Abstract

See full text

A method is disclosed for controlling a drill-free curve-CVT including a ring wheel, a set of planet wheels, and a sun wheel, wherein the ring and sun wheel are clamped together. The normal forces between the ring and sun wheel on the one hand and the planet wheels on the other hand are well defined when the transmission ratio is constant. The normal forces for constant ratio are called the static values. The method is configured so that during a continuous increase or decrease of the transmission ratio, any force component added to the static values of the first and/or the second normal force is either zero or smaller than a predefined force component to maintain a microslip condition of the rolling contacts between the planet wheels and the ring and sun wheels. This control of the forces is applied regardless of the speed of the ratio change.
