An infinitely variable cone-pulley transmission of the type including two pairs of cone pulley sheaves, each mounted on a respective shaft, a transmission member circulating between the pairs of pulley sheaves, a pressure cylinder at least partly defined by one pulley sheave of each pair and including a piston, a control valve supplying hydraulic pressure medium to each cylinder chamber, with the pressure being distributed between the two cylinder chambers in order to control the transmission ratio between the pulley sheave pairs, and a torque sensor associated with one of the shafts and active to control the hydraulic pressure in one of the chambers as a function of the torque on that one of the shafts, is supplemented by a two-part presser device which responds to the torque on one of the shafts in order to press one of the pulley sheaves on that shaft against the transmission member with a force which is a function of that torque. |
