Abstract
The utility model discloses a torsion bar beam rear axle which comprises a beam, suspension arms and lining sleeves. The suspension arms are fixed at two ends of the beam, one lining sleeve is fixed at one end of each suspension arm and is straight tubular, each suspension arm is bent tubular and comprises a front end pipe and a rear end pipe, a circular arc profile surface is formed at each end of the front end pipe and matched with the outer wall of the corresponding lining sleeve, each profile surface contacts with the outer wall of the corresponding lining sleeve to form a welding seam, the lining sleeves and the suspension arms are fixedly welded, and the central axis of each front end pipe is perpendicular to that of the corresponding lining sleeve. Therefore, the welding seam formed between each lining sleeve and the corresponding suspension arm is a simple circular arc, so that the welding seams are decreased as compared with a seam in the prior art, and welding quality is improved.

Technical field
The utility model relates to the automotive axle structure technology, relates in particular to a kind of torsion bar beam back axle.
Background technology
Back axle refers to the rear drive shaft component part that vehicle power transmits, and torsion bar beam back axle is a kind of of back axle, and as shown in Figure 1, it mainly comprises crossbeam 1, suspension arm 2 ' and lining pipe 3 etc.Suspension arm 2 ' quantity be two, be tubulose, be weldingly fixed on the two ends of crossbeam 1, lining pipe 3 be weldingly fixed on suspension arm 2 ' an end.
As shown in Figures 2 and 3, lining pipe 3 is hollow tube, in order to be complementary with lining pipe 3, need suspension arm 2 ' the certain contoured surface of end punch forming, and lining pipe 3 for the cooperating of other parts, the central axis that lining pipe 3 central axis and suspension arm are set usually has the off plumb angle, makes the contoured surface of the outside wall surface of lining pipe 3 and suspension arm 2 ' end form the shape of oval intersection, the position of this intersection form reserve weld seam 4 '.But, because the precision of Sheet Metal Forming Technology is not enough, cause between the outside wall surface of the contoured surface of suspension arm 2 ' end and lining pipe 3 gap bigger, influence the welding quality of welding robot.Simultaneously, lining pipe 3 central axis and suspension arm 2 ' central axis have the off plumb angle, caused the reservation weld seam 4 of the two touching position both sides ' be uneven in length, notch effect appears then, produce stress and concentrate, finally cause back axle to lose efficacy.
The utility model content
The utility model provides a kind of torsion bar beam back axle, to solve the problems of the prior art, improves the weld seam quality of connection between torsion bar beam back axle upper suspension arm and the lining pipe.
The utility model provides a kind of torsion bar beam back axle, comprises crossbeam, suspension arm and lining pipe, and described suspension arm is fixed on the two ends of described crossbeam, and described lining pipe is straight tube-like, and described lining pipe is fixed on an end of described suspension arm, wherein:
Described suspension arm comprises front tube and rear end pipe for the bending tubulose; The front tube end of described suspension arm is formed with circular-arc contoured surface, and the outside wall surface of described contoured surface and described lining pipe is complementary;
The described contoured surface formation weld seam that contacts with the outer wall of described lining pipe, by welding fixing described lining pipe and described suspension arm, the central axis of described front tube and the center shaft of described lining pipe are to mutual vertical.
Aforesaid torsion bar beam back axle, wherein, preferably: more than the external diameter 10mm of the length of described weld seam greater than described lining pipe.
Aforesaid torsion bar beam back axle, wherein, preferably: described lining pipe and described suspension arm are hollow tube.
Aforesaid torsion bar beam back axle, wherein, preferably: described torsion bar beam back axle also comprises spring holder, described spring holder is fixing with described crossbeam and the welding of described suspension arm respectively.
Aforesaid torsion bar beam back axle, wherein, preferably: described torsion bar beam back axle also comprises damper bracket, described damper bracket is fixing with described spring holder and the welding of described suspension arm respectively.
The central axis of the front tube of the torsion bar beam back axle that the utility model provides by suspension arm is set is vertical mutually with the central axis of lining pipe, make the weld seam that forms between lining pipe and the suspension arm for simply circular-arc, and then the punch forming process that the makes suspension arm end profile face simplification that becomes, punching precision is also more high, the slit more of the prior art, slit of weld seam is reduced to some extent, improved the quality of welding.

The specific embodiment
The structural representation of the torsion bar beam back axle that Fig. 4 provides for the utility model embodiment, Fig. 5 is the front tube of suspension arm among the utility model embodiment and the annexation scheme drawing of lining pipe, the weld seam scheme drawing that forms between the contoured surface that Fig. 6 forms for the front tube end of suspension arm among the utility model embodiment and the lining pipe outer wall.To shown in Figure 6, the utility model embodiment provides a kind of torsion bar beam back axle, comprises crossbeam 1, suspension arm 2 and lining pipe 3 as Fig. 4.
Wherein, crossbeam 1 is identical with the beam structure of torsion bar beam back axle of the prior art, and all as the main support of whole back axle, the quantity of suspension arm 2 is two, is weldingly fixed on the two ends of crossbeam 1 respectively.
The central axis that front tube is set is vertical mutually with the central axis of lining pipe, make the weld seam that forms between lining pipe and the suspension arm for simply circular-arc, and in the prior art, the intersection of the two generation then is oval, therefore, the simplification of bead shape makes the simplification that becomes of the punch forming process of the front tube end profile face of suspension arm, thereby punching precision is also more high, the slit more of the prior art, slit of weld seam is reduced to some extent, improved the quality of welding.Simultaneously, the central axis of front tube is vertical mutually with the central axis of lining pipe, can make the fusion length unanimity of suspension arm both sides, and the stressed of weld seam evenly avoided notch effect, has reduced the phenomenon that stress is concentrated.
