Description of the steering design (Scorpio 2)

The steering system consists of a steering wheel, a steering shaft, a steering gear, and steering rods. The steering wheel is screwed to the steering shaft, which transmits the steering wheel movements to the steering gear. In the steering gear, a toothed rack moves in accordance with the rotation of the steering wheel.

Each toothed rack horse is connected to the steering rod via a ball joint. The steering rods transmit steering forces to the front wheels of the car via ball joints and pivot bearings.

The steering rack has a smooth movement and should move without play from stop to stop. It does not require maintenance, but the bellows should be checked for perfect condition as part of maintenance.

The steering of the wheels is made easier by the hydraulic power steering. The hydraulic power steering consists of an oil pump, a compensation tank with oil and pipes. The oil pump is driven by a V-belt from the engine crankshaft. The pump takes oil from the compensation tank and supplies it under high pressure to the valve located in the steering gear housing. The valve is connected to the steering column and directs the oil depending on the position of the steered wheels to the corresponding chamber of the working cylinder. It exerts little pressure on the piston of the toothed rack and thereby increases the force exerted by the driver on the steering wheel. At the same time, through the drain groove of the spool valve, the piston squeezes oil from the other chamber of the working cylinder into the return pipe and through it back to the oil tank. Depending on the model and equipment, steering of the wheels is made easier by the amplifier, the action of which depends on the speed of the vehicle (Servotronic system). Due to this, when turning the steering wheel of a stationary vehicle, the effort expended by the driver becomes less, and at high speed, on the contrary, as a result of reducing the amplifying effect of the amplifier, a better feeling for the road and high sensitivity of the vehicle to the turn of the steering wheel are achieved.



The driver's airbag is located in the steering wheel. In the event of a severe frontal collision, the control unit ignites a small pyrotechnic cartridge in the airbag unit, and the gases generated by the explosion inflate the airbag within a few milliseconds. This time is sufficient to dampen the impact of the driver rushing forward. The airbag then deflates within a few seconds, as the gases escape through the holes in the bag.

Safety instructions

Always replace the self-locking nuts. Welding and straightening work on steering components is not permitted. Work on the airbag system must be carried out at a service station, explosion hazard!
