<p>The invention relates to a parking brake control device for vehicles. Said device transforms a rotation movement into a translation movement and consists of a first disk (10), which is controlled in rotation but fixed in translation, and a second disk (14), which is fixed in rotation but free in translation; both disks contain concave areas that face one another (40). A ball (24) is enclosed between two of the corresponding concave areas of the first and second disks. The rotation of the first disk causes the ball to move on the corresponding concave area, thereby causing the second disk to move in translation. All of the concave areas of at least one of the disks contain a guide strip (42) for the corresponding ball.</p> |
