Internal combustion hydraulic compound drive engine

Abstract

The invention relates to an internal combustion hydraulic combination driving engine which comprises a hydraulic oil tank, a first internal combustion cylinder, a second internal combustion cylinder, a first hydraulic oil cylinder and a second hydraulic oil cylinder. The internal combustion cylinders and the hydraulic oil cylinders are provided with bi-directional pistons. Internal combustion cylinder covers and hydraulic oil cylinder covers are arranged on one side of the hydraulic oil tank, and a first internal combustion-hydraulic cylinder cover and a second internal combustion-hydraulic cylinder cover are arranged on the other side of the hydraulic oil tank. A main lever is connected with an air inlet / exhaust mechanism through an auxiliary lever. Piston rods of the two internal combustion cylinders and on the internal combustion cylinder covers are connected through the main lever. Piston rods of the two hydraulic oil cylinders and on the hydraulic oil cylinder covers are connected through the main lever. Internal combustion cylinder piston rods on the internal combustion-hydraulic cylinder covers are connected with the piston rods of the hydraulic oil cylinders through the main lever. The internal combustion hydraulic combination driving engine formed by the internal combustion cylinders and the hydraulic oil cylinders saves fuel, is less in discharged harmful gas, simple in structure, small in mechanical friction and low in production and use cost, increases output power and improves use performance.

Description

technical field [0001] The invention belongs to the technical field of power and hydraulic pressure, relates to an internal combustion and hydraulic engine, in particular to an internal combustion hydraulic compound drive engine. Background technique [0002] At present, the engines used in various construction machinery are crank-connecting-rod piston internal combustion engines. The power transmission system is to convert the heat energy of the fuel into the reciprocating linear mechanical power of the piston through the piston-type internal combustion engine, and then convert the reciprocating linear mechanical power of the piston through the crank-connecting rod mechanism. The mechanical power conversion output is the rotary mechanical power, and the final conversion output is the power mode required by the application system. Although this type of energy combined power transmission system realizes the energy demand of converting heat energy into output, due to the long ...

AI Technical Summary

Problems solved by technology

Although this type of energy combined power transmission system has realized the energy demand of converting heat energy into output, due to the long energy conversion and transmission route in the system, not only the mechanical efficiency is lost, but also serious wear and tear occurs between the piston and the cylinder wall, the plunger and the sliding sleeve. additional heat load

At the same time, the stress strength of the crank-link mechanism is high, and the friction loss at each hinge point is serious, resulting in problems such as low conversion and transmission efficiency, serious energy waste, complex and heavy transmission system, high production and operation costs, and serious pollution.
