Can draw from the concept of above-mentioned interference fit, the volume being exactly power brick 3 in fact for interference fit between power brick 3 and axocoel 6 is greater than the space in axocoel 6, need to use certain method to be placed in axocoel 6 by power brick 3, so just can prevent power brick 3 from coming off in axocoel 6 by actv..
In the present embodiment, the mode that power brick 3 is inserted in axocoel 6 is, is wrapped up outside power brick 3 by relatively soft material, power brick 3 is squeezed in axocoel 6 by the outer material extruding power brick 3.
Be preferred embodiment that the arranged outside of described hub body 2 has tire 1.
Tire 1 is the annular arrangement elastic rubber product rolled at various vehicle or the ground connection of mechanically assembling.Usually be arranged in alloy rim, can vehicle body be supported, buffering foreign impacts, realize with the contact on road surface and ensure the rideability of vehicle.Tire 1 is everlasting under complicated and exacting terms and is used, and it subjects various distortion, load, power and high/low temperature effect in motion, therefore must have higher load-carrying properties, tractive property, cushion characteristic.
Meanwhile, also require to possess high-wearing feature and flexible resistance, and low rolling resistance and heat generation.The half that the world consumes rubber mass is produced for tire 1, and visible tire 1 consumes the ability of rubber.
In the present embodiment, at the arranged outside tire 1 of hub body 2, by tire 1, damping is carried out to the traveling of electronlmobil.
Be preferred embodiment that described drive motor 4 is torque motor.
Torque motor is a kind of specific type of electric machine with soft mechanical characteristic and wide speed regulating range, and it is a kind of platypelloid type multipole permanent magnet direct current motor.Its armature has more groove number, number of segment and series conductor number, to reduce torque pulsation and speed ripple.The feature such as there is slow speed of revolution, high pulling torque, overload capacity is strong, response is fast, characteristics linearity degree is good, torque fluctuations is little.The axle of torque motor is not with constant power output power but with constant moment of force outputting power.Torque motor has direct current torque motor and alternating current torque motor two kinds.
Wherein, have employed direct current torque motor in the utility model, the self-induction reactance of direct current torque motor is very little, so responsibility is fine; Its output torque is directly proportional to received current, has nothing to do with the speed of rotor and position; It without gear reduction, so can produce very high moment to inertia ratio on the axle of load, and can eliminate the systematic error produced owing to using reducing gear close to being directly connected low cruise with load under locked rotor condition.
The novel hub electric machine structure that the utility model provides, is provided with power brick 3 in the space between hub body 2 and drive motor 4.After the electrokinetic cell bag 3 of motorized motions is placed, the space in car cabin can be saved, and then make the utilized space of vehicle body become larger; Power brick 3 is arranged on outside car cabin, if et out of order, particularly battery explosion occurs, the injury to the driver and conductor in car cabin can be reduced, substantially increase the safety of electronlmobil.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
