Abstract
The utility model relates to an axle body of a trailer axle, which comprises an axle tube and an axle head sleeved at the two ends of the axle tube, wherein a circular tube is arranged at the part where the axle head is sleeved at the two ends of the axle tube, and a square tube is arranged at the middle part of the axle tube. The axle body is characterized in that the wall thickness of the circular tube is more than that of the square tube, and the tube wall is gradually thickened at the transition part from the square tube to the circular tube. Due to the adoption of the structure of the thickened tube wall, the bending-resistant section modulus of the transition part between the circular tube and the square tube of the axle tube is enhanced, the stress born at the transition part is reduced, and the safety performance of the axle body is enhanced.
Description
Technical field:
The utility model relates to the axis structure of Trailer car shaft.
Background technology
The axis body that a kind of Trailer car shaft is arranged is made of central siphon and the spindle nose that is socketed in the central siphon two ends, and the position of central siphon two ends and spindle nose socket is pipe, and the middle part of central siphon is a rectangular tube.The axis body of this structure, the position of the pipe of its central siphon and rectangular tube transition is easy to generate strength weak, has unsafe hidden danger.
Summary of the invention
The purpose of this utility model is that the axis body at above-mentioned this axletree improves, and makes the axis body of this axletree more safe and reliable.
For this reason, the axis body of Trailer car shaft described in the utility model, comprise central siphon and the spindle nose that is socketed in the central siphon two ends, the position of central siphon two ends and spindle nose socket is a pipe, the middle part of central siphon is a rectangular tube, and especially, the wall thickness of described pipe is greater than the wall thickness of described rectangular tube, and the intermediate location from described rectangular tube to described pipe, the tube wall progressive additive.The constructional feature that described this tube wall thickens has improved the pipe of central siphon and the module of anti-bending section of rectangular tube intermediate location, has reduced the suffered stress of this intermediate location, has improved the safety performance of axis body.
Description of drawings
Fig. 1 is the structural representation of axis body;
Fig. 2 is the A-A section-drawing of the central siphon among Fig. 1;
Fig. 3 is the B-B section-drawing of the central siphon among Fig. 1.
The specific embodiment
The axis body of Trailer car shaft comprises central siphon 1 and the spindle nose 2 that is socketed in the central siphon two ends as shown in Figure 1.Referring to Fig. 2, the position of the two ends of central siphon 1 and spindle nose socket is a pipe simultaneously.Referring to Fig. 3, the middle part of central siphon 1 is a rectangular tube simultaneously.Characteristics of the present utility model are the wall thickness of the wall thickness of pipe greater than rectangular tube, and the intermediate location from the rectangular tube to the pipe, the tube wall progressive additive.
Axis body shown in Figure 1 can adopt following technology manufacturing to form: make central siphon with one section bigger round seamless steel pipe of diameter, footpath thermotropism hammering is carried out at the two ends of steel pipe, dwindle the diameter at steel pipe two ends, and make the thickness of steel pipe of forge hot place increase by 1.5～4mm than former thickness of steel pipe, one section position cold extruding squarely that diameter is bigger in the middle of the steel pipe, so far finish the making of central siphon then.Then process the pipe endoporus at central siphon two ends, spindle nose is pressed into the pipe location by interference fit, at last that central siphon and spindle nose is integrally welded, make axis body shown in Figure 1.
Claims (1)
1. the axis body of a Trailer car shaft, comprise central siphon and the spindle nose that is socketed in the central siphon two ends, the position of central siphon two ends and spindle nose socket is a pipe, the middle part of central siphon is a rectangular tube, it is characterized in that: the wall thickness of described pipe is greater than the wall thickness of described rectangular tube, and the intermediate location from described rectangular tube to described pipe, the tube wall progressive additive.
