Back suspension bracket

Suspension bracket of back wheels

1 — a screw spring
2 — the stabilizer of cross stability
3 — differential
4 — a beam
5 — the shock-absorber

6 — a support
7 — the longitudinal lever
8 — the lower cross lever
9 — the top cross lever
10 — a brake disk

The BMW car of the 3rd series has an independent suspension bracket of each back wheel with the central lever. Each back wheel goes three levers: two cross and one longitudinal. Cross levers are connected with the longitudinal lever and a beam of an axis. The longitudinal lever is fixed by bolts through a rubber support in front to the body bottom. On a beam the differential is fixed. All elements of a back suspension bracket have the elastic and not demanding service rubber support that reduces transfer of the fluctuations resulting from influence of the road and the power unit by salon with passengers.

Podressorivaniye of the car is carried out by means of screw springs and shock-absorbers. Stability of the car on turns is carried out by the stabilizer of cross stability.

The torque from the engine and RKPP is transferred to back wheels via the driveshaft, differential and power shafts.

Carrying out welding and leveling works on elements of a back suspension bracket is not allowed. The self-stopped nuts, and also rusty bolts / nuts during repair are surely replaced with new.
