ABSTRACT:
In a toroidal transmission with a continuously variable power transmission ratio, which is adjustable by displacement of a power transmission roller arranged between toric disks along an axis X-X under the control of an adjusting unit including a hydraulic piston, the adjusting unit has a bush which serves on the one hand to seal off the working space and, at the same time, forms two slide surfaces one for the piston and another for the guide bush, all in a small support space pivotally supporting a support member for the power transmission roller.
