[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 2-4The present invention provides a robust rear suspension assembly, the assembly structure of which includes a mounting bracket 11 and a limiting bracket 12; the limiting bracket 12 is fixedly connected to both ends of the bottom of the mounting bracket 11.

[0027] The fixing structure includes a fixing block 21, a connecting plate 22, a hydraulic clamping plate 23, and a shock absorber 24; the fixing structure also includes a wire 25 and a mounting plate 26.

[0028] The wire 25 is fixedly connected to one end of the connecting plate 22, and the mounting plate 26 is fixedly connected to the bottom end of the limiting bracket 12;

[0029] The fixing block 21 is fixedly connected to both ends of the mounting bracket 11, the connecting plate 22 is rotatably connected to one end of the fixing block 21, the hydraulic clamp 23 is rotatably connected to one end of the connecting plate 22, and the shock absorber 24 is slidably connected to one end of the hydraulic clamp 23.

[0030] The fixing block 21 and the mounting bracket 11 are connected by bolts, and the overall structure of the mounting bracket 11 is adjusted to be a welded component.

[0031] With the auxiliary cooperation between the fixing block 21 and the connecting plate 22, the center distance of the hydraulic clamp 23 can be effectively guaranteed to remain within the correct range.

[0032] Working principle: When the staff installs the rear suspension assembly;

[0033] First, by raising the crossbeam behind the mounting bracket 11 as a whole, space can be provided for the installation of a high-horsepower engine, and at the same time, the connecting plate 22 and the hydraulic clamp 23 provide a rotatable connection.

[0034] Furthermore, a shock absorber 24 is installed at the bottom of the hydraulic clamp 23, which can effectively ensure that the center distance of the hydraulic clamp 23 does not deviate.

[0035] This step reduces the overall weight of the rear suspension product, while fully addressing the space constraints faced by OEMs in assembling high-horsepower engines, and solving the problem of shock absorbers detaching at both ends in the past.

[0036] Please see Figure 1-3 As shown, this embodiment, based on the above embodiment, also includes a buffer structure;

[0037] The buffer structure includes a buffer 31 and an airbag 32;

[0038] The buffer 31 is fixedly connected to both ends of the mounting bracket 11, and the airbag 32 is fixedly connected to one end of the buffer 31.

[0039] The buffer structure also includes a connecting rod 33 and a movable rod 34;

[0040] The connecting rod 33 is fixedly connected to one end of the airbag 32, and the movable rod 34 is rotatably connected to one end of the connecting rod 33.

[0041] Among them, airbag 32 is shifted upwards as a whole.

[0042] Working principle: After the staff installs the rear suspension assembly;

[0043] First, when the mounting bracket 11 is affected by external forces, the buffer 31 can drive the airbag 32 to work, and the airbag 32 can drive the connecting rod 33 to rotate.

[0044] Next, a movable rod 34 is connected to one end of the connecting rod 33, which can buffer and disperse the force.

[0045] This step fully utilizes the shock absorption effect of the airbag 32, significantly improving the shock absorption effect and thus increasing the overall buffering capacity of the device.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
