摘要： The invention relates to a hydraulic arrangement for controlling a belt-driven conical pulley transmission, comprising a pump taking in a working medium from a working medium tank or via a radiator return valve from a radiator return line. The invention is characterized in that the radiator return valve (69) is configured as a minimum-pressure valve which keeps a connection between the radiator return line (31) and a pump intake line (102) closed by the radiator return valve until a specified minimum pressure is no longer met in the radiator return line, and which opens the connection between the radiator return line and the pump intake line by the radiator return line as soon as the specified minimum pressure in the radiator return line is exceeded.

摘要： Disclosed are methods for regulating or controlling the gear ratio of an automatic power-branched transmission (8), comprising a shaft driven by an engine (2), a variator (12), a wheel gear (14), a driven shaft, and at least two steering clutches (K1, K2), by means of which the variator (12) and the wheel gear (14) can be connected to each other in such a way that the regulating range of the variator (12) is traversed in one direction within a first range of gear ratios and is traversed in the opposite direction within a second range of gear ratios during traversing of the entire range of gear ratios of the power-branched transmission (8). Said gear-changing strategies result in reduced wear of the wrapping means and allow for comfortable changing between the gear ratio ranges. Also disclosed is the structure of advantageous automatic power-branched transmissions (8).

摘要： The invention relates to a clutch control device (1) for controlling the actuation of a hydraulically activated clutch having a valve device. In order to create a clutch control device which permits fast and precise actuation of the clutch, the valve device comprises a volume flow regulating valve (8) which permits both volume-flow-regulated filling and also volume-flow-regulated discharging of a hydraulic clutch actuating element (16).

摘要： The invention relates to a servo valve consisting of a housing which comprises a pressure valve piston movable therein, a valve spring interacting with said piston, terminals for lines comprising a main and slave cylinders and a pump which makes it possible to assist a clutch or brake pedal operation. In order to provide a minimum oil volume in the servo valve in the case of the system failure, said valve is embodied in such a way that the path of the pressure valve piston in the housing is restricted thereby.

摘要： A conical disk type flexible drive mechanism consisting of an input and output conical disk pair, containing a shaft, a single-piece or multi-piece fixed disk, a travel disk connected in a rotationally fixed and axially displaceable manner to the shaft, a support ring which is fixed to the shaft at a distance from the rear side of the travel disk such that it cannot be displaced axially, and at least one pressure chamber which is formed between the support ring and the rear side of the travel disk and which is provided with a hydraulic pressure medium by means of one or several ducts formed in the shaft leading into a peripheral surface of the shaft, whereby the pressure thereof can be modified in order to displace the travel disk. An end area of an inner surface of the travel disk guided on the shaft at a maximum distance from the fixed disk acts as an opening for the duct and ensures a hydraulic medium connection between the duct and the pressure chamber essentially by means of leakage gaps between the inner surface of the travel disk and the outer surface of the shaft.
