Suspension bracket of back wheels and the back bridge

THE GENERAL DATA

There are two variants of a design of a back suspension bracket for Frontera. The car to the middle of 1995 of release has a rigid axis on flat springs and hydraulic shock-absorbers. On later models the back suspension bracket with four cross-section levers and screw springs and газонаполненными shock-absorbers has been entered.
The description of old model of a suspension bracket here is not resulted. The description of the new suspension bracket having more difficult design is more low given.

Longitudinal levers of a suspension bracket are executed from pipes. Short, located in the centre over картером differential the lever, serves for perception of the loadings arising in the course of braking and dispersal. Lateral fastening is carried out by means of draught of the cross-section lever, the so-called cross-section jet bar fixed by one end behind on the right to the bridge, and other end at the left to the chassis.
The suspension bracket has the stabilizer of cross-section stability established on rubber plugs in front of the bridge and connected with the bridge by connecting bars with spherical hinges.

Levers and cross-section jet bar have the rubber plugs possessing the minimum friction that provides free moving of a suspension bracket at car arrival on various roughnesses of road. The bridge and a suspension bracket are shown on an illustration.

The back bridge with screw springs of a suspension bracket



Two are applied to a drive of the back bridge various карданных a shaft. At three-door cars карданный a shaft whole. At cars with the increased base (5 doors) it is applied карданный a shaft, two-piece, having an intermediate support.
Besides, there is a difference in a design of the back brake mechanism. Drum-type and disk brakes that influences performance of some works are applied.

At performance of repair work it is necessary to take into consideration distinction in a design of a back suspension bracket. If in the text there are no corresponding instructions, works for both executions of a suspension bracket are carried out equally.

At performance of works on a back suspension bracket it is necessary to be guided by the instructions resulted in the beginning of section "Suspension bracket of forward wheels". It is not necessary to forget about necessity of reliable fastening of the car.
