DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will describe in detail the embodiments of the present application in conjunction with the drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0025] As Figure 1 and Figure 2As shown in the figure, the backlash elimination gear assembly for new energy logistics vehicles provided in this embodiment includes a rotating shaft 1. One end of the rotating shaft 1 is provided with a mounting seat 8. One end of the mounting seat 8 is fixedly installed with a mounting shaft 4. A first gear 2 and a second gear 3 are sleeved outside the mounting shaft 4. A disc spring 9 is detachably installed between the first gear 2 and the second gear 3. A retaining sleeve 5 is sleeved on the surface of the mounting shaft 4. A limiting structure is arranged between the retaining sleeve 5 and the second gear 3. Slots 11 are opened on both sides of the mounting shaft 4. Insert blocks 10 are arranged on both sides of the inner ring of the first gear 2. Sliders 25 are arranged on both sides of the inner ring of the retaining sleeve 5. The sliders 25 and the insert blocks 10 cooperate with the slots 11. The limiting structure includes a groove 12. The groove 12 is opened on one side of the second gear 3. The groove 12 is annular. A clamping tooth ring 13 is arranged inside the groove 12. A pressure sleeve 14 is movably installed at the lower end of the retaining sleeve 5. A clamping tooth ring 18 is arranged at the lower end of the pressure sleeve 14. The clamping tooth ring 18 is clamped with the clamping tooth ring 13;

[0026] In this embodiment, when the user moves the retaining sleeve 5 upward, the retaining sleeve 5 drives the pressure sleeve 14 to move upward. The pressure sleeve 14 drives the clamping tooth ring 18 to move upward, so that the clamping tooth ring 18 is disengaged from the clamping tooth ring 13, so that the second gear 3 can rotate, so that a deviation occurs between the first gear 2 and the second gear 3, which is convenient for the second gear 3 to eliminate the backlash for the first gear 2 and can adapt to gears in different scenarios. When the pressure sleeve 14 moves downward, the clamping tooth ring 18 is clamped with the clamping tooth ring 13, and the second gear 3 can be limited, which is convenient for limiting the second gear 3.

[0027] As Figure 2 and Figure 3 shown in the figure, in the backlash elimination gear assembly for new energy logistics vehicles provided in this embodiment, an installation groove is opened inside the lower end of the retaining sleeve 5. A moving ring 15 is movably installed inside the installation groove. Pressure rods 17 are uniformly installed at the lower end of the moving ring 15. The lower ends of the pressure rods 17 movably penetrate through the outside of the retaining sleeve 5 and are fixedly connected with the pressure sleeve 14. A compression spring 16 is sleeved on the surface of the pressure rods 17;

[0028] In this embodiment, when the retaining sleeve 5 moves downward, driving the pressure sleeve 14 to move downward, when the clamping tooth ring 18 at the lower end of the pressure sleeve 14 is clamped with the clamping tooth ring 13, the retaining sleeve 5 continues to move downward and inserts into the inside of the pressure sleeve 14. The pressure sleeve 14 drives the moving ring 15 to move upward through the pressure rods 17. The moving ring 15 drives the compression spring 16 to stretch. Under the action of the compression spring 16, the pressing of the pressure sleeve 14 is strengthened, and the clamping of the clamping tooth ring 18 with the clamping tooth ring 13 is strengthened.

[0029] As Figures 2 to 4As shown, for the backlash-eliminating gear assembly of the new energy logistics vehicle provided in this embodiment, a connection structure is provided between the pressing sleeve 14 and the mounting shaft 4. The connection structure includes an annular groove 19, which is opened at the upper end of the clamping sleeve 5. An annular rail 20 is movably installed inside the clamping sleeve 5. The upper end of the annular rail 20 is provided with an adjusting sleeve 6, and the adjusting sleeve 6 is threadedly connected to the mounting shaft 4. Clamping holes 24 are evenly opened at the lower end of the annular groove 19. Moving grooves are evenly opened inside the adjusting sleeve 6, and clamping rods 21 penetrate through the inside of the moving grooves. The lower end of the clamping rod 21 is clamped with the clamping hole 24. The upper end of the clamping rod 21 is located outside the adjusting sleeve 6 and is provided with an adjusting ring 7. A moving block 22 is sleeved on the surface of the clamping rod 21, and a return spring 23 connected to the moving block 22 is sleeved on the surface of the clamping rod 21;

[0030] In this embodiment, the user pushes the adjusting ring 7 upward, and the adjusting ring 7 drives the clamping rod 21 to move upward, so that the clamping rod 21 is pulled out from the inside of the clamping hole 24, so that the annular rail 20 can rotate inside the annular groove 19, and the adjusting sleeve 6 can rotate at the upper end of the clamping sleeve 5. The adjusting sleeve 6 moves on the surface of the mounting shaft 4 through threads, and the adjusting sleeve 6 can drive the clamping sleeve 5 to move up and down. When the clamping sleeve 5 moves downward to the maximum position, the clamping rod 21 moves to the position of the clamping hole 24, and the clamping rod 21 is inserted into the inside of the clamping hole 24 under the action of the return spring 23, so as to facilitate the synchronous limit of the clamping sleeve 5 and the adjusting sleeve 6 and prevent the adjusting sleeve 6 from rotating, affecting the clamping between the clamping tooth ring 13 and the clamping tooth circle 18.
