| 摘要 |
The invention relates to a drive train (1) for a hydraulic drive where a friction coupling (3) is arranged between a hydraulic machine (2) and a consumer (5). The coupling (3) has two parts (20A, 20B) which are displaceable towards each other in the axial direction (18) and are connected to the hydraulic machine (2) or to the consumer (5). Hydraulic fluid is introduced by means of a pressure line (28) into a pressure chamber (27) formed between the parts (20A, 20B), as a result of which the complementarily formed friction surfaces (9A, 9B) become frictionally locked together and a torque is able to be transmitted between the hydraulic machine (2) and the consumer (5). The friction surfaces (9A, 9B) are each fixedly connected at least radially to the shaft of the hydraulic machine (2) or of the consumer (5).
