Present disclosure generally relates to a field of vehicles. Particularly, but not exclusively, the present disclosure relates to a combined braking system for vehicles.
BACKGROUND
[002] The information in this section merely provides background information related to the present disclosure and may not constitute prior art(s) for the present disclosure.
[003] In existing two wheeler vehicles, braking operation of front wheel is actuated by application of force on a front wheel brake actuating means provided on the handle bar. The braking operation of a rear wheel is actuated by application of force on rear wheel brake actuating means. Rear wheel brake actuating means is provided either on a handlebar or on a foot pedal. The operation of the front and rear wheel braking is normally controlled, by the operator, independently and sometimes simultaneously.
[004] In order to provide safety to the rider and the passenger a balanced and simultaneous actuation of braking on the front and rear wheel of the vehicle is required. If only the front wheel brake is applied, the rear wheel keeps rolling forward to push the vehicle body such that the vehicle has the risk of being toppled over. If only rear wheel brake is applied, the front wheel keeps rolling forward to push the vehicle body such that the vehicle has the risk of sliding and causing unsecured steering movement. And, if both the front and rear wheel brakes are applied simultaneously, both the front and rear gets stopped immediately but the inertia of vehicle causes the rider to move forward leading to uncomfortable ride or may create the danger of possible injury.
[005] Vehicle manufacturers have sought, proposed, and implemented different ways in which a combined braking on the front wheel and the rear wheel of the vehicle can be achieved. Now-a-days, the vehicles are mounted with a combined braking system in which a front wheel brake and a rear wheel brake are operated in a combined manner, when the rider of the vehicle either operates a brake pedal provided on foot pedal or a brake lever provided on the handlebar. The combined braking system allows stopping of the vehicle by actuating both the front wheel brake and the rear wheel brake.

[006] However, there are some problems associated with the combined braking system of the vehicle, preferably two-wheelers, said problems are for example -implementation of complex links connected with one another and directly or indirectly connected with the brake pedal of the vehicle. The implementation of such links utilize more packaging space of the vehicle and hinder mounting of other peripheral components of the vehicle. The braking effectiveness of combined braking system could not be achieved due to complex mounting structure and implementation of plurality of force distribution links. The existing combined braking system are expensive as they utilize more number of components and thereby, increases the overall cost of the vehicle, for example - manufacturing cost, maintenance cost, service cost and likewise.
[007] The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the existing combined braking systems of vehicles.

The brake rod (42) is configured to transmit actuating forces to the rear wheel brake unit (41) from the second link (12) upon actuation of the brake pedal (10) of the system (100). The intermediate portion (12b) is defined as a portion between the first arm (12a) and the second arm (12c). In an exemplary embodiment, the intermediate portion (12b) is having a cylindrical structure defined with a center through hole to facilitate mounting of the second link (12) on to the frame (20) of the vehicle (200). The second arm (12c) extends from the intermediate portion (12b) forming a predefined angle "a" in a fourth quadrant of a cartesian plane. The angle a is defined as an angle formed between a vertical axis Y-Y passing through center of the intermediate portion (12b) and an axis Z-Z passing through center of the second arm (12c) of the second link (12), as shown in Figure 6. The second arm (12c) comprises a flange (12d) mounted on frontward

surface of the second arm (12c). The flange (12d) is aligned parallel to the second arm (12c) of the second link (12).
[064] Referring to Figures 8a-8d, an assembling of the components and/or sub-components of the combined braking system (100) is depicted. The second link (12) is first inserted in a hollow mounting member, preferably a hollow rod of the frame (20) of the vehicle (200) and then the first end (10a) of the brake pedal (10) is inserted in the same mounting member. The brake pedal (10) with the first link (11) having a unitary structure gets aligned with the second link (12), such that a surface of the first end (10a) of the brake pedal (10) coincides with a surface of the intermediate portion (12b) of the second link (12). Alternatively, the center of the first end (10a) and the center of the intermediate portion (12b) lies on the pivotal axis X-X, as shown in Figure 8a. Once, the brake pedal (10) and the second link (12) are inserted in the mounting member, a rod (21) is inserted inside the hollow mounting member of the frame (20), to facilitate locking of the brake pedal (10) and the second link (12) with the mounting member. The rod (21) prevents an axial movement of the brake pedal (10) and the second link (12) along the pivotal axis X-X.
[065] Referring to Figure 2 and Figure 8b, the brake cable (32) comprises an inner wire (32a) and an outer sheath (32b). The inner wire (32a) of the brake cable (32) is connected to the first link (11). The outer sheath (32b) of the brake cable (32) abuts to the second arm (12c) of the second link (12), such that the first link (11) actuates the front wheel brake unit (31) and the second link (12) actuates the rear wheel brake unit (41), upon actuation of the brake pedal (10). The inner wire (32a), preferably made from a plurality high tension metal wires, is allowed to pass through an intermediate member (32c) and the outer sheath (32b) abuts against an inner surface of the intermediate member (32c). The intermediate member (32c) may be defined as a grommet preferably made from a composite material having elasticity. The intermediate member (32c) is then placed between the flange (12d) and the second arm (12c) of the second link (12). The intermediate member (32c) is connected to the second link (12) by means of a locking cap (32d), as shown in Figure 8b. The locking cap (32d) is first received in a hole provided on the flange (12d) and then in a hole provided on the second arm (12c) of the second link (12), to lock or connect the intermediate member (32c) with the second link (12).

