Abstract
The utility model discloses a rear torsion beam assembly used in saloon car, which comprises left and right vertical arms, reinforcing plates and horizontal beams. The left and right vertical arms are welded by a vertical arm upper body and a cover plate, the section of the vertical arm upper body is a U-shaped structure with three faces closed and one face opened, the U-shaped opening is toward the side direction of wheels, the back of the vertical arm upper body is welded with the reinforcing plates, the reinforcing plates are then welded with the horizontal beams, thereby having a consistent structure. As reinforcing plates are added between the vertical arms and the horizontal beams in the utility model, the length of welding seam is added so as to improve integral strength of members effectively, enhancing torsion strength of the horizontal beams, and reducing probability that the vertical arm upper body is cracked to cause unavailable, moreover the U-shaped opening of the vertical arm upper body is toward one side of wheels, thereby reducing the deformation resulted from the vertical arm upper body during welding.
Description
Technical field
The utility model relates to a kind of rear suspension that is used for vehicle or similar devices, more particularly, relates to the back torsion beam axle assembly that a kind of car is used.
Background technology
The back torsion beam axle assembly of car generally comprises left trailing arm, right trailing arm and crossbeam at present, and trailing arm is welded by trailing arm upper body and cover plate, and crossbeam is installed between the trailing arm of the left and right sides, and weld with the trailing arm upper body of left and right sides trailing arm respectively at two ends.The trailing arm upper body of trailing arm is a blanked part, and its cross-sectional plane is that three side sealing closes, the U-shaped member of an opening, and opening makes progress, and is thin-wall part.Crossbeam is a blanked part, and cross-sectional plane is little, and belongs to thin-wall part.Therefore the contact surface of crossbeam and trailing arm upper body is also little, can the following problem of appearance in welding and use working process: 1) all belong to the reason of thin-wall part owing to trailing arm and crossbeam, influenced welding quality, the problem that in use occurs weld metal crack even drawing crack easily causes safety misadventure easily and produces hidden danger.2) same because weld all is a thin-wall part, because heat is concentrated, the trailing arm upper body of trailing arm causes distortion easily during welding.
Patent No. CN1137984 disclosed " twist beam type suspension " with a rigid twist beam, its structure is: the beam of turning round with U-shaped cross section is welded between the left and right lower arm, left and right lower arm with turn round the beam closed side and respectively be welded with a corner plate, but this structure does not solve effectively and turns round the problems of welded quality that beam exists, and can not play good effect to the raising of torsional strength.
The utility model content
Technical problem to be solved in the utility model provides a kind of back torsion beam axle assembly that can strengthen weld strength between trailing arm and the crossbeam.
The technical scheme that its technical matters that solves the utility model adopts is: the torsion beam axle assembly comprises left trailing arm, right trailing arm and crossbeam behind the automobile, is respectively arranged with brace panel between left trailing arm, right trailing arm and crossbeam.
As further improvement, described brace panel cross section is greater than crossbeam, and the thickness of described brace panel is greater than the sheet metal thickness of the trailing arm upper body of left trailing arm and right trailing arm.
The trailing arm upper body of described left trailing arm and right trailing arm is a U-shaped, and the U-shaped opening of above-mentioned trailing arm upper body is towards homonymy wheel direction.
Described brace panel is welded in parallel on the U-shaped bottom surface of described trailing arm upper body.
The beneficial effects of the utility model are: owing to set up brace panel between trailing arm and crossbeam, increased the length of weld seam, the bulk strength that can actv. improves member strengthened the torsional strength of crossbeam, reduced the trailing arm upper body and caused the possibility that lost efficacy by drawing crack.And with the opening of trailing arm upper body to wheel one side, the distortion that in the time of reducing welding the trailing arm upper body is caused.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the A-A profiles among Fig. 1.
Accompanying drawing 3 is the B-B cutaway view Amplified images among Fig. 1.
Be labeled as among the figure: 1-left side trailing arm, 2-crossbeam, the right trailing arm of 3-, 4-cover plate, 5-trailing arm upper body, 6-brace panel
The specific embodiment
Torsion beam axle assembly behind the car comprises left trailing arm 1, right trailing arm 3 and crossbeam 2, is respectively arranged with brace panel 6 between left trailing arm 1, right trailing arm 3 and crossbeam 2, and the two ends of crossbeam 2 are welded on left trailing arm 1, the right trailing arm 3 by brace panel 6.
As shown in Figure 3, brace panel 6 cross sectional shapes are similar to the end surface shape of crossbeam 2, but end face greater than crossbeam 2, therefore brace panel 6 obviously increases than fusion length in the existing design and bonding area with the weld seam of left trailing arm 1 and right trailing arm 3, strengthened intensity, particularly torsional strength is significantly strengthened.
The thickness of described simultaneously brace panel 6 is set to the section thickness greater than the trailing arm upper body 5 of left trailing arm 1 and right trailing arm 3, thereby can reduce the distortion that produces in welding effectively.
As shown in Figure 2, left side trailing arm 1 and right trailing arm 3 are combined by trailing arm upper body 5 and cover plate 4, and trailing arm upper body 5 and cover plate 4 are that three side sealing closes for cross-sectional plane, the U-shaped of an opening, and with the U-shaped opening of trailing arm upper body 5 towards homonymy wheel direction, promptly towards the outside of car body.Brace panel 6 is welded in parallel on the U-shaped bottom surface of described trailing arm upper body 6, changed the structure on the side plate of the U-shaped structure that in the existing structure crossbeam 2 is welded direct to trailing arm upper body 5, therefore when being welded to brace panel 6 on the trailing arm upper body 5, because trailing arm upper body 6 is a symmetrical structure, reduced the distortion of trailing arm upper body 6 effectively, the internal stress of generation is less.
