FIELD: hydraulic engineering. SUBSTANCE: hydraulic system has main and additional hydraulic loops and pump with the outlet shaft. The shaft is kinematically coupled with a drive engine trough clutch and gear box. The clutch consists of two hollow bushings. One of the bushing is inserted into another one. The bushing, which has inner slots, is coupled with the shaft of the pump. Outer toothing of the bushing engages with inner toothing of the other one. The bushing is set in a bearing within the housing of the gear box and in the bore of the take-off shaft. The additional loop is connected to one of the sections of a hydraulic distributor. EFFECT: improved design. 2 dwg
