Abstract: 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).

Abstract: Provided is a hydrostatic transmission including a pump/motor module having a reservoir housing and a hydraulic pump and motor disposed in the reservoir housing, and a speed reduction module having a speed reduction housing coupled to the reservoir housing and a speed reduction assembly disposed in the speed reduction housing. The speed reduction assembly includes an input member driven by the output shaft of the hydraulic motor, an output member rotationally connected to the input member by one or more belts/chains, and an axle shaft driven by rotation of the output member. By providing the speed reduction assembly in a separate housing from the hydraulic fluid in the reservoir housing, the speed reduction assembly is isolated from the hydraulic fluid thereby preventing particulates from the speed reduction assembly from entering the hydraulic fluid in the reservoir housing.
