DESC:INTEGRATED BRAKING SYSTEM FOR VEHICLE

FIELD OF THE INVENTION
[001] The present invention relates to a braking system, and more particularly to an integrated braking system for vehicles such as a two-wheeled vehicle.
BACKGROUND
[002] 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 is normally controlled, by corresponding operator, independently.
[003] For safe braking of the front and the rear wheel 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.
[004] Prior art patent EP0995653A2 discloses an interlock braking system, wherein a master cylinder unit is responsible for the interlock braking. The master cylinder unit has distributing mechanism to distribute input brake load from brake operator into a hydraulic pressure which actuates the front wheel braking device and a mechanical force which actuates the rear wheel braking device. In this system, the master cylinder unit is mounted inside a leg shield at a front portion of the two-wheeled vehicle body.
[005] However, in an integrated braking system where the rear braking device actuates the hydraulic cylinder for front wheel braking, it is not suitable to mount the cylinder in the front portion of the two-wheeled vehicle body, as it will affect the transmission efficiency.

SUMMARY
[006] In an embodiment, an integrated braking system for a two-wheeled vehicle is disclosed. The integrated braking system includes a front brake device (FBD), a rear brake device (RBD), a first brake lever (L1), a second brake lever (L2), an integrated device and a mounting provision. The front brake device (FBD), upon actuation, is configured to apply a brake on a front wheel. The rear brake device (RBD), upon actuation, is configured to apply a brake on a rear wheel.

