A continuously variable transmission (CVT) will contribute to improve the fuel economy of automotive propulsion systems The half toroidal traction drive is a rolling element type CVT with a feature of low spin in contact area. In this report, a theoretical estimation method of speed and torque transmission efficiencies is shown by making a shear model of traction fluid in EHL contact area. Theoretical results are compared to test results of a prototype of nominal input torque capacity of 120 N·m, rotational speed of 5000 rpm and maximum speed ratio of 6.25.
