System zur Einstellung der Spannung des Umschlingungsteils eines Umschlingungsgetriebes

摘要

The invention relates to a system for adjusting the voltage of a wrapped component of an infinitely variable speed transmission, preferably a transmission with a step-up ratio which can be adjusted in a stepless manner and one that is arranged in the drive train of a motor vehicle along with an engine and at least one clutch that can operate in various modes. The aim of the invention is to adjust the voltage according to the operational mode of the clutch. It is particularly advantageous to adjust the voltage of the wrapped component according to whether the step-up ratio of said infinitely variable speed transmission is regulated at a higher or lower step-up ratio. The voltage can also be adjusted according to the activation of an ABS, ASR or ESP system.
