Abstract
The utility model relates to a shock absorber with a centring piece, which comprises a working cylinder, a bottom valve, an oil storing cylinder and an oil storing cylinder base, wherein the centring piece is arranged between the oil storing cylinder base and the bottom valve, an excircle of the centring piece is provided with a toothspace oil passing groove, and the fitting surface of the oil storing cylinder base as well as the bottom valve and the centring piece is a plane. Due to the central positioning and circumferential positioning by the centring piece, the assembling and centring effects are good, and the processing and assembling technology can be simplified, therefore, the assembling of the shock absorber is simper and more convenient as well as more reliable, and conditions of eccentric wear and abnormal sound and the like of a piston rod are effectively avoided after the shock absorber is assembled.
Description
Technical field
The utility model belongs to the damper components technical field, is that a kind of rail vehicles that is applicable to has the vibration damper of centering piece.
Background technique
In technique known, the rolling stock vibration damper is provided with parts such as clutch release slave cylinder, bottom valve, oil storage cylinder, oil storage cylinder base usually.When the assembling vibration damper, earlier bottom valve is pressed into clutch release slave cylinder one end, put into the oil storage cylinder assembly then, common consideration bottom valve and oil storage cylinder base are felt relieved with the conical surface in the design, in order to exceed the axial occupation space position, cone angle can not be provided with too smallly, so Location accuracy is just made a discount, in addition in the production process of reality, because the machining deviation of part, the inclined-plane of bottom valve and oil storage cylinder base is difficult to realize that angle is in full accord, and in assembly process, operator can't judge accurately whether the bottom valve center overlaps with the oil storage cylinder center.The situation that will occur the misalignment oil storage cylinder center of bottom valve like this causes bad phenomenon such as vibration damper assembling back piston bar eccentric wear, vibration damper abnormal sound, will directly cause the vibration damper lost of life, inefficacy etc.
In lateral damper and the anti-vibration damper that crawls, because its axis is horizontal positioned in use, bottom valve is easy to generate displacement, influences effectiveness in vibration suppression.
Summary of the invention
The purpose of this utility model provides a kind of clutch release slave cylinder and bottom valve can accurately realized and locatees, the reliable coaxality that guarantees clutch release slave cylinder and oil storage cylinder, avoid situations such as vibration damper assembling back piston bar eccentric wear, abnormal sound, guarantee quality of product, and the energy simplified processing process, the vibration damper that has centering piece easy to assembly.
The realization technical solution adopted in the utility model is: this vibration damper comprises clutch release slave cylinder, bottom valve, oil storage cylinder and oil storage cylinder base, wherein, between oil storage cylinder base and bottom valve, be provided with centering piece, the cylindrical of this centering piece has the logical oil groove of between cog, and the fitting surface of oil storage cylinder base and bottom valve and centering piece is the plane.
Described centering piece is provided with positioning pawl, and the positioning hole that is provided with on this positioning pawl and the oil storage cylinder base cooperates.
The vibration damper of making according to such scheme, by the center and the axially locating of centering piece, not only assembling centering is effective, and the conical surface of oil storage cylinder base and bottom valve can change the plane into, has simplified processing and assembly technology; Can effectively avoid simultaneously situations such as vibration damper assembling back piston bar eccentric wear, abnormal sound, quality of product is effectively guaranteed.This vibration damper is applicable to vertical damper, lateral damper and the anti-vibration damper that crawls.
Description of drawings
Fig. 1 is the part-structure schematic representation of the utility model vertical damper;
Fig. 2 is an employed vertical centering piece structural representation among Fig. 1;
Fig. 3 be the utility model laterally and the part-structure schematic representation of the anti-vibration damper that crawls;
Fig. 4 is employed horizontal, the anti-centering piece structural representation that crawls among Fig. 3.
Embodiment
Referring to Fig. 1, Fig. 2, be the vertical damper that the utility model has centering piece, each label is respectively among the figure: clutch release slave cylinder 1, bottom valve 2, oil storage cylinder 3, oil storage cylinder base 4, centering piece 5; Between cog leads to oil groove a, b, c.Wherein, centering piece 5 is arranged between oil storage cylinder base 4 and the bottom valve 2, and these centering piece 5 usefulness sheet metal punching out form, and its cylindrical has between cog logical oil groove a, b, c.The internal diameter of centering piece 5 cooperates with bottom valve 2 step place crest clearances, the tooth external diameter of centering piece 5 and oil storage cylinder 3 internal diameter Spielpassung.During assembling centering piece 5 is installed between clutch release slave cylinder 1 and the bottom valve 2, puts into oil storage cylinder 3 then, with the tooth cylindrical location of centering piece 5, to guarantee the coaxality of clutch release slave cylinder 1 and oil storage cylinder 2.The logical oil groove a of centering piece 5, b, c can be used as the fluid passage, to guarantee the vibration damper proper functioning.
Referring to Fig. 3, Fig. 4, be horizontal, the anti-vibration damper that crawls that the utility model has centering piece, each label is respectively among the figure: clutch release slave cylinder 1, bottom valve 2, oil storage cylinder 3, oil storage cylinder base 4, centering piece 5, the circumferential witness marker groove of oil storage cylinder B, positioning hole A and between cog lead to oil groove a, b, c.Because the horizontal or anti-vibration damper level on vehicle of crawling is installed, needing increases circumferential positioning device, thereby is provided with positioning pawl X on centering piece 5.On oil storage cylinder base 4, add and bore positioning hole A, suppress the circumferential witness marker groove B corresponding on the oil storage cylinder 3, to guarantee the relative position of oil storage cylinder 3 and oil storage cylinder base 4 circumferential witness marker groove B and positioning hole A when the welding with positioning hole A position.The internal diameter of centering piece 5 cooperates with bottom valve 2 step place crest clearances, the big external diameter of centering piece 5 and oil storage cylinder 3 internal diameter Spielpassung, and positioning pawl X matches with oil storage cylinder base positioning hole A.During assembling centering piece 5 is installed between clutch release slave cylinder 1 and the bottom valve 2, put into oil storage cylinder 3 then and guarantee that the positioning pawl X on the centering piece 5 falls into the positioning hole A of oil storage cylinder base 4, the cylindrical location of centering piece 5 guarantees the coaxality of clutch release slave cylinder 1 and oil storage cylinder 3, and positioning pawl X can make the circumferential positioning device of vibration damper.The between cog of centering piece 5 leads to oil groove a, b, c can be used as the fluid passage, to guarantee the vibration damper proper functioning.
Claims (2)
