Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] figure 1 An electrohydraulic motor according to an embodiment of the present invention is schematically shown.

[0025] like figure 1 , 5 As shown, the electro-hydraulic motor includes a housing 1 and a crankshaft 2, and the housing 1 is equipped with a swing plate 3, an oil inlet cylinder 15, an oil discharge cylinder 16, a balance cylinder 17, a reversing valve 4, an oil inlet passage 18 and an oil return passage 19. The oil inlet cylinder 15 , the oil discharge cylinder 16 , and the balance cylinder 17 are respectively connected with reversing valves 4 , and each reversing valve 4 is connected with the oil inlet passage 18 and the oil return passage 19 correspondingly. The reversing valve 4 includes a magnetic induction switch 6 and a magnetic induction sheet 5. The magnetic induction sheet 5 is arranged on the outside of the oil inlet cylinder ...

Abstract

The invention discloses an electrohydraulic motor which comprises a shell and a crankshaft, wherein the crankshaft penetrates through and is mounted on the shell; a swing disk, an oil feeding cylinder, an oil discharging cylinder, a balance cylinder, reversing valves, an oil feeding channel and an oil return channel are mounted in the shell; the oil feeding cylinder, the oil discharging cylinder and the balance cylinder are respectively communicated with the reversing valves; each reversing valve is correspondingly communicated with the oil feeding channel and the oil return channel; the swing disk sleeves the crankshaft; pistons of the oil feeding cylinder, the oil discharging cylinder and the balance cylinder are respectively connected with the swing disk. The electrohydraulic motor has the advantages that oil distribution, clockwise rotation and anticlockwise rotation are easy to control, the operation is convenient, and the cost is lowered.

Description

technical field [0001] The invention belongs to the field of hydraulic motors, in particular to an electro-hydraulic motor with electronically controlled oil distribution. Background technique [0002] Traditional hydraulic motors include gear motors, vane motors, plunger motors, etc. Although the structures of various hydraulic motors are different, the oil distribution mechanisms are basically the same, and they all adopt the oil distribution plate oil distribution structure of plane oil distribution and shaft oil distribution. , but there are oil leakage and wear problems, which affect the hydraulic system performance, life and work reliability of the hydraulic motor. Contents of the invention [0003] The purpose of the present invention is to provide an electro-hydraulic motor, which solves the problems of oil leakage and wear of the oil distribution plate by improving the oil distribution structure of the traditional hydraulic motor. [0004] According to one aspect...
