Description
Technical field
The utility model relates to the Motor Vehicle component, concrete is the starter motor of Motor Vehicle.
Background technique
Nearly all Motor Vehicle all is equipped with starter motor at present, and because of the purposes difference, vehicle is different, just present the starter motor of all size and all styles of, however at present general starter motor because brush spring is made by cast iron, volume is inevitable very big, weight is also heavier, and the precision of making is corresponding also low.Brush spring is packed into again and is stretched in the back cover cap that forms by the thick steel plate of 1mm, like this, following is exactly because of the unusual heaviness of complex structure complete machine, install loaded down with trivial details, use inconvenience, starter shaft rotates in the cast iron brush spring for a long time, and the wall of back cover cap is very thin again, the machine life of starter motor nature is just low like this, and reliability is also poor.Be cast iron from manufacturing the angle brush spring simultaneously, whole production process is comparatively complicated, at first need to make die model, want molding modeling then, then reprocess blank, carry out the assembling of part etc. at last, whole production technology is very complicated, not only takes a lot of work but also time-consuming certainly, must waste some raw material, also wasted the energy accordingly,, thereby brought suitable adverse factors to environmental protection because casting is the chief component of operation, and noise pollution also can't neglect, the cycle of producing is long, and power consumption is big, and the cost height is some problems of appearance thereupon in the at present general starter motor production process.
Summary of the invention
The purpose of this utility model is loaded down with trivial details in order to solve at present general starter motor complex structure, heaviness, making, takes a lot of work, time-consuming, the problem that wastes energy and provide simple in structure, light, make and be easy to a kind of motor vehicle starter.
The technological scheme that adopts is:
A kind of motor vehicle starter comprises back cover cap, brush spring assembly, front cover, starter shaft; Described starter shaft is installed in the housing, is equiped with armature assembly on the starter shaft, and the housing internal fixation has stator assembly, and a side of housing is provided with the magnetic switch assembly, and an end of magnetic switch assembly is connected by bolton with front cover.Its structural feature is:
Described back cover cap is provided with ear end face, the front end of back cover cap is provided with bayonet socket, the inner installing of back cover cap one axle bush seat, and the bottom of axle bush seat is provided with the bottom surface, axle bush seat bottom surface links into an integrated entity by punching press with the ear end face of back cover cap, and the center of circle, axle bush seat bottom surface coincides with the ear end face center of circle of back cover cap.
Described brush spring assembly comprises four brush holders, brush holder base plate, four brushes, and four brush holders are fixed on the edge of brush holder bottom center hole symmetrically, and the brush holder base plate is installed in the cover cap front end bayonet socket of back and between the ear end face of housing, and is fastenedly connected by screw.
Be equiped with axle bush in the mesopore of above-mentioned axle bush seat.
The top of above-mentioned four brush holders fixedly is equiped with brush respectively.
The utility model is to improve on the basis of having excavated the blemish in an otherwise perfect thing that starter motor exists in actual applications, has carried out rational design, and complete machine structure is simple and rigorous, embodied the principal advantages that a kind of motor vehicle starter has:
One, adopt new technology and make and assemble:
Adopt the cold-rolling and punching interconnection technique on the technology, what cover cap cooperated with the axle bush seat after making closely and not can come off and be out of shape, and the punching press Placement also becomes anti-counterfeiting mark of the present utility model.
Two, save raw material, saved the energy:
Brush spring adopts the thick Drawing Steel plate stamping and forming of 2mm, and volume reduces relatively, and length is also than the about 10mm of original shortening, and weight saving about 150 restrains, thereby has saved great deal of raw materials, has saved the energy accordingly.
Three, technical performance is strengthened:
Since adopted cold rolled sheet, more reliability and durability than cast iron on intensity.Front cover is that the fine metal mould by the production of machining carries out the blank that precision casting goes out and forms with numerically controlled lathe fine finishing, and surface accuracy is greatly improved, and the complete machine precision also promotes significantly, to such an extent as to can compare favourably with aluminum casting.Stability, reliability, the Security of complete machine operation are significantly strengthened.
Four, improved working efficiency:
Simplifying of the manufacturing process that complete machine is manufactured saved man-hour, saved manpower, and cost of production reduces greatly, improved working efficiency.
Five, environment purification, reduce and pollute:
The production technology of brush spring reforms the new process of Drawing Steel plate stamping and forming into by die model, founding, the casting in past, has purified environment, has reduced pollution.The utility model is applicable to that Motor Vehicle uses.
Need to prove that under the prerequisite that does not change principle of the present utility model and design, can also make some changes or distortion to the utility model, this belongs to protection domain of the present utility model equally.
