ABSTRACT:
To reduce the noise level of chains connecting cone pulleys in variable ratio transmissions, in which chain links (1, 15, 43) are joined by rocker elements (3, 16, 44), frame bodies or frames elements (7, 8, 21, 22, 23, 30, 31, 32, 33, 46, 51, 64, 65) are positioned between adjacent hinge joints formed by the rocker elements, located transversely to the chain, the frame bodies having lateral engagement surfaces (11, 24, 25, 26, 55, 56, 57, 66, 67) located laterally adjacent to the sides of the outermost chain link elements for resilient frictional engagement with the facing surfaces of the cone pulleys (12, 40, 41) of the transmission, so that the transmission will be engaged by the engaging surfaces (45) of the rocker elements as well as the engagement surfaces of the frame bodies. The frame bodies are retained on the chain by force engagement with the chain link elements and/or the rocker elements.
