[0053] Reference Figure 2 and Figure 3 In some embodiments, a first reinforcing rib 240 is disposed on both the side wall of the first bracket body 210 close to the supporting member 500 and the side wall away from the supporting member 500 .

[0054] Specifically, the first reinforcing rib 240 is integrally formed with the first bracket body 210 , and the provision of the first reinforcing rib 240 helps to increase the rigidity and strength of the first bracket body 210 , thereby improving the overall structural strength of the first bracket 200 , so as to withstand various dynamic loads and vibrations during vehicle driving.

[0055] Reference Figure 1 and Figure 2 In some embodiments, the first reinforcing rib 240 located on the side of the first bracket body 210 close to the supporting member 500 extends to the first connecting plate 220 .

[0056] In the present embodiment, the first reinforcing rib 240 located on the side of the first bracket body 210 close to the supporting member 500 is extended to the first connecting plate 220, which helps to enhance the connection strength between the first bracket body 210 and the first connecting plate 220, and helps to disperse the load from the cab, that is, it helps to make the first bracket 200 evenly stressed, thereby ensuring the usability and extending the service life of the front suspension bracket of the cab; in addition, it helps to simplify the manufacturing and installation process of the first bracket 200, reduce the number of components and processing steps, thereby helping to improve production efficiency and reduce manufacturing costs.

[0057] Reference Figure 1 and Figure 4 In some embodiments, the second bracket 300 includes an integrally formed second bracket body 310, a third connecting plate 320 and a fourth connecting plate 330, wherein the top of the second bracket body 310 is provided with a second mounting hole 312 for the rotating member 400 to pass through; the third connecting plate 320 is extended and arranged at one end of the second bracket body 310 away from the second mounting hole 312, and the third connecting plate 320 is connected to the top wall of the corresponding longitudinal beam 120; the fourth connecting plate 330 is arranged on a side of the third connecting plate 320 away from the second bracket body 310, and the fourth connecting plate 330 is abutted against the outer side wall of the corresponding longitudinal beam 120, and the third connecting plate 320 and the fourth connecting plate 330 are detachably connected to the longitudinal beam 120 through the second mounting member.

[0058] Among them, the third connecting plate 320 is horizontally connected to the bottom end of the second bracket body 310, the fourth connecting plate 330 is vertically connected to the side wall of the third connecting plate 320 away from the second bracket body 310, and the second mounting member includes a second mounting bolt, through which the second bracket 300 and the corresponding longitudinal beam 120 can be detachably connected.

[0059] In this embodiment, through the cooperation of the third connecting plate 320, the fourth connecting plate 330 and the second mounting part, a detachable connection between the first bracket 200 and the longitudinal beam 120 is achieved, so that when the front suspension bracket of the cab needs to be replaced due to long-term fatigue use, the first bracket 200 can be replaced in time, thereby ensuring the usability and safety of the front suspension bracket of the cab.

[0060] Reference Figures 1 to 4 In some embodiments, the rotating member 400 includes a sleeve 410, a torsion bar 420 is provided in the sleeve 410, one end of the sleeve 410 extends out of the first mounting hole 212, and the other end of the sleeve 410 extends out of the second mounting hole 312, and the front suspension bracket of the cab also includes an adjustment component 600 for adjusting the installation angle of the sleeve 410.

[0061] Among them, one end of the sleeve 410 extends out of the first mounting hole 212 and is rotatably connected to the first bracket body 210, and the other end of the sleeve 410 extends out of the second mounting hole 312 and is rotatably connected to the second bracket body 310. The supporting member 500 includes two supporting seats, one of which is fixedly connected to one end of the sleeve 410, and the other is fixedly connected to the other end of the sleeve 410, and the two supporting seats are located between the first bracket body 210 and the second bracket body 310.

[0062] Specifically, one end of the torsion bar 420 located in the sleeve 410 is threadedly connected to the sleeve 410. When the torsion bar 420 is inserted into the sleeve 410, the torsion bar 420 can be threadedly tightened with the sleeve 410 by rotating it. The torsion bar 420 can enhance the torsional rigidity of the sleeve 410 and improve the resistance of the cab front suspension bracket to torsional load. During the use of the cab front suspension bracket, in order to further enhance the structural stability and improve the uniformity of load distribution, an adjustment component 600 is required to adjust the installation angle of the sleeve 410.

[0063] Reference Figure 1 and Figure 5 In some embodiments, the adjustment assembly 600 includes an adjustment arm 610 and an adjustment member 620, wherein the adjustment arm 610 is connected to one end of the sleeve 410 close to the first bracket body 210 or the second bracket body 310; the adjustment member 620 is arranged on the side wall of the first bracket body 210 or the second bracket body 310, and the adjustment member 620 is used to drive the adjustment arm 610 to rotate.

