Types of steering racks. Causes of the cookel rack

Progress is not standing on the spot, and the Worm Steering Steering Mechanism came to change, which quickly gained popularity in all world automakers. Compared to its predecessor, it has a smaller amount of component parts subject to wear, which has a positive effect on reliability. In addition, the car with such a steering mechanism has a more acute control, which means improved driving safety and many positive emotions at the driver.

The service life of the steering rail (with regular maintenance) is about 100,000 km of mileage. Over time, as wear, malfunctions will appear, including the most common - knock in the steering rake. Troubleshooting better entrust to the service center, but you can determine the cause yourself. But before we tell you how to draw diagnostics with your own hands, let's consider the structure of this mechanism in more detail, and why the steering rail is knocking.

Of what's from st ooo t p ul eva i rake

The simplest mechanical steering rail has the following construction: a corrugated case is mounted in a special form crankcase; There, on several bearings, there is a steering shaft gear, driven by a wheel through the shaft, and with the help of a spring, a toothed rack is pressed (the spring is needed, so that there is no gap between the gear and rack).

Currently, the greatest popularity has gained 3 types of steering wheels. Their main difference from each other is how the mechanism itself works.

Types of steering areas

• Mechanical steering rack

The simplest and reliable. The wheels turn only at the expense of physical strength. For larger comfort, the driver often happens with a different step of the rack's teeth from the edge to the middle (it reduces the effort on the steering wheel at a low speed).

• Hydraulic steering rack

Such a rail is equipped with a hydraulic cylinder (GUR), as a result of which the sharpness and ease of control of the car increases. In addition, when traveling through a bad road, the steering wheel does not break away from the hands, unlike the mechanical rail. Most machines manufactured in the world are equipped with this particular steering mechanism.

• Electric steering rack

It is very similar to a hydraulic, but an electric motor, controlled by the ECU, is used as an amplifier. It is used mainly on business class cars and sports cars for which excellent handling. On budgetary machines is rarely established.

Cause n.s knock but RU l.eV aboutth racks

The causes of the appearance of the knock in the steering rake can be:

• Weed fastening connections.
• Wear a support sleeve.
• Handling formation in bearings.
• Wear of the teeth of the rail.
• Movered tear comes into contact with the wheel rack housing due to wear of the antifriction lining.

You can conduct diagnostics to a hundred or do it on your own. In the second case, the sequence of actions will be as follows:

1. Find the assistant to help you. It is impossible to inspect the rail;
2. Make sure the motor does not work, put the machine to the "handbrack" and ask the assistant to go to the driver's seat;
3. Climb under the car and find the steering rack, then tell the assistant to twist the steering wheel left-right;
4. If the rake from the GUR, appreciate the condition of the hoses for leaks. Also check the fluid level and its transparency;
5. Check if anthers are damaged, and whether there is no lubricant herdes somewhere;
6. If, according to the total of the two previous points there are no complaints, listen, where the knock comes from. Most likely, the case in bearings or wear of the rails of the rail. The steering rail will have to shoot and sort out, or even change the whole;
7. Now you can proceed to repair the damaged node on your own or go to the car service.

Both t. t. Rule ini will rake from n Olomki

1. Do not twist, steering steering wheel - leave a small stroke stock.
2. Carefully move in bad roads. Wheels in the pit at high speed can damage the steering rack.
3. If the car is equipped with GUR, follow the liquid in it, and more specifically for its level and color. Also do not forget to change the liquid on time.
4. Control the state of anthers. If there are doubts about their tightness - immediately change.

How much is the repair of the steering rack?

Steering rack cost for VAZ - About $ 130. For foreign production machines, rates are noticeably more: from 200 to $ 500. Such prices are valid for steering wheels without concomitant components: GUR and tips with tips. Steering rack assembly is much more expensive: for VAZ from $ 230, and for foreign cars From $ 1000 and more (depending on the class of the car).

If you do not change the steering rack on your own, and contact the car service, then the cost of the specialists will have to add to the amounts.
