Abstract
A kind of gearbox vent plug, it is characterised in that：The abat-vent of casing and rubber production including bending design, abat-vent is inserted in casing, cooperated between the two interface using the back-off of interference, abat-vent is the structure of elongated cylindrical, it is rubber boot at the top of abat-vent, middle part is annular convex platform, upper position uses the design of inverted V type blow vent in its inner cavity, casing is the hollow structure of the Y type of bending, sleeve bottom interface is designed using wave card slot, cooperate with gearbox stomata interface position, there is oval anti-rotation boss on the ring-shaped platform of middle part, its vertical direction and casing main body are that the abat-vent with back-off is taken at 30 ° of bendings.The utility model realizes ventilation, the balance external world and speed change box cavity temperature and pressure, solves the problems, such as the insufficient lubrication and power problem of transmission caused of current gearbox vent plug waterproof ability.
Description
Technical field
The utility model relates to a kind of automobile gearbox ventilation plug structures.
Background technique
There are two the effects of breather plug, and one is to maintain the balance of gearbox Yu ambient pressure and temperature；Second is that stopping extraneous
Dust and water enter speed change box cavity.The length of general breather plug, the design of the abat-vent the brim of a hat is very short, to the spray of splashing
Occlusion effect is limited；Casing is the metal structure of hollow cylinder, can generate apparent gap with abat-vent assembly, can not stop water
Stream；Therefore the waterproof ability of General vent plug black box is insufficient.When vehicle passes through the puddles of water or has the road conditions of certain depth of accumulated water
When, the spray that wheel is rolled or splashed, breather plug also results in spray in the position of vehicle and flows into along abat-vent internal surface of sleeve pipe
Speed change box cavity.The spray that casing wall or shell reflective splash flows into inside pipe casing by the gap of abat-vent and casing, and by
The effect of gravitional force drops onto gearbox oil liquid, makes the performance of gear box oil by serious influence, not only greasy property
Impaired, transmitting power performance can also decline, so that the bearing of transmission internal is reduced, the service life of the parts such as gear.
Summary of the invention
The purpose of this utility model is to provide a kind of gearbox vent plugs, overcome General vent plug waterproof ability insufficient easily
Lead to the disadvantage that gear box oil lubricates and transmitting power performance is impaired.
A kind of gearbox vent plug, it is characterised in that：The abat-vent of casing and rubber production including bending design, ventilation
Cap sleeve enters casing, is cooperated between the two interface using the back-off of interference, abat-vent is the structure of elongated cylindrical, and casing is bending
The hollow structure of Y type improves the water proof and dust proof ability of breather plug.
A kind of gearbox vent plug, it is characterised in that：It is rubber boot at the top of abat-vent, middle part is annular convex platform,
Upper position uses the design of inverted V type blow vent in inner cavity.
A kind of gearbox vent plug, it is characterised in that：Sleeve bottom interface is designed using wave card slot, is ventilated with gearbox
The cooperation of hole interface position, has oval anti-rotation boss, vertical direction and casing main body at 30 ° of bendings on the ring-shaped platform of middle part
It is the abat-vent adapter tube with back-off.
The utility model has the advantages that：The utility model realizes ventilation, the balance external world and speed change box cavity temperature and pressure
Power solves the problems, such as the insufficient lubrication and power problem of transmission caused of current gearbox vent plug waterproof ability.Pass through casing
The cooperation of the groove of oval anti-rotation boss and shell, determining setting angle and positioning with shell guarantee ventilation plug assembly whole
Safety clearance in vehicle arrangement.Since rubber is excessively soft, the back-off design of abat-vent adapter tube prevents abat-vent from loosening.The rubber of abat-vent
Glue protective cover and annular convex platform play a part of to stop water and dust, and inverted V type blow vent ensures ventilatory function.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is abat-vent structural schematic diagram in Fig. 1；
Fig. 3 is Fig. 1 middle sleeve structural schematic diagram；
In figure：Abat-vent 1, rubber boot 11, annular convex platform 12, inverted V type blow vent 13, casing 2, wave card slot 21,
Abat-vent adapter tube 22, anti-rotation boss 23.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
A kind of gearbox vent plug, it is characterised in that：The abat-vent 1 of casing 2 and rubber production including bending design, leads to
Gas cap 1 is inserted in casing 2, is cooperated between the two interface using the back-off of interference, abat-vent 1 is the structure of elongated cylindrical, abat-vent 1
Top is rubber boot 11, and middle part is the annular convex platform 12 that outer diameter is 27 ± 0.5 mm of φ, and upper position uses in inner cavity
The design of inverted V type blow vent 13；Casing 2 is the hollow structure of the Y type of bending, and 2 bottom interface of casing is set using wave card slot 21
Meter cooperates with gearbox stomata interface position, has the oval anti-rotation that height is 2 ± 0.1 mm convex on the ring-shaped platform of middle part
The oval anti-rotation boss 23 of platform 23, gear box casing groove and casing cooperates, and is pressed into housing vent hole peace with sleeve tooling
Dress face；Its vertical direction and casing main body are the abat-vent adapter tube 22 with back-off, abat-vent 1 and abat-vent adapter tube at 30 ° of bendings
22 back-off elastic conjunctions, are pressed into the mounting surface of abat-vent adapter tube 22.
Utility model works principle：When gearbox operation, gear drives atomization and the inner chamber gas of gear box oil
Expansion makes intracavitary pressure in it rise sharply, and as revolving speed improves, oil temperature is also with improve.The utility model breather plug is by falling V
Type blow vent 13 balances external and internal pressure and temperature.When encountering the puddles of water or ponding road conditions, rubber boot 11 and annular convex platform 12
Multiple obstruction is formed to the spray of splashing, i.e. rubber boot 11 itself can block water, and the soft interference with annular convex platform 12 is matched
Conjunction forms exocoel and can continue that minority is stopped to infilter the water come, can not just squeeze into without enough pressure water, has well
Waterproof ability.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, make several equivalent substitute or obvious modifications without departing from the concept of the premise utility, and performance or
Purposes is identical, then shall be regarded as belonging to the protection scope that claims that the utility model is submitted determine.
