What is ment by fluid axle shaft?

A fluid axle shaft refers to a component in certain types of machinery, particularly in hydraulic systems, where the axle is designed to transmit power while allowing for the flow of hydraulic fluid. This design helps in reducing friction and wear, as the fluid acts as both a lubricant and a medium for power transmission. The fluid dynamics within the shaft can enhance performance and efficiency, particularly in applications like automotive or industrial machinery.
