Forward and back suspension brackets of motor vans and buses (fig. 6.1, 6.2, 6.3) are executed on longitudinal springs with hydraulic shock-absorbers.

In a forward suspension bracket over the basic spring the rubber spring of compression is established, in a back suspension bracket over the basic spring the additional spring (in a back suspension bracket of buses instead of an additional spring the rubber spring of compression is established) is established.

Forward and back springs of cars on length are asymmetrical (from центрового a bolt to an ear).

At installation of forward and back springs shorter end should be turned forward.

In a suspension bracket multisheet springs can be applied as малолистовые, and. In case of need dismantlings of springs before assemblage grease their sheets with graphitic greasing.

Fastening of the forward ends of springs to a frame is executed with the help резинометаллических hinges, the back ends of springs — with the help резинометаллических hinges and earrings. The inhaling of their nuts should be made for correct work of these hinges at the straightened springs.

Care of a suspension bracket consists in periodic check of fastening of springs, shock-absorbers, nuts of step-ladders.
