Abstract

Véhicule automobile comportant un ressort de suspension (38), une plaque d’appui inférieure (32) fixée à bras de suspension pivotant (30), et une coupelle supérieure (10) fixée à la caisse du véhicule, comprenant une semelle (12) d’appui de l’extrémité supérieure du ressort (38) et un moyeu de centrage (14) rentrant dans des spires supérieures du ressort (42), lorsque la plaque d’appui inférieur (32) et la coupelle (10) sont écartées au maximum avant le montage d’un amortisseur télescopique limitant le débattement du bras de suspension (30), le ressort (38) étant posé sur la plaque d’appui inférieure (32), le moyeu de centrage (14) comporte une longueur permettant à son extrémité de rester engagée dans les spires supérieures (42) du ressort (38) en assurant son guidage. Figure 3Motor vehicle comprising a suspension spring (38), a lower support plate (32) fixed to a pivoting suspension arm (30), and an upper cup (10) fixed to the body of the vehicle, comprising a sole (12) support of the upper end of the spring (38) and a centering hub (14) entering into upper turns of the spring (42), when the lower support plate (32) and the cup (10) are separated at most before mounting a telescopic shock absorber limiting the travel of the suspension arm (30), the spring (38) being placed on the lower support plate (32), the centering hub (14) has a length allowing at its end to remain engaged in the upper turns (42) of the spring (38) ensuring its guidance.
