Description

Airborne vibration isolation fluid case

Technical field

A kind of airborne fluid tank of relate generally to of the present invention, and relate more specifically to a kind of airborne fluid tank of isolating basically with the vibration that causes by landform and machine.

Background technology

Machine for example track type tractor, wheel type loader, highway and non-road transport truck (on andoff-highway haul trucks), motor-driven grader and other weight equipment is used to carry out many tasks.In order to carry out these tasks effectively, machinery requirement can provide the driving engine of very big torque, in order to drive machines and/or for various hydraulic efficiency pressure systems (for example actuating system, steering swivel system, brake system etc.) power is provided.This driving engine can be diesel motor, engine petrol or dry gas engine, and when machine was motor-driven, this driving engine required to have airborne Fuel Tank.Similarly, because the manoevreability of machine also must load a certain amount of hydraulic fluid and supply actuating system to use on machine.

During machine run, airborne fluid tank (being Fuel Tank and/or hydraulic fluid tank) possibly receive the deflection of external source, vibration, machine and/or fluid tank erecting frame and the infringement in other source, and causes fluid tank to leak or break.Particularly, the high-frequency vibration that is caused by the operation of driving engine or actuating system can pass to fluid tank through the framework of machine.In addition, can be delivered to fluid tank through framework by the draw gear of machine with the machine relevant low-frequency vibration of on rugged landform, going.Possibly not cause the fluid tank material to be passed in time and tired if these vibrations---are not checked---, if or vibration very serious even cause breaking suddenly of Chu Liuxiang.

Authorize United States Patent(USP) No. 4,268,048 (' 048 patent of Teraoka etc. on May 19th, 1981) in the method for attempting to stop the vibration in the trac. fluid tank has been described.Particularly, ' 048 patent discloses the garden tractor of left and right sides wing plate that a kind ofly has seat, is positioned at the change speed gear box at seat rear and is positioned at each cross side of change speed gear box.Pull bar connects left and right sides wing plate so that its minimize vibration.In the space of Fuel Tank between the wing plate of seat rear.This Fuel Tank is connected to the wing plate that is in anterior position through pull bar, and is connected to the change speed gear box that is in the rear position.Total connection between wing plate, pull bar and change speed gear box is used to prevent the vibration in wing plate and the Fuel Tank.

Use although this configuration possibly be suitable for some, it possibly be not suitable for having the more large-scale machine of the induced vibration of higher level.The undeclared any method that is used for vibration that is delivered to Fuel Tank through wing plate or change speed gear box and Fuel Tank isolation of 048 patent particularly, '.Level of vibration in the wing plate of large scale structure and/or earthmoving equipment and the change speed gear box maybe be very high.

In addition, although illustrated fixed configuration possibly be suitable for fluid tank small-sized, symmetric shape in the patent of ' 048, it is not enough to support large-scale or asymmetric fluid case.Particularly because preceding/rear that the fluid tank in the patent of ' 048 only is installed in two places and only is positioned at fluid tank to, shifted laterally only can be limited by minimally with the trend of laterally rotation.That is to say that the large-scale fluid tank with big momentum possibly apply very big power to mounting structure when the machine lateral inclination.Can not resist this power if configuration is installed because of the position is improper, then possibly cause fluid tank to be damaged.In addition, asymmetric fluid case possibly produce non-symmetrical power, and the fabricated section through only two symmetric arrangement is not enough to this non-symmetrical power of supporting.

One or more in the problem that proposes above the purpose of disclosed fluid tank is to overcome.
