Problems solved by technology

[0004] The purpose of the present invention is to provide a method for manufacturing and assembling a new elastic joint-like rubber elastic element and its products in view of the fact that the diameter-to-axis ratio of the existing elastic joint is still too large to meet the requirements of the existing vehicle.

Embodiment 1

[0025] by attaching Figure 1-2 It can be seen that the present invention is an elastic joint-like rubber elastic element, which includes a mandrel 1, a metal jacket 3 and elastic rubber 2, and is characterized in that: the metal jacket 3 has a two-half arc-shaped structure in the radial cutting direction, and the metal The axial cross-section of the jacket 3 is a convex truncated cone; the axial cross-section of the metal mandrel 3 is a concave truncated cone. After vulcanization, the metal jacket 1 and the elastic rubber body 2 are separated into rubber metal vulcanized bodies with gaps in the radial direction compared with the original diameter. The elastic rubber 3 and the metal jacket 3 are both discontinuous two-half structures. A tapered annular gap 4 is left between them. The metal jacket 3 cooperates with the metal mandrel 3 to form a concave space, and at the same time, there is a certain amount of eccentricity between the metal jacket 3 and the metal mandrel 3 in a...

Embodiment 2

[0030] Embodiment two is similar to embodiment one, and the difference is that the shape of the elastic rubber body 5 is a ring structure, and the rubbers of the two parts are connected together. ) is added with a rubber material, the added rubber material has the same shape as the rubber material in the main direction and is integrated with the rubber material in the main direction, which can effectively provide a smaller diameter-to-axis stiffness ratio.

[0031] The manufacturing method of embodiment two is the same as embodiment one.

Embodiment 3

[0033] Embodiment 3 is similar to Embodiment 1, the difference is that the shape of the elastic rubber body 6 is to partially increase the rubber material in the secondary direction space (that is, the gap between the two halves of the structure), and the added rubber material is an independent rubber block; the secondary direction rubber follows the main direction Rubber free has obvious air isolation section, which is independent from the rubber in the main direction, which can effectively adjust the performance of the product in the secondary direction.

[0034] The manufacturing method of the third embodiment is the same as that of the first embodiment.

Abstract

The invention relates to a method for manufacturing and assembling an elastic joint rubber elastic element and a product thereof. A metal sleeve, a metal mandrel and elastic rubber are bonded into rubber metal sulfide after being vulcanized at high temperature and pressure. The elastic element comprises the metal sleeve, the metal mandrel and the elastic rubber, wherein the metal mandrel is in aninner concave conical platform shape on the axial section; the elastic rubber is integrally vulcanized on the surface of the conical platform-shaped part of the mandrel; the inner surface and the outer surface of the elastic rubber are in an inner convex conical platform shape on the axial section, and the outer surface is vulcanized and bonded with the metal sleeve; the radial section direction of the metal sleeve is in a cambered two-piece structure; the metal sleeve is matched with the outer surface of the elastic rubber in shape, and the axial section is in an inner convex conical platform shape; the metal sleeve is embedded, meshed and vulcanized with the elastic rubber; and after being vulcanized with the elastic rubber, the two metal sleeves are separated to form rubber metal sulfide with a larger angular clearance along the radial direction compared with the original diameter.

Description

technical field [0001] The invention belongs to a damping component and its assembly method, in particular to a rubber joint elastic element product and its manufacturing method, which is mainly used in the rubber elastic elements used in the bogies of various locomotives and vehicles, and can also be applied to engineering Machinery and other parts of any vibration-damping elastic connection. Background technique [0002] Joint type rubber elastic element is a commonly used rubber-metal composite damping element, which can be widely used in various vibration damping places, especially in the bogie of rolling stock. The most common application is divided into two types: , one is a non-jacket structure, the product is composed of two parts connecting the mandrel and the outer rubber, and the other is a three-piece structure, the product is composed of the outer sleeve, the mandrel and the middle rubber. The common features of these two structures The characteristic is that t...
