ABSTRACT:
A continuously variable transmission, provided with two adjustable pulleys, each pulley comprising a pair of mutually displaceable essentially frusto-conical pulley sheaves having a radial dimension provided on a pulley shaft, each sheave having a sheave face, whereby the sheave faces of a pulley are mutually oriented at a pulley angle, and with an endless flexible belt for transmitting torque comprising two lateral side faces, which are mutually oriented at a belt angle (alpha) such that the flexible belt tapers radially inwardly and which are intended for interacting with the sheave faces of a pulley under the influence of a clamping force to be exerted on the flexible belt by the sheaves. The belt angle is marginally, but notionally, larger than the pulley angle (beta) of at least one pulley for at least a substantial part of the radial dimension of the pulley sheaves.
