Transfer Case Gear Description

A transfer case gear is a special gear system that distributes engine power to the front and rear axles in four-wheel drive (4WD) and all-wheel drive (AWD) vehicles. It shares the torque from the transmission evenly or variably between the two axles according to the required traction.

The Task of the Distribution Box Gear System

✔ Provides Torque Distribution - Transmits power to the front and rear axles.

✔ Increases Traction - Provides maximum grip in challenging road conditions.

✔ Provides Different Driving Modes - Provides different options such as 2WD, 4WD, low and high gear modes.

Provides Synchronization - Balances the rotational speeds of the front and rear wheels, ensuring smooth vehicle progress.

Distribution Box Gear Types

- Spur Gears → More robust and simple mechanism.

- Helical Gears → Provides quiet and efficient power transmission.

- Chain Transfer Case → Lightweight and quiet, common in AWD systems.

- Planetary Gears → Compact and efficient, often used in advanced 4WD systems.
