    摘要： A variable displacement variable pressure vane pump system provides lubrication oil to a mechanical system. The system has a first control mechanism, which can be a control chamber directly acting on the control slider or a control chamber and control cylinder which acts on the control slider and a second control mechanism which is a control chamber and control cylinder which acts on the control slider. A control valve, operated by an engine control unit or other suitable control mechanism, selectively provides pressurized lubrication oil to the second control mechanism to allow the output of the pump system to more closely match the requirements of the mechanical system.

    摘要： A variable capacity vane pump has a housing defining a main chamber having an inlet port and an outlet port. A pump control ring (44) is moveable within the main chamber to alter the capacity of the pump. The control ring divides the main chamber into a pressurized region (45) and an unpressurized region. A vane pump rotor is rotatably mounted within the pump control ring. The vane pump rotor has a plurality of slidably mounted vanes engaging an inside surface of the pump control ring. The vane pump rotor has an axis of rotation eccentric from a centre of the pump control ring, whereby as the vane pump rotor rotates fluid is pressurized and moves from the inlet port to the outlet port. A control chamber (60,64) is provided between the pump casing and the pump control ring, and is operable to receive pressurized fluid to create a force to move the pump control ring to reduce the volumetric capacity of the pump. A return spring (56) acts between pump ring and the casing to bias the pump ring towards a position of maximum volumetric capacity. An opening (51) extends through the housing communicating with the unpressurized region, minimizes a clearance between the vane pump and engine on which the vane pump is mounted.

    摘要： A hybrid vehicle starting system includes a pinion gear driven by a starter motor, and a drive plate having a set of teeth in constant meshed engagement with the pinion gear. A one-way clutch drivingly interconnects the drive plate and an engine crankshaft and includes an inner race fixed for rotation with the crankshaft, an outer race fixed for rotation with the drive plate, and a plurality of rollers positioned radially therebetween. A cage positions the rollers in circumferentially spaced apart alignment with outer cam surfaces. A split ring is positioned within grooves on each of the inner race and the outer race. The split ring is fitted within one of the grooves at a first clearance and fitted within the other of the grooves at a predetermined second clearance at least ten times the first clearance to isolate the outer race from vibrations of the inner race.

    摘要： A starting system for a vehicle including an internal combustion engine having a crankshaft includes a pinion gear driven by a starter motor. A drive plate includes a set of teeth in constant meshed engagement with the pinion gear. A one-way clutch assembly is adapted to drivingly interconnect the drive plate and the crankshaft. The clutch assembly includes an inner race adapted to be fixed for rotation with the crankshaft, an outer race fixed for rotation with the drive plate, and a plurality of rollers positioned radially therebetween. One of the inner and outer races includes circumferentially spaced apart cam surfaces. The clutch assembly also includes a cage for positioning the rollers in a circumferentially spaced apart alignment with the cam surfaces and a roller bearing assembly positioned axially offset from the one-way clutch rollers to rotatably support the outer race on the inner race.
