In accordance with the national standard GB17761-2024 "Technical Specification for Safety of Electric Bicycles", the power assisted driving device should be able to achieve 

and maintain the vehicle speed between 24.5km/h and 25.5 km/h, with adjustable speed, stable output of the driving system, stable driving speed, and the vehicle should not slip during the test on the test bench

1. Control mode: PLC control, touch screen human-machine interface operation;

2. Testing station: 1 station;

3. Frame structure: Steel Fangtong adopts skeleton spraying technology, with independent operation display control box;

4. Drive mechanism: Double flywheels are installed at the bottom, and the rear flywheel is driven by a 1.5KW servo+turbine reducer. The front flywheel rotates automatically,

 and the center distance between the front and rear flywheels can be manually adjusted, with a maximum distance of 600mm. It meets the requirements of 800-1250mm

5. Flywheel technology: surface coated with adhesive, meeting the standard requirements for friction coefficient;

6. Handle mechanism: motor-driven+universal joint mechanism, auxiliary cylinder braking;

7. Fixed mechanism: The front and rear wheels of the sample are fixed with adjustable fixtures, and the sample is manually transported to the flywheel;

8. Speed measurement mechanism: using a wire encoder to transmit data and a touch screen to display speed; Rotary encoder or laser velocimetry

9. Test speed: interval and auxiliary mechanism ZUI high speed measurement 25.5km/h;

10. Load configuration: Using canvas bags filled with 80kg steel balls to suspend the saddle on both sides;

11. Equipment power supply: AC220V 50Hz.
