The brakes are provided on the power transmitting shafts (brake shafts (8)) through which power is transmitted
to the final reduction system. The brakes are incorporated in the brake case (1) filled with transmission oil. They are
designed to brake when the brake discs (2), spline-coupled and rotating with the brake shaft, are pressed against the
brake case by cam plate (3) with the cam mechanism incorporating steel balls (4). For greater braking force, two brake discs are provided respectively, and the plate (6) fixed to the brake case are arranged between the brake discs.
During Braking
When the brake pedal is pressed, the force causes the brake cam lever (5) to move in the direction of allow through the brake rod. At the same time, the brake cam (7) spline-couples with the brake cam lever also moves. Due to this force, cam plate (3) moves in the direction of arrow. Since the steel balls (4) are set in the grooves of differential case, cam plate (3) is pushed out against the brake discs (2), causing braking with the friction force created.
