BRAKES L4100, WSM

(EU)
2. OPERATION
The brake body is incorporated in the brake case (4) filled with transmission oil and is designed to brake when
the brake disc (3) splined with the differential gear shaft (6) is pressed against the cam plate (1) by means of the cam
mechanism incorporating steel balls (5).
For great braking force, two brake discs are provided at the right and left sides respectively, and the steel plate
(2) fixed to the brake case is arranged between the brake discs.
Q
During Breaking
When the brake pedal is pressed, the linkage causes the brake cam lever (8) and brake cam (7) to turn into the
direction of arrow shown in the above figure.
Therefore, the cam plate (1) also moves the direction of arrow. At this time, since the cam plate (1) rides on the
steel balls (5) set in the grooves of the transmission case to press the brake disc (3), the differential gear shaft (6) is
braked by the frictional force generated by the cam plate (1) and brake disc (3).
