Problems solved by technology

[0013] The disadvantage against these advantages is that, despite the use of modern machining techniques such as hydroforming, the known shaft linkages are still cost-intensive to manufacture
It follows that shaft linkages manufactured according to EP 0 713 791 B1 are not suitable for absorbing the resulting higher loads with sufficient safety in practical use in commercial vehicles

Embodiment Construction

[0123] Figure 1 to Figure 3 Shaft linkage shown in 1 and Figures 5 to 8d The axle linkages 101 shown are in each case part of a non-drive axle of a trailer, not shown here, which is used to tow a load vehicle, likewise not shown.

[0124] The shaft drive 1 here comprises a shaft 2 formed as a shaft profile, which can be provided in a tubular configuration. At each end of the shaft 2 a longitudinal drive rod 8 is provided.

[0125] The shaft 2 is made of a hollow sheet steel profile and terminates in two couplings 4 on the end faces, one of which is in the figure 2 shown in . The end-side coupling 4 has a design in the form of a hollow profile 5 which is open toward its free end.

[0126] The shaft 2 , which runs from one side of the motor vehicle to the other, has an approximately square cross-section in its central region, unlike the coupling 4 , and is also provided with a pressed-in guide groove deformation 6 , so that a torsion Section 6 a , over which the torsiona...

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 in 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 ReS, or if the metal material does not have a clearly defined yield strength ReS, the proof stress Rp0.2 of the metal material, of which the connecting portion of the trailing link is made, is higher than the yield strength ReS or proof stress Rp0.2 of the metal material of the coupling portion, encompassed by the connecting portion, of the axle.

Description

technical field [0001] The invention relates to a shaft linkage for a non-driven axle of a commercial vehicle, comprising a shaft made of a first metallic material and further comprising at least one longitudinal transmission rod made of a second metallic material, The longitudinal transmission rod is provided with a connecting section with a receptacle in which the shaft is arranged via a hollow coupling such that the shaft and the longitudinal transmission rod are connected to one another in a rotationally fixed manner. . Such shaft linkages are used, for example, in trucks and trailers or trailers towing trucks. Background technique [0002] Such shaft constructions, also known as "hard shafts", are widely known. Typically, such an axle comprises a longitudinal transmission rod pivotally coupled at one end to the vehicle frame by a suitable hinge and supported at the other end by a spring / buffer combination on the vehicle frame. superior. In this way, a simple and fle...
