Abstract
The utility model discloses a rear torsion beam hub support structure. The rear torsion beam hub support structure comprises a hub support assembly and a longitudinal arm, wherein the hub support assembly and the longitudinal arm are welded in a plane attachment mode, and the hub support assembly is provided with a threaded installation hole used to be connected with a rear hub unit. By means of the structure, the rear torsion beam hub support structure is capable of guaranteeing the welding gap between a hub support and the longitudinal arm, the uniformity of welding deformation and the welding quality of weld beads.
Description
Technical field
The utility model relates to the vehicular spare parts technical field, especially relates to a kind of rear torsion beam wheel hub supporting structure.
Background technology
In present car assembling structure, the wheel hub holder 11 of most retrotorsion beam type back axle is that cambered surface cooperates when welding with trailing arm 12, Fig. 1 is the structural representation of original rear torsion beam wheel hub supporting structure, as shown in the figure, the two installs rear-wheel hub unit assembly by hold-down bolt and nut, this kind connection mode is because the impact of the possibility resilience of trailing arm forming elbow and the resilience of blanked part distortion possibility, welded gaps is inconsistent when causing rear torsion beam wheel hub holder and trailing arm welding, and then cause rear torsion beam welding assembly four-wheel difficult parameters with control, and affect the welding quality of this position welding bead.
Summary of the invention
The purpose of this utility model provides a kind of rear torsion beam wheel hub supporting structure, can guarantee to take turns the welded gaps of hub holder and trailing arm, guarantees the welding quality of welding deformation conformability and welding bead.
For achieving the above object, the utility model provides a kind of rear torsion beam wheel hub supporting structure, comprises wheel hub bracket assembly and trailing arm, and described wheel hub bracket assembly and described trailing arm are by the welding of plane laminating type.
Preferably, described wheel hub bracket assembly is provided with for the threaded mounting hole that connects the rear-wheel hub unit.
Therefore, the utility model adopts the rear torsion beam wheel hub supporting structure of said structure, can guarantee to take turns the welded gaps of hub holder and trailing arm, guarantees the welding quality of welding deformation conformability and welding bead.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of original rear torsion beam wheel hub supporting structure;
Fig. 2 is the structural representation of the utility model rear torsion beam wheel hub supporting structure embodiment;
Fig. 3 is the joint face structural representation of wheel hub bracket assembly described in the utility model rear torsion beam wheel hub supporting structure embodiment and described trailing arm.
The specific embodiment
Embodiment
Fig. 2 is the structural representation of the utility model rear torsion beam wheel hub supporting structure embodiment, as shown in Figure 2, comprises wheel hub bracket assembly 21 and trailing arm 22, and wheel hub bracket assembly 1 and trailing arm 2 are by the welding of plane laminating type.The utility model cooperates welding by wheel hub bracket assembly 21 is cooperated welding change to simple plane with the complicated cambered surface of trailing arm 22, thereby guaranteed welded gaps between the two, eliminate the impact of the possibility resilience of trailing arm forming elbow and the resilience of blanked part distortion possibility, and then guaranteed welding conformability and welding bead quality.
In original rear torsion beam wheel hub supporting structure, owing to needing brake forming, select sheet material thinner, when being that therefore the rear-wheel hub unit connects, need to set up rear-wheel hub cellular installation nut 13, as shown in Figure 3.And in the present embodiment, because the utility model wheel hub holder does not have brake forming, can adopt than heavy-gauge sheeting and process, therefore cancelled rear-wheel hub cellular installation nut, wheel hub bracket assembly 21 is provided with for the threaded mounting hole 23 that connects the rear-wheel hub unit, realize the installation of rear-wheel hub unit by tapping on mounting hole, so that wheel hub bracket assembly 21 and trailing arm 22 gaps are less, the gap with trailing arm behind the assurance rear-wheel hub cellular installation meets the demands.
Therefore, the utility model adopts the rear torsion beam wheel hub supporting structure of said structure, can guarantee to take turns the welded gaps of hub holder and trailing arm, guarantees the welding quality of welding deformation conformability and welding bead.
It should be noted that at last: above embodiment is only in order to the technical solution of the utility model to be described but not limit it, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment or be equal to replacement the technical solution of the utility model, and these modifications or be equal to replacement and also can not make amended technical scheme break away from the spirit and scope of technical solutions of the utility model.
