    摘要: A hydraulic system of a transmission, for an automatic transmission of a motor vehicle, having several pressure circuits which can be loaded with hydraulic fluid from a pressure source and in relation to the supply of different areas of the transmission are differently prioritized. The pressure in the pressure circuits is adjustable according to a system valve and one of the pressure circuits comprises a cooling device for the hydraulic fluid and a lubrication circuit located downstream of the cooling device. Between the cooling device and the lubrication circuit is provided a bypass pipe, blockable via a valve unit, which can be controlled via the valve unit so that the hydraulic fluid flow rate to be passed via the cooling device can be adjusted without changing the hydraulic fluid flow rate to be fed to the lubrication circuit.

    摘要: A device for determining an operating state of a bi-directionally actuated hydraulic adjusting device of a transmission shifting element, which pressurizes active surfaces of a piston. The piston is biased to opposite end positions depending on which of a first active surface or a second active surface is pressurized with high pressure. The areas of the adjusting device, which can be pressurized with the pressure at the active surfaces of the piston, are connected with one another in positions of the piston element, between the end positions, via a throttle device. One of each area can be coupled for adjustment of the piston with the high-pressure area, and the other area with the low pressure area. An additional throttle device is provided upstream of the low pressure area and a pressure measuring device is provided upstream of the additional throttle device.

    摘要: A transmission device (1) with a hydraulic system (4) comprising a main transmission pump device for supplying various transmission components with hydraulic fluid. The main transmission pump device is driven by torque applied to the transmission input shaft (2). A force flow between the transmission input shaft (2) and transmission output shaft (3) is produced by various hydraulically actuated transmission components. When the hydraulic system (4) is not supplied by the main transmission pump, the force flow is interrupted. The hydraulic system (4) has an auxiliary pump device (5) by virtue of which the hydraulic system (4) too can be supplied with hydraulic fluid. The auxiliary pump device (5) is driven by torque applied to the transmission output shaft (3) at least when the force flow is interrupted.
