Abstract
The utility model provides a device for accurately positioning operating gears of a motor. The device comprises a gear chamber cover, an output shaft and a final gear; the final gear is fixedly connected with one end of the output shaft, the other end of the output shaft stretches out the gear chamber cover, and the output shaft is in rotatable fit with the gear chamber cove through a bearing; and a side surface of an end portion of the final gear is equipped with a rotating speed induction magnetic steel, and an inner side, corresponding to the position of the rotating speed induction magnetic steel, of the gear chamber cove is fixedly equipped with a Hall rotating speed inductor. With the device for accurately positioning the operating gears of the motor, an actual driving speed of an electric bicycle can be accurately determined timely, and therefore the operating gear of the motor can be accurately positioned to make the motor to efficiently operate all the time; and the device is powerful and power-saving, and is also advantaged by low manufacturing cost and convenient installation and the like.
Description
Technical field
The utility model relates to a kind of device, especially a kind of device of accurate positioning motor work gear.
Background technology
When the conventional electric bicycle that shift motor is installed is used, its machine operation gear obtains by measuring motor rotary speed, when electric bicycle is during at descent run state, motor may stop operating, electric bicycle, by idle running under self existing speed, causes the work gear of motor incorrect.
Utility model content
Problem to be solved in the utility model is the deficiency overcoming in background technology, a kind of device of accurate positioning motor work gear is provided, this device, by measuring the rotating speed of final output gear, accurate positioning motor work gear, make motor always work in high efficiency section, thereby reach powerful power saving again, make the electric bicycle comfortable effect of riding.
For addressing the above problem, the utility model is taked following technical scheme:
The device of a kind of accurate positioning motor work gear of the present utility model, 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 induction of Hall Speed sensing device is arranged on the Speed sensing magnet steel on final gear, obtain the true travel speed of electric bicycle, when the travel speed of electric bicycle is when a certain numerical value is following, automatically being adjusted to one grade travels, surpassing auto-changing travels to second gear, when vehicle at full throttle travels, controller can go out instant load by automatic decision, and automatic adjusting enters third gear and travels.If travel speed is in a certain value critical condition, user can use one grade of one grade of control button maintenance to travel.
The device of a kind of accurate positioning motor work gear of the present utility model, because the end sides at final gear is provided with Speed sensing magnet steel, the inner side of the gear chamber cover corresponding with the position of Speed sensing magnet steel is installed with Hall Speed sensing device.So device of a kind of accurate positioning motor work gear of the present utility model, energy is the actual travel speed of Accurate Measurement electric bicycle in time, thereby the work gear of accurate positioning motor, make motor efficiency operation all the time, powerful and power saving, also there is low cost of manufacture, the advantage such as easy for installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