[066] Referring to Figure 8c, a first clip (33) is attached to a first end of the inner wire (32a) of the brake cable (32). The first clip (33) is configured to connect the inner wire (32a) with the first link (11). The first clip (33) is defined having a U-shaped structure having one hole on each side wall of the first clip (33), such that each hole is aligned with a hole provided on the first link (11). The first clip (33) attached to the inner wire (32a) is locked with the first link (11) by means of a first fastener (34). The first fastener (34) may be defined as a bolt to facilitate locking of the first clip (33) with the first link (11) of the system (100). The other end of the brake cable (32) is connected to the front wheel brake unit (31) mounted on the at least one front wheel (30) of the vehicle (200). The front wheel brake unit (31) is operatively connected the combined braking system (100) by the brake cable (32), such that the inner wire (32a) of the brake cable (32) is connected with the first link (11) and the outer sheath (32b) abuts with the second arm (12c) of second link (12) to avoid bending of the brake cable (32) and thereby improves the brake effectiveness.
[067] The first arm (12a) of the second link (12) is connected to the rear wheel brake unit (41) by the brake rod (42). The brake rod (42) is defined as a solid metallic rod made from any material, preferably iron, or other metal alloys. The brake rod (42) comprises a second clip (43) attached at one end of the brake rod (42). The second clip
(43) is defined having a U-shaped structure having one hole on each side wall of the second clip (43), such that each hole is aligned with a hole provided on the first arm (12a) of the second link (12). The second clip (43) attached with the brake rod (42), is connected to the first arm (12a) by means of a second fastener (44). The second fastener
(44) may be defined as a bolt to facilitate locking of the second clip (43) with the first arm (12a) of the second link (12). Referring to Figure 8d, one end of the spring (13) is then mounted on the first pin (13a) of the first link (11) and other end of the spring (13) is then mounted on the second pin (13b) of the second arm (12c) of the second link (12). The other end of the brake rod (42) is connected to the rear wheel brake unit (41) mounted on the at least one rear wheel (40) of the vehicle (200).
[068] Referring to Figures 9a-9e, different positions of the brake pedal (10) during actuation of the combined braking system (100) is depicted. Figure 9a shows the first position (may be referred as "initial position") of the brake pedal (10) and other sub-components of the system (100). The first position is defined as a position in which no

