Dynamic shock absorber arrangement for clutch mechanism

摘要

The friction part of a main clutch (3) is connected between an engine crank shaft (8) and a gear input shaft (9). A mass part (11) rotates with the gear input shaft. A bottom clutch (13) is joined to the mass art and can be connected to the gear input shaft. The bottom clutch has a position correction mechanism (32) for compensating for wear on the main clutch's friction part. An elastic part (12) connects the gear input shaft and mass part in a rotary direction. The position correction mechanism is in the form of a free wheel coupling with a pair of free wheel engaging parts (34) immovable in one direction and movable in the other.
