Study on the Cycloidal Planetary Gearing Transmission with Few-tooth-Difference in Electric and HEV for Low Speed Trucks

摘要

The research combines the scientific research reality, which meets to the characteristic and environment request of low speed trucks (LST) . According to the principle of component lectotype for Powertrain Coupling system of HEV, and the demands of performance parameter of LST about power, torque and speed when LST is under movement condition, this research is focus on the powertrain coupling system between engine electric motor and wheel which has carried on the optimized matching, the modeling simulation and the experiment. The article has determined one kind of new multipurpose design and development plan on the powertrain coupling system in electric and HEV for LST. It focal introduces the new powertrain coupling system based on the Cycloidal Planetary gearing transmission with Few-toothdifference (CPF) , which have applied in powertrain coupling system of the multipurpose light electric and HEV for LST. To provide the control strategy of clutches-brakes and brakes system with electromagnetic controlled in the CPF for developing controllers for motor, engine and central controller for E & HEV's LST power distribution. The findings indicated, the powertrain coupling system designs might satisfy the performance requirement for entire vehicle. The method and the obtained result provided basis design theory for LST and multipurpose light electric and HEV's. The technology has applied to LST in Ningbo Saiting Electric Bicycle Science & Technology CO., LTD, and has applied patent.
