Abstract
The utility model relates to a breather assembly of a 6AT automatic transmission, and the breather assembly comprises a breather body (1) and a protective helmet (2); one end of the breather body (1) is sleeved with the protective helmet (2), and the middle part of the breather body (1) is provided with a circular limit block (3); the end surface of the sleeved end of the breather body (1) with the protective helmet (2) is provided with a step (4); compared with the prior art, according to the breather assembly of the 6AT automatic transmission, because the end surface of the sleeved end of the breather body with the protective helmet is provided with the step, after the step is arranged, the bottom surface of the protective helmet can only be jointed with a step surface in breath-in; a gap is left between the bottom surface of the protective helmet and the end surface of the other part of the breather body, so that gas can normally penetrate through the gap and enters a breathing hole of the breather body, the stable work of the 6AT automatic transmission is effectively ensured, and the 6AT automatic transmission is not damaged and even scrapped.
Description
Technical field
The utility model belongs to and relates to a kind of 6AT automatic transmission case air breather assembly.
Background technique
At present, the 6AT automatic transmission case air breather assembly of prior art (being also referred to as 6AT automatic transmission case vent valve assembly) comprises resuscitation apparatus body 1 ' and protective hat 2 ' as shown in Figure 1, resuscitation apparatus body 1 ' one end is connected with protective hat 2 ', and be provided with circumferential projection 3 ' near the end of resuscitation apparatus body 1 ' and protective hat 2 ' connecting end, and part is inwardly turned up at the edge of protective hat 2 ' opening so that protective hat 2 ' can be spacing by projection 3 ' when movable, thereby so that protective hat 2 ' can not thrown off with resuscitation apparatus body 1 ', and certain activity space arranged, but because the end face of resuscitation apparatus body 1 ' and protective hat 2 ' connecting end is the plane, when air-breathing, very easily fit with the end face of resuscitation apparatus body 1 ' in protective hat 2 ' bottom surface, and cause the resuscitation apparatus body 1 ' can't be air-breathing, and then cause gearbox to occur damaging or even the situation of scrapping.So there is the relatively poor problem of stability in use in the 6AT automatic transmission case air breather assembly of prior art.
The model utility content
The utility model provides preferably 6AT automatic transmission case air breather assembly of a kind of stability in use for above problem.
The utility model overcomes the above problems used technological scheme: a kind of 6AT automatic transmission case air breather assembly with following structure is provided, it comprises resuscitation apparatus body and protective hat, one end of described resuscitation apparatus body and protective hat socket, the middle part of described resuscitation apparatus body is provided with the limiting stopper of annular, and the end face of described resuscitation apparatus body and protective hat socket end is provided with step.
After adopting above structure, compared with prior art, the utility model is because the end face of resuscitation apparatus body and protective hat socket end is provided with step, after then step arranges, when air-breathing, can only fit with step surface in the bottom surface of protective hat, and leave the gap between protective hat bottom surface and the other part resuscitation apparatus body end face, so can guarantee gas can enter in the spiracle of resuscitation apparatus body by this gap normally, thereby the stable work of assurance 6AT automatic transmission case effectively prevents that the 6AT automatic transmission case from occur damaging or even the situation of scrapping.Therefore stability in use of the present utility model is better.
As improvement, the bottom surface of described protective hat is provided with at least one projection, described projection is positioned on the position of protective hat bottom surface proximal edges, then after the bottom surface of protective hat arranges projection, when air-breathing, protective hat moves to the resuscitation apparatus body, projection contacts with resuscitation apparatus body end face or step surface first, protective hat Fang Sheng tilts under the effect of projection subsequently, and then so that the gap between protective hat and the resuscitation apparatus body end face is larger, thereby further guarantee the efficient of 6AT automatic transmission case tidal air, so so that stability in use of the present utility model further improve.
As further improvement, distance between described projection and the protective hat opening edge is greater than the distance between ledge surface and the nearly protective hat end of the limiting stopper end face, then when projection is fitted with resuscitation apparatus body end face or step surface, can not fit with the end face of limiting stopper in the edge of protective hat opening yet, so that extraneous gas can enter in the protective hat effectively, thereby enter in the 6AT automatic transmission case by the resuscitation apparatus body, guarantee the operational efficiency of 6AT automatic transmission case and the stability of operation, when the end face that prevents the edge of original protective hat opening and limiting stopper is fitted, ambient atmos occurs and can't enter the interior situation of protective hat, so so that stability in use of the present utility model is higher.
As preferably, described projection is three, and along circumferentially evenly distributing.
Description of drawings
Fig. 1 is the structural representation of prior art 6AT automatic transmission case air breather assembly.
Fig. 2 is the structural representation of the utility model 6AT automatic transmission case air breather assembly.
As shown in the figure: 1 ', resuscitation apparatus body, 2 ', protective hat, 3 ', projection.
1, resuscitation apparatus body, 2, protective hat, 3, limiting stopper, 4, step, 5, projection.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
A kind of 6AT automatic transmission case air breather assembly as shown in Figure 2, it comprises resuscitation apparatus body 1 and protective hat 2, one end of described resuscitation apparatus body 1 and protective hat 2 sockets, the middle part of described resuscitation apparatus body 1 is provided with the limiting stopper 3 of annular, described resuscitation apparatus body 1 is provided with step 4 with the end face of protective hat 2 socket ends, certainly the edge of protective hat 2 openings is inwardly turned up, and remaining structure all structure with prior art is identical.
It is three that the bottom surface of described protective hat 2 is provided with at least one protruding this example of 5(, can also be one, two or four etc.), described protruding 5 are positioned on the position of protective hat 2 bottom surface proximal edges.General protective hat 2 makes for the metallic material impact briquetting, projection 5 also direct on protective hat 2 impact briquetting make.
Described protruding 5 and protective hat 2 opening edges between distance greater than the distance between step 4 surface and the limiting stopper 3 nearly protective hat 2 end end faces.
Described protruding 5 is three, and along circumferentially evenly distributing.
Above embodiment only is preferred embodiment of the present utility model, and the utility model is not limited only to above embodiment and has also allowed other structural change, allly changes in the utility model rights to independence claimed range, all belongs to the utility model protection domain.
