Embodiment 1

[0022] Such as figure 2 The axle body of the high-rigidity semi-trailer shown, the axle body includes the leaf spring seat assembly plane 1, the vertical surface 2 adjacent to the leaf spring seat assembly plane 1 and the lower plane 3 opposite to the leaf spring seat assembly plane 1, and the vertical plane The lower half of 2 and the lower plane 3 form a U-shaped structure. The U-shaped structure includes a first bottom arc 4 and a connecting arc 5 , the first bottom arc 4 is connected to the vertical surface 2 through the connecting arc 5 . The center of the first bottom arc 4 depends on the configuration of the rolls of the cold extrusion plant. The first bottom arc 4 and the vertical surface 2 are connected and transitioned through the connecting arc 5 , and are formed freely during the gradual change process of the workpiece.

[0023] figure 1 and figure 2 The wall thickness in both is 12mm, figure 1 The flexural section modulus is 256347.47, figure 2 The flexur...

Embodiment 2

[0025] Such as image 3 In the shown high-rigidity semi-trailer axle body, the lower half of the vertical plane 2 and the lower plane form a U-shaped structure. The unusual U-shaped structure includes a second bottom arc 6 and a connecting tangent 7 , and the second bottom arc 6 is connected to the vertical surface 2 through the connecting tangent 7 . The connecting tangent line 7 is trumpet-shaped.

[0026] Such as figure 1 and image 3 The wall thickness is 12mm, figure 1 The flexural section modulus is 256347.47, image 3 The flexural section modulus is 291810.25, an increase of 13.83%.

Abstract

The invention relates to a high-rigidity semitrailer axle body and belongs to the field of automobile axles. The high-rigidity semitrailer axle body comprises a plate spring seat assembling plane, a perpendicular plane and a lower plane, wherein the perpendicular plane is adjacent to the plate spring seat assembling plane and the lower plane is opposite to the plate spring seat assembling plane. The high-rigidity semitrailer axle body is characterized in that a specially-shaped structure is formed by combining the perpendicular plane with the lower plane. Through changes of the shape of the cross section of the axle body, the section modulus in bending of the axle body is improved, and therefore the rigidity of the axle body is improved, but the height of a whole semitrailer will not be changed along with the changes of the shape. Existing parts can serve as most connection parts needed by assembling of a suspension system and an axle. The high-rigidity semitrailer axle body is easy to machine and produce.

Description

technical field [0001] The invention relates to a high-rigidity semi-trailer axle body, which belongs to the field of automobile axles. Background technique [0002] At present, the cross-sections of the semi-trailer axles produced by domestic and foreign semi-trailer axle manufacturers are all square or circular. Patent CN2374376Y "Integral Axle of Semi-trailer", Patent CN201925322U "A New Type of Axle", Patent CN201506215U "Integral Axle for Semi-trailer Transport Vehicle" and Patent CN201228039Y "Axle Body of Trailer Axle" The cross sections are all square. Use the methods described in the patent CN202015776U "Axle Pushing Device" and the patent CN2455399Y "A Semi-trailer Rear Axle Square Shaft Forming Machine". And some small-tonnage semi-trailer axles and agricultural trailer axles produced with 146 millimeters of diameter steel pipes and 127 millimeters of diameter steel pipes, such as the axle body cross-section of patent CN101547914A " semi-trailer axle and suspens...
