ABSTRACT:
The invention concerns a stepless variable belt transmission with pulleys which comprise two axially movable conical halves. The displacement of the pulley halves is effected by hydraulic piston-cylinder units rotating along with the pulleys. At least one hydraulic piston-cylinder unit is provided with a compensation chamber wherein a pressure is built up as a function of the speed. According to the invention the compensation chamber communicates with a closable opening with the cylinder chamber by means of which the pulley halves are relatively moved.
