Abstract

Described is a ball bearing (3) for shafts subject to linear motion, in particular for vehicle-transmission gear-shift rods (2) held in place by a spring-biased securing element which acts radially on the rod. The invention calls for the outer bearing ring and the ball races enclosed by it to have a common radial gap through which one end of the securing element, which is in the form of a pin (4), projects and makes contact with the gear-shift rod (2). This design allows the securing element to act on the shaft in the immediate vicinity of the bearing.

Kugellager zur Abstützung von linear bewegten WellenBall bearings to support linearly moving shafts
15 Die Erfindung betrifft ein Kugellager zur Abstützung von linear beweg¬ ten Wellen, insbesondere von in Kraftfahrzeuggetrieben angeordneten Schaltstangen, die durch ein radial auf sie einwirkendes Rastelement arrtiert sind.The invention relates to a ball bearing for supporting linearly moving shafts, in particular shift rods arranged in motor vehicle transmissions, which are locked by a locking element acting radially thereon.
20 Auf solche Schaltstangen wirken nicht nur die Rastelemente, sondern in viel stärkerem Maße auch die Schaltkräfte bzw. Synchronisierkräfte ein. Daher ist es vorteilhaft, für die Schaltstangenlagerung nicht Gleitlager, sondern Wälzlager zu verwenden. Die hohen Lagerkräfte ergeben sich infolge der räumlichen Momentenbeaufschlagung.20 Not only the locking elements act on such shift rods, but also the shifting forces or synchronizing forces to a much greater extent. It is therefore advantageous to use roller bearings instead of plain bearings for the shift rod bearing. The high bearing forces result from the application of spatial moments.

Es gibt spezielle Schaltwellen, bei denen Rastelemente unmittelbar im Lagerbereich angeordnet sind, die entweder die geschaltete Gangposi¬ tion festhalten oder verhindern sollen, daß benachbarte Schaltwellen sich gleichzeitig bewegen können. In einem solchen Fall muß das LagerThere are special selector shafts in which latching elements are arranged directly in the bearing area, which are either intended to hold the shifted gear position or to prevent neighboring selector shafts from being able to move simultaneously. In such a case, the camp
30 zusätzlich für die Kräfte ausgelegt sein, die sich infolge der Arre¬ tierung ergeben.30 can additionally be designed for the forces which result from the locking.
Aus der DE-PS 15 75 504 ist ein Radialwälzlager für eine Welle be¬ kannt, die nur eine Schwenkbewegung um einen bestimmten Winkel aus- 35 führen kann. Diese Welle weist eine Aussparung auf, in die ein stab- förmiges Teil hineinragt. Aus diesem Grunde ist auch der äußere Lager¬ ring mit einer Aussparung versehen. Als Wälzkörper genügen hier Lager¬ nadeln, weil die Welle sich nicht in Achsrichtung verschieben kann. Der Erfindung liegt die Aufgabe zugrunde, ein einfach aufgebautes Lager für eine in Achsrichtung verschiebbare Welle zu schaffen, wel¬ ches eine Einwirkung einer Arretiereinrichtung auf die Welle unmittel¬ bar in deren Lagerbereich ermöglicht.From DE-PS 15 75 504 a radial roller bearing for a shaft is known which can only perform a pivoting movement through a certain angle. This shaft has a recess into which a rod-shaped part protrudes. For this reason, the outer bearing ring is also provided with a recess. Bearing needles are sufficient as rolling elements here because the shaft cannot move in the axial direction. The invention has for its object to provide a simply constructed bearing for a shaft which is displaceable in the axial direction, which enables a locking device to act directly on the shaft in its bearing area.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der äußere Lagerring und die von ihm umfaßten Kugelreihen einen gemeinsamen radialen Durchbruch aufweisen, durch den das Rastelement mit einem Ende hindurchragt und mit der Schaltstange in Kontakt steht. Die Kugelreihen können in einem mit dem Durchbruch versehenen Käfig an¬ geordnet sein. Ein solches Kugellager ermöglicht es, den Kraftaufwand beim Gangschalten zu verringern, und somit den Schaltkomfort zu erhö¬ hen.This object is achieved in that the outer bearing ring and the rows of balls encompassed by it have a common radial opening, through which the latching element protrudes at one end and is in contact with the shift rod. The rows of balls can be arranged in a cage provided with the opening. Such a ball bearing makes it possible to reduce the effort required to shift gears and thus to increase shifting comfort.
