Abstract

Die Erfindung betrifft eine Vorrichtung (21) zum Spannen eines Federdämpferbeines (29) mit wenigstens einem Greiferelement (20), welches beim Spannvorgang mit einer Federwindung (22) einer im Federdämpferbein (29) zwischen einem oberen und einem unteren Federteller (60 und 63) unter Vorspannung eingesetzten Schraubenfeder (23) in Eingriff steht und mit einem Kupplungselement (64), welches mit einem von der ersten Federwindung axial beabstandeten Teil, insbesondere mit dem unteren Federteller (63) des Federdämpferbeins (29) in Eingriff steht, wobei zum Spannen der Schraubenfeder (23) der axiale Abstand zwischen dem Greiferelement (20) und dem Kupplungselement (64) veränderbar ist und, wobei das Federdämpferbein (29) eine Kolbenstange (28) aufweist, welche mit einem radial vorstehenden Teil (Teller 27) versehen ist. Erfindungsgemäß ist im Bereich des Greiferelements (20) ein Haltelement (1, 40, 50) vorgesehen, welches aus einer neutralen, nicht mit dem Teil der Kolbenstange (28) in Eingriff stehenden Position in eine wirksame, mit dem Teil (Teller 27) der Kolbenstange (28) in Eingriff bringbar Position verstellbar ist.

The invention relates to a device (21) for tensioning a spring shock absorber leg (29) with at least one gripper element (20) which, during the tensioning operation, has a spring turn (22) in the spring shock absorber leg (29) between an upper and a lower spring plate (60 and 63). biased coil spring (23) is engaged and with a coupling element (64) which is in engagement with a part axially spaced from the first spring coil part, in particular with the lower spring plate (63) of the spring damper leg (29), wherein for clamping the Coil spring (23), the axial distance between the gripper element (20) and the coupling element (64) is variable and, wherein the spring damper strut (29) has a piston rod (28) which is provided with a radially projecting part (plate 27). According to the invention a holding element (1, 40, 50) is provided in the region of the gripper element (20), which consists of a neutral, not with the part of the piston rod (28) engaged position in an effective, with the part (plate 27) of Piston rod (28) engageable position is adjustable.
