摘要： A control clutch mechanism embodying a first aspect of the invention has an inner clutch part and an outer clutch part defining an annular space therebetween, with a viscous control unit and a frictional clutch unit being provided which consist of two sets of plates arranged in the annular space, each set of plates including plates alternately nonrotatively connected with one of the clutch parts, respectively. An axially movable annular piston is slidingly arranged in fluid-tight engagement between the viscous control unit and the frictional clutch unit and a pressure plate is located between the annular piston and the frictional clutch unit. A first stop is provided for the annular piston and a first spring acts between the piston and the pressure plate. The viscous control unit is structured to transmit a negligibly low nominal torque as compared with the frictional clutch unit and, in accordance with a second aspect of the invention, the frictional clutch unit is provided with an annular flange which is moved by operation of an electromagnet against a second spring and against a second stop so as to relieve the pressure on the first spring, thereby bringing the control clutch mechanism into a freewheeling state by energization of the electromagnet.

摘要： A device for transmitting torque between two rotatable shaft members (2, 3) in a stationary housing (1) contains a number of alternate clutch discs (10, 11) engageable to counteract differential rotational speed between the two shaft members, to which they are connected, a hydraulic clutch piston (12) to engage the clutch discs and a hydraulic pump arrangement (15-24) driven by the speed differential between the two shaft members. An annular control piston (15) is axially movably arranged in the housing and is in contact with control pins (17), which are rotatable together with one of the shaft members (3) and cooperate with a cam curve (20) in the other shaft member (2) in such a way that the control pins and thus the control piston are imparted an oscillating movement with a frequency directly proportional to the rotational speed differential between the two shaft members.

摘要： A spur gear differential (1) lockable to a limited extent and used as a differential gear for a motor vehicle. The differential makes use of the friction losses resulting from the oil flow conveyed by the teeth and teeth gaps of the planetary gears (6) and the sun gear (2) or the hollow gear (3). For control purposes, a cover ring (16) is provided which may be moved into a close position, i.e. a sealing position, relative to the end face (17) of the gear teeth or away therefrom to throttle or release the oil flow.

摘要： The differential has a differential housing (21) driven by an engine and a bevel gear differential drive mechanism (31) with radially extending bevel pinion shafts (35) supported within the housing. Bevel pinions (37) are rotatably supported on the shafts. A pair of driven gears (39, 41) is arranged on both sides of the pinion shafts and meshed with the appropriate pinion. A differential limiting device (55) is connected with one of the driven gears (41) and a transmission drive (67) is positioned between the differential limiter and the other gear (39). USE/ADVANTAGE - Bevel gear differential drive for vehicle allows driven shafts to be used without alteration for other differentials of different type.

摘要： A transmission unit particularly intended for use as a differential between driven axles of a vehicle comprises an epicyclic gear train having three rotatable members, specifically, an input member connected to an input shaft, a second member connected to one section of a liquid friction coupling, and an output member connected to an output shaft. To avoid an occurrence of constraining torques as the vehicle is steered and to permit a modulation within a wide range of the relationship between the speed difference between the sections of the coupling and the torque limit of the transmission unit, the second section of the liquid friction coupling is non-rotatably connected to a stationary structure of the transmission unit, specifically to a housing of the epicyclic gear train. Alternatively, said second section of the coupling may be adapted to be held against rotation by a brake, so that the axles of the vehicles can easily be uncoupled from each other. Output torque is delivered from the transmission unit only by the output member of the epicyclic gear train.

摘要： A differential gearing, in which the torque introduced via an input shaft is distributed equally to two driven shafts, is constructed as a spur gear differential and has a pinion arrangement as the locking mechanism in which the pinions and spur gears work as geared pumps. The pump moment is directly the locking moment, with the hydrostatic pressure developed being reduced by precisely dimensioned clearances without any further control devices being required. A special arrangement of the pinions in a housing guarantees an equal locking moment in both directions of rotation.
