  • Patent number: 8636113
    Abstract: A shaft arrangement having a shaft and at least one component, which is arranged on the shaft and which is to be lubricated and/or cooled by a fluid. A fluid feed device being designed to feed the fluid to the shaft arrangement radially from outside. The component is a shaft sealing ring, which rests on the shaft and which is fixed to a housing. A baffle plate, which with the shaft sealing ring defines a fluid baffle chamber and which is separated by an annular gap from the outer circumference of the shaft, is arranged axially next to the shaft sealing ring. The fluid feed device is arranged so that fluid is fed into the fluid baffle chamber.

  • Patent number: 8056442
    Abstract: An all-wheel drivetrain for a motor vehicle, which has at least two driven axles, comprising a characteristic torque converter transmission of longitudinal construction. To the input side of the transmission drive power is fed and the transmission serves for converting a characteristic of a drive engine. The output side of the transmission is connected to a transfer device, by means of which the drive power can be distributed to the two axles. The transmission has an output shaft which is connected to a first drive shaft for the first axle, and a countershaft parallel thereto. The output shaft and the countershaft are connected to one another by means of a first constant transmission ratio. The countershaft is connected by means of a second constant transmission ratio to a second drive shaft for the second axle. The transfer device is arranged coaxially with the second drive shaft.
