9.0 Rear suspension parts
1 - bearing beam of the rear axle
2 - upper trailing arm
3 - coil spring
4 - brake drum
5 - lower trailing arm
6 - shock absorber
7 - torsion stabilizer bar
The rear axle with trailing arms of the independent suspension of A-class vehicles is formed by a steel transverse beam made of a pipe to which the upper trailing arms are welded. A stabilizer bar is located in front of the pipe, which compensates for the tilt of the body when cornering, and also prevents the rear wheel from lifting inside the turning radius.
The damping of the body is carried out by two helical springs located between the longitudinal arms. In front of the springs are single-tube gas-filled shock absorbers. Due to the compact design of the bridge, in which the springs and shock absorbers are placed under the trailing arms, the internal volume of the cabin has not decreased (see illustration 9.0).
The rear axle is maintenance free.
