The front hose is configured to actuate the front wheel brake device, upon pivotal movement of the actuating lever. Furthermore, the integrated brake system includes a rear actuation cable. The rear actuation cable includes a first outer casing

provided between the rear brake lever and the integrated device, a second outer casing provided between the arm and the rear wheel brake device and a rear inner cable movable in relation to the first outer casing and the second outer casing. The rear inner cable is configured to operatively couple the rear brake lever at one end and the rear wheel brake device, at other end. Upon actuation of the rear brake lever, the rear inner cable is adapted to actuate the rear wheel brake device for applying brake to the rear wheel, and the second outer casing is adapted to push the arm, as a result of reactive forces generated upon actuation of the rear brake lever, for actuating the master cylinder and applying brake to the front wheel of the vehicle.
[14] The configuration of the integrated brake system of the present disclosure facilitates in using one master cylinder, thus making the integrated brake system simple and cost effective. Further, the configuration eliminates the need of brake distribution unit and the master cylinder from being mounted on the handle bar. This results in obtaining flexibility in the handle bar design and effective braking. Further, by eliminating the mounting of the master cylinder on the handle bar, reactive forces from the second outer casing of the rear actuation cable can be utilized to actuate the front brake device, since multiple bends of the actuation cable is mitigated, which would require for routing the actuation cable till the handle bar. Furthermore, the configuration aids in reducing length of the hydraulic hose, which reduces cost of the brake system.
[15] It is to be understood that the aspects and embodiments of the disclosure described above may be used in any combination with each other. Several of the aspects and embodiments may be combined together to form a further embodiment of the disclosure.

The taillight and a rear fender are provided at a rear portion of the side frame cover. The vehicle (200) may include a stand (not shown) provided under the vehicle frame body (201). Additionally, the vehicle (200) includes an integrated brake system (100), which will be elucidated in the forthcoming embodiments. The integrated brake system (100) may be disposed on a frame body (201) of the vehicle (200) and may be adapted for braking the vehicle to either slow down or halt the vehicle.
[30] The above disclosure provided is for better understanding of the present disclosure. Hereinafter, the integrated brake system (100) is elucidated. In the corresponding figures, only the components necessary for elucidation of the present disclosure may be depicted.

[31] Reference will now be made to the exemplary embodiments of the disclosure, as illustrated in the accompanying drawings. Wherever possible, same numerals have been used to refer to the same or like parts. The following paragraphs describe the present disclosure with reference to Figures 3 to 5.
[32] Figure 3 illustrates a perspective view of the integrated brake system (100) [hereinafter referred as brake system]. The brake system (100) may include a front wheel brake device (101) which may be configured to apply brake to the front wheel (102). Further, the brake system (100) may include a rear wheel brake device (103), which may be configured to apply brake to the rear wheel (104) of the vehicle (200). In an illustrated embodiment, the front wheel brake device (101) is a disk brake and the rear wheel brake device (103) is a drum brake. However, the same cannot be construed as a limitation since the front wheel brake device (101) and the rear wheel brake device (103) may be one of the disc brake and the drum brake, based on requirement. As apparent from Figure 3, the brake system (100) may include a front brake lever (105) adapted to be pivotally coupled to an end of the handle bar (206) [best seen in Figure 2]. The front brake lever (105) may be adapted to be actuable by an operator to selectively actuate the front wheel brake device (101) for applying brake to the front wheel (102). Further, the brake device may include a rear brake lever (107) adapted to be pivotally coupled to other end of the handle bar (206) [best seen in Figure 2]. The rear brake lever (107) may be adapted to be actuable by an operator to selectively actuate both the rear wheel brake device (103) and the front wheel brake device (101) for applying brakes to the rear wheel (104) and the front wheel (102), respectively.
[33] Referring now to Figures 3 to 5, the brake system (100) may include an integrated device (108), which may be disposed on the frame body (201) of the vehicle (200). In an embodiment, as best seen in Figure 2, the integrated device (108) may be disposed on the head pipe (202) of the vehicle (200). The integrated device (108) may include a master cylinder (109) which may be fluidly coupled to a reservoir (140). The reservoir (140) may be configured to store brake fluid and may be positioned outside a luggage boot frame of the vehicle (200) such that, the reservoir (140) is visible to the operator for monitoring the brake fluid level in the reservoir (140). As best seen in Figures 3 and 5, the integrated

