Embodiment Construction

[0037] As mentioned in the background art, some construction machinery currently needs to add a hydraulic motor when recovering the energy of the hydraulic system. In this way, it is necessary to increase the corresponding system pipelines, thereby increasing the space layout of the main engine and increasing the economic cost. When the hydraulic energy flows in the increased pipeline, a certain energy loss is correspondingly increased, and the maximum utilization of energy cannot be realized.

[0038] In view of the shortcomings in the prior art, the present invention provides a swash plate type hydraulic secondary element, so that the traditional hydraulic plunger pump has the function of a hydraulic motor under the condition of only changing the swash plate variation angle and the valve plate structure. , To realize the conversion between hydraulic plunger pump and hydraulic motor, without additional configuration of hydraulic motor, which not only reduces the economic cost of ...

Abstract

The invention discloses a hydraulic secondary element of a swash plate type. Under the condition of only changing the alteration angle of the swash plate and the structural style of a valve plate, a traditional hydraulic piston pump has the function of a hydraulic motor, which realizes the switch between the hydraulic piston pump and the hydraulic motor without requiring the additional hydraulic motor. Not only has the economic cost of the current energy recovery system been decreased, but the spatial arrangement of a mainframe has been greatly decreased which makes the structure of the mainframe more compact. At the same time, a matching pipeline of the hydraulic system decreases, which achieves the purpose of further reducing the energy consumption. After experiment verification and mainframe test, developed products of the secondary element achieve ideal effects and make a new breakthrough in the traditional hydraulic technology.

Description

Technical field [0001] The invention relates to a hydraulic system, in particular to a swash plate type hydraulic secondary element integrating the functions of a hydraulic pump and a hydraulic motor. Background technique [0002] In the context of environmental pollution and the increasing shortage of traditional energy sources, energy conservation, emission reduction, and energy recovery have always been the focus of technological innovation for construction machinery products. Among them, the hydraulic transmission system gradually replaced the traditional mechanical transmission system with its characteristics of high energy density and high power density, and soon became the main model of the construction machinery industry. Energy-saving research on traditional hydraulic transmission mainly focuses on improving the energy transmission efficiency of hydraulic components and matching with the main engine power system, and has achieved good results. However, traditional energ...
