A locking differential includes a pair of opposed collinearly arranged annular clutch members the adjacent faces of which contain corresponding pai rs of V-shaped drive grooves for receiving a cylindrical drive pin that is connect ed with the differential casing, the planar faces of the drive grooves being arrange d at an obtuse angle of about 120.degree.. Preferably, in order to obtain line-to-li ne contact with the drive pin, each of the four planar drive faces of a clutch member has an angle of convergence of about 3.017.degree. relative to the diametrically arranged lines of juncture of the associated pairs of planar drive faces. The clutch members a re normally biased apart by helical springs the end portions of which are received in pockets contained in the opposed faces of the clutch members, respectively. Access slots are provided in the outer circumferential surfaces of the clut ch members for introducing the ends of the spring members, when the spring members are in an axial ly compressed assembling condition, into the respecti ve pockets. A locking pin carried by each clutch member on the face thereof opposite the other clutch member extends within a corresponding locking groove that i s contained in the opposite face of, and communicates with the outer circumferential surface of, the otherclutch member. |
