Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a high-speed tracked unmanned vehicle drive wheel fixing mechanism. Background Technology

[0002] The fixation of the drive wheels of an autonomous vehicle is crucial to ensuring stable operation. It not only affects the vehicle's driving safety but also its overall performance and reliability. Existing fixation structures generally require CNC machine tool processing, which is complex and incurs high costs in terms of materials, labor, and time.

[0003] To address the shortcomings of existing technologies, it is necessary to design a high-speed tracked unmanned vehicle drive wheel fixing mechanism. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-speed tracked unmanned vehicle drive wheel fixing mechanism.

[0005] A high-speed tracked unmanned vehicle drive wheel fixing mechanism is disclosed, which is bolted to the front fork arm of the unmanned vehicle. The front fork arm is mounted on the bearing seat of the drive wheel of the unmanned vehicle. The mechanism includes two side mounting plates, an upper mounting plate, and a lower mounting plate. Both the upper and lower mounting plates are U-shaped and have several assembly holes near the opening. Both side mounting plates have several protrusions corresponding to the assembly holes, and also have matching notches and several mounting holes. The two side mounting plates are fixed to the front fork arm assembly area by inserting the protrusions into the assembly holes on the upper and lower mounting plates respectively and spot welding. The side mounting plates are fixed to the front fork arm of the unmanned vehicle through the mounting holes, so that the matching notches are tangent to the bearing seat of the drive wheel of the unmanned vehicle.

[0006] Furthermore, the unmanned vehicle front fork includes two front fork mounting plates and a front wheel connecting sleeve; each of the two front fork mounting plates is divided into a mounting section and a connecting section. The mounting section is mounted on the bearing seat of the unmanned vehicle's drive wheel, and the connecting section is fixed to both ends of the front wheel connecting sleeve. The connecting section of the front fork mounting plate passes through the front fork assembly area until the front wheel connecting sleeve passes through the front fork assembly area, and the fitting notch is tangent to the bearing seat of the unmanned vehicle's drive wheel. The two side mounting plates are fixed to the mounting sections of the two front fork mounting plates respectively through mounting holes.

[0007] Furthermore, both side mounting plates are perpendicular to the upper and lower mounting plates, and the contact points between the upper and lower mounting plates and the side mounting plates extend to form placement surfaces for mounting the front fork arms of the unmanned vehicle.

[0008] Furthermore, the side mounting plate, upper mounting plate, and lower mounting plate are all made of carbon steel.

[0009] Furthermore, the front fork arm assembly area is a U-shaped region that is adapted to the front fork arm of the unmanned vehicle, and the shape of the adaptation notch is adapted to the bearing seat.

[0010] Beneficial effects: The two side mounting plates, the upper mounting plate and the lower mounting plate in this utility model are all cut by laser cutting and then welded together by plugging. The process is simple, and it is easy to fix and install with the front fork arm of the unmanned vehicle by bolts. The overall material and labor costs are also low, and the modular design makes it easy to replace. Attached Figure Description

[0017] 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.

[0018] Please refer to Figures 1-4This embodiment proposes a high-speed tracked unmanned vehicle drive wheel fixing mechanism, which is fixed to the unmanned vehicle's front fork arm by bolts. The unmanned vehicle's front fork arm is mounted on the bearing seat of the unmanned vehicle's drive wheel. It includes two side mounting plates 1, an upper mounting plate 2, and a lower mounting plate 3. The upper mounting plate 2 and the lower mounting plate 3 are both U-shaped, and have several assembly holes near the opening. Each side mounting plate 1 is provided with several protrusions corresponding to the assembly holes, and also has matching notches and several mounting holes. The shape of the matching notches is adapted to the bearing seat. The two side mounting plates 1 are respectively inserted into the upper mounting plate through the protrusions. The mounting holes on the upper and lower mounting plates 2 and 3 are spot-welded to form the front fork arm assembly area. This U-shaped area is adapted to the front fork arm of the autonomous vehicle. The side mounting plate 1 is fixed to the front fork arm via mounting holes, ensuring the fitting notch is tangent to the bearing seat of the autonomous vehicle's drive wheel. Both side mounting plates 1 are installed perpendicularly to the upper mounting plate 2 and lower mounting plate 3. The contact points between the upper and lower mounting plates 2 and 3 and the side mounting plates 1 extend to provide a placement surface for the front fork arm, facilitating placement and limiting its position, thus increasing the stability of the drive wheel. The side mounting plates 1, 2, and 3 are all made of carbon steel. They are cut using laser cutting and then welded together via insertion, a simple process. The bolted installation to the front fork arm is convenient, resulting in lower material and labor costs, and modular design for easy replacement.

[0019] The unmanned vehicle front fork arm includes two front fork arm mounting plates and a front wheel connecting sleeve. Each front fork arm mounting plate is divided into a mounting section and a connecting section. The mounting section is installed on the bearing seat of the unmanned vehicle's drive wheel, and the connecting section is fixed to both ends of the front wheel connecting sleeve. The connecting section of the front fork arm mounting plate passes through the front fork arm assembly area until the front wheel connecting sleeve passes through the front fork arm assembly area, and the fitting notch is tangent to the bearing seat of the unmanned vehicle's drive wheel. The two side mounting plates 1 are fixed to the mounting sections of the two front fork arm mounting plates respectively through mounting holes. By fixing to the front fork arm mounting plates, the stability of the unmanned vehicle's drive wheel is ensured, and replacement is convenient and widely applicable.
