ABSTRACT:
A reversing clutch mechanism (10) for use in a transmission (12) of the type having a continuously rotating input shaft (52) and a rotatable output shaft (20). A pair of friction clutches (48, 50) are rotatably disposed on the output shaft (20) and are continuously driven in opposite reverse and forward rotational directions by gears (54, 58) and sprockets (60, 62) associated with the input shaft (52). A double friction cope (94) is helically splined on the output shaft (20) and moveable toward and away from the friction clutches (48, 50) for selective frictional engagement with either friction clutch (48 or 50) to cause the output shaft (20) to rotate in either a forward or reverse rotational direction. The double cone (94) includes a peripheral shifting groove (112) having oppositely inclined side walls (114) which cooperate with a shifting pin (120) disposed in the groove (112) to disengage the double cone (94) and the friction clutch ( 48 or 50). The double cone (94) also includes a ridge (148) disposed in the groove (112) and having a concentric top surface (150) to prevent the shifting pin (120) from extending into the groove (112) beyond the top surface (150).
