Description

La présente invention se rapporte à un dispositif de commande pour le frein de stationnement de véhicules automobiles du type dans lequel une transmission à câble flexible reliée à un levier de commande manuel est agencée pour actionner simultanément les organes de freinage d'une paire de roues de véhicule par l'effet de l'actionnement dudit levier de commande. The present invention relates to a control device for the parking brake of motor vehicles of the type in which a flexible cable transmission connected to a manual control lever is arranged to simultaneously actuate the braking members of a pair of wheels. vehicle by the effect of actuation of said control lever.

Le dispositif de commande selon l'invention est caractérisé par le fait que la transmission comprend un c!- ble flexible principal qui relie le levier de commande à l'organe de freinage de l'une des deux roues du véhicule et embrasse une poulie de renvoi portée par un organe support qui peut se rapprocher et s'éloigner de ladite roue du véhicule, et un cSble flexible secondaire dont une extrémité est reliée à l'organe de freinage de l'autre roue du véhicule et dont l'extrémité opposée est ancrée audit organe support de la poulie de renvoi du câble principal. The control device according to the invention is characterized in that the transmission comprises a main flexible cable which connects the control lever to the braking member of one of the two wheels of the vehicle and embraces a pulley of return carried by a support member which can approach and move away from said vehicle wheel, and a secondary flexible cable, one end of which is connected to the braking member of the other vehicle wheel and the opposite end of which is anchored to said support member of the main cable return pulley.

Grâce à cette caractéristique, on obtient d'une façon simple et économique une répartition uniforme de l'effort transmis du levier de commande manuel aux organes de freinage des deux roues. Thanks to this characteristic, a uniform and economical distribution of the force transmitted from the manual control lever to the braking members of the two wheels is obtained in a simple and economical manner.

L'organe support est de préférence constitué par un levier oscillant dont une extrémité est articulée pour tourner autour d'un axe perpendiculaire à la droite joignant les deux roues et qui porte à son autre extrémité la poulie de renvoi du câble principal et un bras latéral servant à l'ancrage du cable secondaire. The support member is preferably constituted by an oscillating lever, one end of which is articulated to rotate about an axis perpendicular to the right joining the two wheels and which carries at its other end the pulley returning the main cable and a lateral arm used to anchor the secondary cable.

D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description qui va suivre d'un exemple de réalisation et en se référant aux'dessins annexés sur lesquels,
la figure 1 est une vue schématique en plan d'un dispositif de commande selon l'invention
la figure 2 représente à plus grande échelle un détail de la figure 1.
Other characteristics and advantages of the invention will be better understood on reading the description which follows of an exemplary embodiment and with reference to the appended drawings in which,
Figure 1 is a schematic plan view of a control device according to the invention
FIG. 2 represents a detail of FIG. 1 on a larger scale.

Comme on peut le voir en se reportant initiale ment à la figure 1, on a indiqué schématiquement en A le plancher d'un véhicule automobile muni de deux roues arriè- re R1, R2. Les deux roues R1, R2 sont équipées de freins
F1, F2 respectivement, de type classique, munis, d'une fa çon connue en soi, de leviers d'actionnement L1 et L2 reliés à un dispositif de commande 10 pour le freinage de stationnement des roues R1, R2.
As can be seen by referring initially to FIG. 1, the floor of a motor vehicle provided with two rear wheels R1, R2 has been shown diagrammatically at A. The two wheels R1, R2 are equipped with brakes
F1, F2 respectively, of the conventional type, provided, in a manner known per se, with actuating levers L1 and L2 connected to a control device 10 for parking braking of the wheels R1, R2.

Le dispositif de commande 10 comprend un levier de commande manuel 12 de type connu en soi, monté à l'intérieur de l'habitacle du véhicule et muni d'un dispositif d'arrêt à encliquetage qui peut être libéré manuellement de façon classique. Au levier de commande 12 est reliée une extrémité 14 d'un cible principal flexible 16 qui traverse à coulissement une paire de manchons passe-cb1e 18, 20, espacés l'un de l'autre, embrasse une poulie de renvoi 22, passe dans une gaine 34 interposée entre deux organes de réaction espacés 26 et 28 et s'ancre au levier d'actionnement L1 du frein F1 de la roue R1. Un ressort de rappel
M1 est interposé entre le levier L1 et l'organe de reac- tion 28.
The control device 10 comprises a manual control lever 12 of a type known per se, mounted inside the passenger compartment of the vehicle and provided with a latching stop device which can be released manually in a conventional manner. To the control lever 12 is connected one end 14 of a flexible main target 16 which slides to slide a pair of cb1e sleeves 18, 20, spaced from each other, embraces a deflection pulley 22, passes in a sheath 34 interposed between two spaced apart reaction members 26 and 28 and is anchored to the actuation lever L1 of the brake F1 of the wheel R1. A return spring
M1 is interposed between the lever L1 and the reaction member 28.

I1 convient de remarquer que, dans le cas où les roues R1, R2 sont portées par des bras respectifs qui oscillent autour d'un axe transversal (non représentés sur les dessins), le manchon passe-cable 20 est disposé sensiblement sur cet axe transversal. I1 should be noted that, in the case where the wheels R1, R2 are carried by respective arms which oscillate around a transverse axis (not shown in the drawings), the cable sleeve 20 is disposed substantially on this transverse axis .

