Abstract: A differential gear has a locking ring which is axially displaceable along an axis between a locked position in which it interlocks a dish (serving as a carrier) and a bevel gear, and an unlocked position in which the bevel gear is released. The ring is displaced by pivoting a yoke about an offset, upright pin. Pivoting the yoke is by means of a diaphragm connected via a pin to the yoke. The diaphragm is selectively subjected to vacuum. The diaphragm is attached to a cover of a housing of the differential gear.

Abstract: In a clutch (6) for locking a differential gear for a vehicle, a movable half (60) of the clutch (6) is pushed indirectly via a sliding sleeve (70) and intermediate members (77) in an engaging direction. Then the sliding sleeve (70), with a locking surface (74), retains the intermediate members (77) firmly in a locking position between a bearing surface (64) of the movable half (60) and an axially stationary retaining surface (4). Flanks (52, 62) of clutch teeth (51, 61) of an axially stationary half (50) and of the movable half (60) form in the axle direction a deflection angle (55). The bearing surface (64) and the retaining surface (4) form a wedge angle (65). The locking surface (74) of the sliding sleeve (70) is inclined in an axial direction forming a small releasing angle (75). To open the clutch (6), the sliding sleeve (70) is pulled away. A torque produces through the deflection angle (55) an axial deflection force which then disengages the clutch (6). The intermediate members (77) are, at the same time, pushed out of their locking position by the wedge angle (65). A small retaining force and a small releasing force on the sliding sleeve (70) are sufficient to keep engaged and to disengage the clutch (6) even against maximum torque.

Abstract: A vehicle differential includes a clutch assembly and a hydraulic actuator for selectively preventing relative rotation between a pair of vehicle half axles. The differential assembly has an outer housing rotatably mounting a gear case and ring gear therein. A planetary gear assembly is coupled between the gear case and one half axle. The planetary gear assembly is also coupled to a sun gear which in turn is coupled to the other half axle. The clutch assembly is coupled between the gear case and the sun gear. An annular manifold is fixedly mounted in the outer housing and sealingly engages an outer surface of the gear case for supplying pressured hydraulic fluid to actuate a piston in a cylinder formed in the gear case which in turn actuates the clutch assembly. The pressure of the hydraulic fluid determines a range of torque differentials for which the clutch assembly will prevent relative rotation between the half axles.

Abstract: A differential gear unit includes a viscous coupling for restricting the differential rotation of output gears (27, 29), with the conneciton of one of the parts (31) of the viscous coupling to one output gear being by way of a releasable connecting device so that the viscous coupling can be brought out of operation when required, e.g. under vehicle braking. The connecting device comprises a sleeve (1), coupling members (11) movable radially in the sleeve (1) to engage, when in radially outermost positions, groove (35) for torque transmission, and an actuating member (2) movable axially within the sleeve and operable on the coupling members. The actuating member (2) is movable by an axially displaceable positioning member (87, 49) through the intermediary of latching balls (68, 48) which are themselves radially displaceable to hold the actuating member in position without continuous application of a high force. The positioning member may be movable mechanically, electro-magnetically, or by fluid pressure.

Abstract: An automatic differential locking system for a working vehicle having steerable front and rear wheels, which includes a selector for selecting a steering mode of the vehicle, an actuator for operating a differential locking mechanism, and a gate for sending a control signal to the actuator in response to a signal received from the selector. The gate is adapted to send a differential locking signal to the actuator upon receipt of a parallel steering mode signal from the selector. In response to the differential locking signal the actuator actuates the differential locking mechanism. Since differential revolutions of the wheels are limited at times of parallel steering, the vehicle is capable of accurate course revisions and alterations without slipping.
