Definitions
- the invention is based on the object of creating a transverse strut for a torsion-beam axle of a motor vehicle which combines the functions of track, camber and roll stiffness. This object is achieved according to the invention in the features of patent claim 1.
- the cross strut is now produced from an extruded profile which is composed of a jacket tube and a longitudinal bead which extends radially inwards from the inner surface of the jacket tube, the radial extent of which is smaller than the inner radius of the jacket tube.
- connection of a jacket tube representing a bending profile to an inner longitudinal bead embodying a torsion bar allows, as in the case of the individual components which belong to the prior art, to independently trim the track, camber and roll stiffness.
- the bending stiffness of the cross strut is improved due to the inherent inertia of the longitudinal bead.
- the bending stiffness continues to be positively influenced by the distance of the longitudinal bead from the common profile center of gravity with the casing tube (Steiner portion).
- the stiffness of the camber can be increased without additional material.
- a significantly improved material utilization can also take place in the casing tube.
- the invention provides within the framework of the basic concept of the invention that the wall of the casing tube in its middle length region opposite the edge of the longitudinal bead via a Part of its circumferential length is left out.
- This configuration of the cross strut specifically serves to reduce its torsional rigidity.
- torsional stiffness of the cross strut can take place within the scope of the features of claim 2 in that the wall of the casing tube is recessed in the region of its central transverse plane over approximately half the circumferential length. In the direction of the circumferentially closed ends of the casing tube, the circumferential length of the cutout is then continuously reduced to zero.
- the axial length of the recess to the axial length of the circumferentially closed ends of the casing tube is about 4: 1 to 6: 1, preferably about 5: 1.
- the size of the axial length of the closed ends of the casing tube depends on the respective requirements, in particular on the type of joining of the cross strut with the trailing arms.
- the longitudinal bead is spaced from the inner surface of the casing tube by a radial web. This radial web takes on the function of a push strut.
- the web extends according to claim 6 in the central longitudinal plane of the tubular casing.
- the radial height of the web is larger than the inner radius of the casing tube.
- the radial height of the web plus the radial extension of the longitudinal bead to the inside diameter of the casing tube is preferably about 0.8: 1, 4, preferably about 1: 1, 2.
- the thickness of the web is dimensioned approximately equal to the thickness of the wall of the jacket tube, these thicknesses can be optimally matched in such a way that the edge fiber spacing for the jacket tube can be distributed symmetrically. This increases the material utilization and minimizes the weight.
- the outer diameter of the longitudinal bead is dimensioned approximately equal to three times the thickness of the web.
- the cross strut is formed from aluminum or an aluminum alloy.
- Figure 1 in a schematic perspective a torsion beam axle for a
- Figure 2 is an enlarged perspective view of a transverse strut of the torsion beam axis of Figure 1;
- Figure 3 is a side view of the cross strut of Figure 2 and
- FIG. 4 shows an enlarged front view of the cross strut in the direction of arrow IV in FIG. 3.
- 1 in FIG. 1 denotes a torsion-beam axle for a motor vehicle.
- the torsion beam axle 1 generally comprises two trailing arms 2 (not explained in more detail) and a transverse strut 3 connecting the trailing arms 2.
- the transverse strut 3 is designed cylindrically overall and passes through recesses 4 in the trailing arms 2 which are adapted to the outer contour of the transverse strut 3.
- the cross strut 3 consists of an extruded profile made of an aluminum alloy.
- This extruded profile is composed of a jacket tube 5 as a bending profile and a web 7 which extends radially inward from the inner surface 6 of the jacket tube 5 as a push strut with an edge-side longitudinal bead 11 as a torsion bar.
- the central longitudinal plane 8 of the web 7 runs through the longitudinal axis 9 and thus also through the central longitudinal plane MLE of the casing tube 5.
- the thickness D of the web 7 corresponds approximately to the thickness D1 of the wall 10 of the casing tube 5.
- the longitudinal bead 11 is tubular.
- the radial extent RE of the longitudinal bead 11 is approximately equal to three times the thickness D of the web 7.
- the radial height H of the web 7 is larger than the inner radius IR of the casing tube 5, but smaller than the inner diameter ID.
- the ratio of the radial height H of the web 7 plus the radial extent RE of the longitudinal bead 11 in relation to the inner diameter ID of the casing tube 5 is approximately 1: 1, 2.
- the wall 10 of the casing tube 5 is recessed in its central length area MLB opposite the longitudinal bead 11 over part of its circumferential length UL. In the area of the central transverse plane MQE of the casing tube 5, the wall 10 is recessed approximately over half the circumferential length UL. In the direction of the ends 12 of the casing tube 5 which are closed on the circumference, the circumferential length of the cutout 13 is reduced to zero.
- the axial length L of the recess 13 is approximately 5: 1 to the length L1 of the circumferentially closed ends 12 of the casing tube 5.
