Morphology

driving + belt

The phrase is compositionally built: 'driving' (producing or transmitting motion/force) modifies 'belt' (a loop that transmits power), so the combined meaning 'a belt that transmits motion and power' is directly derivable from its parts. This modifier+noun structure is a regular, cross-linguistically common pattern, so a B1 learner who knows both constituent senses would readily understand the MWE.

Etymology

Driving belt comes from early machines where a belt wrapped around a motor pulley and did the 'driving' by turning and moving other parts. So, the name means 'a belt that moves and gives power from the motor to other parts of a machine'.
