Description
Technical field
The present invention relates to automatic transmission, more particularly to a kind of automatic transmission exhaust structure.
Background technology
In speed changer development process, for the internal high temperature high pressure of balance speed changer in the process of running, it will usually designing and arranging
Depressed structure, ensure the relative equilibrium of speed changer air pressure inside and external pressure.The structure of transmission control air pressure generally just like
Lower two kinds：
（1）Exhaust structure open in usual is disposed about in the speed changer interior zone for being easier to produce high pressure, in time speed changer
Caused by operation gases at high pressure discharge speed changer outside metal tape operation working region, due to running at high speed for steel band, meeting
Produce the oil gas of larger HTHP.In the metal tape working region arranging exhaust air structure, it is easy to gases at high pressure to arrange really
Go out outside speed changer, but the oil gas inside speed changer can also be discharged simultaneously, produce bleed problem.
（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 the condensation vapor in speed changer inner air on the part such as enclosure interior or gear, and then cause in speed changer
Portion's part gets rusty phenomenon, influences the service life of speed changer.
The content of the invention
In order to solve the problems of the prior art, the invention provides a kind of automatic transmission exhaust structure.
The invention provides a kind of automatic transmission exhaust structure, including case of transmission and connect with the case of transmission
The clutch housing connect, is provided with labyrinth cavity between the case of transmission, clutch housing, the case of transmission is provided with
Breather plug, the outlet of the labyrinth cavity are connected with the breather plug, and driven belt wheel shaft is provided with the transmission case body, described
Driven belt wheel shaft is provided with gear and metal tape.
As a further improvement on the present invention, the labyrinth cavity include curved arrangement and head and the tail connect the first cavity,
Second cavity, the 3rd cavity and the 4th cavity, the gear and metal tape are located within first cavity, first cavity
Within the case of transmission, second cavity, the 3rd cavity are located within the clutch housing, the 4th chamber
Body is located within the case of transmission, and the 4th cavity connects with the breather plug.
The beneficial effects of the invention are as follows：By such scheme, by setting labyrinth cavity come separation oil and gas, on the one hand, can
To avoid bleed problem, on the other hand, steam can be discharged, avoids phenomenon of getting rusty.

Embodiment
The invention will be further described for explanation and 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 provided with labyrinth cavity 5, the speed changer between the case of transmission 1, clutch housing 6
Housing 1 is provided with breather plug 3, and the outlet of the labyrinth cavity 5 connects with the breather plug 3, is provided with the case of transmission 1
Driven belt wheel shaft 4, the driven belt wheel shaft 4 are provided 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
State the 4th cavity 11 to be located within the case of transmission 1, the 4th cavity 11 connects 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, flowed as far as possible by multiple deflecting, so most of transmission oil due to temperature and
Density reasons, high pressure mixed gas bottom is placed in, Oil-gas Separation is produced, 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 running of speed changer, produce a large amount of high
Warm high-pressure oil gas mixture, the first cavity 8 of case of transmission 1 is reached by the direction of arrow shown in Fig. 3 and breach, subsequently into
The 3rd cavity 10 of clutch housing 6 is arrived to the second cavity 9 of clutch housing 6, then by the breach 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., corresponding piston cavity is entered, while also lubricate speed changer intraware.One kind provided by the invention
Automatic transmission exhaust structure, by the specific labyrinth structure form of housing design, quickly buncher internal high temperature
While the oily gentle separation of high pressure, outside air discharge speed changer, ensure the normal operation of speed changer, improve speed changer
Service life.
