Embodiment Construction

[0015] The preferred technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, a variable-length connecting rod with a hydraulic mechanism of the present invention, in order to prevent engine knocking, produce a larger or smaller compression ratio, that is, to avoid damage to other parts caused by changes in the thrust of the previous push connecting rod, A variable-length connecting rod is provided, which also has a hydraulic buffer function under the instantaneous powerful driving force of the engine piston, and mainly includes a connecting rod 1, and the rod body of the connecting rod 1 is a cavity 2, Cavity 2 leads to connecting rod small end and has piston pipe 3, and piston pipe 3 is provided with piston rod 4, and described piston rod 4 has piston body 5 towards the big end of connecting rod, and piston body 5 moves in cavity 2, so The small head of the connecting ro...

Abstract

The invention discloses a variable length connecting rod with a hydraulic mechanism. The inside of the connecting rod body is a cavity, the cavity leads to a connecting rod small end and has a pistonpipeline, the piston pipeline is internally equipped with a piston rod, a piston body moves in the cavity, the connecting rod small end is internally equipped with a rolling shaft, the rolling shaft has an eccentric pin inside, one roller shaft position facing the piston pipeline is equipped with an arc-shaped sliding chute body, one piston rod end facing the rolling shaft is equipped with a cylindrical pin, the cylindrical pin is located in the sliding chute body, the rolling shaft rotates to drive the piston rod to move, the connecting rod is also internally equipped with a first oil duct and a second oil duct. Compared with the prior art, the variable length connecting rod with a hydraulic mechanism provided by the invention has the characteristics of simple structure and high feasibility, realizes two-stage variable high-low compression ratio, not only can improve the partial load thermal efficiency of a gasoline engine, but also can avoid detonation under a heavy load, and effectively improves the reliability and economical efficiency of the engine.

Description

technical field [0001] The invention relates to a connecting rod, in particular to a variable-length connecting rod with a hydraulic mechanism, and belongs to the technical field of engine moving parts. Background technique [0002] Generally, existing internal combustion engines have four strokes of suction, compression, work, and exhaust. The air passes through the piston to complete the suction and compression strokes, and its volume is compressed several times to dozens of times and mixed with fuel. After the explosion, its volume will expand dozens of times on the original basis, so that the expanded gas pushes the piston to do work. Because the piston of general existing internal-combustion engine is all equal strokes in suction, work, exhaust, compression working stroke, the air pressure that its expansion gas produces can only have a part to be used for doing work, and the rest is exhausted by muffler, exhaust. The trachea, etc. are consumed, and then discharged; th...
