7.2.1. Features of a design

Fig. 7.3. Back suspension bracket: 1–amortizatorny racks of a back suspension bracket; 2, 6 – longitudinal levers of a back suspension bracket; 3, 5 – arms of fastening of a beam of a back suspension bracket to a body; 4–beam of a back suspension bracket

Back suspension bracket (fig. 7.3) semi-independent, lever and spring with the longitudinal levers sharnirno fixed on a body of the car and connected among themselves by a cross-section beam of U-shaped section.

The beam 4 back suspension brackets consists of two longitudinal levers 2 and 6 and a connector which are welded among themselves through amplifiers. In a back part arms are welded on levers of a suspension bracket with eyes for fastening of shock-absorbers, and also flanges to which pins of back wheels together with boards of brake mechanisms are attached. Ahead plugs in which are pressed сайлентблоки are welded on levers of a suspension bracket.

Through сайлентблоки pass the bolts connecting levers of a suspension bracket to stamped and welded arms of 3 and 5, attached to the basis of a body by bolts.

In a beam of a suspension bracket the stabilizer of cross-section stability of torsionny type is established.

Basic element of a back suspension bracket is the telescopic amortizatorny rack combining functions of the podressorivayushchy mechanism and a dempfiruyushchy element of vertical fluctuations of a wheel concerning a body. On an amortizatorny rack are collected...

... twisted cylindrical spring 4 (fig. 7.4)...

Fig. 7.4. Amortizatorny rack of a back suspension bracket: 1–the bottom pillow of fastening of an amortizatorny rack to a body; 2–compression buffer; 3–protective cover; 4–spring; 5–telescopic shock-absorber

... the bottom pillow of 1 fastening of a rack to a body 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 bottom ends of amortizatorny racks are fixed by bolts on levers of a beam of a back suspension bracket.

The top ends of amortizatorny racks are attached to a body through rubber pillows.

Naves of back wheels are established on dvukhryadny ball bearings.

Corners of installation of back wheels are set structurally and in operation are not regulated. Control of a condition of a back suspension bracket on installation corners (is possible only see. «Check and adjustment of corners of installation of wheels»).
