Description
Technical field
The utility model relates to the integrated mid-motor of a kind of electric bicycle internal speed-changing motor wheel disc; Be installed on the five-way of electric bicycle vehicle frame middle part; Can driven by power, manpower driving, manpower and electric power driven in common or drive respectively, do not influence mutually, energy consumption is little in the motion; The transmission of power is reliable and stable, and climbing capacity is strong.
Technical background
At present, the hub-type motor is still the crucial matching component of drive system of electric motor vehicle.Though brushless electric machine major part has replaced brush motor, all in all production technology falls behind, and almost all still is manual coiling so far.The high gear reducing motor has the advantage that moment of torsion is big, climbing capacity is strong, but because design and manufacturing technology does not reach a standard as yet fully, and quality problems happen occasionally, still fails to become main product and replace the low speed brushless hub electric motor.In addition, the reliability of controller (repair rate) still only can be controlled at about 1-3% preferably at present, and the whole quality of driving control system still is in than low water-mark.
Shortcoming and deficiency that existing small-sized electric car wheel hub motor product exists are: low speed wheel hub motor climbing capacity is poor, and efficient reduces under the high pulling torque; Thereby motor diameter and volume do bigger and bigger, accomplishes 222mm, 266mm gradually from 142mm, 153mm, 205mm, because the metal consumptive material is many, motor is heavy, causes power and energy density very low, does not meet the requirements of the times of conservation-minded society and lightness.In addition, because the motor magnetic air gap is little, motor housing directly bears the most of load of car load, and easy generation rotor permanent magnetism sheet and stator core scratch, magnetic sheet come off under heavy duty, and motor can't rotate so that the catastrophe failure that can't ride.
The problem that has the gear hub motor to exist at present at a high speed mainly is: Gear Transmission Design, manufacturing technology are still immature; Product ubiquity efficient is not high, noise is big, the phenomenon of easy tooth-breaking, pawl; And most of product is the semiaxis structure; Bearing capacity is poor, and the electric motor car rear axle need bear about 70% (promptly axle is heavy) up to total load of whole load-carryings, so be prone to cause the generation of accident.
At present, the still later wheel hub motor type of drive of the motor-driven technology of small-sized electric car is main, and it is simple in structure, and low cost of manufacture is still the main product in electric motor car market now.Because the rear-wheel hub motor has occupied back shaft position; Thereby can not image height shelves bicycle that kind be installed by speed gear mounted in rear hub or outer speed changer; Car load can only depend on power performance---torque, the rotary speed property of motor fully for the adaptive capacity of different road conditions; Low-speed big facing the wind or the ability of riding such as climbing will be very limited, can't expand.
The front-wheel hub motor drive mode only accounts for very small scale all the time, and there is the wretched insufficiency that influences people's control stability problem of riding in this mode.The front and back wheel product of type of drive simultaneously only accounts for few part, is detected in some external product at present, and its power is front and back two motor sums, thereby actuating force is powerful, and it is strong to adapt to the complex road surface ability, and acceleration performance is good, and climbing capacity is big.But because power consumption is excessive, and battery power is limited, and the continual mileage that once charges is short, and the front and back wheel motor need coordinate control, only is suitable for special purpose and uses.
