Description
L'invention concerne un frein à régime continu pour véhicules automobiles,The invention relates to a continuous-cycle brake for motor vehicles,
notamment véhicules utilitaires qui sont équipés d'un frein de service avec soupape de frein et de cylindres de frein de roue, et qui sont munis en outre d'un dispositif de protection contre le blocage des freins. Un frein de ce type à régime continu est connu (demande de brevet publiée de la République in particular commercial vehicles which are equipped with a service brake with brake valve and wheel brake cylinders, and which are additionally provided with a device for protection against brake blockage. A brake of this type with continuous operation is known (published patent application of the French Republic
Fédérale d'Allemagne 23 22 446).Federal Republic of Germany 23 22 446).
Dans ce frein connu, on a placé après la soupape de frein de service un commutateur de pression qui permet de brancher la commande de protection antiblocage. Celle-ci est reliée au frein à régime continu. Mais, par suite, ce frein n'est surveillé du point In this known brake, a pressure switch has been placed after the service brake valve which makes it possible to connect the anti-lock protection control. This is connected to the continuous brake. But, as a result, this brake is not monitored

ché. Il en résulte que le comportement en rotation des roues est alors fonction de la somme des forces de freinage du frein de service et du frein à régime continu, et cette somme peut, dans de nombreux ket. As a result, the rotational behavior of the wheels is then a function of the sum of the braking forces of the service brake and the continuous brake, and this sum can, in many cases
états de la route, dépasser l'adhérence possible. states of the road, exceed the possible adhesion.
On a constaté en pratique que les roues de véhicules arrivent dans le domaine d'adhérence critique ou que même une roue peut se bloquer complètement, même si le frein à régime continu est actionné seul. Une telle action exclusive du frein continu est tout à fait courante dans de nombreux véhicules, à l'aide de ce qu'on appelle un "réglage de la force de freinage" avec un commutateur spécial marche-arrêt pour le frein continu. Le conducteur est avisé partiellement, par une indication des instructions de service, que, en cas de route glissante, il ne doit en aucun cas actionner le frein continu. Mais,pour le conducteur, il est très difficile, d'une part, d'apprécier exactement à tout moment l'état de la It has been found in practice that vehicle wheels arrive in the critical grip range or that even a wheel can lock completely, even if the continuous brake is operated alone. Such an exclusive action of the continuous brake is quite common in many vehicles, using what is called a "braking force adjustment" with a special on-off switch for the continuous brake. The driver is partially informed, by an indication of the operating instructions, that in case of slippery road, he must under no circumstances actuate the continuous brake. But, for the driver, it is very difficult, on the one hand, to exactly appreciate at all times the state of the

priées (inversion des commandes ou analogue) à une phase de dérapage déclenchée par la seule action sur le frein continu. A ce sujet, il faut également noter qu'un frein continu a un temps de réponse relativement grand et que même une inversion rapide du commutateur de force de freinage vers sa position de départ peut à peine réduire requested (inversion of the controls or the like) to a skid phase triggered by the only action on the continuous brake. In this regard, it should also be noted that a continuous brake has a relatively long response time and that even a rapid reversal of the brake force switch to its starting position can hardly reduce

Un frein continu 1, 2, 4, 5 est réalisé sous la forme d'un frein à courantsde Foucault et possède un commutateur de force de freinage 1 qui est raccordé par un appareil de commande 2 à un carter 4. Le carter 4 du frein à courants de Foucault est relié par un arbre 5 à un différentiel 7 se trouvant dans un train arrière 6 A DC brake 1, 2, 4, 5 is provided as an eddy current brake and has a brake force switch 1 which is connected by a control unit 2 to a housing 4. The brake casing 4 with eddy current is connected by a shaft 5 to a differential 7 located in a rear axle 6

