Coupling system with hydraulically actuated multiple coupling device has pressure sensor arrangement that detects only one pressure level determining coupling arrangement actuation state

摘要

The system has a coupling device (202) and an actuating arrangement (208,304,214,216,ECU) for hydraulic actuation of the coupling device, a number of coupling arrangements (204,206), each associated with a gearbox input shaft, at least one hydraulic medium supply and a pressure sensor arrangement (322) that detects only one pressure level determining the state of actuation of an associated coupling arrangement. -
