What is the detailed introduction of Subaru's four-wheel drive system?

[StTalia]

Detailed introduction of Subaru's four-wheel drive system: 1. Full-time four-wheel drive structure: Subaru has added a bevel gear-type central differential to the transfer case, with a rigid gear connection. The electronically controlled multi-plate differential inside is only responsible for adjusting the torque distribution between the front and rear axles and cannot separate them. Therefore, the front and rear axles always receive power. Under normal conditions, the power distribution between the front and rear wheels is 70:30, making it a true full-time four-wheel drive structure. 2. Active Torque Distribution Full-time Four-Wheel Drive System: The Active Torque Distribution Full-time Four-Wheel Drive System transmits power directly from the transmission to the central differential in the transfer case, which then distributes it to the front and rear axles via a multi-plate clutch. The electronically controlled multi-plate differential receives commands from the computer and adjusts torque distribution in real-time based on road conditions, offering better reliability and practicality.
