Double-power engine with adjustable hydraulic and mechanical power output ratio

Abstract

The invention belongs to the technical field of internal combustion engines, and relates to a double-power engine with an adjustable hydraulic and mechanical power output ratio. A piston is connected with a connecting rod through a piston pin, the connecting rod is fixedly connected with a sliding block groove through a fastener, a sliding block is embedded in the sliding block groove, the lower portion of the sliding block groove is provided with a plunger and a guide rod, and the plunger, the guide rod and the sliding block groove move synchronically. The guide rod is inserted into a guide hole in a pump support and guides movement of the plunger. The connecting rod, the sliding block groove and the plunger move up and down in a reciprocating mode. A crank pin is embedded in the sliding block, and the upper portion of a plunger sleeve and the upper portion of the pump support are provided with oil inlet holes in a communication mode. A plunger stroke adjusting rack is parallel to a crank and arranged on one side of a hydraulic plunger pump. A rack support fixes the plunger stroke adjusting rack on the pump support, and the plunger stroke adjusting rack is meshed with a gear ring of the plunger sleeve. The double-power engine is simple in structure, reliable in principle, high in energy efficiency, cost-saving, fast in power transmission and environment-friendly.

Description

Technical field: [0001] The invention belongs to the technical field of internal combustion engines, and relates to a device for mutual conversion of various energies, in particular to a dual-power engine with adjustable output ratio of hydraulic pressure and mechanical power. Background technique: [0002] Construction machinery requires hydraulic and mechanical power at the same time, but traditional engines cannot output both hydraulic and mechanical power at the same time. Poor stability, single output power, only hydraulic power, it is difficult to be directly and rationally used in the demand hydraulic and mechanical dual power machinery; although other similar types of engines can solve the problem of unfixed top dead center and poor ignition stability of free piston engines problem, but it is difficult to satisfy the situation of hydraulic and mechanical dual power demands at the same time. Therefore, seeking to design an engine that uses hydraulic and mechanical po...
