  • Patent number: 11833877
    Abstract: A spring damper apparatus for a vehicle, with a hydropneumatic system, via which a wheel of the vehicle can be braced spring-mounted and damped on a body of the vehicle. The hydropneumatic system includes a first chamber delimited at least partially by a partition element, in which a fluid acting on the partition element is accommodated. In addition, the hydropneumatic system includes a second chamber separated from the first chamber by the partition element and delimited by the partition element, in which a gas forming a gas spring and acting on the partition element is accommodated. In addition, the hydropneumatic system includes a housing in which the fluid is accommodated. In addition, the hydropneumatic system includes a piston shiftably accommodated in the housing and acting on the fluid, via which piston the wheel can be braced on the body.
