Abstract

Device according to Claim 1 of the Application 85 06210, characterised in that it further comprises a spring means 104 bearing against a casing 36 of the device and stressing each of the two thrust rods 28, 28' so as to reduce any play between the casing 36 and the thrust rods 28, 28'.

Description

DISPOSITIF DE COMMANDE POUR MAITRE-CYLINDRE DOUBLE
La présente invention concerne des développements apportés au dispositif de commande faisant l'objet de la demande de brevet principale No 85 06210 déposée le 24
Avril 1985.CONTROL DEVICE FOR DOUBLE MASTER CYLINDER
The present invention relates to developments in the control device which is the subject of main patent application No 85 06210 filed on 24
April 1985.

La demande de brevet principale décrit un dispositif de commande pour maitre-cylindre double du type comprenant deux maître-cylindres placés parallèlement côte à côte, le dipositif étant susceptible d'être placé entre une pédale d'actionnement et les pistons des maître-cylindres. Le dispositif comporte une tige de commande susceptible d'être reliée à la pédale et deux tiges de poussée susceptibles d'agir chacune sur un piston respectif. Les tiges de poussée sont guidées en coulissement paraLlèLement aux axes des maître-cylindres et coopèrent avec la tige de commande au travers d'un système de leviers. The main patent application describes a control device for a double master cylinder of the type comprising two master cylinders placed parallel side by side, the device being capable of being placed between an actuating pedal and the pistons of the master cylinders. The device comprises a control rod capable of being connected to the pedal and two push rods each capable of acting on a respective piston. The push rods are guided in sliding parallel to the axes of the master cylinders and cooperate with the control rod through a system of levers.

Malgré ses avantages, le dispositif précédent présente de légers inconvénients en ce qu'il ne permet pas d'éviter un certain jeu entre les tiges de poussée et le boitier. Despite its advantages, the previous device has slight drawbacks in that it does not prevent a certain play between the push rods and the housing.

La présente invention a donc pour objet de proposer un dispositif de commande évitant ces inconvénients et dans lequel le jeu précité est considérablement réduit, voire éliminé. The present invention therefore aims to provide a control device avoiding these drawbacks and in which the aforementioned clearance is considerably reduced, or even eliminated.

Pour ce faire l'invention propose un dispositif de commande pour maitre-cylindre double caractérisé en ce qu'il comprend en outre un moyen de ressort prenant appui contre un boîtier du dispositif et sollicitant chacune des deux tiges de poussée afin de réduire un jeu éventuel entre le boîtier et les tiges de poussée. To do this, the invention provides a control device for a double master cylinder, characterized in that it further comprises a spring means bearing against a housing of the device and urging each of the two push rods in order to reduce possible play. between the housing and the push rods.

D'autres caractéristiques et avantages de La présente invention ressortiront de La description suivante d'un mode de réalisation donné à titre illustratif mais nullement limitatif, faite en relation avec les dessins annexés, dans lesquels la figure unique est une vue en coupe longitudinale d'un dispositif de commande selon l'invention. Other characteristics and advantages of the present invention will emerge from the following description of an embodiment given by way of illustration but in no way limiting, made in relation to the appended drawings, in which the single figure is a view in longitudinal section of a control device according to the invention.

Les éléments identiques ou analogues dans la présente demande et dans la demande principale portent les mêmes chiffres de référence. Identical or analogous elements in this application and in the main application bear the same reference numbers.

Comme représenté sur la figure, le dispositif de commande est simplifié par rapport à celui de la demande principale en ce que la tige de commande 44 est montée directement dans une ouverture taraudée 100 dans le couvercle 34 du boîtier 36. Les zones en forme de came 76 et 78 des Leviers 52 et 54 prennent appui directement sur une surface interieure 102 du couvercle 34. Les extrémités libres 64 et 66 de chaque levier 52, 54 comportent chacune une surface de came 68 et 70 placée en appui contre une surface extérieure des axes 62 et 60 solidaires des tiges de poussée respectives 28 et 28'. As shown in the figure, the control device is simplified compared to that of the main request in that the control rod 44 is mounted directly in a tapped opening 100 in the cover 34 of the housing 36. The cam-shaped zones 76 and 78 of the Levers 52 and 54 bear directly on an interior surface 102 of the cover 34. The free ends 64 and 66 of each lever 52, 54 each have a cam surface 68 and 70 placed in abutment against an external surface of the axes 62 and 60 integral with the respective push rods 28 and 28 '.

Afin de réduire le jeu entre les tiges de poussée 28, 28' et le boîtier 36, le dispositif de commande comprend un ou deux ressorts lame 104, sensiblement en forme de V, qui est disposé à L'intérieur du boîtier 36. In order to reduce the clearance between the push rods 28, 28 ′ and the housing 36, the control device comprises one or two leaf springs 104, substantially V-shaped, which is arranged inside the housing 36.

Le sommet 106 du ressort lame 104 est en appui contre une surface intérieure 108 du boîtier 36 et l'extrémité de chaque bras 110, 112 prend appui contre un axe respectif 60, 62 ou, comme représenté , sur une portion adjacente du levier correspondant. Le ressort lame 104 sollicite ainsi les deux tiges de poussée 28, 28' vers la droite (en regardant les dessins), rattrapant ainsi le jeu éventuel entre les tiges et le boîtier 36.  The top 106 of the leaf spring 104 bears against an interior surface 108 of the housing 36 and the end of each arm 110, 112 bears against a respective axis 60, 62 or, as shown, on an adjacent portion of the corresponding lever. The leaf spring 104 thus biases the two push rods 28, 28 ′ to the right (looking at the drawings), thus making up for any play between the rods and the housing 36.
