[0002] A crawler gearbox is a device used to control the speed and direction of a crawler vehicle. Its working principle mainly involves two key components: a gear set and a clutch. 1. Gear set: The gear set is composed of gears of different sizes and is used to achieve different transmission ratios. When the gear sets are paired in a certain way, the transmission speed and torque will be changed, thereby changing the vehicle's driving speed. By operating the handle or control device of the crawler gearbox, the combination of the gear sets can be adjusted to achieve driving at different speeds. 2. Clutch: The clutch is used to connect or disconnect the engine and the transmission to control the transmission of power. In the crawler gearbox, the function of the clutch is to adjust the movement state of the crawler. When the clutch is completely disengaged, the power of the engine is not transmitted to the crawler and the vehicle stops. When the clutch is fully connected, the power of the engine is transmitted to the transmission and the crawler through the clutch, and the vehicle starts to travel. The existing crawler-type meshing sleeve shift gearbox has a poor heat dissipation effect, and its heat dissipation speed is slow and the effect is poor, which makes it difficult to discharge the temperature of the gearbox, seriously affecting the service life of the gearbox.
