Drive Axle

Hub Reduction Drive Axle (The 4th Generation)

Model: QT300

Longer reliability fatigue life: Reaching max output torque of 55000Nm and reliability lifetime increased by 40%.
Higher loading capacity: Housing with unequal wall thickness, add reinforcement ribs on radius area, use box section structure for spring saddle area.
Higher gear fatigue life: Using one-piece crown gear with higher supporting stiffness.
More simplified assembly process: Using one-piece design of carrier to reduce components quantity.
