Patent

CA 2651976

The invention relates to an axle unit having a vehicle axle which has a rigid axle body, which is embodied for example as an axle tube (8), having in each case one control link (6, 7) at each side of the vehicle longitudinal central plane, which control link can be articulatedly connected, at a first front end (9, 10), to a bearing point which is fixed to the chassis, and, spaced apart therefrom, is rigidly connected to the axle body (8), and which control link, in the region of its rear end (17, 18) which is situated opposite the front end (9, 10), forms the lower rest of a spring element, on the upper side of which the vehicle chassis is supported. The axle body (8) and the two control links (6, 7) are formed together from two in each case substantially single-piece formed part halves (2, 3) which are connected to one another along a parting joint (4) which runs for example in a substantially horizontal plane, such that the axle body (8) rigidly connects the two control links (6, 7) to one another. The axle body (8) is stiffened, at least in the connecting regions of the axle body (8) to the two control links (6, 7), by at least one additional stiffening element (15, 16; 17; 18; 19, 20).

L'invention concerne un ensemble d'essieu avec un essieu de véhicule présentant un corps d'essieu rigide, réalisé par exemple sous forme de tube d'essieu (8), et avec une bielle de poussée respective (6, 7) de part et d'autre du plan médian longitudinal du véhicule. La bielle peut être articulée en un point d'appui solidaire du châssis à une extrémité avant (9, 10) et, à distance de ce point d'appui, est assemblée rigidement au corps d'essieu (8); dans la région de son extrémité arrière (17, 18) opposée à l'extrémité avant (9, 10), elle forme le support inférieur d'un élément de ressort sur le dessus duquel s'appuie le châssis du véhicule. Le corps d'essieu (8) et les deux bielles de poussée (6, 7) sont conjointement formés à partir de deux moitiés de pièce façonnée (2, 3) réalisées chacune sensiblement d'un seul tenant et reliées entre elles le long d'un joint de séparation (4) s'étendant par exemple sensiblement dans le plan horizontal, de sorte que le corps d'essieu (8) relie rigidement entre elles les deux bielles de poussée (6, 7). Le corps d'essieu (8) est, au moins dans ses régions de liaison avec les deux bielles de poussée (6, 7), renforcé par au moins un élément de renforcement supplémentaire (15, 16; 17; 18; 19, 20).
