What is a Differential Coupling Assy?

The differential coupling is a vital component in a vehicle's drivetrain, designed to allow the wheels to rotate at different

speeds while maintainin power transfer from the engine. This is particularly important during turns, where the outer wheels travel a longer distance than the inner wheels. The differential coupling achieves this by using a set of gears that distribute

torque to the wheels, enabling smooth and efficient handling. When the vehicle turns, the differential allows the outer

wheel to rotate faster than the inner wheel, preventing tire wear and enhancing stability.

Additionally, it plays a crucial role in improving traction by ensuring that power is effectively distributed to the wheels,

especially in varying road conditions. Understanding the function and operation of the differential coupling is essential for

maintaining optimal vehicle performance and ensuring a safe driving experience.
