Problems solved by technology

[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 Guarantee over-curve performance and reduce wear; it is difficult for ordinary joints to achieve the above characteristics, especially for old lines, where the wear of wheels, rails and lines is high, 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

Embodiment 1

[0040] Embodiment 1: as figure 1 with figure 2 As shown, the liquid rubber composite node involved in the present invention includes an outer jacket 1, a mandrel 2 and an integral integral middle spacer 3 added between the outer jacket 1 and the mandrel 2, and the integral integral middle spacer 3 and The mandrel 2 is vulcanized and bonded together by rubber 4, and then the integrated integral middle spacer and the mandrel are assembled into the jacket 1; a flow channel is set in the jacket 1, and the integral integral middle spacer 3 is dug A plurality of spaces are formed in the void, and after vulcanization, a plurality of liquid cavities 5 independent of each other are formed with the rubber 4 and the plurality of spaces, and liquid (not shown in the figure) is arranged in the plurality of liquid cavities 5 and a plurality of The liquid cavities 5 are connected through flow channels.

Embodiment 2

[0054] Embodiment 2: as Figure 7 to Figure 9 As shown, compared with Embodiment 1, the difference lies in that the design structure of the flow channel is different. In this embodiment, the flow channel is formed as follows: the mandrel 2 is divided into inner and outer parts, the inner part is the mandrel body 212, and the outer part is the mandrel jacket 213, and the mandrel body 212 is interference fitted to the mandrel jacket 213 in. Runner grooves 6 are arranged on the outer peripheral surface of the mandrel body 212, and the runner grooves 6 are spirally distributed on the outer peripheral surface of the mandrel body 212. Here, the runner grooves 6 may not be spirally surrounded, Instead it is set in other shape. When the mandrel body 212 is interference-fitted into the mandrel outer cover 213, the inner peripheral surface of the mandrel outer cover 213 is used to block and seal the notch of the runner groove 6 to form an inner groove flow channel, so that the liquid ...

Embodiment 3

[0057] Embodiment 3: as Figure 10 As shown, compared with Embodiment 1, the difference lies in that the design structure of the flow channel is different. In this embodiment, the flow channel is formed as follows: In this embodiment, a through damping through hole 16 is provided on the mandrel 2 along the radial direction of the mandrel 2, and the upper liquid cavity and the lower liquid cavity are connected through the damping through hole 6. The liquid cavities are connected.

Abstract

The invention discloses a method for forming a liquid cavity through additionally arranging an integral type middle spacer sleeve. The method comprises the steps of firstly additionally arranging theintegral type middle spacer sleeve between a spindle and an outer sleeve, then caverning out the integral type middle spacer sleeve so as to form multiple spaces, adhering the integral type middle spacer sleeve and the spindle through rubber vulcanization, and utilizing rubber and the integral type middle spacer sleeve to form multiple liquid cavities independent mutually. According to the methodfor forming the liquid cavity through additionally arranging the integral type middle spacer sleeve provided by the invention, smaller radial rigidity and larger axial rigidity can be provided, and meanwhile, larger dynamic-static ratio is realized, so that the product performance of a liquid rubber compound node is optimized.

Description

technical field [0001] The invention relates to a method for forming a liquid cavity by adding an integral middle spacer, in particular to a method for forming a liquid cavity by adding an integral middle spacer. 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 principle of the liquid...
