The steering system consists of a steering wheel, a steering shaft, a steering gear, a tie rod, a steering damper and a power steering booster. The steering wheel is screwed to the steering shaft, which transmits the rotation of the wheel to the steering mechanism.
Depending on the position of the steering wheel, the gear in the steering mechanism changes. This means that the more you turn the steering wheel, the more indirect the transmission becomes. The steering wheel thus, for example, at a parking, turns easier. Direct transmission in the middle position provides increased control accuracy, especially at high speeds.
The hydraulic booster provides a small effort on the steering wheel. It consists of a pump, reservoir and pipes. The pump draws hydraulic oil from the reservoir and delivers it under pressure to the steering gear, where the adjusting device and the slave cylinder provide adequate reinforcement.
As an option, a mechanical steering column length adjuster can be installed to install the steering wheel.
While the driver's airbag is integrated into the steering wheel, the passenger's airbag is on the right side of the dash. With a strong frontal impact, a squib is triggered, and the pillows inflate in thousandths of a second. This time is enough to soften the frontal impact for people. Within seconds of being deployed, the airbag deflates as gases escape through holes in it. An inflatable pillow for the passenger is installed as an additional equipment.
The company recommends replacing the airbag after ten years of vehicle use to ensure its performance.
Attention! Self-locking nuts are always replaced. Welding and straightening work on the steering is unacceptable. With a lack of experience, as well as large repairs, you should contact the workshop.
Instructions for handling the airbag
The device cannot be disassembled; in case of a malfunction, everything is replaced as an assembly. Because the block contains explosives, keep it locked or supervised. Recycling is carried out by company workshops.
After disassembly, hold the unit with the soft side up.
The cushion unit must not be cleaned with water or cleaning agents.
Do not overheat the unit above 100°C.
The airbag unit is impact sensitive. If it fell from a height of 50 cm, then it can no longer be placed on a car.
The airbag unit may only be removed when the battery ground terminal is disconnected (–) and in position "ABOUT" ignition key.
