Embodiment 1

[0041] Embodiment 1: as figure 1 with 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 inner groove flow channel in the mandrel 2, and hollow out multiple spaces on the middle spacer 3. After vulcanization, use The rubber 4 and the multiple spaces form a plurality of liquid cavities 5 that are independent of each other, and liquid (not shown in the figure) is arranged in the multiple liquid cavities 5, and the inner groove flow path is passed between the multiple liquid cavities 5 connected. The liquid rubber composite joint formed by the above method can provide smaller radial stiffness and greater axial stiffness, and achieve a larger d...

Embodiment 2

[0059] Embodiment 2: This embodiment mainly describes another end structure of the runner groove, such as Figure 12 As shown, compared with Embodiment 1, the difference lies in that the runner groove 6 of this embodiment adopts oblique end portions. The dynamic stiffness provided by the node with oblique end runner grooves is less than that provided by the node with right angle end runner grooves, and the inflection point of frequency increase is generally in the range of 2-4Hz.

Embodiment 3

[0060] Embodiment 3: This embodiment mainly describes another end structure of the runner groove, such as Figure 13 As shown, compared with Embodiment 1, the difference is that the runner groove of this embodiment adopts a closed end. One end of this type of runner groove includes a closing runner groove 1 613 , a closing runner groove 2 614 and a closing runner groove 3 615 connected in sequence, and the closing runner groove 1 613 is connected with a mandrel through hole 213 Pass, the third runner groove 615 of the closed mouth is connected with the middle runner groove of the spiral runner groove 6. The other end portion of this type of runner groove also includes a closed runner groove 1 613 , a closed runner groove 2 614 and a closed runner groove 3 615 connected in sequence, which will not be repeated here.

[0061] The groove width K3 of the closed runner groove 1 613 is greater than the groove width K4 of the closed runner groove 2 614, and the groove width K5 of the...

Abstract

The invention discloses a method for forming a liquid rubber composite node with an inner groove flow channel and the node, wherein the forming method is to add an intermediate spacer between the outer casing and the mandrel, and bond the middle spacer and the mandrel through rubber vulcanization Together, the integrated intermediate spacer and mandrel are assembled into the outer casing; the inner groove flow channel is set in the mandrel, and multiple spaces are hollowed out on the middle spacer. After vulcanization, the rubber and the A plurality of spaces form a plurality of liquid cavities independent of each other, liquid is arranged in the plurality of liquid cavities, and the plurality of liquid cavities are connected through inner groove flow channels. The invention 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 an inner groove 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...
