10. Suspension bracket and steering

GENERAL INFORMATION

Elements of a forward suspension bracket

1. Stabilizer of cross stability
2. Stabilizer plug clip
3. Suspension bracket lever
4. Spherical hinge
5. Suspension bracket rack with a spring

6. Right half shaft
7. Left half shaft
8. Rack 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 lower end of a rack fastens to a rotary fist. The rotary fist also fastens to the spherical hinge installed on the external end of the lever of a suspension bracket. The stabilizer of cross stability reduces fluctuations of a body of the car.

Elements of a back suspension bracket


1. Cross draft of N2 (back)
2. Draft length regulator
3. Cross draft of N1 (forward)
4. Stabilizer of cross stability of a back suspension bracket
5. Stabilizer plug clip

6. Connecting draft of the stabilizer
7. Longitudinal draft
8. 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 lower end of a rack fastens to a nave arm. The arm fastens to two cross 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 rack 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 need to be checked periodically for reliability of fastening, existence of gaps or leak of greasing.

The system of strengthening of a steering consists of the pump with the drive from a driving belt of the engine and includes tubes and hoses. Level of hydraulic liquid in a tank of the pump needs to be checked 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 steering drafts or weakening of an inhaling of fixing bolts.

Precautionary measures

Often, during the work with elements of a suspension bracket or a steering, it is necessary to face threaded connections which, apparently, cannot be turned off. These connections under the car bottom constantly are affected by moisture, dust, dirt, etc. and can rust or stop and then it is very difficult to turn off them. 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 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 chisel can destroy the communication disturbing to work between a nut and a bolt be however accurate and do not damage a carving. Sometimes happens it is useful to heat the jammed connection by means of a blowtorch, however be extremely careful during the work with an open flame. Try to take a key with longer handle or to use a pipe piece which needs to be put on a key, having increased, thus, a shoulder. Sometimes before untwisting it is possible to try to put even more strongly the clamp or a bolt after that it can easier be turned off. Those bolts and nuts which were very heavy to be turned off, need to be replaced.

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


Prevention

It is forbidden to use a jack in quality
support. After untwisting and removal of bolts or nuts of threaded connections they need to be examined and if it is necessary, to replace new. Twist threaded connections till the demanded inhaling moment. Do not try to cook and level any of elements a suspension bracket or a steering. Replace the deformed or damaged elements new.
