At turn of a key in the ignition switch in the provision of start-up tension to contact of the electromagnetic traction relay installed in the top part of a starter moves. The anchor of the traction relay is involved, via the lever of the drive moves a gear wheel with the coupling of a free wheeling and enters it into gearing with a gear wreath of a flywheel. After gearing of a gear wheel with a gear wreath of a flywheel the electric motor of a starter which turns a bent shaft of the engine turns on. After launch of the engine the frequency of rotation of a gear wheel exceeds the frequency of rotation of an anchor of a starter, and the coupling of a free wheeling does not transfer torque from an engine flywheel to a shaft of an anchor of a starter (fig. 7.32).
