An improved rocker system for actuating valve lift events of an internal combustion engine is provided. The system includes a rocker arm and an actuator link with the actuator link arranged to be in constant driving engagement with the rocker arm and a camshaft. A rocker shaft is positioned in a cylinder head and oriented to have a rotational axis that is substantially perpendicular to a rotational axis of the camshaft and the rocker arm is arranged to be rotated about the rocker shaft and engage a valve to actuate valve lift events of the internal combustion engine.

A valve deactivator is provided that is capable of being activated and deactivated by a pulse energy input. The valve deactivator includes an input member and an output member which are movable relative to one another in the deactivated mode and which are engaged for simultaneous movement in an activated mode. A coil and armature, or other pulse energy input means, are provided to engage and disengage a locking system to activate and deactivate the valve actuator.

A pendulum absorber system attenuates torsional vibrations within a drive train of a vehicle. The system can be incorporated between an engine and an automatic transmission, for example, within a flex plate assembly attached to an engine's crankshaft, within a pump housing cover of a torque converter, or as a stand-alone unit between a flex plate assembly and a torque converter. The system includes at least one pendulum weight that dynamically moves along a predetermined path in response to variations in rotational velocities of a housing of the system and that is tuned to attenuate excitation of torsional vibrations within the drive train. A limiter assembly, which can include multiple limiters, is provided within the system for stopping movement of the weight when it reaches endpoints of the predetermined path, by mechanically impeding further movement at both of a first and second end of the weight.

An engine drive assembly includes a camshaft gear, and a first idler gear engaged with the camshaft gear. The engine drive assembly further includes a crankshaft gear engaged with the first idler gear and a second idler gear assembly engaged with the crankshaft gear. Additionally, the engine drive assembly includes a balance shaft gear engaged with the second idler gear. The crankshaft gear drives the camshaft gear via the first idler gear and the crankshaft gear drives the balance shaft gear via the second idler gear assembly.

An oil cooling arrangement for a stacked plate type clutch assembly is provided. The stacked plate clutch assembly includes a stacked plate arrangement of alternating separator plates and clutch plates housed within a retainer. The oil cooling arrangement includes a flow passage structure arranged relative to the retainer for providing a secondary oil flow path in addition to a flow path through the stacked plate clutch assembly.

A north-south transaxle includes a case having a first passageway extending longitudinally, a second passageway spaced from the first passageway and being generally parallel to the first passageway and extending longitudinally, and a cavity at one end of the second passageway having an opening generally perpendicular to the second passageway. The transaxle also includes a transmission assembly disposed in the first passageway, a transfer assembly disposed in the second passageway and a structure interconnecting the transmission assembly and transfer assembly for transferring torque from the transmission assembly to the transfer assembly. The transaxle further includes a differential assembly disposed in the cavity and the transaxle is structured to thermally compensate preload on the differential assembly over a temperature operating range.

A push-pull clutch apply piston of a four-speed automatic transmission which utilizes a clutch apply piston with a single pressure plate being pushed by fluid pressure in one direction for applying a clutch assembly and being pulled in an opposite direction for applying an adjacent clutch assembly. The piston has an axially extending flange at an outer periphery thereof, and at least one pressure plate retained to the flange.

A variable compound rocker system for varying the lift of intake valves of an internal combustion engine is provided. The system comprises a rocker shaft with eccentric rings non-rotatably attached thereto. Furthermore, the system includes primary rockers non-rotatably attached to the eccentric rings. The primary rockers have engaging surfaces for engaging rollers attached to secondary rockers. The rollers enable the primary rockers to actuate the secondary rockers, thus actuating the intake valves. The system further includes an actuator assembly adapted to incrementally rotate the rocker shaft, and thus the primary rockers. This incremental rotation of primary rockers changes their attitude causing the lift of the intake valves to vary, thus varying the engine performance characteristics.
