Abstract
A motor vehicle axle system including two longitudinal arms made of molded material and a torsionally flexible cross bracing made of high strength material different from the material of the arms, each arm including a lug for assembling by structural bonding the cross bracing to the arms. Each lug has an assembling edge configured to be assembled to one end of the cross bracing by generating self-binding with a surface of the cross bracing, an adhesive layer being applied between the assembling edge and the surface of the cross bracing, and the assembling edge of each lug has a variable thickness along its periphery and in the direction of the lug axis, the thickness being selected so as to minimize stresses exerted on the adhesive in the assembling zone. A method assembles the motor vehicle axle system.
