METHOD FOR DETERMINING THE ROTATIONAL SPEED OF A PART, ASCERTAINING THE SLIPPING OF A CONTINUOUSLY VARIABLE TRANSMISSION (CVT), AND FOR CONTROLLING A CVT, AND A CONICAL DISC FLEXIBLE DRIVE TRANSMISSION

摘要

The method involves determining the revolution rate of the part from a number of components in a system subject to oscillations that are coupled in relation to their rotatability by measuring the revolution rate of a component in or at an oscillation node and computing the revolution rate of the part from the measured revolution rate and the transmission ratio between the component and the part. AN Independent claim is also included for the following: a method of determining the slipping of a continuously variable transmission or CVT, a conical disk gearbox and a method of controling a CVT gearbox.
