Abstract
The invention relates to a universal hub motor suitable for vehicles of various models, including rail cars and various electric cars. The universal hub motor can be directly insert in the axles of the vehicles of various models; the axle is taken as the shaft of the motor, and the shaft of the motor is integrated with the axle, so that the electric cars can be manufactured and assembled, and repaired, mounted and demounted very conveniently.
Description
Technical field
The present invention relates to vehicle technology field, particularly relate to the Universal hub motor that a kind of electric automobile is special.
Background technology
Current wheel hub motor is all the solid axle motor that wheel shaft can not be pulled out from motor, because the stator of motor is directly installed on wheel shaft, be positioned at stator peripheral and the double wheel hub rotor doing motor housing is also rotated by the bearing of stator both sides to be packed on wheel shaft, make wheel shaft become the requisite installing base frame of wheel hub motor.The wheel hub motor of this structure cannot be pulled down from entirety wheel shaft freely, because once pull down, the stators and rotators of wheel hub motor will lose installing base frame and mutual dislocation is fallen apart, not integral.Electric automobile adopts the wheel hub motor of this spline structure just to make the handling of driving wheel very inconvenient, is not easy to produce in enormous quantities and ordinary maintenance; In addition, all wires of this wheel hub motor are all that to pass motor from the through wires hole in wheel shaft external, are exposedly connected with controller line connector outside, not only many artificial operations connected together, also easily meet water short circuit simultaneously and reduce the reliability of electrical connection.
Summary of the invention
The object of this invention is to provide a kind of can on electric automobile wheel shaft the Universal hub motor of bulk handling.
For realizing object, the present invention adopts following technical scheme: Universal hub motor, and comprise stator and be positioned at the double wheel hub rotor doing motor housing of stator peripheral, automobile tire is arranged on wheel hub rotor; Also comprise hollow bushing, described stator is installed on the outer wall in hollow bushing stage casing, the outer wall at hollow bushing two ends also respectively fills a bearing near stator both sides, wheel hub rotor is wrapped in stator and is arranged on the bearing at hollow bushing two ends, make rotor and stator on hollow bushing, be assembled into an entirety, this entirety is inserted on axletree by hollow bushing; The first elasticity electric connection terminal that hollow bushing inwall is provided with axial through keyway and is electrically connected with coil of stator of motor.
Accompanying drawing explanation
Fig. 1 is the structural representation of Universal hub motor of the present invention.
Embodiment
Universal hub motor shown in Fig. 1, comprise hollow bushing 5, hollow bushing outer wall is installed with stator, stator pack vinculum circle 3 and the stator support 4 be arranged on hollow bushing, the hollow bushing outer wall of stator both sides is also equipped with bearing 8 respectively, be positioned at stator peripheral and the double wheel hub rotor 1 doing motor housing is arranged on bearing 8, the inwall of wheel hub rotor have magnet steel 2.Hollow bushing inwall is provided with axially through keyway 6, the stage casing of hollow bushing inwall is provided with deep gouge in the position that keyway is relative, be provided with in deep gouge side be communicated with this deep gouge and the wire via hole of radial penetration hollow sleeve tube wall, elasticity electric connection terminal 7 is embedded with in deep gouge, motor coil lead-out wire 9 is electrically connected with elasticity electric connection terminal 7 through wire via hole, elasticity electric connection terminal 7 is elasticity pressure contravention, and its elasticity pressure is touched position and protruded from hollow bushing inwall.
Above-mentioned Universal hub motor and axletree freely can either plug together and can be separated from each other, and while driving wheel is installed on axletree, the line of wheel hub motor and controller also can be connected simultaneously automatically, and driving wheel is is freely loaded and unloaded on axletree.
Claims (1)
1.
