Starting system

Start system includes the battery, a starter, the traction relay, ignition switch, locking switch (only on cars with automatic gearbox) and wires.

The starter is activated by pulling the starter relay coil current begins to flow from the battery, the relay anchor is pulled and the relay contacts are closed. Simultaneously the relay anchor through the lever moves the overrunning clutch with the gear. The freewheel hub rotates helical splined shaft together with the starter pinion, which facilitates its entry into engagement with the flywheel. Through the closed contact magnetic switch is current feeding the stator winding and the armature, the armature and the starter starts to rotate along with the hub, and the overrunning clutch.

Once the engine starts, the rotational speed gear exceeds the speed of the armature starter freewheel rotates freely and no torque is transmitted from the flywheel to the starter shaft. After releasing the ignition feed circuit winding traction relay opens, the anchor of the traction relay is wrung out by a spring in its original position, the relay opens and the drive gear is disengaged from the flywheel.
