Abstract
The utility model discloses a composite-type integral wheel motor of an electric motor car, comprising an integral wheel, a left end cover and a right end cover, a stator, a stator coil winding, a magnetic steel sheet and a motor shaft. The left end cover and the right end cover are arranged at two sides of the integral wheel and connected to the motor shaft through bearings, and the integral wheel and any one of the left end cover and the right end cover form a whole wheel hub integrally arranged. The composite-type integral wheel motor has the advantages of favorable concentricity, uniform motor air gap, and the like.
Description
Technical field
The utility model relates to a kind of motor, specifically is meant a kind of electric motor car composite type one turbin generator that is applicable to electric vehicle.
Background technology
At present, electric vehicle motor on the market is (also to can be described as the hub rotor by left and right end cap, one wheel, normal be aluminium wheel or spoke wheel), parts formations such as stator, stator winding coil, motor shaft, wherein the one wheel tightens magnet steel, motor shaft passes stator, left and right end cap is loaded onto bearing, and left and right end cap is fastened on the one wheel by screw, and motor shaft is connected with end cap by bearing.The electric vehicle motor of this structure is in assembling process, because left and right end cap and one wheel are processing respectively, when the fastening end cap of screw is on the one wheel, inevitably caused the concentricity tolerance overproof problem of end cap to the one wheel, at this moment overproof just is reacted directly into the decentraction problem of motor stator and magnet steel, thereby produce the uneven situation of air gap, influence the sky of motor, the unit for electrical property parameters of load, also can occur " sweeping boring " situation when serious.In addition, it is poor that this existing electric vehicle motor is led while motor water resistance, the waterproof technology complexity.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and a kind of good concentricity, the uniform electric motor car composite type of motor gas-gap one turbin generator are provided.
For achieving the above object, the technical solution of the utility model is to include one wheel, left and right sides end cap, stator, stator coil winding, magnetic links, motor shaft, described left and right sides end cap is arranged at the both sides of one wheel, and this left and right sides end cap is connected with motor shaft by bearing, the whole wheel hub of the integrated setting of arbitrary end cap in described one wheel and the left and right sides end cap.By this setting, adopt the design of whole wheel hub, processing and assembling process in all location dimensions again clamping can process at one time, guarantee concentricity, solved problems such as air gap that the conventional electric vehicle motor occurs the overproof problem of concentricity tolerance of one wheel because of end cap is inhomogeneous.
Further be provided with that to be described motor shaft have oil sealing with respect to the bearing arranged outside of the end cap of whole wheel hub and opposite side, and be provided with oiling groove between oil sealing and the bearing, be provided with lubricant grease in this oiling groove.By this setting, oil sealing plays waterproof action, in addition, is provided with oiling groove between oil sealing and bearing, and is provided with lubricant grease in oiling groove, not only strengthens water-proof function, and can also carry out sufficient lubrication to the bearing operation, protects its stable operation.
Further being provided with is the described magnet steel circle that also includes, and described magnetic links is pasted and fixed on the magnet steel circle, and this magnet steel circle presses to cooperate to be pressed into and is fixed in the whole wheel hub.This setting, magnetic links is sticked on the magnet steel circle, again the magnet steel circle is pressed into whole wheel hub, this structure reduces the technology difficulty that Lun Grains makes, if motor wheel hub distortion after sale simultaneously, traditional motor motor need magnet steel together with changeing the Grains integral replacing, this structure of the utility model only need be changed the whole hub that changes, magnet steel circle and magnet steel still can utilize, and greatly reduce the after-sales service cost.
Further be provided be described with respect to arbitrary end cap that whole wheel hub comprised another end cap and whole wheel hub between be provided with the O RunddichtringO.This is provided with and has guaranteed that another end cap seal is fixed on the whole wheel hub.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
Description of drawings
Fig. 1 the utility model embodiment structural representation;
Embodiment
Embodiment of the present utility model as shown in Figure 1, include one wheel 1, left and right sides end cap, stator 3, stator coil winding 4, magnetic links 5, motor shaft 6, described left and right sides end cap 2 is arranged at the both sides of one wheel 1, and this left and right sides end cap 2 is connected with motor shaft 6 by bearing 7 respectively, the whole wheel hub 8 of the arbitrary end cap 21 integrated settings in described one wheel 1 and the left and right sides end cap 2, the utility model adopts the design of whole wheel hub 8, processing and assembling process in all location dimensions again clamping can process at one time, guarantee concentricity, solved problems such as air gap that the conventional electric vehicle motor occurs the overproof problem of concentricity tolerance of one wheel because of end cap is inhomogeneous.In addition; the described motor shaft 6 of present embodiment has oil sealing 9 with respect to bearing 7 arranged outside of the end cap 22 of whole wheel hub 8 and opposite side; and be provided with oiling groove 10 between oil sealing and the bearing, be provided with lubricant grease in this oiling groove 10, oil sealing 9 plays waterproof action; in addition; between oil sealing 9 and bearing 7, be provided with oiling groove 10, and in oiling groove 10, be provided with lubricant grease, not only strengthen its water-proof function; and can also carry out sufficient lubrication to bearing 7 operations, protect its stable operation.
Present embodiment also includes magnet steel circle 11, described magnetic links 5 is pasted and fixed on the magnet steel circle 11, and this magnet steel circle 11 presses to cooperate to be pressed into and is fixed on one opinion 1 positions in the whole wheel hub 8, this mode of present embodiment reduces the technology difficulty that Lun Grains makes, if motor wheel hub distortion after sale simultaneously, traditional motor motor needs magnet steel together with changeing the Grains integral replacing, this structure of the utility model only need be changed the whole hub 3 that changes, magnet steel circle 11 and magnetic links 5 still can utilize, and greatly reduce the after-sales service cost.
Further being provided with is to be provided with 0 RunddichtringO 12 between another end cap 22 and the whole wheel hub 8 of the described arbitrary end cap 21 that is comprised with respect to whole wheel hub 8, has guaranteed that another end cap 22 seals to be fixed on the whole wheel hub 8.
