In being mounted with permanent magnet on rotor 2, the magnetic pole of permanent magnet is fixed, and according to the magnetic pole principle that identical charges repel each other, rotor exists
The lower rotation of rotating excitation field effect that stator produces, rotor are fixed on drive end bearing bracket, drive end bearing bracket be connected by screw with wheel hub so that
Band electrical automobile advance
The wheel hub motor of the present embodiment is similar to conventional boss motor, is bisalient-pole permanent-magnet synchronous machine.Unlike,
Various forms of heat pipes and/or fin are disposed with hub motor shell, rotor and stator, using the excellent heat pipe of heat conduction and are dissipated
The good fin of heat takes away the main heat of wheel hub motor, carries out forced-convection heat transfer with air, makes wheel hub motor thermal diffusivity
It can be improved, maintain motor normal working temperature.
In the process of moving, stator 4, rotor 2 can all produce substantial amounts of heat to automobile, and the heat of stator 4 passes through stator heat
Pipe 7-3 is exported, and the heat absorbing end of stator heat pipe 7-3 absorbs the heat that stator produces, and working solution vaporization transfers heat to radiating end,
Radiating end heat pipe is welded with stator radiating fin 8-3, increases heat exchange area, by exchanging heat with forcing ambient air convection current.
The heat that rotor 2 produces is delivered to wheel hub motor drive end bearing bracket 1, while wheel hub motor front end cover 1 by rotor heat pipe 7-2 from rotor
It is equipped with drive end bearing bracket heat pipe 7-1 and the first drive end bearing bracket radiating fin 8-1;Carried out in the first drive end bearing bracket radiating fin 8-1 and air
Forced-convection heat transfer.Therefore, realized in terms of stator, rotor, electric motor end cap three by heat pipe and fin by the heat of motor
It is rapid to be dispersed into the external world, wheel hub motor inside and the suitable temperature of shell are maintained, to ensure the normal work of motor.
Embodiment 2
Such as Fig. 3, shown in Fig. 4, a kind of constructional device for strengthening wheel hub motor heat dissipation performance, mainly includes wheel hub motor front end
Lid 1, rotor 2, bearing 3, stator 4, dead axle 5, wheel hub motor rear end cap 6, heat pipe and radiating fin.The wheel hub motor and tradition
Wheel hub motor is similar, is bisalient-pole permanent-magnet synchronous machine.The difference is that being disposed with not on hub motor shell, rotor and stator
With the heat pipe or fin of form, using the fin of the good heat pipe of heat conduction and excellent heat radiation performance by the main heat band of wheel hub motor
Walk, carry out forced-convection heat transfer with air, improved wheel hub motor heat dissipation performance, maintain motor normal working temperature.
As different from Example 1, the present embodiment dissipates the present embodiment 2 in wheel hub motor drive end bearing bracket 1 equipped with the second drive end bearing bracket
Hot fin 8-2, without the drive end bearing bracket heat pipe 7-1 and the first drive end bearing bracket radiating fin 8-1 of embodiment 1.As shown in Figure 7, Figure 8,
Second drive end bearing bracket radiating fin 8-2 is cellular fin;Cellular fin is mutual for regular hexagon hollow-core construction by multiple sections
Connection composition;The height of cellular fin is 8-10mm, and every block of plate for forming regular hexagon is equipped with one or more aperture.
The each heat exchange unit of the present embodiment is regular hexagon, and multiple heat exchange units are covered with whole drive end bearing bracket end face uniform sequentially;Honeycomb
Shape fin is designed according to bionics principle, and this design can allow heat dissipation area to maximize, while can ensure that fin has
Enough intensity, to adapt to different vehicle conditions.Be provided with aperture in the fin plate face of each heat exchange unit, allow the flow to by,
Increase disturbance, enhanced heat exchange.
As shown in Figure 9, Figure 10, the heat produced on rotor 2 is conducted by rotor heat pipe 7-2, and rotor heat pipe 7-2 inhales
The heat that rotor 2 produces is received, working solution heat absorption vaporization, carries out condensation heat release near outer surface of motor in heat pipe, is dispersed into outer
The heat on surface is radiated by the cellular second drive end bearing bracket radiating fin 8-2 of wheel hub motor drive end bearing bracket 1 again, and automobile is whole
During justification is sailed, the second drive end bearing bracket radiating fin 8-2 has larger area density, and heat dissipation area is very big, and heat is outside motor
Shell is uniformly transferred on each surface of honeycomb fin, and due to the effect of negative pressure and centrifugal force, the air-flow of high-speed motion is from honeycomb
Heat emission hole on face flows through, and increases flow perturbation, enhanced heat exchange performance, so as to fulfill forced-convection heat transfer by hub motor shell
The heat Quick diffusing of transmission is gone out, and wheel hub motor inside and the suitable temperature of shell is maintained, to ensure the normal work of motor.
