[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0016] Embodiment one:

[0017] According to Figs. 1-2 As shown in the figure, a friction welding variable-diameter traction crossbeam assembly includes a crossbeam main body 1, and the two ends of the crossbeam main body 1 are fixedly welded with front traction hook seats 2. The friction welding process is adopted here, and the strength is higher. Mounting holes 8 are formed in the front traction hook seats 2. Weight reduction grooves 7 are formed on one side of the mounting holes 8. The weight reduction grooves 7 are triangular. This design can realize lightweight design, and the triangular weight reduction grooves 7 are more stable, ensuring the strength of the structure. Fixed hole groups 4 are formed on the outer sides of two corners of the weight reduction grooves 7. First fixed holes 5 are formed on the opposite sides of the fixed hole groups 4. Second fixed holes 6 are formed on the outer side of the other corner of the weight reduction grooves 7.

[0018] The front traction hook seats 2 are symmetrically welded at the two ends of the crossbeam main body 1. This design can ensure the connection with the frame girder. This is prior art, and no more description is given.

[0019] The diameters of the two ends of the crossbeam main body 1 are greater than the diameter of the middle part of the crossbeam main body 1, and the two ends of the crossbeam main body 1 are transitioned to the middle part through tapered rods. On the one hand, this can realize the lightweight operation of the automobile, and on the other hand, the strength of the crossbeam main body 1 can not be reduced.
