Abstract
The present invention relates to a kind of buffer, and it has the shell of tubular and relative to the inside of above-mentioned shell piston rod with easy access, and the buffer main body produces the damping force relatively moved in the axial direction relative to above-mentioned shell for suppressing above-mentioned piston rod；It is characterized in that：Piston is provided with the piston rod；Liquid room is formed between the piston rod and cylindrical case；Some seal grooves are formed between the piston and cylindrical case；The liquid room in seal groove with being provided with sponge；By using between the shell of piston rod and piston and tubular, sponge is set, utilize the characteristic of sponge imbibition and discharge opeing, liquid reaches buffering effect by the buffer solution being squeezed in sponge, and due to buffer solution needs, this reduces the flow velocity of the liquid in buffering course for extrusion from sponge；In addition, sponge serves as absorber when buffer backhaul again, buffer solution is absorbed, accelerates the backflow of buffer solution, improves backhaul efficiency.
Description
Technical field
The present invention relates to a kind of buffer.
Background technology
Buffer is included shell and the piston rod of enclosure is inserted into a manner of with easy access.Buffer is in piston rod
Played when being moved axially relatively relative to shell for suppressing damping force of the piston rod relative to the relative movement of shell.Buffering
Device is installed between the vehicle body and axletree in such as vehicle, between car room and vehicle body, and can by play above-mentioned damping force and
Suppress the vibration of the vibration damping objects such as vehicle body, car room.
The mobile completion of piston rod is realized by the flowing of the fluid apertures progress liquid on piston in the liquid room of in general buffer
The buffering of energy and release；But the release of the too fast rate travel that result in piston rod of the flow velocity of in general fluid apertures and energy and
Buffering effect is undesirable；Therefore the buffering effect of buffer is improved to reduce flow rate of liquid needs a kind of new buffer to solve
Certainly this problem.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of buffer, can solve the problem that flow rate of liquid in general buffer
Very fast piston rod movement is fast, the problem of causing the buffering effect of buffer undesirable.
In order to solve the above technical problems, the technical scheme is that：A kind of buffer, it has the shell and phase of tubular
For the piston rod that the inside of above-mentioned shell is with easy access, the buffer is produced for suppressing above-mentioned piston rod relative to above-mentioned outer
The damping force that shell relatively moves in the axial direction；Its innovative point is：
Piston is provided with the piston rod；Liquid room is formed between the piston rod and cylindrical case；Outside the piston and tubular
Some seal grooves are formed between shell；The liquid room in seal groove with being provided with sponge；
Internal piston is provided with some vertical fluid apertures between the upper surface and lower surface of the piston；The lower end of the piston
Face bottom is disposed with an annular slab and a baffle plate along axis direction；The annular slab and piston lower surface and baffle plate it
Between formed accommodate liquid accommodating chamber；Side fluid apertures is provided with the annular slab；The external diameter of the annular slab is less than the outer of piston
Footpath.
Further, the flow velocity of liquid is more than the flow velocity of liquid in the fluid apertures of side in the flow velocity of the vertical fluid apertures.
Further, the bottom of the baffle plate and spring is additionally provided with the shell.
Further, it is connected with piston rod guide sleeve below the baffle plate.
Further, it is additionally provided with sealing ring on the seal groove.
The advantage of the invention is that：
1）Sponge is set by using between the shell of piston rod and piston and tubular in the present invention, using sponge imbibition and
The characteristic of discharge opeing, buffer are waited at work, and liquid reaches buffering effect by the buffer solution being squeezed in sponge, due to slow
This reduces the flow velocity of the liquid in buffering course for extrusion from sponge for fliud flushing needs；In addition, when buffer backhaul
Wait sponge and serve as absorber again, absorb buffer solution, accelerate the backflow of buffer solution, improve backhaul efficiency；Also by perpendicular in the present invention
The aperture of straight fluid apertures and side fluid apertures reaches the control purpose of flow velocity.
