Described sleeper beam near the two ends of described central sill, and is fixedly connected with the end flat segments of described curb girder.
The framework end face that described end carriage, curb girder, crossbeam, sleeper beam and beam form lays the base plate that steel plate forms described car body.
Described side face of wall is fixedly connected with multiple column for increasing described side wall intensity, and the bottom of column described in each is all fixedly connected with described curb girder; Described side face of wall above the flat segments of described curb girder end is fixedly connected with the strength beam of multiple horizontal direction.
Described end face of wall is fixedly connected with the strength beam of multiple horizontal direction.
The present invention is owing to taking above technical scheme, and it has the following advantages: 1, the present invention is owing to being arranged to concave configuration at each curb girder centre portion of underframe, and jointly forms the lower concave plane of underframe by concave configuration, some crossbeams, central sill bottom and base plate; Concave shape is arranged to each curb girder concave configuration corresponding car body both walls centre portion; Therefore vehicle body volume is increased.2, the present invention is due to each curb girder of underframe arranging two acclivitous transition structures, jointly form acclivitous two intermediate incline of underframe by two transition structures, some crossbeams and base plate, two intermediate incline of underframe underframe can be made to avoid contacting with car body bogie truck and increase vehicle body volume, improve car body stressed, reduce body construction sudden change.3, the present invention is formed by fixedly connecting by an end wall panel, some cross bands due to each headwall, and each headwall is overall facade shape; Therefore, it is possible to improve headwall strength and stiffness.4, the present invention arranges a brake system in the center bottom of underframe, and brake system is fixedly connected on central sill bottom, and therefore the present invention can increase vehicle body volume.5, body system of the present invention is simple, is convenient to manufacture, and has higher economic and practical.
