Abstract
Transmission chain with links coupled by rocker assemblies with each two longitudinal pins which roll over each other and of which one cooperates in a force transmitting way with the opposite pulleys of a pair of cone-shaped pulley sheaves, and these pins have a first dimension (b) in the longitudinal direction, a second dimension (h) perpendicular to the longitudinal direction and to the running direction of the chain and a third dimension (d) cross-wise to the longitudinal direction and in the running direction, in which for each value of the first dimension (b) both other dimensions (h) and (d), respectively, are such that the ratio between this dimension (b) and each of the other dimensions, is, taking into account the expected loading of the chain, as small as possible.
