The present invention relates to vehicles, for example, two-wheeled vehicles, and more particularly, to brake systems of 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] Conventionally, in two-wheeled vehicles, braking operation of a front wheel is actuated by application of force on a front wheel brake operator provided on a handlebar, and the braking operation of a rear wheel is actuated by application of force on a rear wheel brake operator. The rear wheel brake operator is provided either on the handlebar or provided in form of a foot pedal. The operation of the front and the rear wheel braking was normally controlled, by corresponding operator, independently. [004] For safe braking of the front and rear wheels of the two-wheeled vehicle, the balanced actuation of the front and the rear wheel brakes is necessary. If only the front wheel brake is applied, the rear wheel keeps rolling and the two-wheeled vehicle has risk of being toppled. If only the rear wheel brake is applied, the front wheel keeps rolling and the two-wheeled vehicle has the risk of skidding. To overcome said technical problem, there exists integrated braking systems in which a master cylinder unit is responsible for the interlock braking. The master cylinder unit has distributing mechanism to distribute input brake load from the brake operator into a hydraulic pressure which actuates the front wheel braking device and a mechanical force which actuates the rear wheel braking device.
[005] However, for vehicles having said integrated braking system, at the time of applying parking brake, the rear brake device as well as the front brake device both get actuated with actuation of a parking brake operator. Due to this, pressure is created in the hydraulic lines associated with the front brake device, and prolonged hydraulic pressure created at the front brake device affects durability and life of the front brake system.

The holding pin (114) of the brake lever (110) is disposed within the holding pin casing (116) via a compressed spring (118) such that the holding pin (114) is movable along a height-wise direction of the vehicle (1), when any external force is being applied on the holding pin (114).

[054] In accordance with the present disclosure, to engage the provision (144) of the parking brake lever (140) with the brake lever (110), an intersection of the arms (145, 146) of the parking brake lever (140) that is adjacent the provision (144) of the parking brake lever (140) is passed over the holding pin (114) of the brake lever (110) such that the holding pin (114) is pushed in a downward direction. Consequently, when the provision (144) of the parking brake lever (140) is aligned vertically above the holding pin (114), the compressed spring (118) biases the holding pin (114) away from a bottom surface of the holding pin casing (116), thus positioning the holding pin (114) of the brake lever (110) in the provision (144) of the parking brake lever (140), thereby holding the parking brake lever (140) in the actuated position of the parking brake lever (140), as shown in FIG. 5.
[055] In accordance with the present disclosure, to disengage the parking brake lever (140) from the brake lever (110) or for returning the parking brake lever (140) to the unactuated position, the brake lever (110) is actuated to move towards the actuated position of the brake lever (110), causing the holding pin (114) to come under the intersection of the arms (145, 146) of the parking brake lever (140). Consequently, the torsion spring (142) of the parking brake lever (140) biases the parking brake lever (140) to the unactuated position from the actuated position, as shown in FIG. 6. [056] Further, the brake system (100) of the present disclosure comprises the front actuation cable (180) and the rear actuation cable (190), as shown in FIG. 2. The front actuation cable (180) is a conventional brake cable including a front inner cable (182) enclosed within a front outer sheath (184), in such a manner that the front inner cable (182) is movable in relation with the front outer sheath (184). As shown in FIGS. 2 to 6, the front inner cable (182) is configured to extend between a first end (132) of the brake link (130) and the front wheel brake device (101). Also, the front outer sheath (184) is configured to extend between the brake lever (110) and the front wheel brake device (101). In an embodiment, the front inner cable (182) is configured to extend between the first end (132) of the brake link (130) and a brake arm of the front wheel brake device (101). Also, the front outer sheath (184) is configured to extend between the brake lever (110) and the brake arm of the front wheel brake device (101). Within the scope of the present disclosure, the brake lever (110) is configured to push the front outer sheath (184), upon actuation of the brake lever (110), for actuating the front wheel brake device (101). In particular, when the brake lever (110) pushes the front outer

sheath (184), upon actuation of the brake lever (110), a shape of the front outer sheath (184) changes, thereby causing the front inner cable (182) to move relative to the front outer sheath (184) and thus pulling the front inner cable (182) for actuating the front wheel brake device (101) (or the brake arm of the front wheel brake device (101)) to apply brake on the front wheel (6) of the vehicle (1).
[057] Without deviating from the scope of the present disclosure, the front inner cable (182) of the front actuation cable (180) may comprise a cable clamp (186) attached to an end of the front inner cable (182). The cable clamp (182) may engage with a clamp holder (136) adapted to be disposed on the brake link (130) to couple the front inner cable (182) with the first end (132) of the brake link (130). Similarly, the front outer sheath (184) of the front actuation cable (180) may comprise a cable clamp (188) attached to an end of the front outer sheath (184). The cable clamp (188) may engage with a clamp holder (120) adapted to be disposed in protuberances defined in the brake lever (110) to couple the front outer sheath (184) with the brake lever (110). [058] In accordance with the present disclosure, the rear actuation cable (190) is a conventional brake cable including a rear inner cable (192) enclosed within a rear outer sheath (194), in such a manner that the rear inner cable (192) is movable in relation with the rear outer sheath (194). As shown in FIGS. 2 to 6, the rear inner cable (192) is configured to extend between a second end (134) of the brake link (130) and the rear wheel brake device (102). Also, the rear outer sheath (194) is configured to extend between the parking brake lever (140) and the rear wheel brake device (102). In an embodiment, the rear inner cable (192) is configured to extend between a second end (134) of the brake link (130) and a brake arm of the rear wheel brake device (102). Also, the rear outer sheath (194) is configured to extend between the parking brake lever (140) and the brake arm of the rear wheel brake device (102). Within the scope of the present disclosure, the parking brake lever (140) is configured to push the rear outer sheath (194), upon actuation of the parking brake lever (140), for actuating the rear wheel brake device (102). In particular, when the parking brake lever (140) pushes the rear outer sheath (194), upon actuation of the parking brake lever (140), a shape of the rear outer sheath (194) changes, thereby causing the rear inner cable (192) to move relative to the rear outer sheath (194) and thus pulling the rear inner cable (192) for actuating the rear wheel brake device (102) (or the brake arm of the rear wheel brake device (102)) to apply brake on the rear wheel (19) of the vehicle (1).