[0038] An integrated braking system for the vehicle (200), as illustrated in the Figure 4, includes the integrated device (10), the first brake force transmission member (1), the second brake force transmission member (2), the third brake force transmission member (3), the fourth brake force transmission member (4), the first brake lever (L1), the second brake lever (L2), the front brake device (FBD) and the rear brake device (RBD).
[0039] The first brake force transmission member (1) is a conventional brake cable including an inner brake wire (19) and a first outer casing (18), in such a manner that the inner brake wire (19) is movable in relation with the outer casing (18). One end of the inner brake wire (19) of the first brake force transmission member (1) is connected to a rear brake arm (11) of the rear brake device (RBD) and second end of the inner brake wire (19) is connected to the first brake lever (L1).
[0040] The second brake force transmission member (2) is a brake cable including the inner brake wire (19) and a second outer casing (20), in such a manner that the inner brake wire (19) is movable in relation with the outer casing (20). The routing of the second brake force transmission member (2) is not straight and suitably curved. The outer casing (20) of the second brake force transmission member (2) is made stiffer such that it does not deform (try to straighten) till a predetermined force is applied.
[0041] In an embodiment, the third brake force transmission member (3) and the fourth brake force transmission member (4) are hydraulic lines. In an embodiment, the third brake force transmission member (3) and the fourth brake force transmission member (4) are brake cable including the inner brake wire and a second outer casing.
[0042] The integrated braking system includes the integrated device (10), the first brake force transmission member (1), the second brake force transmission member (2), the third brake force transmission member (3), the first brake lever (L1), the front brake device (FBD) and the rear brake device (RBD).
[0043] The integrated device (10) as illustrated in the Figure 5 includes a hydraulic master cylinder (5), an actuator (6) and a bracket (8). In an embodiment, the bracket (8) is realized in the form of casing at least partially enclosing the hydraulic master cylinder (5) and the actuator (6).
[0044] As illustrated in the Figure 5, in an embodiment, the hydraulic master cylinder (5) is mounted on the bracket (8) and has two openings, a first cylinder opening (5a) and a second cylinder opening (5b). The hydraulic master cylinder (5) has a piston actuation end (5c). The first cylinder opening (5a) of the hydraulic master cylinder (5) is fluidically connected to the second brake lever (L2) by the fourth brake force transmission member (4). The second cylinder opening (5b) of the hydraulic master cylinder (5) is fluidically connected to the front brake device (FBD) by the third brake force transmission member (3).
[0045] As illustrated in the Figure 5 and the Figure 6, the actuator (6) is pivotally mounted on the bracket (8) and free to rotate about an axis X1 (e.g., a first axis), wherein the axis X1 is perpendicular to a main surface of the bracket (8) and actuator (6). The actuator (6) has two ends, an actuator first end (6a) and an actuator second end (6b). In an embodiment, the actuator first end (6a) has two flanges as an actuator first flange (f1) and an actuator second flange (f2) (refer Figure 6). Each of the actuator first flange (f1) and the actuator second flange (f2) has one through hole, and these holes have a common axis (X2) which is running parallel to the axis X1. The actuator first flange (f1) and the actuator second flange (f2) can accommodate a pin (7).
[0046] The pin (7) has a through slot substantially perpendicular to the axis X1 and in such a manner that the inner brake wire (19) of the first & second brake force transmission members (1) & (2) can pass through the slot and the outer casing (20) of second brake force transmission member (2) is unable to pass through the slot.
[0047] The bracket (8) has a bracket flange (8a). The bracket flange (8a) allows the inner brake wire (19) of the first brake force transmission member (1) to pass through it and restricts the outer casing (18) of the first brake force transmission member (1).
[0048] When rider actuates the first brake lever (L1), it pulls the inner brake wire (19) of the first brake force transmission member (1) to actuate the brake arm (11) of the rear brake device (RBD) for the rear wheel braking. Because of the reactive forces, subject to initial delays provided in the system, the second brake force transmission member (2) pushes the actuator first end (6a) through the pin (7) in forward direction, and thus the actuator (6) rotates in clockwise direction, as shown in the Figure 5 about the axis X1. The initial delays are due to the stiffness of the outer casing (20) of the second brake force transmission member (2) and friction forces between the inner brake wire (19) and the outer casing (20) of the second force transmission member (2). The piston actuation end (5c) is positioned juxtaposed to the actuator second end (6b) such that the actuator second end (6b) pushes the piston of the hydraulic master cylinder (5) to actuate the front brake device (FBD) for front wheel braking.
[0049] A dust cover (12) is placed in between the bracket flange (8a) and the actuator first end (6a) in such a manner that inner brake wire (19) is passing through the dust cover (12). In an embodiment dust cover acts as a biasing member, which pushes back the actuator first end (6a) from operative position to non-operative position when operator releases the first brake lever (L1).
[0050] The integrated device (10) is mounted in a non-vertical position. The integrated device (10) has the actuator (6) for transmitting the operational force from the second brake force transmission member (2) to the front brake device (FBD) upon actuation of the first brake lever (L1). The second brake force transmission member (2) abuts against the actuator (6) from a rear side and the rear side of the integrated device (10) approaches closer to the rear brake device (RBD) than the front portion of the integrated device (10).
[0051] In an embodiment, the integrated device (10) is placed below a first sub-frame, for example the left sub-frame (117a) of the pair of sub-frames (117a), (117b), in between the front brake device (FBD) and the rear brake device (RBD). In an embodiment, the first sub-frame (117a) is on a same lateral side of the two-wheeled vehicle (200) on which the RBD is positioned.
[0052] In an embodiment, extreme right of the left sub-frame (117a) is on the left side than the extreme right of the integrated device (10), so that the integrated device (10) is protected.
[0053] As per an embodiment of the present invention, the left sub-frame (117a) has a mounting provision (9) (refer Figure 7) extending downward from the left sub-frame (117a). The mounting provision (9) is attached to the left sub-frame (117a) in such a manner that the integrated device (10) can be mounted on the mounting provision (9), below the left sub-frame (117a) in non-vertical position. The bracket (8) of the integrated device (10) is secured to the mounting provision (9) of the vehicle body frame (100) with the help of fasteners.
[0054] Various embodiments of the present invention advantageously provide integrated braking system that ensures reduced length of the second brake force transmission member, which is cost effective and improves the brake force transmission efficiency of the second brake force transmission member. Furthermore, its advantageously designed mounting provision disposed on the vehicle frame body avoids any damages to the integrated device in road accidents, when the vehicle falls down.
[0055] While few embodiments of the present invention have been described above, it is to be understood that the invention is not limited to the above embodiments and modifications may be appropriately made thereto within the spirit and scope of the invention.
[0056] While considerable emphasis has been placed herein on the particular features of this invention, it will be appreciated that various modifications can be made, and that many changes can be made in the preferred embodiments without departing from the principles of the invention. These and other modifications in the nature of the invention or the preferred embodiments will be apparent to those skilled in the art from the disclosure herein, whereby it is to be distinctly understood that the foregoing descriptive matter is to be interpreted merely as illustrative of the invention and not as a limitation.
