Forward suspension bracket

Suspension bracket of forward wheels

1 — a support
2 — a screw spring
3 — the shock-absorber
4 — a rotary fist
5 — качательная a support
6 — the cross-section lever
7 — the holder of the cross-section lever

8 — a beam of a forward suspension bracket
9 — the steering mechanism
10 — the stabilizer of cross-section stability
11 — steering draught
12 — a brake disk
13 — a support

The independent suspension bracket of forward wheels consists of cross-section levers, MacPherson's racks with screw springs and telescopic газонаполненными shock-absorbers, and also the stabilizer of cross-section stability.

Both amortisation racks are connected with a body and rotary fists bolts. Rotary fists go cross-section levers from aluminium which are connected with a beam of a forward suspension bracket. The beam through hydrosupport is connected by bolts with the car bottom.

The forward suspension bracket has the stabilizer of cross-section stability which interferes on turns with an inclination of a body and raises coupling of forward wheels with road.

The forward suspension bracket does not demand leaving.

Carrying out welding and рихтовочных works on a forward suspension bracket is not supposed.

Considering that cross-section levers and support are executed completely from aluminium:

1 do not suppose contact of aluminium details of a running gear to electrolit of the storage battery.
2 To clearing apply only brushes from stainless steel. Do not apply a brush from a carbonaceous steel and a brass.
3 At polishing/razrezke by circle close aluminium details of a running gear, do not subject to their influence of sparks.
4 do not subject to influence of steel welding splashes, close aluminium details.
5 do not subject aluminium details to dot influence of temperature above +90С. Colouring in chambers is supposed.
