Description
Technical Field
The invention relates to a railway rolling stock, in particular to a side wall structure for a depressed center low-floor vehicle.
Background
From the perspective of maximizing economic benefits, the longer the length of the railway wagon and the wider the inner width of the side wall, the higher the adaptability of loading goods. For example, a special railway transport truck can load longer trucks or can increase the loading quantity, a certain gap exists between the side surface of the truck and the side wall of the railway wagon, so that the truck can be guaranteed to run smoothly or be lifted without collision during loading and unloading, and the lower the loading surface of the railway wagon, the higher the height of the truck can be loaded.
However, GB146.1 "standard gauge railroad rolling stock clearance" specifies the maximum allowable manufacturing width of the railway freight car, the minimum height of the car and the maximum loading height of the freight, and as the length of the car is longer, the maximum allowable manufacturing width is smaller, and there is a close relationship between the length, width and height of the car. On the premise that the length of the vehicle is optimal and the outer width of the vehicle reaches the maximum allowable manufacturing width, the inner width of the vehicle can be increased only from the structural angle of the side wall of the vehicle.
The concave bottom large-wheelbase railway wagon is more and more widely applied due to wide adaptability. For a concave bottom vehicle, the height of a concave bottom surface for loading cargoes is just higher at an inclined plane part with smaller vehicle clearance, and the inclined plane part is also a connecting part of a side wall and an underframe, and in the prior art, the connecting part of the side wall and the underframe occupies larger width in the vehicle, so that the cargo loading adaptability is influenced. Therefore, it is necessary to provide a structure for maximizing the inner width of the side wall while satisfying the strength and clearance requirements of the railway freight car.
