As shown in fig. 1, a suspension device 1 provided in the embodiment of the present application may include a beam frame 11, the beam frame 11 may be connected to a vehicle body, the beam frame 11 may serve as an installation carrier, and the beam frame 11 may serve to improve the overall strength of the vehicle body.
As shown in fig. 1, in an embodiment, the suspension device 1 may further include a leaf spring support 12, a first leaf spring 13, and a second leaf spring 14, the leaf spring support 12 being connected to the beam 11, the first leaf spring 13 being connected to the leaf spring support 12, and the second leaf spring 14 being connected to the leaf spring support 12. Thus, the leaf spring support 12 can provide a mounting carrier for the first leaf spring 13 and the second leaf spring 14, facilitating the mounting and replacement of the first leaf spring 13 and the second leaf spring 14.
As shown in fig. 1, in one embodiment, both ends of the first leaf spring 13 are rotatably connected to the leaf spring support 12, and both ends of the second leaf spring 14 are rotatably connected to the leaf spring support 12. Thus, when the first leaf spring 13 receives vibration transmitted from the first axle 3, the first leaf spring 13 can be elastically deformed and can rotate with respect to the leaf spring bracket 12 to alleviate the vibration received by the beam 11 and the vehicle body. Similarly, when the second leaf spring 14 is subjected to vibration transmitted from the second axle 4, the second leaf spring 14 can be elastically deformed and can rotate relative to the leaf spring bracket 12 to alleviate the vibration to which the beam frame 11 and the vehicle body are subjected.
As shown in fig. 1, in an embodiment, the suspension device 1 may further include a connecting rod 15, and the connecting rod 15 is connected to the first leaf spring 13 and the second leaf spring 14.
