摘要: 通过分析金属带式CVT装置传动过程中金属块、金属环和带轮的工作原理和受力关系,导出了求解金属块挤推力、金属环张力及带轮轴向力的数学式。给出了带轮最小轴向力的求解方法,对不同工况下金属环张力、金属块挤推力和带轮轴向力的大小进行了求解,获得了相应的载荷分配及受力规律。为无级变速器的强度设计和液压系统的控制奠定了理论基础。

Abstract: By analyzing the working forces on blocks, rings and axial forces on pulleys of the metal pushing –belt during torque transmitting, formulas for calculating the working forces and the axial forces on pulleys are deduced, and the method for deciding the minimal axial forces on pulleys is established. According to the calculating results of the working forces and the axial forces on pulleys under different working conditions, the rule of the load distribution between blocks and rings is got. The research results can be used for strength design and the hydraulic system control of CVT gearbox.
