  • Publication number: 20170191560
    Abstract: A dual clutch transmission device is disclosed. The dual clutch transmission device has a transmission device with a transmission housing, with a coupling housing positioned within the transmission housing and with a lubricant reservoir to receive a lubricant for the transmission device, which includes an oil trap ring connected at least indirectly with the transmission housing, which at least partially surrounds the coupling housing. The oil trap ring has a side facing the coupling housing which is primarily designed as an oil guide surface and which has at least one groove which is intended to guide lubricant into the lubricant reservoir. The dual clutch transmission device also has a gear set with a dry sump to lubricate the gear set.

  • Patent number: 6595077
    Abstract: A change-speed gearbox has an input shaft connected to an output shaft by at least one first and one second component transmission, arranged parallel to one another in the power flow and each having a frictional power-shift clutch and an intermediate shaft. The intermediate shaft can be operatively connected to the input shaft by the power-shift clutch, with at least one gearbox constant per component transmission. Each gearbox constant has a gearwheel on one of the two intermediate shafts, at least one of which can be operatively connected to a first layshaft arranged parallel to the input shaft. At least one gearbox constant can be brought into an operative connection with the first and the second power-shift clutch.

  • Patent number: 4759432
    Abstract: In a pressure medium adjusting element for actuating a disk clutch; a cylinder is fixedly mounted to a disk carrier and with a shaft segment portion provided with a radial shaft bore for supplying lubricating oil for the clutch; wherein an axial piston operating in the cylinder is connected with a lubricating valve to release a stream of lubricating oil from a large oil retaining baffle chamber, connected with the radial shaft bore, to the disk stack, when the clutch is engaged; and wherein the piston abuts the shaft segment portion and is biased by return springs; and wherein the lubricating valve being structurally disposed in a wall of the baffle and operably connected between the baffle chamber and the clutch chamber containing the disk stack.
