Abstract
The invention discloses an air sealing device for an auto motor. The air sealing device comprises a shell, a rotor of the auto motor and a stator of the auto motor, wherein the rotor is arranged on the stator; a front end cover is arranged on the shell at the side where the stator and the rotor are arranged; a breather pipe is arranged on the front end cover and is provided with a breather pipe connector; compressed air fills the space between the front end cover and the stator and between the front end cover and the rotor. Therefore, with adoption of the air sealing device, outside mud and dust can be blocked from entering the inside of the motor, thus ensuring the safe running of the motor and prolonging the service life.
Description
Technical field
The present invention relates to a kind of improvement of electric motor of automobile sealing device, particularly a kind of muddy water of outside motor and sand and dust of making cannot enter inside, thereby have ensured the safe operation of motor and the air seal of life-extending electric motor of automobile.
Background technology
Automobile drive electric motor, in vehicle traveling process, due to road conditions complexity, often has muddy water, sandstone or dust to trickle down on motor, and between motor-shaft extending end and end cap, has relative motion, has gap. Motor when operation muddy water and sand and dust probably by the motor internal that enters here, cause oil sealing, bearing or other parts to wear and tear, have a strong impact on service life and the security performance of motor.
Conventional motors structure is by mounting framework sealing ring (oil sealing), isolated outside silt, dust and greasy dirt, but due to the running environment complexity of electric motor of automobile, common material backbone sealing ring is low service life, and protection effect is poor. Need to be with special backbone sealing ring customized, but under severe operating mode, also difficulty reaches ideal effect.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of muddy water of outside motor and sand and dust of making cannot enter inside, thereby has ensured the safe operation of motor and the air seal of life-extending electric motor of automobile.
For solving the problems of the technologies described above, the air seal that technical scheme is a kind of electric motor of automobile that the present invention adopts, comprising: the rotor of housing, electric motor of automobile and the stator of electric motor of automobile; Described rotor is arranged on stator; A side that is positioned at stator and rotor on described housing is provided with drive end bearing bracket; Described drive end bearing bracket is provided with breather pipe; Described breather pipe is provided with gas-tpe fitting; Between described drive end bearing bracket and stator and rotor, be filled with compressed air.
Preferably, described gas-tpe fitting is bent tube type gas-tpe fitting.
The invention has the beneficial effects as follows: the air seal of a kind of electric motor of automobile of the present invention, by at motor internal using charged air pressure, make motor internal pressure higher than external pressure, can make muddy water and the sand and dust of outside motor cannot enter inside, thereby ensure the safe operation of motor and life-extending.
Brief description of the drawings
The structural representation of the air seal that accompanying drawing 1 is a kind of electric motor of automobile of the present invention;
Wherein: 1, breather pipe; 2, bent tube type gas-tpe fitting; 3, drive end bearing bracket; 4, rotor; 5, stator.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, the embodiment of the present invention comprises:
For solving the problems of the technologies described above, the air seal of a kind of electric motor of automobile of technical scheme that the present invention adopts, comprising: the rotor 4 of housing, electric motor of automobile and the stator 5 of electric motor of automobile; Described rotor 4 is arranged on stator 3; A side that is positioned at stator 5 and rotor 4 on described housing is provided with drive end bearing bracket 3; Described drive end bearing bracket 3 is provided with breather pipe 1; Described breather pipe 1 is provided with gas-tpe fitting 2; Described gas-tpe fitting 2 is bent tube type gas-tpe fitting 2; Between described drive end bearing bracket 3 and stator 5 and rotor 4, be filled with compressed air. Described breather pipe 1 can be arranged on the position such as end cap or terminal box of motor; By passing into compressed air at motor internal, compressed air enters motor internal through breather pipe 1 road, due to the hermetically-sealed construction of motor internal itself, make motor interior form positive pressure air, motor internal and outside motor have formed a pressure differential, motor internal pressure is higher than external pressure, form an airtight seal structure, thereby stop that outside muddy water and sand and dust enter motor internal, outside muddy water and sand and dust cannot enter inside, ensure the safe operation of motor and life-extending, and arrived the degree of protection of IP67.
The invention has the beneficial effects as follows: the air seal of a kind of electric motor of automobile of the present invention, by at motor internal using charged air pressure, make motor internal pressure higher than external pressure, can make muddy water and the sand and dust of outside motor cannot enter inside, thereby ensure the safe operation of motor and life-extending.
Below be only concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation. All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on rights protection scope of the present invention.
Claims (2)
