Abstract

The invention provides a motor train unit train body and a motor train unit. The motor train unit train body comprises a train bottom, side walls, end walls and a roof. The bottoms of the side walls are connected with the train bottom, and the ends of the side walls are connected with the end walls. The roof comprises movable top frames and driving devices, the driving devices can drive the movable top frames to be opened and closed, a chamber is jointly defined by the train bottom, the side walls, the end walls and the roof when the movable top frames are in a closed state, and the chamber is exposed when the movable top frames are in an opened state. The motor train unit train body is simple in structure, safe, reliable and convenient to operate; besides, modularized installation of large internal equipment is convenient.

Description

technical field [0001] The invention relates to a rail transit train body, in particular to an EMU body and an EMU. Background technique [0002] combine figure 1 and figure 2 As shown, the existing EMU car body usually includes a car bottom 1, a side wall 2, an end wall (not shown) and a car roof 8, wherein the top of the side wall 2 is connected to the car roof 8, and the bottom of the side wall 2 is connected to the car roof. The bottom 1 is connected, and the two ends of the side wall 2 are respectively connected with the end wall, so that the bottom 1, the side wall 2, the end wall and the roof 8 are jointly enclosed to form a chamber. [0003] The connection mode between the roof 8 and the side wall of the above-mentioned EMU car body is mainly welding, and the welding position 9 is as follows: figure 2 shown. However, the EMU car body in this setting method has the following defects: 1) The welding cycle between the roof 8 and the side wall is long, and the weld...
