摘要： The invention relates to a continuously variable transmission. The continuously variable transmission according to the invention is designed such that in operating conditions to be defined in more detail the transmission ratio is kept essentially constant, in particular for travelling through bends, on inclines, in case of an emergency stop and during a transmission overspeeding. The constant transmission ratio is obtained while the input r.p.m. of the transmission is changing.

摘要： A hydraulic controller (10, 10a, 10b) for a continuously variable transmission (12) is proposed. Using a pump (42), the delivery chambers (24, 26) of a first and second adjusting device (14, 16) are acted upon to alter the transmission ratio of the transmission (12). The valve (36, 36a, 36b), which can be controlled using a pressure drop created at a throttle position (50), serves to control the pressure in the delivery chamber (24). According to the invention, additional means are provided to prevent an adjustment of the transmission (12) in the “low” direction in the (N) operating state and, as necessary, in the (P) and (N) operating states.
