Abstract

Disclosed is a hydrostatic rotary piston machine according to the orbit principle, having a power element (51) acting as an output and comprising a stationary stator (52), a rotary piston (8), and a rotatably mounted shaft (11), wherein the rotary piston (8) is disposed eccentric to the shaft (11) for carrying out an orbit motion. The rotary motion of the rotary piston (8) and the shaft (11) is generated in that toothed chambers (8) formed between the stator (52) and the rotary piston (8) are supplied with and disposed of working fluid (6) by means of a rotary valve (3). According to the invention, the volume of the toothed chambers (8) and thus the displacement of the rotary piston machine is variable. To this end, the rotary piston (8) is axially displaceable relative to the stator (52) by means of adjusting elements (22). The toothed chambers (6) are axially sealed in the axial direction by an axially fixed rotary piston plate (17) radially coupled to the rotary piston (8), and by a stator plate (14) axially coupled to the rotary piston (8) and radially decoupled from the rotary piston (8), wherein the volume of the toothed chambers (6) is continuously variable by axially displacing the rotary piston (8) and the stator plate (14) by means of the adjusting elements (22). The variable displacement allows both economical operation as a motor, because the displacement adapts to the instantaneous power and torque demand and hydraulic losses can thereby be reduced, and operation as a pump for recuperative utilization of braking energy, because cavitation can be prevented by adapting the displacement as a function of the speed in pump mode. The rotary piston machine is thus suitable as a wheel motor for direct hydraulic drive of a vehicle having braking energy recovery.
