The structure of system of electrostart-up of the engine includes the storage battery, a starter, the traction relay, the ignition switch, the switch of blocking of a starter (only on cars with АКП), connecting wires and wires of the storage battery.
At ignition key turn in position of start-up of the engine the current of the storage battery moves in a winding of the traction relay of a starter. Thus there is a displacement of an anchor of the traction relay and the drive lever муфты a free wheeling, the drive gear wheel enters into gearing with a gear wreath of a flywheel. Contacts become isolated and the starter electric motor joins.
Presence муфты a free wheeling protects a winding and a collector of an anchor from a rating.
