Abstract:
A braking system in a vehicle comprises a front brake device disposed on first lateral
side, a rear brake device, and an integrated brake actuating means disposed on second
lateral side of vehicle. Brake actuating means is operatively coupled with rear brake
device. Braking system comprises an interlink member pivotally mounted to front body
portion of vehicle for coupling brake actuating means with front brake device. Interlink
member comprises first arm, and second arm coupled with first arm. First arm is
operatively coupled with brake ·actuating meahs on first lateral side and second arm is
coupled with front brake device frontwardly of a head tube in width direction of vehicle.
On actuating the actuating means, front brake device and rear brake device are actuated,
where front brake device is actuated due to movement of first arm and second arm about
a pivot point of interlink member on front body portion.

FIELD OF TECHNOLOGY
[0001] The present invention relates to braking system for vehicle.
BACKGROUND
[0002] Conventionally, m vehicles such as two-wheeled vehicles, braking
operation of a front wheel is actuated by application of force on a front wheel brake
actuating means. The front wheel brake actuating means is generally provided on a
handlebar of the two-wheeled vehicle (hereinafter interchangeably referred to as
'vehicle'). Further, braking operation of a rear wheel is actuated by application of force
on a rear wheel brake actuating means of the vehicle. The rear wheel brake actuating
means is· provided either on the handlebar or is provided in form of a foot pedal. The
operation of front and rear wheel braking is normally controlled, by the operator,
independently.
[0003] For safe braking of front and rear wheels of the vehicle, the balanced
actuation of front and rear wheel brakes is necessary. If only the front wheel brake is
applied, the rear wheel keeps rolling and the vehicle has the risk of being toppled. If only
the rear wheel brake is applied, the front wheel keeps rolling and the vehicle has the risk
of skidding.
[0004] Generally, in a combined braking system, where the front and rear wheel
brake devices are operated simultaneously, the front and rear wheel brake devices are
actuated by an integrated brake actuating means such as a brake pedal. By using the
integrated brake actuating means, the braking force is transferred from the brake pedal to
the front brake device and the rear brake device using a front brake connecting means
(e.g., a brake cable) and a rear brake connecting means (e.g., a brake rod). The brake
pedal is adapted to actuate the front and rear brake devices upon actuation of the brake
pedal by the user. One end of each of the front and rear brake connecting means is
connected to the brake pedal and the other end is connected to the respective front brake
device or the rear brake device. Typically, the brake pedal is provided on one side for
example right side of the vehicle, and the front brake device is provided on opposite side

for example. left side of the vehicle. Therefore, the front brake connecting means is
required to be routed from the right side of the vehicle to the left side of the vehicle,
resulting into transmission loss of the braking force.
SUMMARY
[0005] In an embodiment, a braking system in a vehicle is disclosed. The braking
system comprises a front brake device disposed on a first lateral side of the vehicle, a
rear brake device, and an integrated brake actuating means disposed on a second lateral
side of the vehicle. The second lateral side is opposite of the first lateral side. The
integrated brake actuating means is operatively coupled with the rear brake device. The
braking system also corp.prises an interlink member pivotally mounted to a front body
portion of the vehicle for operatively coupling the integrated brake actuating means with
the front brake device. The interlink member comprises a first arm, and a second arm
coupled with the first arm. The first arm is operatively coupled with the integrated brake
actuating means on the first lateral side of the vehicle and the second arm is coupled with
the front brake device frontwardly of a head tube of the vehicle and in a width direction
of the vehicle. Upon actuation of the integrated brake actuating means, each of the front
brake device and the rear brake device is actuated, wherein the front brake device is
actuated due to a movement of the first arm and the second arm about a pivot point of the
interlink member on the front body portion.
[0006] In an embodiment, the front body portion is a body frame of the vehicle.
The braking system further comprises a holder fixedly mounted to the body frame, and
wherein the interlink member is pivotally mounted to the holder around the pivot point.
In another embodiment, the front body portimi is the head tube and the braking system
further comprises a holder fixedly mounted to the head tube, and wherein the interlink
member is pivotally mounted to the holder.
. [0007] In an embodiment, the braking system further comprises a first connecting
means for connecting the first arm to the integrated brake actuating means, and a second
connecting means for connecting the second arm to the front brake device.

[0008] In an embodiment, the first arm comprises a first hole configured on a
first plane of the first arm on the first lateral side. The first connecting means is
connected to the first arm through the first hole. The second arm comprises a second hole
on a second plane of the second arm in the width direction and in the second lateral side
of the vehicle, where the second plane is substantially perpendicular to the first plane.
The second connecting means is connected to the second arm through the second hole.
Further, when the integrated brake actuating means is actuated, the first hole of the first
arm rotates about the pivot point in a rearward direction of the vehicle such that a pulling
force is applied on the second arm and the second hole muves in a gubstnntially vertical
direction thereby applying the front brake device.
[0009] In an embodiment, a location of the second hole is vertically below a
location of the first hole. In an embodiment, the braking system further comprises a third
connecting means for connecting the integrated brake actuating means to the rear brake
device.
[0010) In an embodiment, the braking system compt:ises a front brake lever, and
a fourth connecting means for connecting the front brake lever to the front brake device.
[0011] In an embodiment, the second arm comprises a third hole configured in
the width direction. The braking system further comprises a front brake lever, and a
fourth connecting means· for connecting the front brake lever to the second arm through
the third hole.
[0012] In an embodiment, the.first arm and the second arm form a substantially
'L' shaped structure.
[0013) In an embodiment, the interlink member is biased with a biasing force
applied by a biasing spring for rotationally urging the interlink member against a load
acting on the interlink member from the integrated brake actuating means or a front
brake lever.
[0014] In an embodiment, the first lateral side lies on a first side from a
longitudinal axis of the vehicle and the second lateral side lies on a second side from the
longitudinal axis, where the longitudinal axis passes through a centre of the vehicle.