device (108) may include an actuating lever (110) which may be pivotally disposed adjacent to the master cylinder (109), with one end of the actuating lever (110) contacting a top portion of the master cylinder (109). The actuating lever (110) may be configured to selectively actuate the master cylinder (109) corresponding to its pivotal movement. Further, the integrated device (108) may include an arm (113) which may be pivotally disposed adjacent to the master cylinder (109), with one end (114) of the arm (113) contacting the top portion of the master cylinder (109). The arm (113) may be configured to selectively actuate the master cylinder (109) corresponding to its pivotal movement. In an embodiment, the actuating lever (110) and the arm (113) may be disposed at either sides of the master cylinder (109) and opposite to each other.
[34] In an embodiment, the integrated device (108) may include a support member, which may be disposed on the top portion of the master cylinder (109) [thus, a top portion of a piston in the master cylinder (109)]. The support member may be defined with a stepped portion on either sides which may confirm to a substantially L-shaped configuration. The stepped portion on either sides of the support member may be configured to receive the one end (111) of the actuating lever (110) and the one end (114) of the arm (113). The support member may facilitate independent actuation of the master cylinder (109) by the actuating lever (110) and the pivotal movement of the arm (113), corresponding to their pivotal movements. In other words, the pivotal movement of one of the actuating lever (110) and the arm (113) exerts force on to the top portion of the master cylinder (109) [thus, the piston of the master cylinder (109)]. The exerted force may cause the piston to displace inside the master cylinder (109), thereby pressurizing the brake fluid, which may then be channelized to the front wheel brake device (101) for applying brake to the front wheel (102).
[35] Referring further to Figure 5 the integrated device (108) may include a first bracket (132) and a protrusion (133) extending away from the first bracket (132). The first bracket (132) may be removably coupled to the master cylinder (109) or the frame body (201), and the protrusion (133) may be removably coupled to the first bracket (132) or may integrally extend from the first bracket (132). The protrusion (133) may confirm to a substantially L-shaped configuration and may be defined with an opening (134). In an embodiment, the

first bracket (132) may be configured to pivotally support the actuating lever (110) such that, the actuating lever (110) may pivot about an axis A-A, upon actuation of the front brake lever (105). Further, the integrated device (108) may further include a second bracket (135) and a projection (136) extending from the second bracket (135). The projection (136) may resemble substantially L-shape and defined with a provision (137). The second bracket (135) may be removably coupled to the master cylinder (109) or the frame body (201) and the projection (136) may be removably coupled to the second bracket (135) or may integrally extend from the second bracket (135). The second bracket (135) may be configured to pivotally support the arm (113) such that, the arm (113) may pivot about an axis B-B, upon actuation of the rear brake lever (107).
[36] Now referring to Figures 3 and 4, the brake system (100) may further include a front actuation cable (116). The front actuation cable (116) may extend between the front brake lever (105) and the actuating lever (110). In an embodiment, the front actuation cable (116) may include an outer hose (117) and a front inner cable [not shown in Figures] enclosed within the outer hose (117). One end (118) of the outer hose (117) may be statically connected to the front brake lever (105) and an other end (119), opposite to the one end (118) may be statically connected to the protrusion (133) via the opening (134). As an example the other end (119) of the outer hose (117) may be statically connected to the protrusion (133) (thus, the opening (134) of the protrusion (133)) through but not limiting to a fastener. Further, one end of the front inner cable may be operatively coupled to the front brake lever (105) and the other end, opposite to the one end may be operatively coupled to an other end of the actuating lever (110). As seen in Figure 4, the brake system (100) may further include a front brake hose, which may be fluidly connected to the master cylinder (109) and the front wheel brake device (101). Corresponding to actuation [i.e., pressing] of the front brake lever (105), the front inner cable displaces [i.e., pulled towards in a direction of pressing of the front brake lever (105)], causing the actuating lever (110) to pivot about axis A-A, thereby actuating the master cylinder (109). Actuating the master cylinder (109) causes the pressurized fluid to channelize through the front brake hose, thereby actuating the front wheel (102) brake, for braking the front wheel (102).

