Ajopyöriä

Ajopyöriä is a Finnish term that translates to "driving wheels" or "drive wheels." It refers to the wheels of a vehicle that are powered by the engine and transmit torque to the ground, enabling movement. In a typical vehicle, these are the wheels connected to the drivetrain.

The concept of ajopyöriä is fundamental to understanding vehicle mechanics. The number of ajopyöriä determines whether a vehicle is two-wheel drive, four-wheel drive, or all-wheel drive. In a two-wheel drive system, either the front or rear set of wheels are the ajopyöriä. A four-wheel drive system typically utilizes all four wheels as ajopyöriä, though some systems can selectively engage them.

The design and material of ajopyöriä are crucial for traction and performance. Tires, mounted on the ajopyöriä, are specifically designed to provide grip on various surfaces. The rotation of the ajopyöriä, against the resistance of the road, is what propels the vehicle forward or backward. Understanding the function of ajopyöriä is essential for anyone interested in automotive engineering or the operation of vehicles.
