By pressurising one of the pressure ports (5/6) the operation medium gets into the steering zone (7/8) of themotor. Depending on port (5/6) and therefore on the pressurized steering zone (7/8), the rotation direction of themotor will change. Due to the steering unit (7/8), high pressurized operation fluid gets to the pistons (1) and forces them to extend against the wobble plate (2). Because of the draft angle of the wobble plate (2), the piston load results by resolution of a force and lever arm into a torsional moment. During rotation movement the fixed with the shaft (3) mounted eccentric (11) and its steering discs (9) overtravels the different pilot holes (12) which occurs in a continuous opening and closing. The pistons fully extend based on the draft angle of the wobble plate, then they are forced by the new high pressure to run back into the drive case (4). This effect causes the now low pressurized operation medium to flow via the other pressure port (5/6) back to the HPU's (Hydraulic Power Unit) tank. Functional descriptionwobble plate The wobble plate (2) is fixed to the drive shaft (3) mounted plate with a certain draft angel. By feeding the motor with operation medium, the parallel to the drive shaft arranged pistons (1) start to fulfill an axial load which forces the wobble plate (2) and therefore the pivoted drive shaft (3) to turn. Functional description of these axial pistonmotors All mentioned hydraulic motors in this catalogue are designed with a fixed displacement and work according to the wobble plate principle. The purpose of a hydraulic drive is to transfer hydraulic power in to mechanical power. Hydraulic power is created by the hydraulic volume flow as well as the pressure difference which is pending between the motors inlet and outlet. The mechanical power results from the speed, torque and efficiency of the motor which can be directly applied from the drive shaft. The required pressure difference in order to turn the shaft will automatically adjust itself to the needed torque at the drive shaft specified by the application. Therefore the needed pressure difference will always be load-dependent. The engine speed on the other hand is directly controlled by the feed of the volume flow of the hydraulic pump.
