Marion Keller 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: 10648514
    Abstract: A structurally and/or functionally improved friction clutch device is disclosed. In particular, a servo spring for a clutch is to be provided which is suitable for series production. In particular, the servo spring is to be realized in the clutch while integrating already existing components. In particular, the servo spring is to keep a maximum disengaging force low. In particular, the servo spring is to operate only under worn conditions; in the new state and during separation it should be possible for it to be force-free. In particular, the total tolerance in the friction clutch device is to remain small, so that the susceptibility of the servo spring force to tolerance deviations is limited.
    Type: Grant

  • Patent number: 9371866
    Abstract: A wet clutch for a motorcycle having an outer basket having a first toothing as the input side of the wet clutch, an inner basket which is coaxial to the outer basket having a second toothing as the output side of the wet clutch, first frictional elements which are torsionally connected to the outer basket, second frictional elements which are torsionally connected to the inner basket, the first and second frictional elements being situated axially alternating between the inner basket and the outer basket, and a clamping element to compress the first and second frictional elements axially in order to produce a torsional connection between the input side and the output side. The inner basket and/or the outer basket can essentially be produced from one or more sheet metal parts.
