Abstract: The invention relates to a transmission chain for transmission of torque between one pair of driving conical discs and another pair of driven conical discs in a continuously variable transmission. According to the invention, the chain is composed of identical, interlocking links in the form of blocks, the end surfaces of which are bevelled at an angle to fit the conical discs. Said blocks have opposite longitudinal sides having means with rolling contact surfaces for engagement with rolling contact surfaces on corresponding means of the adjacent links.
