Abstract

The invention discloses a bottom-arranged power integrated system for a high-speed internal combustion motor train unit. The bottom-arranged power integrated system for the high-speed internal combustion motor train unit comprises a diesel generating set, a diesel auxiliary system, a cooling system, an electronic control system and a mounting frame, wherein the diesel generating set comprises a diesel and a generator; the generator and the diesel are fixed through a connecting flange; the diesel auxiliary system comprises an inlet air filter, an exhaust SCR aftertreatment system, a fuel system and an engine oil system which are arranged on two sides of the diesel generating set; the cooling system comprises a fixed hydraulic pump, a cooling device, an expansion water tank and a fixed hydraulic tank; the diesel generating set and the cooling device are fixed on the mounting frame through elastic rubber dampers; and the mounting frame is hung below a floor of a vehicle through an elastic rubber damper. While axle weight of the bottom-arranged power integrated system for the high-speed internal combustion motor train unit is reduced, passenger carrying space on the vehicle can be utilized to a maximum extent,, and therefore, requirements of high speed passenger transportation are met.

Description

technical field [0001] The invention relates to an undercarriage power integration system for a high-speed internal combustion EMU. Background technique [0002] With the rapid development of high-speed railways, the power-distributed electric multiple units have been widely used. Its characteristics of high power and light axle load make high-speed rail transportation possible. Although the electrification rate of the main railway line is relatively high, the branch railway is still dominated by internal combustion traction. In order to increase the speed of internal combustion traction, the application of high-speed internal combustion and hybrid EMUs with power dispersion is imperative. The existing internal combustion power transmission system has low integration and occupies a large space, which is not conducive to reducing the axle load and effectively utilizing the passenger space on the vehicle. Contents of the invention [0003] In view of the above problems, the...
