  • Patent number: 9987914
    Abstract: The invention relates to a method for operating a ground-coupling arrangement for a vehicle comprising a ground receiving element for receiving a grounding object, wherein the ground receiving element is at least partially filled with a fluid which contacts the grounding object; at least one coupling means which is designed for coupling the grounding object to the ground receiving element by means of the fluid and thus to a vehicle structure that is rigidly connected to the vehicle, and/or for at least partially decoupling of the ground receiving element from the vehicle structure; and a hydraulic line which connects the coupling means to the fluid, wherein the grounding object compresses the fluid in the case of a crash and the coupling means directs the fluid out of the ground receiving element or reroutes the fluid in the ground receiving element.
