Abstract: The actuating arrangement includes a torque transmitting system that includes a first device for initiating, discontinuing or regulating the transmission of torque. A transmission includes a second device for initiating a gear shifting operation within one of a plurality of gear shifting paths. The transmission further includes a third device for initiating the gear ratio selecting operation among the gear shifting paths. An electronic control unit is operatively connected to at least one actor. The at least one actor activates in a predetermined manner, one of the first device, second device and third device for the initiation of the transmission of torque, gear shifting or gear ratio selecting operation.
Abstract: A hydromechanical torque sensor having several plenum chambers can be utilized to transmit torque between the driving and driven parts in the power train of a motor vehicle as well as to make necessary adjustments in a hydraulically adjustable transmission. To this end, the plenum chambers of the torque sensor can be connected to or sealed from each other. The torque sensor and the transmission can receive fluid from discrete sources or from a single source by way of suitable valves.
