Calculation and Analysis of Traction Infinitely Variable Transmission

2011 Second International Conference on Digital Manufacturing & Automation, 2011
Traction oil film thickness calculation is done on a kind of continuous velocity transmission which is named traction infinitely variable transmission (TIVT). It is proved that transmission type of TIVT is traction drive rather than friction drive through design on roughness, material of parts and traction oil.
