Abstract

The utility model discloses an automobile part and particularly provides an automobile torsion beam. A toe-in and a camber angle of the automobile torsion beam can be corrected after welding and assembly are finished. The automobile torsion beam comprises a torsion beam body, a longitudinal arm, a spring seat and a tyre support, wherein the longitudinal arm is installed at the end portion of the torsion beam body, the tyre support is installed on the longitudinal arm, and the spring seat is installed on the torsion beam body and the longitudinal arm. The automobile torsion beam further comprises a drum installing plate, wherein the drum installing plate is welded on the tyre support and provided with a tyre connecting hole, and the tyre connecting hole is matched with a tyre installing hole on the tyre support. Due to the fact that the automobile torsion beam is provided with the drum installing plate, after the tyre support is welded, the toe-in and the camber angle can be adjusted by milling the drum installing plate, the installing accuracy of the whole automobile torsion beam is high, tyre abrasion caused by the installing accuracy problem is avoided, and the whole drum installing plate is simple in structure and low in cost.

Description

The automobile torsion beam
Technical field
The utility model relates to a kind of automobile component, especially a kind of automobile torsion beam.
Background technology
The semi-independent suspension of torsion beam is rear overhang hanging hang structure commonly used at present, V-arrangement by an integral body or the torsion beam of channel section are the trailing arm solder together of the left and right sides, be connected than formula with the vehicle body work by rubber-metal support at the front end of trailing arm, link to each other at rear end and wheel hub, bumper and the spring of trailing arm.The trailing arm of torsion beam can swing up and down so that by bumper and damping spring absorbing vibration around rigid point of connection, play the effect of shock-absorbing, when both sides suspension distortion does not wait, the torsion beam distortion that twists, because this torsion beam has bigger elasticity, can play the effect of stabilizer antiroll bar.Therefore torsion beam is critical component in the semi-independent suspension of torsion girder-like, and it plays power transmission, stressed and the effect that is connected the balance both sides, and suspension is related to vehicle performance and traveling comfort.Because tire support is welded on above the trailing arm, causes welding deformation easily, can't guarantee correct toe-in and camber angle, thereby cause wear on tyres serious, influences the handling stability of car load.
The utility model content
Technical problem to be solved in the utility model provides a kind of automobile torsion beam that can revise prenex and camber angle behind welding assembly.
The automobile torsion beam that its technical matters that solves the utility model adopts, comprise torsion beam, trailing arm, spring perch and tire support, described trailing arm is installed in the end of described torsion beam, described tire support is installed on the described trailing arm, described spring perch is installed on torsion beam and the trailing arm, also comprise bulging adapter plate, described bulging adapter plate is welded on the described tire support, offer the tire connecting bore on the described bulging adapter plate, the tire mounting hole on described tire connecting bore and the described tire support mates mutually.
Further be, described tire support is provided with knock hole, and described bulging adapter plate is provided with the fix shaft that is complementary with described knock hole.
Further be that the bottom of described spring perch is provided with spring spline block.
The beneficial effects of the utility model are: owing to be provided with bulging adapter plate, therefore after tire support welds, can adjust toe-in and camber angle by milling bulging adapter plate, so just make that the setting accuracy of whole automobile torsion beam is higher, avoided the wear on tyres that causes because of the setting accuracy problem, and whole bulging mounting plates structure is simple, and is with low cost.On tire support and drum adapter plate, can adopt location structure, make things convenient for both when being welded to each other connection, to locate mutually, improve installation effectiveness.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the scheme drawing of tire support and drum adapter plate;
Parts, position and numbering among the figure: torsion beam 1, trailing arm 2, spring perch 3, tire support 4, drum adapter plate 5.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises torsion beam 1, trailing arm 2, spring perch 3 and tire support 4, described trailing arm 2 is installed in the end of described torsion beam 1, described tire support 4 is installed on the described trailing arm 2, described spring perch 3 is installed on torsion beam 1 and the trailing arm 2, also comprise bulging adapter plate 5, described bulging adapter plate 5 is welded on the described tire support 4, offer the tire connecting bore on the described bulging adapter plate 5, the tire mounting hole on described tire connecting bore and the described tire support 4 mates mutually.Drum adapter plate 5 at first is welded on the tire support 4, and then tire support 4 is welded on the trailing arm 2, because the influence that welding is shunk, tire support 4 will inevitably be out of shape, can guarantee angle of toein and the camber angle of suspension this moment by milling bulging adapter plate 5, just rouse adapter plate 5 and provide certain stock left for machining for tire support 4, can after welding, repair.So just can guarantee correct toe-in and camber angle accurately.
For fast speed location tire support 4 and drum adapter plate 5, described tire support 4 is provided with knock hole, and described bulging adapter plate 5 is provided with the fix shaft that is complementary with described knock hole.Knock hole and fix shaft generally arrange two respectively, namely form two pairs of location structures, the shape of two knock holees and or in different size, fix shaft and its corresponding positioning hole shape and size are complementary, and so just can locate fast and accurately.
For the ease of mounting spring, the bottom of described spring perch 3 is provided with spring spline block.Like this, when spring perch 3 mounting spring, the spline block just can prevent that spring from rotating, and made things convenient for the spring installation.
