Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezweckt, die Vorteile einer gewöhnlichen Bandbremse auszunutzen, dabei aber die auftretenden großen Bremskräfte S1 und S2 der beiden Bandteile, die sonst auf die Bremsscheibenwelle und den Befestigungspunkt des Bremsbandes übertragen werden, auf dem kürzesten Wege in sich selbst zu vernichten. Dies wird erreicht durch Verbindung der Bremsbandenden mit einer Daumen- oder Exzenterscheibe E (Fig. ι und 2). Durch Drehen dieser Scheibe E mittels eines Handhebels H oder dergl. in der eingezeichneten Richtung wird die Achse G in ihrer Führung F nach links verschoben und das Bremsband gespannt. Nur die abzubremsende Umfangskraft muß von der Führung F aufgenommen werden, während in der Richtung der Achse der Bremsscheibe und der Exzenterscheibe keine Kräfte nach außen übertragen werden.The aim of the invention is to utilize the advantages of an ordinary band brake, while at the same time destroying the large braking forces S 1 and S 2 of the two band parts, which are otherwise transmitted to the brake disc shaft and the fastening point of the brake band, in the shortest possible way. This is achieved by connecting the ends of the brake band with a thumb or eccentric disk E (FIGS. 1 and 2). By turning this disc E by means of a hand lever H or the like in the direction shown, the axis G is shifted to the left in its guide F and the brake band is tensioned. Only the circumferential force to be braked has to be absorbed by the guide F , while no forces are transmitted to the outside in the direction of the axis of the brake disk and the eccentric disk.
Die im Berührungspunkte A der Bremsscheibe B und des Daumens E auftretende Reibung R vermindert die zum Bremsen erforderliche Kraft K am Handhebel; diese Verminderung kann durch entsprechende Form der Exzenterscheibe E (Vergrößerung des Winkels G A W) so weit geführt werden , daß die Bremse selbstsperrend wird, also K= Null wird.The friction R occurring at the contact point A of the brake disc B and the thumb E reduces the force K required for braking on the hand lever; this reduction can be carried out by a corresponding shape of the eccentric disk E (enlargement of the angle G AW) so far that the brake becomes self-locking, that is, K = zero.
