Abstract
The invention discloses a processing method of an outer coupling sleeve assembly for a car damper. The method is that an outer coupling sleeve assembly comprises an outer coupling sleeve, an inner coupling sleeve and a dustproof gasket which are integrally interconnected through damping cushions formed by vulcanization shaping. According to the method, the welding of the inner coupling sleeve and the dustproof gasket in the outer coupling sleeve assembly processing is removed, so that the processing steps are decreased, the welding cost is saved, the phenomena of welding stress, uneven welding and undercutting of welding caused by the welding can be removed; the fatigue-caused failure of the damper under high-strength AC load can be reduced; the use reliability and stability of the damper can be improved; the service life of the damper can be prolonged; the after-sale fault rate of the damper can be effectively reduced.
Description
Technical field
The present invention relates to a kind of processing method, particularly relate to a kind of processing method of vehicle shock absorber external connecting sleeve assembly.
Background technique
As shown in Figure 1, in the design process of shock absorber for vehicle, external connecting sleeve assembly mainly comprises external connecting sleeve 1, damping pad 2, interior joint sleeve 3 and dust washer 4.Wherein the function of interior joint sleeve 3 is: be 1. fixed on connecting rod 6 end face by nut 5, under the transition of damping pad 2, play the transmission of power between vehicle body 7 and vibration damper; 2., in assembly process, prevent rotary action.The function of dust washer 4 is: be 1. installed between bearing 8 and interior joint sleeve 3, increases lifting surface area, makes bearing 8 and damping pad 2 uniform stressed; 2. prevent dust, muddy water enters bearing 8.
As the external connecting sleeve assembly be connected with vehicle body 7, after front vibration damper assembling, its bearing sub-assembly upper-end surface and dust washer interior edge face fit tightly, and external structure nut 5 and interior joint sleeve 3 interior edge face fit tightly.Therefore in requiring, joint sleeve 3, dust washer 4 and stack face thereof are smooth, ensure vibration damper in use bearing 8 uniform stressed and avoid external structure nut 5 to loosen, produce the faults such as abnormal damage.
The processing method of tradition external connecting sleeve assembly is: first connected with dust washer 4 by interior joint sleeve 3, then with external connecting sleeve, the one-body molded external connecting sleeve assembly of damping pad sulfuration.Wherein, interior joint sleeve 3 has projection welding and gas shielded arc welding two kinds of modes, shown in Fig. 2 and Fig. 3 with the connecting mode of dust washer 4.
Above-mentioned interior joint sleeve and dust washer adopt the connecting mode of projection welding or gas shielded arc welding, there is following defect: 1. all can produce welding stress and welding deformation defect after welding; 2. welding process need carry out heating, pressurizeing, and due to by the impact of welding heat affected zone, after welding cooling, welding stress cannot be eliminated, and reduces interior joint sleeve-dust washer assembly fatigue life; 3. the inequality that is stressed in welding process and the rear inhomogeneous cooling impact of welding, easily produce the out-of-flatness of dust washer end face, aggravation bearing sub-assembly weares and teares; 4. in, the out-of-flatness of joint sleeve end face causes unbalance stress after external structure nut screwing clamping, produces microgap so that loosen to cause abnormal sound under alternate load effect powerful for a long time; 5. adopt the connecting mode of gas shielded arc welding, easily occur after welding welding " depression undercut " phenomenon, under the powerful effect of stress in vibration damper using process, first " undercut " place ftractures as splitting source and finally occurs fatigue failure.
Therefore, the direction becoming these those skilled in the art and make great efforts how is solved the problems of the technologies described above.
Summary of the invention
Object of the present invention is just to provide a kind of vehicle shock absorber external connecting sleeve assembly processing method, can solve above-mentioned the deficiencies in the prior art part completely.
Object of the present invention is realized by following technical proposals:
A kind of vehicle shock absorber external connecting sleeve assembly processing method, external connecting sleeve assembly comprises external connecting sleeve, interior joint sleeve and dust washer, and described external connecting sleeve, interior joint sleeve and dust washer are interconnected to constitute an entirety by the damping pad of sulfidization molding.
Further, described external connecting sleeve, interior joint sleeve and dust washer are positioned in die cavity corresponding to vulcanization die, and apply the pressure of 80 ~ 100kg to mould, inject rubber finally by runner to die cavity, and sulfuration forms damping pad.
Further, described interior joint sleeve and dust washer are positioned in die cavity corresponding to vulcanization die, and interior joint sleeve bottom surface and dust washer end face are fitted, faying surface and plane-parallel.
Compared with prior art, beneficial effect of the present invention is: the welding step eliminating joint sleeve and dust washer in the processing of external connecting sleeve assembly, both process step was decreased, save welding cost, turn eliminate the welding stress because welding reason causes, postwelding out-of-flatness and welding " undercut " phenomenon.Reduce the fatigue failure phenomenon of vibration damper in the using process of high strength alternate load, improve vibration damper operational safety and stability, extend the working life of vibration damper, effectively reduce the rate of fault after sale of vibration damper.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art external connecting sleeve assembly;
Fig. 2 is the structural representation that in prior art, joint sleeve is connected with dust washer projection welding;
Fig. 3 is the structural representation that in prior art, joint sleeve is connected with dust washer gas shielded arc welding;
Fig. 4 is the structural representation of the external connecting sleeve assembly utilizing the inventive method machine shaping.
Embodiment
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
See Fig. 4, a kind of vehicle shock absorber external connecting sleeve assembly processing method, external connecting sleeve assembly comprises external connecting sleeve 1, interior joint sleeve 3 and dust washer 4, and described external connecting sleeve 1, interior joint sleeve 3 and dust washer 4 are interconnected to constitute an entirety by the damping pad 2 of sulfidization molding.
Concrete processing molding method is as follows: be first positioned in die cavity corresponding to vulcanization die by described external connecting sleeve 1, interior joint sleeve 3 and dust washer 4, in ensureing, joint sleeve 3 bottom surface and dust washer 4 end face are fitted, and faying surface and plane-parallel, then mould is applied to the pressure of 80 ~ 100kg, rubber is injected to die cavity finally by runner, sulfuration forms damping pad 2, utilize the adhesive property of rubber by bonding as a whole to interior joint sleeve 3, dust washer 4, external connecting sleeve 1, form external connecting sleeve assembly.
In the using process of vibration damper, interior joint sleeve 3 and dust washer 4 are without relative movement.Present invention eliminates the welding step of joint sleeve and dust washer in the processing of external connecting sleeve assembly, in damping pad sulfidization molding process, utilize the adhesive property of rubber to make interior joint sleeve, dust washer, external connecting sleeve be connected to form an entirety, both process step was decreased, save welding cost, turn eliminate the welding stress because welding reason causes, postwelding out-of-flatness and welding " undercut " phenomenon.Reduce the fatigue failure phenomenon of vibration damper in the using process of high strength alternate load, improve vibration damper operational safety and stability, extend the working life of vibration damper, effectively reduce the rate of fault after sale of vibration damper.
