    摘要: A belt-type continuously variable transmission consisting of: an input/drive shaft with a rotational axis; an output/driven shaft with a rotational axis; a first variable speed pulley on the input/drive shaft and having a first pulley part fixed against axial movement relative to the input/drive shaft and a second pulley part movable axially relative to the first pulley part, with the first and second pulley parts cooperatively defining a belt-receiving groove; a second variable-speed pulley on the output/driven shaft and having a third pulley part fixed against axial movement relative to the output/driven shaft and a fourth pulley part movable axially relative to the third pulley part, with the third and fourth pulley parts cooperatively defining a belt-receiving groove; a fluid cylinder; structure for shifting the second pulley part axially relative to the first pulley part in response to a change in pressure in the fluid cylinder; a fluid reservoir on the first variable-speed pulley for rotation with the input/drive shaft; structure for sensing the rotational speed of the fluid in the fluid reservoir as the input/drive shaft is operated; and structure for communicating the sensing structure with the fluid cylinder to establish an equilibrium therebetween and to thereby vary the fluid pressure in the fluid cylinder as an incident of a change in the rotational velocity of the input/drive shaft and the fluid in the fluid reservoir.
