[0033] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] like Figures 1 to 4 As shown, this embodiment proposes a semi-trailer width-adjustable suspension mechanism, including two suspension bodies 1, and also includes: a frame 2, a slider 3, a transmission mechanism and a drive mechanism. Two sliders 3 are provided, and both sliders 3 are slidably set in the frame 2. The two suspension bodies 1 are respectively set on the two sliders 3. Through the cooperation between the frame 2, the slider 3, the transmission mechanism and the drive mechanism, it is convenient to adjust the distance between the two suspensions, and then adjust the width of the suspension according to different specifications of the frame, and the applicability is high.

[0035] Among them, the transmission mechanism is arranged on the frame 2, and is used to drive the two sliders 3 to move relative to each other. The transmission mechanism includes: a first toothed belt 4, a first gear 5, a slide 6 and a linkage assembly. The two sliders 3 are fixedly connected with the first toothed belt 4, and there are two first gears 5. The two first gears 5 are rotatably connected to the frame 2. The two first gears 5 are respectively engaged with the two first toothed belts 4. The two first gears 5 are fixedly connected with the slide 6. The linkage assembly is arranged on the frame 2, and is used to drive the two slides 6 to swing. The linkage assembly includes: a linkage shaft 7 and a moving screw 8. There are two linkage shafts 7, and the two linkage shafts 7 are sliding. The movable structure is set in the frame 2, and the two linkage shafts 7 are respectively slidably set in the two slides 6. There are two moving screws 8, and the two moving screws 8 are rotatably connected to the frame 2. Screw holes are provided on the two linkage shafts 7, and the two moving screws 8 are respectively threadedly connected in the two screw holes. Specifically, the linkage shaft 7 is driven to move by the rotation of the moving screw 8. When the linkage shaft 7 moves, it moves in the slide 6, and then drives the slide 6 and the first gear 5 to rotate. When the first gear 5 rotates, it drives the first toothed belt 4 and the slider 3 to move, thereby driving the suspension body 1 to move, thereby adjusting the width of the suspension body 1.

[0036] Among them, the driving mechanism is arranged on the frame 2, which is used to drive the transmission mechanism to move. The driving mechanism includes: a gear rack 9, a second gear 10 and a power assembly. A slide rod 13 is fixedly connected to the frame 2, and a sliding hole is opened on the gear rack 9. The slide rod 13 is slidably set in the sliding hole. The gear rack 9 is slidably set on the frame 2. The two moving screws 8 are fixedly connected to the second gear 10. The gear rack 9 is engaged with the two second gears 10. The power assembly is arranged on the frame 2, which is used to drive the gear rack 9 to move. The power assembly includes: a power block 11 and a driving screw 12. The power block 11 is fixedly connected to the gear rack 9, and the driving screw 12 is rotatably connected to the frame 2. A screw hole is opened on the power block 11, and the driving screw 12 is threadedly connected to the screw hole. Specifically, the driving screw 12 is rotated by the operator. When the driving screw 12 rotates, it drives the power block 11 and the gear rack 9 to move, thereby driving the second gear 10 and the moving screw 8 to rotate.

[0037] In this embodiment, when the width of the suspension needs to be adjusted, the operator rotates the drive screw 12. When the drive screw 12 rotates, it drives the power block 11 and the gear rack 9 to move, thereby driving the second gear 10 and the moving screw 8 to rotate. The rotation of the moving screw 8 drives the linkage shaft 7 to move. When the linkage shaft 7 moves, it moves within the slide 6, and then drives the slide 6 and the first gear 5 to rotate. When the first gear 5 rotates, it drives the first toothed belt 4 and the slider 3 to move, thereby driving the suspension body 1 to move, thereby adjusting the width of the suspension body 1.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
