Abstract
The utility model discloses a connecting pull rod, which comprises an aluminum bracket, wherein the aluminum bracket comprises a rod body, a large outer ring hole end and a small outer ring hole end, wherein the large outer ring hole end and the small outer ring hole end are arranged at the two ends of the rod body; the large outer ring hole end is provided with a large outer ring; a large bush is arranged in the large outer ring and comprises a large tube rubber body and a large inner tube which is arranged in the large tube rubber body and is eccentric with the large outer ring; the large tube rubber body, the large outer ring and the large inner tube are vulcanized into a whole; a small bush is arranged in the small outer ring hole end and comprises a small tube rubber body and a small inner tube which is arranged in the small tube rubber body; and the small tube rubber body and the small inner tube are vulcanized into a whole. According to the connecting pull rod provided by the utility model, the problems of poor vibration reduction effect and high probability of producing noise of the anti-vibration pull rod during high-frequency vibration of an engine are effectively solved, and the NVH (Noise Vibration and Harshness) performance of an entire vehicle is improved.
Description
Technical field
The utility model relates to a kind of support part that is used to support driving engine, relates in particular to a kind of cylinder lever connecting rod.
Background technology
Chinese patent CN2725075 discloses the soft cushion structure that suspends behind a kind of automotive engine; It is to insert and put yielding rubber by upper and lower clamping plate to constitute; Yielding rubber wherein adheres between the upper and lower clamping plate, and lower plate is provided with soft cushion structure is fixed in two bolts on the car body, and the train wheel bridge top is installed with the dihedral plate; Be installed with two bolts on one inclined-plane of this dihedral plate; This bolt is connected fixing with automotive engine, the distolateral of upper and lower clamping plate bends inwards, and suspends soft cushion structure behind this automotive engine when normal operating condition; The inclined-plane of dihedral plate bolt of rear end plate is to be the level of state, and the long side relative with the stationary engine bolt of lower plate bends inwards and be resisted against on the yielding rubber.But the oscillation damping pull rod of this structure is when the driving engine high-frequency vibration, and bolt is loosening easily, causes noise, influences the NVH performance of car load.
Summary of the invention
The utility model mainly is to solve the technical matters that existing in prior technology oscillation damping pull rod effectiveness in vibration suppression when the driving engine high-frequency vibration is not good, be prone to produce noise etc.; A kind of cylinder lever connecting rod is provided; Efficiently solve the problem that oscillation damping pull rod effectiveness in vibration suppression when the driving engine high-frequency vibration is not good, be prone to produce noise, improved the NVH performance of car load.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals: it comprises aluminum frame; Big outer shroud nose end and little outer shroud nose end that said aluminum frame comprises shaft and is located at said shaft two ends; Said big outer shroud nose end is provided with big outer shroud; Be provided with Large lining in the said big outer shroud; Said Large lining comprise the bassoon rubber bodies be located in the said bassoon rubber bodies and with big outer shroud accentric imperial palace pipe, said bassoon rubber bodies is sulfided into one with big outer shroud, imperial palace pipe, is provided with little lining in the said little outer shroud nose end; Said little lining comprises the tubule rubber bodies and is located at little interior pipe in the said tubule rubber bodies that said tubule rubber bodies and little interior pipe are sulfided into one.The utility model is used for driving engine and carriage junction, stationary engine position; The utility model adopts shears the shape vibration-proof structure, can bear harsh shearing force; The utility model utilizes the rubber internal friction characteristic, up-and-down movement before and after the driving engine is become rub motion, thereby reach the vibration damping purpose.
As preferably, the said bassoon rubber bodies that is positioned at said imperial palace pipe both sides is provided with cushion hole.
As preferably, said shaft is provided with the bar hole.
As preferably, the axis parallel of the axial line of said big outer shroud and said imperial palace pipe.
As preferably, the axis parallel of the axial line of said big outer shroud and said little outer shroud nose end.
As preferably, the axial line of said little outer shroud nose end with said little in the axial line of pipe overlap.
The beneficial effect that the utility model brings is, efficiently solves the problem that oscillation damping pull rod effectiveness in vibration suppression when the driving engine high-frequency vibration is not good, be prone to produce noise, improved the NVH performance of car load.
