Forward suspension bracket

General information

Forward suspension bracket

1 — a depreciation rack
2 — a screw spring
3 — the gas-filled shock-absorber
4 — the stabilizer cross
stability
5 — a stabilizer bar

6 — steering draft
7 — a beam of a forward suspension bracket
8 — the steering mechanism
9 — draft
10 — the lever of a cross suspension bracket

The independent suspension bracket of forward wheels on double levers, aluminum, has the beam connected with a body through rubber support. The forward beam via cross levers and drafts is connected with rotary support. The hydraulic opiraniye of cross levers provides compensation of fluctuations even at not balanced wheels. The depreciation racks connected with a body and rotary levers bolts consist of a screw spring and the gas-filled shock-absorber in the form of a double pipe. The stabilizer of cross stability counteracts a body inclination on turns and promotes the best contact of forward wheels with the road.

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

As the suspension bracket is made completely of aluminum, it is necessary to observe the following:

   a) The contact of a suspension bracket with electrolyte of the rechargeable battery is not allowed.
   b) It is necessary to apply to cleaning of a suspension bracket only a brush from stainless steel. It is impossible to apply brushes from steel or brass.
   c) At grinding/cutting elements of a suspension bracket need to be closed for protection against hit of sparks. To subject them to influence of a stream of sparks it is not allowed.
   d) Do not subject elements to a suspension bracket to influence of welding sparks. Close suspension bracket elements.
   e) Do not subject suspension bracket elements to influence with the temperature above + 80 °C. Influence of temperature of the painting camera is admissible.
