Abstract

A belt-driven conical pulley transmission includes a first pulley sheave pair arranged on the first shaft, a second pulley sheave pair arranged on the second shaft, a belt means, a first slide rail, and a second slide rail. Each pulley sheave pair includes a first conical pully displaceable along a respective shaft axis and a second conical pulley fixed along the respective axis. The belt means is displaceable in a radial direction along respective contact faces of the pulley sheave pairs from an inner position to an outer position. The belt means includes a traction strand extending through an intermediate space between the first pulley sheave pair and the second pulley sheave pair, and a thrust strand extending through the intermediate space. The first slide rail is guides the traction strand and the second slide rail is designed different from the first slide rail and guides the thrust strand.
