Forward suspension bracket (left side): 1–spring of a forward suspension bracket; 2–bottom plate of a spring; 3–telescopic shock-absorber; 4–rotary fist; 5–spherical support; 6–rack of the stabilizer of cross-section stability; 7–lever of a forward suspension bracket; 8–plug of a back support of the lever; 9–bracket of fastening of a bar of the stabilizer of cross-section stability; 10-saylentblok of the lever of a forward suspension bracket; 11-bar of the stabilizer of cross-section stability; 12-cross-piece of a forward suspension bracket
Forward suspension bracket (fig. 7.1)
independent, lever and spring type MacPherson, with telescopic amortizatorny racks, twisted cylindrical springs, the bottom cross-section levers and the stabilizer of cross-section stability.

Basic element of a forward suspension bracket is the telescopic amortizatorny rack combining functions of the directing mechanism and a dempfiruyushchy element of vertical fluctuations of a wheel concerning a body. On an amortizatorny rack are collected a twisted cylindrical spring 4 (fig. 7.2)
... the top support 1 assembled with the bearing through which load of a car body is transferred...
... the buffer of compression 2 assembled with a protective rubber cover 3.
Dempfiruyushchim serves as an element of a rack the telescopic shock-absorber of double action.
The Amortizatorny rack is connected to the bottom lever 7 (see fig. 7.1
) suspension brackets a spherical support 5. The bottom levers are attached to a cross-piece of the 12th lobby of a suspension bracket with the help сайлентблоков 10 and rubber plugs 8 of a back support. The cross-piece, in turn, is attached to body longerons.
The bar of the 11th stabilizer of cross-section stability with the rubber plugs established on it is connected to a cross-piece of the 12th lobby of a suspension bracket of the car two brackets 9, and with levers of the 7th lobby of a suspension bracket — racks of the 6th stabilizer.
Corners of a cross-section inclination of axes of turn of wheels (disorder corners) in operation regulate moving of rotary fists of rather amortizatorny racks at the weakened nuts of bolts of fastening of fists to racks, and a convergence of forward wheels — change of length of drafts of a steering. Corners of a longitudinal inclination of axes of turn of wheels are set structurally and are not regulated.
