Description

Technical Field

[0001] The invention relates to a frame device, a use method and applications thereof, in particular to a frame device based on a sheet frame, a use method and applications thereof. Background Art

[0002] The frame is a frame structure that spans the front and rear axles of the car, commonly known as the beam. It is the base of the car and is generally composed of two longitudinal beams and several cross beams. It is supported on the wheels through the suspension device, the front axle, and the 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 the assemblies maintain a relatively correct position and withstand various loads inside and outside the car. Therefore, the frame device is an important vehicle component. Among the existing frame devices, especially for the frames of engineering vehicles such as forklifts and loaders, Figure 3 , including a rear beam frame 1-1, a front beam frame 1-2, a rear connecting frame 1-3, a rear connecting beam 1-4 and an intermediate connecting beam 1-5. The ends of the rear connecting frame 1-3, the ends of the rear connecting beam 1-4 and the ends of the intermediate connecting beam 1-5 are respectively connected to the inner side surfaces of the rear beam frame 1-1, the front beam frame 1-2 and the inner side surfaces of the rear connecting frame 1-3, thereby forming a welded frame structure. This structure has the disadvantages of complex structure, difficult processing, and large deformation of the frame after welding. The overall deformation of the frame after welding brings great trouble to the assembly of the whole vehicle. Before the whole machine is assembled, this structural vehicle model needs to invest a lot of manpower and material resources to calibrate each frame and detect the deformation amount, which affects the assembly efficiency of the whole vehicle.
