20.1. General information
Steering consists of a steering wheel, a steering column, the mechanism of steering and cross steering drafts. For convenience of driving adjustment of a steering wheel on height is provided.
The steering wheel is fixed on a steering column and transfers effort to tooth rack gearing.
The gear lath of the steering mechanism from each party is connected to cross steering draft by means of the spherical hinge. Steering drafts transmit force through steering rod ends and rotary fists on forward wheels. Rack steering possesses the easy course and has no side play at rotation of a steering wheel from an emphasis against the stop. 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 steering. It consists of the oil pump, a broad tank and oil pipelines. The pump put in action from the engine through poliklinovy a belt gives under pressure oil from a tank to the valve located in the steering mechanism. The valve is mechanically connected to a steering shaft and gives oil depending on the direction of rotation of a steering wheel to the relevant party of the working cylinder. Oil presses on the piston of a gear lath and at the expense of it supports the movement of a steering wheel. At the same time the piston pushes out oil on the other side of the working cylinder via the returnable pipeline back in a broad tank.
In the central part of a steering wheel the safety cushion for the driver is established. The safety cushion from the driver enters the standard equipment on all models. The security system is put in action at inclusion of ignition and becomes more active the delay sensor which is switched on in the control unit. With malfunction in system of a safety cushion in a combination of devices the control lamp lights up.
When performing any works on the car equipped with a safety cushion during the moving and storage of a pillow it is necessary to observe the following precautions:
– not to disconnect the rechargeable battery at the working engine;
– not to disconnect the plug of the rechargeable battery when in interior of the car there are people;
– when performing any works on a security system or carrying out electric welding on the car deactivate a security system;
– if the control lamp of the alarm system of a security system burns, it is necessary to address immediately on service station;
– it is necessary to transport a safety cushion separately, a bag up;
– when transporting not to put a hand on a safety cushion;
– not to throw and not to sort a safety cushion;
– to exclude hit on a safety cushion of solvents or the clearing substances;
– not to subject a safety cushion to influence of temperature over 80 °C;
– not to allow contact of a safety cushion with an open flame;
– not to install on the car a safety cushion with defects or damages.
In the presence of the side safety cushions established in backs of front seats it is necessary to use only the covers recommended for front seats.
It is strictly forbidden to carry out welding and leveling works on details of system of steering. At installation it is necessary to use new самоконтрящиеся nuts.
Before removal of a safety cushion execute the following:
– switch off ignition and remove a wire of "weight" from the rechargeable battery At removal of a wire of "weight" in interior of the car there should not be people;
– isolate the wire connected to the negative plug of the rechargeable battery to avoid casual connection of a wire;
– disconnect the one-contact electric socket for giving of supply voltage to system of a safety cushion;
– establish forward wheels for the movement directly forward.
Non-compliance with these requirements can lead to failure of system of a safety cushion.
