Torque fluctuation damper
 A device to be connected between the engine and power train of a construction vehicle or the like for damping the fluctuations of the engine output torque. The damper comprises a housing having a drive plate, and a driven plate coaxially mounted in the housing for angular displacement within limits. Mounted between the housing and the driven plate are two friction drive mechanisms for frictionally transmitting the rotation of the housing to the driven plate. A plurality of torsional or compression springs are mounted to the driven plate so as to laterally project out of windows in the housing, so that when a slip occurs in the friction drive mechanisms, the housing acts endwise on the springs to cause their compression. Variable spacings are provided between the ends of the springs and the opposed edges of the housing bounding the windows.
