Vehicle frame, manufacturing method thereof, and vehicle with vehicle frame

Abstract

The invention discloses a vehicle frame, a manufacturing method thereof, and a vehicle with the vehicle frame. The vehicle frame comprises a main body structure, the main body structure comprises a first transverse rod, a second transverse rod, a first longitudinal rod and a second longitudinal rod, the two ends of the first transverse rod are connected with the upper end of the first longitudinal rod and the upper end of the second longitudinal rod respectively, and the two ends of the second transverse rod are connected with the lower end of the first longitudinal rod and the lower end of the second longitudinal rod respectively. The first transverse rod, the second transverse rod, the first longitudinal rod and the second longitudinal rod each comprise a steel wire, the outer side of the main body structure is coated with alloy, and the main body structure is integrally formed. According to the steel wire and the alloy wrapping the outer side of the main body structure, the problems that a single material is insufficient in strength, poor in fatigue resistance and the like are solved and overcome, the strength requirement of the main body structure is met, and meanwhile the requirement for vehicle light weight is met. In addition, due to the integrated design, the problem that the bearing capacity is reduced due to welding joints is solved.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a vehicle frame, a preparation method and a vehicle with the same. Background technique [0002] Most of the chassis frames of existing off-road vehicles adopt steel frames, which are manufactured by stamping and welding, and have problems such as heavy weight, low fatigue performance, and poor corrosion resistance. In response to these problems, some existing manufacturers have designed all-aluminum frames. The main body of the frame is still welded in sections. Although the weight reduction effect is remarkable, it faces poor mechanical properties, serious welding defects, and poor overall fatigue resistance of the frame. And other problems, so it is difficult to apply on a large scale at present. Contents of the invention [0003] Aiming at the problems in the prior art that the steel frame is heavy and the welding strength of the bracket is insufficient; the s...

Problems solved by technology

[0003]Aiming at the problems in the prior art that the steel frame is heavy and the welding strength of the bracket is insufficient; the strength of the segmented welded aluminum frame is insufficient and the fatigue performance is poor. The invention provides a vehicle frame, a preparation method and a vehicle having the same. The vehicle frame not only satisfies the requirement of lightweight vehicles, but also avoids the problems of poor fatigue resistance and insufficient strength of the all-aluminum vehicle frame
