High-strength automobile frame

Abstract

The invention discloses a high-strength automobile frame which comprises a left longitudinal beam, cross beam connecting plates and bolts. The left longitudinal beam and a right longitudinal beam are connected through cross beams; a first cross beam, a second cross beam, a third cross beam, a fourth cross beam, a fifth cross beam and a sixth cross beam are sequentially arranged between the left longitudinal beam and the right longitudinal beam from front to back; the inner walls of the left longitudinal beam and the right longitudinal beam are provided with reinforcing ribs; and the cross beam connecting plates are arranged at the portions, connected with the left longitudinal beam and the right longitudinal beam, of the first cross beam, the second cross beam, the third cross beam, the fourth cross beam, the fifth cross beam and the sixth cross beam. According to the automobile frame, traditional rivet frames are changed, and the bolts are adopted for fastening, are better in shock resistance and convenient to use, and have the unique reusability; and hot rolling low alloy high strength steel plates are used for the automobile frame, on the premise that the rigidity is ensured, the thickness of the steel plates can be reduced, the weight of the automobile frame can be reduced, the bearing capacity of the automobile frame can be improved, and the service life of an automobile can be prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile frame, in particular to the automobile frame. Background technique [0002] The frame is a frame structure spanning the front and rear axles of the car, commonly known as the girder, and is the base of the car. It is generally composed of two longitudinal beams and several beams, and is supported on the wheels through the suspension device, front axle, and rear axle. The frame must have sufficient strength and rigidity to withstand the load of the car and the impact from the wheels. The function of the frame is to support and connect the various assemblies of the car, so that each assembly maintains a relatively correct position, and bears various loads inside and outside the car. [0003] The traditional automobile girder and fixed various external assemblies are connected by willow joint or welding method. When this connection method falls off or is damaged, professional tools are needed to...

AI Technical Summary

Problems solved by technology

[0003] The traditional automobile girder and fixed various external assemblies are connected by willow joint or welding method. When this connection method falls off or is damaged, professional tools are needed to help replace it, which has certain limitations. The frame longitudinal beam Holes sometimes need to be drilled in the stringers to install certain components or assemblies, these holes can cause stress concentrations that reduce the strength of the frame rails and cause cracking
