ABSTRACT:
A starter includes two electric drive motors (1, 2), with parallel axes (3, 4), coupled to the same reduction gear (11, 14) whose output shaft (15) is connected to a single Bendix starter (18). Shaft (6) of one of the motors (1) exhibits a reversible thread (23) on which is mounted a nut pinion (7), engaged with a gear wheel (11) of the reduction gear and further connected to control lever (27), which is connected to Bendix starter (18). When first electric motor (1) is started, nut pinion (7) is braked in rotation by passive resistances, and therefore moved axially, which, by lever (27), causes the advance of Bendix starter (18), bringing pinion (21) of the latter to engage with ring gear (22) of the internal combustion engine.
