Description
Technical field
The present invention relates to a kind of filtration regulator assembly, belong to field of machining.
Background technique
Filtering the regulator assembly is a kind of air reducing valve with filtration, be installed on the heavy duty automobile gear box, and it and the use that matches of mechanically controlled valve, odd-side cylinder assembly, the dependence air valve is realized the switching of high and low shift.Implementation process is: source of the gas offers the stable clean compressed air of mechanically controlled valve through filtering filtration, adjusting, the decompression of regulator assembly on the heavy-duty car.The stroke of mechanically controlled valve push rod changes, and control its station conversion and fill or exhaust, thereby the conversion of air pressure mouth impels the scope shelves declutch shift shaft of odd-side cylinder assembly to carry out expanding-contracting action, realizes the height gear switch of Synchromous device of gearbox.
What the automobile gearbox initial stage adopted is that the regulator assembly is filtered in import, follow-up for will filtering that the regulator assembly reduces cost and situation such as manufacture cycle, has carried out production domesticization and tests filtering the regulator assembly.Present case is: the higher hidden danger of quality of failure rate in process of the test, occurred; The Market Feedback failure rate is higher; The problem that mainly shows as the filtration regulator assembly of production domesticization is to leak air; Make that filtering regulator assembly failure rate reaches 10700PPM, the low 2000PPM of failure rate that filters the regulator assembly with import compares, and the failure rate of the filtration regulator assembly of production domesticization is too high.But if continuation is used import to filter the regulator assembly then caused the manufacture cycle long, costing an arm and a leg makes cost high.It is thus clear that the problem of filtering the regulator assembly has become the restriction bottleneck of automobile gearbox industry.
Summary of the invention
The technical problem that solves
For fear of the deficiency of existing technology, the present invention proposes a kind of filtration regulator assembly.
Technological scheme
A kind of filtration regulator assembly comprises bottom 1, A O type circle 2, B O type circle 3, plug screw 9, C number 0 type circle 10, valve body 11, tightening cover 14 and Cock screw 15; It is characterized in that also comprising filter core 4, spring planet 5, A spring 6, valve 7, piston 8, valve body 11, B spring 12 and spring cup 13; The big cylindrical endoporus oral area at valve body 11 hyperbaric chambers and low pressure chamber two ends is a screw, and the cylindrical endoporus at air outlet hole two ends is a Screw hole structure, and an end screws in plug screw 9 and carries out fastening; Air inlet position is processed screw; Pack into successively at the screw place of valve body 11 hyperbaric chambers one end valve 7, A spring 6, spring planet 5 and filter core 4 screw in bottom 1 then; In the screw of valve body 11 low pressure chamber, embed piston 8 and B spring 12 successively, then through being threaded into spring cup 13 and tightening cover 14; Embed A O type circle 2 and B O type circle 3 in the ring shaped slot of said bottom 1 respectively; Embed C O type circle 10 on the said piston 8.
Coating silicone grease on said A O type circle 2 and the B O type circle 3.
Scribble sealer on the said plug screw 9.
Beneficial effect
A kind of filtration regulator assembly that the present invention proposes; Homemade filtration regulator assembly structure design has been carried out repeatedly optimizing; Respectively from rubber seal; The turbidity test control aspect of links such as pressure spring reliability and the locking of balance pressure element, positioning element rationality, assembling test; Verification experimental verification means and mode have also carried out repeatedly optimizing, and have simplified difficulty and assembly process loaded down with trivial details of processing body cavity physical dimension and have located through piston guide and avoided the thimble dislocation, and the damage gas leak phenomenon is cut on O type circle surface; O type circle sum is compressed to 2 by 3 simultaneously, thereby has reduced the kind quantity of special purpose parts, has reduced manufacture cost.Through improving structure, reduced its assembling complexity, improved that filtration regulator assembly is regulated, decompression reliability and working life, improved the stability of quality of product.

Embodiment
Combine embodiment, accompanying drawing that the present invention is further described at present:
Present embodiment comprises bottom 1, A O type circle 2, B O type circle 3, plug screw 9, C O type circle 10, tightening cover 14 and Cock screw 15; It is characterized in that also comprising filter core 4, spring planet 5, A spring 6, valve 7, piston 8, valve body 11, B spring 12 and spring cup 13.With valve body 11 is main member, valve body likeness in form " ten " word profile.Valve body hyperbaric chamber, low pressure chamber two ends 2-Φ 36 big cylindrical endoporus are processed 2-M30 * 1.5-6H screw, and length differs; Valve body air outlet hole two ends are that the 2-Φ 16 long and short little cylindrical endoporus that differ are processed the 2-NPT1/8 screw, one end are screwed in the plug screw 9 scribble sealer according to purposes till fastening; The NPT3/8 screw is processed at inlet hole endoporus place; Filter adjustment structure place at valve body 11 inner chambers middle part, through hole Φ 6.5 * Φ 4.5 processes the ring packing boss of high 1.0mm.Pack into successively at valve body 11 hyperbaric chamber screw places valve 7, A spring 6, spring planet 5 and filter core 4 screw in bottom 1 then; In valve body 11 low pressure chamber screws, embed piston 8 and B spring 12 successively, then through being threaded into spring cup 13 and tightening cover 14; Embed the A O type circle 2 and B O type circle 3 of coating silicone grease in the ring shaped slot of said bottom 1 respectively; Embed the C O type circle 10 of coating silicone grease on the said piston 8.Begin adjusting, depressurized system, adjustment finishes the fastening Cock screw 15 in back.
This designs simplification processing body cavity physical dimension difficulty and assembly process loaded down with trivial details and locate through piston guide and to have avoided the thimble dislocation, the damage gas leak phenomenon is cut on O type circle surface; The minimizing of O type circle special purpose parts kind quantity simultaneously reduces its complicated and economic processing stage, has reduced manufacture cost.Through improving structure, reduced its assembling complexity, improved that filtration regulator assembly is regulated, decompression reliability and working life, improved the stability of quality of product.Compare with foreign technology, reduced the complexity of assembly technology, the PPM that has guaranteed quality of product and has significantly reduced purchase cost within tolerance interval, avoided the key technology resource 'bottleneck' restrictions of company abroad.
