Viscous Coupling

A Viscous Coupling is a device used in all-wheel-drive (AWD) and four-wheel-drive (4WD) systems to distribute torque between axles.
It engages when slip occurs between axles, regulating torque distribution for optimal traction and stability.
The Viscous Coupling aids in maintaining traction by distributing power to the wheels with the most grip, enhancing overall vehicle stability.
The Viscous Coupling is typically integrated into the transfer case or differential of AWD and 4WD systems.
Drivetrain engineers and designers incorporate Viscous Couplings to improve traction and handling in specific vehicle drivetrain configurations.
The Viscous Coupling reacts to differences in wheel speed, allowing power to transfer between axles, enhancing traction and stability on varying surfaces.
