Embodiment 1

[0050] Such as Figure 1-16 As shown, the invention discloses an underframe end integration device, which can be used for various EMUs or trains. Wherein, the bottom frame end integration device includes a dirt box 1 and a dirt box lifting point 3 .

[0051] The dirt box 1 is a special-shaped dirt box, which is used to hold the dirt. Specifically, the dirt box 1 is connected with the dirt discharge pipeline on the EMU, and the dirt discharge pipeline is used for toilets, washrooms and water heaters, etc. waste discharge.

[0052] Dirt discharged from the dirt discharge pipe can enter the dirt tank 1 . The structure of the dirt box 1 is a special-shaped structure, which is located at the bottom of the vehicle underframe, and is attached to the inner wall of the space for holding the dirt box 1 formed by the end part 2 of the vehicle underframe. And when the dirt box 1 is installed on the vehicle underframe end 2, the dirt box 1 can be attached to the vehicle underframe end 2...

Embodiment 2

[0056] In the second embodiment provided by the present invention, the structure of the bottom frame end integration device in this embodiment is similar to that of the bottom frame end integration device in the first embodiment. the difference.

[0057] In this embodiment, the present invention specifically discloses that the dirt tank 1 surrounds the dirt tank lifting point 3 . Specifically, the dirt box lifting point 3 is arranged in the middle area of ​​the dirt box 1, which has a compact structure and saves space.

[0058] Further, the present invention discloses that the integrated device at the end of the chassis further includes a buckle connector 4 and a mounting bracket 5 . The buckle-type connector 4 is used to connect the high-voltage cable 6 between the adjacent cars of the EMU and the bridge line 7 passing through from the outside of the EMU. There are several snap-in connectors 4 , which are installed on the mounting frame 5 , which is mounted on the end portion...

Embodiment 3

[0078] The present invention provides an EMU, including the bottom frame end integration device in any one of the above embodiments.

Abstract

The invention discloses a motor train unit and a chassis end integration device thereof. The chassis end integration device comprises a dirt box and dirt box lifting points, wherein the dirt box is aspecially-shaped dirt box and used for containing dirt, and when installed at the end of a vehicle chassis, the dirt box can be attached to the end of the vehicle chassis; and the dirt box lifting points and a traction beam at the end of the vehicle chassis are integrally formed, and the dirt box is installed at the end of the vehicle chassis through the dirt box lifting points. Due to the fact that the dirt box containing the dirt is of a specially-shaped structure and the dirt box can be attached to the end of the vehicle chassis when installed at the end of the vehicle chassis, the containing space of the dirt box is enlarged; and in addition, the dirt box lifting points and the traction beam of the vehicle chassis are integrally formed, and the situation that the direction strength oflongitudinal force transmission of the vehicle chassis becomes poor due to the fact that holes are formed in the traction beam is avoided. In conclusion, the containing space of the dirt box is enlarged, and the situation that the direction strength of longitudinal force transmission of the vehicle chassis becomes poor is avoided.

Description

technical field [0001] The invention relates to the technical field of railway transportation, in particular to an EMU and an integrated device for the bottom frame end thereof. Background technique [0002] With the development of high-speed EMU operations, the daily use frequency of EMUs has increased, and the utilization rate of water supply and sanitation systems has increased. At present, most of my country's EMU toilets are arranged at the end of the vehicle underframe (each compartment), and the dirt box for collecting dirt is square, and the dirt box is installed by offering hanging holes on the vehicle underframe. Due to the narrow space at the end of the vehicle underframe, the storage space for the dirt box is small, and the opening of hanging holes on the vehicle underframe leads to the deterioration of the direction strength of the vehicle underframe for transmitting longitudinal force. [0003] Therefore, how to increase the storage space of the dirt tank and ...