La poulie 22 est montée rotative à une extrémité d'un levier oscillant 30 dont l'extrémité opposée est articulée à la structure porteuse du véhicule par un pivot 32 dirigé verticalement, c'est-à-dire perpendiculairement au plancher A du véhicule. Comme on le voit clairement sur la figure 1, le levier oscillant 30 s'étend sensiblement pa rallèlement à l'axe longitudinal X du véhicule, de wme que le segment 16a du câble principal 16 compris entre le manchon passe-c ble 20 et la poulie 22. Le levier oscillant 30 est disposé à proximité de l'axe Y des deux roues
R1 et R2 et il est déporté par rapport à l'axe longitudi nal X du véhicule, vers la roue R2.Toutefois, la position du levier 30 pourrait être différente de celle représentée, selon la position du réservoir ou des autres organes du véhicule situés dans la partie arrière du plancher .
The pulley 22 is rotatably mounted at one end of an oscillating lever 30, the opposite end of which is articulated to the carrying structure of the vehicle by a pivot 32 directed vertically, that is to say perpendicular to the floor A of the vehicle. As can be clearly seen in FIG. 1, the oscillating lever 30 extends substantially pa parallel to the longitudinal axis X of the vehicle, so that the segment 16a of the main cable 16 comprised between the cable sleeve 20 and the pulley 22. The oscillating lever 30 is disposed near the Y axis of the two wheels
R1 and R2 and it is offset relative to the longitudinal axis X of the vehicle, towards the wheel R2.However, the position of the lever 30 could be different from that shown, depending on the position of the tank or other vehicle components located in the rear part of the floor.

Ainsi qu'on l'a représenté plus clairement sur la figure 2, l'extrémité du levier oscillant 30 qui porte la poulie 22 est munie d'une patte ou d'un bras 34 qui fait saillie latéralement vers la roue R2. A l'extrémité libre du bras 34 est ancrée une extrémité d'un câble flexible secondaire 36 qui passe dans une gaine 38 interposée entre deux organes de réaction espacés 40 et 42 et dont l'extr6- mité opposée est ancrée au levier d'actionnement L2 du frein F2 de la roue R2. Un ressort de rappel M2 est disposé entre le levier L2 et l'organe de réaction 42. As shown more clearly in FIG. 2, the end of the oscillating lever 30 which carries the pulley 22 is provided with a lug or an arm 34 which projects laterally towards the wheel R2. At the free end of the arm 34 is anchored one end of a secondary flexible cable 36 which passes through a sheath 38 interposed between two spaced apart reaction members 40 and 42 and the opposite end of which is anchored to the actuation lever L2 of brake F2 of wheel R2. A return spring M2 is arranged between the lever L2 and the reaction member 42.

En revenant encore une fois à la figure 1, on peut observer que le brin 16b du câble principal 16 aussi bien que le brin 36a du câble secondaire 36 qui partent du levier oscillant 30 pour s'ancrer à leurs leviers d'actionnement respectifs L1 et L2 sont dirigés approximativement perpendiculairement à ce levier oscillant 30 ou à peu près parallèlement à l'axe Y des deux roues R1 et R2. Returning once again to FIG. 1, it can be observed that the strand 16b of the main cable 16 as well as the strand 36a of the secondary cable 36 which start from the oscillating lever 30 to anchor to their respective actuation levers L1 and L2 are directed approximately perpendicular to this oscillating lever 30 or approximately parallel to the axis Y of the two wheels R1 and R2.

En utilisation, la traction exercée sur le cible principal 16 par l'effet du relevage manuel du levier de commande 12 provoque à la fois l'avancement du levier d'actionnement L1, avec actionnement ou serrage consécutif du frein F1 de la roue R1 et une rotation simultanée du levier oscillant 30 autour de l'axe 32, dirigée vers la roue R1, avec traction consécutive du cible secondaire ancré au bras 34, en provoquant l'avancement du levier L2 et, par conséquent, le serrage simultané du frein F2 de la roue
R2. On obtient de cette façon une répartition correcte en parties égales de l'effort appliqué à la transmission 10 par l'intermédiaire du levier de commande 12.
In use, the traction exerted on the main target 16 by the effect of manual lifting of the control lever 12 causes both the advancement of the actuation lever L1, with subsequent actuation or application of the brake F1 of the wheel R1 and a simultaneous rotation of the oscillating lever 30 around the axis 32, directed towards the wheel R1, with consecutive traction of the secondary target anchored to the arm 34, causing the advancement of the lever L2 and, consequently, the simultaneous application of the brake F2 of the wheel
R2. In this way a correct distribution is obtained in equal parts of the force applied to the transmission 10 by means of the control lever 12.

Lorsque le levier de commande 12 est ramené manuellement à sa position abaissée ou de repos, les leviers d'actionnement L1 et L2 reviennent à la position de repos sous l'action de leurs ressorts respectifs M1 et M2 tandis que le levier oscillant 30 se replace dans la position centrale de la figure 1. When the control lever 12 is returned manually to its lowered or rest position, the actuation levers L1 and L2 return to the rest position under the action of their respective springs M1 and M2 while the oscillating lever 30 is replaced in the central position of figure 1.

Bien entendu, diverses modifications pourront être apportées par l'homme de l'art au dispositif qui vient d'être décrit uniquement à titre d'exemple non limitatif sans pour cela sortir du cadre de l'invention.  Of course, various modifications may be made by those skilled in the art to the device which has just been described solely by way of nonlimiting example without thereby departing from the scope of the invention.
