Joggling type vehicle bottom plate assembly

Abstract

The invention relates to a joggling type vehicle bottom plate assembly which comprises edge beams, longitudinal beams and transverse beams. The joggling type vehicle bottom plate assembly is characterized in that the upper parts of the edge beams and the longitudinal beams are provided with planes; one side edge of the edge beams is provided with a joggling groove structure along the length direction, and both side edges of each longitudinal beam are provided with joggling groove structures along the length direction; the edge beams are connected with the longitudinal beams by a joggling groove along the transverse direction of a vehicle body so as to form a plane on the upper surface or the edge beams are connected with the longitudinal beams and the longitudinal beam is connected with the longitudinal beam in such a way that both side edges are provided with transition connecting plates in the joggling groove structure by the joggling groove along the transverse direction of the vehicle body so as to form the plane on the surface; and the transverse beams are connected with the edge beams and the longitudinal beams. The invention prevents the welding deformation of the bottom plate assembly and eliminates welding stress, and the strength and the working reliability of the bottom plate assembly are not influenced by welding, particularly the vehicle bottom plate made of an aluminum magnesium alloy material has more obvious effect; no harmful gas is generated in the assembly process of the bottom plate assembly, thereby being beneficial to environmental protection; the assembly process is simple, the production efficiency is high, and the manufacture cost is reduced.

Description

technical field [0001] The invention relates to a mortise-joint vehicle floor assembly, in particular to a floor assembly device for automobile carriages, automobile trailers and train carriages, belonging to the field of vehicle components. Background technique [0002] At present, the floor assemblies of automobile carriages, automobile trailers, and train carriages are basically made of metal materials, and are formed by welding side beams, longitudinal beams, cross beams, and floor plates. Side beams, longitudinal beams, and beams form a frame structure welded under the bottom plate to support and strengthen the bottom plate. The main disadvantage of this welding structure is: during the welding process, the floor assembly is prone to welding deformation and welding stress, which affects the strength and working reliability of the floor assembly, especially the vehicle floor made of aluminum and magnesium alloy materials , the impact of welding is even worse; during the...
