Back suspension bracket Back suspension bracket in gathering
1 – the shock-absorber
2 – a screw spring
3 – a beam of a back suspension bracket
4 – the top support of a spring
5 – a shock-absorber support
6 – the compression buffer | 7 – a brake disk
8 – the wheel bearing
9 – the stabilizer of cross-section stability
10 – резинометаллический the bearing
11 – a cable of a lay brake |
Elements of a back suspension bracket. Models with a forward drive
ATTENTION
In the presence of damage hydraulic резинометаллической support – 13 it is necessary to replace in the complete set a beam – 14 (work HUNDRED).
1 – a brake disk
2 – двенадцатигранная a nut with a fillet, 175 Н•м. Self-stopped, necessarily replace.
3 – a cap. Necessarily replace. Since 4/97 releases, caps have a covering a tight varnish of green colour. Earlier caps should be inserted on hermetic.
4 – the screw with crosswise шлицем, 4 Н•м
5 – a bolt of fastening of a wheel, 120 Н•м
6 – a nave with the wheel bearing
7 – a bolt, 60 Н•м
8 – a pin
9 – a bolt. Necessarily replace.
10 – a bolt, 30 Н•м + 90 ° (1/4 turns). Necessarily replace.
11 – a support. For removal of a back suspension bracket whenever possible do not turn on. If the support was disconnected, it is necessary to regulate disorder.
12 – a nut, 80 Н•м. Necessarily replace. Load a luggage carrier of the car with cargo of 100 kg and tighten a nut on the car standing on wheels. | 13 – a support резинометаллическая or hydraulic резинометаллическая a support
14 – a suspension bracket beam
15 – the top basic ring rubber
16 – a spring screw
17 – a zinc lining
18 – a bolt, 60 Н•м. Necessarily replace.
19 – the shock-absorber
20 – a bolt, 30 Н•м + 90 ° (1/4 turns). Necessarily replace.
21 – the screw with internal шестигранником, 8 Н•м
22 – gauge ABS
23 – a nut. Necessarily replace.
24 – a guard
25 – the screw with internal шестигранником, 65 Н•м. Necessarily replace.
26 – a support |
The back suspension bracket consists of two longitudinal levers with a connecting beam. Before a beam V - a figurative profile there is a stabilizer of cross-section stability which reduces a car inclination on turns and, thereby, stabilises its position. The back suspension bracket through резинометаллические support is connected with a body. Car amortisation is carried out by two screw springs and two shock-absorbers. Springs and shock-absorbers are located separately that increases width of cargo volume.
Dual ball-bearings of back wheels do not demand leaving and adjustment.
Cars with a full drive have an independent back suspension bracket with dual cross-section levers and longitudinal balance weights.
For twisting moment transfer the shaft, the main transfer and two power shafts are established карданный.
Measurement of geometry of a back suspension bracket probably only with application of optical methods.
ATTENTION Carrying out welding and рихтовочных works on bearing and directing elements of a back suspension bracket is not supposed. Self-stopped nuts, and also bolts/nuts with corrosion traces necessarily replace.
