👉 The term "cogwheel" refers to a wheel or axle that is used in a mechanical system, particularly one where the wheels are connected by a gear train. The idea behind this concept lies in the fact that each wheel has its own independent motion and rotation, allowing for precise control of the vehicle's movement. In a cogwheels system, each wheel is attached to a gear or pinion, which is a mechanism used to transmit power from one wheel to another through an internal gear.
