TECHNICAL FIELD
[001] The embodiments herein relate to a brake pedal linkage mechanism for a vehicle, which is configured to be provided in at least one of a first position corresponding to a first driving position, and a second position corresponding to a second driving position. 5
BACKGROUND
[002] Vehicles such as tractors or other similar vehicles are primarily used in agricultural field operations. Tractors have two brake pedals, one brake pedal is a right brake pedal which is engaged by an operator to restrict the motion of the right rear wheels of the vehicle, and another brake pedal is a left brake pedal 10 which is engaged by the operator to restrict the motion of the left rear wheels of the vehicle. Brake pedal linkage mechanism in tractors is used for connecting the brake pedals (left and right brake pedals) to corresponding wheel brake units of the vehicle. Providing a brake pedal linkage mechanism in a vehicle having multiple driving positions is difficult and is one of the challenges posed to the 15 original equipment manufacturers (OEM).
[003] Therefore, there exists a need for a brake pedal linkage mechanism for a vehicle, which obviates the aforementioned drawback.
OBJECTS
[004] The principal object of an embodiment of this invention is to provide 20 a brake pedal linkage mechanism for a vehicle, which is configured to be provided in at least one of a first position corresponding to a first driving position in the vehicle, and a second position corresponding to a second driving position in the vehicle.
[005] Another object of an embodiment of this invention is to provide a 25 brake pedal linkage mechanism for a vehicle, which works in a same manner for a first driving position and a second driving position in the vehicle.

When the operator engages the left brake pedal 502La of the left brake pedal assembly 502L, the left brake pedal assembly 502L is angularly moved in a downward direction to rotate the brake pedal pivot shaft 504 in a predefined 5 direction (anti-clockwise direction) about the longitudinal axis of the brake pedal pivot shaft 504, and the brake pedal pivot shaft 504 rotates to angulary move the left brake pedal linkage 506 which pulls the second adjustable brake linkage assembly 512 which in turn pulls brake lever BR4 of the second wheel brake unit BR2 to actuate the second wheel brake unit BR2. Now, when the operator 10 engages the right brake pedal 502Ra of the right brake pedal assembly 502R, the right brake pedal assembly 502R is angularly moved in a downward direction to rotate the brake pedal pivot shaft 504 in a predefined direction (anti-clockwise direction) about the longitudinal axis of the brake pedal pivot shaft 504, and the brake pedal pivot shaft 504 rotates to angulary move the first right brake pedal 15 linkage 508F which pulls the first adjustable brake linkage assembly 510 which in turn pulls the brake lever BR3 of the first wheel brake unit BR1 to actuate the first wheel brake unit BR2.
[0034] Therefore, a brake pedal linkage mechanism 500 which works in a same manner for a first driving position and a second driving position in a vehicle 20 is provided.
