摘要

The spring has a support bearing (2) and a support (3), which are connected to each other by a cone-shaped spring (4). A height adjustment device (5) is assigned to the bearing and/or support, for height adjustment of the spring, where the adjustment device is hydraulically and/or pneumatically adjustable. The adjustment device is connected with an energy storage (7) that is fillable by vibrations in driving operation. The adjustment device includes a measuring device for distance measurement, where the height adjustment of the spring is performed depending on the measured distance.