force is exerted on the brake pedal (10) and no wheel brake unit (31, 41) is actuated thereby. The first position of the system (100) may also be referred to as the position of brake pedal (10) during non-working condition of the system (100). Figure 9b shows, a second position of the brake pedal (10) and the first arm (12a) of the second link (12). The second position of the brake pedal (10) is achieved when the operator or rider exerts force at the second end (10b) of the brake pedal (10), to facilitate pivotal movement of the brake pedal (10) about the first end (10a) in clock-wise direction. In second position, the pivotal movement of the brake pedal (10) facilitates pivotal movement of the first link (11), which in turn exerts pulling force on the second arm (12c) of the second link (12). The pulling force exerted on the second arm (12c) facilitate pivotal movement of the second link (12) in a clock-wise direction, exerting a pulling force on the brake rod (42) and resulting in application of the rear wheel brake unit (41) thereby. During application of push force on the brake pedal (10), the rear wheel brake unit (41) is actuated first and resulting application of braking force on the rear wheel (40) of the vehicle (200). If the operator or rider continues to exert more force on the brake pedal (10), then the first link (11) integrally formed with the brake pedal (10) pulls the inner wire (32a) of the brake cable (32) to actuate the front wheel brake unit (31) and simultaneously the rear wheel brake unit (41) is already in the actuated condition.
[069] The position of the brake pedal (10) under this circumstance is defined as a third position, as shown in Figure 9c. In the third position, the actuation of front wheel brake unit (31) takes place by pulling of the inner wire (32a) of the brake cable (32). Referring to Figure 9d, a fourth position of the brake pedal (10) is depicted. The fourth position may also be referred to as an extreme position or an actuated position of the brake pedal (10). The fourth position of the brake pedal (10) is achieved if the operator continues to exert an extra force on the brake pedal (10) to stop the vehicle (200) within a short distance. In the actuated position, the pivotal movement of the brake pedal (10) results in pivotal movement of the first link (11) and at the same time the second stopper (10c) abuts with the second arm (12c) of the second link (12). The abutting action of the second stopper (10c) with the second link (12) facilitates synchronized pivotal movement of the brake pedal (10) with the pivotal movement of the second link (12). Also, the abutting action of the second stopper (10c) prevents extra actuation of the front wheel brake unit (31) mounted on the front wheel (30) of the vehicle (200). This

action prevents toppling of the operator or rider during driving the vehicle (200) and thereby prevents accidents during driving.
[070] In an exemplary embodiment of the present disclosure, the actuation of the rear wheel brake unit (41) is disclosed, during non-working condition of the front wheel brake unit (31). The non-working condition of the front wheel brake unit (31) may be defined as a condition when the inner wire (32a) of the brake cable (32) connecting the front wheel brake unit (31) with the system (100) is broken or gets removed while driving the vehicle (200). Referring to Figure 9e, the actuated position of the brake pedal (10) is shown, and the first link (11) is not connected to the front wheel brake unit (31) by the brake cable (32). When an operator exerts push force on the brake pedal (10), the brake pedal (10) pivots about the axis X-X passing through the first end (10a). The pivotal movement of the brake pedal (10) facilitates abutting of the second stopper (10c) with the second arm (12c) of the second link (12). The abutting action of the second stopper (10c) exerts a push force on the second arm (12c), resulting in pivotal movement of the second arm (12c) and thereby pivotal movement of the second link (12) in clockwise direction. The pivotal movement of the second link (12) applies pulling force on the brake rod (42), which in turn actuates the rear wheel brake unit (41). Alternatively, the second stopper (10c) is configured transmit pivotal movement to the second link (12) during non-working condition of the front wheel brake unit (31). The actuation of the rear wheel brake unit (41) facilitates stopping of the vehicle (200) in a predefined location even when the brake cable (32) of the front wheel brake unit (31) is not connected with the brake pedal (10).
[071] In an exemplary embodiment, a method for actuation of a combined braking system (100) of a vehicle (200) is disclosed. The method comprises: pivoting a brake pedal (10) for movement of a first link (11) about a pivot axis X-X, to exert a pulling force on a second arm (12c) of a second link (12) and to initiate pivotal movement of the second link (12) about the pivot axis X-X, such that the brake pedal (10), the first link (11) and the second link (12) pivots about the pivot axis X-X. Now, actuating the rear wheel brake unit (41) by pivotal movement of the second link (12) and simultaneously actuating the front wheel brake unit (31) by pivotal movement of the first link (11), to provide a combined braking effect on the vehicle (200).

[072] In an embodiment of the present disclosure, the combined braking system provides an effective combined braking on both the front wheel and the rear wheel of the vehicle. The front wheel brake unit is operatively connected the combined braking system by the brake cable, such that the inner wire of the brake cable is connected with the first link and the outer sheath abuts with the second arm of second link to avoid bending of the brake cable and thereby improves the brake effectiveness.
[073] In an embodiment of the present disclosure, the combined braking system has less number of components and/or sub-components and thereby reduces the overall cost of the vehicle.
[074] In an embodiment of the present disclosure, The combined braking system comprises a single distribution link (second link, in accordance with the present disclosure) on the brake pedal and a common pivot axis for the distribution link and the brake pedal provides a simple system, which is easy to service/maintenance and easy to assemble.
[075] In an embodiment of the present disclosure, The combine braking system is mounted in one plane which eliminates any lateral force/moments on joints and hence utilizes the pedal force to the maximum level.
