High-strength automobile torsion beam

Technical Field

The utility model relates to an auto-parts field especially relates to a high strength automobile torsion beam.

Background

The torsion beam type suspension is one type of automobile rear suspension, wheels of an automobile are arranged at two ends of a torsion beam, and the torsion beam can balance up-and-down jumping of left and right wheels so as to reduce shaking of the automobile and keep the stability of the automobile. The torsion beam has simple structure and large bearing capacity, and is generally used for load-carrying trucks, common passenger cars and some special vehicles.

In order to reduce the weight, the conventional torsion beam is generally hollow, but the torsion beam also needs to bear a certain torsion action in the driving process of an automobile, and after the torsion beam is used for a long time, the torsion beam is easy to be subjected to torsion deformation, and the side wall of the torsion beam is sunken.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high strength automobile torsion beam for torsion beam lateral wall provides the support.

In order to achieve the above purpose, the technical scheme of the utility model is that: high strength automobile torsion beam, comprising a main body, be equipped with the confined cavity in the main part, the main part includes left end head section in proper order along the axial, left changeover portion, the interlude, right changeover portion and right-hand member head section, the external diameter of interlude is less than the external diameter of left end head section and right-hand member head section, the interlude is the V-arrangement along vertical cross-section, left side changeover portion and right changeover portion are the spill along vertical cross-section, left end head section and right-hand member head section are described for mouthful along vertical cross-section, be equipped with the strengthening rib fixed with the main part lateral wall in the cavity, there is the contained angle strengthening rib and the axial of main.

The beneficial effect of this scheme does: the reinforcing ribs can support the side wall of the cavity after being positioned in the cavity, and the torsional rigidity of the torsion beam is improved, so that the torsion beam is prevented from deforming in the using process, and the service life of the torsion beam is prolonged.

Further, the number of the reinforcing ribs is at least two.

The beneficial effect of this scheme does: the quantity of strengthening rib increases, and is better to the support effect of cavity lateral wall, further avoids torsion beam to take place deformation.

Furthermore, reinforcing ribs are arranged in the left transition section and the right transition section.

The beneficial effect of this scheme does: when torsion beam received the effect of twisting reverse, left changeover portion and right changeover portion took place deformation easily, and two strengthening ribs are located left changeover portion and right changeover portion respectively can be better play the supporting role to the lateral wall of left changeover portion and right changeover portion to improve the intensity of left changeover portion and right changeover portion.

Furthermore, the reinforcing ribs are in a cross shape.

The beneficial effect of this scheme does: the cross reinforcing ribs can support the transverse direction and the vertical direction of the side wall of the cavity, and the supporting effect is better.

Further, the reinforcing ribs are perpendicular to the axial direction of the main body.

The beneficial effect of this scheme does: the strengthening rib in this scheme traverses the cavity, and is better to the support effect of cavity lateral wall.

Further, the tip that the strengthening rib is close to the main part lateral wall is equipped with the holding tank that can hold the soldering paste.

The beneficial effect of this scheme does: in order to improve the strength of the torsion beam, the torsion beam needs to be subjected to heat treatment after being formed, and when the torsion beam is subjected to heat treatment in the scheme, the reinforcing ribs are fixed on the main body through soldering paste. Because the space of cavity is less, it is great relatively to carry out the welded degree of difficulty to the strengthening rib in stretching into the cavity with welding set, need not in this scheme alone to weld the strengthening rib, reduces the processing step, effectively reduces the processing degree of difficulty, improves torsion beam's production efficiency.

Further, the holding tank is just to the welding seam on the main part.

The beneficial effect of this scheme does: when the torsion beam is processed by adopting the plate, a welding seam exists on the formed torsion beam along the axial direction, the welding seam can be welded for improving the strength of the torsion beam, but the plate has a certain thickness, and soldering paste is difficult to permeate into the torsion beam along the welding seam, so that the welding part is still easy to damage. In this scheme, can follow after the soldering paste melts in the holding tank and be close to cavity one end and welding seam contact to fix the welding seam in the follow, improve the intensity of welding seam department.

Further, the inner wall of the main body is provided with a groove opposite to the accommodating groove.

The beneficial effect of this scheme does: the molten soldering paste receives the limiting displacement of holding tank and the gathering is around the strengthening rib tip, avoids the welding between strengthening rib and the main part because the soldering paste reduces and stabilize inadequately.

Furthermore, the left transition section and the right transition section are symmetrical along the central line of the middle section.

The beneficial effect of this scheme does: the torsion beam is symmetrical, the damage degree of two ends is equivalent after the torsion beam is used for a period of time, the condition that one end is easy to damage can not occur, and the service life of the torsion beam is longer.

Furthermore, the surfaces of the left end head section, the left transition section, the middle section, the right transition section and the right end head section are all arc surfaces.

The beneficial effect of this scheme does: after the torsion beam is formed, a coating needs to be coated on the surface, and the edges and corners of the surface are more easily worn during use, so that the coating is damaged, and the service life of the torsion beam is shortened. The surface of end section, left changeover portion, interlude, right changeover portion and right-hand member end section is the arcwall face in this scheme, does not have the edges and corners, can avoid the emergence of above-mentioned condition.
