Patent ID: 7871092

Claim:
A structural motor vehicle axle system, comprising: two longitudinal arms made of molded material; a torsionally flexible cross bracing made of a material different from the material of the arms, wherein each arm comprises a lug of substantially tubular closed profile and with an axis substantially perpendicular to the axis of the arms, for assembling by structural bonding the cross bracing to the arms, wherein each lug includes 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 having a variable thickness along its periphery and in a direction of the lug axis, the thickness selected to minimize stresses exerted on the adhesive layer in an assembly zone of each arm and the cross bracing.
