Morphology
The term names the literal combination of its parts: a wheel together with an axle. A B1 learner who knows 'wheel' and 'axle' can readily infer this is a simple machine/device composed of those two elements and used for motion or lifting, so the meaning is directly derivable and cross-linguistically transparent.
Etymology
Wheel and axle names a simple machine used for lifting: picture a big wheel with a smaller axle in the middle and a rope wrapped around the axle. When you turn the wheel, the rope winds on the axle and pulls up a heavy bucket, so the term describes a device that helps 'lift' or 'move' things.
