Description
Technical field
The utility model relates to vehicle transmissions, and in particular to a kind of drive axle breather plug.
Background technique
Traditional drive axle breather plug or structure is complicated, higher cost or structure are simple, but reliability is bad, leads to
While gas, the oil vapour in drive axle cannot be effectively sealed, leads to that permeability, oil leakage phenomenon occur at rear axle ventilation plug.Driving
Bridge breather plug is covered in driving axle housing, is often provided with the structures such as brake pipe, suspension part, narrow space, driving herein
The arrangement of bridge breather plug can be very inconvenient.
Conventional ADS driving bridge breather plug is as shown in Figure 1, the drive axle breather plug includes filling in the former cock body 10 of hollow form, with former
Integrally formed original in the top of body 10 cock cap 20 and the claw 30 that is arranged in below former cock body, and the original cock cap 20 is equipped with venthole
40, the claw 30 is interference fitted with drive axle cap, is connected to inside 10 inside of original cock body and drive axle；The original cock body
There are two diaphragms 50 for setting in 10.
In the motion process of gear in drive axle, gear oil temperature is got higher, and forms oil vapour, and oil vapour passes through former plug
Diaphragm 50 can be contacted when 10 inner cavity of body, temperature is reduced and liquefied on diaphragm 50, then stays back in driving axle housing body；Remaining oil
Steam is discharged by venthole 40.
The drive axle ventilation plug structure is more complicated, and production is more demanding, and claw is easy poor sealing, to generate oil leak
Phenomena such as；And the components such as brake pipe, suspension part that driving axle housing covers will cause narrow space, hinder the drive axle
The arrangement of breather plug.
Summary of the invention
The purpose of the utility model is to provide a kind of drive axle breather plug, to solve to be easy oil leak and narrow space, no
The problem of easily arranging.
To realize the above-mentioned technical purpose, the scheme that the utility model uses is as follows:
A kind of drive axle breather plug, including cock body and with the integrally formed cock cap in cock body upper end, the cock body be strip,
The lower end of the cock body has a cylindrical bending part extended to the right, sets that there are two convex annulars on the side wall of the bending part
It rises, forms positioning ring groove between two annular protrusions；The bending part and Driving axle housing are cooperatively connected and make Driving axle housing
It is connected in positioning ring groove；Venting cavity is offered inside the cock body, the right side of cock body upper end side wall is thinner than left side,
And joint-cutting is offered on the right side of its side wall, the joint-cutting is connected to venting cavity upper end.
The venting cavity upper end is covered and is passed through by cock cap and is connected to outside joint-cutting and Driving axle housing, the venting cavity lower end
It is connected to Driving axle housing inside.
The cock body is rubber component.
The right end edge of the bending part is equipped with chamfering.
The utility model has the beneficial effects that: (1) since the utility model is L-shaped and can rotate, material ratio
It is softer, the problem of enabling the utility model to avoid other components, be not in insufficient space；(2) due to venting cavity ratio
Longer, oil vapour has enough room and times to be liquefied and is flowed back during being displaced outwardly；(3) due to venting cavity ratio
It is longer, and venting cavity utilizes joint-cutting and external connection, avoids oil liquid and is discharged by venting cavity；(4) due to use joint-cutting and
Stopper cap structure, so that the waterproof of the utility model and anti-foreign matter performance are good；(5) since the utility model utilizes the elasticity of rubber parts
And be clamped using positioning ring groove, it is not in gap that installation is very convenient；(6) since the utility model structure is simply and by rubber
Glue is made, also without the structure of the complexity such as diaphragm, claw, thus it is easy to process, cost is relatively low.
Detailed description of the invention
Fig. 1 is background technique drive axle breather plug schematic diagram；
Fig. 2 is schematic structural view of the invention；
Fig. 3 is the sectional view along A-A of Fig. 2.
Label in figure respectively indicates: 1- cock body, 2- cock cap, 3- bending part, 4- annular protrusion, 5- positioning ring groove, and 6- is logical
Air cavity, 7- joint-cutting, 8- chamfering, 10- original cock body, 20- original cock cap, 30- claw, 40- venthole, 50- diaphragm.
Specific embodiment
It is right with reference to the accompanying drawings and examples in order to make those skilled in the art that the utility model may be better understood
Technical solutions of the utility model further illustrate.
As shown in Fig. 2, a kind of drive axle breather plug, including the cock body 1 made of rubber component and with 1 upper end of cock body one
Molding cock cap 2, the cock body 1 are strip, and the lower end of the cock body 1 has a cylindrical bending part 3 extended to the right,
It is set on the side wall of the bending part 3 there are two annular protrusion 4, forms positioning ring groove 5 between two annular protrusions 4；The bending
Portion 3 and Driving axle housing are cooperatively connected and are connected to Driving axle housing in positioning ring groove 5；It is offered inside the cock body 1 logical
The right side of air cavity 6, the 1 upper end side wall of cock body is thinner than left side (as shown in Figure 3), and opens up on the right side of its side wall
There is joint-cutting 7, the joint-cutting 7 is connected to 6 upper end of venting cavity.
6 upper end of venting cavity is covered by cock cap 2 and by being connected to outside joint-cutting 7 and Driving axle housing, the venting cavity 6
It is connected to inside lower end and Driving axle housing.
The right end edge of the bending part 3 is equipped with chamfering 8.
Due to existing Driving axle housing be equipped with the connecting hole for being connect with breather plug (i.e. in background technique with claw
The hole of 30 interference fits), when the utility model is used, bending part 3 is directly filled in into Driving axle housing using the elasticity of rubber parts
Connecting hole in installation can be completed, very convenient, flexible positioning ring groove 5 can closely cooperate with Driving axle housing,
It is not in gap.
Venting cavity 6 is entered by the lower end of venting cavity 6 after generation oil vapour in drive axle, and is arranged by the upper end of venting cavity 6
Out.The upper end that cock cap 2 covers venting cavity 6 can prevent water and foreign matter from entering.Since the utility model is elongated, so that ventilation
Chamber 6 is long, and general length is 50mm or more, and oil vapour has enough room and times to carry out liquid during being displaced outwardly
Change and flow back, ensure that liquefaction amount, also can be avoided after pressure increases and extrude oil liquid.
It is and cylindrical at the cooperation of Driving axle housing since cock body 1 is L-shaped, so cock body 1 can be rotated,
To adjust its position, thus the problem of avoiding other components, being not in insufficient space, since cock body 1 is relative to metal ratio
It is softer, further improve its flexibility.
Oil vapour is generated in drive axle increases 6 air pressure inside of venting cavity, and oil vapour is discharged by joint-cutting 7.Due to using
The form of joint-cutting, when not having draught head, oil vapour and oil liquid can not have the discharge of joint-cutting 7, further avoid oil leakage phenomenon, together
When, relative to the mode of aperture, the waterproof of joint-cutting and the effect of foreign matter are more preferable.
It the utility model relatively simple for structure and is made of rubber, also without the structure of the complexity such as diaphragm, claw, therefore just
In processing, cost is relatively low.
