  • Patent number: 11761513
    Abstract: A crankshaft arrangement for an internal combustion engine includes a crankshaft, a torsional vibration damper having a primary mass and a flywheel, wherein the primary mass is connected fixedly to the crankshaft, and the flywheel and the primary mass are coupled via a viscous fluid. The torsional vibration damper is attached to an output end of the crankshaft. The primary mass is coupled to a secondary coupling via an elastomer coupling ring. The torsional vibration damper is coupled to the secondary coupling via a feedback device. The feedback device has a negative stiffness.
    Type: Grant

  • Publication number: 20230182522
    Abstract: A spring system of a vehicle, in particular a utility vehicle, includes a first spring/damper unit with a first stiffness and a first damping; a second spring/damper unit with a second stiffness and a second damping; and an additional mass as a tuned-mass absorber. The tuned-mass absorber is coupled to at least one negative stiffness. A vehicle having such a spring system and a method for adapting the stiffness of a spring system are provided.
