Problems solved by technology

[0008] In addition, the thickness of the rubber layer of the existing axle box rubber pad is generally thin, the vertical disturbance of the rubber pad is low, and the low dynamic effect is average. However, simply increasing the thickness of the rubber layer will increase its lateral stiffness and weight, which is not conducive to steering. rack curve through performance

Embodiment Construction

[0031] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Please refer to figure 2 , figure 2 It is a schematic diagram of an integrated bearing saddle rubber pad in an embodiment of the present invention.

[0033] The integrated bearing saddle rubber pad provided by the present invention is arranged with an upper liner 10, a rubber layer 20, and a bearing saddle 30 from top to bottom, wherein the upper liner 10 and the rubber layer 20 form an integral structure through vulcanization, and the rubber The layer 20 is directly formed into an integrated structure with the bearing saddle 30 through a vulcanization process.

[0034] Compared with the rubber pad with the lower liner in the prior art, in the present invention, the rubber layer 20 and the bearing saddle 30 are...

Abstract

The invention discloses a railway vehicle bogie and an integrated adapter rubber blanket thereof. The integrated adapter rubber blanket comprises an upper liner plate and a rubber layer vulcanized on the lower surface of the upper liner plate and is characterized by comprising an adapter, the rubber layer is located between the upper liner plate and the adapter, and the adapter and the rubber layer are molded into an integrated structure through a vulcanization technology. Due to the fact that the rubber layer and the adapter are directly molded into the integrated structure through the vulcanization, connection between a lower liner plate and the adapter is not needed; due to the fact that the lower metallic liner plate is omitted, the transverse rigidity of the whole rubber blanket can be greatly lowered, the overall curve negotiating performance of the rubber blanket and the adapter is improved, and the friction problem between the lower liner plate and an adapter in the prior art is solved.

Description

technical field [0001] The invention relates to the field of railway freight car bogies, in particular to a railway vehicle bogie and an integrated bearing saddle rubber pad. Background technique [0002] In railway vehicles, the bogie is used to support the car body, guide the vehicle along the track, and bear various loads from the car body and the line. It is the main force-bearing part in the operation of the railway vehicle. Therefore, the performance of the bogie is good Damage directly affects the reliability and stability of vehicle operation. [0003] The most common type of railway freight car truck is the three-piece truck, which includes a bolster, two sideframes, and two wheelsets. Among them, the bolster is connected with the side frame to control the movement of the side frame; the side frame is connected with the wheel set, and the movement of the wheel set is controlled by the friction between the two; the two ends of the wheel shaft of the wheel set are pr...
