System to be coupled to a cardan shaft, related cardan shaft and operation method of said system

Abstract

A cardan shaft slip distance change detection system for determining the amount of length change of the cardan shaft, including a moveable element and a stationary element associated with a telescopic approach to compensate for the change of distance caused by the vehicle's axle movements. At least two conductive elements are configured as one of them connected to a fixed point, another to the moveable element. A power element is provided to supply power to at least one of the conductive elements. A detection unit measures the electrical value change provided by the electrical interaction between the conductive elements and correlating it with the distance between the conductive elements.

Dependencies are inferred from the claim text.
