VEHICLE SUSPENSION ON TRAILING ARMS Russian patent published in 2008 - IPC B60G7/00 

FIELD: transportation.

SUBSTANCE: suspension of vehicle consists of trailing arms. Each of trailing arms is made with variable section in vertical plane up to rectangular section before its inset with beam axle of vehicle. The said arm is divided by vertical notch into two symmetrical parts from point of its pinning to vehicle frame and place of its attachment to mentioned vehicle beam axle with possibility to vary ratio between thickness and height of trailing arm section and width of notch.

EFFECT: design simplicity due to suspension stabiliser elimination, high rigidity of suspension trailing arm while its weight and dimensional parameters are equal to the same parameters of known arms, more durable operation of suspension pneumatic element and suspension survivability under destruction of one of the trailing arm front parts.
