In the working region of metal tape operation outside the gases at high pressure discharge speed changer that the operation of fast device generates, since the high speed of steel band is transported
Turn, the oil gas of larger high temperature and pressure can be generated.In the metal tape working region arranging exhaust air structure, a high pressure gas is easy to really
Outside body discharge speed changer, but the oil gas inside speed changer can also be discharged simultaneously, lead to the problem of bleed.
（2）Normally closed type exhaust structure is arranged in steel band operation area, is opened when speed changer air pressure inside reaches certain value,
Otherwise close.The exhaust structure designs, after gearbox oil temperature reduces or speed changer cools down, due to normally closed type breather plug knot
Structure, cause condensation vapor in speed changer inner air inside housings or the components such as gear on, and then cause in speed changer
Portion's part gets rusty phenomenon, influences the service life of speed changer.

Specific embodiment
The utility model is described in further detail for explanation and specific embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 to 6, a kind of automatic transmission exhaust structure, including case of transmission 1 and with the transmission case
The clutch housing 6 that body 1 connects is equipped with labyrinth cavity 5, the speed changer between the case of transmission 1, clutch housing 6
Housing 1 is equipped with breather plug 3, and the outlet of the labyrinth cavity 5 is connected with the breather plug 3, is equipped in the case of transmission 1
Driven belt wheel shaft 4, the driven belt wheel shaft 4 are equipped with gear 7 and metal tape 2.
As shown in Figures 1 to 6, the first cavity 8, the second chamber that the labyrinth cavity 5 includes curved arrangement and head and the tail connect
Body 9, the 3rd cavity 10 and the 4th cavity 11, the gear 7 and metal tape 2 are located within first cavity 8, first chamber
Body 8 is located within the case of transmission 1, and second cavity 9, the 3rd cavity 10 are located within the clutch housing 6, institute
It states the 4th cavity 11 to be located within the case of transmission 1, the 4th cavity 11 is connected with the breather plug 3.
As shown in Figures 1 to 6, a similar labyrinth being made up of case of transmission 1, clutch housing 6 and gear 7
Arrangement cavity, the main function of the structure is：Allow the oil gas mixture of buncher internal high temperature, high pressure,
The inside cavity of this labyrinth structure flows as far as possible by multiple deflecting, so most of transmission oil due to temperature and
Density reasons are placed in high pressure mixed gas lower part, Oil-gas Separation are generated, so that the air inside speed changer passes through breather plug
Outside 3 discharge speed changers, and transmission oil is stayed in buncher enclosure interior, reach control speed changer air pressure inside balance
Effect.
As shown in Figures 1 to 6, the movement parts such as metal tape 2 and gear 7 in the operational process of speed changer, generate a large amount of high
Warm high-pressure oil gas mixture reaches the first cavity 8 of case of transmission 1 by arrow direction shown in Fig. 3 and notch, subsequently into
The 3rd cavity 10 of clutch housing 6 is arrived to the second cavity 9 of clutch housing 6, then by the notch of the second cavity 9,
The 4th cavity 11 of case of transmission 1 is entered by the 3rd cavity 10, is discharged finally by breather plug 3 outside case of transmission 1.
The main medium for driving buncher work is transmission oil.Inside buncher, transmission oil passes through
Enclosure interior oil duct etc. enters corresponding piston cavity, while also lubricates speed changer internal component.It is provided by the utility model
A kind of automatic transmission exhaust structure, by the specific labyrinth structure form of housing design, quickly inside buncher
While the oily gentle separation of high temperature and pressure, outside air discharge speed changer, ensure the normal operation of speed changer, improve speed change
