  • Spring damper legs generally consist of a damper tube disposed in a shock absorber and a coil received between an "upper” and a “lower” spring plate under bias coil spring.
  • the shock absorber has an axially movable piston rod, on the free, protruding from the damper tube end of the "upper” spring plate is removably mounted.
  • the lower spring plate is usually fixedly arranged on the damper tube.
  • the upper spring plate of the piston rod can still be provided with a rotatably mounted on a pivot bearing above the upper spring plate mounting plate, via which the spring damper strut is rotatably fastened to the body of a motor vehicle.
  • the support elements each in the form of a gripper claw, which are directly engageable with one of the spring coils of the coil spring into engagement.
  • the two support elements or gripper claws are each inclined towards each other to the longitudinal center axis of the actuator, so that means of this spring compressor, in particular bent in a motor vehicle built-in coil springs can be tensioned.
  • coil springs are not usually part of a spring damper leg.
  • spring tensioners are fundamentally similar built like spring tensioners, which are used especially for the tensioning of coil springs of a spring shock absorber leg.
  • one of the support elements is designed as a gripper claw, which can be brought into engagement with the spring coil of a coil spring arranged in a spring strut.
  • the second support member is formed as a kind of support ring and is placed on the upper spring plate of the spring damper strut for tensioning the coil spring.
  • the bearing surface of this support ring can be adapted to the contour, in particular the pitch of the spring plate.
  • a disadvantage of the constructions described above is that a plurality of interchangeable sets of differently shaped support elements must be provided for clamping differently shaped spring damper legs.
  • the support elements have here holding elements which are fastened via pivotable support arms to a frame.
  • the distance between the holding elements is adjustable transversely to the longitudinal center axis of the respective helical spring on the diameter thereof by pivoting the support arms.
  • the holding elements are hook-shaped and can be hung in one of the spring coils of the coil spring. Since only two retaining hooks are provided, which are to be set in diametrically opposite areas of a spring coil and the respective spring coil can not be fixed otherwise, here despite a certain variability in the adaptation to different sized coil springs the risk of slipping of the retaining hooks.
  • the actuator is designed as a telescopically adjustable length telescopic tube.
  • a support member is fixedly arranged in the upper end of the telescopic tube.
  • This support element forms two pivotable mounting bracket, are arranged at the free ends of each formed as a retaining hook holding elements.
  • the retaining hooks are longitudinally adjustable in longitudinal slots of the support bracket and rotatably received.
  • the second support element is for receiving the Damper tube of the spring damper leg designed as a kind of pipe clamp and arranged stationary on the guide tube.
  • a spring compressor of the generic type for tensioning a coil spring of a Federdämpferbeins which consists of an actuator and two support elements whose distance is variable by an actuation of the actuator.
  • the support members may be fixedly connected to a part of the spring damper leg or the coil spring received under bias in the spring damper leg between a lower and an upper spring seat.
  • this spring compressor as variable as possible for differently dimensioned spring damper legs, one of the support elements on two holding elements which are relative to each other adjustably connected to the actuator.
  • the retaining elements are adjustable in their position and orientation to the geometry of a male spring coil or a male part of the spring damper leg.
  • the holding element can be freely adjusted in their distance from each other and the actuator. Furthermore, the retaining element - within certain limits - designed to pivot about a transverse axis to the spring damper axis, so that an adaptation to the pitch of a male spring coil and / or the surface contour of the upper spring plate is made possible.
  • the holding elements are each mounted on a guide rail, which in turn turn to two are laterally slidably received laterally to the actuator extending support rails.
  • the two support rails are integrally connected to each other and can be given from a horizontal starting position relative to a perpendicular to the actuator pivot axis extending by a predetermined Schenkwinkel.
  • the two guide rails are mounted on parking grooves or openings on the respective support rail and secured by a kind of self-locking in the respective set position.
  • This self-locking is effected by acting on the respective end region of the respective control rail transverse forces, whereby a clamping action between the respective opening and the associated mounting rail is formed.
  • the distance between the holding elements to the actuator is made possible by moving the respective holding element in a guide slot of the associated control rail.
  • the holding elements are secured via sliding blocks in the respective guide slot.
  • the respectively set relative position of the respective holding element to the actuator is effected by tilting the holding elements with their sliding blocks on the adjusting rail at a force on the holding elements.
  • this spring compressor is explicitly on the DE 10 2006 003 284 B3 directed. In operation, it has been shown that the design of this spring compressor in certain "extreme situations" with a certain uncertainty, in particular with respect to the self-locking design of its components is afflicted.
