摘要： The present invention relates to the field of coal mine underground auxiliary transportation equipment, and particularly relates to an overhead monorail driving unit group realizing mechanical fast power distribution. The overhead monorail driving unit group realizing mechanical fast power distribution includes a rail, wherein the rail is connected with driving portions, carrying trolleys and a hoisting beam, the hoisting beam is disposed in a middle position of the driving portions and the carrying trolleys, and the driving portions, the carrying trolleys and the hoisting beam are connected through driving portion short pull rods, frame-shaped pull rods and driving portion long pull rods. Overhead monorail driving portions have four paths for transmitting a driving force to the hoisting beam, the frame-shaped pull rods directly transmit the driving force of the driving portions in positions far away from the hoisting beam to the hoisting beam, the objective is to reduce an accumulated peak value of the driving force of the driving portion in a mode of serial-parallel arrangement of the overhead monorail driving portions, the problem of horizontal direction bending failure of the rail caused by the driving portions in an operation process of an overhead monorail is solved, and the reliability and adaptability of overhead monorail transportation equipment are improved.

摘要： 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.
