Abstract
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 2000 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.
