Basic element of a suspension bracket is the telescopic, hydraulic damping rack of 9 (fig. 4.1) which lower part connects to a rotary fist 13 two bolts. The top bolt 11 passing through an oval opening of an arm of a rack has an eccentric corbel and an eccentric washer 10. At turn of the top bolt disorder of forward wheels changes.
On a telescopic rack are established: a twisted cylindrical spring 5, the polyurethane foam buffer 3 courses of compression, and also the top support of 1 rack assembled with the bearing 38.

Fig. 4.2. Telescopic rack: 1 – compression valve case; 2 – compression valve disks; 3 – throttle disk of the valve of compression; 4 – plate of the compression valve; 5 – compression valve spring; 6 – compression valve holder; 7 – return valve nut; 8 – return valve spring; 9 – plate of the return valve; 10 – return valve disk; 11 – throttle disk of the valve of return; 12 – piston; 13 – plate of the perepuskny valve; 14 – spring of the perepuskny valve; 15 – plunger; 16 – plunger spring; 17 – the directing rod plug with a ftoroplastovy layer; 18 – a holder of the directing plug; 19 – sealing ring of the case of a rack; 20 – rod epiploon; 21 – epiploon holder; 22 – laying of a protective ring of a rod; 23 – protective ring of a rod; 24 – rack case nut; 25 – compression buffer support; 26 – rod; 27 – spring cup; 28 – rotary lever; 29 – restrictive plug of a rod; 30 – rack case; 31 – cylinder; 32 – drain tube

The top support fastens three самоконтрящимися nuts to a body mudguard rack. Due to the elasticity the support provides "swing" of a rack at the courses of a suspension bracket and extinguishes high-frequency vibrations. The bearing which is built in in it gives the chance to a rack to turn together with the operated wheels. In the case of a rack details of the telescopic hydraulic shock-absorber shown in fig. 4.2 are mounted.
In the top part of the cylinder the hydraulic buffer of the course of return consisting of a plunger 15 and springs 16 is installed. It limits movement of a rod at the return course.
The lower part of a rotary fist 13 (see fig. 4.1) connects the spherical hinge 21 to the cross lever 22 suspension brackets. Brake and traction forces are perceived by longitudinal extensions 29 which via rubber-metal hinges connect to cross levers 22 and to arms 30. In extension junctions with the lever and an arm adjusting washers 23 which regulate a corner of a longitudinal inclination of an axis of turn are established.
In a rotary fist the two-row radial-stop bearing 20 of the closed type on which internal rings the wheel nave is established with a tightness fastens. The bearing drags on a nut 17 on a shaft of the 18th case of the external hinge of the drive of wheels and is not adjusted. All nuts of fastening of forward and back naves of wheels identical also have the right carving.
The stabilizer of cross stability represents a bar 25 which knee through drains 24 with rubber and rubber-metal hinges 22 suspension brackets are connected to cross levers. The middle (torsion) part of a bar fastens to a body arms 27 through rubber pillows.
