Train bogie bottom storage and isolation device capable of preventing snow accumulation and reducing resistance

Abstract

The invention discloses a train bogie bottom storage and isolation device capable of preventing snow accumulation and reducing resistance. The device comprises main isolation cover plates and middle cover plates; the main isolation cover plates comprise a first main isolation plate and a second main isolation plate; the middle cover plates comprise a first middle isolation plate and a second middle isolation plate; the first middle isolation plate and the second middle isolation plate are symmetrically mounted on the second middle isolation plate in a sliding manner through a middle driving assembly; the first main isolation plate and the second main isolation plate are each provided with a main plate driving assembly; the first main isolation plate and the second main isolation plate moveoppositely or reversely through the main plate driving assemblies; the first main isolation plate and the second main isolation plate are provided with sliding ways matched with wheels of a bogie; the main isolation cover plates and the middle cover plates move oppositely or reversely through the respective driving assemblies and can be switched between a working state and a storage state; accumulated snow and ice in a train bogie area can be reduced; pneumatic resistance borne by the train bogie area is reduced; and the bogie is convenient to overhaul.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicles, in particular to a storage and isolation device at the bottom of a train bogie for snow prevention and drag reduction. Background technique [0002] In the field of rail transit, due to the high speed of vehicles, the requirements for vehicle safety performance are more stringent. For rail vehicles, the safety performance of bogies is particularly important. When high-speed trains are running in snowy weather, the wind will roll up the snow on the track, resulting in serious snow and icing in the bogie area of ​​the train. Snow on the bogie will cause a series of problems: the snow on the elastic suspension will become more and more dense due to the continuous extrusion of the spring, limiting the displacement of the spring, causing the vibration of the train to increase, and affecting the comfort of passengers. The heat on the surface of the motor and gearbox will melt the snow a...

AI Technical Summary

Problems solved by technology

Snow accumulation on the bogie will cause a series of problems: the snow accumulation on the elastic suspension will become more and more dense due to the continuous extrusion of the spring, which limits the displacement of the spring, resulting in aggravated train vibration and affecting the comfort of passengers

The heat on the surface of the motor and gearbox will melt the snow adhered to the surface and condense into ice in the strong cold air, which will increase the suspension quality and axle load of the bogie and deteriorate the dynamic performance of the high-speed train; train brake clips The tongs may also block motion in the case of snow and ice, resulting in accidents, which seriously threatens the operation safety of high-speed trains

[0003] For high-speed trains, on the one hand, the bogie is an important component that contributes to the aerodynamic resistance of the train, which seriously affects the energy consumption of the train; The accumulation of adsorbed snow particles leads to icing, which affects the dynamic performance of trains
