摘要： A center differential (17) including a clutch pack (33), a cam ramp actuator (31) for moving the friction discs (65,67) toward an engaged position, and a viscous coupling (29) which will have a “slip speed” representative of the speed difference between the front (11) and rear (23) wheels. There is a one-way clutch (57) disposed between the output (49) of the viscous coupling (29) and the first ramp plate (51) to transmit positive torque when the vehicle is in a forward gear, but negative torque is not transmitted, for example, during braking. An override mechanism (55) is provided, including a plurality of spring biased pins (107), such that, below a predetermined speed of rotation, positive torque can also be transmitted when the vehicle is in reverse gear. The pins (107) are associated with flyweight members (97) so that, above the predetermined speed, the pins are disengaged, and positive torque can be transmitted only in forward gear.

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.
