Description

Technical Field

[0001] This utility model relates to the field of vehicle safety technology, specifically to a truck wheel axle auxiliary device. Background Technology

[0002] Trucks are vehicles used to transport goods, including mini, light, medium and heavy trucks. Truck axles are the core components of the truck chassis used for steering or load-bearing. Axles affect the load capacity, fuel consumption and driving safety of trucks. When truck axles malfunction, they need to be repaired in time to ensure driving safety.

[0003] Currently, in road rescue operations involving truck axle failure, jamming, or bearing breakage, traditional large auxiliary wheels, while providing some assistance in towing, also have drawbacks such as slow towing speed, damage to the road surface caused by the steel wheels, and easy displacement when going around curves. They cannot fully guarantee the needs and safety of rescue operations. Therefore, we propose a truck axle auxiliary device to solve the problems mentioned above. Utility Model Content

[0026] 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.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a truck wheel axle auxiliary device, including an external connecting rod 1, an inner bearing tire fixing plate 2, a fixing screw 3, an inner connecting rod 4, a first threaded rod 5, a first nut 6, a second threaded rod 7, an expansion block 8, a second nut 9, an expansion bracket 10, and an elastic ring 11;

[0028] First, as attached Figure 1 and attached Figure 2 As shown, use a jack to lift the axle and remove the truck's tires and half-axles. If the axle tires and half-axles have detached due to a malfunction, they do not need to be removed. Insert the external connecting rod 1 into the axle sleeve. The front end of the external connecting rod 1 has an easily adjustable expansion mechanism. Tighten the first nut 6 to open the expansion mechanism, which is then firmly fastened to the inner wall of the differential. Tighten the inner bearing tire mounting plate 2, and then use a wrench to tighten the fixing screw 3 again to fix the tire onto the inner bearing tire mounting plate 2. Then, retract the jack to tow the truck.

[0029] As attached Figure 1 -Appendix Figure 5As shown, a first threaded rod 5 is fixed to the rear end of the inner connecting rod 4, and a first nut 6 is fixed to the rear end of the first threaded rod 5. When the expansion mechanism needs to be adjusted, the first nut 6 is rotated, and the first nut 6 drives the first threaded rod 5 to rotate. The first threaded rod 5 is threadedly connected to the outer connecting rod 1. The inner connecting rod 4 is fixed to the front end of the first threaded rod 5. The inner connecting rod 4 is slotted and connected to the outer connecting rod 1, so that the inner connecting rod 4 can move within the outer connecting rod 1. A second threaded rod 7 is fixed to the front end of the inner connecting rod 4. The inner connecting rod 4 drives the second threaded rod 7 to move. The second threaded rod 7 is threadedly connected to the outer connecting rod 1. An expansion block 8 is integrally provided at the front end of the second threaded rod 7. The second threaded rod 7 drives the expansion block 8 to move, adjusting the position of the expansion block 8.

[0030] The expansion mechanism includes an expansion block 8, a second nut 9, an expansion bracket 10, and an elastic ring 11. Since the front cross-sectional length of the expansion block 8 is greater than the rear cross-sectional length, the expansion bracket 10 is tightly fitted to the outside of the expansion block 8. When the expansion block 8 moves back and forth, it pushes the expansion bracket 10 to move. The expansion bracket 10 is symmetrically arranged on the left and right sides. The expansion bracket 10 is rotatably connected to the external connecting rod 1, so that the expansion bracket 10 rotates on the external connecting rod 1. The outer side of the expansion bracket 10 is connected to the elastic ring 11. When the expansion bracket 10 moves, the elastic ring 11 limits the expansion bracket 10. The front end of the expansion block 8 is fixed with the second nut 9, and the expansion block 8 can also be adjusted from the front.

[0031] As attached Figure 1 As shown, the inner bearing tire fixing plate 2 is threadedly connected to the rear end of the external connecting rod 1, and the inner bearing tire fixing plate 2 is connected to the tire. Multiple fixing screws 3 are threadedly connected to the inner bearing tire fixing plate 2, and the fixing screws 3 are threadedly connected to the tire hub, so that the inner bearing tire fixing plate 2 and the tire are fixed together. The fixing screws 3 are set at equal angles on the inner bearing tire fixing plate 2 to ensure stability.

[0032] This is the entire working process of the truck wheel axle auxiliary device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.
