Abstract

A wire rope system for supporting an opening movement and a closing movement of a tailgate of a vehicle or a trailer, the wire rope system comprises:

a guide cylinder configured to be arranged within a side board wall or within a tailgate of a vehicle or a trailer, and comprising a front end portion with an opening and a back end portion;a compression spring arranged within the guide cylinder, and having a front end and a back end; anda plunger element configured to be movable axially within the guide cylinder;the compression spring being attached with its front end to the front end portion of the guide cylinder and being attached with its back end to the plunger element;a wire rope extending through the opening in the front end portion of the guide cylinder, and comprising a back end attached to the plunger element and a front end to be attached to a tailgate or a side board wall of a vehicle or a trailer;wherein the plunger element comprises a slide membrane element configured such that its circumferential edge abuts to the inner wall of the guide cylinder, thus separating the inner space of the guide cylinder into a back air chamber between the rear side of the slide membrane element and the back end portion of the guide cylinder, and into a front air chamber between the front side of the slide membrane element and the front end portion of the guide cylinder;wherein an air flow regulating opening is arranged within the back air chamber and connects the back air chamber to the exterior side of the guide cylinder; andwherein the slide membrane element is configured such that during movement towards the front end portion of the guide cylinder air flow from the front air chamber between its circumferential edge and the inner wall of the guide cylinder to the back air chamber is blocked or reduced, thus exerting a damping function to the movement of the wire rope and reducing the opening speed of the tailgate.
