  • Brake/differential lock pedal linkage
    Patent number: 8056697
    Abstract: A brake/differential lock pedal linkage includes a two-stage manual control that may lock a differential before progressively engaging a brake. The manual control may be a foot pedal or hand lever. The linkage may include a brake cam lever that pivots on a brake cam shaft in response to movement of the manual control, a differential lock link connected between the brake cam lever and an actuator that can move a differential lock shaft to lock the differential, and a lost motion coupling between the brake cam lever and the actuator allowing the brake cam lever to pivot to a differential lock position in which the actuator moves the differential lock shaft sufficiently to lock the differential, before the brake cam lever pivots further to progressively engage the brake.
