Abstract

The invention discloses a split-type hydraulic transmission power system for an internal-combustion motor train unit. The split-type hydraulic transmission power system comprises a diesel engine, a hydraulic transmission tank system, an auxiliary system, a cooling system, a mounting frame and an electric control box; and the mounting frame comprises a first frame and a second frame, the diesel engine and the auxiliary system are integrated on the first frame, and the hydraulic transmission tank system is fixed to the second frame. According to the split-type hydraulic transmission power systemfor the internal-combustion motor train unit, a diesel engine system, the hydraulic transmission tank system and a cooling device are integrated independently and suspended on the lower part of the train floor and mounted at the train top correspondingly, the demands of the high-speed internal-combustion motor train unit for traction power are met, meanwhile, the space below the motor train unitand the space at the top of the motor train unit are utilized reasonably, and the mounting requirements of the power system of the motor train unit are met.

Description

technical field [0001] The invention relates to the technical field of diesel trains, in particular to a split hydraulic transmission power system for diesel trains. Background technique [0002] Due to its simple structure, high efficiency, and low maintenance costs, hydraulic transmission is widely used in the field of international diesel trains. It is used in high-power hydraulic transmission boxes and cooling systems for high-speed trains. In the prior art, the hydraulic transmission case, the diesel engine and the cooling system are respectively installed on the EMU, which has a low integration level and takes up a large space, which is not conducive to reducing the axle load and effectively utilizing the space. Contents of the invention [0003] In view of the above problems, the present invention researches and designs a split type hydraulic transmission power system for a diesel multiple unit. The technical means adopted in the present invention are as follows: ...
