The present invention researches and develops for solving the problem, and its object is to provide a kind of wheel hub motor, uses general wheel, configures disc-type outer rotor motor, disk braking system and simple cooling mechanism efficiently in inside wheel space.
technical scheme
For reaching above-mentioned purpose, the feature of wheel hub motor of the present invention is: adopt compact outer rotor disc type motor, its stator is positioned at inside, connect firmly not with hub rotation with hub bracket, rotor is in outside, jointly rotate with wheel hub, plate disc brake is arranged in stator interior space, and rotor exterior arranges radiating fin.
Further, permanent magnet is arranged at equal intervals in inner rotor face relative stator direction, and permanent magnet magnetic field direction is along rotor radial, and adjacent permanent magnet magnetic direction is contrary;
Further, outside stator, the excitation coil of equal number is circumferentially arranged in relative rotor direction at equal intervals, and excitation coil is iron-less core coil, and the magnetic direction produced during each coil electricity is contrary with corresponding permanent magnet magnetic field direction;
Further, for avoiding foreign matter to enter motor internal, rotating seal ring is established between the stator and the rotor.
Further, for solving motor radiating problem, there is radiating fin in relativeatoeterahub direction, rotor outer ring, by air flowing, the heat that motor runs being dissipated when rotor drives vehicle wheel rotation.
Further, arrange the brake disc rotated with wheel hub in stator interior space, brake caliper assemblies is connected firmly by support and hub support frame and stator, does not rotate with wheel hub.During braking, the brake plate in brake clamp and brake disc friction, reach the effect of braking.
Another object of the present invention is to improve a kind of electric wheel, comprise wheel hub and be installed on the tire on described wheel hub, also comprise wheel hub motor as above, wheel hub is fixed on the wheel hub adapter flange of described wheel hub motor.
Electric wheel of the present invention uses above-mentioned wheel hub motor, use general wheel, in inside wheel space, configure disc-type outer rotor motor, disk braking system and simple cooling mechanism efficiently, can be vehicle and powerful, spaces compact, heat radiation is good, drive efficiency is high drive system are provided.
technique effect
According to wheel hub motor cooling system of the present invention, there is following effect: suspension frame structure is without the need to changing, drive motor compact conformation, effectively wheel hub motor is cooled by the particular design of rotor, plate disc brake is held in wheel hub inner space, to brake system without the need to transforming, standard wheel can be used, therefore improve the comformability of wheel hub motor.
one. accompanying drawing illustrates:
A kind of wheel hub motor plane TV structure schematic diagram that Fig. 1 provides for the embodiment of the present invention one;
Fig. 2 is the schematic diagram of the motor stator of Fig. 1 and the excitation coil of rotor arrangements and permanent magnet;
two. detailed description of the invention:
Should be understood that, pointing out in embodiments of the invention, the mode by means of only example provides detailed description and object lesson, and the various change in the present invention's spirit and right and amendment are not formed differentiation of the present invention.
In the simple embodiment of such as Fig. 1, hub support frame 13 is connected with wheel suspension, its hub spindle 14 is the bases supporting other associated components. hub spindle 14 is connected to successively brake disc 11, motor stator 6, rotor 3, wheel hub adapter flange 5, wheel hub 4 is fixed on flange 5 by wheel hub screw (not providing in figure).Brake disc, rotor 3 and flange 5 are cemented on sleeve 15, supported, freely can rotate around hub spindle 14 by bearing (not providing in figure).Stator 6 is supported on sleeve 15 by another bearing (not providing), and support 12 makes stator 6 fix with bracing frame 13, does not relatively rotate.Support 12 is also fixedly connected with brake caliper assemblies 10 simultaneously.
Rotor 3 circumferentially arranges permanent magnet 7 at equal intervals in inner face relative stator direction.The magnetic direction of permanent magnet 7 is along rotor radial, and adjacent permanent magnet magnetic direction is contrary.The relative rotor direction, outside of stator 6, circumferentially arranges the excitation coil 9 of equal amount at equal intervals.The single copper wire winding of excitation coil 9, its axis is radial along stator, and the magnetic direction that during energising, it produces is contrary with permanent magnet 7.Like this, electromagnetic force drive rotor rotates after powered up, thus drives vehicle wheel rotation.
