  • Control system for an all-wheel clutch
    Patent number: 10065501
    Abstract: A method and a corresponding controller for the four-wheel drive of a motor vehicle are described, consisting of a clutch (AK) disposed in the drive train between a primary axle and a secondary axle (VA, HA) of the four-wheel drive, by means of which the drive torque of a primary axle (KHA, HA) driven by an engine (VKM, SG) can be distributed to a secondary axle (KVA, VA), wherein the controller (S) has a signal connection to the clutch (AK) and to sensors recording the revolution rates of at least one wheel of the primary axle (HA) and one wheel of the secondary axle (VA) and the clutch (AK) is controlled by means of the controller (S) below a specified torque such that a significantly reduced transfer of torque to the secondary axle (VA) is carried out.
    Type: Grant

  • Transfer gear having regulated oil flow
    Patent number: 9523423
    Abstract: The present invention relates to a transfer gear having an input shaft, a first output shaft, a second output shaft, and a torque transmission device which has a clutch in order to distribute a drive torque introduced via the input shaft selectively to the first output shaft and the second output shaft, wherein a drive acts between the torque transmission device and the second output shaft, and wherein an oil reservoir is provided for collecting the lubricating oil.
