Abstract
The utility model relates to a two-speed motor, which is mainly characterized in that the output end of a motor rotor is provided with a control electromagnet, a pair of overrunning couplers, a planetary mechanism and a power output tray. A pair of overrunning couplers can be respectively meshed with a solar wheel and the power output tray in the planetary mechanism, and an overrunning coupler onthe wheel frame of a planet wheel is meshed with outer ratchets on the power output tray. The power output tray can realize low or high gear rotation by manipulating the control electromagnet. For anelectric bike which is configured by the two-speed motor, a biker can easily achieve speed-changing or climbing riding according to road conditions. The ability to continuation riding of a storage battery is prolonged, and the service life of the storage battery is prolonged.
Description
Technical field
The utility model relates to motor, is a kind of two-speed motor of gear shift speed change.
Background technology
Motor of the prior art mainly is made up of motor housing, stator and rotor, and its operating state both can just have been changeed also and can have been reversed, and rotating speed is generally immutable.When being assembled into electric bicycle with existing motor, because of it can't realize the climbing requirement of the many multiplications of moment of torsion, in case run into the ramp or can't get on substantially in the hill path, the starting difficulty, therefore make troubles to the user, this just existing electric bicycle is difficult at road the city of fluctuating and the main cause that promote in the small towns are arranged.
Summary of the invention
The purpose of this utility model is, a kind of two-speed motor is provided, and enables to realize shifted, is assembled into such as behind the electric bicycle to reach, and satisfies climbing at a slow speed, the requirement that level road runs at a constant speed.
Realize the utility model of above-mentioned purpose, have general motor total motor housing, stator and rotor.Characteristics of the present utility model are that the rotor output is provided with a control electromagnet, a pair of freewheel clutch, a planet mechanism and a power output panel on fixed main shaft.Said a pair of freewheel clutch is connected on the control electromagnet core; The handle ratchet wheel of sun gear can be meshed with said wherein freewheel clutch in the planetary mechanism, and the external gear of sun gear is meshed with planetary gear; On the inner periphery of planetary gear wheel carrier, be provided with a freewheel clutch; Respectively be provided with a circle ratchet on the inside and outside circumference of power output panel, the outer ratchet on this excircle can be meshed with the freewheel clutch on the planetary gear wheel carrier, and the interior ratchet on the inner periphery can be meshed with the another freewheel clutch on the electromagnet core.The utility model of structure like this, make wherein freewheel clutch and (another freewheel clutch disengage from) after the interior ratchet of sun gear is meshed on it when controlling electromagnet, the planetary mechanism that is meshed with the external gear of sun gear then is meshed with outer ratchet on the power output dish excircle by the freewheel clutch on its wheel carrier, at this moment, power output panel rotates with low or first gear.When controlling electromagnet another freewheel clutch interior ratchet direct and on the power output panel is meshed (the interior ratchet of sun gear and last freewheel clutch are the engagement disengaged position), at this moment, power output panel then top gear rotates.
Planetary gear in the utility model can be provided with three, four, five or six, need dispose three at least and just can guarantee stability.
The utility model as mentioned above, because of in motor, being provided with freewheel clutch and planetary mechanism by the gear shift magnet control, therefore can realize shifted, the electric bicycle that is configured to the utility model, the driver can travel according to road conditions realization speed change or climbing easily, effectively utilize storage battery, prolong the ability that continues of storage battery, improve the life-span of storage battery.
Description of drawings
Fig. 1 is the cross-sectional schematic of an embodiment of the utility model.
Embodiment
Preferable embodiment of the utility model is a kind of in order to be assembled into the two-speed motor of electric bicycle as shown in the figure.
