Description
Technical field
This utility model is related to a kind of automobile component, the more particularly to torsion beam on automobile.
Background technology
Torsion beam of automobile belongs to semi-independent suspension, connects left and right trailing arm, the vehicle side in vehicle traveling process by crossbeam
When inclining, crossbeam is twisted deformation therewith, the control stability of automobile is improved so as to provide torsional rigidity, has phase with stabiliser bar
Same effect, this twist-beam suspension is the first-selection of economy car on market at present.
Torsion beam has two kinds of forms, and one kind is V-type plate beam, and using sheet metal forming, this structure generally will
Plus torque arm or reinforcing plate, the weight of such part certainly will increase;Another is tube stamping formula, using pipe punching press
Molding, its section are also V-type, and relative to V-type plate beam punching type crossbeam, this structure has the lightweight feature of simple structure,
Unsprung mass can be greatly decreased, the comfortableness of vehicle is improved.
The production technology of tube stamping formula torsion beam have shaped by fluid pressure, thermoforming, cold stamping shaped three kinds, three of the above life
The raw material of production. art is without seam welded tube, and higher to the technical requirements without seam welded tube, this adds increased the system without seam welded tube
Difficulty and manufacturing cost are made, so as to cause the cost of raw material of closed torsion beam too high.
Utility model content
In view of the above-mentioned deficiency of prior art, technical problem to be solved in the utility model is to provide a kind of automobile
Torsion beam.
The technical solution of the utility model is as follows:A kind of torsion beam of automobile, with torsion beam body, it is characterised in that:Institute
It is symmetrical formula structure to state torsion beam body, is welded after mould molding by sheet material, and weld seam is located at torsion beam body
The centre position of top surface, and weld seam extends along its length, the termination section of the torsion beam body is quarter bend shape, torsion beam body
The cross section of interlude is " V " shape, and top board and the base plate of the interlude stick together, in being connected for interlude top board and base plate
Place is formed with space, has First Transition section and the second changeover portion between the termination section and interlude, the First Transition section
Cross section is the concave stood upside down, and the cross section of the second changeover portion is " V " shape, between the top board and base plate of second changeover portion
With gap, the directional smoothing transition of the shape of cross section of the torsion beam body from termination section toward interlude.
Preferably, high-strength steel sheet of the torsion beam body by thickness for 2.5-5mm is welded after mould molding
Form.
For the ease of positioning to trailing arm, trailing arm and torsion beam body is made to be connected firmly, reliable, the torsion beam body two ends
Top board and base plate outwards one extends, form flange, form bayonet socket between the upper lower flange of one end.
Beneficial effect:This utility model substitutes the production raw material without seam welded tube as torsion beam using sheet material, from basic
On reduce the production cost of torsion beam, and effectively increase the production efficiency of product;Meanwhile, this utility model moulding letter
It is single, torsion beam bending stiffness, longitudinal rigidity and lateral rigidity can be effectively improved, torsion beam distorting stress is effectively reduced, be improved
Fatigue durability.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figures 1 to 5, the torsion beam of automobile has torsion beam body 1, and the torsion beam body 1 is symmetrical formula
Structure, is welded after mould molding by high-strength steel sheet of the thickness for 2.5-5mm.Weld seam 2 is pushed up positioned at torsion beam body 1
The centre position in face, and weld seam extends along its length.During torsion beam body 1 has the termination section 3, middle position at left and right two ends
Between First Transition section 4 between section 5 and termination section 3 and interlude 5 and the second changeover portion 4 ' constitute.Wherein, torsion beam body 1
Termination section 3 is quarter bend shape, and the cross section of 1 interlude 5 of torsion beam body is " V " shape, and top board and the base plate of the interlude 5 are abutted in
Together, space 6 is formed with the connecting place of base plate in 5 top board of interlude.First Transition section 4 is located at termination section 3 and the second transition
Between section 4 ', the cross section of the First Transition section 4 is the concave stood upside down, and the cross section of the second changeover portion 4 ' is " V " shape, should
There is between the top board and base plate of the second changeover portion 4 ' gap 8.The shape of cross section of torsion beam body 1 is from termination section 3 toward centre
The directional smoothing transition of section 5.Outwards one extends the top board and base plate at 1 or so two ends of torsion beam body, forms flange 7, together
Bayonet socket is formed between the upper lower flange 7 of one end.
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area
Member just can make many modifications and variations according to design of the present utility model without the need for creative work.Therefore, all this technology necks
In domain, technical staff passes through logical analyses, reasoning or limited reality on the basis of existing technology according to design of the present utility model
Available technical scheme is tested, all should be in the protection domain being defined in the patent claims.
