Forward suspension bracket Forward suspension bracket in gathering
1 – a support of an amortisation rack
2 – an amortisation rack
3 – the case of bearings of wheels
4 – the hinge of a power shaft of a wheel
5 – tightening a bolt
6 – the cross-section lever | 7 – a unit beam
8 – power shafts
9 – the stabilizer of cross-section stability
10 – connecting draught plastic
11 – the steering mechanism
12 – steering draught | Elements of a forward suspension bracket
1 – a nut with a fillet, 60 Н•м
Necessarily replace
2 – a cup
3 – a body
4 – an amortisation rack
5 – the case of the wheel bearing
6 – шестигранная a nut
7 – a spherical support. Position mark. At replacement of the lever of a suspension bracket establish on the middle of an oval aperture and check up a track (work HUNDRED).
8 – a nut, 45 Н•м
Self-stopped, it is necessary to replace necessarily.
9 – bolts, 20 Н•м + 90 ° (1/4 turns)
Self-stopped, are necessarily replaced.
10 – a plate with a nut
11 – the cross-section lever
12 – a drive shaft
13 – the combined bolt, 70 Н•м + 90 ° (1/4 turns). Self-stopped, are necessarily replaced.
14 – a bolt, 100 Н•м + 90 ° (1/4 turns). The carving in a body can be repaired by means of a carving insert Heli - Coil. The length of a carving of a repair insert should be equal to length of a carving in a body.
15 – steering draught
15 – a connecting bar. It is made of plastic. | 17 – a bolt, 45 Н•м
18 – the combined bolt, 100 Н•м + 90 ° (1/4 turns). Self-stopped, it is necessary to replace necessarily. The separator nut cannot be processed. In the presence of damages on a nut it is necessary to replace a support in the complete set.
19 – a nut, 30 Н•м. Self-stopped, it is necessary to replace necessarily.
20 – the stabilizer. For removal and installation it is necessary to lower a unit beam.
21 – a bolt, 70 Н•м + 90 ° (1/4 turns)
22 – a unit beam
23 – a nut. Self-stopped, it is necessary to replace necessarily.
24 – резинометаллическая a support
25 – bolts cylindrical, 40 Н•м.
М8 х 47.
26 – a lining
27 – a shaft with the hinge of equal angular speeds
28 – bolts cylindrical, 40 Н•м.
М8 х 18.
29 – a stabilizer collar
30 – a bolt, 25 Н•м
31 – hinge Tripode
32 – a support rubber |
Forward suspension bracket – independent. Amortisation racks of a suspension bracket includes a screw spring and the shock-absorber. Both amortisation racks are connected болтовыми by connections with a body and cases of wheel bearings. Cases of wheel bearings cope through the triangular levers connected with a beam of the unit. The unit beam is connected болтовыми by connections with the car bottom.
Transfer of a twisting moment from the engine on wheels is carried out through two power shafts which by means of two hinges of equal angular speeds are connected with wheels and the main transfer.
Correct installation of wheels is necessary for achievement of optimum road qualities and the minimum deterioration of tyres. At excessive deterioration of tyres, and also bad stability on road should address on HUNDRED where the optical control of installation of wheels can be made. Measurement of a running gear without application of corresponding optical methods is impossible.
ATTENTION Performance welding and рихтовочных works on bearing and directing wheels of the car design elements is not supposed. Self-stopped nuts and the bolts/nuts having corrosion, in case of repair are replaced with the new.
