  • Patent number: 11325439
    Abstract: A height-adjustable spring arrangement for a vehicle includes a bearing spring, a first limiting cylinder with a first limiting cylinder pot and a first limiting piston, a second limiting cylinder with a second limiting cylinder pot and a second limiting piston, and a guide cylinder with a guide cylinder pot, a displaceable guide piston in the guide cylinder pot and a guide piston rod fixed on the guide piston and extending out of the guide cylinder pot along a longitudinal axis of a bearing spring and through the bearing spring. The guide piston rod is displaceable by the first and second limiting cylinders such that a spring preload acting on the bearing spring and a negative spring path of the bearing spring remain constant as a result of a height adjustment.
