Description
Technical field
The utility model relates to drive axle technical field, in particular to a kind of drive axle breather plug and the use drive axle are logical
The drive axle of vent plug.
Background technique
While the car is driving, the rotation of gear, bearing can generate heat, so that the confined space pressure of drive axle increases
Greatly, breather plug is at this moment needed to prevent gear oil seepage etc. to carry out pressure release.Existing breather plug mainly has outside cylindrical full rubber
Add metal cap, be easy to when this breather plug is in automobile wading into water, so as to cause gear oily pollution, so that oil degenerates.
Utility model content
The purpose of the utility model is to provide a kind of waterproof and dustproof performance more preferably drive axle breather plug and use the drive
The drive axle of dynamic bridge breather plug.
In order to realize above-mentioned purpose of utility model, a kind of drive axle breather plug of the utility model and drive axle use as follows
Technical solution:
A kind of drive axle breather plug, including the fixing seat being welded on the upside of Driving axle housing, fixing seat upside and breather plug
Connection, breather plug includes vertical tube, is enclosuring structure at the top of the vertical tube, and the vertical tube is equipped with multiple straight tubes close to top position,
Straight tube is connect with snorkel, and described snorkel one end is socketed in straight tube, and the port size of the snorkel other end is less than straight tube
Port size.The gas outlet of snorkel is arranged to small end mouth, effectively reduces water or dust enters in drive axle, reduce
Influence to oil；Due to the diminution of air outlet, so multiple snorkels are arranged for outlet, to guarantee drive axle internal pressure
Power can timely and effectively release.
The snorkel is rubber hose.Rubber hose can make the gas outlet of snorkel towards vehicle traveling direction phase
Anti- side effectively reduces dust and enters drive axle.
Tapped through hole is provided in the middle part of the fixing seat, Driving axle housing and fixing seat welding position are provided with and fixing seat screw thread
The through-hole that through-hole matches.The vertical tube lower end outer wall is equipped with the screw thread to match with fixing seat tapped through hole.Breather plug and fixing seat
Between connected by threaded screw bore, facilitate the dismounting and change of snorkel.
It is connected with gas-guide tube on the downside of the fixing seat, the gas-guide tube includes vertical pipe and the tipping tube that tilts down, institute
It states vertical pipe and tipping tube is integrally formed, the tipping tube is tilted to drive axle reducer assembly heteropleural, the vertical pipe upper end
Equipped with the screw thread being connect with fixing seat tapped through hole.Gear oil splashes when the setting of gas-guide tube can prevent drive axle internal gear from rotating
It is splashed into breather plug.
The utility model also provides a kind of including Drive axle housing and using the drive axle of above-mentioned drive axle breather plug.
Compared with prior art, the utility model has the beneficial effects that:
1, the air outlet of the snorkel of the utility model is arranged to small end mouth, effectively reduces water or dust enters
In drive axle, reduce the influence to oil；Due to the diminution of air outlet, so multiple snorkels, which are arranged, is used for outlet, from
And guarantee that pressure energy is timely and effectively released in drive axle.
2, gear oil is splashed into breather plug when the setting of gas-guide tube can prevent drive axle internal gear from rotating, so that breather plug
Will not because of greasy dirt blocking and influence releasing for pressure in drive axle.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of breather plug.
Wherein, 1 drive axle, 2 fixing seats, 3 breather plugs, 31 vertical tubes, 32 straight tubes, 33 snorkels, 34 air outlets, 35 spiral shells
Line, 4 gas-guide tubes, 5 speed reducer assemblies.
Specific embodiment
With reference to embodiment, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Bright the utility model rather than limitation the scope of the utility model, after having read the utility model, those skilled in the art
Member falls within the application range as defined in the appended claims to the modification of the various equivalent forms of the utility model.
As depicted in figs. 1 and 2, a kind of drive axle breather plug, including the fixing seat 2 being welded on the upside of 1 shell of drive axle, Gu
2 upside of reservation is connect with breather plug 3, and breather plug 3 includes vertical tube 31, is enclosuring structure, the vertical tube 31 at the top of the vertical tube 31
Multiple straight tubes 32 are equipped with close to top position, straight tube 32 is connect with snorkel 33, and described 33 one end of snorkel is socketed straight tube 32, institute
The port size for stating 33 other end of snorkel is less than 32 port size of straight tube.The snorkel 33 is rubber hose.The fixation
2 middle part of seat is provided with tapped through hole, and 1 shell of drive axle and 2 welding position of fixing seat are provided with to be led to what 2 tapped through hole of fixing seat matched
Hole.31 lower end outer wall of vertical tube is equipped with the screw thread to match with 2 tapped through hole of fixing seat.It is connected with and leads on the downside of the fixing seat 2
Tracheae 4, the gas-guide tube 4 include vertical pipe and the tipping tube tilted down, and the vertical pipe and tipping tube are integrally formed, described
Tipping tube is tilted to drive axle reducer assembly heteropleural, and the vertical pipe upper end is equipped with the spiral shell connecting with 2 tapped through hole of fixing seat
Line.
The specific work process and principle of the utility model: being welded with fixing seat 2 on the upside of drive axle 1 shell, in fixing seat 2
