Research on the Efficiency of Metal Belt Continuously Variable Transmission for Vehicle

Article Preview

Abstract:

The efficiency of continuously variable transmission for vehicle is an important factor impacting on its performance, many kinds of power loss in process of shifting down and up are analyzed by means of theoretical and experimental ways, it can be seen that the power loss between metal-belt and pulley, which includes three items of loss: the entering and out of pulley; the slip between elements and surface of pulley; the slip of between steel bands and elements, is a major one. The calculating formulas are founded. The comparison of calculating results with experimental results under the different ratio, it is good coherence between them which has a guiding function for the design of TCU.
