Characteristic analysis and simulation of a new-type continuously variable transmission carried in EV
摘要
Abstract
As far as the energy-saving requirements of the Transmission system carried in electric vehicles(EV) is concerned, this paper proposes a new-type planetary gear continuously variable transmission(P-CVT) carried in EV. The relations of the rotation speed and the torque among its basic components are derived by analyzing the Mechanical structure of P-CVT,and these two relations are proved from the perspective of energy conservation. Finally, dynamics simulation has been done on the relations derived above with ADAMS. The simulation results show that the input and output torque of the transmission do not have contact with the speed ratio directly, and high-speed and large-torque output can be achieved under conditions of continuously variable transmission. This transmission has characteristics of high energy-efficiency, stable adjustment, and simple control.关键词
