A guide assembly for a twin tube shock absorber and a twin tube shock absorber

Abstract

The utility model relates to a kind of for the guide of double cylinder shock absorber and the shock absorber, the guide component includes guide unit and oil scraper ring, guide unit includes first annular step portion, second annular step portion and third annular step portion sequentially along first axial end to second axial end arrangement, three gradually reduce and transition are connected with inside diameter;Guide unit further includes axial through-hole, it is set in the side of third annular step portion towards second axial end, oil scraper ring is set in axial through-hole, and adjacent third annular step portion towards second axial end side, in the surface of third annular step portion and oil scraper ring opposite, in the surface of third annular step portion towards oil scraper ring, and / or in the surface of oil scraper ring towards third annular step portion is set with micro groove to guide fluid flow. By the above structural design, the guide component provided by the utility model can discharge gas in inner chamber, so as to avoid the influence of oil gas mixture on the damping characteristic of shock absorber.
