Technical field
Wheel is discharged the utility model is related to Trailer car shaft more particularly to by the lubricating oil fog in the shaft end wheel hub cavity of axle
The lubricating oil fog exhaust system of hub chamber.
Background technology
The lubricating system of Trailer car shaft has two kinds of grease lubrication and oil lubrication.Glossy pulley axle, which has, lubricates abundant, heat dissipation
The advantages that property is good is widely used.But glossy pulley axle is in the driving process of vehicle, because of bearing rotation and braking
The reasons such as frictional heating can cause the lubricating oil thermal expansion in wheel hub cavity to be gasified and generate oil gas mist of oil, and oil gas mist of oil must be timely
Wheel hub is discharged, the raising of wheel hub cavity pressure otherwise can be caused to generate oil accident.For this purpose, the prior art is installed on wheel hub end housing
One rubber porous plug, the oil gas mist of oil that wheel hub cavity internal heat generation generates discharge wheel hub cavity by the rubber porous plug.Such row
There are following defects for depressed structure：1st, rubber porous plug is easily blocked so as to make wheel hub cavity pressure excessively high and oil leak；2nd, it arranges
The oil gas mist of oil gone out easily adsorbs dust on end cap causes wheel hub end face dirty；3rd, outside moisture and dust, which have, passes through venting plug
Into the risk of wheel hub cavity pollution lubricating oil.
Utility model content
The purpose of this utility model is to provide a kind of lubricating oil fog exhaust system of axle hub chamber, above-mentioned existing to overcome
There is the defects of technology.
The another object of the utility model is to provide a kind of lubricating oil fog exhaust cap of axle hub chamber, which uses
In the lubricating oil fog exhaust system.
The utility model is realized in this way：The lubricating oil fog exhaust cap of axle hub chamber, including a cover, cover
Equipped with the gas vent through cover both ends end face.
Preferably, the exhaust plug covered on the gas vent is equipped in a side end face of the cover, exhaust plug is set
There are the exhaust passage of detour, exhaust passage and the gas vent unicom.
Preferably, the exhaust plug is made of oil resistant rubber or oil resistant plastics.
Preferably, the exhaust plug is Nian Jie with the cover.
Preferably, the exhaust plug is equipped with valve core cap, and valve core cap is covered deviates from the row in the exhaust plug
On one side end face of stomata.
Preferably, the periphery of the cover, which turns down, to form skirt and encloses, and the peripheral surface that skirt encloses is bonded with oil resistant rubber layer.
Preferably, the outer surface of the oil resistant rubber layer has multi-turn bulge loop.
The lubricating oil fog exhaust system of axle hub chamber described in the utility model, including axle and mounted on axle end
The wheel hub in portion, the end of axle have stomidium, and wheel hub is equipped with the wheel hub cavity being sealed to form by wheel hub end housing, in the stomidium of axle
Exhaust cap is stamped, which is exactly lubricating oil fog exhaust cap described in the utility model, the week of lubricating oil fog exhaust cap
Side and the inner wall tight fit of the stomidium.
Preferably, the exhaust plug of the lubricating oil fog exhaust cap is located at the side towards wheel hub cavity of the exhaust cap.
The utility model has the advantages that the oil gas mist of oil in 1, wheel hub cavity is discharged by the exhaust cap in axle, it will not
Dirty wheel hub end face；2nd, compared with the rubber porous plug that the prior art uses, it is vented more unobstructed, the risk not being blocked；4、
Oil gas mist of oil can discharge wheel hub cavity in time by the exhaust cap, and the risk that outside moisture and dust enter wheel hub cavity subtracts significantly
It is few.
Description of the drawings

Fig. 2 is the structure diagram of the embodiment of lubricating oil fog exhaust cap described in the utility model；
Fig. 3 is the right view of the exhaust plug in Fig. 2；
Fig. 4 is the A portions enlarged drawing of Fig. 2.
Specific embodiment
The lubricating oil fog exhaust system of axle hub chamber is as shown in Figure 1, including axle 1 and mounted on 1 end of axle
Wheel hub 2, the end of axle 1 have stomidium 3, and wheel hub 2 is equipped with the wheel hub cavity 5 being sealed to form by wheel hub end housing 4.In 3 inner cover of stomidium
There is exhaust cap 6, which is exactly lubricating oil fog exhaust cap shown in Fig. 2, and the periphery of exhaust cap 6 and the inner wall of stomidium 3 are tight
Cooperation so that exhaust cap 6 is clamped securely in stomidium 3.
Referring to Fig. 2, lubricating oil fog exhaust cap 6 includes a cover 7, and cover 7 can use metal stamping formed or machining
Molding, cover 7 are equipped with the gas vent 8 through cover both ends end face.It is equipped with and is covered on gas vent 8 in a side end face of cover 7
Exhaust plug 9, exhaust plug 9 are equipped with the exhaust passage 10 of detour, exhaust passage 10 and 8 unicom of gas vent.Profit shown in Fig. 1
In lubricating oil fog exhaust system, exhaust plug 9 is located at the side towards wheel hub cavity 5 of exhaust cap 6.The exhaust passage 10 of detour
Effect is that the oil gas mist of oil in wheel hub cavity 5 is only allowed to enter in axle 1 by gas vent 8, hinders the liquid state profit in wheel hub cavity 5
Lubricating oil flows into axle 1 by gas vent 8, even if there is a small amount of liquid state lubricating oil to enter exhaust passage 10, can also be vented
Collect in channel 10 and flow back to wheel hub cavity 5.Exhaust plug 9 is be bonded with cover 7.Exhaust plug 9 is preferably by oil resistant rubber or oil resistant
Plastics are made.In order to avoid collecting excessive liquid state lubricating oil in exhaust passage 10, and preferably hinder in wheel hub cavity 5
Liquid state lubricating oil pass through cover 7 through gas vent 8, exhaust plug 9 is equipped with valve core cap 11, and valve core cap 11 is covered in air bleeding valve
Core 9 on a side end face of gas vent 8.
As preferred forms, referring to Fig. 2, the periphery of cover 7, which turns down, to be formed skirt and encloses 12, and skirt encloses 12 peripheral surface bonding
There is oil resistant rubber layer 13.May be such that in this way cover 7 periphery and Fig. 1 shown in stomidium 3 inner wall cooperation it is closer, make exhaust cap 6
Fix more firm, and enhance leakproofness in the stomidium 3 of axle, it is ensured that the lubricating oil in wheel hub cavity 5 will not pass through exhaust cap 6
Periphery penetrate into axle 1 in.Further, as shown in figure 4, the outer surface global formation of oil resistant rubber layer 13 has multi-turn bulge loop
14, the cooperation tight ness rating of oil resistant rubber layer 13 and stomidium 3 can be further enhanced in this way, increase leakproofness.
