The invention belongs to the technical field of railway wagons, and particularly relates to a concave bottom frame and a railway concave bottom vehicle. The concave bottom frame comprises two end armassemblies and bearing beam assemblies, the two end arm assemblies are oppositely arranged in the longitudinal direction, the bearing beam assemblies are arranged between the two end arm assemblies, and the ends of the bearing beam assemblies are connected with the end arm assemblies at the same end; the end arm assemblies and the bearing beam assemblies are both of a non-closed cavity structure with the bottom open, and an air braking system is arranged in a non-closed cavity structure at the bottom of the concave bottom frame. The concave bottom frame has the characteristics of simple and economical structure and simplicity and convenience in production and manufacturing, facilitates arrangement, installation, debugging and maintenance of a single brake cylinder and a single brake adjuster brake system, enables brake to be safer and more reliable, and is high in practical performance.
Description
technical field [0001] The invention belongs to the technical field of railway wagons, in particular to a concave bottom frame and a railway concave bottom car. Background technique [0002] Railway concave-bottomed flat cars are mainly used to transport super-high cargo, and play a pivotal role in the transportation of special railway cargo. [0003] At present, the four-axis railway concave-bottom flat car with a load of more than 40t, due to the heavy load, in order to improve the rigidity of the concave bottom frame, the concave bottom frame is generally designed as a box-shaped fully enclosed cavity structure, and the whole vehicle adopts double brakes. The braking system of the cylinder and the double brake adjuster increases the number of accessories of the braking system, reduces the reliability of use, and increases the manufacturing cost. At the same time, the brake system adopts double brake cylinders and double brake regulators, and the brake cylinders and brake...
