摘要：
There is provided a method of changing regime in a continuously variable ratio transmission having a variator and a continuously variable ratio transmission having a variator. The continuously variable ratio transmission having a variator (20) and a gearing through which the variator can be coupled between a rotary input and a rotary output of the transmission in either of a low regime and high regime, a clutching (80,82) arrangement for selectively engaging low regime and high regime so that a change of regime can be effected by engaging one regime and disengaging the other, and a hydraulic control comprising a variator control valve arrangement (52,54) for applying an adjustable control pressure to the variator and a hydraulic circuit which communicates with the variator, the transmission being characterised by provision of means for causing pressure in the compliance to be raised prior to engagement of the new regime in a regime change.
摘要（中）：
提供了一种具有变速器和具有变速器的无级变速比变速器的无级变速器变速状态的方法。 无级变速器具有变速器（20）和齿轮传动装置，变速器可以以低方案和高方式以任何一种方式耦合在传动装置的旋转输入和旋转输出之间;离合器（80,82） 用于选择性地接合低制度和高制度，使得可以通过接合一个制度并使另一个制动器分离来实现制动的改变;以及液压控制器，其包括用于向变速器施加可调节的控制压力的变换器控制阀装置（52,54） 以及与变速器通信的液压回路，所述变速器的特征在于，在新制度参与制度改变之前提供用于使履约压力升高的装置。
