[0024] Please see Figures 2 to 7 A drive shaft bearing housing connection structure includes: a seat plate 1, a bottom crossbeam 2, a connecting member 3, a support beam 4, and at least one stiffening plate 5. The seat plate 1 is provided with mounting holes 10 for mounting drive shaft bearing housings 6. In this embodiment, the mounting holes 10 are located at the bottom of the seat plate 1. The bottom crossbeam 2 is welded to one side of the seat plate 1. In this embodiment, the seat plate 1 is Y-shaped. The seat plate 1 has a notch 11 on its upper part, thereby forming a first boss 12 and a second boss 13 on the top of the seat plate 1.
