Abstract

The control lever (7) has a ball and socket joint (6) mounted solid to the cabin floor (4) and is extended (7a) through the floor to another ball and socket joint (8). A regulatable length reaction-rod (18), ball joints (15,17,19) and slide (9), allow the linkage to slide in a rectangular support sleeve (16) fixed to the vehicle cabin floor (4). The linkage rotation axis (10) is close to the cabin rotation axis (2) so that movements of the lever are transmitted directly to the command rod (11) connected to the gearbox (13) without rotation of the command rod.

It is therefore a continuous type control, all the components being integral with the cabin with the exception of the connection point on the gearbox this in order to avoid tensions during the movement between the chassis and the cabin .

Conformément à la présente invention, le levier de commande est prolongé du coté opposé à la rotule par un bras portant une rotule qui est montée de façon articulée dans un boîtier solidaire de l'une des extrémités d'un coulisseau dont l'autre extrémité est articulée sur une barre de commande reliée à la botte de vitesses, ledit coulisseau portant dans sa partie médiane une rotule qui est montée coulissante et oscillante dans un manchon de support i:ixé au plancher de la cabine du véhicule, ledit coulisseau étant relié au plancher de la cabine du véhicule par une barre de réaction au moyen d'articulations à rotule. According to the present invention, the control lever is extended on the side opposite to the ball joint by an arm carrying a ball joint which is articulated in a housing integral with one end of a slide whose other end is articulated on a control bar connected to the gear boot, said slider carrying in its middle part a ball joint which is slidably and oscillating mounted in a support sleeve i: fixed to the floor of the vehicle cabin, said slider being connected to the floor from the vehicle cab by a reaction bar by means of ball joints.

Ce dispositif a pour originalité de supprimer ce.rtains inconvénients des commandes de boite de vitesses à distance, à savoir les jeux dans les différentes articulations la complexité afférente a de telles réalisations, l'entretien périodique, notamment le graissage. This device has the originality of eliminating ce.rtains drawbacks of remote gearbox controls, namely the play in the different joints the complexity of such achievements, periodic maintenance, including lubrication.

D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description qui va suivre d'un mode de réalisation et en se référant aux dessins annexés, sur lesquels la figure unique est une vue en élévation d'un mode de réalisation d'un dispositif de commande de boite de vitesses suivant l'invention.  Other characteristics and advantages of the invention will be better understood on reading the following description of an embodiment and with reference to the accompanying drawings, in which the single figure is an elevational view of a mode. for producing a gearbox control device according to the invention.

A la figure unique, on a représenté de façon schématique le chassies 1 du véhicule sur lequel est montée pivotante autour d'un axe 2 la cabine 3 du véhicule, dont le plancher 4 reçoit un boîtier à rotule 5 en matière plastique au to lubrifié fixé sur le plancher au moyen de vis et d'écrous.Dans le boîtier 5, est montée sans jeu une rotule 6 solidaire d'un levier 7 de commande de boîte de vitesses qui est prolongé à sa partie inférieure du côté opposé à la rotule par un bras 7a présentant à son extrémité libre une rotule qui est montée dans un boîtier rotule 8 prserti en matière plastique autolubrifiéequi est prévu à l'une des extrémités d'un coulisseau 9 dont l'autre extrémité est articulée autour d'un axe 10 sur l'une des extrémités d'une barre de commande bl dont l'extrémité 12 est reliée de façon connue à un organe d'une boîte de vitesses 13. In the single figure, there is shown schematically the casings 1 of the vehicle on which is pivotally mounted around an axis 2 the cabin 3 of the vehicle, the floor 4 of which receives a ball joint housing 5 of plastic material with fixed lubricated to on the floor by means of screws and nuts. In the housing 5, is mounted without play a ball joint 6 secured to a gearbox control lever 7 which is extended at its lower part on the side opposite the ball joint an arm 7a having at its free end a ball joint which is mounted in a ball joint box 8 prserti in self-lubricating plastic which is provided at one end of a slide 9 whose other end is articulated around an axis 10 on one of the ends of a control bar bl whose end 12 is connected in a known manner to a member of a gearbox 13.

L'axe d'articulation 10 du coulisseau sur la barre de commande de boite de vitesses est situé proximité de l'axe d'articulation 2 de la cabine sur le chassis du véhicule. The axis of articulation 10 of the slide on the gearbox control bar is located near the axis of articulation 2 of the cabin on the chassis of the vehicle.

La liaison entre le coulisseau 9 et la barre li est assurée par une douille a aiguille 14 montée a l'extrémité du coulisseau 9. Dans sa partie médiane, le coulisseau 9 comporte une rotule 15 en matière plastique surmoulée qui est montée coulissante et oscillante dans un manchon rectiligne 16 de support fixé au plancher 4 de la cabine. The connection between the slider 9 and the bar li is ensured by a needle bushing 14 mounted at the end of the slider 9. In its middle part, the slider 9 comprises a ball joint 15 of overmolded plastic material which is slidably mounted and oscillating in a rectilinear sleeve 16 for support fixed to the floor 4 of the cabin.

Entre la rotule 15 et la rotule 8 d l'extrémité d'une partie du coulisseau 9 disposée coaxialement au manchon 16, est fixée une rotule qui est montée dans un boîtier à rotule 17 solidaire de l'une des extrémités d'une barre de réaction 18 réglable en longueur et munie à son autre extrémité d'un boîtier à rotule 19 dans lequel est montée une rotule solidaire du plancher 4 du véhicule. Between the ball joint 15 and the ball joint 8 at the end of a part of the slide 9 arranged coaxially with the sleeve 16, is fixed a ball joint which is mounted in a ball joint housing 17 integral with one of the ends of a bar of reaction 18 adjustable in length and provided at its other end with a ball joint box 19 in which is mounted a ball joint integral with the floor 4 of the vehicle.

Cette disposition permet de transmettre directement å la barre de commande 11 de la botte de vitesses les mouvements de sélection du levier de vitesses 7 par le coulisseau 9 dont la rotule 15 guidée dans le manchon 16 peut coulisser et pivoter pour épouser les mouvements de sélection. Tous ces organes qui sont solidaires du plancher de la cabine sont reliés par l'axe d'articulation 10 à la barre de commande 11 qui est reliée a la boîte de vitesses 13. Les sollicitations transversales dues aux mouvements de sélection sont contenues par la barre de réaction 18. This arrangement allows the selection movements of the gear lever 7 to be transmitted directly to the control bar 11 of the gear boot by the slider 9 whose ball joint 15 guided in the sleeve 16 can slide and pivot to match the selection movements. All these members which are integral with the cabin floor are connected by the hinge pin 10 to the control bar 11 which is connected to the gearbox 13. The transverse stresses due to the selection movements are contained by the bar 18.
