Abstract
An improved gear transmission (10) includes a one-way clutch (52) for connecting together selectively two drive elements to establish a plural torque flow path through the transmission (10) and the clutch (52) includes at least one inner race (52B) and one outer race (52A), each of the races having coaxial inner and outer race portions, the outer surface (112) of the outer race portion (52B) defined by a first undulating surface, the inner surface (113) of a mating drive element defined by a second undulating surface in conjugate registration with the first undulating surface, the profiles of the first and second undulating surfaces (112,113) being controlled to provide a controlled clearance therebetween reducing shock loading at the interface of the inner and outer race portions through a gradual lock-up through a controlled wind-up of the mating members and reducing vibration in the gear elements.
