Abstract
In a suspension strut, the spring support system has a transmission system with a gearbox case and a drive gear that is mounted to rotate in the gearbox case. The adjustment nut, with which the prestressing of the spring can be set, is designed as a gear that works together with the drive gear, by which a rotation of the drive gear produces a screwing motion of the adjustment nut on the thread of the cylinder.
