Die Erfindung betrifft eine Kupplung mit Kupplungsbacken, die durch Schraubenanzug gegen das Kupplungsgehäuse gedrückt werden und durch an diesen Schrauben angreifende Gelenke mit einer in der Längsrichtung der Kupplung verschiebbaren, das Einrücken bewirkenden Büchse in Verbindung stehen. Bei dieser Kupplung soll nun die Abnutzung der Kupplungsbacken in demselbenThe invention relates to a clutch with clutch shoes, which by screw tightening are pressed against the clutch housing and by engaging these screws Joints with a displaceable in the longitudinal direction of the coupling, the Engaging causing bush in connection. With this coupling, the Wear of the clutch shoes in the same

ίο Maße, wie sie vor sich geht, ausgeglichen werden, so daß die Backen fast bis zur vollständigen Abnutzung verwendet werden können. Zu diesem Zweck ist die den Schraubenanzug bewirkende Büchse als Mutter für eine mit Schraubengewinde versehene zweite Büchse ausgebildet, die unter . der Einwirkung einer Druckfeder , steht. Durch Verstellen der als Mutter dienenden Büchse auf der zweiten Büchse kann also die allmähliche Abnutzung der Backen ohne Änderung der Spannung der Feder ausgeglichen werden.ίο Measures as it goes on, balanced so that the jaws can be used until they are almost completely worn out. For this purpose is the den Screw tightening bushing as a nut for a screw-threaded one second sleeve formed, the under. the action of a compression spring. By adjusting the one serving as a mother The sleeve on the second sleeve can therefore avoid the gradual wear of the jaws Change in the tension of the spring can be compensated for.

Diese Verstellung zum Ausgleich der Abnutzung der Backen ist jedoch nur in engen Grenzen möglich. Um nun die Abnutzung der Backen bis auf das äußerste Maß zu ermöglichen, sind größere Verstellungen notwendig , insbesondere nachdem eine weitere Verstellung durch die Büchse nicht mehr möglich ist. Es muß dann diese Büchse in ihre Anfangsstellung wieder zurückgebracht werden können, ohne daß die Stellung der Backen zum Kupplungsgehäuse geändert wird. Dies wird dadurch erreicht, daß die Gelenke, die die als Mutter dienende Büchse mit den die Backen andrückenden Schrauben verbinden, an Scheiben angreifen, die in gleichen Abständen voneinander, mehrere Löcher tragen, so daß die Stellung des Angriffspunktes der. Gelenke an diesen Scheiben entsprechend der Abnutzung der. Backen geändert werden kann.However, this adjustment to compensate for the wear on the jaws is only limited Limits possible. In order to allow the jaws to wear out to the utmost, major adjustments are necessary, especially after another Adjustment through the bush is no longer possible. It must then be in this box their initial position can be brought back without affecting the position of the Jaws to the clutch housing is changed. This is achieved by the joints, which connect the bushing, which serves as a nut, to the screws pressing the jaws, attack discs that have several holes at equal distances from each other, so that the position of the point of attack. Joints on these discs according to the Wear and tear of the. Baking can be changed.

In der Zeichnung ist die neue Kupplung in einem Ausführungsbeispiel zur Darstellung gekommen.In the drawing, the new clutch is shown in an exemplary embodiment came.

Die Kupplung besteht in bekannter Weise aus zwei metallischen Backen α und b, von denen jede einen Halbkreis bildet und die im Innern eines Gehäuses c sitzen, das mit dem Schwungrad des Motors einen Teil bildet. Jede Backe trägt zwei Zapfen d, an denen Büchsen e sitzen, die je nach der Kupplungshälfte, zu der sie gehören, im Innern ent- The coupling consists in a known manner of two metal jaws α and b, each of which forms a semicircle and which sit inside a housing c which forms part of the flywheel of the engine. Each jaw has two pins d on which bushes e sit which, depending on the coupling half to which they belong, are located on the inside.

Claims

wear neither right-hand nor left-hand threads; two screws f, which have a right-hand thread or left-hand thread, sit in the sleeves e in such a way that, as soon as they are rotated in the direction of the arrows in FIG. 2, they tend to push the two jaws a and b against the inside of the housing c to press. The rotation of the screws f takes place through circular disks g in which there are many holes at a certain, equal distance from one another; they are connected to the adjusting sleeve k by means of four steering rods h which engage in the holes in the disks by means of pins. This has screw thread and forms the nut to a second sleeve η and is held in place by a lock nut 0. The bushing η is adjusted by two rods p which engage a ring. The ao ring q sits between two rows of balls r in a recess in the sleeve n. The pressure required for coupling is obtained by a spring s which is screwed against a ring that is screwed onto the sleeve η and delimits the recess for the ring q on the other side works. The shaft t of the coupling carries a cross head 772, which sits on a square part of the shaft. The two arms of the head each have a rectangular hole for receiving a wedge or bolt 11, which sits in arms ν of the jaws a and b. The bolts u have a certain clearance in the holes of the crosshead m in the radial direction so that the jaws α and b can make the movement necessary for coupling and uncoupling. The shaft t is held at its end by a ball bearing w, which is located in a small recess in the end of the shaft χ of the motor. It is easy to see how the clutch works. The jaws α and b are against the sleeve c with a pressure sufficient for transmission by the spring. pressed which, acting on the sleeve η, brings the jaws into contact with the housing by means of the sleeve k, handlebars h, washers g and screws f. The force is then transmitted from the shaft χ of the motor to the shaft t through the jaws α and b, which, through the bolts u, take along the crosshead m sitting on the shaft t. If you want to uncouple, it is sufficient to move the bushing η on the shaft x by means of the rods ρ, against the action of the spring s. The parts then assume the position shown in FIG. 3, the disks g have made a partial rotation, as a result of which the screws f have brought the jaws a and b closer together, a movement which as a result. the clearance of the bolts in the bearings of the crosshead is possible. The wear of the jaws α and b can gradually be compensated for in the following way: As soon as the jaws are not yet worn, the parts assume the position shown below in FIG. To the extent that wear now occurs, the bush k can be pushed forward on the bush η until the former hits the hub of the crosshead m; during this displacement, the ring q still maintains its position, eliminating any change in the tension of the spring. is prevented due to the independence of the sleeves k and η from each other, which are connected to each other by screw connections. As soon as the wear of the jaws is such that the bush k abuts against the hub of the crosshead m, the bush can be brought back into the initial position shown in the lower part of FIG. 2 and the pins i of the handlebars will then be brought inserted into another hole of the disks g. After this regulation of the clutch, it works exactly as it did before it was worn. As a result of this arrangement, the jaws α and b can be used until they are completely worn out without ever having a bad effect. The device described allows not only a slight change in the position of the jaws, but also completely prevents any irregular wear of the same and jamming in the threads of the screws f as a result of the arrangement of the bushes e, which are the nuts for these screws and which are at d are hinged to the jaws α and b '. It is precisely this articulated arrangement that is absolutely important for the regulation and for the correct operation of the jaws. Godfather nt-A ν Proverbs:
