摘要： An improved lubrication system for a ball ramp master clutch and a gear change transmission is disclosed where a lubricant pump is driven by the input shaft to a ball ramp mechanism which, when energized, applies a clamping force on a clutch pack where lubricant is supplied to the pump from a wet sump on the transmission and then lubricant is forced into the clutch assembly and also forced into the gear shaft transmission for eventual return into the sump for recirculation. In an alternate embodiment, a dry sump system is used where the oil flowing out of the transmission is pumped to dry sump where it is then recirculated to the pump.

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.
