Abstract

The invention relates to an assembly for providing constant oil suction pressure for a hydraulic pump. A hydraulic pump is a vehicle-mounted hydraulic system hydraulic pump, wherein the assembly comprises a liquid medium storage device (2), a liquid medium input pipeline and a liquid medium output pipelines, wherein the liquid medium input pipeline and the liquid medium output pipelines connectedwith the storage device (2), the assembly is characterized in that the number of the medium input pipeline is 1, and the number of the medium output pipelines is 2; and the storage device (2) is a sealed storage device (2) of which the longitudinal section is in a convex shape and is internally provided with a longitudinal piston (3). According to the technical scheme, the structure is simple, theuse is convenient, and the assembly is capable of resisting vibration and impact.

Description

technical field [0001] The invention relates to the field of hydraulic systems, in particular to a component that provides constant oil suction pressure for a hydraulic pump. Background technique [0002] The hydraulic system has the advantages of high power / mass ratio, large output force and good compliance, so it is widely used in robots and construction machinery, such as robot joint drive, and construction machinery such as excavators and loaders. These devices usually have higher requirements in terms of small size, light weight and compact structure. [0003] The hydraulic system of the legged robot adopts a positive pressure closed circuit design. In the closed hydraulic system, the oil output by the hydraulic pump directly enters the actuator, and the return oil of the actuator is directly connected to the oil suction pipe of the hydraulic pump. The working fluid in the system Closed circulation in the pipeline. Its structure is compact, and there are few chances o...
