Description
Technical field
The utility model relates to vehicle shock absorber, particularly the air-bag shock absorber surge drum assembly on the vibration damper.
Background technique
Air-bag shock absorber is the main direction of loaded vehicle operator cabin vibration damper development, and the surge drum assembly of air-bag shock absorber is the important composition part of vibration damper, and it provides functions such as store oil, support frame, pressure bladder for vibration damper.
As a rule the surge drum assembly of air-bag shock absorber comprises parts such as the surge drum sub-assembly of air-bag shock absorber and ring washer 13, steel wire collar 16, suspension ring 15, and wherein the surge drum sub-assembly of air-bag shock absorber comprises surge drum 11 and bottom 14, as shown in Figure 1.The effect of above-mentioned each parts is as follows:
Surge drum 11: in vibration damper, play store oil, support frame, pressure bladder;
Bottom 14: in vibration damper, play location clutch release slave cylinder, sealing fluid;
Back-up ring 13: the restriction air bag moves axially in vibration damper, plays the axially locating effect;
Steel wire collar 16: fixing back-up ring in vibration damper, play the axially locating effect;
Suspension ring 15: in vibration damper, work the vehicle frame effect that connects.
Above-mentioned parts are assembled together and constitute air-bag shock absorber surge drum assembly, are assembled together with air bag, play support air bag, the store oil function; Suspension ring and automobile chassis link.
Working principle: surge drum assembly, connecting rod sub-assembly and air bag form vibration damper complement, and during vibration damper complement work, the gas in air bag reaches certain pressure, and surge drum assembly and air bag cooperation place form sealing, and the gas in the air bag is not leaked.
The air bag axial limiting is finished by back-up ring and steel wire collar combination, and will guarantee the assembling of steel wire collar on the surge drum assembly, must cut arc groove earlier on bottom, has so just increased the difficulty of processing of bottom; The assembling of back-up ring and surge drum is a Spielpassung, back-up ring is in loosening state all the time, product surface is handled the back and is existed fraction not have the position of baking vanish all the time on the surge drum surface, and the position that does not have baking vanish is in air bag assembling position, easily corrosion and produce gas leakage causes that vibration damper complement lost efficacy in the product using process.
The welding manner of original surge drum and bottom adopts the CO2 gas shielded arc welding usually, the big damage easily of spatter surge drum surface, air bag gas leakage when causing the later stage to assemble.The high higher machining (grinding) that is unfavorable for the later stage of weld seam heap must be cut after the welding in advanced driving in addition, weld seam is piled high part turning fall, and carries out grinding again.
Working properly in stretching, extension and compression movement process in order to guarantee air bag, the sealing position of air bag and surge drum requires very high, the sealing position adopts the O RunddichtringO to seal, so size, the accuracy of form and position and surface roughness to surge drum are had relatively high expectations, in case because the quality problems on surge drum surface cause air bag gas leakage, will cause the vibration damper complement cisco unity malfunction, cause product failure
The model utility content
The purpose of this utility model is: at the deficiencies in the prior art, provide a kind of and reliable, the easy to process air-bag shock absorber surge drum assembly of air sac sealing.
The technical solution of the utility model is:
A kind of air-bag shock absorber surge drum assembly, comprise surge drum, be fixed on the surge drum bottom and with the suspension ring that bottom is assembled together, it is characterized in that: on the surge drum outer wall, be fixed with ring washer.
Supplementary technology scheme of the present utility model is as follows:
Preferably, ring washer is fixed on an end of close bottom on the surge drum outer wall.
Preferably, ring washer is welded on the surge drum outer wall.
Preferably, bottom and surge drum are weldingly fixed on together by argon arc welding.
Preferably, surge drum has one section grinding face section by an end of bottom, and the diameter of grinding face section is greater than other section diameters of surge drum, and the axial length of grinding face section is less than 40% of surge drum length, and ring washer is fixed on the grinding face section.
The beneficial effects of the utility model are: back-up ring directly is fixedly welded on the surge drum, and intensity is greatly improved, and has reduced the difficulty of bottom processing, can not occur having improved the quality of product because of the loosening phenomenon that causes the surge drum surface corrosion of back-up ring.Adopt argon arc welding, it is higher that nothing is welded the face of weld quality of splashing, and to the not influence of machining (grinding) in later stage, directly carries out grinding after the welding, saved manufacturing procedure than the original structure ratio.Shorter grinding face has reduced and caused colliding with and scratching of surge drum external diameter (air bag mating face) in turnover, has guaranteed the quality state of product.The production routine of whole work-piece is simplified, and cost reduces, and has improved quality.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the schematic representation of prior art air-bag shock absorber surge drum assembly.
Fig. 2 is the utility model air-bag shock absorber surge drum assembly embodiment's a schematic representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model, as shown in Figure 2, a kind of air-bag shock absorber surge drum assembly, the suspension ring 25 that comprise surge drum 21, are fixed on the bottom 24 on the surge drum 21 and are assembled together with bottom 24, the air bag axial limiting is independently finished by back-up ring 24, back-up ring 24 directly is welded on the surge drum 21, the intensity of the two combination is greatly improved, and reduced the difficulty of bottom 24 processing, can not occur having improved the quality of product because of the back-up ring 23 loosening phenomenons that cause surge drum 21 surface corrosions.
In order further to save operation, surge drum 21 can adopt argon arc welding with the welding manner of bottom 24, and it is higher that nothing is welded the face of weld quality of splashing, to the not influence of machining (grinding) in later stage, directly carry out grinding after the welding, saved manufacturing procedure than the original structure ratio.
The further improvement of this embodiment scheme, surge drum 21 has one section grinding face section 22 by an end of bottom 24, the diameter of grinding face section 22 is greater than other section diameters of surge drum 21, and the axial length of grinding face section 22 is less than 40% of surge drum 21 length, and ring washer 23 is fixed on the grinding face section 22.The processing sequence of this scheme surge drum assembly: enlarging------argon arc welding---grinding external diameter (grinding face is shorter)---welding back-up ring---welding hanging ring that press-fits bottom; Simplified process route, improved work efficiency, particularly brief grinding face has reduced and caused colliding with and scratching of surge drum external diameter (air bag mating face) in turnover, has guaranteed the quality state of product.
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing), unless special narration, all can be replaced by other equivalences or the alternative features with similar purpose. promptly, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
