Study of the Stable Control System of a Half-Toroidal CVT During Mode Change - A Comparison of Hydraulic and Mechanical Loading Devices

摘要

In this paper, we compare some CVT systems and show that NSK's new coaxial power-split CVT has potential for higher efficiency, a wider ratio range, and is more compact. We have analyzed the influence of elastic deformation, clearance, and inertia during load transmission. Furthermore/we have compared hydraulic and mechanical loading devices, and have analyzed how they influence behavior during static and dynamic load transmission. These have been confirmed both theoretically and experimentally.