  • the invention is therefore the object of a spring compressor of the generic type safer to design, with a predetermined orientation of the upper spring plate is to be made possible relative to the spring tensioner.
  • the object is achieved according to the invention together with the features of the preamble of claim 1, characterized in that the axial support of the holding elements on the upper spring plate, a pressure plate is provided, which is stationary and / or releasably connected to the holding elements and that the pressure plate with the upper Spring plate is stationary brought into engagement.
  • a variably adjustable spring tensioner can be stabilized in a simple manner if necessary by the two holding elements are fixed against each other on the intended pressure plate. This reliably prevents their spacing and alignment from changing during the tightening process, thereby increasing safety in the application. Since the pressure plate can be brought into engagement with the upper spring plate, slipping or a change in position on the spring plate is also reliably avoided. Also, this pressure plate can be designed such that a certain applications predetermined orientation of the upper spring plate can be adjusted relative to the spring tensioner. For differently designed spring plates and differently designed pressure plates can be provided if necessary, without the spring tensioner itself changes must be made.
  • the pressure plate has a central opening and is releasably connected to the holding elements in each case via screw connections. Due to this configuration, the spring compressor, for example, after DE 10 2006 003 284 B3 retrofitted and remains equally applicable for its normal field of application in an advantageous manner.
  • the pressure plate can also be used for upper spring plate, which have a central, upwardly projecting, dome-like projection. The breakthrough can be adapted in dimensioning the dimensions of this projection, so that the patch pressure plate receives the projection in a form-fitting manner. Slipping or other change in position between the pressure plate and spring plate is thus safely excluded.
  • the central opening of the pressure plate is circular and that a pressure ring is provided which is inserted into the opening of the pressure plate and rotatably and detectably received in the breakthrough.
  • an angular orientation of the spring plate to the spring tensioner also an angular orientation of the spring plate is effected relative to the "remaining" Federdämpferbein so that the spring plate - at least visually - in a simple manner, for example, relative to a provided in the lower end of the damper tube a Federdämpferbeins, transverse bearing eye is alignable.
  • the pressure ring according to claim 4 may have an at least partially encircling, to the pressure plate out projecting bearing web.
  • the pressure plate in the surrounding region of the breakthrough has an angular scale and that the pressure ring is provided with at least one bar marking, which can be aligned by rotating the pressure ring in fürbuch the pressure plate on the angle scale in different angular positions to the printing plate.
  • the pressure ring is precisely aligned in its angular orientation on the pressure plate.
  • the pressure ring or the pressure plate or both the pressure plate and the pressure ring is provided with receiving holes open at the bottom. Is the printing plate itself with provided such receiving bores, so the spring plate with axially upwardly projecting threaded bolt, via which normally takes place the mounting on a motor vehicle body, are brought into engagement with the Duck plate in a predetermined angular position. Due to the rotatable mounting of the pressure ring in the pressure plate, a variable angular orientation of the spring plate to the spring tensioner and thus to the "remaining" spring damper leg is possible in a simple manner. In this case, different pressure rings can be provided with different, adapted to the arrangement of threaded bolts different spring plate arrangement.
  • the pressure plate can be provided with such mounting holes in different arrangements. If the receiving bores of the pressure ring are formed as through-holes, then corresponding retaining screws can be screwed through them into internal threads of the spring plate, which normally serve for fixed mounting of the spring plate on a motor vehicle body.
  • the pressure plate can be designed such that a predetermined angular orientation of the upper spring plate relative to the spring tensioner - at least visually - and thus to the remaining spring damper leg feasible is. Due to the possibly additionally provided pressure ring, the spring tensioner can be adapted on the one hand in a simple manner to differently shaped upper spring plate and on the other hand, the possibility of a variable angle adjustment of the upper spring plate to the spring tensioner and thus the remaining spring shock absorber leg is created.
  • Fig. 1 shows a perspective view of a possible embodiment of a pressure plate 1, via which two retaining elements of a spring compressor are fixedly connected to each other, as will be explained later.

In particular, only one printing plate 1 necessary and a change from a too exciting spring shock absorber leg to a different sized spring damper leg is possible without having to replace the pressure plate 1. For tensioning and relaxing Federdämpferbeinen with different sized spring plates and / or differently arranged threaded bolt thus only different pressure rings 20 are provided to ensure a variable and safe use of a spring compressor 40.
