Speed differential device of double overrunning clutch device

Abstract

A speed differential device of a double overrunning clutch device includes: a left input unit, an left output ring with cam, a right input unit, a right output ring with a cam; and double overrunning clutch device between the left output ring and the right output ring. The double overrunning clutch device includes a left clutch unit and a right clutch unit; and a synchronous unit is installed between the left clutch unit and the left output ring, and between the right clutch unit and the right output ring. The synchronous unit has a left synchronous ring and a right synchronous ring, but rotate independently; an inner surface of each of the left synchronous ring and the right synchronous ring is formed with teeth or tilt teeth; and an outer annular surface of each of the left synchronous ring and right synchronous ring is formed with teeth or tilt teeth.
