Embodiment 1

[0042] figure 1 A schematic diagram of the power system.

[0043] like figure 1 As shown, the power system 10 of this embodiment is used for a rail vehicle, and includes: a power device 110 , a plurality of driven devices 130 and a transmission device 120 . The output end of the power device 110 is connected to the input end of the transmission device 120 , and the output end of the transmission device 120 is connected to the driven device 130 .

[0044] Specifically, the transmission device 120 includes a multi-stage gear train, and the multi-stage gear train has one input end and multiple output ends, such as four output ends. The output end of the power device 110 is connected to the input end of the multi-stage wheel train, and each output end of the multi-stage wheel train is respectively connected to the input end of a driven device 130 . The power output by the power device 110 is transmitted to each driven device 130 through the transmission of the multi-stage gear ...

Embodiment 2

[0049] figure 2 is the front view of the rail locomotive; image 3 for figure 2 Partial enlarged view of position A in middle; Figure 4 for figure 2 The perspective view of the locomotive looking down on the middle rail; Figure 5 for Figure 4 Partial enlarged view of position B in middle.

[0050] like Figure 2-Figure 5 As shown, the rail locomotive of this embodiment is provided with a power room 1, a driver's cab 2 and a brake room 3 sequentially from left to right. The power system 10 as described above is installed in the power room 1 .

[0051] The rail locomotive of this embodiment is driven by connecting a multi-stage wheel train with multiple output ends between the power device 110 and a plurality of driven devices 130, and the number and speed of power output can be adjusted through the number of stages of the wheel train , very convenient and flexible. Moreover, the gear transmission also reduces the energy loss in the transmission process, which mak...

Abstract

The invention provides a power system and a rail locomotive. The power system is used for the rail locomotive and comprises a power device, a plurality of driven devices and a transmission device, wherein the transmission device comprises a multi-stage gear train with a plurality of output ends; the output end of the power device is connected with the input end of the multi-stage gear train; and the input ends of the plurality of driven devices are respectively connected with one output end of the multi-stage gear train. The rail locomotive comprises a power room, a cab and a brake room which are sequentially arranged, wherein the power system is installed in the power room. According to the power system and rail locomotive provided by the invention, by connecting the multi-stage gear train with the plurality of output ends between the power device and the plurality of driven devices so as to carry out transmission, power output is more flexible.

Description

technical field [0001] The invention relates to a power system and a rail locomotive. The power system is used for the rail locomotive and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] The power system is the heart of the rail locomotive, and the traction provided by the power system can make the rail locomotive work normally. [0003] The power system of the existing rail locomotive includes a diesel engine, an electromagnetic clutch, a belt, an alternator and an air compressor; the input end of the alternator is connected with the free end of the diesel engine through an electromagnetic clutch; the input end of the air compressor is connected through a belt Connect to the free end of the diesel engine. [0004] However, because the existing power system is driven by a belt and an electromagnetic clutch, the power output is not flexible enough. Contents of the invention [0005] The invention provides a power system and a ra...
