A pinion and ring gear are integral components of a differential system in automobiles. The pinion gear is the smaller gear that meshes with the larger ring gear.

The pinion is connected to the engine via the driveshaft, and its teeth mesh with the teeth of the ring gear, enabling it to spin. This interaction translates the rotational motion from the drivetrain into a motion that can be used by the axle to rotate the wheels.

The ring gear, also known as a crown wheel, is attached to the differential carrier or the axle in the vehicle. As its name implies, it is a large circular gear with teeth on its outer edge that mesh with the pinion gear.

Together, the pinion and ring gear help to distribute power from the engine to the axle, which then rotates the wheels, resulting in the vehicles movement.
