Embodiment Construction

[0034] The basic idea of ​​the present invention is to add wear plates on the slave plate body, thereby reducing wear on the coupler frame.

[0035] In the present invention, the secondary plate body bears impact force during use. To ensure strength, the secondary plate body is made of Q275 material; in order to reduce wear on the coupler frame, a non-metallic wear plate is added at the contact position between the secondary plate body and the coupler frame. Among them, the wear plate is made of non-metallic material, which should have a suitable coefficient of friction:

[0036] In view of the characteristics of low friction coefficient, high and low temperature performance and high impact resistance of oily nylon, combined with the experience of using large quantities of oily nylon center disk wear discs and side bearing wear plates on railway wagons, the wear plate is made of oily nylon or other materials with the same characteristics. Manufactured from non-metallic materia...

Abstract

The invention discloses a slave plate structure for a railway good train coupler buffering device, which comprises a slave plate body and an abrasion plate, wherein the slave plate body is arranged in a coupler tail frame of the coupler buffering device; and the abrasion plate is arranged on one side of the slave plate body, and a main abrasion surface of the abrasion plate is contacted with the coupler tail frame. Because the abrasion coefficient of the abrasion plate is lower, abrasion is only generated on the abrasion plate, and the coupler tail frame has no abrasion basically. Therefore, the condition that the coupler tail frame needs to be welded due to transfinite abrasion cannot occur, and the problem of cracks due to improper welding of the couple tail frame is solved. When the abrasion of the abrasion plate exceeds the limit, only the abrasion plate needs to be replaced, and both the slave plate body and the coupler tail frame can be continuously used so as to save overhaul cost.

Description

technical field [0001] The invention relates to a railway freight car coupler, in particular to a slave plate structure used for a railway freight car coupler. Background technique [0002] The coupler buffer device is an important part of a railway vehicle, mainly composed of a coupler, a coupler frame, a coupler pin, a slave plate and a buffer. During the operation of the vehicle, the traction force between the vehicles is transmitted from the coupler, the coupler pin, the coupler frame, the buffer, and from the plate to the car body in turn. Among them, the coupler frame is a frame-type part that installs the slave plate and the buffer and bears the traction and impact of the vehicle. Its working condition is directly related to the safety of railway transportation. [0003] However, at present, the 13 (13A, 13B) coupler frames used in my country's trucks are equipped with secondary plates that are manufactured by forging, and there is a problem of large wear between the...
