Power source centralized type internal combustion power dispersing type motor train unit

Abstract

The invention provides a power source centralized type internal combustion power dispersing type motor train unit. The power source centralized type internal combustion power dispersing type motor train unit comprises at least one power source car, at least one motor train and at least one trailer, wherein an diesel generating set is arranged on the power source car, the power source car and the trailer are respectively provided with an unpowered bogie, the motor train is provided with a traction system and a power bogie which are electrically connected with each other, the power source car, the motor train and the trailer are connected together through a motor train unit connector, and the diesel generating set is electrically connected with the traction system through the motor train unit connector. By setting the diesel generating set in the power source car and setting the traction system in the motor train, the diesel generating set and the traction system are distributed in the different cars so as to realize the layout of centralizing a power source but dispersing power; the axle weight of each car is lightened on the whole, and the demands of operating on a high speed railway is satisfied.

Description

technical field [0001] The invention relates to railway vehicles, in particular to a centralized power source internal combustion power decentralized EMU. Background technique [0002] Order No. 34 of the Ministry of Railways of the People's Republic of China, which came into effect on February 1, 2013, clearly stipulates that high-speed railways are newly designed and operated 250km / h (including reserved) and above EMU trains, and the initial operating speed is not less than 200km / h. For passenger-dedicated railways, the axle load of high-speed trains is no more than 17t, and the marshalling is no more than 16 vehicles. However, the EMUs in the prior art usually adopt electric multiple units, and the electric multiple units adopt the power grid to receive electricity, and the axle load is basically below 15t. However, the EMUs of traditional DMUs include power sources, control systems, traction systems, cooling systems, etc., and the axle load of DMUs is generally above 20...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to provide a centralized power source internal combustion power decentralized EMU, which solves the defect that the internal combustion EMU in the prior art cannot run on passenger high-speed railways, and realizes the reduction of power source centralized internal combustion power. The axle load of decentralized EMUs meets the requirements for running on high-speed railways
