Abstract:
A continuously variable transmission (1) comprising a rotatable drive (2) and driven pulley (5), each of which having an axially displaceable sheave (4, 6) for transmission ratio control by varying the running radii of a power transmission belt (8) running between the sheaves (3, 4; 6, 7); and a lubrication nozzle (9) having an output (O1, O2) for supplying a jet of lubricating fluid to a midpoint (M1, M2) at the inner side of the belt (8),characterised in that at least one output (O1) of the lubrication nozzle (9) at the driven pulley (5) is directed to the midpoint (M1) of the transmission belt (8) while running in a transmission ratio TOP area (A), the lubrication nozzle (9) has two outputs (01,02) and the lubricating fluid yields through the outputs (01,02) per unit time are approximately equal, wherein the TOP area is a position of the transmission belt where a maximum power is transmitted by the transmission belt (8).
