Description
Technical Field
The utility model relates to a bumper shock absorber technical field, concretely relates to working cylinder indent bumper shock absorber.
Background
The common shock absorber adopts a finish rolling pipe with a smooth inner wall and roughness not greater than Ra0.8 as a working cylinder, and is largely used for shock absorber products due to the advantages of simple structure, short production period and the like, but the manufactured working cylinder cannot adapt to the use of various road conditions due to single damping value, and is particularly suitable for road sections with complex roads and more jolts and poor in filtering performance, so that the manufacture of the shock absorber adapting to various road conditions is important.
SUMMERY OF THE UTILITY MODEL
In order to overcome the technical problem, the utility model provides a working cylinder indent bumper shock absorber for it is single to solve current bumper shock absorber damping value, can not adapt to the technical problem of multiple road conditions.
The utility model provides a technical scheme that its technical problem adopted is: working cylinder indent bumper shock absorber, including the bumper shock absorber body, the bumper shock absorber body includes oil storage cylinder and working sleeve, and the working cylinder cover is established in the oil storage cylinder, and the oil storage cylinder intussuseption is filled with hydraulic oil, and piston rod coaxial cover are established in the working cylinder, and the oil storage cylinder tip seals, and the piston rod stretches out the department of sealing, the oil storage cylinder bottom of the cylinder is provided with the crotch, still is provided with spring tray on the oil storage cylinder body, be provided with the piston valve on the piston rod bottom of the piston rod piston valve, set up blotter and spacing ring between piston rod and the piston valve, the working cylinder is connected with oil storage cylinder bottom of the cylinder, and oil storage cylinder tip and working cylinder tip set up the director, be provided with the indent on the working cylinder body, indent and working cylinder body both ends junction rounding off.
Preferably, the working cylinder body is provided with at least one stamping groove, and the stamping groove is arranged along the axial direction of the working cylinder.
Preferably, the stamping groove is arranged on the working cylinder close to one end of the guide.
Preferably, the end seal of the oil storage cylinder is a spinning seal, and an oil seal is arranged between the guider and the seal.
Preferably, a bushing is arranged between the guide and the piston rod.
The utility model has the advantages that: the utility model discloses working cylinder indent bumper shock absorber adopts the inner wall smooth, and the roughness is not more than Ra0.8's finish rolling pipe, goes out the outside bellied groove of fixed shape at its inner wall punching press to this regard as its working cylinder. Through the design of this structure, the bumper shock absorber during operation produces two kinds of operating modes: firstly, when the piston valve moves in the working cylinder groove, unloading is generated, the damping force value is reduced, and the damping force value is more suitable for flat road conditions. And secondly, when the piston valve moves outside the working cylinder groove, the damping force value is relatively large, and the damping valve is more suitable for bumpy road conditions. Through the design of the structure, higher cost performance is obtained at lower cost.
