Abstract
The invention discloses a device for precisely positioning a working gear of a motor. The device includes a gear cover, an output shaft and a final gear, wherein the final fear is fixedly connected with one end of the output shaft; the other end of the output shaft extends to the outer side of the gear cover; the output shaft can be matched with the gear cover in a rotating manner through bearings; a rotating speed inducing magnetic steel is mounted on the side surface of the top of the final gear; a Hall rotating speed sensor is fixedly mounted on the inner side of the gear cover, corresponding to the rotating speed inducing magnetic steel in position. The device for precisely positioning the working gear of the motor, provided by the invention can timely and precisely measure the actual running speed of an electrically-propelled bicycle, thereby precisely positioning the working gear of the motor, enables the motor to always work efficiently, and is strong in power and power-saving; and in addition, the device has the advantages of being low in manufacturing cost and convenient to mount.
Description
Technical field
The present invention relates to a kind of device, especially a kind of device of accurate positioning motor operation range.
Background technology
When the conventional electric bicycle installing shift motor uses, its machine operation gear obtains by measuring motor rotary speed, when electric bicycle is in descent run state, motor may stop operating, electric bicycle, by idle running under self existing speed, causes the operation range of motor incorrect.
Summary of the invention
The problem to be solved in the present invention is the deficiency overcome in background technology, a kind of device of accurate positioning motor operation range is provided, this device, by measuring the rotating speed of final output gear, accurate positioning motor operation range, make motor always work in high efficiency section, thus reach powerful power saving again, electric bicycle is ridden comfortable effect.
For solving the problem, the present invention takes following technical scheme:
The device of a kind of accurate positioning motor operation range of the present invention, comprise gear chamber cover, output shaft, final gear, described final gear is fixedly connected with one end of output shaft, the other end of output shaft reaches the outside of gear chamber cover, described output shaft forms rotatable cooperation by bearing and gear chamber cover, the end sides of described final gear is provided with Speed sensing magnet steel, and the inner side of the gear chamber cover corresponding with the position of Speed sensing magnet steel is installed with Hall Speed sensing device.
The Speed sensing magnet steel be arranged on final gear responded to by Hall Speed sensing device, obtain the true travel speed of electric bicycle, when the travel speed of electric bicycle is below a certain numerical value, automatically one grade of traveling is adjusted to, exceed then auto-changing to travel to second gear, when vehicle at full throttle travels, controller can go out instant load by automatic decision, automatically regulates and enters third gear traveling.If travel speed is in a certain value critical condition, then user can use one grade of control button to keep one grade of traveling.
The device of a kind of accurate positioning motor operation range of the present invention, owing to being provided with Speed sensing magnet steel in the end sides of final gear, the inner side of the gear chamber cover corresponding with the position of Speed sensing magnet steel is installed with Hall Speed sensing device.Therefore the device of a kind of accurate positioning motor operation range of the present invention, the actual travel speed of the timely Accurate Measurement electric bicycle of energy, thus the operation range of accurate positioning motor, make motor efficiency operation all the time, powerful and power saving, also have low cost of manufacture, the advantage such as easy for installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the device of a kind of accurate positioning motor operation range of the present invention, comprise gear chamber cover 1, output shaft 2, final gear 3, described final gear 3 is fixedly connected with one end of output shaft 2, the other end of output shaft 2 reaches the outside of gear chamber cover 1, described output shaft 2 forms rotatable cooperation by bearing 4 with gear chamber cover 1, the end sides of described final gear 3 is provided with Speed sensing magnet steel 6, and the inner side of the gear chamber cover 1 corresponding with the position of Speed sensing magnet steel 6 is installed with Hall Speed sensing device 5.
Should be noted that; the foregoing is only the preferred embodiments of the present invention, be not limited to the present embodiment, within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