Der Durchbruch des äußeren Lagerringes oder des Lagerringes und des Käfigs kann in der Form eines Schlitzes ausgeführt sein, der sich über die gesamte axiale Länge des Lagers erstreckt. Es ist aber auch mög¬ lich, den Durchbruch in der Form einer kreisrunden, ovalen oder recht¬ eckigen Öffnung des Lagerringes bzw. des Lagerringes und des Käfigs auszuführen.The opening of the outer bearing ring or the bearing ring and the cage can be designed in the form of a slot which extends over the entire axial length of the bearing. However, it is also possible to make the opening in the form of a circular, oval or rectangular opening in the bearing ring or the bearing ring and the cage.
Bei einer Ausführung mit mehreren hintereinander angeordneten Schalt¬ stangen kann für die Schaltsicherung einer mittleren Schaltstange an dem Lager ein zu dem Durchbruch in Umfangsrichtuπg beispielsweise um 180° versetzter zweiter Durchbruch angeordnet sein. In diesem Fall ist es möglich, daß der Käfig in zwei schalenför ige Käfigteile aufgeteilt wird. Dabei können die beiden Käfigteile über ihre Borde ganz oder teilweise miteinander verbunden sein.In the case of an embodiment with a plurality of shift rods arranged one behind the other, a second breakthrough offset from the breakthrough in the circumferential direction, for example by 180 °, can be arranged on the bearing for securing a middle shift rod. In this case, it is possible that the cage is divided into two shell-shaped cage parts. The two cage parts can be connected to one another in whole or in part via their rims.
Damit der durchbrochene Käfig zu dem durchbrochenen äußeren Lagerring immer richtig angeordnet ist, kann der Käfig an dem Lagerring durch Anschlagflächen aufweisende radiale Vorsprünge gehalten sein, die sich im Bereich des Durchbruchs befinden. Diese Vorsprünge können entweder an dem Käfig befestigt sein und in den Bereich des Lagerringes hinein- ragen, oder sie können an dem Lagerring befestigt sein und in den Bereich des Käfigs hineinragen. Dabei kann die Befestigung dadurch hergestellt sein, daß die Vorsprünge einstückig mit dem Lagerring oder mit dem Käfig ausgeführt sind. Infolge der Vorsprünge ist dann ein relatives Verdrehen zwischen dem Lagerring und dem Käfig nicht mög¬ lich.So that the perforated cage is always correctly arranged with respect to the perforated outer bearing ring, the cage can be held on the bearing ring by means of radial projections which are located in the region of the opening. These projections can either be attached to the cage and protrude into the area of the bearing ring, or they can be attached to the bearing ring and protrude into the area of the cage. The attachment can be made in that the projections in one piece with the bearing ring or are carried out with the cage. As a result of the projections, relative rotation between the bearing ring and the cage is then not possible.
Da der Durchbruch des Lagerringes zu dem Rastelement lagerichtig mon¬ tiert werden muß, was z. B. durch einen Roboter geschehen kann, bietet es sich an, an einem oder an beiden Lagerringborden Markierungen vorzusehen, die mittig in dem Lagerring in axialer Verlängerung zu dem Durchbruch angeordnet sind. Das Rastelement kann als Raststift ausge- bildet sein.Since the breakthrough of the bearing ring to the locking element must be installed in the correct position. B. can be done by a robot, it makes sense to provide markings on one or both bearing ring rims, which are arranged centrally in the bearing ring in an axial extension to the opening. The locking element can be designed as a locking pin.

In einem Gehäuse 1 eines Schaltgetriebes ist eine Schaltstange 2 längsverschieblich gelagert. Hierzu dient ein Kugellager 3, dessen äußerer Lagerring einen Durchbruch aufweist, durch den ein Raststift 4 mit einem Ende hindurchragt, so daß er mit einer Anlagefläche 22 in einer in die Schaltstange 2 eingearbeiteten Ausnehmung 23 in Kontakt steht. Der Raststift 4 hat die Form einer Hülse, die von einer Feder 5 radial auf die Schaltstange 2 gedrückt wird. Die Feder ist innerhalb der Hülse, die den Raststift 4 bildet, angeordnet und stützt sich als Druckfeder mit einem Ende an dem Gehäuse 1 und mit dem anderen Ende an einer ringförmigen Anschlagkante des Raststiftes 4 ab.In a housing 1 of a gearbox, a shift rod 2 is mounted for longitudinal displacement. For this purpose, a ball bearing 3 is used, the outer bearing ring of which has an opening through which a locking pin 4 protrudes at one end, so that it comes into contact with a contact surface 22 in a recess 23 incorporated into the shift rod 2 stands. The locking pin 4 has the shape of a sleeve which is pressed radially onto the shift rod 2 by a spring 5. The spring is arranged within the sleeve which forms the locking pin 4 and is supported as a compression spring with one end on the housing 1 and the other end on an annular stop edge of the locking pin 4.
