Abstract
A diameter-change cylinder liner hydraulic buffer is provided by the utility model, which belongs to the buffer field. The utility model comprises a cylinder liner, a piston in the cylinder liner and a buffer piston rod connected with the piston. The cylinder liner consists of at least a conical collapsible tube, an unloading straight tube, a conical amplifying tube and a uniform speed straight tube by connection. The utility model has the advantage of excellent cushioning effect.
Description
Technical field
The utility model relates to hydraulic bjuffer, refers in particular to that to be used for the spring be a kind of reducing cylinder sleeve hydraulic bjuffer of kinematic pair buffering of power.
Background technique
At present, buffer of a great variety, but the widest with the application of hydraulic bjuffer.Traditional hydraulic bjuffer cylinder sleeve is the cylindrical shell of diameter unanimity, and cushion effect is that earlier little back is big; And kinematic pair commonly used adopts spring to be used as power usually, and not only simply but also with low cost, and the active force of spring is first big after small, traditional hydraulic bjuffer is because of adopting the back off-load of slowing down earlier, and is when loads change, not in place in the time of will small load occurring, head-to-foot during big load, lose buffer function.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of reducing cylinder sleeve hydraulic bjuffer of, good buffer effect consistent with spring force is provided.
The purpose of this utility model is achieved in that a kind of reducing cylinder sleeve hydraulic bjuffer, comprise cylinder sleeve, be arranged on piston and the damper piston bar that is connected with piston in the cylinder sleeve, wherein: described cylinder sleeve be by at least one section conical converging section, one section off-load straight length, one section taper amplification pipeline section and one section at the uniform velocity straight length be formed by connecting.
Cylinder sleeve described in the above-mentioned reducing cylinder sleeve hydraulic bjuffer by conical converging section, off-load straight length, taper amplify pipeline section and at the uniform velocity straight length be connected in sequence, can form the cushion effect consistent with spring force.
Be provided with one-way valve in the piston described in the above-mentioned reducing cylinder sleeve hydraulic bjuffer, make things convenient for the piston returning quickly.
Be provided with return spring in the cylinder sleeve described in the above-mentioned reducing cylinder sleeve hydraulic bjuffer, so that the piston self-return.
After the utility model adopts said structure, utilize the gap between piston and the inboard wall of cylinder liner to change, realize buffer function, have the buffer function power consistent, the advantage of good buffer effect with spring force; And,, can design the buffer that satisfies different usage requirements by the various combination variation of Taper Pipe section and straight length for the design of hydraulic bjuffer provides a new thinking.

Embodiment
Consult shown in Figure 1, reducing cylinder sleeve hydraulic bjuffer of the present utility model, comprise cylinder sleeve 1, be arranged on piston 2 and the damper piston bar 3 that is connected with piston 2 in the cylinder sleeve 1, cylinder sleeve 1 by conical converging section 11, off-load straight length 12, taper amplification pipeline section 13 and at the uniform velocity straight length 14 slip and form in Lianping successively; In piston 2, be provided with ball type one-way valve 4.
The concrete working principle of the utility model is consulted Fig. 2 to shown in Figure 5:
In Fig. 2, piston 2 moves right, and enters in the conical converging section 11, and because of the caliber of this section diminishes gradually, the resistance that piston 2 moves increases gradually, can play decelerating effect.
In Fig. 3, piston 2 continues to move right, and enters off-load straight length 12, and because of the gap minimum between this section and the piston 2, fluid is subjected to pushing greatly flowing to left oil pocket with the high speed small flow, and kinetic energy is transformed into heat energy, by cylinder sleeve 1 heat radiation, produces the off-load effect.
In Fig. 4, piston 2 continues to move right, because in off-load straight length 12 off-load, speed is slowed down, piston 2 enters after taper amplifies pipeline section 13, and because of the caliber of this section increases to stablely gradually, the moving of piston 2 becomes gradually and at the uniform velocity enter at the uniform velocity straight length 14 and be parked in the fixed position.
In Fig. 5, show that piston 2 is moved to the left return under the effect of external force, at this moment, the one-way valve 4 in the piston 2 is opened, and the fluid of left oil pocket can be by in the right oil pocket of one-way valve 4 fast flow speed and directions.
Consult shown in Figure 6ly, reducing cylinder sleeve hydraulic bjuffer of the present utility model is on embodiment 1 basis, is provided with return spring 5 in cylinder sleeve 1, can make piston 2 self-return after buffering work easily.
