Embodiment Construction

[0019] Please refer to Figure 1-5 , the embodiment of the present invention provides an EMU, including two end cars 101, the nose cone shells 102 of the two end cars 101 are respectively provided with strip holes 103, and the strip holes 103 are provided with diversion Side strip 104; the guide side strip 104 includes a strip plate 105, the first end of the strip plate 105 is connected with the nose cone housing 102 of the car through a rotating shaft 106, and the strip plate 105 is connected to the driving device 107 connected, the driving device 107 is used to drive the strip plate 105 to rotate around the shaft 106 in the plane where the plate surface of the strip plate 105 is located, so that the strip plate 105 passes through the strip The shaped hole 103 stretches out of the nose cone shell 102 or is received in the nose cone shell 102. When the strip plate 105 stretches out of the nose cone shell 102, the strip plate 105 The length direction of the end car 101 extends...

Abstract

The invention provides a motor train unit. The motor train unit comprises two end trains, train heads nose cone outer shells of the two end trains are respectively provided with a strip-type hole, and guide edge strips are arranged on the positions of the strip-type holes. Each guide edge strip comprises a strip-shaped board, one ends of the strip-shaped boards are connected with the train heads nose cone outer shells through rotating shafts, the strip-shaped boards are connected with a drive device, the drive device is used for driving the strip-shaped boards to rotate around the rotating shafts in a plane where board faces of the strip-shaped boards are located, and therefore the strip-shaped boards can extend out of the train heads nose cone outer shells or be contained in the train heads nose cone outer shells through the strip-type holes. When the strip-shaped boards extend out of the train heads nose cone outer shells, the strip-shaped boards can extend along the length direction of the end trains. The motor train unit can reduce running resistance and power consumption.

Description

technical field [0001] The invention relates to rail vehicle equipment technology, in particular to an EMU. Background technique [0002] As the speed of the EMU continues to increase, the resistance of the EMU will increase significantly. When the speed of the EMU reaches 200km / h, the air resistance accounts for about 70% of the total running resistance. When the speed of the EMU reaches 300km / h, the air resistance Resistance accounts for about 85% of the total running resistance. Most of the energy consumed in the operation of EMUs is used to overcome air resistance. [0003] At present, the shape of the head car of the EMU is the same as that of the tail car, which are similar to the shape of a rotating body. When driving from the starting point to the terminal station, the head car is in front and the tail car is behind. When returning from the terminal station to the original station, the original head The car becomes the tail car, and the original tail car becomes th...
