Transmission chain for a cone pulley transmission

Transmission chain for a cone pulley transmission comprising a number of links mutually coupled by elongate pins which extend through the links and each of which has first axial end faces engaging facing surfaces of a cone pulley, a plurality of elongate strip-shaped interpieces also extending through the links, said interpieces being shorter than said pins and having second axial end faces spaced from the facing surfaces of a cone pulley, said pins and interpieces having co-operating side surfaces engaging in a rolling motion with respect to each other, each link accommodates non-rotatably with respect thereto a said pin and in the longitudinal dimension of the link at a distance from said pin an interpiece, each pin having an active side surface directed to an active side surface of an opposite interpiece, there is in each link adjacent each active side surface of a pin and an interpiece respectively sufficient free space to accommodate an interpiece or pin respectively which is coupled to an adjacent link during the movement thereof, there being adjacent sets of links coupled mutually in the longitudinal direction of the transmission chain such that one pin in a first link co-operates with a rolling contact movement with an interpiece in an adjacent, staggered link.
