Embodiment Construction

[0037] As mentioned in the background technology section, some construction machinery currently need to add hydraulic motors when recovering energy from the hydraulic system, which relatively increases the matching system pipelines, thereby enlarging the space layout of the main engine and increasing the economic cost. When the hydraulic energy flows in the increased pipeline, a certain amount of energy loss is correspondingly increased, and the maximum utilization of energy cannot be realized.

[0038] Aiming at the deficiencies 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 angle of the swash plate and the structural form of the distribution plate. , realize the conversion of hydraulic plunger pump and hydraulic motor, without additional hydraulic motor, which not only reduces the economic cost of the c...

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 which integrates the functions of a hydraulic pump and a hydraulic motor. Background technique [0002] Against the backdrop of environmental pollution and increasing tension in traditional energy sources, energy conservation, emission reduction, and energy recovery have always been the focus of technological innovation in construction machinery products. Among them, the hydraulic transmission system has gradually replaced the traditional mechanical transmission system due to its high energy density and high power density, and soon became the main model in the construction machinery industry. Energy-saving research on traditional hydraulic transmission mainly focuses on improving the energy transfer efficiency of hydraulic components and matching with the main engine power system, and has achieved good results. However, the traditional research...
