Abstract
The invention discloses a front end cover of a generator. The front end cover includes an end cover body. Hanging horns, end cover installation holes, a protective cover and a shaft hole are arranged on the end cover body. A plurality of extension arms, which are installed on the protective cover, are arranged at the outer side of the shaft hole. Connection holes, positioning holes and the end cover installation holes are arranged in the extension arms. The two hanging horns are also arranged on the end cover body. Each hanging horn is provided with a hanging horn hole. Reticular heat dissipation holes are evenly distributed in the protective cover. The end cover body and the extension arms are formed integrally and are aluminum-alloy castings. The front end cover of the generator effectively improves the assembly strength of the generator, increases the use reliability of the generator and comparatively convenient to dismount.
Description
Technical field
The present invention relates to a kind of automobile current generator accessory, particularly a kind of front end of shield.
Background technology
Generator is the plant equipment that the energy conversion of other form is become to electric energy, and electric generators for automobile is the main power source of automobile, and its function is in the time of normal working of engine, to all power consumption equipment power supplies except starter motor, charges a battery simultaneously; Conventionally generator front and back end is that front end housing and rear end cap are assembled together, and front end housing and rear end cap play a part support rotor, stator, rectifier and brush assembly of electric.Current front end housing protective cover has many louvres, and protective cover central authorities have axis hole, and this directly causes the axis hole insufficient strength that coordinates with bearing cap, rotor on front end housing large, has affected the use of generator.
Summary of the invention
The object of the invention is to overcome existing a kind of front end of shield upper shaft hole in prior art coordinates insufficient strength large with bearing cap, rotor, easily cause the stress of front end housing protective cover to concentrate, affect the deficiency of the use of engine, a kind of front end of shield is provided, this one front end of shield simplicity of design, coordinate the reliability that intensity is higher, improved generator with bearing cap, rotor, and location is convenient, dismounting is quick.
In order to realize foregoing invention object, the invention provides following technical scheme:
A kind of front end of shield, comprises end cap body, and described end cap body is provided with hangs angle, end cap installing hole, protective cover and axis hole, and described axis hole outside is provided with the some adjutages that are arranged on described protective cover, and described adjutage is provided with connecting hole.
In the middle of protective cover by end cap body, arrange on adjutage, connecting hole is arranged on adjutage again, front end housing and bearing cap, rotor is assembled together with bolt, and the installation strength of front end housing is significantly improved, and generator uses more reliable.
Preferably, described adjutage is four, and is evenly distributed on described protective cover.
Preferably, described adjutage is provided with location hole.
The location hole arranging on adjutage, is when front end housing is assembled on generator, location more fast and accurately, and dismounting also will be more convenient.
Preferably, described adjutage extends to protective cover end face, and described end cap installing hole is arranged on adjutage.
Adjutage is extended to protective cover end face, and end cap installing hole is arranged on adjutage, has indirectly increased the thickness of protective cover, and equally distributed end cap installing hole is assembled to front end housing on generator by bolt, has also improved the installation strength of front end housing.
Preferably, described end cap body is provided with two and hangs angle, and wherein each extension angle is provided with Gua Jiao hole.
Preferably, on described protective cover, be evenly distributed with netted louvre.
Preferably, described end cap body and described adjutage are one-body molded, and are aluminium alloy castings.
It is more easy that integrated end cap body is made, and improved manufacture efficiency.
compared with prior art, beneficial effect of the present invention:
A kind of front end of shield of the present invention, by adjutage is set in the middle of end cap body protective cover, on adjutage, be provided with connecting hole, location hole and end cap installing hole, together with again the axis hole of front end housing being passed through to bolts assemblies with bearing cap, rotor, not only improve assembling intensity, and location is more accurate, dismounting fast; On adjutage, connecting hole, end cap installing hole are uniformly distributed simultaneously, and the erection stress having reduced between front end housing and rotor is concentrated, the useful life of having improved generator.
