ABSTRACT:
A reverse idler gear lever pivots to move a reverse gear into engagement with an after-running gearwheel mounted on a layshaft. A connecting arm is pinned to the idler lever and defines a slot within which a pin mounted on a brake lever moves. The pin engages a bowspring within the slot and transmits a force to the brake lever until the bowspring is cleared by the pin. The spring force operates to pivot the brake lever and to bring a brake surface into abutting contact with the after-running gearwheel. Alternatively, a spring force is developed on a cam surface as the brake lever moves relative to the connecting arm.
