To change the direction of travel in the carSteering is provided. It consists of a rudder and a shaft that enters the mechanism connected to the trapezium. The last detail on most cars consists of a rail and outgoing from it to the wheels of long and short links with hinges.
Varieties
To simplify the rotation of the steering wheel on modern cars installed amplifier. It can be of different types:
1) Hydraulic.
2) Electrical.
3) Electrohydraulic.
The hydraulic amplifier works on the strength of the special fluid that the pump pumps.
Symptoms of control failure
With increased wear of the steering partsWhen the steering wheel is turned in place, a squeak is heard, and there are various kinds of foreign knocking that increase with time. They entail a malfunction or a complete refusal to work. Signs of a malfunction of this control include knocks in the steering mechanism, rail, tip or links. There is a scratch when turning the handlebar in place and extraneous noise in motion.
Squeak when turning without an amplifier
On cars "Dacia" and "Renault Logan" in the basethe presence of an amplifier is not provided. Therefore, squeaks when turning the helm in place (Logan 1.6 including) may occur due to breakdown of the front suspension spring, wear of the bearing of the upper support of the telescopic pillar, or due to the wear of the rubber pillow of the pillar support. With a strong wear, and especially when the development is uneven, it begins to squeeze out. Hence, a rubber squeal arises when the steering wheel is turned in place.
Sounds on the car with hydraulic booster
The steering gear with hydraulic booster consists of thosethe same details and trapezoids, only in the rail there are special oil channels. Through them oil under pressure acts on the steering rods, which facilitates the rotation of the wheels.
- wear of the impeller of the power-steering pump;
- wedging of the pump of the hydraulic booster;
- wear of the belt;
- pierced anthers in the steering rack (it will start to flow);
- wear of the drive pulley of the pump of the amplifier.
This trouble happens, even when the steeringmanagement is correct. In a strong reversal in place of the wheels, the load on the hydraulic pump becomes large. Especially when the car is loaded. Sound occurs due to increased wear of the drive pulley or belt.
Problems with the electric booster
Unlike steering with hydraulicdrive, the rotation of the wheels facilitates the electric motor. It is connected to the steering gear by a belt drive. On cars VAZ-2127 the control with the electric amplifier is established. Squeak when turning the steering wheel in place ("Priora" including) is possible for the following reasons:
- wear of the belt;
- wear of the pulley of the electric motor and steering gear;
- low voltage in the network;
- lack of "mass" of the car;
- malfunction of the electrical control unit.
Breakdowns
In addition to the wear of the pulley and the belt that connects the motor to the mechanism, it is also possible to creak when turning the handlebar in place because of a breakdown of the wire leading to the motor.
Eliminating extraneous sound
To eliminate the scratch when turning the steering wheel in place,first, you should determine the cause of extraneous sounds. On vehicles with power steering, a "check" will light up when the system is malfunctioning. Therefore, the driver should diagnose his car for errors. Special software at the service station will show where the disruption occurs and which sensor is out of order. When the cause is found, proceed to repair. If the problem is in the suspension, the damaged and worn out parts are replaced with new ones.
Service
For the steering to work properly,the driver should know how to properly maintain and operate it. To do this, carry out maintenance: replace the oil in the power steering pump, wear out the tips or steering rods, replace them with new ones, check the alignment of the wheels and, if the corners do not match, adjust them. Spare parts and oil must be from quality and original manufacturers. In the course of operation, the driver must monitor the condition of the steering, the operation of the hydraulic or electric amplifier.
Conclusion
Proceeding from this, it is necessary to emphasize thatthe correct operation of the steering depends primarily on the driver. From the way it serves the mechanism, it monitors its condition and exploits, its serviceability depends. Therefore, it is important to take care of the steering, take care of it for serviceability, handle it according to the maintenance book and repair it using only high-quality spare parts. Following these rules, the driver will ensure the long-term operation of the steering control of his car, which will give good control during the movement and its safety.
