High speed rail vehicle capable of adjusting pressure on ground

Abstract

The present invention relates to a high-speed track traffic vehicle, mainly formed from high-speed track vehicle and track beam. It is characterized by that when the vehicle is running on the overhead track beam at high speed, the drive friction pressure required for all the drive wheels in the vehicle can be provided by springs placed in the vehicle and rolling device capable of regulating pressure, and the electromagnetic suspended electromagnetic iron placed in the vehicle and suspended supporting track on the track beam are interacted between them, so that the carriage can be suspended on the track beam, and can be driven by the driving wheel in vehicle and can be run at high-speed.

Description

technical field [0001] The invention relates to a high-speed rail vehicle, in particular to a high-speed rail vehicle with adjustable ground pressure by using its own hydraulic device to increase and adjust the frictional pressure between the wheels and rails of the high-speed rail vehicle. Background technique [0002] The friction pressure (adhesion force) between the wheels and the rails of the current high-speed rail vehicles mainly depends on the self-weight of the traction locomotive. As the speed of the train increases, the friction pressure between the wheels and the rails also decreases, causing the speed to be affected. However, the driving safety of the vehicle is greatly affected due to the reduction of the friction pressure. Although the friction pressure between the wheel and the rail in the "Intercity High-speed Light Rail Transit" with the application number 01141380.8 has been greatly improved, However, because the setting of the door frame and the top rail ...

Problems solved by technology

[0002] The friction pressure (adhesion force) between the wheels and the rails of the current high-speed rail vehicles mainly depends on the self-weight of the traction locomotive. As the speed of the train increases, the friction pressure between the wheels and the rails also decreases, causing the speed to be affected. However, the driving safety of the vehicle is greatly affected due to the reduction of the friction pressure. Although the friction pressure between the wheel and the rail in the "Intercity High-speed Light Rail Transit" with the application number 01141380.8 has been greatly improved, However, because the setting of the door frame and the top rail on the track beam objectively causes the vehicle to be inconvenient for cargo transportation, and the door frame and the top rail also increase the investment of the line; and the application number is "High-speed straddle rail vehicle" In the vehicle, the driving friction pressure of the vehicle is provided by the pressure device installed under the conductive wheel in the vehicle. Since the space under the conductive wheel is small, the pressure device is also small, and the friction pressure provided to the driving wheel in the vehicle is also small, which is difficult Guarantee the high frictional pressure required when the vehicle runs at high speed; at the same time, because it is driven by a linear motor in the currently applicable maglev train, the investment in its line is large and cannot be widely used
