FREE-RUNNING DRIVE FOR THE STARTER OF AN INTERNAL COMBUSTION ENGINE

摘要

A free-running drive has an outer ring body (1) connected by a flange (2) to a starter shaft-receiving sleeve (3) so as to form a single piece therewith. This single piece forms a housing which contains the inner ring body (5) linked by a radially projecting flange (6) to the starting pinion (7) so as to form a single piece therewith. This part formed in a single piece has on the outer circumference of the inner ring body (5) curved paths (11) that extend eccentrically to the axis. Rolling bodies (9) urged by leaf springs (10) lie against these curved paths and the circular inner circumference of the outer ring body (1). The leaf springs (10) are held each in a spring seat (12) of a ring-shaped spring guide (13) secured against rotation to the inner ring body (5) and lying against the flange (6). The advantages of this design are the less expensive manufacture of the inner ring body (5) provided with curved paths (11) and the reliable operation of the free running drive even under very high loads.
