The connecting structure is characterized in that: the two flange heads (7) are connected with two ends of the sleeve (10) by welding, the radial fit of the flange head (7) and the sleeve (10) is clearance fit, and the fit clearance is 0.05 +/- 0.02 millimeter; the axial fit length of the flange head (7) and the sleeve (10) is 1/3 to 1/2 pipe diameter of the sleeve (10); after the flange head (7) and the sleeve (10) are axially positioned, the shortest distance L between the end face of the sleeve (10) and the end face of the flange head (7) is 6 to 10 millimeter; and the end face of the sleeve (10) is welded with an inner hole of the flange head (7) by adopting ring welding, and the height of a weld joint is 4 to 5 millimeters. Through CAE analysis and calculation and bench test, the CAE calculation result is quite approximate to the test value, the stress distribution rule is consistent with the test, and the bench test result accords with national standards of QC/T533-1999 and QC/T534-1999.
Description
Technical field
The invention belongs to auto parts and components structure design field, relate to a kind of connection structure of automotive driven rear axle housing assembly.
Background technology
In some MPV and even car, its driven rear axle housing assembly often adopts the semi-independent suspension frame structure of torsion beam type.Though the relative front suspension of this version, especially Mike Fu Xunshi suspension is fairly simple, installation location on car body is also convenient, but compare with traditional integral type driven rear axle housing assembly, no matter from analyze, design, still in manufacturing, the checking, its complexity is self-evident, and cost is also higher.
Fig. 1 is the semi-independent suspension frame structure of torsion beam type, and its basic structure is made up of bushing pipe 1, torsion bar 2, trailing arm 3, collar head 4, helical spring seat 5, crossbeam 6.Adopt between each part to be welded to connect, the collar head end face has the requirement of positive toe-in, negative camber angle.From Fig. 1, we are not difficult to find out: the parts of shaping such as trailing arm 3, helical spring seat 5 and crossbeam 6 require relatively all higher at oad; Integrally-built design, analysis and checking; The assurance of the positive toe-in of collar head end face, negative camber angle and weld strength.These factors all affect the cost of the semi-independent suspension frame structure of torsion beam type.For in the commercial vehicle/comm..vehicle of shelves on the low side, the pressure of cost just seems and has been even more important.Therefore, the enterprise of the driven rear axle housing assembly of the semi-independent suspension frame structure of China's torsion beam type is also few, and this is that not only its design, validation difficulty are big, the more important thing is to be that it has high input that it is not high to make added value.
Summary of the invention
The object of the present invention is to provide a kind of connection structure of automotive driven rear axle housing assembly.
The present invention is achieved in that it comprises collar head, spring perch, shock absorber support and sleeve pipe, collar head, spring perch, shock absorber support are connected with sleeve pipe, sleeve pipe is the body of rear axle housing assembly, the termination, two ends of two collar heads and sleeve pipe is welded to connect, collar head and sleeve pipe radial fit are free-running fit, and tolerance clearance is 0.05 ± 0.02mm; Collar head and quill drive are 1/3～1/2 of sleeve pipe caliber to length of fit; After collar head and the sleeve pipe axial location, box face and collar head end face shortest distance L are 6～10mm; Box face and collar head endoporus adopt boxing welding, weld bead height 4～5mm.
The design's invention is calculated and the stand test checking through cae analysis, and CAE result of calculation and trial value are very approaching, and stress distribution law is consistent with test, and rig test result meets national QC/T533-1999, QC/T534-1999 standard.
