Abstract
A transmission system includes at least two continuously variable transmission units of a toroidal or V-belt type, arranged in parallel with each other between a common driving member and a common driven member, so as to provide parallel equal drive paths. Both units are coupled with each other so that operating conditions are equal, and connected with a single common control valve which is designed to control shift actuators of both units equally.
