4.3.19. Check of a technical condition of details of a forward suspension bracket on the car

All checks and works carry out from below the car established on the lift or a viewing ditch (with the hung-out forward wheels).

At each maintenance and repair it is necessary to check a condition of protective covers of spherical support of a suspension bracket, on covers there should not be mechanical damages.

Find out, whether there is no on details of a suspension bracket of cracks or zadevaniye traces about road obstacles or a body, a deformation of levers, bars of the stabilizer and its racks, details of a front of a body in places of fastening of knots and suspension bracket details.

Check a condition of rezinometallichesky hinges, rubber pillows, spherical hinges of a suspension bracket, and also a condition (deposit) of the top support of telescopic racks of a suspension bracket.

Rezinometallichesky hinges and rubber pillows are subject to replacement at gaps and a unilateral vypuchivaniye of rubber, and also when cutting their face surfaces.

Fig. 4.2. An arrangement of elements of a forward suspension bracket on the car: 1–forward hinge (saylentblok) of the lever of a forward suspension bracket; 2–spring of a forward suspension bracket; 3–amortizatorny rack of a forward suspension bracket; 4–spherical support; 5–hinge of the stabilizer of cross-section stability; 6–bar of the stabilizer of cross-section stability; 7–back hinge (saylentblok) of the lever of a forward suspension bracket; 8–stretcher

The arrangement of elements of a forward suspension bracket on the car is shown on fig. 4.2.

On rubber details of a suspension bracket are not allowed:

– signs of aging of rubber;

– mechanical damages.

On rezinometallichesky hinges are not allowed:

– signs of aging, crack, unilateral vypuchivaniye of the rubber massif;

– a separation of the rubber massif from fittings.

Faulty details replace.

Prevention Special attention turn on mechanical damages (deformations, cracks, etc.) suspension bracket elements, especially levers.

1. Check a condition of protective covers of spherical support. If covers are damaged, replace spherical support assembled.	2. Shaking a wheel in the vertical plane, check spherical support on existence люфтов. If is люфты spherical fingers, replace support.

Good advice When rocking the hung-out forward wheel it is difficult to distinguish люфты in bearings of naves and in spherical support. Ask the assistant to press a brake pedal: if in this case will feel люфт, spherical support are faulty.

3. Check on absence люфта lobbies...	4.... and back сайлентблоки in places of fastening of levers to a stretcher.

5. Check a condition of rubber pillows in places of fastening of racks of the stabilizer of cross-section stability to the suspension bracket lever...	6.... and a condition of plugs in a place of fastening of a bar of the stabilizer to a rack.

7. Check a condition of rubber pillows in places of fastening of a bar of the stabilizer of cross-section stability to a stretcher.

8. Check a condition of a protective casing of an amortizatorny rack.

9. Lift a protective cover and check the shock-absorber on tightness. Begin to flow liquids are not allowed.

10. The faulty or damaged details replace.
