CVT(无级变速器)提供的连续速比间的要求有限。目前已经开发了许多稳态模型,说明CVT的动力学,但它们不能阐述带高速时惯性对CVT性能产生的影响。本研究将着重于开发一种详细的非稳态模型来探索和了解不同的动力特性对金属推块V型带CVT的相互影响,本文采用连续的库仑(Coulomb)摩擦理论近似模拟带和带轮之间的摩擦。许多研究旨在观测惯量和滑动情况下的载荷状态对CVT传递转矩能力的影响。讨论了计算简图数学模型和不同载荷方案的相应结果。该结果表明惯性对CVT转矩传递特性的显著影响。
The CVT (Continuously Variable Transmission) offers limited requirements between consecutive speed ratios. Many steady-state models have been developed to illustrate the dynamics of CVTs, but they can not address the effects of inertia on CVT performance at high speeds. This study will focus on the development of a detailed unsteady model to explore and understand the interaction of different dynamic characteristics on the metal push-block V-belt CVT. In this paper, a continuous Coulomb friction theory is used to simulate the belt and pulley The friction between. Many studies aim to observe the effect of load conditions on inertial and slip conditions on the ability of CVT to transmit torque. The corresponding results of calculating the mathematical model of the sketch and the different loading schemes are discussed. This result shows the significant influence of inertia on the CVT torque transfer characteristics.