[059] Without deviating from the scope of the present disclosure, the rear inner cable (192) of the rear actuation cable (190) may comprise a cable clamp (196) attached to an end of the rear inner cable (192). The cable clamp (196) may engage with a clamp holder (138) adapted to be disposed on the brake link (130) to couple the rear inner cable (192) with the second end (134) of the brake link (130). Similarly, the rear outer sheath (194) of the rear actuation cable (190) may comprise a cable clamp (198) attached to an end of the rear outer sheath (194). The cable clamp (198) may engage with a clamp holder (148) adapted to be disposed in a flanges and/or protuberances defined in the parking brake lever (140) to couple the rear outer sheath (194) with the parking brake lever (140).
[060] In accordance with the present disclosure, to apply brake only on the front wheel (6) of the vehicle (1), the right brake lever (103) may be pressed to subject the right brake lever (103) to the input load. Consequently, the right brake lever (103) may actuate the front wheel brake device (101), via actuation cables, to apply brake to the front wheel (6) of the vehicle (1).
[061] Further, to apply brake to the rear wheel (19) and the front wheel (6) of the vehicle (1), the left brake lever or the brake lever (110) may be actuated from the unactuated position to the actuated position to subject the brake lever (110) to the input load. Consequently, the brake lever (110) and the brake link (130) may pivot, around the first pivot pin (104), to actuate the rear wheel brake device (102) and the front wheel brake device (101), via the rear actuation cable (190) and the front actuation cable (180), respectively, to apply brake to the rear wheel (19) and the front wheel (6) of the vehicle (1). For said braking operation, the brake link (130) distributes the input load between the front wheel brake device (101) and the rear wheel brake device (102). Upon actuation of the brake lever (110), the brake lever (110) and the brake link (130) pivot around the first pivot pin (104). Consequently, the brake lever (110) pushes the front outer sheath (184) of the front actuation cable (180) relative to the front inner cable (182) of the front actuation cable (180), thereby pulling the front inner cable (182) for actuating the front wheel brake device (101) to apply brake on the front wheel (6) of the vehicle (1). Also, the brake link (130) pulls the rear inner cable (192) of the rear actuation cable (190) relative to the rear outer sheath (194) of the rear actuation cable (190), thereby actuating the rear wheel brake device (102) to apply brake on the rear wheel (19) of the vehicle (1).

[062] As per an embodiment of the present disclosure, an operation and actuation of parking brake, via the parking brake lever (140), may be understood as: [063] When it is desired to park the vehicle (1), the parking brake lever (140) may be actuated from the unactuated position to the actuated position by pivoting the parking brake lever (140) around the second pivot pin (106). Consequently, the parking brake lever (140) pushes the rear outer sheath (194) of the rear actuation cable (190) relative to the rear inner cable (192) of the rear actuation cable (190), thereby pulling the rear inner cable (192) for actuating the rear wheel brake device (102) to apply brake on the rear wheel (19) of the vehicle (1).
[064] It can thus be contemplated that actuation of the parking brake lever (140), from the unactuated position to the actuated position, facilitates applying brake only on the rear wheel (19) of the vehicle (1), and thus parking brake actuation on the rear wheel (19) is provided without pressure generation in the front wheel brake device (101), thereby not affecting life and durability of the front wheel brake device (101). [065] Within the scope of the present disclosure, the braking system (100) of the present disclosure facilitates applying brake only via the rear wheel brake device (102) when the parking brake lever (140) is actuated, and thus parking brake actuation on the rear wheel (19) is provided without pressure generation in the front wheel brake device (101), thereby not affecting life and durability of the front wheel brake device (101). Also, the braking system (100) of the present disclosure provides easy and convenient distribution of the input load between the front wheel brake device (101) and the rear wheel brake device (102). Further, the provision of the parking brake lever (140) facilitates securely holding the parking brake lever (140) in the actuated position and not allow return of the parking brake lever (140) to its original unactuated position until required. Also, the torsion spring (142) provides returning the parking brake lever (140) to the unactuated position when the parking brake lever (140) is released from the holding pin (114).
