It is logical.
The present invention also provides a kind of method for exhausting of flush type ventilation plug structure, the oil gas of the clutch inner cavity generation
Mixture enters in venting plug by air flue, and gas mixture is carried out Oil-gas Separation by breather plug, and the gas after separation is by logical
The outlet side of vent plug enters in embedment hole, then is discharged into the inner cavity of clutch by gas vent, finally passes through the stomata of clutch
It is discharged into atmosphere；The oil of breather plug separation is back in the inner cavity of speed changer by air flue.
Compared with prior art, the invention has the following beneficial technical effects:
A kind of flush type ventilation plug structure provided by the invention, breather plug are mounted on the embedment hole of clutch housing outer wall
In, which uses enclosed construction, prevents rainwater or dust from entering around breather plug.Inside speed changer oil gas by air flue into
Enter breather plug, is discharged into the inner cavity of clutch using the gas vent in embedment hole, the stomata and ambient atmosphere on clutch inner cavity
It is connected, the clutch inner cavity enclosure space, the dust impurity of air is less in inner cavity, it is not easy to form grease or blocking breather plug,
It can effectively solve the problems, such as that time service leads to blocking on breather plug, can make speed changer appearance neat and artistic, it is ensured that breather plug
Reliability is improved customer satisfaction.
It is further closed using blanking cover by hole is embedded to, convenient for safeguarding or replacement breather plug reduces maintenance cost.
Further air flue uses horizontal through hole structure, and is sealed one end using plug, easy to process, reduce manufacture at
This.
The present invention also provides the method for exhausting of above-mentioned flush type ventilation plug structure, the gas mixture in gearbox passes through
Air flue enters breather plug, by breather plug carry out Oil-gas Separation after, by be embedded to hole side wall by the gas after separation spray into from
In clutch cavity, isolated oil is back in gearbox by air flue；Gas is sprayed from clutch housing, is avoided and extraneous ash
Dirt contact, therefore not will cause the problem of breather plug blocks.
Detailed description of the invention
Fig. 1 is the mounting structure schematic diagram of breather plug of the present invention.
In figure: 1, breather plug；2, blanking cover；3, clutch housing；4, clutch housing and engine faying face；5, it is vented
Hole；6, plug.
Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings, described to be explanation of the invention rather than limit
It is fixed.
As shown in Figure 1, a kind of flush type ventilation plug structure, including clutch housing 3 and breather plug 1, clutch housing 3
One end is connect with speed changer main casing, and the other end is connect with engine, and breather plug 1 is arranged on clutch housing 3, and is located at
On partition wall between clutch cavity and variator cavities, which is located on clutch housing 3.
Embedment hole is provided on the partition wall, the depth for being embedded to hole is greater than the height of breather plug, and the bottom for being embedded to hole is provided with
Breather plug mounting hole, the bottom for being embedded to hole are additionally provided with air flue, and one end of air flue is connected to the inner cavity of gearbox, air flue it is another
