BRAKING SYSTEM
FIELD OF THE INVENTION
[0001] The present invention relates to a combined braking system of a motorized
vehicle.
BACKGROUND
[0002] Conventionally, in two wheeled vehicles, braking operation of a front wheel
is actuated by application of force on a front wheel brake actuating means provided on a
handlebar, and braking operation of a rear wheel is actuated by application of force on a
rear wheel brake actuating means. The rear wheel brake actuating means is typically
provided either on the handlebar or on a foot pedal of the two wheeled vehicle. The
operation of the front and the rear wheel braking is normally controlled, by the operator,
independently and sometimes simultaneously.
[0003] For safe braking of the front and the 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 forward so as to push the vehicle
body, and the two wheeled vehicle may have a risk of being toppled over. Further, if only
the 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.
Moreover, if both the front and the rear wheel brakes are applied simultaneously, both the
front and rear wheels get stopped immediately, but the inertia of the two wheeled vehicle
may cause the rider to move forward leading to uncomfortable ride or may create the
danger of a possible injury.
SUMMARY

First Embodiment
[0033] In the first embodiment as depicted in Figure 1, a braking system (1 00) in a
vehicle comprises inter-alia, a front wheel braking device (1 08) such as a disc brake for
operating brake on a first wheel (116) (e.g., a front wheel), a rear wheel braking device
(1 09) such as a drum brake for operating brake on a second wheel (118) (e.g., a rear
wheel), a first brake actuating means (1 02) such as a brake lever mounted on the
handlebar of the vehicle, and a second brake actuating means (103) such as a brake pedal.
The braking system ( 1 00) also comprises a link member ( 1 05) rotatably inounted on the
vehicle body frame, and is provided with a biasing spring ( 11 0) which keeps the link
member (1 05) biased to a default position of the link member (1 05). Further, the braking
system (1 00) comprises a first connecting means (1 07) in the form of a cable, where the
first connecting means ( 1 07) is employed to connect the first brake actuating means ( 1 02)
to the link member (1 05). Furthermore, the braking system ( 1 00) comprises a second
connecting means such as a front wheel connecting means ( 1 06F) and a rear wheel
connecting means ( 1 06R).
[0034] In this embodiment, the front wheel connecting means (1 06F) is a hydraulic
system provided with a master cylinder, and the rear wheel connecting means (1 06R) is a
mechanical system. The second brake actuating means (103) includes a sub-link (113),
wherein the sub-link (113) moves forward upon actuation of the second brake actuating
means (103). The rear wheel braking device (109) can be actuated by pulling a metallic
rod (111), where the metallic rod (111) at one end _is connected to the sub-link (113). The
sub-link (113) is further connected to the link member (1 05) by a wire rope ( 112).
12
IPO DELHI 02-·99-2015 11:12
[0035] When the second brake actuatin·g means (I 03) is operated to be rotated
clockwise as indicated by arrow (B) in Figure I, the sub-link ( 113) moves forward pulling
the metallic rod (Ill) in the forward direction, thereby causing the actuation of the rear
wheel braking device (I 09) only.
(0036] When the first brake actuating means (I 02) is operated to be moved towards
the handlebar grip, the first connecting mt!ans (1 07) is pulled causing the link member
(1 05) to swing clockwise as depicted by arrow (A) in the Figure 1. The clockwise
swinging of the link member (105) is adapted to actuate a piston of the master cylinder
thereby a hydraulic pressure is generated which renders the front wheel braking device
(1 08) operative. Furthermore, the clockwise swinging movement of the link member
(1 05) upon actuation of the first brake actuating means ( 1 02), simultaneously or with a
pre-determined delay, causes the sub-link (113) of the second brake actuating means
(103) to move forward. The forward movement of the sub-link (113) pulls the metallic
rod (111) in the forward direction causing actuation of the rear wheel braking device
(1 09). Thus, actuation of the first brake actuating means (1 02) causes the front wheel
braking device ( 1 08) and the rear wheel braking device (1 09) to work in interlocked
manner.
(0037] It should be noted that in the braking system (100), less force is required to
move the sub-link (113) of the second brake actuating means (103) and thereby actuating
the rear wheel braking device ( 1 09) upon the actuation of the first brake actuating means
( 102). Further, in the present embodiment of the braking system ( 100), the second brake
actuating means (1 03) does not move during the interlocked actuation of the front wheel
braking device ( 1 08) and the r~ar wheel braking device (I 09) by the first brake actuating
means (102).
Second Embodiment
(0038] In the second embodiment as depicted in Figure 2, a braking system (200)
comprises of inter-alia, of a front wheel braking device (208) such as a drum brake for
operating brake on a first wheel (116) (e.g., a front wheel), a rear wheel braking device
(209) such as a drum brake for operating brake on a second wheel (118) (e.g., a rear
wheel), a first brake actuating means (202) such as a brake lever mounted on the
handlebar of a vehicle, and a second brake actuating means (203) such as a brake pedal.
13
IPO DELHI 02-99-2015 17"12
The braking system (200) also comprises the I ink member (I 05) rotatably mounted on the
vehicle body frame thereof, and is provided with the biasing spring (II 0) which keeps the
link member (I 05) biased to the default position of the link member (I 05). Further, the
braking system (200) comprises a first connecting means (207) in the form of a cable, .
where the first connecting means (207) is employed to connect the first brake actuating
means (202) to the link member (I 05). Furthermore, the braking system (200) comprises
a second connecting means such as a front wheel connecting means (206F) (e.g., a first
wheel connecting means) and a rear wheel connecting means (206R) (e.g., a second
wheel connecting means).
[0039] In this embodiment, the front wheel connecting means (206F) is constituted
of a cable, and the rear wheel connecting means (206R) is a mechanical system. The
second brake actuating means (203) includes a sub-link (213), wherein the sub-link (213)
moves forward upon the actuation of the second brake actuating means (203). The rear
wheel braking device (209) can be actuated by pulling a metallic rod (211 ), where the
metallic rod (211) at one end (e.g., a first end) is connected to the rear wheel braking
device (209) and another end (e.g., a second end) is connected to the sub-link (213). The
sub-link (213) is further connected to the link member (I 05) by a wire rope (212).
[0040] When the second brake actuating means (203) is operated to be rotated
clockwise as indicated by arrow (B), the sub-link (213) moves forward pulling the
metallic rod (211) in the forward direction, thereby causing the actuation of the rear
wheel braking device (209) only.
[0041] When the first brake actuating means (202) is operated to be moved towards
the handlebar grip, the first connecting means (207) is pulled causing the link member
(105) to swing clockwise as depicted by arrow (A) in Figure 2. The clockwise swinging
of the link member ( 1 05) is adapted to cause the application of pulling force on the front
wheel connecting means (206F) rendering the front wheel braking device (208) operative.
Furthermore, the clockwise swinging movement ofthe link member (105) upon actuation
of the first brake actuating means (202), simultaneously or with a pre-determined delay
causes the sub-link (213) of the second brake actuating means (203) to move forward.
The forward movement ofthe sub-link (213) pulls the metallic rod (211) in the forward
direction causing actuation of the rear wheel braking device (209). Thus, actuation of the
14
IPO DELHI 92-99-2015 17 12
first brake actuating means (202) causes the front wheel braking device (208) and the rear
wheel braking device (209) to work in an interlocked manner.
