摘要:
A torque sensitive squeeze control apparatus for a variable ratio pulley drive apparatus has a fluid translating unit (26), such as a pump, disposed in the input torque path (30). One member (28) of the fluid translating unit is rotated by the input drive shaft (30) while another member (24) is fixed for rotation with an input pulley shaft (22). If a rotational difference between the input drive shaft and the input pulley shaft is present, the fluid translating unit is effective to increase the pressure in the squeeze control piston of the input pulley thereby increasing the torque capacity of the pulley. A speed differential will occur when a torque difference between the two shafts is present. The hydraulic control for the output pulley (14) is via a controlled servo valve mechanism (52) which permits operator control of the drive ratio between the pulleys independently of the squeeze force on the input pulley.
摘要(中):
用于可变比率皮带轮驱动装置的扭矩敏感挤压控制装置具有布置在输入扭矩路径(30)中的诸如泵的流体转换单元(26)。 流体平移单元的一个构件(28)通过输入驱动轴(30)旋转,而另一个构件(24)被固定以与输入滑轮轴(22)一起旋转。 如果存在输入驱动轴和输入滑轮轴之间的旋转差异,则流体平移单元有效地增加输入滑轮的挤压控制活塞中的压力,从而增加滑轮的扭矩容量。 当存在两个轴之间的扭矩差时,将发生速度差。 用于输出滑轮(14)的液压控制通过受控伺服阀机构(52),其允许操作者独立于输入滑轮上的挤压力来控制滑轮之间的驱动比。
