[0004] The fixed swash plate axial piston pump adopts the transmission method that the main shaft drives the cylinder body to rotate through the spline, and the flow distribution plate is used on the bottom end of the cylinder body to distribute the flow; the traditional fixed swash plate axial piston pump has cylinder body-distribution plate, Sliding shoe-swash plate, plunger-plunger hole have many pairs of high-speed friction pairs, especially the cylinder body-distribution plate friction pair, which is more easily damaged by the overturning moment of the cylinder body and has low working reliability
Moreover, there are many rotating parts, the structure is complex, and the volume is large.

The present invention relates to a swash plate driven flow distribution integrated plunger pump, comprising a main shaft, a cylinder body, a front housing, a swash plate, a plunger, a sliding shoe and a return assembly, the swash plate is rotatably arranged in the front housing, and the cylinder body and The opposite end surface of the swash plate is provided with a plunger hole, and the plunger is slidably fitted with the plunger hole. The sliding shoe is arranged in the return component, and the return component is provided with an oil hole, and one end of the center hole of the plunger is connected with the oil hole. The other end of the center hole of the plunger communicates with the plunger hole on the cylinder body, the return component fits the slope of the swash plate, the end surface of the swash plate is provided with a high-pressure oil chamber and a low-pressure oil chamber, and the outer surface of the front housing An oil inlet and an oil outlet are provided, and the oil outlet is connected with the high-pressure oil chamber. There is a spindle center hole in the main shaft, and a radial hole is arranged on the side of the main shaft. The low-pressure oil chambers are connected, the invention has low starting torque and friction torque, high power density and reliability, and the invention relates to the technical field of axial piston pumps.
Description
Technical field [0001] The present invention relates to the field of axial piston pump technology, more particularly, to a swashplate drive distribution integrated plunger pump. Background [0002] Swashplate axial piston pump is a commonly used hydraulic component in the hydraulic transmission system, because of its compact structure, compared to other hydraulic pumps with high pressure, long life and other outstanding advantages, has been widely used. [0003] Swashplate axial piston pump can be roughly divided into two types: fixed swashplate axial piston pump and rotary swashplate axial piston pump from the structure. [0004] Fixed swashplate axial piston pump adopts the transmission mode of spindle driving the cylinder body rotation through the spline, and distributes the flow with the distribution disc on the bottom end of the cylinder block; the traditional fixed swashplate axial piston pump has a cylinder body - distribution disc, sliding shoe - swash plate, plunger - pl...
