Unregulated steering column
Steering consists of a steering wheel, a steering shaft, the steering mechanism, steering draft, the steering shock-absorber and the power steering. The steering wheel is screwed on a steering shaft which transfers rotation of a wheel to the steering mechanism.
Depending on the provision of a wheel transfer in the steering mechanism changes. It means that than the turn of a wheel is more, especially indirect is a transfer. The steering wheel at the same time, for example, at the parking, turns easier. Direct transfer on average situation provides the increased accuracy of management, in particular at high speeds.
The hydraulic booster provides small effort on a steering wheel. It consists of the pump, the tank and tubes. The pump soaks up oil for hydraulics from the tank and gives it under pressure to the steering mechanism where the control device and the working cylinder provide the corresponding strengthening.
As the additional equipment the mechanical regulator of length of a steering column for installation of a steering wheel can be put.
While the inflatable safety cushion for the driver is built in a steering wheel, the pillow for the passenger is on the right on the forward panel. At strong front blow the pyro works, and pillows are inflated for thousand fractions of a second. This time is enough to soften front blow for people. For only a few seconds after operation the pillow is blown off as gases come out through openings in it. The inflatable pillow for the passenger is put as the additional equipment.
The firm recommends to replace an inflatable pillow after ten years' operation of the car to guarantee its work.
Самоконтрящиеся nuts are replaced always. Welding and leveling works on steering are inadmissible. At a lack of experience, and also big repairs it is necessary to address in a workshop.
