Abstract
The utility model relates to a damper piston valve adopting a jaw leaf-spring. The utility model is characterized in that the leaf-spring (3) of the intake valve is of stellar jaw leaf-spring, comprising a leaf-spring body (31) and a jaw end (32) of the leaf-spring; the leaf-spring body (31) and the jaw end (32) of the leaf-spring are connected into one body. The utility model can well locate the intake valve plates and ensure stable flow of fluid.
Description
Technical field
The utility model relates to the vibration damper field, is a kind of shock absorber piston valve of using pawl formula spring sheet specifically.
Background technique
At present, traditional circulation valve block that is used for the shock absorber piston valve is opened the valve pretightening force and is generally used the spring pretension, exist following deficiency with the spring pretension: at first, locate bad, when spring when axis is subjected to uneven load, the spring radial deformation is unequal, add spring and radially have only end spring holder location, thus in this case spring shaft to will with the axis runout of connecting rod, cause the location bad, influence the keying of circulation valve block, influence the performance of product; Moreover it is a step process that the circulation valve block is opened the valve process, and it is stable to be unfavorable for that fluid flows.
As mentioned above, there is following deficiency in prior art: bad to circulation valve block location, influence the keying of circulation valve block, and influence the performance of product; Opening the valve process is a step process, causes the fluid flowing instability.
Summary of the invention
The utility model has solved the bad to circulation valve block location of prior art existence, influences the keying of circulation valve block, influences the performance of product; Open the valve process and be a step process, cause the problem of fluid flowing instability, provide a kind of and had good positioning, open the valve process and be progressive formation application the shock absorber piston valve of pawl formula spring sheet.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of shock absorber piston valve of using pawl formula spring sheet, comprise piston, the flowing valve spring sheet that described piston upper-end surface is provided with, recovery throttle valve plate, recovery valve block, the centering spring seat that described piston lower surface inboard sets gradually, it is characterized in that described flowing valve spring sheet is astral pawl formula spring sheet, it comprises spring sheet body and spring sheet pawl end, and described spring sheet body and spring sheet pawl end are connected as a single entity.The design of pawl formula spring sheet makes elastic characteristic become nonlinear characteristics by the linear performance of original spring, makes original step opening feature become gradual change and opens, and has improved the characteristic of circulation valve block.
As preferably, the described spring sheet pawl end spring sheet body of postponing is inclined upwardly slightly, and described spring sheet pawl end each point is in same plane.Strengthened the intensity of spring lamellar body, made the circulation valve block has been taked multipoint positioning, improved and located bad shortcoming.
As preferably, described flowing valve spring sheet is provided with 3～9 pawls.Selecting the number of pawl according to actual needs, is good with 6.
As preferably, described some pawls are evenly distributed on the spring sheet body.Stressed evenly in order to make to the support of circulation valve block, be difficult for producing deviation.
The utility model is skillfully constructed, and the beneficial effect of generation is as follows:
1, pawl formula spring sheet overcomes radial deflection radially adopting certain cooperation to cooperate with connecting rod, and it is bigger to add pawl formula spring sheet integral rigidity, has reduced departing from of its axis and connecting rod axis.
2, the location with the circulation valve block changes point location into by original face location, has improved locating features.
3, the elastic characteristic of spring changes the nonlinear characteristics of pawl formula spring into by original linear performance, makes original step opening feature become gradual change and opens, and has improved the characteristic of circulation valve block.
