An extruded, tubular vehicle axle for front and rear wheel applications, is formed with integral, radially outwardly extending ribs, at the radial top and bottom dead centers of the axle, and continuously extending longitudinally along substantially the entire length of the axle parallel to the axis of the axle. The opposite end portions of the axle are snugly inserted within corresponding sockets formed, for example, in a vehicle axle yoke or carrier or housing, which sockets are provided with internal grooves for snugly receiving the ribs at the respective end portions. The exterior wall surface of the axle is substantially uniform in cross-section. The interior wall surface of the axle tube may vary, at pre-selected locations, to increase or decrease the wall thicknesses at such locations. The axle resists rotation relative to the sockets, under extreme torsional loads, and resists longitudinal bending or flexing, while being of relatively light weight.
Elle a pour objet un essieu tubulaire extrudé pour les roues avant et arrière d'un véhicule. L'essieu est formé de nervures radiales projetées extérieurement depuis le centre du dessus et du dessous de l'essieu et se prolongeant le long de l'essieu, parallèlement à l'axe de ce dernier. Chacune des extrémités de l'essieu est insérée dans un emboîtement connexe, par exemple une fourche, un support ou un carter, ledit emboîtement portant des encoches dans lesquelles viennent s'ajuster les extrémités des nervures. La coupe transversale de la paroi extérieure de l'essieu est substantiellement uniforme. La paroi intérieure de l'essieu peut varier à certains endroits prédéterminés afin d'accroître ou de réduire l'épaisseur de la paroi à ces endroits. Lorsque soumis à des charges de torsion importantes, l'essieu cesse de tourner par rapport aux emboîtements. Plus ou moins léger, l'essieu résiste à la flexion longitudinale.
