Problems solved by technology
[0002] At present, during the R&D and design process of straddle-type monorail trains, since the bogie structure requires a large installation and operating space, the bogie proposes a large space restriction area for the vehicle body traction beam
The solution in the prior art is to optimize the structure of the bogie and reduce the space occupied by the bogie. However, due to the special operating conditions of the existing straddle-type monorail trains, the bogie cannot meet the requirements of the operating conditions. make more drastic changes
Therefore, in the existing straddle-type monorail trains, it is difficult to meet the space restriction requirements of the bogie on the traction beam under the premise of satisfying the structural strength of the traction beam

The invention relates to the technical field of railway vehicles, and provides a traction beam composition structure and a railway vehicle. The traction beam composition structure comprises a tractionbeam, a stop beam and a buffer beam, the traction beam comprises two traction beam bodies arranged in a spaced mode, the first end of each traction beam body is provided with a buffer beam connector,and the second end of each traction beam body is provided with a stop beam connector; the stop beam comprises a first inserting plate, a second inserting plate and a connecting end plate, a stop beaminserting groove with an opening facing the traction beam is formed among the first inserting plate, the connecting end plate and the second inserting plate, and all stop beam connectors are connected with the stop beam inserting groove in an inserted mode. A buffer beam inserting groove is formed in the side, facing the traction beam, of the buffer beam, and the buffer beam connectors are connected with the buffer beam inserting groove in an inserted mode. On the premise that the requirement for the structural strength of the traction beam is met, the occupied space of the traction beam is saved to the maximum degree, so that the maximum installation and operation space is provided for a bogie structure of the straddle type monorail train.
