The embodiment also provides a rail vehicle, including the automobile body, set up the pantograph on the automobile body and be used for the lag subassembly including the tuber pipe 30 of pantograph, the lag subassembly is foretell lag subassembly.

In this embodiment, owing to set up the protective sheath subassembly to make protective sheath 10 can carry out effectual protection to tuber pipe 30, and ribbon 20 can make protective sheath 10 fasten in the periphery installation of tuber pipe 30, is difficult for droing, and then has improved pantograph tuber pipe 30's anti-hitting ability and life greatly.

Therefore, the rail vehicle with the protective sleeve assembly also has the advantages.

In this embodiment, the pantograph includes a sliding plate structure, and the air duct 30 is connected with the sliding plate structure, and the sliding plate structure has an air flue, and the air flue communicates with the air duct 30.

A plastic air pipe 30 with the outer diameter of 6mm and the wall thickness of 1mm is installed on a pantograph of a railway vehicle, the air pipe 30 is connected with a sliding plate structure of the pantograph, and an air passage is arranged inside the sliding plate structure. When the air duct 30 is filled with air, the air passage of the slide plate is also filled with compressed air. When the rail vehicle runs at high speed, the sliding plate structure is in sliding contact with the contact network wire. When the sliding plate structure is hit by foreign matters or reaches the friction limit of the sliding plate structure, air leaks from an air passage of the sliding plate structure, so that automatic bow lowering is caused, and the guiding safety of the railway vehicle is influenced.

When the rail vehicle runs at a high speed, the air pipe 30 of the pantograph is exposed and leaked in the environment, and the influence of foreign object striking and surrounding environment is avoided, so that the air pipe 30 is damaged and leaked, the pantograph of the rail vehicle is automatically lowered and increased, and the running order of the rail vehicle is influenced. According to the structural characteristics of the pantograph, the air pipe 30 at the movable joint part of the pantograph cannot be completely fixed, a section of suspension part needs to be reserved, and the air pipe 30 swings back and forth due to the fact that the air pipe 30 is disturbed by high-speed airflow during driving, so that stress concentration at the joint of the air pipe 30 is caused, and a weak point is formed. When the air duct 30 is hit by a foreign object, air leakage often occurs at a joint contact portion (weak point) with the air duct 30 due to a pulling force.

Therefore, in order to improve the anti-impact capability of the air duct 30 and reduce the influence of the external natural environment on the air duct 30, the present embodiment provides the above-mentioned protective sleeve assembly, which has a protective effect on both the joint section and the tail pipe section of the air duct 30 and reduces the swing frequency of the air duct 30 at the suspension part. The arrangement greatly improves the anti-impact capability and the service life of the pantograph air pipe 30.

From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects:

owing to set up the protective sheath subassembly to make protective sheath can carry out effectual protection to the tuber pipe, and the ribbon can make protective sheath install the fastening in the periphery of tuber pipe, is difficult for droing, and then has improved the anti ability of beating and the life of hitting of pantograph tuber pipe greatly. Compared with the prior art in the pantograph tuber pipe expose in the environment, receive the foreign matter easily and hit the influence of beating with the surrounding environment for damaged air leakage appears in the tuber pipe, leads to the automatic bow that falls of pantograph to increase, influences the driving order, and the lag subassembly in this application has improved the anti ability of beating of tuber pipe, and has reduced external environment and has influenced the tuber pipe, has both protected the tuber pipe, has reduced the swing frequency of the tuber pipe at suspension position again.
