Abstract
A continuously variable transmission (1) is provided with: an endless transmission (14) for transmitting a driving torque; a clamping force (13-1, 13-2) coupled with the endless transmission (14) for applying a clamping force thereon; a controller (15) coupled with the clamping force (13) for influencing the driving torque by controlling the clamping force applied on the endless transmission (14); and a clutch (16) coupled with the controller (15), whereby the controller (15) is arranged to control the clutch such that the clutch (16) is allowed to slip continuously. The net effect of a practical implementation of the transmission in a vehicle is a fuel saving which, if a slip of around 5 rpm is permitted, amounts about 3-4%.
