Internal-combustion high-speed motor train unit

Abstract

The invention provides an internal-combustion high-speed motor train unit which comprises a power towing carriage, a motor train unit carriage for carrying passengers as well as a trailer carriage connected with the motor train unit carriage for carrying passengers, wherein the power towing carriage comprises a power towing device and is used for towing the motor train unit carriage and the trailer carriage to run; the motor train unit carriage is connected with the power towing carriage, comprises an electric actuator, and is used for towing the trailer carriage to run through the electric actuator under the towing of the power towing carriage; and the trailer carriage is connected with the motor train unit carriage and runs under the towing of the power towing device and the electric actuator. According to the internal-combustion high-speed motor train unit provided by the invention, by adopting a form of separately arranging the power towing device and the electric actuator, the requirement for large power of the high-speed motor train unit is met, and the axle load is simultaneously reduced so as to enable the internal-combustion high-speed motor train unit to be practical and industrialized possibly, thereby greatly reducing the impact on lines and effectively reducing the construction and maintenance cost of the lines.

Description

technical field [0001] The invention relates to railway vehicles, in particular to an internal combustion high-speed EMU. Background technique [0002] Diesel multiple units are relatively common in all countries in the world at present, but the current diesel multiple units are low-speed, operating speed below 200km / h, according to the international general standard classification, operating speed above 200km / h (including 200km / h) is high-speed EMU Wherein, to realize the high speed of the internal combustion multiple train set, there must be sufficient power (the total power of the internal combustion engine loading is generally at least more than 1000kW), and it is necessary to make the low axle load of both the motor train and the trailer in the multiple train set simultaneously. [0003] In the prior art, high-power (generally above 1000kW) internal combustion engine-driven EMUs are mainly composed of internal combustion locomotives and passenger vehicles, and the power...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, high-power (generally above 1000kW) internal combustion engine-driven EMUs are mainly composed of internal combustion locomotives + passenger vehicles, and the power traction devices such as traction devices and diesel engines are jointly arranged on the internal combustion locomotives. This method is currently widely used in countries all over the world, but the axle of the locomotive is heavy, and the speed of the EMU is limited by the power and axle load of the locomotive
