Abstract
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.
