摘要

An automotive transmission system has a disc (64) rotating about an axis (A) on a shaft. The disc (64) has a number of chambers (58) holding a ball-shaped mass balance (50) which rests on a race (52). The chamber has an essentially semi-circular crown zone between a wide zone (56, 58), the opposite face being truncated.
