The Figure shows the design drawing of a disc set. In a, the pressure oil is inserted through a bushing into the shaft and passes through transverse holes in the space of the pressure cylinder d. The two friction plates b and c, torque proof splined sleeve h but movable are connected, are turnable on the shaft . This rotation of the pulley on the shaft takes place but only to the extent that run up the balls of the pressing device on the sloping curved paths. The pressing device, which is located entirely in the oil chamber of the cylinder is here from the shaft-side cam carrier g and the disk-side cam carrier e. Instead of the balls are rolling here as f roll off frame switched between. Such a pressing device with curved paths that include the pane stroke, has a rotation game that will change the direction of the torque from the right edge of the curved path through the left flank. Such games are turning into unwanted mechanical power transmissions, torque shocks because they have to follow. Therefore, the disk set has a hydraulic shock absorber in the form of a tow valve j. The disc-side cam carrier is mounted on an e splines of the disc and the neck is pushed axially by a spring i in the direction of the shaft-side cam carrier g. At the zero crossing of the torque curve of the disk-side carrier is moved forward by the spring altogether, and the rolls come in the basic curve. When the torque increases, the wheels run on the two oblique F Lanken highly curved paths and push back the disk side cam carrier to the action of the spring force until he sits up on the glass plate c. This placement does not happen with a shock, because this displacement process that developed in the form of a piston ring up to a tow valve j k linen gap closes, and evaporate the hydraulic movement
