Embodiment Construction

[0016] Refer to attached figure 1 , 2 , 3, 4, the present invention is made up of edge beam 1, longitudinal beam 2, beam 3, transition connecting plate 4. The side beam 1, the longitudinal beam 2, and the transition connecting plate 4 are connected together by tongue and groove along the transverse direction of the vehicle body, and their upper surfaces form a plane. Part of the side beam 1 can be used as the bottom plate. There is a tenon and groove 11 on one side of the side beam 1. There is a tenon and groove 12 for installing the hinge of the carriage on the side beam 1, and a tenon and groove 13 for installing the shackle. The side beam 1 has a limit beam 3 degrees of freedom There are tenon grooves 21 on both sides of the longitudinal beam 2, a part of the longitudinal beam 2 can be used as a bottom plate, and the web of the longitudinal beam 2 has slot holes; the transition connecting plate 4 has tenon grooves 41 on both sides. The connection relationship of each piec...

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...
