Abstract
The utility model provides a waterproof automobile gearbox ventilation plug, which mainly solves the problems that parts in a control mechanism are corroded and lubricating oil is polluted because the existing automobile gearbox ventilation plug cannot effectively prevent external dust particles and water vapor from entering the gearbox, and cannot effectively prevent oil gas in the gearbox from flowing outwards. The automobile gearbox ventilation plug comprises a ventilation plug cap and a ventilation plug cover which are matched with a ventilation plug rod, wherein the ventilation plug cap and the ventilation plug cover are arranged on the ventilation plug rod; a cavity is formed in the ventilation plug rod by the ventilation plug cap and the ventilation plug cover; vent holes are formed on the ventilation plug cover; space cotton is filled in the cavity; ventilation holes are formed in the ventilation plug rod; and the ventilation holes are communicated with the cavity.
Description
Technical field
The utility model provides a kind of automobile gearbox breather plug, is specifically related to a kind of automobile gearbox breather plug of anti-water inlet, and this breather plug also can be used for association areas such as transfer case, power take-off.
Background technique
The breather plug major function is exhaust, and existing automobile gearbox possibly can't effectively stop extraneous dust granule and steam to get into gearbox inside when working in comparatively harsh working environment with breather plug; The inner oil gas of gearbox also may flow out from breather plug; Befouling environment, particularly the rainwater sprinkle is on breather plug for a long time, and rainwater can infiltrate breather plug; Cause the corrosion of operating mechanism inner body, lubricant pollution.
Summary of the invention
The utility model provides a kind of automobile gearbox breather plug of anti-water inlet, has mainly solved existing automobile gearbox breather plug and can't effectively stop extraneous dust granule and steam to get into gearbox inside, thereby caused the corrosion of operating mechanism inner body, lubricant pollution; The problem that also can't effectively stop the inner oil gas of gearbox outwards to flow out simultaneously.
The concrete technical solution of the utility model is following:
Should prevent the automobile gearbox breather plug of water inlet; Comprise the ventilation cock cap and ventilation gag suitable with the ventilation stopper rod, the ventilation cock cap is arranged on the ventilation stopper rod with the ventilation gag, and the ventilation cock cap constitutes cavity with the ventilation gag on the ventilation stopper rod; Breather plug covers and is provided with exhaust port; Be filled with space wadding in the cavity, be provided with vent in the ventilation stopper rod, vent is communicated with cavity.
Above-mentioned ventilation gag is the horn mouth shape, and said exhaust port is at least one the u type groove that is provided with on the bell-mouthed edge; Said ventilation gag is the cylindrical cap of a side opening.
The above-mentioned ventilation stopper rod one end outside is six side's bench-types, and the other end arranged outside is useful on the outside thread of connection; Vent on the said ventilation stopper rod comprises axial bore and upright opening perpendicular to axial direction, and axial bore and upright opening are communicated with.
It specifically is that the ventilation cock cap press-fits with the ventilation gag or is welded on the ventilation stopper rod on the stopper rod that above-mentioned ventilation cock cap and ventilation gag are arranged on ventilation.
The advantage of the utility model is following:
Not only exhaust is unimpeded for the automobile gearbox breather plug that the utility model provides, and stops the inner oil gas of gearbox outwards to flow out, and can also prevent the extraneous dust and the entering of rainwater simultaneously, avoids component corrosion and the pollution of lubricant oil in the gearbox operating mechanism.This automobile gearbox breather plug is joined and convenient disassembly, and is simple in structure, good manufacturability, excellent performance.
Simultaneously, exhaust unobstructed with stop introduced contaminants get into oil gas flow out conflicting, especially in pneumatic element, and the anti-water inlet automobile gearbox breather plug that the utility model provides both have it concurrently; During high temperature, oil gas tends to flow out from the gearbox breather plug.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is detailed, as shown in Figure 1:
Automobile gearbox breather plug that should anti-water inlet comprises the ventilation cock cap 2 and ventilation gag 1 suitable with ventilation stopper rod 4, and ventilation cock cap 2 press-fits with ventilation gag 1 or is welded on the ventilation stopper rod 4.Ventilation gag 1 is the horn mouth shape, on bell-mouthed edge, has the groove of ventilation.Ventilation gag 2 is cylindrical, a side opening.Ventilation stopper rod 4 outer ends are for ease of the Liu Fangtai of assembling and dismounting, and there are the outside thread of connection and the endoporus of ventilation in the inner, on the ventilation stopper rod 4 vent perpendicular to axial direction arranged.Ventilation cock cap 2 outsides are near the Liu Fangtai on the ventilation stopper rod 4, and opening is to the ventilation end, and the horn mouth of ventilation gag 1 is close to ventilation cock cap 2 bottoms, and ventilation gag 1 interlocks with ventilation cock cap 2.Between ventilation gag 1 and the ventilation stopper rod 4 an amount of space wadding is arranged.
After the gearbox temperature raise, inner oil gas, air pressure got into from ventilation stopper rod 4 internal ports, get into space wadding through the vent on the ventilation stopper rod 4, and air pressure filters the back from space wadding and flows out, and the U-shaped vent slot from ventilation gag 1 horn mouth is discharged.Oil gas is attracted on the space wadding, can not flow to atmosphere easily.The extraneous dust of breather plug can be attracted on the space wadding when getting into breather plug, can't get into breather plug inside.Because ventilation gag 1 has certain length with ventilation cock cap 2, ventilation gag 1 be the horn mouth shape, and ventilation cock cap 2 is buckled together with ventilation gag 1 each other, and the rainwater cock cap 2 of being ventilated keeps off outside space wadding with ventilation gag 1, makes rainwater can't get into breather plug.This breather plug assembling and convenient disassembly, simple in structure, good manufacturability, excellent performance.
