摘要
牵引式无级变速器具有承载能力强、效率高、平稳性好等优良的传动特性 ,是除金属带式无级变速器外 ,可用于车辆传动的又一种无级变速器 ,适合于较大排量车辆上应用。在对弧锥型牵引式无级变速器的基本结构、传动变速原理及变速控制系统进行分析的基础上 ,推导了速比变化关系、接触压力与传递扭矩的关系以及速比反馈伺服控制阀 -液压缸 -滚轮系统的传递函数 ,建立了速比控制动态特性的数学模型 ,并给出了系统框图 ,为进行系统的性能分析及仿真研究奠定了基础。
The traction drive continuously variable transmission is another kind of advanced transmission device for vehicle beside the metal pushing V_belt type CVT. It provides excellent driving performances including powerful driving capacity, high efficiency, good smoothness and economy, etc. The basic structure, transmission principle and the hydraulic servo control system of traction drive CVT are described. The mathematical model of the system is established. The study of this project provides the academic bases of further studying on the dynamic characteristics of CVT and vehicle.
