  • Patent number: 11661974
    Abstract: A torque-transmitting apparatus for a drive assembly includes: a first coupling device for transmitting torque and compensating a shaft offset, and a second coupling device for transmitting and limiting torque, the first and second coupling devices being connected in series. The second coupling device includes an inner hollow part and an outer hollow part. The inner hollow part radially outwardly includes a first frictional surface and the outer hollow part radially inwardly includes a second frictional surface, which is connected to the first frictional surface and interacts therewith. The inner hollow part includes a fillable pressure chamber.
    Type: Grant

  • Patent number: 10400860
    Abstract: A transmission arrangement with a first rotatably mounted drive-side shaft paired with a first drive toothing; a second rotatably mounted drive-side side shaft paired with a second drive toothing; a rotatably mounted ouput-side shaft paired with an output toothing; a first number of first planet shafts, each of the first planet shafts being paired with a first planet toothing and a third planet toothing; and a second number of second planet shafts, each being paired with a second planet toothing and a fourth planet toothing. The first drive-side shaft and the second drive-side shaft are coaxially relative to each other; the first planet toothing engaged with the first drive toothing; the second planet toothing engaged with the second drive toothing; and the third planet toothing and the fourth planet toothing are engaged with the output toothing.
