Abstract
The utility model discloses a suspension, particularly relates to a torsion beam semi-independent suspension and provides the torsion beam semi-independent suspension for improving a spring seat finished product pass rate. The torsion beam semi-independent suspension comprises a beam, a rear shaft body support, a spring seat and a tire support. The rear shaft body support is installed at the end of the beam, the tire support is installed on the rear shaft body support, and the spring seat is installed on the beam and the rear shaft body support and is composed of a flange body and a spring seat lower body which are welded to each other. Due to the fact that the spring seat is composed of the flange body and the spring seat lower body which are of a split type, the flange body and the spring seat lower body are separately subjected to stamping during stamping, a stamping depth is small, cracks do not occur, and accordingly the spring seat finished product pass rate is guaranteed. After a drum mounting plate is additionally installed on the tire support, a toe-in and a camber angle can also be adjusted by polishing the drum mounting plate even if deformation occurs in welding, and influence on operating stability of a whole vehicle is avoided.
Description
Technical field
The utility model relates to a kind of suspension, the semi-independent suspension of especially a kind of 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, make the strand formula at the front end of trailing arm by rubber-metal support and vehicle body and be connected, 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 Panhard rod.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.
Reverse in the semi-independent suspension frame structure whole, the flange on the spring perch and lower body are integral type, cause spring perch to occur crackle easily when punch forming, and this has just influenced the use of spring perch.And tire support is welded on above the trailing arm, causes welding deformation easily, can't guarantee correct toe-in and camber angle, thereby causes 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 semi-independent suspension of torsion beam that improves the spring perch product qualified rate.
The semi-independent suspension of torsion beam that its technical matters that solves the utility model adopts, comprise crossbeam, rear axle body support frame, spring perch and tire support, described rear axle body support frame is installed in the end of described crossbeam, described tire support is installed on the described rear axle body support frame, described spring perch is installed on crossbeam and the rear axle body support frame, and described spring perch is welded to each other by flange body and spring perch lower body to be formed.
Further be, also comprise bulging adapter plate, described bulging adapter plate is welded on the described tire support, offers the tire connecting bore on the described bulging adapter plate, and the tire mounting hole on described tire connecting bore and the described tire support mates mutually.
Further be that the bottom of described flange body is provided with spring spline block.
The beneficial effects of the utility model are: because spring perch is made up of split type flange body and spring perch, therefore flange body and spring perch are to separate punching press when punching press, such press depth is just less, can not make it crackle occur, thereby has guaranteed the product qualified rate of spring perch.After tire support installs bulging adapter plate additional, even welding has produced distortion, also can regulate toe-in and camber angle by the bulging adapter plate of polishing, avoid influencing the handling stability of car load.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the scheme drawing of spring perch;
Fig. 3 is the scheme drawing of tire support;
Parts, position and numbering among the figure: crossbeam 1, rear axle body support frame 2, spring perch 3, tire support 4, flange body 5, spring perch lower body 6, drum adapter plate 7.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises crossbeam 1, rear axle body support frame 2, spring perch 3 and tire support 4, described rear axle body support frame 2 is installed in the end of described crossbeam 1, described tire support 4 is installed on the described rear axle body support frame 2, described spring perch 3 is installed on crossbeam 1 and the rear axle body support frame 2, and described spring perch 3 is welded to each other by flange body 5 and spring perch lower body 6 to be formed.The constituent elements of spring perch 3 all adopts punching press to carry out moulding, flange body 5 and spring perch lower body 6 adopt special diel to carry out moulding respectively, after flange body 5 and 6 punch formings of spring perch lower body, both are welded into spring perch 3, its state is as shown in Figure 2, it should be noted that, weldquality will be got well, and guarantees that intensity can meet the demands, and weldering can not occur leaking, weld seam is inhomogeneous, not full, phenomenons such as burn-through.Because flange body 5 and spring perch lower body 6 are separately stamping forming, so its punching press distance separately is shorter, is not easy to form crackle, has so just guaranteed the yield rate of spring perch 3.
In order to guarantee correct toe-in and camber angle, as shown in Figure 3, also comprise bulging adapter plate 7, described bulging adapter plate 7 is welded on the described tire support 4, offer the tire connecting bore on the described bulging adapter plate 7, the tire mounting hole on described tire connecting bore and the described tire support 4 mates mutually.Drum adapter plate 7 at first is welded on the tire support 4, and then tire support 4 is welded on the rear axle body support frame 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 7, just rouse adapter plate 7 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 the ease of mounting spring, the bottom of described flange body 5 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.Flange body 5 is provided with the welding step of annular, and it is other and concentric with weld seam with the weld seam of spring perch lower body 6 that the welding step is arranged on flange body 5.The welding step can shrink in the adequate compensation welding, improves welding quality.
