2. OPERATION
(1) Front Axle Case
(2) Brake Cam Lever
(3) Brake Cam
The brake body is incorporated in the front axle case (1) filled with transmission oil and is designed to brake when
the brake disc (7) splined with the differential gear shaft (9) is pressed against the actuator (6) by means of the cam
mechanism incorporating steel balls (5).
For greater braking force, three brake discs (7) are provided at the right and left sides respectively, and the friction
plates (4) fixed to the front axle case is arranged between the brake discs (7).
During Braking
When the main brake pedal is pressed, the linkage causes the brake cam lever (2) and brake cam (3) to turn into
the direction of arrow shown in the above figure.
Therefore, the actuator (6) also moves the direction of arrow. At this time, since the actuator (6) rides on the steel
balls (5) set in the grooves of the front axle case to press the brake discs (7), the differential gear shaft (9) is braked
by the frictional force generated by the actuator (6) and brake discs (7).
