Abstract

The invention discloses a chassis assembly and a vehicle body comprising the chassis assembly, the chassis assembly comprises a middle beam assembly, two end beam assemblies arranged on two sides of the end part of the middle beam assembly and two sleeper beam assemblies arranged on the middle beam assembly, and the two sleeper beam assemblies are located between the two end beam assemblies; each sleeper beam assembly comprises two sleeper beam bodies symmetrically arranged on the two sides of the middle beam assembly, a rotating shaft mounting base is arranged at the top of each sleeper beam body, and the rotating shaft mounting bases are used for being rotationally connected with rotating shafts arranged at the bottoms of the carriage assemblies so as to vertically limit and transversely limit the carriage assemblies; a lower limiting block assembly is further arranged on the middle beam assembly and located between the two sleeper beam bodies in the same set, and the lower limiting block assembly is used for being matched with the bottom of the carriage assembly so as to longitudinally limit the carriage assembly. The self-weight of the chassis can be reduced, the transportation energy consumption can be reduced, the transportation benefit can be improved, the efficiency of tipping unloading operation can be improved, and the safety of tipping operation can be improved.

Description

technical field [0001] The invention relates to the technical field of the underframe of a railway self-tipping car, in particular to an underframe composition and a car body comprising the underframe composition. Background technique [0002] The car tilting power system of the existing railway self-tipping car is installed on the bottom frame, and the tilting power system mounting bracket is provided on the side of the middle beam of the bottom frame. Therefore, the chassis has a large bearing capacity, heavy self-weight, complex structure, high manufacturing, application, and maintenance costs, which increases the transportation energy consumption and reduces the transportation economic benefits accordingly. [0003] In the tipping power system of the existing self-tipping vehicle, the upper hinge point of the tipping cylinder is at the bottom of the underframe of the carriage, and the lower hinge point is at the side of the underframe. In the process of tipping and unlo...
