Rectangle base station is additionally provided with fuel oil bottom half, damping dress is additionally provided between rectangle base station and fuel oil casing
Put.Further, a rectangle base station is also set up in fuel oil bottom half, can plays a part of supporting fuel oil casing, damping dress
Fuel oil casing can effectively be reduced to the vibration transmission between vehicle body by putting, and further reduced vibrated rock of fuel oil casing and produced oily rolling
The problem of noise.
It is preferred that, the damping device includes damping straight tube, damping spring and support straight tube, one end of the damping straight tube
Fixed with fuel oil casing lower surface, the other end is provided with the end face of a through hole and tube wall edge and damping spring and fixed, the branch
Support one end of straight tube and the upper surface of rectangle base station is fixed, the other end passes through damping spring and is placed in damping straight tube and carries through hole
In end face.
The supporting plate is 8~10mm in the thickness that fuel pipe points to fuel oil casing direction.Further, fuel oil pipe connector
Length be usually 3~5cm, the thickness of supporting plate is arranged between 8~10mm, can save material in the case of ensure peace
Spring is installed between fuel pipe with vibration damping.
The present invention compared with prior art, has the following advantages and advantages：
1st, the fuel oil tube assembly of a kind of high stability of the invention, a supporting plate is provided with the side of fuel oil casing, is made
Fuel pipe is securely screwed together with through hole, the sealing on the outside of fuel oil pipe connector is ensure that with this, it is to avoid fuel pipe
Oil leak, is solved because of fuel oil pipe connector leakage, air enters in fuel tank body, and the empty liquor ratio in increase fuel tank body is increased
The impulsive force of liquid knockout fuel oil casing so that the problem of noise increase in fuel tank；
2nd, the fuel oil tube assembly of a kind of high stability of the invention, between adjacent fuel pipe and fuel pipe and supporting plate it
Between be provided with spring, and spring be close to metal joint set towards the edge in fuel pipe direction, existing skill is solved with this
Fuel pipe in art causes also to produce with fuel oil pipe connector junction and shaken and deformation, finally because inside is twitched and produces vibrations
The problem of oil leak, extend the life-span of fuel pipe；
3rd, a kind of fuel oil tube assembly of high stability of the invention, damping device can effectively reduce fuel oil casing between vehicle body
Vibration transmission, vibration isolation rate TR can reach less than 0.1, further reduce vibrated rock of fuel oil casing and produce oil and shake noise
Problem.
