Abstract
The utility model discloses an inner rotor permanent magnetic wheel hub type motor specially used in an electric vehicle, comprising a casing; wherein, a vehicle hanging bracket, a brake disc, a stator, a rotor, a stator bracket and a rotor bracket are arranged in the casing, a transmission shaft and a fixing member are arranged on the casing, and the stator bracket is arranged on the vehicle hanging bracket. The inner rotor permanent magnetic wheel hub type motor specially used in the electric vehicle enables power transmission and braking devices to be integrated in a wheel hub and the space utilization rate to be improved, and is simple in structure.
Description
Technical field
The utility model relates to a drive motor, specifically relates to an electric vehicle for the inner rotor magnet wheel motor valley.
Background technology
Environmental protection and energy-conservation be the theme of world today development, the application of electric automobile has become trend, but because various reasons such as dynamo battery cause the industrialization of electric automobile can not form so far.Though the motor that has the research and development electric automobile to use both at home and abroad never has desirable motor and puts on market.The external rotor wheel hub motor of electric bicycle use in the market is damping under the spring because suspension frame structure causes it, and motor does not have buffer unit, is unable to undergo high speed vibration, and can not be applied on the electric automobile.
The utility model content
The purpose of the utility model is to provide an electric vehicle for the inner rotor magnet ring valleys motor, the power transmission and the braking means are integrated into the hub, simple structure, improved space utilization.
In order to achieve the above object, the technical scheme of the utility model employing is:
An electric vehicle for the inner rotor magnet ring valleys motor, includes a cabinet, wherein the chassis is provided with a vehicle body mounting brackets, brake disc, a stator, a rotor, a stator and a rotor carrier bracket in said casing is provided with a shaft and a fixed member, said stator bracket hanging bracket on the vehicle body.
The beneficial effect of the utility model is:
The utility model all is incorporated into power transmission and brake apparatus in the wheel hub; It has Duoed deceleration than external rotor electric machine; External rotor electric machine does not have the maximum speed of deceleration device, motor can only reach 1000-1500r/min; The rotating speed of wheel is identical with motor, and external rotor electric machine generally is used on the electric bicycle; And the internal rotor permanent-magnetic wheel hub motor has adopted high speed internal rotor technology, and it has been equipped with the decelerator of fixed drive ratio, and for obtaining higher power density, rotating speed of motor can be up to 10000r/min.
The utility model is an inner rotor motor, employing be compact planetary reducer, internal rotor wheel hub motor, aspect power density, than slow-speed of revolution external rotor electric machine powerful 6 times.And because its rotating speed is high, be equipped with cooling fan, can carry out air blast cooling it.
The utility model has been simplified the mechanical part of motor vehicle.For conventional truck, clutch, speed changer, power transmission shaft, all be absolutely necessary, and these parts not only weight big, make the structure of vehicle more complicated, the while also existence need the problem of periodic maintenance and failure rate.Except that structure simply, the vehicle that adopts wheel hub motor to drive can obtain better space availability ratio, transmission efficiency has exceeded 6 times simultaneously.
Description of drawings
Fig. 1 is the dissection sketch map of the engine housing of the utility model;
Fig. 2 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe in detail:
Referring to Fig. 1 and Fig. 2; The utility model comprises casing 9; Rotor carriage 2, brake disc 3, stator 4, rotor 5, terminal pad 6, stator bracket 7 and body suspension support 8 are installed in casing 9; Power transmission shaft 11 is arranged on the casing 9 with fixture 12, and casing 9 is provided with a plurality of fixtures 12, is installed on the hub for vehicle wheel 1 through fixture 12.Stator bracket 7 is arranged on the body suspension support 8, and motor cover 10 also is installed on casing 9.
The utility model power transmission and brake apparatus all are incorporated in the wheel hub 1, and the mechanical part of motor vehicle has been simplified, and to obtain better space availability ratio, transmission efficiency has exceeded 6 times simultaneously.The utility model is an inner rotor motor, rotor 5 externally, stator 4 is in inside, inner rotor motor has adopted high speed internal rotor technology, it has been equipped with the decelerator of fixed drive ratio, for obtaining higher power density, rotating speed of motor can be up to 10000r/min.
