Its speed ratio design covers a wide range, including direct gear (1:1), over speed gear (0.75:1 или 0.8:1), medium speed ratio (например. 4.11:1, 5.44:1) and low-speed gear (7.42:1, 9.84:1), which can meet the power demand under different working conditions.
– Применимые модели: mainly equipped with FAW Jiefang J6, J7 and other heavy truck models.
2. Other common models
– ZF 16-speed transmission (cooperative model): adopts double intermediate shaft design, supports 16 gears operation, suitable for long-distance transportation and other high-load scenarios, and needs to be equipped with special tools (НАПРИМЕР., high and low gear fork shaft fixing tool, main and secondary axle mounting jigs) to carry out maintenance.
Преимущества
–Reliable structure: mainly manual transmission (МТ), simple structure, low maintenance cost, high transmission efficiency (до 98% or more), suitable for heavy-duty transportation.
– Strong load-carrying capacity: low-speed gear design (например. 9.84:1) provides strong torque output and adapts to complex road conditions.
– High economy: manual gearbox fuel consumption performance is better than automatic gearbox, and the long-term use cost is lower.
Key maintenance spare parts
– Gear sets: including main and secondary shaft gears, synchronizer gears, need to match the original specifications to ensure the meshing accuracy.
– Несущий: such as NU309NRB, RNU308E and other models, need to be checked regularly for wear.
