Device for connecting splayed surface of steering frame swing bolster of lorry and vibration reducing abrasion plate

Abstract

The invention discloses a device for connecting a splayed surface of a steering frame swing bolster of a lorry and a vibration reducing abrasion plate, and mainly solves the problem of heat damage of the swing bolster due to thermal cutting and welding when the prior abrasion plate is repaired and replaced and the problem of abrasion of the swing bolster caused by other moving components of a steering frame. The device comprises the swing bolster and vibration reducing abrasion plates which are arranged on splayed surfaces at two ends of the swing bolster, the vibration reducing abrasion plate consists of a central inclined plane plate and two-wing vertical face plates both of which have a U-shaped symmetrical distribution structure, the outer surface of the central inclined plane plate and the splayed surface of the swing bolster form a joint assembly relation, and the outer surfaces of the two-wing vertical face plates and two lateral vertical faces of the splayed surface of the swing bolster form a joint assembly relation. The device is simple in structure and convenient for assembly, not only can ensure zero abrasion of the splayed surface of the swing bolster, but also can ensure that the two lateral vertical faces of the splayed surface of the swing bolster are not damaged, meet the replacement repair requirement of welding-free cutting of the vibration reducing abrasion plate, improve the working life, repair work quality and work efficiency of the swing bolster components.

Description

technical field [0001] The invention relates to a railway freight car bogie, in particular to a connection device between a bolster of a railway freight car bogie and a vibration-damping wear plate. Background technique [0002] Most railway freight car bogie vibration damping systems use friction damping technology. The main and auxiliary components are formed by the oblique wedge installed between the side frame and the bolster, the column surface of the central frame of the side frame and the slopes on the left and right sides of the bolster. rubbing surface. The slopes on the left and right sides of the two ends of the bolster are commonly referred to as bolster splayed surfaces by those skilled in the art because they are in the shape of a splayed figure. When the bogie is running, the vibration energy is consumed due to the friction generated by the relative motion between the wedge, the side frame and the bolster. In order to avoid or reduce the wear of the bolster ...

Problems solved by technology

This kind of parts replacement process is not only complicated to operate and inefficient, but also easily causes thermal damage to the bolster due to cutting and welding, which in turn affects the service life of the bolster

At the same time, since the two side facades of the bolster are exposed, other moving parts of the bogie damping system are also likely to rub against it when the vehicle is running, causing surface wear

[0004] A large number of railway freight car bogie repair operations have shown that: bolster damage caused by improper operation of the wear plate replacement on the bogie bolster, or damage caused by friction between other moving parts of the bogie vibration damping system, And the hidden dangers of vehicle operation safety caused by this have become a long-term problem that has plagued scientific researchers in the operation of railway wagons. Researchers have been working hard to explore an effective way to replace traditional welding mode wear plates, but so far the progress has been slow
