Description
DEUTSCHESGERMAN
Die Erfindung bezieht sich auf eine Synchronisier- und Gangschalteinrichtung für ein Zahnräderwechselgetriebe, insbesondere für Kraftfahrzeuge, mit durch einen Ziehkeil betätigten Kugeln als Schaltelemente und mit einem Spreizring zum Synchronisieren.The invention relates to a synchronizing and gear shifting device for a gear change transmission, especially for motor vehicles, with balls operated by a draw key as switching elements and with an expanding ring for synchronization.
Bei dieser bekannten Einrichtung wird der Spreizring mittels des Ziehkeils gespannt und an die zu synchronisierenden Getriebeteile angepreßt. Das Spannen und Anpressen erfolgt jedoch durch die Schaltkraft, die dazu bei manchen Getriebeausführungen zu gering ist.In this known device, the expansion ring is tensioned by means of the draw wedge and attached to the one to be synchronized Gear parts pressed on. However, the clamping and pressing is done by the switching force, which is too low for some gear versions.
Die Aufgabe der Erfindung besteht in der Schaffung einer Synchronisier- und Gangschalteinrichtung, die die Schaltkraft zum Synchronisieren nicht benötigt.The object of the invention is to provide a synchronizing and gear shifting device which the switching force for synchronization is not required.
Die Erfindung löst diese Aufgabe dadurch, daß der Spreizring mit einer konstanten Vorspannung mit dem einen Getriebeteil in Reibungsverbindung steht und mit dem zu schaltenden anderen Getriebeteil durch Riegelglieder verbindbar ist.The invention solves this problem in that the expansion ring with a constant bias the one gear part is in frictional connection and with the other gear part to be shifted is connectable by locking members.
Damit bei jeder praktisch vorkommenden Relativdrehzahl geschaltet werden kann, hat der Spreizring längliche Taschen, in die die Riegelglieder einschiebbar sind.The expansion ring has so that it is possible to switch at every practically occurring relative speed elongated pockets into which the locking links can be inserted.
Bei einer Synchronisier- und Schalteinrichtung, bei der zwischen zwei Kugelreihen ein axial verschiebbares Riegelglied zum Ausschalten der auf die Kugeln einwirkenden Fliehkräfte vorgesehen ist, sind die Spreizringe mit dem durch die Kugeln axial verschiebbaren Riegelglied kuppelbar. Es ist auch möglich, die Synchronwirkung der Spreizringe dadurch zu erhöhen, daß der Spreizring und der mit ihm in Reibungsverbindung stehende Getriebeteil je eine wellige Oberfläche haben.In the case of a synchronizing and switching device in which an axially displaceable one between two rows of balls The locking element is provided to switch off the centrifugal forces acting on the balls Spreader rings can be coupled to the locking member which is axially displaceable by the balls. It is also possible, to increase the synchronous effect of the expanding rings that the expanding ring and with it in Frictionally connected transmission parts each have a wavy surface.
Die Erfindung ist in Abb. 1 bis 3 beispielsweise dargestellt. The invention is shown in Figs. 1 to 3, for example.
