  • Patent number: 11560855
    Abstract: A flap device for a motor vehicle comprises a flap housing that can be flowed through by a gas flow; and a flap shaft that is rotatably supported about an axis of rotation in the flap housing by means of at least a first and a second bearing element, which are held at the flap housing, and that carries a flap for selectively blocking or throttling the gas flow. The flap shaft is supported at the first bearing element in a first axial direction via a fixed abutment element that is axially fixedly arranged with respect to the flap shaft.

  • Patent number: 11220982
    Abstract: The invention relates to a flap device for controlling a gas flow through a pipe, in particular to an exhaust gas flap device for an exhaust train of a motor vehicle, comprising at least one flap which is arranged in a flap housing, in particular in a tubular flap housing, rotatable, in particular rotatable by a drive unit, about an axis of rotation of a flap shaft between an open position and a closed position, with a spring means being provided which, on a rotation of the flap from the open position into the closed position, tangentially and/or radially elastically loads the flap shaft at the latest in the closed position of the flap, and with at least one section of the spring means being directly or indirectly rotationally fixedly connected to the flap housing with respect to a rotation about the axis of rotation.

  • Publication number: 20190032607
    Abstract: A flap device for controlling a gas flow through a pipe comprises a flap that is rotationally fixedly connected to a flap shaft and at least one support unit by means of which the flap shaft is rotatably supported. A radial hollow space that is bounded in an axial direction by respective attachment surfaces is formed between the flap shaft and a reception section of the support unit. A damping element composed of an elastic material is clamped in the hollow space with axial and/or radial deformation and/or preload.
