DuraMac ZQC2000L Wheeled Vehicle Transfer Case
The ZQC2000L is a heavy-duty transfer case for wheeled vehicles, built to excel in demanding operations. It delivers a maximum input torque of 25000Nm and a maximum input speed of 2800rpm, with an input-output center distance of 396mm, ensuring reliable power transmission.
This unit offers flexible speed ratios: 0.89 or 1 for on-road high gear and 1.536 for off-road low gear, selectable via 3-pneumatic or 3-mechanical shifting. It features front axle output with an indication switch and an inter-axle differential with selectable torque ratios (1:1, 1:2.214, 1:2.696, or 1:3), optimizing traction and stability across diverse terrains.
With an operating air pressure of 6.5–10 bar, a lubricant oil capacity of 8.4L, and a total weight of 375kg, it balances durability and efficiency. Optional units include an N200 PTO or ZF8605 oil pump connection device, and input flanges are available in DIN180 and T180 (ISO8667) specifications.
Advantages of ZQC2000L Wheeled Vehicle Transfer Case
High Loading Capacity: The ZQC2000L transfer case delivers a maximum input torque of 25000Nm and a maximum input speed of 2800rpm, with an input-output center distance of 396mm. This robust design ensures stable and reliable power transmission, making it ideal for heavy-duty wheeled vehicles operating under extreme loads.
Built-in Lubrication Pump: It supports the optional ZF8605 oil pump connection device, paired with a lubricant oil capacity of 8.4L. This setup provides continuous and efficient lubrication for internal components, effectively reducing wear, lowering failure rates, and extending the service life of the unit.
Inter-axle Differential: The inter-axle differential offers selectable torque ratio proportions of 1:1, 1:2.214, 1:2.696, or 1:3. This allows for intelligent power distribution between the front and rear axles, significantly improving traction, passability, and driving stability on diverse and challenging terrains.
Pneumatic Shifting: Equipped with 3-pneumatic shifting (operating at 6.5–10 bar) and front axle output operation with an indication switch, the system enables rapid, smooth gear changes. This enhances operational convenience, control, and overall driving safety for the vehicle.
