Abstract

A wheel spoiler arrangement, encompassing: a wheel spoiler carrier; a wheel spoiler received displaceably relative to the wheel spoiler carrier between inactive and active positions constituting operating positions; a motion guidance system between the carrier and the spoiler, a drive system to drive the spoiler between its operating positions, and an overload coupling that transfers force in a direction from the spoiler to the drive system up to a predetermined limit load; the overload coupling having a shiftable structure that is shiftable, between an effective position into which the structure is preloaded in a force-transferring engagement and a passive position in which position the force-transferring engagement is not possible; the shiftable structure being shiftable from the effective position into the passive position upon exceedance of the limit load resulting from a force acting on the spoiler.
