(EN) ADJUSTABLE CHASSIS FOR A MOTOR VEHICLE
(FR) CHÂSSIS AJUSTABLE POUR UN VÉHICULE À MOTEUR
Abstract
(EN)
The present disclosure relates to a chassis (1) for a motor vehicle, comprising a passenger compartment cell (2), a front frame (3) and a rear frame (4), which are arranged along a longitudinal direction (100) of the chassis (1). The frame front (3) and the rear frame (4) each comprise two longitudinal members (31, 32; 41, 42) and a cross member (35; 45) forming a substantially C-shaped structure. The chassis (1) allows the adjustment of the track width and/or the pitch of the motor vehicle. To adjust the track width, the chassis (1) is adapted for the attachment of each longitudinal member (31, 32; 41, 42) of a frame (3, 4) to the passenger compartment cell (2) at a plurality of positions that are spaced apart in the transverse direction, in such a way as to allow an adjustment of the transverse distance between the two longitudinal members (31, 32; 41, 42). To adjust the pitch, each longitudinal member (31, 32; 41, 42) of a frame (3, 4) is provided with at least one attaching assembly (53) for attaching a suspension (7) of a respective wheel of the motor vehicle. The attaching assembly (53) is adapted for attaching the suspension (7) at a plurality of positions that are spaced apart in the longitudinal direction, in such a way as to allow an adjustment of the longitudinal distance of the suspension (7) from the passenger compartment cell (2).

(FR)
La présente invention porte sur un châssis (1) pour un véhicule à moteur, lequel châssis comprend une cellule de compartiment passagers (2), un châssis avant (3) et un châssis arrière (4), qui sont disposés le long d'une direction longitudinale (100) du châssis (1). Le châssis avant (3) et le châssis arrière (4) comprennent chacun deux éléments longitudinaux (31, 32; 41, 42) et une entretoise (35; 45) formant une structure sensiblement en forme de C. Le châssis (1) permet l'ajustement de la largeur de voie et/ou du pas du véhicule à moteur. Pour ajuster la largeur de voie, le châssis (1) est apte à la fixation de chaque élément longitudinal (31, 32; 41, 42) d'un châssis (3, 4) à la cellule de compartiment passagers (2) en une pluralité de positions qui sont mutuellement espacées dans la direction transversale, de façon à permettre un ajustement de la distance transversale entre les deux éléments longitudinaux (31, 32; 41, 42). Pour ajuster le pas, chaque élément longitudinal (31, 32; 41, 42) d'un châssis (3, 4) comporte au moins un ensemble de fixation (53) pour fixer une suspension (7) d'une roue respective du véhicule à moteur. L'ensemble de fixation (53) est apte à la fixation de la suspension (7) en une pluralité de positions qui sont mutuellement espacées dans la direction longitudinale, de façon à permettre un ajustement de la distance longitudinale de la suspension (7) par rapport à la cellule de compartiment passagers (2).
