Abstract
The utility model relates to a guide seat for improving the sealing performance of an oil pressure vibration absorber for a rail transit vehicle, wherein a main body of the guide seat is provided with a through hole, and the inner wall of the through hole at the middle part is provided with a plurality of oil seal grooves for arranging oil seals to carry out multilayer sealing; the upper end and the lower end of the main body of the guide seat are respectively provided with a step, and the middle of the main body of the guide seat is provided with a sealing groove. The utility model discloses a carry out optimal design to the guide holder structure, all design the multilayer seal inside the guide holder main part and outside respectively, improved the leakproofness of guide holder, prevented effectively that the fluid of fluid shock absorber from leaking outward.
Description
Technical Field
The utility model belongs to the technical field of rail transit vehicle fluid shock absorber, concretely relates to improve guide holder of oil pressure shock absorber leakproofness for rail transit vehicle.
Background
Currently, oil pressure dampers are widely used in railway rolling stock. The oil pressure shock absorber moves back and forth by stretching and compressing the piston rod, and when oil flows in the oil cylinder, the oil passes through the damping valve to form damping force, so that the purpose of vibration reduction is achieved, and the oil pressure shock absorber is an important part for improving the smoothness, the safety and the comfort of high-speed running of locomotives and vehicles. Wherein, in use, the oil does not leak out, which is one of the basic requirements of the oil pressure vibration damper. In the operation of the shock absorber, the piston rod frequently moves back and forth, so how to ensure the sealing performance of the shock absorber in terms of measures for preventing oil leakage of the shock absorber, and preventing oil from leaking out becomes an important research subject for ensuring the service performance of the hydraulic shock absorber.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art not enough, provided an improve guide holder of oil pressure shock absorber leakproofness for rail transit vehicle, the utility model discloses a carry out the optimal design to the guide holder structure, all design the multilayer seal inside the guide holder main part and outside respectively, improved the leakproofness of guide holder, prevented effectively that the fluid of fluid shock absorber from leaking outward.
For solving one of above-mentioned technical problem at least, the utility model discloses the technical scheme who takes is:
a guide seat for improving the sealing performance of an oil pressure shock absorber for a rail transit vehicle is characterized in that a main body of the guide seat is provided with a through hole, the through hole is used for being sleeved on a piston rod of the oil pressure shock absorber to guide and limit the piston rod, and the inner wall of the through hole in the middle is provided with a plurality of oil seal grooves for arranging oil seals to perform multi-layer sealing; the upper end and the lower end of the main body of the guide seat are respectively provided with a step for placing a sealing element, and the middle part of the main body of the guide seat is provided with a sealing groove for placing the sealing element.
Furthermore, the main part of guide holder still inclines to be equipped with oil return passage, just oil return passage with the oil blanket groove is linked together, the oil return of being convenient for.
Further, the sealing element is an O-shaped ring.
The beneficial effects of the utility model include at least: the utility model discloses a carry out the optimal design to the guide holder structure, it is sealed all to design the multilayer in the guide holder main part inside and outside respectively, has improved the leakproofness of guide holder, can effectively avoid because reasons such as O type circle damage, ageing lead to sealed becoming invalid, lead to oil hydraulic shock absorber to take place the oil leak trouble.
Drawings
Fig. 1 is a schematic view of the structure of the guide seat of the present invention.
The oil seal structure comprises a main body 1, a through hole 2, an oil seal groove 3, a step 4, a seal groove 5 and an oil return channel 6.
Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the following specific embodiments. The following description of the embodiments is merely exemplary in nature and is in no way intended to limit the invention. The examples, where specific techniques or conditions are not indicated, are to be construed according to the techniques or conditions described in the literature in the art or according to the product specifications.
Example 1: fig. 1 is the utility model discloses guide holder structure schematic diagram, it is shown with reference to fig. 1 to improve guide holder of oil pressure shock absorber leakproofness for rail transit vehicle, its main part is equipped with well logical through-hole for the cover is located right on oil pressure shock absorber's the piston rod lead to the piston rod spacing be equipped with a plurality of oil seal grooves on the inner wall of middle part through-hole for it carries out the multilayer seal to set up the oil blanket, has improved the leakproofness between guide holder and the piston rod effectively. According to the utility model discloses an embodiment, the utility model discloses preferred is three oil blanket groove, certainly can also be for more quantity, specifically designs according to the actual demand.
The utility model discloses an in this embodiment, the main part upper end and the lower extreme of guide holder are equipped with the step respectively for place the sealing member, and the main part middle part of guide holder is equipped with sealed recess, is used for placing the sealing member, carries out the multilayer and seals, improves the leakproofness between direction lid and oil damper's the outer cylinder.
The utility model discloses an in this embodiment, the main part of guide holder still slopes to be equipped with oil return passage, just oil return passage's one end with the oil blanket groove is linked together, and the other end is linked together with the oil storage chamber that oil damper's outer jar and inner tube formed, and the oil return of being convenient for prevents that fluid from leaking outward.
In this embodiment of the present invention, the sealing member is an O-ring.
To sum up, the utility model discloses a carry out the optimal design to the guide holder structure, all design the multilayer seal inside the guide holder main part and outside respectively, improved the leakproofness of guide holder, can effectively avoid because O type circle damages, reasons such as ageing lead to sealed becoming invalid, lead to oil hydraulic shock absorber to take place the oil leak trouble.
Although embodiments of the present invention have been shown and described, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that various changes, modifications, substitutions and alterations can be made in the above embodiments by those skilled in the art without departing from the scope of the present invention, and that various changes in the detailed description and applications can be made by those skilled in the art without departing from the spirit of the present invention.
