Abstract

La présente invention concerne une suspension à roues indépendantes d'un véhicule à deux voies, comprenant un support de roue (1) sur lequel se trouvent des points d'articulation (1b, 1c, 1d) destinés à des bielles (2, 3, 4) et situés sensiblement en dessous du centre de roue (m) qui prennent appui directement ou indirectement sur la structure du véhicule à leur autre extrémité, et sur lequel se trouve un élément de trajectoire de guidage (7) au moins partiellement incurvé s'étendant sensiblement en direction verticale. Un élément de guidage (8) qui de son côté est fixé directement ou indirectement à la structure du véhicule, est guidé sur l'élément de trajectoire de guidage, sensiblement au dessus du centre de roue, pour pouvoir se déplacer le long de l'élément de trajectoire de guidage. La suspension de l'invention comprend également un ressort (5) qui agit en dernier lieu entre la structure et le support de roue, et un amortisseur de vibrations (10) connecté en parallèle dudit ressort. Selon l'invention, le ressort et l'amortisseur de vibrations prennent appui sur une bielle ou directement sur le support de roue en dessous ou faiblement au dessus du centre de roue. L'amortisseur de vibrations se présente de préférence sous la forme d'un amortisseur rotatif dont le boîtier prend appui en dernier lieu sur la structure du véhicule et dont le bras oscillant est relié en dernier lieu directement ou indirectement au support de roue.
