Transmission shifting apparatus

摘要: Apparatus for clutching two rotatable elements together. The are mounted rotation about respective axes and selectively coupled together by a shifter clutch member. member is preferably splined to one element so as rotate therewith be axially movable in out of engagement. other the provided with teeth on their facing sides which may engaged couple this and, turn, According invention, continuous, spaced, lateral engaging surfaces extending generally perpendicular its axis rotation. These coact corresponding mating an shifting element, through intermediary antifriction bearings. thus effective apply axial force shift applying uniform pressure against surfaces.
