A spring compressor for large coil springs especially for motor vehicle axle springs comprises first and second disc-like pressure plates which are located at spaced locations along the axis of a cylindrical guide tube and each has a central bore opening. A threaded spindle has a spindle head with a key profile and it is rotatably mounted in an axial thrust bearing of the cylindrical guide tube. The guide tube has a radial support surface on which one of the pressure plates is supported. A cylindrical threaded tube has internal threads insertedly engaged with the threaded spindle and the spindle is connected to the guide tube with an axial mobility so as to rotate with the guide tube. The threaded tube has an end which faces away from the spindle head which has a plurality of radial fingers which fit into corresponding recesses formed in the first pressure plate which includes radial enlargements which form passages for the radial fingers carried by the threaded tube. The fingers of the threaded tube are at least three in number and are substantially wedge-shaped radially extending fingers which taper in a direction away from the spindle head and they engage in a corresponding number of recesses of the second pressure plate. The pressure plate is also provided with enlargements between every two recesses and are countersunk on the exterior of the pressure plate and have diagonal faces shaped so that no planar support surface is present for the fingers outside of the recesses. |
