10.5.1. Features of a design

The starter of the Chevrolet Lanos cars represents the quadripolar, four-brush electric motor of a direct current with excitement from permanent magnets combined with a planetary reducer and the electromagnetic dvukhobmotochny traction relay. Covers and the case of the stator are pulled together with two bolts. Permanent magnets are fixed in the case of the stator. Rotation from a shaft of an anchor of the electric motor is transmitted to a drive shaft through a planetary reducer. On a shaft of the drive the roller coupling of a free wheeling is installed.

At turn of a key in the switch (lock) of ignition in situation "START" tension from the rechargeable battery moves on the involving and holding windings of the traction relay, as a result the lever of the drive moves and the gear wheel of a starter enters gearing with a gear wreath of a flywheel of the engine. At the same time the anchor of the traction relay closes power contacts (at this moment the involving winding is switched off), on the electric motor of a starter tension from the rechargeable battery moves. The starter anchor through a planetary reducer turns a bent shaft of the engine. After launch of the engine when the frequency of rotation of a gear wheel exceeds the frequency of rotation of a shaft of a starter, the coupling of a free wheeling will be unblocked and probuksut, thereby protecting a starter from the high frequency of rotation and damages.

    

USEFUL TIPS To avoid many malfunctions of a starter, follow a number of simple rules at its operation. At launch of the engine include a starter no more than on 10-15 with and repeatedly — through 20–30 pages. Continuous long work of a starter can lead to an overheat. If after three attempts the engine is not launched, then it is necessary to check and eliminate malfunctions in a power supply system or in system of ignition of the engine. After launch of the engine immediately switch off a starter as long rotation of a gear wheel of the drive a flywheel can lead to jamming of the obgonny coupling of a starter. It is not allowed to move the car by means of a starter. It causes its considerable overload and damage.
