Abstract
The utility model discloses a two diaphragm brake chamber, include and close the parking chamber of enclosing by well body back cap seal, the parking intracavity is equipped with tappet, tappet dish, involucra and release dish, between the body and back were covered during involucra, release dish were located, wherein, be equipped with tappet return spring between the tappet dish and the well body, be equipped with powerful spring between release dish and back lid, be equipped with first location pit and boss on the involucra, be equipped with on the release dish with boss assorted second location pit. The utility model provides a two diaphragm brake chamber through set up first location pit and boss on the involucra, sets up second location pit on the release dish, through tappet dish and the cooperation of involucra pit, and release dish pit and the cooperation of involucra boss, the good location of realizing release dish and the relative involucra of tappet to effectively avoiding release dish radial deflection, slowing down wearing and tearing, the product operational reliability is improved to the extension arrester life -span.
Description
Technical field
The utility model relates to a kind of brake chamber, particularly relates to a kind of two diaphragm brake actuator.
Background technique
In traditional double diaphragm arrester parking chamber, release dish, epithelium, tappet touching position are plane contact, tappet also just singly supports location, during brake chamber jolts with car, release dish may depart from central position, causes brute spring to be applied to active force skew on tappet, makes the stressed irregular and early failue of epithelium, tappet slip resistance in middle body opening increases, and middle body mesopore wearing and tearing aggravate and lost efficacy.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of two diaphragm brake actuator, the good location of release dish epithelium relative to tappet can be realized, effectively avoid release dish radial deflection, slow down wearing and tearing, extend the arrester life-span and improve product work reliability.
The utility model is solve the problems of the technologies described above the technological scheme adopted to be to provide a kind of two diaphragm brake actuator, comprise and close by middle body bonnet the parking chamber surrounded, tappet, tappet dish, epithelium and release dish is provided with in described parking chamber, described epithelium, release dish are located between middle body and bonnet, wherein, tappet return spring is provided with between described tappet and middle body, brute spring is provided with between described release dish and bonnet, described epithelium is provided with the first location dimples and boss, and described release dish is provided with the second location dimples matched with described boss.
Above-mentioned two diaphragm brake actuators, wherein, the inwall of described epithelium stretches out after turnover and forms chimb, described chimb is provided with wedge bearing seal.
The utility model contrast prior art has following beneficial effect: two diaphragm brake actuators that the utility model provides, by arranging the first location dimples and boss on epithelium, release dish arranges the second location dimples, coordinate the spring of tappet front end and back end, realize the good location of release dish epithelium relative to tappet, thus effectively avoid release dish radial deflection, slow down wearing and tearing, extend the arrester life-span and improve product work reliability.

Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the two diaphragm brake actuator structural representation of the utility model.
Refer to Fig. 1, two diaphragm brake actuators that the utility model provides, comprise and close by middle body bonnet the parking chamber surrounded, tappet 2, middle body 3, epithelium 4 and release dish 5 is provided with in described parking chamber, described epithelium 4, release dish 5 are located between middle body 3 and bonnet 7, wherein, tappet return spring 1 is provided with between described tappet dish 10 and middle body 3, brute spring 6 is provided with between described release dish 5 and bonnet 7, described epithelium 4 is provided with the first location dimples and boss, and described release dish is provided with the second location dimples matched with described boss.
Two diaphragm brake actuators that the utility model provides, by arranging the first location dimples and boss on epithelium 4, release dish 5 arranges the second location dimples, coordinates the spring of epithelium 4 front end and back end, tappet dish 10, epithelium 4, release dish 5 are matched, tappet 4 single supporting operating mode is made to be improved as dual-supporting operating mode, when tappet 2 slides in middle body 3 hole, cross component force reduces, and frictional force reduces, and activity is more flexible, mesopore wearing and tearing slow down, and the arrester life-span is extended.Two diaphragm brake actuators that the utility model provides, the inwall of described epithelium 4 preferably stretches out and turns down rear formation chimb 8, and described chimb 8 is provided with wedge bearing seal; Supported by wedge, make product in use increase area of contact, reach product in use more steady.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
Claims (2)
1. a two diaphragm brake actuator, comprise and close by middle body bonnet the parking chamber surrounded, tappet, tappet dish, epithelium and release dish is provided with in described parking chamber, described epithelium, release dish are located between middle body and bonnet, it is characterized in that, between described tappet dish and middle body, be provided with tappet return spring, between described release dish and bonnet, be provided with brute spring, described epithelium is provided with the first location dimples and boss, and described release dish is provided with the second location dimples matched with described boss.
2. diaphragm brake actuator as claimed in claim 1 two, is characterized in that, the inwall of described epithelium stretches out after turnover and forms chimb, described chimb is provided with wedge bearing seal.
