Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicle technology, specifically relating to a wheel-track composite walking device. Background Technology
[0002] The wheel-track dual-mode composite walking device is mainly designed to enable fast travel on paved roads and convenient passage on soft roads, depending on the road conditions.
[0003] Traditional amphibious vehicles with wheeled and tracked modes employ two different modules, switching between them according to different operating conditions. In this approach, the wheeled and tracked locomotives are completely independent, with the wheeled locomotive as the primary mode and a lifting mechanism switching to the tracked mode. When one locomotive mode is in use, the other is a redundant structure. Alternatively, a structural change method can be used to combine and switch between the two modes, requiring additional drive force conversion structures and mode deformation mechanisms, making the entire system relatively complex. Both of these methods use two sets of locomotives, switching between them in different ways. These two locomotives are relatively independent, resulting in poor integration, state redundancy, and low adjustability, failing to achieve an optimal solution for mode switching.

[0006] (II) Technical Solution
[0007] To solve the above-mentioned technical problems, this utility model provides a wheel-track composite walking device, including a tire, a drive rim, and a track; the drive rim includes an inner rim body and an outer rim body; the inner side of the track is provided with meshing teeth;
[0008] Both the inner and outer rims are equipped with retaining rings, which are bolted together to form a U-shaped groove for mounting a tire. The other side of the retaining ring on the outer rim is a track mounting part, and the outer surface of the track mounting part is provided with a groove that engages with the drive teeth of the belt track. The drive surface of the belt track is 4cm-10cm higher than the tire wheel surface.
[0009] Furthermore, when the vehicle travels on a hard paved road, the tires are in direct contact with the ground, while the tracked vehicle is not in contact with the ground, and the wheeled travel mode is the dominant mode.
[0010] Furthermore, when driving on soft surfaces, the tire surface sinks and the track begins to make contact with the ground.

The structure is simple and the cost is low. At the same time, it can be easily converted into ordinary wheeled driving mode, which has high regional adaptability. Attached Figure Description
[0017] Figure 1 This is a schematic diagram of the wheel-track composite walking device of this utility model;
[0018] Figure 2 This is a schematic diagram of the drive wheel rim;
[0019] Figure 3 This is a schematic diagram of a tracked system. Detailed Implementation
[0020] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0021] This embodiment is generally applied to vehicles with two or more axles, such as 4×4, 6×6, and 8×8. The single-sided walking device is a set, consisting of a tire, a drive rim 1, and a track 2. The tire is mounted on the rim to achieve wheel walking function, and the wheel is mounted on the outer side of the rim. The inner side of the rim is provided with a groove for mounting the drive teeth of the track. The track is installed between the drive teeth of the rim on the same side to achieve track walking function.
[0022] The drive rim of this utility model consists of an inner rim body 1-1, an outer rim body 1-2, and connecting bolts 1-3. The inner rim body and the outer rim body's retaining ring surfaces combine to form a U-shaped groove for mounting the tire. The other side of the retaining ring on the outer rim body is configured as a track drive surface, which engages with the drive teeth of the track to form a tracked drive mode. The inner rim body and the outer rim body are connected as a single unit using connecting bolts. The drive surface of the track is 4cm-10cm higher than the tire-wheel drive surface, ensuring that when the vehicle travels on hard paved roads, the tires are in direct contact with the ground, while the track does not. The wheeled travel mode is the dominant mode. When traveling on soft surfaces, the tire travel surface sinks, and the track begins to contact the ground, resulting in a significant increase in the ground contact area of the walking device, thus improving the ability to traverse soft surfaces.
[0023] This utility model relates to a tracked belt, which consists of a running surface 2-1 and meshing teeth 2-2. It can generally be either a rubber track or a metal track. Depending on the installation method, the overall structure can be either an integral structure or a discontinuous structure. The meshing teeth match the tooth profile of the wheel rim outer body to ensure the transmission of driving force. The meshing teeth also match the retaining rings on both sides of the wheel rim outer body to ensure the correct running trajectory of the track when turning.
[0024] Combination Figures 1-3 The present invention will be described in detail through specific embodiments. The wheel rim connects to the wheel power transmission mechanism, transmitting driving force, braking force, etc., providing power to the traveling device, supporting the tire, providing a sealing structure for the tire, and providing drive for the track. The wheel rim adopts a split structure, consisting of an inner rim body and an outer rim body, connected by bolts. The wheel rim has a flat-bottomed split structure. The tire is mounted on the inner rim body, and the outer rim body assists the inner rim body in providing a sealing structure for the tire. The tire-based driving mode is suitable for high-speed travel on hard surfaces. A track support drive mechanism is located on the other side of the outer rim body, supporting the track and providing driving force for its rotation. The track is mounted on the support drive mechanisms of the two outer rim bodies, forming a complete track ring. When traveling on soft surfaces, the wheel support surface sinks, and the track support surface contacts the ground, forming a wheel-track composite driving mode.
[0025] In this embodiment, both wheeled and tracked travel modes are installed on the wheel rim, allowing for switching between wheeled and tracked travel depending on the road surface. Furthermore, the track used for tracked travel is easily detachable, further enhancing the performance of the wheeled travel mechanism. The high tire ground pressure, combined with the reduced ground pressure from the track contact with the ground on soft surfaces, allows the tires to provide greater driving force to the travel device. The integrated tracked drive structure on the wheel rim simultaneously drives both the wheels and tracks to provide driving force to the travel device.
[0026] The advantages of this embodiment are that the wheeled and tracked locomotives are highly integrated, with no redundant components in its own structure or conversion mechanism, resulting in extremely high lightweight characteristics and reliability. The wheeled and tracked locomotive modes can automatically switch according to the softness of the road surface. The simple structure requires no preparation time, making it particularly suitable for battlefield environments such as amphibious assaults.
[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
