Abstract
The invention relates to a integrated motor vane pump hydraulic power unit. A motor rotor (16) and a spindle (15) are assembled into a whole, and are propped on a pump seat (5) and a box body (1) by the aid of a first bearing (14) and a second bearing (18). A high pressure vane pump core (12) is connected with the spindle (15) through a spline (15a), and is arranged in the pump seat (5). A motor stator (17) is assembled on an inner hole (1d) of the box body (1) in a pressing manner. Internal oil of the box body (1) passes through a big oilhole (5a) and a small oilhole (5b) on the pump seat (5), and feeds into an oil-sucking cavity of the high pressure vane pump core (12). An oil-extracting cavity of the high pressure vane pump core (12) is communicated with an oil outlet (7a) of an oil outlet gland (7) to output high-pressure oil. The returning oil of the hydraulic pressure system reflow into the box body (1) via an oil-returning port (22a) through a cooling pipe (21) and an oil-returning pipe (19).
