7.2.1. Features of a design
Back suspension bracket (fig. 7.2) semi-dependent, lever and spring with the longitudinal levers pivotally fixed on a body of the car and connected among themselves by a cross beam of U-shaped section. Longitudinal levers are connected to a saylentblokama body. Springs of a suspension bracket of variable rigidity (barrel-shaped). The top and lower ends of springs rely on elastic rubber laying.
Fig. 7.2. Back suspension bracket: 1 – support of the shock-absorber of a back suspension bracket; 2 – compression buffer; 3 – shock-absorber of a back suspension bracket; 4 – laying of a spring of a back suspension bracket; 5 – spring of a back suspension bracket; 6 – saylentblok; 7 – beam of a back suspension bracket
In a beam of a suspension bracket the stabilizer of cross stability of the torsion type is installed.
On suspension bracket levers bolts fixed the lower ends of telescopic hydraulic shock-absorbers of bilateral action. The top ends of shock-absorbers are attached to a body through rubber pillows.
The naves of back wheels executed for a single whole with brake drums are established on two conic roller bearings.
The angles of installation of back wheels are set structurally and in operation are not regulated. Only control of a condition of a back suspension bracket on the angles of installation is possible (see. "Check and adjustment of angles of installation of wheels").
