Description

Technical Field

[0001] The utility model relates to the field of node maintenance, in particular to a lubricating device for a node of a suspension rod of a motor vehicle group. Background Art

[0002] EMU, also known as "EMU train", is a type of modern train. The suspension system of EMU is an important guarantee for the normal operation of rail transit vehicles. It improves the dynamic performance of vehicle operation, eliminates stability problems that occur during vehicle operation, and provides passengers with a safe, fast and comfortable riding experience. However, as the service life of the EMU increases, the suspension system will age and wear, which will cause stability, safety and stability problems during the operation of the EMU, which will have a certain impact on the travel safety and riding experience of passengers. Among them, the suspension rod node is one of the important components in the EMU suspension system, which mainly plays the role of connection and shock absorption. Therefore, after the EMU has been working for a period of time, the suspension rod node must be inspected and repaired to ensure the performance of the EMU during operation.
