The primary function is to allow the front wheels to rotate at different speeds during cornering while distributing torque from the transmission to both wheels, preventing tire scrubbing and ensuring smooth handling.
Common materials include alloy steel and cast iron for the housing, and hardened steel gears. The housing may be aluminum die-casting (e.g., ADC12) and gears often use carburized steel like 20CrMnTi.
Rated torque capacity typically ranges from 1500 to 3000 N·m, and axle ratio from 3.5 to 4.5. These values must be matched to the engine torque and vehicle weight.
Specifications such as torque capacity, gear precision, and seal types are application-specific. Verification ensures the differential meets the requirements of the specific vehicle model and operating conditions.
