Abstract
The utility model discloses a punch diaphragm spring energy-storing brake chamber which is composed of an intermediate body, a large and a small diaphragms, a large and a small clamps, etc. which clamp a vehicle traveling brake chamber. The intermediate body of the punch diaphragm spring energy-storing brake chamber is provided with a guide sleeve bulged into the spring energy-storing brake chamber along a longitudinal shaft line, an intermediate push rod is arranged in the guide hole of the guide sleeve in a sliding way, the annular grooves of both ends of the guiding hole are respectively provided with a sealing ring, the intermediate push rod is connected with a tray through screw threads, one large diaphragm appressed with the radial face of the tray is a diaphragm whose center is punched, and the large diaphragm is fixed by a pressing pad and a lock nut. The utility model has the advantages of tight sealing performance, good guiding performance and stable and reliable work, namely the working stability and reliability of the utility model are obviously improved.
Description
The utility model relates to a kind of membrana perforata chip type spring energy storage brake repair room, and exactly, this spring energy-storage brake repair room is specially adapted to the emergency braking system of compressed air brake autotruck.
The existing pair of diaphragm type spring energy storage brake repair room since its at following aspects, for example do not need to purify source of the gas, good airproof performance, action delay time short, handle synchronism good and given ambient temperature (50 ℃-80 ℃) following can both normal operation etc. the aspect all be better than traditional dual Piston or the piece combined spring energy-storage brake repair room of piston membrane and adopted by China many autotrucies factory.But practice shows, the two diaphragm type spring energy storage brake repair rooms of existing this class part that also comes with some shortcomings, for example the guide section of propelling rod is shorter, seal ring only is set one in the hole of guide section, thereby make its steering capability relatively poor, and add that seal ring easily is worn, cause work in addition reliable and stable inadequately at last, this class spring energy-storage brake repair room all is higher to technological requirement and the dimensional accuracy that reinstalls a spring in it, thereby its cost is also improved thereupon.
Task of the present utility model is, proposes a kind of membrana perforata chip type spring energy storage brake repair room, improves the guide section of its propelling rod from structure, and its working stability and reliability are increased significantly.
Realize that the technical measures that the above-mentioned task of the utility model taked are as described below: the spring energy-storage brake repair room clamps the service brake chamber via an intermediate, big diaphragm, Small diaphragm-piece, big clip and object such as lesser calorie hoop and forms a whole, wherein, intermediate upper edge longitudinal axis is provided with an orienting sleeve that is projected in the spring energy-storage brake repair room, along a middle push rod is housed in the pilot hole of this orienting sleeve slidably; The two ends of pilot hole respectively are provided with an annular groove, and a seal ring then respectively is housed in each annular groove; The right-hand member of middle push rod is fastened on a pallet and is set as in the right-hand member hole of sleeve-like via being threaded, the left end of this pallet then is shaped on outside thread; A big diaphragm being close to the pallet radial face is set as central hole, and fixes by means of a compress gasket and a locknut, and each section and internal and external threads are concentric on the pallet at this moment; A vent as signal port is also set up in the service brake chamber.
Be further elaborated now by means of the embodiment and the principle of work thereof of accompanying drawing to the utility model membrana perforata chip type spring energy storage brake repair room.
Fig. 1 represents a longitudinal cross-section scheme drawing of the utility model membrana perforata chip type spring energy storage brake repair room.
As shown in Figure 1, the utility model membrana perforata chip type spring energy storage brake repair room be through members such as intermediate 15, big diaphragm 16, Small diaphragm-piece 9, big clip 17 and lesser calorie hoops 10 with service brake chamber protecgulum 7 and spring energy-storage brake repair room bonnet 20 pinched composition one, this moment, the length overall of two brake repair rooms was still the same with conventional confguration.Intermediate 15 longitudinally axis is set as the shape of orienting sleeve and is projected into to the right in the interior space of spring energy-storage brake repair room B, along a middle push rod 12 is housed in the pilot hole of this orienting sleeve slidably, because the length of pilot hole is several times as much as conventional confguration, thereby push rod 12 can be done stable in pilot hole and the failure-free slip in the middle of making, that is to say the two ends that make its steering capability greatly improve above-mentioned pilot hole thereby an annular groove can respectively be set, respectively adorn an O RunddichtringO 21 in each annular groove, this structure obviously is very favourable for improving leak tightness, but also help to alleviate degree of wear between member, thereby prolong its service life.In with the left end structure of push rod 12 with traditional the same, for example in the middle of push-plate 5, Small diaphragm-piece 9, push-plate 8 and push rod 2 always abut against together mutually.The right-hand member of middle push rod 12 then is to be fastened on pallet 18 to be set as in the hole of sleeve-like via being threaded, and is that captive joint is integral between push rod 12 and the pallet 18 in the middle of that is to say.The left end of pallet 18 is shaped on outside thread, big diaphragm 16 thereby be to be set as on radial face central hole and that be close to pallet, and this moment is fixing by means of compress gasket 14 and locknut 16.Each section and internal and external threads guarantee that by technology its concentricity helps the stability of member work on the pallet 18.The vent D that service brake chamber A sets up as signal port helps forming full automaticity emergency braking system with corresponding construction.
The principle of work of the utility model membrana perforata chip type spring energy storage brake repair room is identical with existing two diaphragm type spring energy storage brake repair rooms, for example when service brake chamber A and spring energy-storage brake repair room B interruption air feed, just elongation of energy stroage spring 19, promote pallet 18, middle push rod 12 and middle push-plate 5, then promote Small diaphragm-piece 9, push-plate 8 and push rod 2, thus implement emergency braking.When pressurized air per os E enters spring energy-storage brake repair room B, atmospheric pressure is through big diaphragm 16, pallet 18 compressed energy-storage springs 19, when air pressure rises to certain value, atmospheric pressure moves until withstanding on the bonnet 20 after just making pallet 18, middle push rod 12 that be attached thereto this moment and middle push-plate 5 intact total retrusions, push-plate 8 resets under pull back spring 6 effects, thereby removes emergency braking.When pressurized air per os C entered service brake chamber A, atmospheric pressure made push rod 2 reaches implement service brake; When pressurized air is discharged service brake chamber A, push rod 2 brake off that resets.When need were removed the emergency braking of spring energy-storage brake repair room B, removable being stated from down freed bolt 11 on the intermediate 15, opened dustproof stifled 22 on the bonnet 20, and the negative thread by middle push rod 12 retracts its pressure frees.
Practice shows, the utility model punch diaphragm spring energy-storing brake chamber and existing skill The art structure is compared its outstanding advantages and is embodied in that sealing is tight, guiding is good and working stability Reliably, that is to say, its job stability and reliability are increased significantly.
