[0026] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the protection content of the present invention.

[0027] like Figure 1-Figure 5 As shown, a U-shaped gearbox auxiliary support device includes a support mechanism 1, a shock absorbing mechanism 2 and a connecting bracket;

[0028] The support mechanism 1 includes a support plate 5, on which a bolt 7 is mounted. The upper end of the bolt 7 is connected and fastened to the gearbox, thereby supporting the gearbox.

[0029] There are two shock absorbing mechanisms 2, and the two shock absorbing mechanisms 2 are symmetrically installed at both ends of the supporting mechanism 1;

[0030] The connecting bracket includes a left connecting bracket 3 and a right connecting bracket 4, one end of the left and right connecting brackets is connected to the shock absorbing mechanism 2, and the other end is installed on the frame;

[0031] The support mechanism 1, the shock absorbing mechanism 2 and the connecting bracket are connected to form a U-shaped structure.

[0032] In some embodiments, as Figure 2 、 Figure 3As shown, the lower end of the bolt 7 passes through the support hanger plate 5 and is connected to the pressing pad 8. An adjustment washer 9 is installed between the pressing pad 8 and the support hanger plate 5. The two ends of the bolt 7 are tightened with nuts respectively; the number of adjustment washers 9 is adjustable to adjust for cumulative errors during the assembly process, thereby avoiding brute force tightening during assembly, which may cause excessive stress on the bolt 7 and the support hanger plate 5.

[0033] In some embodiments, as Figure 3 As shown, the adjusting gasket 9 is provided with an L-shaped hole for easy installation on the bolt 7 . In actual use, the number of adjusting gaskets 9 installed on the bolt 7 can be adjusted as needed.

[0034] In some embodiments, as Figure 2 、 Figure 3 As shown, a reinforcing plate 6 is installed at the connection between the support hanger plate 5 and the bolt 7. The bolt 7 passes through the reinforcing plate 6, and the reinforcing plate 6 is laid flat on the support hanger plate 5. Since the connection between the bolt 7 is subjected to greater force, the reinforcing plate 6 plays a role in structural reinforcement.

[0035] In some embodiments, as Figure 1-Figure 3 As shown, the supporting hanging plate 5 is U-shaped, has a simple structure, and meets the requirements of lightweight design.

[0036] In some embodiments, as Figure 4 、 Figure 5 As shown, the shock absorbing mechanism 2 includes a hexagonal screw bolt with a hole 18 for connecting the supporting hanger plate 5 and the connecting bracket, and an upper shock absorbing pad 14 and a lower shock absorbing pad 16 are installed on the hexagonal screw bolt with a hole 18. The lower shock absorbing pad 16 is located between the bottom of the hexagonal screw bolt with a hole 18 and the connecting bracket, and is used to reduce the extrusion deformation force when the gearbox rises. The upper shock absorbing pad 14 is located between the connecting bracket and the supporting hanger plate 5, and is used to reduce the extrusion deformation force when the gearbox descends.

[0037] In some embodiments, as Figure 4 、 Figure 5 As shown, a cotter pin 10 and a hexagonal slotted nut 11 are installed on the top of the hexagonal head screw with hole bolt 18 for fastening to the supporting hanging plate 5.

[0038] In some embodiments, as Figure 4 、 Figure 5 As shown, the hexagonal screw bolt 18 is fitted with a sleeve 15 , which is located at the center of the upper shock-absorbing pad 14 and the lower shock-absorbing pad 16 , making it convenient for the upper shock-absorbing pad 14 and the lower shock-absorbing pad 16 to move up and down along the hexagonal screw bolt 18 .

[0039] In some embodiments, as Figure 4 、 Figure 5As shown, a plurality of washers are installed on the hexagonal screw bolt with a hole 18, including a small washer 12 installed above the support hanger 5, a large washer 13 installed between the support hanger 5 and the upper shock-absorbing pad 14, and a lower washer 17 installed between the bottom of the hexagonal screw bolt with a hole 18 and the lower shock-absorbing pad 16. The diameter of the center hole of the large washer 13 and the lower washer 17 is smaller than the diameter of the sleeve 15. The sleeve 15 can be pressed by the large washers 13 and the lower washer 17 at both ends. After the hexagonal screw bolt with a hole 18, the support hanger 5, and the small washer 12 are tightened by the hexagonal slotted nut 11, they can be fixed as a whole, and the whole will move synchronously during movement.

[0040] During installation (taking the left connecting bracket 3 as an example), if Figure 5 As shown, first install the lower washer 17 on the hexagonal screw bolt 18, then put the sleeve 15 on the hexagonal screw bolt 18 and position it above the lower washer 17, and then assemble the lower shock-absorbing pad 16, left connecting bracket 3, upper shock-absorbing pad 14, large washer 13, supporting hanger 5, small washer 12, hexagonal slotted nut 11, and cotter pin 10 on the hexagonal screw bolt 18 in sequence, and then assemble them into an integral part.

[0041] When the gearbox descends, the above components descend synchronously. The left connecting bracket 3 is fixed to the vehicle frame and does not move. The upper shock-absorbing pad 14 is squeezed and deformed, thereby providing a shock-absorbing effect. When the gearbox ascends, the above components ascend synchronously. The lower shock-absorbing pad 16 is squeezed and deformed, thereby providing a shock-absorbing effect. The right connecting bracket 4 and the left connecting bracket 3 are similar.

[0042] The U-shaped gearbox auxiliary support device of the utility model has an overall U-shaped structure, is simple in structure and light in weight, thereby reducing the weight of the entire vehicle, and the strength performance meets the use requirements.

[0043] Furthermore, those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, combinations of features from different embodiments are also intended to fall within the scope of protection of the present invention and form different embodiments. For example, in the above embodiments, those skilled in the art will be able to use them in combination based on the known technical solutions and the technical problems to be solved by this application.
