Abstract
A drive axle differential has the shift fork for the differential locking curvic clutch collar slidably received over a push-rod and registered against a flange on the push-rod. The push-rod has one end slidably received in a bore in the differential carrier and the other end threadedly engaging an air pressure power piston. A slot is provided in the threaded end of the push-rod for an adjustment tool and a locking screw is threaded against the push-rod after adjustment. The piston cover containing the air pressure control signal port then attached to the differential carrier.
Claims5
An adjustable locking mechanism for a drive axle differential comprising:
- (a) an axle carrier having a drive pinion journalled thereon and a differential carrier driven by said pinion and having oppositely directed axle shaft journalled therein with each shaft having a side gear drivingly attached thereto and engaged by a pair of power dividing spider gears journalled on said case;
- (b) means defining curvic clutching surfaces on said carrier and rotatable therewith;
- (c) an annular clutching member drivingly disposed on one of said axle shafts and axially movable thereon for engaging and disengaging said curvic clutch surfaces;
- (d) an actuator member movably disposed with respect to said housing and operable, upon movement between a first and second position, to effect said engaging and disengaging of said clutching member;
- (e) pressure-responsive means operably connected to said actuator member for, in response to an air pressure signal, effecting movement of said actuator member;
- (f) means for adjusting the connection of said pressure-responsive means with said actuator member comprising a push-rod rotatably received through an aperture in said member and threadedly engaging said pressure-responsive means wherein said means for adjusting the connection extends through a housing, said housing encloses said adjustable locking mechanism and said means for adjusting is adjustable from outside of said housing.
