摘要
无级变速器(CVT)是一种理想的变速器,但由于不能承受大扭矩的冲击,金属带容易损坏而没有被广泛的应用。本文研究的是一种新型的高扭矩无级变速器(HCVT),在分析HCVT的工作原理和基本结构的基础上,对传动带进行静态力学分析;在多学科动力学仿真平台SimulationX上,搭建HCVT的三维动力学模型进行运动学分析。分析表明该HCVT具有高扭矩,高效率的特点,其传动比可以在一定范围内连续变化,且控制过程容易实现,其最高扭矩通过增加传动盘的直径可以达到2 000 Nm,传动效率为94%。因此该HCVT可适用于各类型车辆,尤其是大中型的城市公交车和工程车辆。
The continuously variable transmission（CVT） is an ideal transmission.But,it has not been used widely because it can not bear the impact of high torque and its metal belt may be damaged easily.This paper presents a new high torque continuously variable transmission（HCVT）.Analyzed the principle and basic structure of HCVT,the static mechanical performance is investigated for the transmission belt.Then,its kinematic performance is analyzed by using 3D dynamic model built on the basis of dynamic simulation platform SimulationX.The analysis results show that HCVT is characterized by high torque and efficiency,and its speed ratio can be controlled easily and continuously.Its maximum torque can reach to 2 000 Nm by increasing its driving disc＇s diameter and transmission efficiency can be up to 94%.It can be applied to all types of vehicle,especially in large and medium transit bus and engineering vehicle.
