<p>An improved hydraulically-actuated locking differential includes a retainer ring (30) that is threadably connected with the axle housing (4) for adjustably supporting the bearings (28) at one end of a differential casing (2), which retainer ring (30) contains ducting for supplying pressure fluid to a hydraulic actuator (46,48) contained within the casing (2), to thereby activate a friction pack assembly (36) to lock a side gear (18) of the differential to the differential casing (2). The ducting for the hydraulic fluid includes a first passage (56) contained in the retainer ring (30), a second longitudinal (60) passage contained in a tubular end portion (2A) of the casing (2), and a third passage which affords continuous communication between the first (56) and second (60) passages during rotation of the casing (2) relative to the axle housing (4).</p> |
