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

[0110] Figure 1 to Figure 3 Shown shaft linkage 1 and Figure 5 to Figure 8d The shown axle linkages 101 are each part of a non-drive axle of a tractor-trailer, not shown here, for a tractor-trailer, also not shown.

[0111] The shaft linkage 1 here comprises a shaft 2 formed as a shaft profile, which shaft can be provided in a tubular configuration. A longitudinal transmission rod 8 is each provided on the ends of the shafts 2 .

[0112] The shaft 2 is made of a hollow sheet steel profile and ends in two couplings 4 arranged on the end sides, one of which is in the figure 2 shown in. The coupling 4 on the end side has a structure formed as a hollow profile 5 which is open towards its free end.

[0113] From one side of the motor vehicle to the other, the shaft 2 has an approximately square cross-section in its central region, in contrast to the coupling 4, and is also provided with a pressed-in guide groove deformation 6, so that a torsion is formed. The torsional resi...

Abstract

The invention relates to an axle assembly for a commercial vehicle, having an axle (2; 102) manufactured from a metal material and having at least one trailing arm (8; 103, 104) manufactured from a metal material, said trailing arm comprising a connection section (9; 118) having a receptacle (9a; 112), in which the axle (2; 102) with a hollow coupling section (4; 110) is seated such that the axle(2; 102) and the trailing arm (8; 103, 104) are connected to one another rotationally fixed. In the axle assembly, the properties of the metal materials of the connection section of the trailing arm and of the coupling section of the axle are adapted to one another such that the modulus of elasticity of the connection section is less than the modulus of elasticity of the coupling section and / or the breaking strength of the connection section is greater than the breaking strength of the coupling section, and / or the yield point Res or - if the metal material does not have a pronounced yield point - the elongation limit Rpo,2 of the connection section of the trailing arm is higher than the yield point Res or elongation limit Rpo,2 of the metal material of the coupling section of the axis which the connection section encloses.

Description

technical field [0001] The invention relates to a shaft linkage for a non-drive shaft of a commercial vehicle, the shaft linkage 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 which is provided with a receptacle in which the shaft is arranged via a hollow coupling in such a way that the shaft and the longitudinal transmission rod are connected to each other in a rotationally fixed manner . Axle linkages of this type are used, for example, on trucks and on trailers or trailers for towing trucks. Background technique [0002] Shaft structures of this type, also referred to as "hard shafts", are widely known. Typically, such a shaft includes a longitudinal transmission rod pivotally coupled to the motor vehicle frame at one end by a suitable hinge and supported on the motor vehicle at the other end...
