A tracked chassis is a specialized piece of equipment distinct from a wheeled chassis, primarily used for operations in various complex terrains.It makes contact with the ground via tracks, providing a large contact area that offers strong traction and stability, making it suitable for muddy, steep slopes, gravel, snow, desert, mountainous, and other complex terrains.Compared to wheeled chassis, tracked designs offer superior off-road capability and load-bearing capacity, making them widely used in over 10 industries including security, disaster relief, industry, mining, agriculture, forestry, polar regions, and special environments.

Customizable dimensions, appearance, load capacity, and various development functions, enabling unmanned control, Beidou navigation, autonomous navigation, automatic obstacle avoidance, and automatic following. Customizable rubber tracks with various appearances, dimensions, embedded magnets, corrosion resistance, oil resistance, high temperature resistance, and anti-static properties can also be tailored to meet customer usage requirements and environmental conditions.

1. Soft or Low-Bearing-Capacity Ground:Such as swamps, muddy areas, sandy terrain, snowfields, farmland, and wetlands.

The wide contact area of tracks significantly reduces ground pressure, preventing the vehicle from sinking. For example, tracked snow vehicles distribute their weight over a large surface area to avoid getting stuck in deep snow.

2. Rugged, hard terrain: mountains, rock piles, ruins, gravel roads, ravines, etc.

Tracks have a continuous rolling surface and strong obstacle-crossing capabilities, enabling them to climb slopes of 30° or more and cross obstacles up to 0.5 meters high (depending on chassis size and power). 

3. Slippery or Low-Friction Surfaces: Ice, moss-covered ground, muddy roads after rain, oily surfaces, etc.

The treads on the track surface (such as cleats on steel tracks) provide enhanced traction and reduce slippage. For example, polar exploration vehicles use tracks equipped with ice claws to increase grip on icy surfaces.

4. Extreme High or Low-Temperature Environments:deserts, volcanic regions, polar areas, and permafrost zones.

High-Temperature Environments: Track materials (such as heat-resistant rubber or composite metals) can withstand extreme temperatures (e.g., surface temperatures in deserts can exceed 70°C).

Low-Temperature Environments: Cold-resistant rubber tracks or heating systems prevent material embrittlement (e.g., Arctic research robots can operate at temperatures as low as -50°C).

5. Areas with Dense Obstacles: Urban ruins, collapsed buildings, dense forests, and shrublands.

Tracked chassis have a low center of gravity and strong stability, allowing them to crush small obstacles (such as debris and branches) while reducing the risk of rollover. For example, rescue robots can navigate through rubble in post-earthquake disaster zones.

6. Environments Where Ground Damage Must Be Minimized: lawns, farmland, archaeological sites, and paved roads.

The low ground pressure of tracks minimizes damage to the surface (e.g., agricultural machinery tracks help protect soil structure). Some lightweight tracks (such as rubber tracks) can even travel short distances on asphalt without damaging the road surface.

7. Not Recommended Scenarios (Use with Caution)

Highways or Urban Roads: Tracks cause significant wear on hard surfaces and are speed-limited (typically off-road speed is below 20 km/h).

Confined spaces: Large turning radius (requires on-the-spot turning technology), less flexible than wheeled chassis.

Light Load and Short-Distance Transportation: Lower cost-effectiveness compared to wheeled systems; wheeled chassis are generally more suitable for such applications.

The tracked chassis consists of complex and precision-engineered parts that work together to achieve high mobility, stability, and load-bearing capacity.

1. Track: The part that comes into direct contact with the ground. Its wide surface area distributes the vehicle's weight, reducing ground pressure.

Key Parameters: Width (affects ground pressure), pitch (distance between adjacent track plates), number of teeth (engages with the driving wheel).

2. Driving Wheel / Sprocket: Drives the track through gear transmission and serves as the core component for power delivery.

3. Idler Wheel: Adjusts the direction of the track and maintains proper tension, helping control vehicle steering.

4. Road Wheels: Support the vehicle’s weight and distribute pressure, reducing track deformation.

5. Track Roller: Prevents sagging or lateral deviation of the track, ensuring smooth and stable operation.

6. Suspension System: Absorbs shocks, maintains track-to-ground contact, and improves ride stability and comfort.

7. Power System (Engine & Transmission): Provides driving force and transmits it to the driving wheel via the transmission system.

8. Steering Mechanism: Enables vehicle steering, typically by adjusting the speed or direction of each side of the track independently.
