Title (EN) VEHICLE COMPRISING A REAR WHEELSET WITH CONTROLLED LONGITUDINAL DISPLACEMENT IN THE EVENT OF A REAR IMPACT
(FR) VEHICULE COMPORTANT UN TRAIN ARRIERE A DEPLACEMENT LONGITUDINAL CONTROLE EN CAS DE CHOC ARRIERE
Abstract:
(EN) The invention relates to a vehicle (1) which comprises a chassis (13) to which there is attached a rear wheelset (3) with a deformable crossmember (31), the wheeelset (3) comprising, on each side of the deformable crossmember (31), a longitudinal suspension arm (32) comprising an articulation (34) in the forward part (322) of the suspension arm (32), the chassis (13) comprising a structural element positioned in the forward continuation of the suspension arm (32) and designed to extend opposite, and to limit the longitudinal displacement (x) of, the forward part (322) of the suspension arm (32), such a longitudinal displacement occurring in an impact on the rear of the vehicle (1) which causes said articulation (34) to break, the vehicle comprising blocking means designed to block the transverse displacement (y) of the forward part (322) of the suspension arm (32) in said impact.
(FR) L'invention concerne un véhicule (1) qui comporte un châssis (13) sur lequel est fixé un train arrière (3) à traverse déformable (31), le train arrière (3) comportant de chaque côté de la traverse déformable (31) un bras de suspension longitudinal (32) comportant une articulation (34) en partie avant (322) du bras de suspension (32), le châssis (13) comportant un élément de structure positionné dans le prolongement avant du bras de suspension (32) et adapté pour s'étendre en vis-à-vis et limiter le déplacement longitudinal (x) de la partie avant (322) du bras de suspension (32), un tel déplacement longitudinal se produisant lors d'un choc sur l'arrière du véhicule (1) qui entraîne la rupture de ladite articulation (34), le véhicule comportant des moyens de blocage adaptés pour bloquer le déplacement transversal (y) de la partie avant (322) du bras de suspension (32) lors dudit choc.
