Described car body fixed mechanism is installed on the top of platform, and this car body fixed mechanism is made of the saddle briquetting 14 of the stand 4 that is packed in described platform top, the pressure cylinder 15 that is installed in the stand bottom and pressure cylinder cylinder bar lower end.Pressure cylinder upper end installs two sliding sleeves 2 side by side, and these two sliding sleeves are slidingly mounted on two crossbeams 1 on the stand.Pressure cylinder is cylinder or hydraulic cylinder.
As shown in Figure 2, control module comprises signal processor 9 and the drum braking controller that is connected with this signal processor, drum braking controller synthesis sensor, application of force electric machine controller, application of force electromechanical transducer, brake lever damping force sensor, electric bicycle brake lever switch, front derailleur position transducer, Rear Derailleur position transducer, signal processor also connects comparer.The signal processor of control module also connects single-chip microcomputer, and single-chip microcomputer connects display unit, and keyboard connects single-chip microcomputer by the display process module.This display unit is a display screen 3, and this display screen is installed in a side of platform by support 5, and display screen is connected with keyboard.Control module comprises that also one is installed in the tachometer generator on the electric bicycle driving wheel, and this tachometer generator is connected with signal processor.Signal processor connects EmS and shift switch.
Drum braking controller and the rotating shaft connection of testing cylinder are installed drum braking controller synthesis sensor on the drum braking controller, be used to transmit output torque, rotating speed and the vehicle speed signal of driving wheel.
Application of force motor connection application of force electric machine controller and application of force electromechanical transducer.
Brake lever damping force sensor is installed on the brake lever.
Front derailleur position transducer and Rear Derailleur position transducer are installed in position, chain front and rear part respectively.The front derailleur position transducer is a chain seven speed transmissions position transducer, and the Rear Derailleur position transducer is chain nine gear gearbox position transducers.
The mode of operation of this electric bicycle power-assisted, speed change instructional device is:
⑴, electric bicycle 13 is fixed on the platform, engaged wheel adopts wheel to step up mechanism and fixes, driving wheel with test cylinder and contact.
⑵, saddle are pushed down with the saddle briquetting, and pressure fixes on the adult human body weight of 75Kg(simulation).
⑶ the axis of, electric bicycle is connected with the output shaft of application of force motor, and application of force motor can be adjusted up and down by adjustable motor frame, so that connect the vehicle of different model.

⑹, in the suitable position of the driving wheel of tested vehicle a tachometer generator is installed, in order to measure the revolution of tested vehicle driving wheel.
The principle of work of this electric bicycle power-assisted, speed change instructional device is:
When electronic white driving driving wheel rotates, can drive the test cylinder rotates, and cylinder is when rotating, the drum braking controller is passed to signal processor with related data (output torque of driving wheel, rotating speed and the speed of a motor vehicle), signal processor transfers to single-chip microcomputer with signal, and is shown by display screen;
During mechanical speed change handle on stirring handlebar, along with application of force motor (band speed change) drives, the axis of electric bicycle rotates, and the gearshift device of mechanical speed change mechanism is allocated to desired location with chain, display screen can demonstrate Middle axle crank rotate a week be driven wheel rotate the number of turns the speed ratio value.
When application of force motor (band speed change) drove the axis rotation, display device can demonstrate the input torque of motor and the output torque of driving wheel, was demonstrated the ratio of the two simultaneously by display screen, i.e. the efficient of electric bicycle.
When pinching the brake lever of controlling and driving wheel, when driving wheel and test cylinder stop operating, can the damping force of wheel be passed to signal processor by brake lever damping force sensor, calculate the braking distance of electric bicycle when the various speed of a motor vehicle by single-chip microcomputer, and show by display screen.
Former and later two positions at the chain of the tested electric bicycle electronic white driving of speed change gear (be mainly band) are installed front derailleur position transducer, Rear Derailleur position transducer respectively, and front derailleur position transducer, Rear Derailleur position transducer can be responded to the position of chain when electronic white driving test, by the conversion of position position signalling are passed to signal processor.
When application of force motor in the running, pinch the electric bicycle brake lever, application of force motor can be stopped power supply and quit work.
Signal processor is the center processor of whole platform, signal processor is responsible for the signal transmission of various piece and is handled, single-chip microcomputer is the input and the processor of display part, and the signal command of received signal processor during work belongs to the one-level part of signal processor.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification all are possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
