  • Magnetic piston shoe pair for axial piston pump and motor and control method thereof
    Patent number: 10371130
    Abstract: A magnetic piston shoe pair for an axial piston pump and the motor includes: pistons, coil suites, piston shoes and a swash plate, wherein the interior of the coil suite is a closed coil; the bearing surface that the end surface of the swash plate abuts the piston shoe is provided with micro-molding holes; the micro-molding holes are hemispherical; the back surface of the swash plate is provided with a primary iron core and two secondary iron cores; the iron cores are wound with coil; the coil is connected to an external alternating current power supply. When the pump/motor is working, the coil is energized to generate a magnetic field, thereby adsorbing the piston shoe on the swash plate. Meanwhile, the coil suite generates an inductive magnetic field.
