Embodiment Construction

[0023] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0024] Such as figure 1 As shown, the rotor of the hydraulic pump is the rotor on the vane pump, and the rotor, the stator 3, the upper oil distribution plate 4, and the lower oil distribution plate 5 form a flow-through assembly.

[0025] The rotor consists of a cylindrical rotor body 1 and flat blades 2 . The above-mentioned rotor body 1 is provided with 12 grooves 11 in the radial direction, and the 12 blades 2 are movably inserted into the grooves 11 . During the rotation of the rotor body 1, the vane 2 will protrude radially outward due to the inertia, and press against the stator, between the stator 3, the two vanes 2, the upper oil distribution plate 4 and the lower oil distribution plate 5 A working chamber is fo...

Abstract

The invention provides a hydraulic pump rotor, which belongs to the technical field of hydraulic pumps. It solves the problem that the existing hydraulic pump rotor makes the hydraulic pump generate noise due to flow and pressure pulsation. The rotor of the hydraulic pump includes a cylindrical rotor body and several flat blades, these blades are movably inserted on the rotor body along the radial direction of the rotor body, and the blades are distributed on the rotor body in an unequal manner . The rotor of the hydraulic pump can effectively reduce the flow and pressure pulsation of the hydraulic pump so as to reduce noise and have a simple structure.

Description

technical field [0001] The invention belongs to the technical field of hydraulic pumps and relates to a hydraulic pump rotor. Background technique [0002] With the popularization of automobiles, people have higher and higher requirements for the performance and driving comfort of automobiles, and the reliability, portability and sensitivity of automobile steering are one of them. Therefore, in the steering system of automobiles A hydraulic power steering system is used. [0003] In the prior art, a hydraulic pump includes a rotor, a stator, vanes and an oil distribution plate, wherein the vanes are movably connected to the rotor in an equal division and can freely slide radially, and the rotor is arranged in the stator. During the rotation of the rotor, due to the action of inertial force, the blades always lean on the inner curved surface of the stator, forming a working cavity between the adjacent blades and the left and right oil distribution plates, because the inner s...
