However, when the central shaft guide rod slides in the perforation of the sliding bushing, it often rubs against the inner wall surface of the sliding bushing at the same time, and the sliding bushing and the central shaft guiding rod are generally made of metal. Material, so the sliding bushing or the central shaft guide will gradually wear out during use, and finally lose its accuracy, resulting in unstable operation such as shaking and vibration. M345764 [New content] The purpose of this creation is to provide a slip group of a front fork steering tube shock absorber, which can be installed in the front fork steering tube to effectively reduce the friction and avoid it or The central shaft guide rod is gradually lost during use to ensure long-term use. For the above purposes, the slip sleeve assembly of the present invention comprises a set of seats and a bushing, wherein: the sleeve can be fixed to the bottom of a steering tube by a screwing method, etc., which can be made of metal Manufactured, and a central cavity is formed through a cavity; the δ海 bushing is made of a plastic material, which is fixed in the cavity of the sleeve by means of stamping, injection molding or post-closing; wherein the bushing A perforation corresponding to a central axis guide rod sliding portion is formed at a central portion, and the inner wall surface of the perforation is formed with a plurality of radial oil grooves, and the spacer wall of the perforated peripheral hole wall is formed with a plurality of through grooves concavely inwardly, and The top of the bushing extends a guide wall around the periphery of the perforation. Since the bushing is a malleable plastic material, when the center shaft guide rod slides into the perforation of the slip bushing, the center shaft guide bar will not be worn by the inner wall surface of the bushing perforation, and the The bushing can be used for a long time due to its wear resistance. In addition, by designing the oil groove and the groove on the inner wall surface of the bushing, the center shaft guide rod and the inner wall surface of the bushing perforation can provide a lubricating effect and reduce the contact area, thereby further reducing wear.