Bei der Ausführungsform des Rad alkugellagers gemäß den Figuren 2 und 3 ist in einem äußeren Lagerring 6 ein Käfig 7 mit Kugelreihen 8 angeordnet. In einem U fangsbereich des Lagers sind der Lagerring 6 und der Käfig 7 mit einem gemeinsamen Durchbruch 9 versehen, der in diesem Ausfuhrungsbeispiel rechteckför ig ist. Längs einer Rechteck¬ seite des Durchbruchs 9 ist am Lagerring 6 ein radialer Vorsprung 10 ausgebildet, der in den Bereich des Käfigs 7 hineinragt und für diesen eine Anschlagfläche aufweist. Längs der hierzu parallelen Rechtecksei- te des Durchbruchs 9 ist der Käfig 7 mit einem Vorsprung 11 versehen, der von innen nach außen radial in den Bereich des Lagerringes 6 hineinragt und ebenfalls eine Anschlagfläche hat, an der der Lagerring 6 anliegen kann. Diese Vorsprünge sichern die lagerichtige Anordnung von Käfig und Lagerring. Für die Montageorientierung des Durchbruchs 9 befindet sich in einem Bord 12 des Lagerringes 6 eine Aussparung 13.In the embodiment of the wheel ball bearing according to Figures 2 and 3, a cage 7 with rows of balls 8 is arranged in an outer bearing ring 6. In a U starting area of the bearing, the bearing ring 6 and the cage 7 are provided with a common opening 9, which is rectangular in this exemplary embodiment. A radial projection 10 is formed on the bearing ring 6 along a rectangle side of the opening 9, which protrudes into the area of the cage 7 and has a stop surface therefor. Along the parallel rectangular side of the opening 9, the cage 7 is provided with a projection 11 which projects radially from the inside outward into the region of the bearing ring 6 and also has a stop surface against which the bearing ring 6 can rest. These projections ensure the correct arrangement of the cage and bearing ring. For the assembly orientation of the opening 9 there is a recess 13 in a rim 12 of the bearing ring 6.
Bei dem Ausführungsbeispiel gemäß den Figuren 4 und 5 ist in dem äußeren Lagerring 14 und in dem Käfig 15 ein Durchbruch 16 angeordnet, der sich über die gesamte axiale Länge des Kugellagers erstreckt. Dieser Durchbruch 16 bildet also einen Schlitz in dem Lager. Auch hier ist längs einer Begrenzungsl nie des Durchbruchs 16 ein Vorsprung 10 an dem Lagerring 14 und ein Vorsprung 11 an dem Käfig 15 ausgebildet, um die relative Stellung zwichen Lagerring 14 und Käfig 15 einzuhal- ten.In the exemplary embodiment according to FIGS. 4 and 5, an opening 16 is arranged in the outer bearing ring 14 and in the cage 15 and extends over the entire axial length of the ball bearing. This opening 16 thus forms a slot in the bearing. Here too, a protrusion 10 is formed on the bearing ring 14 and a protrusion 11 on the cage 15 along a boundary line of the opening 16 in order to maintain the relative position between the bearing ring 14 and the cage 15.
Bei dem Ausführungsbeispiel gemäß den Figuren 6 und 7 ist zusätzlich zu dem Durchbruch 17 in einem Umfangsbereich des äußeren Lagerringes 18 ein zweiter Durchbruch 19 vorgesehenr der zu dem Durchbruch 17 um 180° versetzt ist. Auf diese Weise sind aus einem Käfig zwei gleiche Käfigteile 20 entstanden, die von radialen Vorsprüngen 21 des Lager- ringes 18 in ihrer Stellung gehalten werden. Der Durchbruch hat hier die Form eines Kreises. In the embodiment according to FIGS 6 and 7 is a second breakthrough r 19 are provided in addition to the aperture 17 in a circumferential region of the outer bearing ring 18 which is offset from the aperture 17 by 180 °. In this way, two identical cage parts 20 have arisen from a cage, which are supported by radial projections 21 of the bearing ringes 18 are held in position. The breakthrough here has the shape of a circle.
