ABSTRACT:
A spring cramp for large helical springs, particularly axle springs of motor vehicles, comprises two loose disc-shaped pressure plates having annular contact surfaces serving as abutments for the spring turns and provided each with a central hole, a threaded spindle, and a threaded tube. The threaded spindle is mounted by means of an axial bearing for rotary motion and concentrically in a guide tube on which a shoulder is provided near the head of the spindle, which shoulder is formed with two lug elements for securing a lower one of the pressure plates at the side of the spindle head against rotation. The threaded tube which is threadable onto the spindle may be advantageously telecopically inserted into the guide tube. The threaded tube and the guide tube are non-rotatably connected to each other by two slot-and-feather connections. The threaded tube can be connected non-rotatably, in the direction of axial tension, to the other pressure plate, so that during the compression of a spring, the two plates are secured against mutual rotation.
