Drehmoment übertragende Vorrichtung

摘要

A control member (9) of a torque transmitting apparatus is composed of pins (11), a retainer (12), a first and a second arc-shaped gears (10,14) which are formed from a single ring gear divided by a plane including an axis of the gear, a piston (13), first springs (27) and second springs (15). The first and second arc-shaped gears (10, 14) are biased respectively by the first and second springs (27, 15) in opposite directions so that the splines (10a, 10b, 14a, 14b) of the first and the second gears are deviated from each other while they are in mesh with corresponding splines (7a, 4a) of a sprocket sleeve (7) and a cam sleeve (4). As a result, rattling noise due to backlash of the splines is suppressed even when torque change is transmitted to the sprocket sleeve (7).
