Abstract
A transmission clutch module includes an inner race, an outer race, and a plurality of race engaging pawls adapted to selectively secure the races together in either a locked position or an unlocked position. The clutch module includesan actuator cam configured to be moved between two angularly spaced positions to control the pawls. The inner race is comprised of two axially spaced inner race plates axially secured together by rivets for retaining, and accommodating angular limited movements of the pawls. The pawls are circumferentially disposed about the inner race plates, and are radially outwardly biased by springsto engage the outer race, unless blocked by the actuator cam. The pawls are weighted at one end, so that at a threshold speed of the inner race, they can overcome spring resistance to disengage from both the actuator cam and the outer race.
