Abstract
The utility model discloses the longitudinal few shift transmission ventilation device of one kind, it includes rear shell, fore shell, barricade, ventilation plug sleeve and breather plug cover；The barricade on shell top can effectively stop the splash lubrication oil that gear is stirred afterwards, and whole aerating system path is longer and complications, the oil gas condensation that few part can be bypassed into barricade gets off, and effectively prevent lubricating oil and is leaked from breather plug, and with good ventilatory effect.
Description
Technical field
The utility model, which is related to, belongs to electric vehicle transmission technical field, more particularly to a kind of longitudinal few shift transmission ventilation
Structure.
Background technology
With oil consumption and the requirement more and more higher of emission request, the development speed of hybrid power and electric car is exceedingly fast.By
In the working characteristics of motor, transmission gear digit can be reduced, and few shift transmission has wide application empty in new energy field
Between.
Currently for pure electric vehicle, a shift transmission, i.e. decelerator are extremely widespread using very wide.But due to current motor
One gear of technical merit is difficult it has been given play to optimum capacity, so few shift transmission is the best match of electric car at this stage
Selection.
Few shift transmission is shorter due to length, it is difficult to go out longer, the more tortuous gas channel of stroke in single housing design,
So permeability risk is larger.So it is accomplished by designing a set of special aerating system in this structure, it is ensured that speed changer is ventilated
It is smooth and oil-tight.
Utility model content
The utility model purpose is to provide a kind of longitudinal few shift transmission ventilation device, Ju have the mono- ﹑ of Jie structures Jian be easy to assembling,
The features such as performance stabilization and good ventilatory effect.
The utility model solves technical problem and adopted the following technical scheme that：A kind of longitudinal few shift transmission ventilation device, its
Including rear shell, fore shell, barricade, ventilation plug sleeve and breather plug cover；
Square boss is formed with the rear shell, through hole is formed with along the short transverse of the boss；
The front end of the barricade and the front side wall of the boss are cast integrally, and parallel to the left side wall of the boss,
There is a preset distance between the lower wall of the lower end of the barricade and the boss；And the bottom of the barricade with it is described after
Shell is cast integrally；
Opening on the rear shell is connected with the space between the right side wall of the barricade and the boss；
Rear shell airway, one end and the barricade and the boss of the rear shell airway are formed with the rear shell
Space connection between left side wall；
Fore shell airway is formed with the fore shell, the fore shell airway includes horizontal segment and vertical section, the level
Section is connected with vertical section one end, and is mutually perpendicular to；The other end of the other end of the horizontal segment and the rear shell airway connects
It is logical, the other end and atmosphere of the vertical section；
The ventilation plug sleeve is fitted on fore shell, and in the vertical section, the breather plug cover is stuck in breather plug
On sleeve pipe.
The utility model has the advantages that：In the utility model, the oil gas that transmission gear is stirred is through shell later
On barricade after, change flow direction, into rear shell airway, rear shell airway is connected with fore shell airway, the long air flue of formation,
It is easy to oil gas condensation；And in fore shell, the fore shell airway includes horizontal segment and vertical section so that the oil gas side of change herein
To, oil gas condensation ability is increased, changes the air flue behind direction straight up, and it is longer, condensing capacity is lifted, ventilation sleeve pipe is mounted in
On fore shell, breather plug cover is stuck on ventilation sleeve pipe, and breather plug cover is protected together as the last of whole aerating system, it is ensured that whole
The performance of system and stably.

Embodiment 1
Present embodiments provide a kind of longitudinal few shift transmission ventilation device, including rear shell, fore shell, barricade, ventilation plug sleeve
Pipe and breather plug cover.
Square boss is formed with the rear shell, through hole is formed with along the short transverse of the boss, the barricade
Front end and the front side wall of the boss are cast integrally, and parallel to the left side wall of the boss, the lower end of the barricade and institute
Stating has a preset distance between the lower wall of boss；And the bottom of the barricade is cast integrally with the rear shell；
Rear shell airway, one end and the barricade and the boss of the rear shell airway are formed with the rear shell
Space connection between left side wall.
Fore shell airway is formed with the fore shell, the fore shell airway includes horizontal segment and vertical section, the level
Section is connected with vertical section one end, and is mutually perpendicular to；The other end of the other end of the horizontal segment and the rear shell airway connects
It is logical, the other end and atmosphere of the vertical section, and it is provided with ventilation plug sleeve and breather plug cover.
That is, described ventilation plug sleeve is fitted on fore shell, and in the vertical section, the breather plug cover is stuck in ventilation
On plug sleeve.
Opening on the rear shell is connected with the space between the right side wall of the barricade and the boss, and causes rear shell
The barricade on top can effectively stop the splash lubrication oil that gear stirs, and whole aerating system path is longer and complications, energy
The oil gas condensation that few part is bypassed into barricade gets off, it is the worst in the case of, some operating modes have oil gas by whole airway,
It can be blocked by last breather plug cover, prevent oil gas from oozing out, both ensure that ventilatory effect, be also not in oil leakage problem.
In the present embodiment, the oil gas that transmission gear is stirred changes flow direction, after after the barricade on shell later
Shell airway, rear shell airway is connected with fore shell airway, is formed long air flue, is easy to oil gas condensation；And in fore shell, it is described
Fore shell airway includes horizontal segment and vertical section so that oil gas changes direction herein, increases oil gas condensation ability, changes behind direction
Air flue straight up, it is and longer, lift condensing capacity, ventilation sleeve pipe is on fore shell, and breather plug cover is stuck on ventilation sleeve pipe,
Breather plug cover is protected together as the last of whole aerating system, it is ensured that the performance of whole system and stably.
For ease of description, the quality of embodiment is not only represented for the sequencing of above example.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：
