概要

This paper is concerned with noise generation mechanisms of a dry hybrid belt for CVT systems. The dry hybrid belt has been developed and used in CVT systems in sub-compact cars. The system without lubrication and hydraulic apparatus has very high transmission efficiency, which improves mileage. The higher fuel consumption efficiency has been attained in comparison with manual transmissions. Furthermore, the system responses very quickly and does not take up large space in the engine design. The hybrid belt consists of a pair of tension members inserted to many lateral H-shaped blocks. Since the hybrid structure is completely different from those of conventional rubber V-belts, the mechanism of noise generation is also very unique. In this study, some noise mechanisms will be elucidated experimentally using belts with different dimensional parameters and by means of strain measurement of the blocks on running.
