7.1.1. Features of a design

Forward suspension bracket independent, telescopic, with hydraulic damping racks, twisted barrel-shaped springs, the lower cross levers with extensions and the stabilizer of cross stability.

Fig. 7.1. Forward suspension bracket assembled: 1 – nut of fastening of the top support of a rack; 2 – bolt; 3 – top support of a rack of a forward suspension bracket; 4 – bearing of the top support of a rack; 5 – the top isolating laying of a spring; 6 – spring of a forward suspension bracket; 7 – protection cover; 8 – telescopic rack assembled; 9, 10 – nuts of fastening are resistant to a rotary fist; 11 – a bolt with the clown; 12 – bolt; 13 – rotary fist; 14 – shaft of the drive of a forward wheel; 15 – stabilizer bar; 16 – lever; 17 – extension; 18 – spherical support; 19 – nave; 20 – nut of fastening of a nave; 21 – brake disk; 22 – buffer of the course of compression of a forward suspension bracket; 23 – top cup of a spring; 24 – limiter of the course of compression of the top support of a rack; 25 – limiter of the course of the top support of a rack

Basic element of a suspension bracket is the hydraulic telescopic damping rack of 8 (fig. 7.1) which lower part is connected to a rotary fist 13 two bolts 11 and 12. The top bolt 11 passing through an oval opening of an arm of a rack has an eccentric corbel and a washer. At turn of the top bolt disorder of a forward wheel changes.
On a telescopic rack the twisted barrel-shaped spring 6, the polyurethane foam buffer 22 courses of compression and the top support 3 racks assembled with the bearing 4 are established.
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 are mounted.
The lower part of a rotary fist is connected by a spherical support 18 to the lower lever 16 of a suspension bracket. Brake and traction forces are perceived by longitudinal extensions 17 which via rubber-metal hinges are connected to the lower levers and to forward support of a cross-piece of a forward suspension bracket. In extension junctions with the lever and a forward support adjusting washers which regulate a corner of a longitudinal inclination of an axis of turn are established.

Fig. 7.2. Rotary fist and details of a nave of a forward wheel: 1 – rotary fist; 2 – external mud-reflective ring; 3 – hug bearing; 4 – wheel nave; 5 – persistent washer; 6 – nut; 7 – lock rings; 8 – internal mud-reflective ring

In a rotary fist (fig. 7.2) the two-row radial-stop bearing 3 of the closed type on which internal rings the nave 4 wheels is established with a tightness fastens. The bearing will be tightened a nut 6 on a shaft of the case of the external hinge of the drive of wheels and it is not regulated. 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 15 (see fig. 7.1) which knee through racks with rubber and rubber-metal hinges are connected to the lower levers 16 of a suspension bracket. The middle (torsion) part of a bar fastens to a body arms through rubber pillows.
