Abstract

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.
