Abstract
The invention relates to an axle assembly for a commercial vehicle, having an axle produced from a first metal material and at least one trailing link produced from a second metal material which has a connecting portion with a seat which the axle sits with a hollow coupling portion such that the axle and the trailing link are in torque-proof engagement with one another. In an axle assembly of this type, an optimally reliable connection between the individual components of 'trailing link' and 'axle' is ensured in a cost-effective and simple manner in that the characteristics of the metal materials from which the connecting portion of the trailing link and the coupling portion of the axle are made, are coordinated with one another such that the modulus of elasticity of the connecting portion is less than the modulus of elasticity of the coupling portion and/or the breaking strength of the connecting portion is greater than the breaking strength of the coupling portion encompassed by the connecting portion in the joined state, and/or the yield strength R, or if the metal material does not have a clearly defined yield strength R, the proof stress Rof the metal material, of which the connecting portion of the trailing link is made, is higher than the yield strength Ror proof stress Rof the metal material of the coupling portion, encompassed by the connecting portion, of the axle.
