Geluote energy saving high efficiency hydraulic deflector

Abstract

The present invention relates to a Groth's energy-saving high-effective hydraulic steering equipment, belonging to the field of hydraulic transmission technology. Said steering equipment is composed of the following several portions: external shell, flow channel communicated with fluid inlet and fluid outlet, valve body and valve core, universal driving shaft, spline gear pair, cycloid gear pair, rotor and non-return valve, etc. Said invention also provides the connection mode of all the above-mentioned portion and the working principle and operation method of said steering equipment.

Description

technical field [0001] The invention relates to a mechanical energy-hydraulic energy conversion control device, in particular to an improved flow channel structure of an energy-saving and high-efficiency hydraulic steering gear, belonging to the technical field of hydraulic transmission. Background technique [0002] The hydraulic steering gear is a common hydraulic transmission device that realizes the conversion control of mechanical energy to hydraulic energy. Its core components are the curved pin wheel meshing pair and the rotary valve flow distribution mechanism. The function of the curved needle wheel meshing pair is to realize the metering of the hydraulic flow, and the function of the rotary valve is to control the direction of the liquid flow. The structure of a typical steering gear can be found in figure 1 , the valve body 1 is fixedly connected with the stator 9 and the rear cover 25 through the partition plate 8, and a flow channel communicating with the liqui...

Problems solved by technology

[0004] However, the applicant found in the long-term practice research that there are still deficiencies in the existing hydraulic steering gear: first, when the steering is not required, the pressure liquid must completely pass through the flow channel with a large damping in the valve body, and still has certain energy. consumption

Secondly, in addition to the relatively complex flow channel structure in the valve body, there are many external joints and interfaces, so the volume is relatively large, and it is difficult to meet the requirements of miniaturization.

In addition, the valve sleeve and the valve body are easily deformed during the working process, which hinders the rotation of the valve sleeve and affects the stability of performance.
