  • this clamping device 140 forms on the one hand a holding device for the damper tube 176 of the spring damper leg 222 and on the other hand, a support member for the lower spring plate 224.
  • this jig 140 replaces a conventional prior art lower looper element, which either with the spring plate 224 or with a lower spring coil of a spring between the two spring plates 221 and 224 recorded under bias coil spring 225 is inserted.
  • clamping device 140 with its mounting section 134 is fixedly arranged on the work surface 135, for example a workbench.
  • This fixed arrangement of the tensioning device 220 ensures extremely easy handling.
  • the special configuration of the clamping device 140 is designed for a "one-hand operation", so that the mechanic a spring shock absorber leg - also in conjunction with the Supporting device 185 - bring in a very simple manner in the jig 140 and fix it there.
  • the clamping device 140 may be performed without the support plate 164, as a vertical alignment of the damper tube 176 ensured by cooperation of the recess 141 and the pressing lever 153 on the one hand and the adjustable support plate 213 on the other hand in a secure manner is.
  • the invention is not limited to the combination option of the clamping device 140 with the clamping device 220 shown in the exemplary embodiment.
  • the clamping device 140 can also be combined with other tools, such as, for example, columnar alignment devices for aligning a spring plate or the like.
  • FIG. 8 can be seen that due to the interaction of the clamping device 140 and the support device 185 is a fully parallel alignment of the spring damper strut 222 with its longitudinal central axis 223 to the actuator 85, so that during the later tightening slipping, in particular of the holding element 39 from a recorded spring coil or from a recorded spring plate 221 is safely excluded.