[37] Referring further to Figures 3 to 5, the brake system (100) may include a rear actuation cable (124). The rear actuation cable (124) may include a first outer casing (125) and a second outer casing (128). In an embodiment, the first outer casing (125) and the second outer casing (128) may spaced apart from each other. Further, the rear actuation cable (124) may include an rear inner cable [not shown in Figures] disposed within the first outer casing (125) and the second outer casing (128) and configured to move in relation to the first outer casing (125) and the second outer casing (128). One end of the rear inner cable may be operatively coupled to the rear brake lever (107) and an other end, opposite to the one end may be operatively coupled to the rear wheel brake device (103). Further, one end (126) of the first outer casing (125) may be statically coupled the rear brake lever (107) and an other end (127), opposite to the one end (126) may be statically coupled to the projection (136) via the provision (137). As an example, the other end (127) of the first outer casing (125) may be statically connected to the projection (136) [thus, the provision (137) of the projection (136)] through but not limiting to a fastener. Furthermore, one end (129) of the second outer casing (128) may be operatively connected to other end (115) of the arm (113). As an example the one end (129) of the second outer casing (128) may be operatively connected to the other end (115) of the arm (113) through but not limiting to a fastener, snap fit and the like. In an embodiment, the other end (115) of the arm (113) may be defined with a cavity in which the one end (129) of the second outer casing (128) may be received, where the one end (129) of the second outer casing (128) may be snappily secured in the cavity or may be secured through a fastener. Further, the other end (130), opposite to the one end (129) of the second outer casing (128) may be operatively coupled to the rear wheel brake device (103). Corresponding to actuation [i.e., pressing] of the rear brake lever (107), the rear inner cable may displace [i.e., pulled in a direction of pressing of the rear brake lever (107)]. This displacement of the rear inner cable may actuate the rear wheel brake device (103) for braking the rear wheel (104). Further, as a result of the braking the rear wheel (104), reactive forces may be generated due to which the second outer casing (128) displaces in the direction pulling of the rear inner cable. This displacement of the second outer casing (128) may cause the arm (113) to pivot, leading to actuation of the master cylinder (109). The master cylinder (109) upon actuation may channelize the pressurized brake fluid through a front hose (121), for

actuating the front wheel (102) device, for braking the front wheel (102). Thus, actuation of the rear brake lever (107) causes actuation of both the rear wheel (104) brake and the front wheel brake device (101).
[38] Referring again to Figures 3 and 4, in an embodiment, the integrated device (108) may include a first resilient member (138), which may be configured to extend between the protrusion (133) and the other end (112) of the actuating lever (110). That is, ends of the first resilient member (138) may be connected to the protrusion (133) and the other end (112) of the actuating lever (110). The first resilient member (138) may be configured to provide biasing force during pivotal movement of the actuating lever (110), to facilitate smooth pivotal movement of the actuating lever (110) corresponding to actuation and de-actuation of the front brake lever (105). Further, the integrated device (108) may include a second resilient member (139), which may be configured to extend between the projection (136) and the other end (115) of the arm (113). The second resilient member (139) may be configured to provide biasing force during pivotal movement of the arm (113), for smooth pivotal movement of the actuating lever (110) corresponding to actuation and de-actuation of the rear brake lever (107).
[39] In an operational embodiment, that is, during braking, upon actuation [i.e., pressing] of the front brake lever (105), the front inner cable displaces [i.e., pulled towards a direction of pressing of the front brake lever (105)], causing the actuating lever (110) to pivot for actuating the master cylinder (109). Actuating the master cylinder (109) causes the pressurized fluid to channelize through front brake hose for actuating the front wheel brake device (101) to apply brakes to the front wheel (102). Further, upon actuation [i.e., pressing] of the rear brake lever (107), the rear inner cable may displace [i.e., pulled in a direction of pressing of the rear brake lever (107)] for actuating the rear wheel brake device (103) to brake the rear wheel (104). As a result of braking the rear wheel (104), reactive forces may be generated due to which the second outer casing (128) may displaces in the direction of displacement of the rear inner cable. This displacement of the second outer casing (128) may cause the arm (113) to pivot, causing actuation of the master cylinder (109). The master cylinder (109) upon actuation, may channelize the pressurized brake fluid through the front hose (121), for actuating the front wheel (102) brake, thereby

braking the front wheel (102). Thus, actuation of the rear brake lever (107) causes actuation of both the rear wheel (104) brake and the front wheel (102) brake for braking both the rear wheel (104) and the front wheel (102), respectively.
[40] The configuration of the integrated brake system (100) of the present disclosure facilitates in using one master cylinder, thus making the integrated brake system (100) simple and cost effective. Further, the configuration eliminates the need of brake distribution unit and the master cylinder from being mounted on the handle bar (206). This results in obtaining flexibility in the handle bar (206) design and effective braking. Further, by eliminating the mounting of the master cylinder on the handle bar (206), reactive forces from the second outer casing (128) of the rear actuation cable (124) can be utilized to actuate the front brake device (101), since multiple bends of the rear actuation cable (124) is mitigated, which would require for routing the actuation cable till the handle bar (206). Furthermore, the configuration aids in reducing length of the hydraulic hose, which reduces cost of the brake system (100).
