Abstract
An antiroll device for the suspension of a motor vehicle comprises a torsion bar and two lateral links articulated to this bar and to two lateral shock absorbers. At least one of the links () is telescopic and includes a piston () mounted so it can slide in a piston tube () via a rod () connected to the hinge connecting the link to the adjacent shock absorber, the piston being mobile due to the movement of this connection and cooperating in compression with return means () housed inside the said tube. The return means include two compressible stop components (and) which are designed to impart to the link a progressive stiffness which increases with the amplitude of the movements of the axis of the adjacent wheel (), so that this wheel is substantially uncoupled from the torsion bar or coupled to it for small or large-amplitude movements respectively.
