Special vehicle body with double bearing structures

Abstract

The invention relates to a special vehicle body with double bearing structures. A special vehicle body with double bearing structures comprises a vehicle frame and a vehicle shell, the vehicle frame comprises a cab bearing part and a loading bearing part, the cab bearing part comprises cab longitudinal beams, cab cross beams and cab stand columns, and the cab longitudinal beams and the cab cross beams on the same layer define a closed ring. The cab cross beams and the cab stand columns which are vertically opposite define closed rings, the cab longitudinal beams and the cab stand columns which are vertically opposite define closed rings, and all the closed rings form a full-bearing truss structure. The loading bearing part comprises a bearing main beam extending front and back, and a transition connecting structure is arranged between the bearing main beam and the cab bearing part. The upper loading bearing part further comprises upper loading beams and upper loading stand columns, the vehicle shell comprises a ship shell plate frame structure arranged outside the upper loading bearing part, an upper loading area is arranged on the upper side of the upper loading bearing part, and a buoyancy cabin located on the lower side of a loading cabin is defined by the ship shell plate frame structure.

Description

technical field [0001] The invention relates to the field of special vehicles, in particular to a special vehicle body with a double bearing structure. Background technique [0002] Different from ordinary vehicles, some special vehicles need to meet both land and water conditions. In order to achieve the above requirements, the special vehicle needs to be equipped with vehicle parts (such as tires, steering wheel, etc.) complex. According to the design requirements of the hull, the outer shell needs to adopt a plate frame structure. In order to meet the load requirements on land, the plate frame must adopt thick plates. However, the weight of the thick plates is heavy, which will seriously exceed the weight of the special vehicle, which will directly affect the water quality of the equipment after entering the water. Safety. If the structure of the car is used, in order to meet the water seal, a shell needs to be arranged outside the lower part of the frame to enclose th...

Problems solved by technology

[0005] The object of the present invention is to provide a special vehicle body with a double load bearing structure to solve the problem that the special vehicle body is located at the lower side of the upper loading area in the prior art. The internal space of the buoyancy chamber is small and the technical problem is not convenient for maintenance
