Performance Investigations of a Novel Rolling Traction CVT 2001-01-0874
The Milner CVT is a patented  rolling traction transmission offering advantages of high power density and simplicity of construction and operation.
A 90 mm diameter prototype variator is described which was sized for a maximum rated input power of 12 kW. Experimental data are presented demonstrating high efficiency and low shift forces. Resistance to overload torque is shown to be exceptional and preliminary durability trials indicate a highly viable concept for series production.
Based upon the measured data, characteristics of larger variators are predicted and prospects for automotive applications discussed.
