ABSTRACT:
A vehicle drive mechanism as shown and described includes both a differential lock and an operating mechanism therefor, and a parking brake and an actuator mechanism therefor, in which the mechanism is constructed and arranged so that the differential lock mechanism can be actuated to lock out the differential without applying the parking brake so that application of the parking brake always locks out the differential. This may be accomplished by means of an actuator mechanism which includes a mechanical linkage extending from a parking brake piston surrounding the input shaft of the vehicle to a slidable member which engages a differential locking member in order to lock the differential. This linkage includes a slotted link which permits actuation of the differential lock independently of the vehicle brake, while inter-locking the vehicle brake actuator with a differential lock actuator so that setting the vehicle brake will always lock the differential.
