HOWO T7H Tractor Truck

The SINOTRUK T7H transmission is a heavy-duty gearbox designed for robust performance, featuring multiple gears for efficient power transmission and reliability in tough driving conditions.

1. High transmission efficiency: Made of high-strength materials and high-quality gears, it ensures stable performance over long periods, enhances power transmission efficiency, reduces power loss, and improves driving stability.
2. Strong load-carrying capacity: The main box adopts a dual intermediate shaft structure with floating ends of the main shaft and floating main shaft gears, ensuring uniform load distribution. With a maximum input torque of 2500Nm, it adapts to heavy-duty and high-intensity operation requirements.
3. Smooth shifting: The range gear auxiliary box assembly is upgraded to optimize shifting smoothness, reduce power loss, and make the transmission system operate more smoothly.
4. Convenient operation: The AMT version of the T7H transmission, developed by SINOTRUK in cooperation with WABCO, arranges functional buttons clearly and effectively, making it easy for drivers to operate. Compared with manual transmissions, it is more convenient and reliable.
5. Low maintenance cost: With a modular structure, the range gear auxiliary box assembly can be replaced individually, offering high maintenance convenience and reducing maintenance costs and time.
6. Good fuel economy: Some transmissions are equipped with a low-speed neutral coasting program. The AMT transmission can automatically shift up and down based on the driver's accelerator pedal depth and vehicle operation, capturing the optimal shifting timing in the engine's economic speed range to minimize fuel consumption.
7. Strong adaptability: Equipped with helical gear transmission mechanisms, it demonstrates strong adaptability under extreme working conditions. With multiple gear options, it meets driving needs in different working conditions.
