Suspension bracket of back wheels and back bridge

GENERAL INFORMATION

There are two options 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 gas-filled shock-absorbers was entered.
The description of old model of a suspension bracket here is not provided. The description of the new suspension bracket having more difficult design below is given.

Longitudinal levers of a suspension bracket are executed from pipes. Short, located in the center over a differential case the lever, serves for perception of the loadings arising in the course of braking and dispersal. Lateral fastening is carried out by means of draft 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 before 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 the road. The bridge and a suspension bracket are shown on an illustration.

Two various driveshafts are applied to a drive of the back bridge. At three-door cars the driveshaft whole. At cars with the increased base (5 doors) the driveshaft, two-piece, having an intermediate support is applied.
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 works on a back suspension bracket it is necessary to be guided by the instructions provided in the beginning of the section "Suspension bracket of forward wheels". It is worth to remember about need of reliable fixing of the car.
