Car body for preventing snow accumulation and icing of a bogie

Abstract

The invention discloses a car body for preventing snow accumulation and icing of a bogie, comprising a bogie under the car body, a first-stage air deflector is arranged in front of the bogie along therunning direction of the car body, and the first-stage air deflector is installed on the bottom plate of the car body; The primary air guide plate is provided with a fixed mounting surface for mounting and a air guide surface for guiding the wind and snow flow at the bottom of the vehicle body to the lower part of the bogie, the virtual plane of the air guide surface extends downward below the bottom of the wheels of the bogie, and the secondary air guide plate is cooperatively provided on the bogie. The primary air guide plate is provided with a fixed mounting surface for mounting and guiding the snow flow at the bottom of the vehicle body to the lower part of the bogie. The device can effectively guide the air flow trend at the bottom of the train, Reduce snow intake in the bogie area,The motion height of snow flakes in bogie area is controlled to weaken the scouring effect of snow flakes on the bottom equipment of train bogie, so as to avoid snow accumulation on train bogie in operation, to ensure that the dynamic performance of bogie will not be deteriorated due to snow accumulation, and to improve the safety and transportation efficiency of high-speed train in snow-rich weather.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a train body capable of preventing bogies from snow accumulation and icing in the operating environment of heavy snow in winter. Background technique [0002] When high-speed trains are running in snowy weather, the train wind will roll up the snow on the track, resulting in serious snow and icing in the bogie area. 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 adhered to the surface and condense into ice in the strong cold air, which increases the suspension quality and axle load of the bogie and deteriorates the dynamic performance of the high-speed train. In addi...

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 increases the suspension quality and axle load of the bogie and deteriorates the dynamic performance of the high-speed train

In addition, the movement of train brake calipers may be blocked in the case of snow and ice, resulting in accidents, which seriously threatens the operation safety of high-speed trains

[0003] At present, most high-speed trains are not equipped with anti-bogie snow and icing devices, resulting in extremely serious snow and icing in the bogie area when high-speed trains are running in alpine regions.

A small number of high-speed trains install rubber capsules on the bottom plate of the equipment cabin to optimize the flow state in the bogie inlet area to a certain extent, but the rubber capsules installed in the exit area will deteriorate the flow state at the bogie exit. The "snow pocket" phenomenon occurs at the bottom of the car body

Moreover, the railway lines in the alpine regions of our country are all long-crossing lines, and the one-way running time of the trains is relatively long, resulting in serious snow and ice on the bogies of the rubber capsule trains.
