DEFINITION

Classification: 267/230

Quadrilateral suspension:

(under subclass 229) Spring device including four rigid links pivoted together to form a four-sided polygon, wherein the relatively moving parts of the vehicle are connected to different links, and one link servers as the "lever" connected to the spring element, whereby relative movement between the vehicle parts causes the shape of the polygon to

change.

(1) Note. Typically, the links comprise the upper and lower control arms, the wheel axial support, and the vehicle chassis, and the arrangement is applied to separate wheels as an "independent suspension".
