The Optimal Design and Controlled Strategy of the Planetary Gearing Powertrain Coupling System with Few-Tooth-Difference in Electric and HEV for All-Terrain Vehicles

Abstract

The research combines the scientific research reality, which meets to the characteristic and environment request of all-terrain vehicles (ATV). According to the principle of component lectotype for Powertrain Coupling system of HEV, and the demands of performance parameter of ATV about power, torque and speed when ATV 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 ATV. It focal introduces the new powertrain coupling system based on the Cycloidal Planetary gearing transmission with Few-tooth-difference (CPF), which have applied in powertrain coupling system of the multipurpose light electric and HEV for ATV. 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 & HEVs ATV power distribution. The findings indicated, the powertrain coupling system designs might satisfy the performance requirement for entire vehicle in wild beach. The method and the obtained result provided basis design theory for ATV and multipurpose light electric and HEVs. The technology has applied to ATV in Ningbo Saiting Electric Bicycle Science & Technology CO., LTD, and has applied patent.

A Novel Planetary Gear Hybrid Powertrain

“…In this situation, the assumption of torque is the same as above, and the relation of the engine rotation speed Ne, the motor 1 rotation speed N 1 and the motor 2 rotation speed N 2 is the same as formula (1). Fig.…”

“…To reduce engine emissions and the dependence on fossil fuel energy, researchers and vehicle manufacturers have started projects about hybrid powertrain systems. A Few-Tooth-Deference Planetary Gear Powertrain is developed for all-terrain vehicle and it was proved practicable in application example [1] . A hybrid powertrain system based on K-H planetary gear and hole-pin type output mechanism is developed to fit for low speed vehicle [2] .…”
