Embodiment Construction

[0043] figure 1 Shown is a full view of the axle 1 according to the invention. The axle 1 includes two side beams 3 arranged in the longitudinal direction of the vehicle, and the side beams have a coupling portion 3 a coupled to a vehicle body and a coupling portion 3 b coupled to a wheel. The two trailing arms 3 are connected to one another via a cross member 2 . This cross member 2 extends in the transverse direction of the vehicle.

[0044] The crossbeam 2 consists of a single-walled metal profile 5 and each has a reinforcing plate 4 in its end section 6 , which is arranged there to stiffen the end section 6 of the crossbeam 2 . This results in a torsion-prone middle section of the cross member 2 , while its end sections 6 remain torsion-proof.

[0045] The longitudinal axis L of the cross member 2 running parallel to the transverse axis of the motor vehicle is also drawn.

[0046] The cross member 2 is formed from a single-walled metal profile 5 which, in cross-section...

Abstract

The invention relates to a vehicle axle 1 and two longitudinal ties 3 vertically arranged along the vehicle; the longitudinal tie comprises a link portion 3a connected with a vehicle body and a link portion 3b connected with vehicle wheels; an anti-bending crossbeam 2 is easy to be twisted so as to mutually connect the two longitudinal ties 3 in a transverse direction of the vehicle; the crossbeam2 is formed by a single-wall metal section bar 5; a cross section of the metal section bar has a bottom plate 7 and two side plates 8a and 8b; an end section 6 is formed by a reinforced plate 4; an edge9 of the reinforced plate 4 is connected with the metal section bar 5 and / or the longitudinal ties 3 in an annular manner; in addition, the reinforced plate 4 is connected with 11 and the bottom plate 7 of the metal section bar 5 in a dotted manner in an end portion 10 of the cross beam side. The vehicle axle uses the axle 1 to greatly improve driving performance of the vehicle through adding the reinforced plate 4; stress in the end portion 10 of the cross beam2 is not limited in a local portion, and well distributed to the whole area.

Description

technical field [0001] The invention relates to a vehicle axle as characterized in the preamble of claim 1 . Background technique [0002] Combined link axles generally have two trailing arms, to which the wheels are fastened, and which are connected to one another via a cross member. Special requirements are placed on these beams. Their end sections should be constructed as rigidly as possible in order to avoid undesired changes in track width and camber. At the same time, however, they should also be easy to twist, which is mostly achieved by the twist-easy middle section of the cross member. During operation, high stress peaks occur in the transition region between the torsion-prone middle section and the rigid end section, which have a negative effect on the service life of the combined tie rod shaft. [0003] In order to increase the rigidity of the end sections of the beam, it is known in the prior art to reinforce the end section by reinforcing plates fitted in the...
