The inner lining pipe, the bushing body and the outer lining pipe are respectively of a cylindrical structure. The bushing body is sleeved with the inner lining pipe, the inner lining pipe is in interference fit with the bushing body, and the bushing body is sleeved with the outer lining pipe, and the bushing body is in interference fit with the outer lining pipe. The extrusion-proof structure of the shock absorbing bushing in the truck independent suspension system is characterized in that the length of the inner lining pipe is larger than that of the bushing body, the two ends of the inner lining pipe are both exposed out of the bushing body, the length of the bushing body is larger than that of the outer lining pipe, the two ends of the bushing body are both exposed out of the outer lining pipe, the inner walls at the two ends of the outer lining pipe are respectively provided with a circle of circular bead structure, and the distance between the outer walls at the two ends of the bushing body and the outer wall of the inner lining pipe is larger than the distance between the inner wall of the outer lining pipe and the outer wall of the inner lining pipe. The extrusion-proof structure of the shock absorbing bushing in the truck independent suspension system is reasonable in structural design, the bushing body is difficult to extrude, and the safety performance is high.
Description
Technical field
The utility model relates to a kind of anti-extrusion structure, especially the anti-extrusion structure that relates to shock absorbing bushing in a kind of lorry independent suspension system, be exclusively used in the shock absorbing bushing of lorry independent suspension system, can effectively prevent that the bush body in shock absorbing bushing is forced out, improve the withdrawal force of shock absorbing bushing.
Background technique
Shock absorbing bushing is generally all installed in lorry independent suspension system, conventional shock absorbing bushing comprises internal lining pipe, bush body and outer liner tube at present, internal lining pipe is sleeved in bush body, bush body is sleeved in outer liner tube, the structural design of existing shock absorbing bushing is reasonable not, and not anti-extrusion structure causes the bush body in shock absorbing bushing to be easily extruded out, poor safety performance, has reduced the withdrawal force of shock absorbing bushing.
Model utility content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of reasonable in design is provided, and bush body is difficult to be extruded out, the anti-extrusion structure of shock absorbing bushing in the high lorry independent suspension system of Safety performance.
The technical scheme in the invention for solving the above technical problem is: in this lorry independent suspension system, the anti-extrusion structure of shock absorbing bushing comprises internal lining pipe, bush body and outer liner tube, described internal lining pipe, bush body and outer liner tube are cylinder-like structure, described internal lining pipe is sleeved in bush body, interference fit between this internal lining pipe and bush body; Described bush body is sleeved in outer liner tube, interference fit between this bush body and outer liner tube, and its structural feature is: the length of described internal lining pipe is greater than the length of bush body, the two ends of this internal lining pipe are the exposed outside in bush body all; The length of described bush body is greater than the length of outer liner tube, the two ends of this bush body are the exposed outside at outer liner tube all, the inwall at two of described outer liner tube is provided with a circle fillet structure, and the outer wall at two of described bush body is greater than the inwall of outer liner tube to the distance of the outer wall of internal lining pipe to the distance of the outer wall of internal lining pipe.
As preferably, bush body described in the utility model is polyurethane material.
As preferably, internal lining pipe described in the utility model and outer liner tube are iron material matter.
As preferably, the inner and outer wall at two of internal lining pipe described in the utility model is provided with chamfering structure.
The utility model compared with prior art, have the following advantages and effect: simple in structure, reasonable in design, reliable performance, internal lining pipe and outer liner tube are the through hole shape that two ends are run through, internal lining pipe is embedded in bush body, and with bush body interference fit, then the assembly of internal lining pipe and bush body embeds in outer liner tube again, bush body is squeezed, middle magnitude of interference after being extruded in bush body is to two ends tensile buckling, make the two ends of bush body be greater than the internal diameter of outer liner tube, make bush body be not easy to be forced out, in addition, the very large deformation resistance of extrusion-deformation generation due to bush body, improved the withdrawal force of shock absorbing bushing, make bush body more be difficult for being forced out, improved safety in utilization.
Bush body in the utility model can adopt the manufacture of polyurethane material to form, can there is in wider hardness range higher elasticity and intensity, and excellent wear resistance, oil resistance, fatigue resistance and anti-vibration resistance, thereby greatly promoted the overall performance of lorry independent suspension system.

Embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1 to Fig. 4, in the present embodiment, in lorry independent suspension system, the anti-extrusion structure of shock absorbing bushing comprises internal lining pipe 1, bush body 2 and outer liner tube 3, wherein, internal lining pipe 1, bush body 2 and outer liner tube 3 are cylinder-like structure, and bush body 2 is polyurethane material.
The length of the internal lining pipe 1 in the present embodiment is greater than the length of bush body 2, and the two ends of this internal lining pipe 1 lay respectively at the outside at the two ends of bush body 2, and the two ends of internal lining pipe 1 are all exposed in bush body 2.
The length of the bush body 2 in the present embodiment is greater than the length of outer liner tube 3, and the two ends of this bush body 2 lay respectively at the outside at the two ends of outer liner tube 3, i.e. equal exposed outside at outer liner tube 3, the two ends of bush body 2.The outer wall 21 at two of the bush body 2 in the present embodiment is greater than the inwall 31 of outer liner tube 3 to the distance of the outer wall 11 of internal lining pipe 1 to the distance of the outer wall 11 of internal lining pipe 1, the outer wall 21 at two of bush body 2 is between d1 and d2 to the distance of the outer wall 11 of internal lining pipe 1, and the inwall 31 of outer liner tube 3 is d to the distance of the outer wall 11 of internal lining pipe 1, the length of d and d1's is equal in length, and the two ends of bush body 2 are greater than the centre of bush body 2.This is because bush body 2 is subject to after the extruding of internal lining pipe 1 and outer liner tube 3, and the middle magnitude of interference of extruding is to two ends tensile buckling, makes the two ends of bush body 2 be greater than the centre of bush body 2.
