Device for the automatic stepped cable length adjustment of bowden cable system

摘要

A device for the automatic, stepped cable length compensation of a Bowden cable system in which a spring-tensioned cable is guided. The spring is supported between a part on the housing side and a part on the Bowden tube side displaceable relative thereto and having several detent elements resiliently pretensioned in the direction of the sleeve face of the part on the Bowden tube side. During displacement of the part on the Bowden tube side the detent elements engage in succession in front of the end face of this part so that a resetting movement of the part on the Bowden tube side is prevented. Each detent element is allocated a pair of stops between which the detent, element is mounted for restricted axial displacement. In another embodiment, at least a pair of spaced stops correspond with an intermediate part mounted between the part on the housing side and the part on the Bowden tube side which is displaceable a restricted amount so that a cable length compensating detent process can only take place after overcoming a predetermined setting movement between the part on the housing side and the part on the Bowden tube side. The parts which can be displaced a restricted amount are detent elements which have an axial spacing relative to each other. The pair of spaced stops is a constituent part of the part on the Bowden tube side between which engages a keyed locking element of the intermediate part.
