Description
Technical field
The present invention relates to auto-parts technical fields.
Background technique
On vehicle rear axle assembly, ventilation valve assembly plays balance rear axle assy external and internal pressure, prevents as air-breather
External muddy water, dust enter the effect inside rear axle assy.Existing vent valve structure is mostly by ventilation valve body, ventilation bonnet, rubber
Glue gasket and spring composition, breather valve cap sleeve are located on ventilation valve body and are connected with ventilation valve body using riveting, and rubber sheet gasket is logical
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 generates
Air pressure, when rear axle assy air pressure inside is greater than spring pressure, rubber sheet gasket is jacked up and is upwardly opened, and oil vapour is from breather valve
Realization exhaust is released in gap between cap and ventilation valve body, breather valve is not opened when rear axle assy air pressure inside is less than spring pressure
It opens.Since automobile generally has fording depth requirement, and the deeper fording depth the better, and passes through bullet used by existing breather valve
Spring force controls the structure type of cracking pressure, and under the premise of meeting cracking pressure, rear axle is total when driving in deep water for vehicle
At often will appear into water phenomenon, thus gear luboil cleanness will be caused overproof, to cause rear axle assy inner oil seal oil leak, axis
It holds, oil sealing, gear premature breakdown and a series of problems, such as rear axle abnormal sound；And increase spring force, it is adjusted to satisfaction and relates to
Water depth is unsatisfactory for the requirement of cracking pressure again when requiring, easily cause rear axle assy air pressure inside excessive, oil sealing is in internal pressure
It acts on and being opened outside lower lip, and then Leakage occurs, therefore existing vent valve structure constrains the fordability of automobile.
Summary of the invention
To solve the above-mentioned problems of the prior art, the invention is intended to provide a kind of automobile waterproof vent valve, to meet
Exhaust demand of the vehicle rear axle assembly under normally travel state, and in automobile wading can self-closed ventilate gap, can
Prevent water from entering in breather valve, to meet the needs of paddling of automobile.
Automobile waterproof vent valve in this programme further includes valve bonnet and two including the valve body being mounted on rear axle assy
A or more than two buoyancy bodies, the upper end of the valve body are connected with the end cap of annular, and the valve bonnet is connected to outside valve body, institute
It states and is tightly connected outside the lower end and valve body of valve bonnet, there are gap between valve bonnet and valve body, the valve bonnet is equipped with along the vertical direction
Several equally distributed strip-shaped holes, the buoyancy body is equipped with sliding block and sliding block cooperation in the strip-shaped hole, and sliding block is worn
It crosses 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 equipped with cunning
Set, sliding sleeve connects with the sliding block screw in all buoyancy bodies, and the common screw in the upper end of all sliding blocks is connected with one and annular consolidates
Determine block, the upper end of the fixed block is bonded with ring type seal.
Working principle: oil vapour is discharged by valve body upper end, then into the gap between valve bonnet and valve body, is passed through
The strip-shaped hole discharge that valve bonnet is equipped with.When automobile wading, which enters in water, sliding since buoyancy body is cavity structure
Block slides in strip-shaped hole, therefore buoyancy body is raised under the buoyancy of water, and the sliding block in all buoyancy bodies passes through annular
Fixed block is fixed, and the synchronous upward sliding of all buoyancy bodies is made, and ring type seal is driven the contacts-side-down moved up with end cap by sliding block,
It with confining gas flow channel, prevents water from entering in valve body into strip-shaped hole is crossed, realizes waterproof.
The utility model has the advantages that by adopting the above technical scheme, exhaust need of the vehicle rear axle assembly under normally travel state can be met
Ask, and in automobile wading can self-closed ventilate gap, can prevent water from entering in valve body, to meet the need of paddling of automobile
It wants, and its structure is simple, leaking for rear axle assy internal gear oil can be reduced, there is good practicability.
Further, the upper end of the valve bonnet is equipped with opening, and valve bonnet upper end is removably connected with valve deck, can dismantle valve deck pair
Components in valve bonnet are mounted and dismounted, convenient for loading and unloading.
Further, the valve deck is connected with the threaded upper ends of valve bonnet, and gasket, spiral shell are equipped between valve deck and valve bonnet upper port
Line connection structure is simple, and it is convenient to load, and positioned spacers can increase the leakproofness between valve deck and valve bonnet.
Further, the quantity of the buoyancy body is four, increases buoyancy, improves the stability of waterproof.
Further, the sliding sleeve includes ontology, and the mounting plate set on ontology both ends, and the outer diameter of the mounting plate is less than
The outer diameter of ontology, mounting plate are equipped with the threaded hole for mounting screw.Mounting plate is set, convenient for the connection of sliding sleeve and sliding block.
Further, the lower end of the valve bonnet and the connection type outside valve body are welding, and the connection type of welding is more firm
Gu stablizing, and good airproof performance, prevent water flow from entering in valve bonnet from connecting portion.
