For example, the third mounting wall 232 and the second mounting wall 231 may be integrally formed, or the third mounting wall 232 and the second mounting wall 231 may be welded and connected. This application takes the third mounting wall 232 and the second mounting wall 231 as an example for explanation, so as to improve the connection reliability of the third mounting wall 232 and the second mounting wall 231, reduce the risk of cracking caused by stress concentration at the connection between the third mounting wall 232 and the second mounting wall 231, and thus improve the structural stability of the third connecting bracket 23. The third mounting wall 232 is fixedly connected to the generator, and the third mounting wall 232 is bent toward the bottom of the suspension system 100, which is convenient for the assembly of the generator, and is conducive to fixing the generator on the frame longitudinal beam 3 through the third mounting wall 232, and further improving the position stability of the generator.

[0070] Furthermore, the side edges of the second connecting bracket 21 and the side edges of the third connecting bracket 23 may have reinforcing flanges, which may be welded to the side edges of the second connecting bracket 21 and the side edges of the third connecting bracket 23 by sheet metal welding, which is beneficial to improving the structural stability of the second connecting bracket 21 and the third connecting bracket 23, reducing the risk of cracking of the second connecting bracket 21 and the third connecting bracket 23, and improving the connection reliability between the second connecting bracket 21 and the corresponding longitudinal beam 3, as well as the connection reliability between the third connecting bracket 23 and the generator, thereby further realizing the reliable assembly of the second suspension device 2.

[0071] The vehicle according to the embodiment of the utility model includes the suspension system 100 of the vehicle range extender 4 described above. By providing the first suspension device 1 and the plurality of second suspension devices 2, it is convenient to sequentially install the vehicle range extender 4 assembly from the back to the front, thereby improving the assembly efficiency of the vehicle range extender 4. In addition, the suspension system 100 of the present application adopts a three-point suspension arrangement, which is conducive to improving the stability of the arrangement of the vehicle range extender 4, so that the suspension system 100 has better NVH performance, thereby improving the quality of the vehicle.
