Analysis of belt behavior for an automotive V-belt CVT
차량용 V-벨트 CVT의 벨트거동해석
Abstract
The behavior of a V-belt CVT was investigated both analytically and experimentally. It was found that as the torque load increased, the belt radial displacement increased in inward radial direction for the driven pulley while the radial displacement decreased slightly and increased for the driver pulley. The relative belt displacement for the driver was negligible compared with that of the driven. The experimental results were in good accordance with the theoretical results except for the inlet and exit region of the pulley. The speed ratio-torque load-axial force relationship derived from the belt behavior analysis also showed good agreement with the experiment. It is suggested that the results of this paper can be used as basic design informations of a V-belt CVT.
