Embodiment Construction

[0016] Such as figure 1 , figure 2 As shown, a passenger diesel locomotive with direct power supply for trains, the locomotive is divided into upper and lower parts. The middle of the lower part is a fuel tank 23, and the fuel tank 23 adopts a load-bearing type, which can effectively reduce the weight of the car body. The fuel tank is provided with battery case 24, total wind cylinder 25 and power supply control cabinet two 26. A front bogie 33 and a rear bogie 34 are respectively arranged on the vehicle frames at the two ends below. The front bogie 33 and the rear bogie 34 are A1A axle-type frame-suspended quasi-high-speed bogies. The lower unsprung weight can greatly reduce the wheel-rail force when the locomotive is running, and improve the service life of the wheels and rails.

[0017] The upper car body is divided into six chambers by five partitions, which are the first driver's cab 1, the electrical room 43, the power room 44, the cooling chamber 45, the auxiliary r...

Abstract

The invention relates to the technical field of a diesel locomotive, and particularly relates to a diesel locomotive for direct power supply passenger transport of a train. The locomotive is divided into an upper part and a lower part; the locomotive body at the upper part is divided into six chambers by five partition walls; the six chambers respectively are a first cab, an electric room, a power room, a cooling room, an auxiliary room and a second cab orderly arranged from front to back; steering bogies are arranged at two ends of the lower part; a fuel tank is arranged in the middle; a storage battery and a main air reservoir are arranged on the fuel tank; and the front steering bogie and the rear steering bogie at the lower part adopt suspended high-speed bogies. The diesel locomotive for direct power supply passenger transport of the train adopts a dual-cab structure, is integrated with two sets of direct power supply systems for passenger trains; one set of power supply system is in primary and auxiliary power generators which are in coaxial serial arrangement, and the auxiliary power generator provides 400kW of power supply output power to the auxiliary train; the other set of power supply system is an independent power supply diesel generating set, and also can provide 400kW of power supply output power; and the maximal power supply output power of the entire locomotive can achieve 800kW. The diesel locomotive disclosed by the invention is high in reliability, good in economical efficiency, and strong in applicability.

Description

technical field [0001] The invention relates to the technical field of diesel locomotives, in particular to a passenger diesel locomotive with direct power supply for trains. Background technique [0002] At present, the traction power of domestic passenger trains is divided into electric locomotives and internal combustion locomotives. When diesel locomotives are used for traction, there are two ways to realize the power supply of passenger trains. The direct-powered diesel locomotive with multiple locomotives provides power for passenger trains. Above-mentioned two kinds of ways all can't realize that single locomotive is full-load power supply for whole passenger train. Contents of the invention [0003] In order to overcome the deficiencies of the existing technology, the invention provides a passenger diesel locomotive with direct power supply for trains. [0004] The technical solution adopted by the present invention to solve the technical problem is: a direct pow...
