Back suspension bracket — semi-independent type with a cross beam, telescopic racks and cylindrical springs. The kinematics of a suspension bracket provides strictly vertical movement of wheels. In a design shock-absorbers of bilateral action are used. Details of a back suspension bracket are shown in fig. 5.12.

The angles of installation of back wheels are not regulated and have the following values:

disorder       1 ° ±45'

convergence       (1±4) mm