Abb. 1 zeigt eine Getriebewelle 1 und in bekannter Weise angeordnete Kugeln 2, die durch einen Ziehkeil 3 in die Kuppelstellung gebracht werden. Die Riegelglieder 4, z. B. Stifte oder eine oder mehrere Kugeln, sind ebenso wie die Kugeln 2 in der Getriebewelle 1 radial verschiebbar im Bereich eines Spreizringes 6 angeordnet, der mit einer Vorspannung in den Getriebeteil 5 eingebaut und mit länglichen Taschen 7 versehen ist, in die die Riegelglieder 4 einrasten. 4-5Fig. 1 shows a gear shaft 1 and balls 2 arranged in a known manner, which are brought into the coupling position by a draw key 3. The locking members 4, z. B. pins or one or more balls, like the balls 2 in the gear shaft 1 are arranged radially displaceable in the area of an expansion ring 6, which is installed with a preload in the gear part 5 and provided with elongated pockets 7 into which the locking members 4 snap into place. 4-5
Diese Taschen sind so lang, daß die Riegelglieder auch bei hohen Relativdrehzahlen sicher einrasten. Wird der Ziehkeil 3 axial verschoben, so bewirken zunächst die Riegelglieder 4 die Verbindung des vorgespannten Spreizringes 6 mit der Welle 1. Die Masse des Spreizringes ist dabei so gering, daß ein wahrnehmbarer Schaltschlag durch die plötzliche Verbindung mit der Welle nicht eintritt. Durch die Vorspannung des Spreizringes wird jedoch in bekannter Synchronisier-These pockets are so long that the locking links lock securely into place even at high relative speeds. If the draw key 3 is axially displaced, the locking members 4 initially cause the connection of the prestressed Expansion ring 6 with the shaft 1. The mass of the expansion ring is so small that a noticeable Switching shock does not occur due to the sudden connection with the shaft. Because of the bias of the expansion ring is, however, in the known synchronizing

Weise bewirkt, daß die Massen des Getriebeteils 5 und die damit in Verbindung stehenden Massen infolge der Reibung des Spreizringes allmählich mit der Getriebewelle 1 auf gleiche Drehzahl gebracht werden. Wenn dieses Angleichen an die Drehzahl erfolgt ist, drückt der Ziehkeil die Kugeln 2 in die Kugeltaschen, in die sie aber erst dann einrasten können, wenn die Relativdrehzahl zwischen der Getriebewelle 1 und dem Getriebeteil 5 genügend herabgesetzt ist.Way causes the masses of the transmission part 5 and the masses associated therewith as a result the friction of the expansion ring can be gradually brought to the same speed with the transmission shaft 1. When this adjustment to the speed has taken place, the draw key presses the balls 2 into the ball pockets, But in which they can only engage when the relative speed between the gear shaft 1 and the gear part 5 is sufficiently reduced.
Abb. 2 zeigt ebenfalls einen in bekannter Weise angeordneten Ziehkeil 3', die Getriebewelle 1' und die Schaltkugeln 2'. Der Spreizring 11 ist unmittelbar im Getriebeteil 12 mit Vorspannung eingebaut. Die Vorspannung ist so gewählt, daß die Eigenvorspannung des Spreizringes zusammen mit der durch die Riegelglieder erzeugten Radialkomponente das gesamte Getriebedrehmoment übertragen kann. Bei dieser Ausführungsform kann zwischen dem Spreizring 11 und dem Getriebeteil 12 eine wellige Oberfläche zur besseren Mitnahme vorgesehen sein.Fig. 2 also shows a draw key 3 'arranged in a known manner, the gear shaft 1' and the Switching balls 2 '. The expansion ring 11 is installed directly in the gear part 12 with preload. The bias is chosen so that the self-tensioning of the expansion ring together with that of the locking members generated radial component can transmit the entire transmission torque. In this embodiment can between the expansion ring 11 and the gear part 12 to a wavy surface better entrainment should be provided.
Auch bei dieser Ausführungsform ist die Masse des Spreizringes möglichst gering zu wählen, damit ein wahrnehmbarer Schaltschlag durch das plötzliche Mitnehmen des Spreizringes nicht auftreten kann. Durch die längliche Ausbildung der Kugeltaschen ist dafür Sorge getragen, daß die Riegelglieder bei jeder vorkommenden Relativdrehzahl den Spreizring sofort mit der Welle verbinden. Wenn bei den anzugleichenden Massen durch die plötzliche Drehzahländerung ein größeres Drehmoment als das Getriebedrehmoment entsteht, dann tritt ein Durchrutschen des Synchronringes, d. h. ein Nachsynchronisieren, ein.In this embodiment, too, the mass is The expansion ring should be chosen as small as possible, so that a noticeable switching shock due to the sudden removal of the expansion ring cannot occur. This is due to the elongated design of the ball pockets Care is taken that the locking members immediately move the expansion ring with every occurring relative speed connect the shaft. If the masses to be adjusted are caused by the sudden change in speed If the torque is greater than the gearbox torque, then the synchronizer ring will slip, d. H. a resynchronization, a.
