Technical Field
The invention relates to the field of automobile parts, in particular to a torsion beam longitudinal arm positioning structure.
Background
The torsion beam is a main part of an automobile chassis suspension system, generally comprises a torsion beam welding assembly and 2 automobile body mounting bushings, wherein one end of the torsion beam is connected with an automobile body bracket, and the other end of the torsion beam is connected with a brake disc, so that the assembly size of the whole automobile is influenced, and the torsion beam has a direct relation to the toe-in/camber angle of the whole automobile. At present, the main process of the left/right trailing arm comprises the following steps: stamping or bending molding, wherein in the processing process, process positioning holes and surfaces are not formed, so that the process precision consistency cannot be ensured; meanwhile, the left and right trailing arms can be hydroformed to ensure the product precision, the equipment investment is large, and the processing cost is higher than that of the common processing technology; it becomes important to solve this problem.
Disclosure of Invention
The invention aims to provide a torsion beam longitudinal arm positioning structure, which improves the accuracy by adding positioning surfaces and positioning holes on a left longitudinal arm and a right longitudinal arm, so that the positioning is more accurate and the processing is convenient.
The invention provides a torsion beam longitudinal arm positioning structure which comprises a cross beam, wherein a left longitudinal arm is arranged on the left side of the cross beam, a right longitudinal arm is arranged on the right side of the cross beam, a vehicle body mounting bushing is arranged at the rear end of the left longitudinal arm, a positioning surface is arranged on the lower side of the rear end of the left longitudinal arm, a positioning hole is formed in the middle of the positioning surface, a brake flange is arranged at the front end of the left longitudinal arm, a shock absorber mounting support is arranged on the lower side of the front end of the left longitudinal arm, a spring tray support is arranged between the inner side of the front end of the left longitudinal arm and the cross.
The further improvement lies in that: the left reinforcing plate is arranged at the joint of the front end of the left longitudinal arm and the cross beam, and the right reinforcing plate is arranged at the joint of the front end of the right longitudinal arm and the cross beam.
The further improvement lies in that: the locating surface is a long-strip oval shape, and the locating hole is circular.
The further improvement lies in that: the left longitudinal arm and the right longitudinal arm are welded into a whole, and the left longitudinal arm, the right longitudinal arm and the cross beam are welded into a whole.
The invention has the beneficial effects that: through increasing locating surface and locating hole on left trailing arm and right trailing arm, on the basis that satisfies the singleton and detect, can realize left trailing arm and right trailing arm positioning accuracy, realize turning round the precision of roof beam welding assembly, improve batch production's uniformity and qualification rate, reduce about the not satisfied condition of trailing arm precision, the disposable qualification rate of assembly reduces whole car assembly uniformity.
