pyöräluiston

Pyöräluisto, often translated as "wheel slip" or "tire slip," refers to a situation where a rolling wheel rotates at a different speed than its linear velocity would suggest. This can occur in various contexts, most notably in automotive and cycling applications.

In automotive contexts, pyöräluisto is a critical concept in understanding vehicle dynamics. When a wheel locks up during braking, it stops rotating but continues to slide along the road surface, resulting in significant pyöräluisto. This uncontrolled sliding reduces steering effectiveness and increases stopping distance. Anti-lock braking systems (ABS) are designed to prevent excessive pyöräluisto by modulating brake pressure, allowing the wheels to maintain some rotation while still decelerating effectively. Similarly, during acceleration, if the engine's torque exceeds the available traction between the tire and the road, the driven wheels can spin faster than the vehicle is moving, causing pyöräluisto. This can lead to a loss of traction and control.

In cycling, pyöräluisto can occur when a cyclist applies excessive force to the pedals, causing the rear wheel to spin without propelling the bicycle forward, especially on slippery surfaces like ice or wet gravel. Similarly, aggressive braking with a bicycle can lead to the wheels locking up and sliding, creating pyöräluisto. This significantly impairs the rider's ability to steer and stop safely. Understanding the limits of traction and avoiding excessive braking or acceleration are key to preventing pyöräluisto for cyclists.
