20.1. The general data

The steering consists of a steering wheel, a steering column, the mechanism of a steering and cross-section steering draughts. For convenience of driving steering wheel adjustment on height is provided.
The steering wheel is fixed on a steering column and transfers effort on gear реечную transfer.
Gear рейка the steering mechanism from each party it is connected to cross-section steering draught by means of the spherical hinge. Steering draughts transfer force through steering tips and rotary fists to forward wheels. The reechnoe steering possesses an easy course and has no backlash at rotation of a steering wheel from an emphasis against the stop. The steering practically does not demand service, however it is necessary to check constantly a condition of protective covers of spherical hinges.
For simplification of turn of a steering wheel establish the hydraulic amplifier of a steering. It consists of the oil pump, a broad tank and маслопроводов. The pump put in action from the engine, through полиwedge a belt submits under pressure oil from a tank to the valve located in the steering mechanism. The valve is mechanically connected to steering shaft and submits oil depending on a direction of rotation of a steering wheel to the corresponding party of the working cylinder. Oil presses on the piston gear рейки and at the expense of it supports steering wheel movement. Simultaneously the piston pushes out oil on the other hand the working cylinder through the returnable pipeline back in a broad tank.
In the central part of a steering wheel the pillow of safety for the driver is established. The safety pillow from outside the driver enters into the standard equipment on all models.

In the presence of the lateral pillows of safety established in backs of forward seats, it is necessary to use only the covers recommended for forward seats.
Categorically it is forbidden to spend welding and рихтовочные works on details of system of a steering. At installation it is necessary to use new self-locking nuts.
Before removal of a pillow of safety execute the following:
– Switch off ignition and remove a wire of "weight" from the storage battery At removal of a wire of "weight" in car salon there should not be people;
– Isolate a wire connected to the negative plug of the storage battery to avoid of casual connection of a wire;
– Disconnect an one-contact electric socket for giving of pressure of a food to system of a pillow of safety;
