Steering The general information The steering consists of a steering wheel, a steering spindle, zubchato-reechnogo the steering mechanism and a steering drive. The steering wheel has carving fastening on a spindle which transfers operating movements to the steering mechanism. For simplification of driving at a parking there is a wheel hydraulic booster. The factor of strengthening of a steering drive depends on number of turns of the engine. At high turns the strengthening factor decreases, at low turns raises. Some models of the car have the hydraulic booster which factor of strengthening depends on speed movements (system Servotronic). Thanks to it the effort put to a steering wheel decreases on the standing car. At high speed of movement the factor of strengthening of a wheel that provides the best contact to road and more a management split-hair accuracy decreases. The hydraulic booster consists of the oil pump, the tank of oil and маслопроводов. The oil pump is set in motion клиновым by a belt. The pump soaks up oil from the tank and submits it under pressure to the steering mechanism where the adjusting element of the hydraulic booster settles down. The pillow of safety of the driver is located in a steering wheel. In case of a strong head-on collision the management block ignites a small charge in an air cushion. Gases formed thus inflate a pillow of safety during several milliseconds. It is enough this time to amortise sharp moving forward the top part of a trunk. Then within several seconds the pillow is blown off, since. Gases leave through apertures in a pillow. On safety conditions of work with system of a pillow of safety it is necessary to make in firm BMW repair trucks.
