Abstract
The utility model discloses a backflow type vent cap for a deceleration or speed changing box used for a vehicle, which relates to a venting leakage-proof device for a lubricating oil cavity of the deceleration (or speed changing) box of the vehicle. An opening is arranged on the upper surface of the vent cap body; a cap cover is buckled at the opening on the upper surface of the vent cap body and is provided with a venting hole; a vertical tubular body is arranged at the center of the vent cap body; a filter body is arranged in the vent cap body and is sheathed outside the tubular body; the upper end surface of the tubular body is lower than the upper surface of the filter body; a first connector extending out a position below the vent cap body is arranged at the center of the bottom of the vent cap body; an oil spilling hole is communicated between the lower end surface of the first connector and the upper end surface of the tubular body at the center in the vent cap body; a second connector is connected with the edge of the bottom of the vent cap body, extends out below the bottom of the vent cap body and is bent by 90 degrees towards the outer side; and a return opening is arranged in the second connector and is communicated to the interior of the vent cap body. The backflow type vent cap can ensure ventilation and leakage prevention, and can prevent dust from entering a box body.
Description
Technical field
The utility model relates to the fast case lubricant reservoir ventilation of a kind of automobile-used subtracting (change) leakage protection device.
Background technique
The lubricating condition of transmission component requires very fully in the fast case of automobile-used subtracting (change), has slightly improperly will damage the power transmission part, even scraps.Automobile-used in addition (change) the fast case that subtracts is normal in service along with the rising of operating temperature and the raising of movement parts rotating speed; Pressure in the case can constantly rise; Produce the foamed gas mixture of part simultaneously, each Sealing will lose seal action and cause leakage of oil during case internal pressure (above 0.03Mpa) in a single day out of hand.The abat-vent of the fast case of automobile-used subtracting (change) generally adopts following two kinds of modes at present: the one, and the pressure limiting abat-vent; Abat-vent is sealing shape (stuffiness) when in subtracting (change) fast case, being lower than authouized pressure; Abat-vent exhaust when the case internal pressure surpasses authouized pressure; Have part oil gas temperature compound in the time of exhaust and discharge befouling environment; Subtract each Sealing work under certain pressure state all the time in (change) fast case simultaneously, will lose efficacy in advance, influence its working life.The 2nd, unlimited straightening general formula abat-vent; Subtract in (change) fast case and directly follow atmosphere through the overflow hole on the abat-vent, pressing in exhaust does not receive does not influence, and not enough is that outside dust can directly get into; Lubricant oil can be lost efficacy in advance; Inner gas mixture or lubricant oil also can directly overflow, and lose seal action, and befouling environment.Above-mentioned two kinds of abat-vents all have deficiency, moreover its interior pressure limiting element pressure limiting required precision of limited pressure abat-vent is very high, and domestic manufacturer all is difficult to reach the requirement that its pressure opens and closes scope at present, and each automotive transmission producer all depends on import.
The model utility content
Be the problem that the existing technology that solves exists, the utility model provides a kind of automobile-used deceleration or gearbox to use the return flow type abat-vent, and it can guarantee both to ventilate, leakproof; Dust protection gets within the casing again.
For addressing the above problem, the utility model adopts following technological scheme: be made up of cap 1, filter 2 and abat-vent body 3; Above the said abat-vent body 3 opening is arranged, the opening of cap 1 spiral-lock on abat-vent body 3 has vent 1-1 on the cap 1; Centre bit is equipped with a vertical tube body that is provided with in the abat-vent body 3, and filter 2 is positioned at abat-vent body 3 and is set in the tube body outside, and the upper-end surface of tube body is lower than the height above the filter 2; The first interface 3-1 that stretch out oriented abat-vent body 3 belows, abat-vent body 3 bottom centre positions, oil spilling hole 3-2 are communicated between the tube body upper-end surface of lower end surface and abat-vent body 3 inside center of the first interface 3-1; Abat-vent body 3 bottom sides are along being connected with one second interface 3-3, and the second interface 3-3 stretches out and is 90 degree laterally to below, abat-vent body 3 bottoms and bends; The return opening 3-4 that is communicated to abat-vent body 3 inside is arranged in the second interface 3-3.
The utility model can be guaranteed ventilation, has drip-preventing function simultaneously, can also prevent that dust from getting within the casing.
Description of drawings
Fig. 1 is the utility model structural representation.
Symbol description among the figure: cap 1, vent 1-1, filter 2, abat-vent body 3, the first interface 3-1, oil spilling hole 3-2, the second interface 3-3, return opening 3-4.
Embodiment
As shown in Figure 1, automobile-used deceleration or gearbox are used the return flow type abat-vent, are made up of cap 1, filter 2 and abat-vent body 3; Above the said abat-vent body 3 opening is arranged, the opening of cap 1 spiral-lock on abat-vent body 3 has vent 1-1 on the cap 1; Centre bit is equipped with a vertical tube body that is provided with in the abat-vent body 3, and filter 2 is positioned at abat-vent body 3 and is set in the tube body outside, and the upper-end surface of tube body is lower than the height above the filter 2; The first interface 3-1 that stretch out oriented abat-vent body 3 belows, abat-vent body 3 bottom centre positions, oil spilling hole 3-2 are communicated between the tube body upper-end surface of lower end surface and abat-vent body 3 inside center of the first interface 3-1; Abat-vent body 3 bottom sides are along being connected with one second interface 3-3, and the second interface 3-3 stretches out and is 90 degree laterally to below, abat-vent body 3 bottoms and bends; The return opening 3-4 that is communicated to abat-vent body 3 inside is arranged in the second interface 3-3.
Above-mentioned filter part 2 employings have filtration, vent ability material good, oil resistant is processed.
Its installation method is: first interface of abat-vent body spare 3 links to each other with the oil filler that subtracts (change) fast case, and other mouths that second interface adopts the pipe oil level viewing window fast with subtracting (changes) or is lower than oil filler link to each other.
Working principle is: after installing by above-mentioned installation method, when subtracting (changes) fast case and normally moving, the gas mixture in its case prolongs overflow hole and rises, and after filter part 2 filtered, gas prolonged vent and overflows, and the lubricant oil sinking is also prolonged refluxing opening and got back in the casing.Extraneous dust (foreign material) also can be blocked by filter even wait from the ventilating hole entering, can directly not get into to subtract in (change) fast casing.Need the periodic replacement filter in the use, to guarantee the function of its filtration and ventilation.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to mode of execution.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all mode of executions.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
