摘要： A closed hydraulic system (22) is provided for transmitting steering movement to a rear wheel steering assembly (16) in response to steering movement of a front wheel steering assembly (14). The front wheel steering assembly is controlled by a steering wheel (18) and a power steering assembly (20). The closed hydraulic system (22) includes a pump assembly (56) and an actuator assembly (58) connected together by conduits (60,62) to define closed fluid flow branches (164,166) for moving a piston (112) in the actuator assembly in response to movement of a piston (78) in the pump assembly. Movement of the actuator piston is transmitted to the rear wheel steering assembly via first and second cam assemblies (122,124) which effect same direction rear wheel steering for rather small front wheel steering angles and which effect opposite direction rear wheel steering for greater front wheel steering angles. Pump assembly (56) includes first and second neutral valves (92,94) for intercommunicating opposite sides of the pump piston (78) with a chamber ( 83) when the piston is in a neutral position. System (22) also includes a reservoir (68) disposed above the normal fluid level of the system and exposed to atmospheric pressure.

摘要： A driveline master clutch assembly is disclosed where a unidirectional ball ramp mechanism is used to apply a clamping load to a clutch pack for frictionally coupling a prime mover such as an engine to a gear change transmission. The ball ramp mechanism includes index plates to limit the rotation of a control ring and an activation ring such that the energized ball ramp mechanism increases in separation distance to increase the clamping force on the clutch pack whenever there is slippage in the clutch pack irregardless of the direction of torque flow through the master clutch assembly.

摘要： In a transmission inertia brake a ball ramp mechanism is used to load a clutch pack to slow a rotating transmission shaft where the clutch pack is carried on a one piece drive assembly having a gear section for meshing with a transmission gear, an extension section for engaging a thrust plate in an isolator assembly, a clutch section for engaging plurality of driven clutch plates in the clutch pack and a bearing section for rotational support within a brake housing. An armature having an angled peripheral surface engages a mating friction surface formed in an end plate to form a core clutch, the armature being magnetically pulled upon energization of an electrical coil energized by a power signal from a control unit supplied through a sealed electrical connector thereby introducing a frictional braking force on the armature to activate the ball ramp mechanism. The armature is nonrotatably connected to the control ring of the ball ramp mechanism through at least one connecting pin. A Belleville spring is used to apply an axial load on the ball ramp mechanism and to drive the star in a gerotor oil pump which interacts with a ring to pump cooling lubricant throughout the clutch pack in the ball ramp mechanism.

摘要： A differential gear mechanism including a clutch assembly (35) for retarding rotation between a side gear (23) and a gear case (11,45), and a ball ramp actuator for actuating the clutch assembly. The ball ramp actuator includes an inner actuating plate (49) within the gear case, and an outer actuating plate (51) disposed external to the gear case. In order to initiate ramp up of the ball ramp device, an electromagnetic coil assembly (67) includes an annular coil (75) which is disposed in face-to-face relationship with the outer actuating plate (51). An annular drive plate (83) is disposed between the coil (75) and the outer actuating plate (51), and is drawn into frictional engagement with a layer of friction material (81) upon energization of the coil. The drive plate (83) is connected by pins (89) to be axially movable relative to the outer actuating plate, but fixed to rotate therewith, such that frictional engagement of the drive plate (83) retards rotation of the outer actuating plate (51).
