DuraMac ZQC2800 Wheeled Vehicle Transfer Case
The ZQC2800 is a heavy-duty transfer case designed for wheeled vehicles, engineered to handle the most demanding operating conditions. It delivers a maximum input torque of 32000Nm and a maximum input speed of 2800rpm, with an input-output center distance of 400mm, ensuring reliable and efficient power transmission.
This unit offers flexible speed ratios: 1.11 for on-road high gear and 2.37 or 1.47 for off-road low gear, selectable via 3-pneumatic shifting. It features front axle output with an indication switch and an inter-axle differential with selectable torque ratio proportions of 1:2.13 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 11L, and a total weight of 498kg, it balances robust durability and operational efficiency. An external lubricant oil cooler can be connected as an optional unit, and the input flange is available in T180 (ISO8667) specification.
Advantages of ZQC2800 Wheeled Vehicle Transfer Case
High Loading Capacity:The ZQC2800 transfer case delivers a maximum input torque of 32000Nm and a maximum input speed of 2800rpm, with an input-output center distance of 400mm. 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 features a lubricant oil capacity of 11L and supports an optional external lubricant oil cooler. This setup provides efficient heat dissipation and continuous 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 1:2.13 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.