[0064] Among them, the adjustment arm 610 is connected to one end of the torsion bar 420 close to the first bracket body 210 or the second bracket body 310, and correspondingly, the adjustment member 620 is arranged on the side wall of the first bracket body 210 or the second bracket body 310. In this embodiment, the adjustment arm 610 is arranged on the side wall of the second bracket body 310 as an example.

[0065] Specifically, by cooperating with the adjusting arm 610 and the adjusting member 620, it is convenient to adjust the rotation angle of the torsion bar 420, thereby realizing the adjustment of the installation angle of the bushing 410. For example, when the driving arm is displaced in the counterclockwise direction, the connection tightness between the torsion bar 420 and the bushing 410 is reduced, and the adjusting member 620 is used to drive the adjusting arm 610 to rotate clockwise to increase the connection tightness between the torsion bar 420 and the bushing 410. At this time, the angle of the bushing 410 relative to the overall frame 100 changes, that is, the installation angle changes.

[0066] In this embodiment, the installation angle of the sleeve 410 is adjusted by the cooperation of the adjustment member 620 and the adjustment arm 610, so as to provide additional support when the sleeve 410 is subjected to torsional force, thereby reducing the deformation and displacement of the sleeve 410; in addition, the adjustment arm provides an additional fulcrum, so that the torsion bar 420 is more evenly stressed, avoiding the problem of excessive local stress caused by excessive concentrated load, thereby helping to improve the reliability and durability of the system.

[0067] Reference Figure 1 , Figure 5 and Figure 6 In some embodiments, the second bracket 300 also includes an adjustment arm mounting portion 340 and an adjustment member mounting portion 350, wherein the adjustment arm mounting portion 340 is arranged on the side wall of the second bracket body 310 away from the supporting member 500, and the adjustment arm mounting portion 340 is used to connect the adjustment arm 610; the adjustment member mounting portion 350 is arranged on the side wall of the second bracket body 310 away from the supporting member 500, and the adjustment member mounting portion 350 is used to connect the adjustment member 620.

[0068] Among them, according to the above content, it can be known that the adjustment of the installation angle of the sleeve 410 is achieved through the cooperation of the adjustment arm 610 and the adjustment member 620. Therefore, accordingly, an adjustment arm mounting portion 340 is set on the second bracket body 310 for connecting the adjustment arm 610, and an adjustment member mounting portion 350 is set on the second bracket body 310 for connecting the adjustment member 620.

[0069] Specifically, the adjusting member 620 includes an adjusting bolt, one end of which passes through the adjusting mounting portion and is threadedly connected to the adjusting mounting portion, and the other end of the adjusting bolt abuts against the adjusting arm 610, and the end of the adjusting arm 610 away from the adjusting bolt is threadedly connected to an end of the torsion bar 420 extending out of the second bracket body 310.

[0070] In this embodiment, by reserving an adjustment arm mounting portion 340 and an adjustment member mounting portion 350 on the second bracket body 310, it is convenient for the subsequent quick installation of the adjustment arm 610 and the adjustment bolt; and because the adjustment arm mounting portion 340 and the adjustment member mounting portion 350 are both integrally formed with the second bracket body 310, it helps to ensure the strength and stability of the overall structure of the second bracket 300.

[0071] Reference Figure 5 In some embodiments, a second reinforcing rib 360 is provided on a side wall of the second bracket body 310 located on one side of the adjusting arm mounting portion 340 , and the second reinforcing rib 360 extends to the adjusting arm mounting portion 340 and the adjusting member mounting portion 350 .

[0072] Specifically, the second reinforcing rib 360 is integrally formed with the second bracket body 310 , and the second reinforcing rib 360 helps to increase the rigidity and strength of the second bracket body 310 , thereby improving the overall structural strength of the second bracket 300 , so as to withstand various dynamic loads and vibrations during vehicle driving.

[0073] Reference Figure 4 In some embodiments, a third reinforcing rib 370 is provided on the side wall of the second bracket body 310 located on one side of the third connecting plate 320 , and the third reinforcing rib 370 extends to the upper surface of the third connecting plate 320 .

[0074] Specifically, the third reinforcing rib 370 is extended to the upper surface of the third connecting plate 320, which helps to enhance the connection strength between the second bracket body 310 and the third connecting plate 320, and helps to disperse the load from the cab, that is, it helps to evenly load the second bracket 300, thereby ensuring the usability and extending the service life of the front suspension bracket of the cab; in addition, it helps to simplify the manufacturing and installation process of the second bracket 300, reduce the number of components and processing steps, thereby helping to improve production efficiency and reduce manufacturing costs.

[0075] The present application provides stable support for the cab through the cooperation of the frame 100, the first bracket 200, the second bracket 300, the rotating member 400 and the supporting member 500. At the same time, the structure is simple, so that the front suspension bracket of the cab is lighter than the front suspension bracket of the cab in traditional technology, which is beneficial to saving manufacturing materials and energy saving and environmental protection.
