At the same time, it also helps to adapt to the complex stress conditions of pressure and tension of the expansion cylinder support ear 10.

[0048] Specifically, the top surface 81 of the auxiliary support seat 80 is fixed on the bottom surface of the front cross beam 20 , and the side surface 82 of the auxiliary support seat 80 is fixed on the longitudinal connecting plate 30 and the side surface 24 of the sunken curved portion 23 .

[0049] See also Figure 1 and Figure 4 Similarly, the auxiliary support bracket 80 is connected to the longitudinal connecting plate 30 by an inclined support 70 .

[0050] Furthermore, in order to improve the structural strength, the front cross beam 20, the suspension upper cross beam 50, the suspension lower cross beam 60, the auxiliary support bracket 80 and the oblique support 70 involved in this embodiment adopt a three-dimensional structure.
