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 its use that matches with 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, and follow-up is will filter the regulator assembly to reduce the situations such as cost and manufacture cycle, has carried out Test of Home to filtering the regulator assembly.Present case is: occurred the higher hidden danger of quality of failure rate in process of the test, the Market Feedback failure rate is higher, main manifestations is to leak air for the problem of the filtration regulator assembly of production domesticization, reach 10700PPM so that filter regulator assembly failure rate, 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 continue to use import to filter the regulator assembly then cause the manufacture cycle long, expensive so that cost is high.As seen, filter the problem of regulator assembly, become the restriction bottleneck of automobile gearbox industry.
Summary of the invention
The technical problem that solves
For fear of the deficiencies in the prior art part, 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; Characterized by further 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 large cylindrical endoporus oral area at valve body 11 hyperbaric chambers and low-pressure cavity two ends is screw, and the cylindrical endoporus at air outlet hole two ends is Screw hole structure, and an end screws in plug screw 9 and carries out fastening; Air inlet position is made screw; Then 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; In the screw of valve body 11 low-pressure cavity, embed successively piston 8 and B spring 12, then by being threaded into spring cup 13 and tightening cover 14; Embed respectively A O type circle 2 and B O type circle 3 in the ring shaped slot of described bottom 1; Embed C O type circle 10 on the described piston 8.
Coating silicone grease on described A O type circle 2 and the B O type circle 3.
Scribble sealer on the described plug screw 9.
Beneficial effect
A kind of filtration regulator assembly that the present invention proposes, domestic filtration regulator assembly structure design has been carried out repeatedly optimizing, respectively from rubber seal, the cleanliness control aspect of the 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, simplified the loaded down with trivial details of the difficulty of processing body cavity physical dimension and assembly process and avoided the thimble dislocation by the piston guide location, 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.By 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.
