Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the electronics handle circuit diagram in the present invention.
1. fixed supports in figure, 2. wheel hub motor, 3. load loading wheel, 4. index steel wire, 5. actuator crank, 6. back-moving spring, 7 exchange reducing motors, 8. eccentric gearing wheel, 9. gravity counterweight, 10. electric machine controller, 11. proximity transducers, 12. electronic counters, 13. electronics handles.
Embodiment
The present invention is further detailed explanation with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
as Fig. 1, electric bicycle hub motor brake band of the present invention shown in Figure 2 carries the embodiment of proving installation, a kind of electric bicycle hub motor brake band carries proving installation, comprise fixed support 1, be provided with the wheel hub motor 2 with cover tire on fixed support 1, above described wheel hub motor 2, close contact is provided with and loads loading wheel 3, also be provided with clamping device on described wheel hub motor 2, clamping device is connected with gearing by index steel wire 4, described wheelwork also is connected with control circuit, described clamping device comprises detent and actuator crank 5, described actuator crank 5 also is connected with back-moving spring 6, described actuator crank 5 is connected with index steel wire 4, described wheelwork comprises interchange reducing motor 7, eccentric rotary wheel 8 and gravity counterweight 9, described gravity counterweight 9 is connected with index steel wire 4, described control circuit comprises electric machine controller 10, proximity transducer 11, electronic counter 12 and electronics handle 13.
principle of work: exchange reducing motor 7 energising rotations, drive eccentric rotary wheel 8 and make circular motion, promote the gravity weights 9 of suspension constantly up and down, gravity weights 9 is time tension index steel wire 4 down, make actuator crank 5 begin braking, when gravity weights 9 up the time, back-moving spring makes the crank take-off the brake, wheel hub motor 2 is in the process of starting accelerated service, the cover tire of wheel hub motor 2 is loaded loading wheel 3 and forces together tightly, driving loading loading wheel 3 rotates together, when detent is braked, rely on the inertia that loads loading wheel 3 large quality, make the piece of stopping of brake inside produce friction brake force, the size of this damping force has reflected the length of braking time, also tested the braking ability of detent.This device can be simulated the overall process of electric bicycle brake when being braked realistically;
The course of work of control circuit: proximity transducer 11 is arranged on the below of gravity weights 9, and when gravity weights 9 moved down proximity transducer, in brake, the high frequency oscillator in sensor was because of the eddy current energy consumption failure of oscillation of weights, and sensor is exported 0 volt; When moving away sensor on gravity weights 9, in the time of releasing of brake, high frequency vibrating shake device is resumed work, and sensor output voltage at this moment is 12 volts.The present invention has designed an electronics handle circuit the simplest, and with turn-offing and the starting control end, is arranged between electronic sensor and electric machine controller.When sensor was exported 0 volt, the voltage on capacitor C outputed to the V of electric machine controller by diode D rapid discharge
0Signal is 0 volt, motor stalling; When sensor is output as 12 volts, due to the diode reverse cut-off, 4.2 volts of logical rear W of power supply
1, R
1To the capacitor C charging, triode forms emitter follower, so electronics handle output voltage V
0According to different variation of resistance of adjustable resistor W, this voltage is defeated by electric machine controller, reaches the purpose of regulating the wheel hub electromotor velocity.R in figure
3In order to regulate last V
0Value.Sensor is exported the rising edge flip-flop number of 12 volts simultaneously, completes to add 1 function.
