Description

Technical Field

[0001] The utility model relates to the field of rail trains, in particular to a hanging arm used on rail trains. Background Art

[0002] Since rail trains run on dedicated lanes, they are not interfered with by other means of transportation, do not cause line congestion, and are not affected by the climate. They are all-weather means of transportation. The trains can run according to the timetable and have reliable punctuality. Compared with conventional public transportation, rail trains run on dedicated lanes and are not interfered with by other means of transportation. The vehicles have higher running speeds, higher starting and braking accelerations, most of them use high platforms, train stops are short, boarding and alighting are quick and convenient, and transfers are convenient, so passengers can reach their destinations faster and shorten travel time.

[0003] However, the suspension arm currently used on rail trains is an integral structure. After long-term use, the fixed structure is prone to breakage. When the direction is changed, it is more likely to be worn out due to the change in force direction, which poses a safety hazard and is extremely inconvenient to use.

[0004] In view of this, research and improvements are conducted on the existing problems, and a hanging arm for rail trains is provided, which has a reasonable structural design. When the direction is changed, the small slider on the inner surface of the slide rail can move horizontally to offset the safety hazards caused by uneven force as much as possible, and the threaded rotating rod can move vertically with the U-shaped fixing plate to reduce excessive force when driving at high speed. The purpose is to solve the problem and improve the practical value through this technology. Utility Model Content
