Application Models Of Sinotruk Howo A7 Gearbox Parts

The Sinotruk Howo A7 series features tailored gearbox configurations to meet diverse operational demands across its models.

For tractor applications, the 4X2 tractor primarily uses the HW19710 10-speed manual gearbox with a 3.93–4.8 rear axle ratio optimized for highway efficiency.
while the 6X4 tractor upgrades to the HW20716 16-speed transmission (handling up to 2000 N·m torque) for 420 HP engines, with optional 16-speed SmartShift AMT enhancing driver comfort in international markets.
The 8X4 tractor adopts heavier-duty HW25712 12-speed gearboxes paired with 4.42–5.73 axle ratios for off-road traction.
Dump trucks prioritize low-speed torque: both 6X4 and 8X4 models employ HW19710 or HW25712 transmissions with 5.73 axle ratios, featuring reinforced synchronizer rings and oil pumps to withstand construction site conditions.
The 6X4 cargo truck balances efficiency with the HW19710 gearbox and 4.42 ratio, using lightweight fork pendulum blocks for smooth shifting.

All models share a φ430mm diaphragm spring clutch with hydraulic-air control for consistent power transfer. Key gearbox components reflect a balance of commonality and specialization across Howo A7 variants. Universal parts like the range gear hub and oil seal rings reduce maintenance costs, while application-specific parts enhance durability. Heavy-duty input/output shafts and reinforced housings equip 8X4 models for extreme loads, while planetary gearset assemblies in 6X4 tractors enable auxiliary reduction.
Dump trucks benefit from differential lock mechanisms for uneven terrain, while tractors emphasize PTO compatibility for auxiliary power needs. The synchronizer rings’ spiral groove design ensures smooth engagement by matching gear speeds, critical for frequent shifting in both on-road and off-road scenarios. This modular approach ensures each model achieves optimal performance while maintaining parts interchangeability where possible.
