Abstract

The engine starter motor has a free wheel in which the driving member forms the track for the pawls (9). The pawls are fitted between arms (8) which project axially from the end face of the driving member. The springs (11) press against one end (9b) of the pawls so that they pivot about the other end (9a) and press the balls (12) against the driven shaft (6) and so transmit the drive by friction. As the speed increases the centrifugal force on the pawls causes them to move outwards and overcome the force of the springs. The balls then are no longer pressed against the driven shaft and the drive no longer transmitted.
