Description
Technical field:
The utility model relates to a kind of modified model motor of electric bicycle technical field, and the shank formula that is specifically related to a kind of electric bicycle slides motor.
Background technology:
The motor of electric bicycle comprises shell, stationary part and rotor portion.Wherein stationary part is positioned at the center; Be provided with axletree, axletree both sides and workshop are fixed, and stationary part comprises stator core and stator coil; Be connected with Hall plate on the stator coil, the power line of stator coil and the control line of Hall plate are all along drawing in the axletree one side inner chamber; Rotor portion is positioned at going out of stationary part, adopts permanent magnet usually, and is fixed together with wheel hub.So all there is a drawback in existing electric motor car, under the situation of outage, still there is magnetic force (rotor portion of permanent magnet is to the attraction of stator core) between because of stationary part and rotor exactly, so just influenced and slided effect normally.A very short end distance is freely gone from stopping in car body outage back.The version of this motor also drives to manpower and has brought very burden, effort and gait of march is slow.
The utility model content:
The utility model is not enough with existence to the present situation of existing electric bicycle, and the shank formula that proposes a kind of electric bicycle slides motor.
The technical scheme that the utility model adopted: a kind of shank formula of electric bicycle slides motor; Comprise motor housing, rotor portion and stationary part, wherein motor housing comprises the and arranged on left and right sides supports end cap; This supported on both sides end cap and wheel hub are fixed together; Stationary part comprises stator core and stator coil, and stator core is fixed on the axletree through supporting pair, and rotor portion comprises a semi-enclosed support cover; The lid support cover comprises the outer cover of a discoid side and an annular, and each magnet of rotor portion is uniformly distributed with respectively on the inner surface that is fixed in this annular outer cover; In stationary part suit and the said support cover; Bearing Installation is passed through on axletree in the center of the discoid side of said support cover; The center of the and arranged on left and right sides supports end cap of said housing all through Bearing Installation on axletree; And be provided with shank shape clutch between the discoid side of said support cover and the housing one side supports end cap.
Said shank shape clutch comprises inner rotary member that is fixed on center, discoid side and the external rotary member that is fixed on the supports end cap center; This inner rotary member and external rotary member coupling interlock; Be distributed with shank shape elastic chuck on the outer rim of inner rotary member; The inner edge of external rotary member is provided with the zigzag draw-in groove of annular, and this shank shape elastic chuck springs in each zigzag draw-in groove automatically.
Distributed and arranged has the arc groove that is uniformly distributed with on the said inner rotary member outer rim; One side of each arc groove is provided with the retaining edge; Retaining edge and groove one end form the circular shaft nest; One end of shank shape dop is arranged to the spindle nose with this nest coupling, between the inboard of shank shape dop is bottom arc groove, is provided with elastic card or jump ring.
Bearing is separately positioned on the center of said inner rotary member and external rotary member.
The good effect of the utility model: 1, the utility model separates rotor portion through a semi-enclosed support cover with motor housing, and is that this support cover and motor housing keep the one-way clutch relation through shank shape clutch.Thereby to the coil of stator of motor normal power-up time, the rotation of rotor driven support cover, the rotation of support cover bronze drum shank shape clutch drive motors shell, and then be the wheel rotation.When motor is cut off the power supply, be in disengaged position between support cover and the motor housing, the car body operation does not receive the constraint of motor stator and rotor, and because of the operation effect of inertia of car body self, car body can slide very long distance.When manpower drove (not having), car body can freely go under external force, does not receive the constraint of motor stator and rotor, and was light laborsaving.
2, according to experiment, the coasting distance in the straight road running is more than 200 meters, is far longer than the coasting distance of existing electric bicycle at present, thereby saves energy resource better improves storage battery useful life, increases the distance travelled of electric bicycle.With certain abnormal shape electric bicycle is example, does not slide 70 kilometers, can reach 70 kilometers+10 kilometers mileage and slide.
3, the utility model is improved simple in structure, practicality, environmental protection.Be beneficial to very much promotion and implementation.
