Evgenij FRANZ has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11067149
    Abstract: A centrifugal pendulum includes a first flange, a first pendulum mass, and a first preloading element. The first pendulum mass is arranged on the first flange for movement in a radial direction relative to an axis of rotation and relative to the first flange. The first pendulum mass has an innermost point, an outermost point, a radial extension between the innermost point and the outermost point, and a first region arranged radially inward at most five percent (5%) of the radial extension from the outermost point. The first preloading element is arranged to contact the first pendulum mass in the first region for axially preloading the first pendulum mass with respect to the first flange.
    Type: Grant

  • Patent number: 10788098
    Abstract: The invention relates to clutch disc comprising a torsional vibration damper which has an inlet part and an outlet part and a spring device operatively arranged in the peripheral direction between the input part and the output part, wherein the spring device is formed from the first and second spring elements connected behind one another and separated by an intermediate flange, and a centrifugal pendulum which has a pendulum mass carrier arranged about an axis of rotation of the clutch disc and pendulum masses accommodated on same on pendulum paths for oscillation and arranged in a distributed manner over the periphery. In order to improve the insulation effect of the torsional vibration damper and the centrifugal pendulum and/or better adjust same to the required application, the pendulum mass carrier is coupled for conjoint rotation with the intermediate flange and centrally accommodated on the output part.
