DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to wear liner components for bolster bowls of railcar bogies and lubrication thereof, and in particular, the present invention is used for such bogies of bogies. And a liner assembly for both wear and lubrication.

[0002]

BACKGROUND OF THE INVENTION During the operation of a train, a rotatable connection is required to pass through a curve (bent path) encountered by a bogie structure.
It is well recognized from both maintenance and design engineering in the railway industry that what must be done between the body part and the bogie part of the railway vehicle. This connection is typically made in a standard railway vehicle using an upper plate fixed to the bottom of the body along a longitudinal center axis.
And these bolster bowls are arranged on the upper part of the bogie of the railway vehicle. However, in this articulated coupling device which is used to connect adjacent ends of a pair of railcars together in a substantially semi-permanent manner, the rotatable connection is a female connection member and a bolster bowl. Is done between

In general, lubricating the rotatable connection is considerably more difficult. Moreover, keeping enough lubricant in place is even more difficult because the environment encountered is very poor. For example, during the operation of a train in a storm, moisture can quickly wash away the lubricant used from the bolster bowl. This lack of lubrication in critical areas can result in excessive friction wear on vehicle components, thereby increasing repair and maintenance costs. Furthermore, the lack of lubrication, which is very relevant for the railway industry, leads to derailment in the most severe cases. Obviously, this will result in damage or damage to the cargo carried by the railroad, and will significantly increase the cost of doing business.
