Crawler type travel assembly working principle
1. Driving principle: Power is also provided by the engine and transmitted to the drive sprocket through transmission devices such as gearbox and drive sprocket. The drive sprocket meshes with the chain links on the track, and when the drive sprocket rotates, it drives the track to move.
2. Walking principle: The track has a large contact area with the ground, and through the continuous rotation of the track, the vehicle moves on the ground. The movement of the track is similar to a circular chain, which continuously rolls on the ground under the drive of the sprocket, thereby pushing the vehicle forward or backward. Due to the high friction between the track and the ground, the track type walking assembly has good passability on complex terrains such as soft and muddy terrain.
3. Steering principle: The steering of tracked vehicles is usually achieved by changing the speed of the tracks on both sides. For example, when turning left, the left track slows down or stops, and the right track continues to move forward, causing the vehicle to turn left. Some tracked vehicles are also equipped with specialized steering mechanisms, such as steering clutches or hydraulic steering devices, to control steering more accurately.
4. Braking principle: The braking method is similar to that of wheeled vehicles, which restricts the movement of the driving sprocket or track through the braking device to stop the vehicle. Common braking devices include brakes, brake bands, etc., which achieve braking through friction with the drive sprocket or track.
