The above and below of above-mentioned C ellbeam interlude is welded pasting board and following pasting board respectively, and last pasting board and first part are installed with corresponding dowel hole;
Above-mentioned C ellbeam interlude is provided with sleeve pipe, and its sleeve pipe is worn to pasting board is also affixed down from last pasting board.
Above-mentioned C ellbeam both ends welding shock absorber adapter plate.
Above-mentioned C ellbeam both ends welding air bellow adapter plate.
The inboard middle front part position of above-mentioned C ellbeam has the axis hole of the straight propelling rod axle of dress weldering.
The utility model is compared with existing conventional art, has following beneficial effect:
A, upper and lower half part of the utility model C ellbeam all adopt the constant strength beam form, are shaped with same die stamping, and C ellbeam cross-sectional plane is " saying " font, and by dowel hole with the sleeve pipe location and be connected.Removed additional reinforcement and composition backing in upper and lower half part, simple in structure, in light weight, single-piece 98Kg satisfying weight-saving simultaneously, has guaranteed enough intensity and installing and locating precision, and has further improved the manufacturability requirement of batch manufacturing.The interlude and the bridging of C ellbeam connect, and for improving intensity, the upper and lower weldering pasting board that adds, last pasting board are processed with high-precision dowel hole to guarantee setting accuracy, see Fig. 4.When suspension was installed, straight bolt or saddle clamp passed 4 branch casings, and sleeve pipe plays guiding and the effect of gaining in strength, and top and bottom produce indent and lock not tight when avoiding bolted.After last pasting board and C ellbeam last slice and the sleeve pipe welding, plane in the processing, the processing dowel hole, processing cover pipe orifice is to guarantee the setting accuracy of whole suspension.
B, low cost of manufacture.
I, upper and lower half part of same mould punching are saved the very high large-scale punch die of a cover cost.
Ii, press upper and lower half part of constant strength beam design-calculated, height is reduced toward two ends gradually by middle, compares with common contour blanked part, and stock utilization improves greatly, saves material.
Iii, supreme, lower liner are strengthened blanked part and composition backing.
C, production technology are good.
I, upper and lower half part punching process character are good: degree of uprising is compared with the blanked part of equal altitudes, and the press depth of sweep reduces, and is beneficial to drawing, is not easy to crack and gauffer.
Ii, install good to neutrality: all with location, Sheet Metal Forming Technology hole, and upper and lower half part was again same mould punching, is easy to centering when upper and lower half part was installed, and upper and lower half part profile can fit like a glove good looking appearance.
Iii, cross wall play important effect to preventing C ellbeam welding deformation, and upper and lower half part butt weld is straight, even, is easy to guarantee welding quality.
Dress weldering straight propelling rod in the inboard middle front part position of C ellbeam is with axle, and axis hole is in sheet and the cross wall welding back processing up and down of C ellbeam; Front and back dress weldering air bellow lower installation board, bumper adapter plate are to carry the suspension related components.
The finite element analysis of C ellbeam assembly design process repeated use is optimized design, and the C ellbeam assembly that completes carries out reliability test by actual working environment, has guaranteed that the C ellbeam does not take place to destroy or plastic deformation in car load life-cycle process.
The utility model C ellbeam has satisfied lightweight, low cost, high strength, high installing and locating precision, low installation and maintenance difficulty simultaneously, has been fit to produce in enormous quantities the manufacturability requirement.Applicable to self-propelled vehicle drive axle four gasbags air suspension.
