Abstract

A lightweight low cost damping assembly having a piston rod on which a piston is formed such that fastener elements are not needed to secure the piston onto the piston rod. Preferably, the piston rod is formed by chrome plating the exterior of a tubular steel rod except at a piston attachment portion. The piston attachment portion is specially shaped such that the piston may be formed thereon and coupled thereto by the inter-engaging of the piston with the shape of the piston attachment portion. Most preferably, the piston attachment portion is in the form of shallow grooves, knurls or dimples in the exterior of the piston rod and the piston is injection molded thereon. The material of the piston molds itself into the shape of the piston attachment portion, thereby resulting in a secure coupling between the piston and the piston rod.

Reference to the Invention (&); Reference to the Orange Pass Application The present invention requests the earliest application of US patent application G G / 0 51, Π 3 fi, which was filed on July 3, 1997. BACKGROUND OF THE INVENTION The present invention relates to the design and construction of cold rods and piston assemblies. The invention particularly relates to a lightweight and low-cost damping assembly device and a manufacturing method thereof. The dummy device includes a piston rod, and a damping piston is directly injection-molded thereon, and is used in a damping system of a suspension system. Don't use it for high-performance bicycle suspension systems. Many systems use piston rods with pistons mounted on them. Piston rods and piston assemblies are typically used in hydraulic damping systems with a damping fluid box. The piston passes through the damping box, and the piston mounted on it slides through the fluid in the box to generate damping. Such hydraulic damping systems are known to be provided in suspension systems such as those used in the fields of motorcycles, automobiles, and bicycles. For example, U.S. Patent No. 5,45 β, 480 has disclosed a suspension system for a bicycle frame with a damping system, which was pseudo-issued to nererner et al. ("'480 patent" ) And the person authorized to the present invention, please provide its full picture, for your reference. The '48G patent bicycle rack has a replaceable cassette assembly. The box button includes a cylindrical box body filled with hydraulic oil. A piston with a piston assembly installed passes through the box 赗, and the 俾 piston assembly can slide inside the box. The cassette assembly further has an I® seal at both ends, sealing the point where the piston rod passes through the end of the cassette body. The piston rod extends through the box seal at the two ends of the box body, and the piston divides the box into two chambers, and engages the inside of the box to seal the first chamber, so that it is isolated from the second slaughter e hole penetrates the living wall and the living wall.

The solution is compared to the example of the face plug 1Π34, where the inner end of t is only 10, and the live end is t10. Painted in P live 34, the outer rod is 1S, and it is described as 28¾. Supposed, 10 pass through the Sénéveés] ¾ tube), Supposed that the deceased person accepts Sekidiko 8a, and defends the period The work needs to be performed on 30 of the 3031 outside the Ming dynasty. It is more difficult to use the colder than the 32,3, so the # is as high as the 1022 pieces, you need to draw a 30-shaped warp to make a steel frame.五 Ά J] Order (" Read the notes on the back before filling this page) 445228 Α7 Β7 V. Description of the invention u) The cold assembly 411 is installed on the piston rod 10 and the assembly and defense assembly is used in As shown in Article 1_3 and Article 2 2 above, the cold assembly 40 will block {read the precautions on the back before filling in this page} The box 3 4 is divided into two rooms. In order to allow the tritium fluid to flow from one chamber to the other for damping the system, at least one of the piston 10 and the piston assembly 40 are most preferred, and at least one channel is preferably provided in both. Holes to allow fluid flow through these chambers. When the through hole is provided in the piston rod 10, the piston rod 10 is generally hollow from the end portion 12 to the end portion 14. However, as described above, the wall portion of the piston rod 10 should be as thin as possible to reduce the weight of the system. However, the thin wall of the piston rod 10 must allow the piston assembly 4G to be mounted on it. In a preferred embodiment as shown in FIG. 2, at least the plastic piston 42 of the piston assembly 4G is directly injection-molded on the piston connecting portion 44 of the piston rod 10 as shown in FIGS. 3 and 4. Of course, it has been observed that nylon 6.6 is very effective in the injection molding of pistons, but any type of plastic or other formable materials can be used. As noted above, the piston rod 10 is preferably chrome-plated. However, in order to facilitate the connection of the piston 42 to the outside of the piston 10, it is preferable that the piston connection portion 4 is not chrome-plated. Β, such as a knurled surface, a row of pits or holes arranged in the piston rod 10, or the piston rod 10 may be used. Various fixing devices such as warping or cutting grooves or other grooves are used to determine the positioning and fixing of the piston 42 on the piston rod 10. However, the piston connecting portion 44 of the piston rod 10 should preferably include one or more shallow grooves, and preferably includes continuous, spiral shallow grooves as shown in Figs. These grooves provide sufficient surface area so that the plastic connection of the piston 42 itself can be fixed on the guard 10 to prevent the living wall 42 from swimming towards the first end 12 or the second end 14 of the living cold guard 1. In addition. The spiral shape of the groove prevents the cold 42 from rotating on the piston guard 10. The paper size of the piston is free from the Chinese national standard (CNS > A4 specification (210X297 mm))
