Forward suspension bracket

Suspension bracket of forward wheels

1 — a support
2 — a screw spring
3 — the shock-absorber
4 — a rotary fist
5 — a kachatelny 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 draft
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 gas-filled shock-absorbers, and also the stabilizer of cross-section stability.

Both amortization racks are connected with a body and rotary fists bolts. Rotary fists go cross-section levers from aluminum 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 increases coupling of forward wheels with the road.

The forward suspension bracket does not demand leaving.

Carrying out welding and leveling works on a forward suspension bracket is not allowed.

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

1 do not allow contact of aluminum details of a running gear to electrolit of the storage battery.
2 To cleaning apply only brushes from stainless steel. Do not apply a brush from carbonaceous steel and brass.
3 When polishing / разрезке around close aluminum details of a running gear, do not subject to their influence of sparks.
4 do not subject to influence of steel welding splashes, close aluminum details.
5 do not subject aluminum details to dot influence of temperature above +90°С. Coloring in chambers is allowed.
