Abstract
The invention discloses an air cooling heat dissipation mechanism for a wheel hub motor of an electromobile. The air cooling heat dissipation mechanism comprises a wheel hub motor outer shell and a motor winding, and at least two vanes which protrude outwards are distributed on the circumference of the outer surface of one side of the wheel hub motor outer shell in an equidistant mode. Heat generated in the operation process of the wheel hub motor can be quickly scattered by the mechanism, the defects that operation can not be normally conducted due to too high temperatures caused by overload work such as increasing of the power of the wheel hub motor and increasing of torque are overcome, and the safety in the traveling process of the electromobile is guaranteed.
Description
Technical field
The present invention relates to electric automobile equipment cooling mechanism, particularly a kind of hub motor for electric automobile wind-cooling heat dissipating mechanism.
Background technology
Hub motor for electric automobile is a kind of hub unit that motor, drive system and braking system are merged.In recent years, along with the rise of electric automobile, wheel hub motor has more and more caused people's attention.Electric automobile employing wheel hub motor is compared with centralized driving has following several respects advantage: (1) dynamic Control changes by hard connection the pattern that is flexible coupling into, by electric line control technology, realize each Electric Motor Wheel from zero to the infinitely variable speeds of maximal rate and the differential requirement each Electric Motor Wheel, omit the required drive system of centralized driving electric automobile, made drive system and complete vehicle structure succinctly, effectively utilize that space is large, transmission efficiency is high.(2) actuating force of each Electric Motor Wheel is directly independent controlled, makes its dynamics Controlling more flexible, convenient, can reasonably control the actuating force of each Electric Motor Wheel, improves the rideability under severe pavement conditions.(3) easily realize electric braking, Electro-mechanical brake and the braking energy feedback of each Electric Motor Wheel, energy savings.(4) simplify Undercarriage structure.(5) realize the Vehicular turn high performance that travels, effectively reduce turning radius, increase and turn to nimble property.From the feature of current development trend and various Driving technique, wheel hub motor is the final drive form that is electric automobile,
Wheel hub motor caloric value in the course of the work can increase along with the increase of wheel hub motor power and moment of torsion, but machine operation has certain temperature limiting, surpassing this limiting motor efficiency will reduce greatly, even cause motor to damage, in order normally to work at the temperature that wheel hub motor can be allowed at motor, wheel hub motor cooling mechanism must be set.
Summary of the invention
For Shortcomings in prior art, the invention provides a kind of for hub motor for electric automobile wind-cooling heat dissipating mechanism, this mechanism can the generation in service of rapid dispersion wheel hub motor heat, overcome wheel hub motor because of the shortcoming that the overworks such as power increasing, moment of torsion increase cause its excess Temperature normally to move, guaranteed electric automobile fail safe in the process of moving.
In order to solve problems of the prior art, the present invention adopts following technical scheme to implement:
For a hub motor for electric automobile wind-cooling heat dissipating mechanism, comprise hub motor shell, motor winding, on described hub motor shell one side external surface circumference, be equidistantly distributed with the blade of at least 2 above outwardly convexs.
Described wheel between hub shell and described motor winding is provided with heat conductive pad.
Described blade is arc.
The angle of described blade air outlet is less than 90 degree.
Distance between every described blade is 20mm～80mm.
The thickness of described blade is 3mm～5mm.
The height of described blade is 3mm～5mm.
Beneficial effect of the present invention: the first, the present invention, by arc fin is set on automotive hub shell, not only can increase the area of dissipation of wheel hub motor, but also can produce heat by rapid dispersion wheel hub motor.The second, the present invention increases thermal conductive silicon rubber cushion between hub motor shell and motor winding, makes the heat that arc fin can high efficiency derivation motor winding.The 3rd, arc heat radiating fin structure is simple, easy to process, can effectively guarantee that wheel hub motor can normally operation at the temperature of motor permission.

Embodiment
Below in conjunction with accompanying drawing, the present invention is done to describe in detail into a line:
As Fig. 1, as shown in Figure 2, the invention provides a kind of for hub motor for electric automobile wind-cooling heat dissipating mechanism, comprise hub motor shell 1, motor winding 2, the described blade 3 that is equidistantly distributed with at least 2 above outwardly convexs on hub shell 1 one side external surface circumference of taking turns.Consider that car wheel electromotor work is mainly to be undertaken by motor winding, so motor winding can produce a large amount of heats, if by described blade setting the position with respect to motor winding, can reach best radiating effect.Described blade 3 is arc.The angle of described blade air outlet is less than 90 degree.Distance between every described blade 3 is 20mm～80mm.The thickness of described blade 3 and quantity should be according to the heat dissipation capacity calculative determinations of wheel hub motor.It is the scope of 3mm～5mm that the present invention selects the thickness of blade.The height of described blade is 3mm～5mm.Described wheel between hub shell 1 and described motor winding 2 is provided with heat conductive pad 4.Described heat conductive pad 4 is made by silica gel material.
Operation principle of the present invention: the present invention designs the area of dissipation that increases on the one hand wheel hub motor; While utilizing rotation of wheel on the other hand, arc fin is with wheel High Rotation Speed, make the air of arc fin inner side along the gap between arc fin, be thrown out of wheel because wheel High Rotation Speed produces centrifugal force, because being thrown out of wheel, the air between arc fin makes to form negative pressure in arc fin simultaneously, cause Cryogenic air around to be supplemented into continuously by arc fin inner side, formed the circulation of arc fin surrounding air, take away the heat on arc fin, make motor radiating.
Above with reference to drawings and Examples, the present invention is schematically described, this description does not have restricted.Those of ordinary skill in the art will be understood that in actual applications, and in the present invention, the set-up mode of each parts some all may occur changes, and other staff also may make similar Design under its enlightenment.Only it is pointed out that otherwise depart from design aim of the present invention, all apparent changes and similar Design thereof, within being all included in protection scope of the present invention.
