10. Suspension bracket and steering


Elements of a forward suspension bracket

1. Stabilizer of cross-section stability
2. Clip of the plug of the stabilizer
3. Suspension bracket lever
4. Spherical hinge
5. A suspension bracket rack with a spring

6. Right semi-axis
7. Left semi-axis
8. Reechny steering transfer
9. Cross-piece of fastening of the engine
10. Suspension bracket cross-piece

The forward suspension bracket uses MacPherson racks. From above each rack with a spring of a suspension bracket fastens to a support to a rack which in turn fastens to a body. The bottom end of a rack fastens to a rotary fist. The rotary fist also fastens to the spherical hinge established on the external end of the lever of a suspension bracket. The stabilizer of cross-section stability reduces fluctuations of a body of the car.

Elements of a back suspension bracket

1. Cross-section draft of N2 (back)
2. Regulator of length of draft
3. Cross-section draft of N1 (forward)
4. Stabilizer of cross-section stability of a back suspension bracket
5. Clip of the plug of the stabilizer

6. Connecting draft of the stabilizer
7. Longitudinal draft
8. A suspension bracket rack with a spring
9. Arm of a nave of a back wheel
10. Cross-piece of a back suspension bracket

The back suspension bracket also uses racks with springs. The top end of a rack fastens to a car body. The bottom end of a rack fastens to a nave arm. The arm fastens to two cross-section drafts of a suspension bracket, and for fastening the longitudinal draft of a suspension bracket established between an arm of a nave and a body serves in the longitudinal direction.

Steering transfer of reechny type is established behind an engine / box
transfers on a body partition also operates steering drafts, which
fasten to rotary fists. The internal ends of steering drafts are protected by rubber covers which are necessary for checking periodically on reliability of fastening, existence of gaps or leakage of greasing.

The system of strengthening of a steering consists of the pump with a drive from a driving belt of the engine and includes tubes and hoses. Level of hydraulic liquid in a tank of the pump is necessary for checking periodically (see subsection 2.5).

The steering wheel rotates a shaft of a steering column which operates steering transfer via the Universal hinge. Looseness of a steering can be caused by wear of the Universal hinge of a shaft of a steering column, wear of steering transfer, fastenings of cross-section steering drafts or weakening of an inhaling of fixing bolts.

Precautionary measures

Often, at work with suspension bracket or steering elements, it is necessary to face carving connections which, apparently, cannot be turned off. These connections under the car bottom constantly are exposed to influence of moisture, a dust, dirt etc. and can rust or stop and they are very difficult for turning off then. To solve this problem, without having broken sides of bolts or nuts (and without having damaged other elements) use a large amount of oil with the increased penetration and wait some minutes, having allowed it to be absorbed properly. Cleaning of a visible part of a carving by means of a wire brush also to allow it is easier to turn off a bolt or a nut. Sometimes, the strong blow of a hammer or a chisel can destroy communication stirring to work between a nut and a bolt be however accurate and do not damage a carving. Sometimes happens it is useful to heat up jammed connection by means of a blowtorch, however be extremely careful at work with an open flame. Try to take a natural longer handle or to use a piece of a pipe which is necessary for putting on a key, having increased, thus, a shoulder. Sometimes before untwisting it is possible to try to twirl even more strongly a nut or a bolt after that it can easier be turned off. Those bolts and nuts which needed to be turned off, it is necessary to replace.

As the majority of the operations described in this chapter, the poddomkrachivaniye of the car and work under its bottom demand, it is necessary to get pair of good support. For lifting of the car it is recommended to use a hydraulic jack. It can be used for maintenance of some elements and car units at performance of various operations.


It is forbidden to use a jack in quality
support. After untwisting and removal of bolts or nuts of carving connections they are necessary for examining and if it is necessary to replace new. Twist carving connections till the demanded moment of an inhaling. Do not try to cook and level suspension brackets any of elements or a steering. Replace the deformed or damaged elements new.
