Problems solved by technology

In order to form the stopper 31 made of block rubber, a method of sandwiching a mold filled with unvulcanized rubber between the upper and lower hot plates and heat forming is used, but as the thickness of the stopper 31 increases, There will be a difference in heat conduction between the surface and the interior of the limiting block, so that for the formed limiting block 31, there will be physical deviations in different parts

Embodiment Construction

[0049] Hereinafter, embodiments of the present invention will be described based on the drawings. figure 1 It is a vertical cross-sectional view showing a stopper for a railway vehicle according to the present invention, figure 2 It is an exploded cross-sectional view showing the stopper for a railway vehicle according to the present invention.

[0050] Such as figure 1As shown, the stopper 1 of the present invention has a shape in which a rubber elastic body is formed into a thick bowl shape or a barrel shape and turned upside down. A recess 2 with an open bottom is formed on the limiting block 1 . A disc-shaped upper plate 3 is fixed on the top of the limit block 1 , and a ring-shaped lower plate 4 is fixed on the bottom of the limit block. The bottom surface of the stopper 1 is formed in a ring shape, the inner side of the ring shape in the radial direction is made of rubber elastic body, and the outer side of the ring shape in the radial direction is made of the lowe...

Abstract

A stopper (1) is provided for a railway vehicle, the stopper being interposed between an air spring (21) and a truck, and the stopper (1) includes an outer body (5) made of a rubber elastic body and an inner body (6) made of a rubber elastic body disposed in the outer body (5) so as to be in contact with the outer body (5). In a method of manufacturing the stopper (1), the inner body (6) and the outer body (5) are separately vulcanized and molded before the inner body (6) is assembled into the outer body (5).

Description

technical field [0001] The present invention relates to a block-shaped stopper made of rubber elastic system, in particular to a stopper which can be easily molded when the stopper is a large stopper for railway vehicles, and its Manufacturing method. Background technique [0002] Conventionally, as shown in Patent Document 1, a stopper made of vulcanized rubber is known as a stopper for railway vehicles. Such as Figure 6 As shown, the stop block 31 of this structure is made of a block of vulcanized rubber, and is mostly adopted in European railways, and is expected to be used in large quantities in the future. In order to form the stopper 31 made of block rubber, a method of sandwiching a mold filled with unvulcanized rubber between the upper and lower hot plates and heat forming is used, but as the thickness of the stopper 31 increases, There will be a difference in heat conduction between the surface and the inside of the limiting block, so that for the formed limiting...
