Background technology
Passenger vehicle main drive motor causes the running environment of motor own complicated because of bus driving environment difference.In southern china and coastal some areas, precipitation is many, and surface gathered water is serious; Or in the section that urban pavement is repaired, easily produce darker muddy connate water.Passenger vehicle travels under such road conditions, splashes large spray and impacts motor, and shaft extension place, motor front end is subject to spray and impacts, and muddy water pours into backbone sealing ring place.Because spray is with foreign matters such as stronger impulsive force and mixing silts, the movable sealing structure of traditional backbone sealing ring is after being impacted for a long time, and wearing and tearing are accelerated, and silt water infiltrate backbone sealing ring will cause motor failure.
Summary of the invention
To be bus driving have the road surface of ponding to splash silt water in large area to the technical problem that the present invention mainly solves for a long time can impact main drive motor and cause motor failure; There is provided a kind of passenger vehicle main drive motor anti-slime water mechanism, can ensure that motor can stable operation under the bad working environments that surface gathered water is many.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of passenger vehicle main drive motor anti-slime water mechanism, between the drive flange being arranged on motor front end and front end housing, drive flange is fixed on and stretches out on the power transmission shaft of front end housing; The outer wall of described drive flange front end is fixed with protective cover; On described front end housing corresponding described drive flange rear end position on be fixed with front end housing cover plate, be provided with backbone sealing ring between front end housing cover plate and the outer wall of power transmission shaft; The end face of described front end housing cover plate is fixed with a circle drip ring, drip ring hides drive flange and drip ring extends in described protective cover, the drip ring outer wall being positioned at protective cover is provided with a circle annulus, and drip ring leaves gap respectively and between drive flange and protective cover; Described drive flange outer wall has cannelure, between cannelure and described front end housing cover plate, forms cavity; Front end housing cover plate end face in described drip ring is provided with a circle boss, and corresponding boss place, drive flange rear end has breach, the end face of front end housing cover plate and form maze trough between boss inwall and described drive flange.
Preferably, described cannelure is arranged near described front end housing cover plate; The breach of described drive flange rear end is communicated with cannelure; The end face of the side near described protective cover in described cannelure is provided with arc-shaped transition; The end face of described cannelure near front end housing cover plate side is equal with the height of described boss to the distance of front end housing cover plate, leaves gap between drive flange rear end outer wall and boss inwall; Described drive flange rear end and form L-type maze trough between boss and front end housing cover plate end face.
Preferably, described annulus, perpendicular to drip ring outer wall, leaves gap between annulus and protective cover inwall.
Preferably, the side that described drip ring is positioned at power transmission shaft lower end has access hole, and access hole place is provided with the capping of sealing access hole.
The invention has the beneficial effects as follows: the present invention possesses and prevents slime water from entering the function of motor internal under bad working environments; Compact overall structure, occupies little space; Pure mechanical structure, reliability is high; Mechanism adopts contactless structure, does not affect electric efficiency.
