Description
Technical field
The present invention relates to auto-parts technical field.
Background technology
On vehicle rear axle assembly, ventilation valve assembly plays balance rear axle assy external and internal pressure as air-breather, prevents
The effect that outside muddy water, dust are entered inside rear axle assy.Existing vent valve structure is more by ventilation valve body, ventilation bonnet, rubber
Glue gasket and spring are constituted, and breather valve cap sleeve is located on ventilation valve body and with ventilation valve body and is connected using riveting, and rubber sheet gasket leads to
Spring compression is crossed on ventilation valve body, when rear axle assy operating temperature reaches 90 ° or so, gear oil forms oil vapour and then produces
Air pressure, when rear axle assy air pressure inside is more than spring pressure, rubber sheet gasket is upwardly opened by jack-up, and oil vapour is from breather valve
Realization exhaust is released in space between cap and ventilation valve body, breather valve is not opened when rear axle assy air pressure inside is less than spring pressure
Open.Because automobile generally individually has fording depth requirement, and fording depth is more deep better, and existing breather valve is adopted by bullet
Spring force controls the version of Opening pressure, and on the premise of Opening pressure is met, back axle is total when car load is travelled in deep water
Into often occurring into water phenomenon, gear luboil cleanness thus will be caused overproof, so as to cause rear axle assy inner oil seal oil leak, axle
Hold, oil sealing, gear premature breakdown, and a series of problems, such as back axle abnormal sound；And increase spring force, it is adjusted to satisfaction and relates to
Water depth is unsatisfactory for the requirement of Opening pressure again when requiring, it is excessive to easily cause rear axle assy air pressure inside, oil sealing internally pressure
Open outside the lower lip of effect, and then Leakage occurs, therefore existing vent valve structure constrains the fordability of automobile.
The content of the invention
To solve the problems, such as above-mentioned prior art, the invention is intended to a kind of automobile waterproof vent valve is provided, to meet
Exhaust demand of the vehicle rear axle assembly under normally travel state, and in automobile wading can self-closed ventilation space, can
Prevent water from entering in breather valve, to meet the needs of paddling of automobile.
Automobile waterproof vent valve in this programme, including the valve body on rear axle assy, also including valve bonnet and two
Individual or plural buoyancy body, the upper end of the valve body is connected with the end cap of annular, and the valve bonnet is connected to outside valve body, institute
State and be tightly connected outside the poor lower end of valve and valve body, gap is left between valve bonnet and valve body, the valve bonnet is vertically provided with
Some equally distributed bar holes, the buoyancy body is provided with slide block and slide block coordinates in the bar hole, and slide block is worn
Cross valve bonnet to enter in the gap between valve bonnet and valve body, the buoyancy body is cavity structure；The outside of the valve body is provided with cunning
Set, the slide block mode connects for screw on sliding sleeve and all buoyancy bodies, the common mode connects for screw in upper end of all slide blocks has consolidating for annular
Determine block, the upper end of the fixed block is bonded with O-ring seal.
Operation principle：Oil vapour is discharged by valve body upper end, then in the gap between valve bonnet and valve body, is passed through
The bar hole that valve bonnet is provided with is discharged.When automobile wading, the breather valve is entered in water, sliding because buoyancy body is cavity structure
Block slides in bar hole, therefore buoyancy body is raised under buoyancy of water effect, and the slide block in all buoyancy bodies is by annular
Fixed block is fixed, and makes all buoyancy body synchronization upward slidings, O-ring seal that the contacts-side-down moved with end cap is driven by slide block,
With confining gas flow channel, prevent water from entering bar hole in valve body, realize waterproof.
Beneficial effect：Using above-mentioned technical proposal, exhaust need of the vehicle rear axle assembly under normally travel state can be met
Ask, and in automobile wading can self-closed ventilation space, can prevent water enter valve body in, to meet the need of paddling of automobile
Will, and its simple structure, leaking for rear axle assy internal gear oil can be reduced, with good practicality.
Further, the upper end of the valve bonnet is provided with opening, and valve bonnet upper end is removably connected with valve gap, can dismantle valve gap pair
Parts in valve bonnet are mounted and dismounted, convenient handling.
Further, the threaded upper ends connection of the valve gap and valve bonnet, is provided with pad, spiral shell between valve gap and valve bonnet upper port
Line attachment structure is simple, loads convenient, and positioned spacers can increase the sealing between valve gap and valve bonnet.
Further, the quantity of the buoyancy body is four, increases buoyancy, improves the stability of waterproof.
Further, the sliding sleeve includes body, and located at the installing plate at body two ends, the external diameter of the installing plate is less than
The external diameter of body, installing plate is provided with the screwed hole for mounting screw.Installing plate is set, is easy to the connection of sliding sleeve and slide block.
Further, the connected mode outside the lower end of the valve bonnet and valve body is welding, and the connected mode of welding is more firm
Gu, it is stable, and good airproof performance, prevent current from entering in valve bonnet from connecting portion.
