Embodiment 1

[0040] Embodiment 1: as figure 1 and figure 2 As shown, a method for forming a liquid rubber composite node with an inner groove flow path, which is to add an intermediate spacer 3 between the outer casing 1 and the mandrel 2, and bond the intermediate spacer 3 and the mandrel 2 through rubber 4 vulcanization. Connect together, and then assemble the integrated intermediate spacer and mandrel into the outer casing 1; set the pipe body flow channel in the mandrel 2, and hollow out multiple spaces on the middle spacer 3. After vulcanization, use The rubber 4 and the plurality of spaces form a plurality of liquid cavities 5 that are independent of each other. Liquids (not shown in the figure) are arranged in the plurality of liquid cavities 5, and the plurality of liquid cavities 5 pass through pipe flow channels. 6 phases are connected. The liquid rubber composite joint formed by the above method can provide smaller radial stiffness and greater axial stiffness, and achieve a l...

Embodiment 2

[0057] Embodiment 2: as Figure 11 As shown, compared with the embodiment 1, the difference of the present embodiment is that: the two ends of the coat 1 in the present embodiment adopt the cuff buckle design structure. One end of the intermediate spacer 3 is provided with a continuous step portion 14 and a step portion 2 15, the step portion 14 is located at the lower position (close to the mandrel), and the step portion 2 15 is located at the upper position (away from the mandrel) position), one end face of the jacket 1 is vertically flush with the lateral vertical surface of the step part 2 15, and an end sealing ring 16 is placed on the step part 2 15. When the flange is not crimped, the end sealing ring The height of 16 is higher than the height of step part 2 15, that is, the end sealing ring 16 is located between the step part 2 15 and the outer casing 1. A jacket flanging part 112 is extended on one end surface of the jacket 1. During the flanging operation, the end s...

Abstract

The invention discloses a method for forming a liquid rubber composite node with a pipe body flow passage and a node, wherein the forming method comprises the steps of additionally arranging a middlespacer sleeve between an outer sleeve and a core shaft, vulcanizing and bonding the middle spacer sleeve and the core shaft together through rubber, and assembling the middle spacer sleeve and the core shaft which are integrally formed into a whole into the outer sleeve; and arranging the pipe body flow passage in the core shaft, forming a plurality of spaces in the middle spacer sleeve by hollowing, after vulcanization, forming a plurality of liquid cavities independent of each other by the rubber and the plurality of spaces, arranging liquid in the plurality of liquid cavities, and the liquid cavities communicating with one another through the pipe body flow passage. The method for forming the liquid rubber composite node with the pipe body flow passage and the node can provide smaller radial rigidity and larger axial rigidity, and realize larger dynamic-static ratio, thereby optimizing the product performance of the liquid rubber composite node.

Description

technical field [0001] The invention relates to a method for forming a liquid rubber composite node and a node product, in particular to a method for forming a liquid rubber composite node with a pipe flow channel and the node. Background technique [0002] According to the dynamic requirements, when the pivoting arm node is running in a straight line at high speed (high frequency vibration), it provides a large radial stiffness to ensure the running stability and increase the critical speed; when it passes the curve (low frequency and large amplitude), it provides a small stiffness performance Guaranteed over-curve performance and reduced wear; it is difficult for ordinary joints to achieve the above characteristics, especially for old lines, where wheel rails and lines wear a lot, and the maintenance cost is high. Therefore, it is necessary to use a new product that has the above characteristics at the same time—liquid rubber composite joints. [0003] The working principl...
