Abstract
The utility model relates to an outgoing line structure for a hub motor shaft of an electric vehicle. The outgoing line structure comprises a hub, an end cover, a disc braking cover, a stator, a rotor steel magnet, a motor shaft and an outgoing line, wherein the end cover and the disc braking cover are respectively and fixedly arranged at two ends of the hub; the rotor steel magnet and the stator are installed in the hub and oppositely arranged; the motor shaft penetrates through the hub, and the stator is fixed on the motor shaft; and a plurality of scattered threading holes are evenly distributed on the motor shaft, and the outgoing line penetrates through the scattered threading holes to be connected with the stator. By arranging the plurality of scattered threading holes, the section area of the outgoing line is larger than that of an integrated structure, and large current resisting capability is strong, safety and stability of a motor in working is effectively improved, and the outgoing line structure is suitable for hub motors large in power.
Description
Technical field
The utility model relates to a kind of structural improvement of wheel hub electric motor of electric vehicle axle, is specifically related to a kind of wheel hub electric motor of electric vehicle axle lead-out wire structure, belongs to the vehicle technology field.
Background technology
The wheel hub electric motor of electric vehicle axle lead-out wire of prior art is generally centralized configuration, and a through wires hole promptly only is set on motor shaft, and all lead-out wires all get in the wheel hub through this through wires hole.And since this through wires hole tiltedly punch from the motor shaft center, thereby influence the intensity of this motor shaft easily, and the sectional area of lead-out wire can receive great limitation, influences the power of motor.
Therefore, for solving the problems of the technologies described above, necessary a kind of structure improved wheel hub electric motor of electric vehicle axle lead-out wire structure that has is provided, to overcome said defective of the prior art.
The utility model content
For addressing the above problem, the purpose of the utility model is to provide a kind of distributing wheel hub electric motor of electric vehicle axle lead-out wire structure.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of wheel hub electric motor of electric vehicle axle lead-out wire structure, and it comprises wheel hub, end cap, disc brake lid, stator, rotor magnetic steel, motor shaft and lead-out wire; Wherein, said end cap and disc brake lid is immobilizated in the two ends of wheel hub respectively; Said rotor magnetic steel and stator are installed in the said wheel hub, and this rotor magnetic steel and stator are oppositely arranged; Said motor shaft passes said wheel hub, is fixed with said stator on it; On said motor shaft, be evenly equipped with some distributing through wires holes, said lead-out wire passes said distributing through wires hole and is connected with stator.
The wheel hub electric motor of electric vehicle axle lead-out wire structure of the utility model further is set to: adopt flat key to fix between said motor shaft and the stator.
The wheel hub electric motor of electric vehicle axle lead-out wire structure of the utility model also is set to: pass through bearings respectively between said motor shaft and end cap, the disc brake lid.
Compared with prior art; The utlity model has following beneficial effect: the wheel hub electric motor of electric vehicle axle lead-out wire structure of the utility model is through being provided with some distributing through wires holes; Thereby make big, the anti-big current capacity of sectional area of sectional area ratio centralized configuration of lead-out wire strong; Fail safe when effectively having improved machine operation and stability are more suitable for being used for the use of high-power wheel hub motor.
Description of drawings
Fig. 1 is the structural representation of the wheel hub electric motor of electric vehicle axle lead-out wire structure of the utility model.
Fig. 2 is along the profile of A-A among Fig. 1.
Embodiment
See also Figure of description 1 with shown in the accompanying drawing 2, the utility model is a kind of wheel hub electric motor of electric vehicle axle lead-out wire structure, and it is formed by a few part assemblings such as wheel hub 1, end cap 2, disc brake lid 3, stator 4, rotor magnetic steel 5, motor shaft 6 and lead-out wires 7.
Wherein, said end cap 2 and disc brake lid 3 are immobilizated in the two ends of wheel hub 1 respectively.Said rotor magnetic steel 5 and stator 4 are installed in the said wheel hub 1, and this rotor magnetic steel 5 is oppositely arranged with stator 4.
Said motor shaft 6 passes said wheel hub 1, is fixed with said stator 4 on it, specifically, adopts flat key to fix between motor shaft 6 and the stator 4.
The greatest improvement part of the wheel hub electric motor of electric vehicle axle lead-out wire structure of the utility model is: on said motor shaft 6, be evenly equipped with some distributing through wires holes 61, said lead-out wire 7 passes said distributing through wires hole 61 and is connected with stator 4.
Further, support through bearing 8 respectively between said motor shaft 6 and end cap 2, the disc brake lid 3.
The wheel hub electric motor of electric vehicle axle lead-out wire structure of the utility model is through being provided with some distributing through wires holes 61; Thereby make big, the anti-big current capacity of sectional area of sectional area ratio centralized configuration of lead-out wire 7 strong; Fail safe when effectively having improved machine operation and stability are more suitable for being used for the use of high-power wheel hub motor.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection range of this creation.
