Definitions
- the invention relates to a torsion beam axle for motor vehicles and a method for producing a cross member therefor.
- Twist-beam axles are characterized by a vehicle-specific simple structure with a small footprint and good kinematic properties.
- the cross member connecting the two lateral trailing arms acts as a torsion profile, so that with a simultaneous deflection, a trailing arm characteristic is obtained and with reciprocal deflection, a semi-trailing arm characteristic.
- a torsion beam axle for motor vehicles is known, with two longitudinal links connected by a cross member, the cross member consisting of a hollow profile with a single-layer regionally open central section, to which tubular ends are connected on both sides.
- the cross member is tubular and has an oval elongated cutout in the central section.
- a vehicle axle according to DE 195 33 479 C2 also belongs to the prior art.
- the cross member of this axis has a recess which extends axially to the longitudinal axis of the tubular body, the recess in its edge regions being bordered at least in sections by webs which are embodied within the tubular body.
- the webs are strongly angled inwards, the height of the webs should correspond approximately to the width of the recess in the tubular body.
- the invention is therefore based on the object of improving a torsion beam axle of the known type with regard to the service life with high dynamic performance and to show a method for producing a cross member which is optimized in terms of application technology.
- the cross member connecting the two trailing arms is designed as a hollow profile with a regionally open central section that has an elongated cutout — on the other edge regions — at least in sections webs are provided.
- the ends of the cross member are closed in a tubular shape.
- the key point of the invention is the measure that the webs are curved in an arc shape, the opening angle between one on the outer circumference of the Middle section applied tangent and a tangent applied to the end of the webs between 5 ° and 90 °.
- This measure that is to say the shaping of the curved webs, places the open cut surface at the end of the trimmed area directly out of the effective area of the shear forces. This leads to a significant increase in the dynamic load capacity of the cross member. Negative influences from quality fluctuations in the blank cut are significantly reduced. Overall, the service life of the cross member and thus the torsion beam axle can be increased.
- the shaping process of the trimmed blank to the finished tube profile is improved, since the resilience is significantly reduced by the shaped web or webs. This results in a better shape tolerance for the profile.
- the opening angle is particularly advantageously between 15 ° and 70 °, as provided for in claim 2.
- the radius of the curved webs depends on the respective sheet thickness.
- the webs can be directed inwards (claim 3) or outwards (claim 4) with respect to the longitudinal axis of the cross member.
- the webs extend all the way along the entire length of the cutout. This design suggests advantages in practice, particularly in the case of heavy designs of torsion beam links.
- the webs can also extend only in the transition area from the central section to the ends, that is to say in the area in which the cut edges of the cutout converge and the cross member merges into the closed tubular profile.
- the main stresses occurring during driving are concentrated here. These can be compensated for in these areas by the webs formed according to the invention.
- a flat board is first manufactured, the geometry of which corresponds to the development of a cross member.
- the circuit board is fundamentally of rectangular configuration, concave cutouts h being produced on its longitudinal sides in the circuit board trim. The edges of the cutouts are angled in an additional shape or directly in the blank.
- the circuit board is then rolled up in a known manner in a tubular manner and joined along the longitudinal edges of the ends of the crossmember which are then adjacent to one another. This is preferably done as welding.
- the manufacture of the cross member is efficient and very easy to automate. As already explained above, the shaping of the trimmed board into the finished tubular profile shape is improved, since the return forces are significantly reduced by the shaped webs, which contributes to better profile accuracy.
- Figure 1 is a perspective view of a torsion beam axle according to the invention
- FIG. 2 shows a vertical section through the central section of a first embodiment of a cross member
- FIG. 3 shows a vertical section through the central section of a second embodiment of a cross member
- FIG. 4 shows the edge area of a section with the representation of an arched web
- Figure 5a the board of a cross member in the development
- 5b shows a cross section through the central transverse plane of a circuit board according to the representation of FIG. 5a with the representation of a first embodiment variant of the edge regions
- 5c shows a cross section through the central transverse plane of a circuit board in accordance with the illustration in FIG. 5a with the illustration of a second embodiment variant of the edge regions.
- Figure 1 shows a torsion beam axle 1 in a perspective representation.
- the twist beam axle 1 essentially comprises two wheel-guiding trailing arms 2, 3 and a cross member 4 connecting the two trailing links 2, 3.
- the cross member 4 consists of a single hollow profile with a regionally open central section 5, to which ends 6, 7 which are tubularly closed on both sides connect.
- the geometry of the cross member 4 is matched to the loads to be expected of the torsion beam axle 4 in the motor vehicle.
- the central section 5 has an oval elongated cutout 8. This results in 5 open cross sections in the central section with a circular sector-shaped, oval or V or U-shaped configuration.
- the leg length measured in cross section over the circumference in the central section 5 decreases from the ends 6, 7 towards the center of the cross member.
- Suitable receptacles 9, 10 for the ends 6, 7 of the cross member 4 are formed on the trailing arms 2, 3.
- the ends 6, 7 are fitted and joined in the receptacles 9, 10, as a rule welded. This ensures good power transmission from the trailing arms 2, 3 into the cross member 4.
- the cutout 8 has webs 11, 12 and 13, at least in sections, in an edge region (see FIGS. 2, 3 and 4).
- the webs 11, 12, 13 are curved in an arc.
- the webs 11 and 13 are directed inwards with respect to the longitudinal axis L of the cross member 4, whereas the webs 12 in the cross member 4 in the embodiment according to FIG. 3 refer to the longitudinal axis L of the cross member 4 are directed outwards.
- the curvature of the webs 11, 12 and 13 is fundamentally chosen such that the opening angles ⁇ , ⁇ and ⁇ between a tangent T1, T2 or T3 applied to the outer circumference U of the central section 5 and a tangent to the end 14, 15, 16 of the webs 11, 12 and 13 applied tangent T4, T5, T6 is between 5 ° and 90 °, preferably between 15 ° and 70 °.
- the opening angle ⁇ of the cross member 4 in the embodiment shown in FIG. 2 is approximately 66 °. Relative to the horizontal planes HE running through the cutout 8 or generally through the cross member 4, the angle ⁇ is 48 °.
- the opening angle ⁇ in the embodiment of the cross member 4 according to the illustration in FIG. 3 is 50 °. Relative to a horizontal plane HE intersecting the cross member 4, an angle ⁇ of 32 ° results.
- the opening angle ⁇ of a cross member 4 according to the illustration in FIG. 4 is 36 °. This results in an angle ⁇ of the tangent T6 from the end 16 or web 13 with respect to the horizontal plane HE of 16 °.
- the webs 11 extend over the entire length of the cutout 5. It is also possible that the webs 11, 12 or 13 are only provided in the transition area from the central section 5 to the ends 6, 7.
- a latin 17 is made of metal, for example steel, aluminum or another metallic material. This receives a sheet metal trim, so that its circumferential geometry corresponds to the development of the cross member 4.
- the basic configuration of the development is rectangular, with concave cutouts 19 being punched on the longitudinal sides 18 of the circuit board 17.
- the contour can be seen in FIG. 5a.
- the edges 20 of the cutouts are angled in an arc relative to the planes of the plate 17, as can be seen in FIGS. 5b and 5c.
- the trimmed board 17 is shaped into a tube and the longitudinal edges 21, 22 lying against one another at the ends 6, 7 are welded together. The ends 6, 7 then have the round closed cross section.
