[0008] The purpose of the present invention is to use bolts to directly connect the beams of each section for segmented frame structures that will bear torsion, bending, stretching, shearing, vibration or alternating stress due to different road conditions during actual use. Failure is prone to occur under complex stress conditions; provide a convenient and reliable connecting joint to connect the segmented frame into a whole, and the connecting joint can bear the load applied to the joint by the vehicle under various working conditions during operation Forces such as tension, bending, twisting and shearing increase the reliability of the connection

Embodiment 1
[0044] Such as Figure 7a , Figure 7b , Figure 8 As shown, the connecting joint includes connecting seats 6, 8 and connecting pieces 7, 9. The cross section of the main beam of the frame is in the shape of "I", and the structure of the connecting seats 6, 8 matches it, and the cross section is also in the shape of "I". One side of the first connecting seat 6 is welded with the main beam 4 of the front section, the other side is connected with one side of the second connecting seat 8, and the other side of the second connecting seat 8 is welded with the main beam 5 of the rear section;
[0045] Wherein, the first connection base 6 includes a first base 61, a second base 63 and a connection portion 62 connecting the two bases; the two ends of the first base 61 and the connection portion 62 extend upward respectively, forming a first The protruding portion 610 and the second protruding portion 612, that is, the protruding portion extends in a direction parallel to the connect...

[0052] Such as Figure 10a , Figure 10b , Figure 11a , Figure 11b , Figure 12 As shown, the connecting joint includes connecting seats 6, 8 and connecting pieces 7, 9. The cross section of the main beam of the frame is in the shape of "I", and the structure of the connecting seats 6, 8 matches it, and the cross section is also in the shape of "I". ” shape; one side of the first connecting seat 6 is welded with the main beam 4 of the front section, the other side is connected with one side of the second connecting seat 8, and the other side of the second connecting seat 8 is welded with the main beam 5 of the rear section; The slots 611, 631, 811, and 831 are all trapezoidal slots, arranged in the vertical direction, set parallel to the web of the main beam "I" section steel, and perpendicular to its length direction; the raised parts 71, 72, 91 of the connectors 7, 9 , 92 are trapezoidal structures matching the grooves 611, 631, 811, 831.
Embodiment 3
[0054] Such as Figure 13 As shown, the protrusions 71, 72, 91, 92 of the connectors 7, 9 are single-slope trapezoidal structures, that is, the force-bearing surfaces 710, 720, 910, 920 of the protrusions are inclined planes, and the inclined planes and the grooves 611 , 631, 811, 831 are matched with the matching faces.
[0055] The stress-bearing surface of the protrusion may also be an arc surface.

Abstract
The invention belongs to the field of mechanical connection, and relates to a combined connection joint for a vehicle frame beam, which is divided into a fixed part and a connecting part; The whole is inseparable; the connecting piece of the connecting part connects the two connecting seats to be connected and respectively fixed on the main beam of the vehicle frame into a whole. The combined connection joint mainly bears the bending stress generated during the bending of the frame during operation and the tensile stress generated during traction by the connecting piece; and the contact area is large, the fastening force after connection is large, and the connection rigidity is greatly improved. Improvement greatly improves the torsional performance of the frame when it is twisted; and it is easy to replace; it has high reliability and is especially suitable for container transport semi-trailers with multi-section main beam structures.
Description
technical field [0001] The invention belongs to the field of mechanical connection, and relates to a connection joint of a multi-section beam, in particular to a connection joint of a multi-section frame beam of a container semi-trailer. Background technique [0002] At present, the overall length of the inland container in the United States is 53 feet, and the semi-trailer transporting the 53-foot container is longer than the 53-foot container. After the semi-trailer is manufactured in China, it will be shipped to the United States by sea. There are two transportation options: one is to be transported by bulk carrier, and the other is to be transported by container ship. When transported by bulk carrier, it can be transported in the form of a whole vehicle, but it takes up a lot of space and the freight is high. In addition, there are few bulk carrier flights to meet delivery requirements. When transported by container ships, there are many flights and low freight rates, ...
