Abstract
(DE)
Bei einer Schalteinrichtung für ein mehrgängiges Zahnräder-Wechselgetriebe eines Kraftfahrzeugs werden über eine zentrale Wähl- bzw. Schaltwelle (2) Schaltgassen durch deren Verdrehung angewählt und Gangstufen durch deren anschließende Axialverschiebung geschaltet. Die Wähl- bzw. Schaltwelle (2) ist über Wälzkörper drehfest und axial verschiebbar in einer Nabe (4) einer hebelartigen Wählschwinge (3) geführt. Zur Vermeidung von Spiel zwischen der Nabe (4) und der Wähl- bzw. Schaltwelle (2) in Umfangsrichtung und in radialer Richtung sind in einem zwischen Nabe (4) und Wähl- bzw. Schaltwelle (2) angeordneten Käfig (13) mehrere in axialer Richtung verlaufende Reihen von Kugeln (12) angeordnet, die mit einem Teil ihrer Oberfläche formschlüssig in Führungsnuten (10 und 11) sowohl der Nabe (4) als auch der Wähl- bzw. Schaltwelle (2) eingreifen (Fig. 1).
(EN)
In a gearshift device for a multiple-gear change box in motor vehicle, gearshift channels are selected by turning a central selector shaft (2) and gears are then shifted by moving the shaft axially. The selector shaft (2) is guided by roller bodies in a non-rotating, axially mobile manner in the hub (4) of a lever-type selector rocker (3). To prevent backlash between the hub (4) and the selector shaft (2) in the peripheral and radial directions, several axially aligned rows of balls (12) arranged in a cage (13) between the hub (4) and the selector shaft (2) interlock, with part of their surface, with guide grooves (10 and 11) in both the hub (4) and the selector shaft (2) (fig.1).
(FR)
Dans un dispositif d'embrayage d'une boîte de vitesses à engrenages à vitesses multiples d'un véhicule à moteur, des couloirs de sélection sont sélectionnés par torsion d'un arbre (2) central de sélection ou d'embrayage, les différentes vitesses étant ensuite embrayées par déplacement axial dudit arbre. L'arbre de sélection ou d'embrayage (2) est guidé sur des corps roulants de manière à ne pas tourner et à pouvoir se déplacer axialement dans le moyeu (4) d'une manivelle oscillante de sélection (3) similaire à un levier. Afin d'éliminer le jeu entre le moyeu (4) et l'arbre de sélection ou d'embrayage (2) dans les sens radial et circonférentiel, plusieurs rangées axiales de billes (12) agencées dans une cage (13) située entre le moyeu (4) et l'arbre de sélection ou d'embrayage (2) s'engagent par liaison de forme, avec une partie de leur surface, dans des rainures de guidage (10 et 11) du moyeu (4) et de l'arbre de sélection ou d'embrayage (2) (Fig.1).
