Bogie bilge plate assembly, bogie and rail vehicle

Abstract

The embodiment of the invention provides a bogie bilge plate assembly, a bogie and a railway vehicle, and the bogie bilge plate assembly comprises a bilge plate frame which extends in the length and width directions of the bogie and is used for being arranged below the bogie, at least one access door mounting hole defined by the bilge plate frame, and an access door arranged in the access door mounting hole; one side of the access door is rotationally connected with the bilge plate frame, and the other opposite side of the access door is locked and connected with the bilge plate frame through a locking mechanism. According to the bogie bilge plate assembly, the bogie and the railway vehicle, the bogie can be protected, gravel, particulate matter, sundries and the like on the ground are prevented from entering the bogie and colliding with pipelines, electric wires and other parts of the bogie, the service life of all the parts is prolonged, and the reliability and the running safety are improved. In addition, the bogie can be conveniently maintained and overhauled through the access door which can be opened and locked.

Description

technical field [0001] The present application relates to rail vehicle running technology, in particular to a bogie bottom deck assembly, a bogie and a rail vehicle. Background technique [0002] Rail vehicles are an important transportation link connecting cities, and have gradually become the main means of transportation in cities. Rail vehicles are also the main carrier for cargo transportation. A rail vehicle mainly includes: a car body and a bogie arranged under the car body. The bogie is used to carry the car body and realize the running and steering functions. [0003] The bogie is arranged at the bottom of the car body, close to the ground. When the vehicle is running at high speed, sand, gravel, particles, sundries, etc. on the ground are easily carried by the airflow into the interior of the bogie, and hit the pipes, wires and other components of the bogie, causing pits on the surface of the components, which will affect their strength and shorten their strength. ...

AI Technical Summary

Problems solved by technology

When the vehicle is running at high speed, sand, gravel, particles, sundries, etc. on the ground are easily carried by the airflow into the interior of the bogie, and hit the pipes, wires and other components of the bogie, causing pits on the surface of the components, which will affect their strength and shorten their strength. Service life, serious cases will affect driving safety

In addition, the various parts of the bogie will also generate a certain amount of wind resistance to the airflow to a certain extent, and will generate greater noise when the driving speed is fast.
