Embodiment 1

[0037] Basic as attached figure 1 Shown: high-performance torsion beam formed by control stamping, including the beam, which is divided into middle section 1, transition section 2 and outer section 3 from the middle to both ends, and the cross section of middle section 1, transition section 2 and outer section 3 are all closed sections, and the cross-sectional shapes of the middle section 1, the transition section 2 and the circumscribed section 3 are all different, such as figure 2 , image 3 , Figure 4 As shown, the cross-section of the middle section 1 is V-shaped (or U-shaped), the cross-section of the outer section 3 is square (or circular), and the transition section 2 is used to connect the middle section 1 and the outer section 3, and make the middle section 1 and the circumscribed segment 3 make a smooth transition. Such as figure 2 As shown, the beam includes the outer layer 5 and the inner layer 4, and there is a gap between the outer layer 5 and the inner la...

Embodiment 2

[0051] The difference between the present embodiment and the first embodiment is that the honeycomb wax stick is directly formed in the pipe. When stamping pipes, use such as Image 6 The cooling mechanism shown, the cooling mechanism includes a fixed disk 11, a cooling pipe 12 and a drive shaft 18, the cooling pipe 12 is evenly distributed on the right end surface of the fixed disk 11, the cooling pipe 12 includes a skeleton, a sealing film 17 and an inner rod 16, and the skeleton is composed of Several connecting rod groups are formed, and the connecting rod groups are distributed in a circular array with the inner rod 16 as the center, such as Figure 8 As shown, the connecting rod group includes a first strut 13 and a second strut 14 that are hinged to each other, the left end of the first strut 13 is hinged to the right end of the fixed plate 11, and the right end of the second strut 14 is hinged on the same On the limit ring; such as Figure 7 As shown, the first pole ...

Abstract

The invention relates to the technical field of torsion beams, in particular to a high-performance torsion beam for pipe production stamping formation. The beam comprises a beam body, the beam body isdivided into a middle segment, transition segments and external connection segments from the middle to the two ends in sequence, the cross sections of the middle segment, the transition segments andthe external connection segments are closed cross section, and the areas of the cross sections of the middle segment, the transition segments and the external connection segments are gradually increased in sequence; weight reduction holes are formed in the beam body. By adopting the scheme, the technical problem of large total weight of the torsion beam for pipe production stamping formation can be solved.

Description

technical field [0001] The invention relates to the technical field of torsion beams, in particular to a high-performance torsion beam formed by control stamping. Background technique [0002] Torsion beam suspension is a type of car rear suspension. It uses a torsion beam to balance the up and down jump of the left and right wheels to reduce the shaking of the vehicle and maintain the stability of the vehicle. [0003] Existing torsion beams are pipes formed by controlled stamping, which have good fatigue resistance, but more raw materials are used, and the weight of the beam is larger; the beam is made of a single-piece V-shaped plate, which reduces the weight , which better meet the design requirements of lightweight, but the single-piece beam has low torsion resistance and fatigue fracture resistance, and is easy to torsion and fracture, which reduces the service life of the torsion beam and increases the risk factor of vehicle driving. Contents of the invention [00...
