ABSTRACT:
A differential assembly has a rotatable, open sides casing into which the opposite, splined ends of axial shafts extend. Each axial shaft has a splined collar ring mounted upon it and a surrounding coupling ring. A drive rod, secured to the casing, extends between the opposed coupling rings and has wedge shaped surfaces fitted within aligned V-shaped notches formed on facing surfaces of the coupling rings. Disk plate type clutches releasably connect each of the coupling rings to their adjacent collar rings. The clutches include Belleville spring washer plates which resiliently force the coupling rings inwardly against the drive rod for maintaining the rod wedge shaped surfaces in face to face contact with their adjacent notch walls. The coupling rings, clutches and collar rings are assembled into the casing through its open side and thereafter, the rod is inserted endwise into the casing, between the coupling rings, through a rod receiving hole in the casing. When the casing rotates, the drive rod wedge surfaces drive the coupling rings and also, press them outwardly for connecting the clutch for engaging the coupling rings with the collars to rotate the axles. If either axle rotates faster than the casing, the outward pressure of its rod wedge surface against its coupling ring notch is momentarily relieved and therefore, its clutch is temporarily disconnected so that axle may free wheel until it returns to the casing speed.