Au différentiel 7, on a associé un capteur 10 de vitesse de rotation; mais il est également possible de munir chaque roue 8, 9 d'un capteur. Le capteur 10 est raccordé par une ligne à un appareil de commande électronique 11 qui est relié par deux lignes électriques 12 et 13 (une pour le maintien de la pression et une pour l'abaissement de la pression) avec une soupape de commande 14 de protection antiblocage. Les pièces 10, 11, 12, 13 et 14 At the differential 7, there is associated a speed sensor 10; but it is also possible to provide each wheel 8, 9 with a sensor. The sensor 10 is connected by a line to an electronic control device 11 which is connected by two electrical lines 12 and 13 (one for the maintenance of the pressure and one for the lowering of the pressure) with a control valve 14. anti-lock protection. Pieces 10, 11, 12, 13 and 14
- forment un dispositif 10 à 14 de protection antiblocage de frein. - form a device 10 to 14 anti-lock brake protection.
L'appareil de commande 2 du frein continu est relié au dispositif 10 à 14 par les lignes en dérivation 19, 20 ou simplement par la The control unit 2 of the continuous brake is connected to the device 10 to 14 by the branch lines 19, 20 or simply by the
ligne 26 (représentée en pointillé). line 26 (shown in dashed line).
Un frein de service 15, 16, 17 et 18 possède une soupape de frein 15 qui est actionnée en cas de freinage et fait passer l'air comprimé d'un réservoir 16 par la soupape de commande 14 A service brake 15, 16, 17 and 18 has a brake valve 15 which is actuated in the event of braking and passes compressed air from a tank 16 through the control valve 14

La soupape 14 qui reçoit des signaux de commande par l'appareil 11 ne peut cependant pas écarter le risque de blocage, car cette soupape ne peut commander que le risque de blocage déclenché par The valve 14 which receives control signals by the apparatus 11, however, can not avoid the risk of blockage, since this valve can control only the risk of blockage triggered by
l'action du frein de service.the action of the service brake.
C'est seulement par la liaison entre les signaux de commande antiblocage amenés par les lignes 12 et 13 avec l'appareil 2 que la surveillance et la régulation du dispositif de freinage continu sont possibles. On peut imaginer que ces signaux de commande dans l'appareil 2 sont transformés par un circuit a transistor ou à relais de façon que le signal abaisseur de la pression de frein réduise l'effet du dispositif de frein continu et que le signal maintenant la pression ne laisse pas non plus continuer à monter It is only through the connection between the anti-lock control signals supplied by the lines 12 and 13 with the apparatus 2 that the monitoring and regulation of the continuous braking device is possible. It is conceivable that these control signals in the apparatus 2 are transformed by a transistor or relay circuit so that the step-down signal of the brake pressure reduces the effect of the DC brake device and the signal maintains the pressure. do not let either continue to climb

Un schéma simple de transmission des signaux de commande antiblocage au travers des lignes 12 et 13 ou également des signaux de l'accumulateur de régulation par la ligne 26 pour la régulation de l'effet du frein continu est représenté sur la figure 2.

Les signaux de protection antiblocage sortant de l'appareil 11 sont prélevés par les lignes dérivées 19 et 20 sur les lignes 12 et 13 et ils sont amenés au travers de l'élément OU 22 à l'élément ET 23. Ils provoquent en cas de signal de commande du commutateur 1 apparaissant simultanément à l'élément ET 23 - signaux prélevés à la ligne 3 - une attraction du relais 21, de sorte que The anti-lock protection signals leaving the apparatus 11 are taken by the derived lines 19 and 20 on the lines 12 and 13 and are passed through the OR element 22 to the element ET 23.

Une adaptation automatique de l'effet de freinage continu par l'appareil 11 est également possible de façon analogue As a result of a new action on the switch 1, the driver is warned that the continuous braking device is blocked and that he has to switch his de-braking force switch to a lower stage. Automatic adaptation of the continuous braking effect by the apparatus 11 is also possible in a similar way

Mais il faut tenir compte des temps relativement différents de réponse et de déclenchement des différents dispositifs de freinage continu. Dans un frein continu qui est réalisé sous la forme d'un - frein de commande, la commande doit, à cause de l'hydraulique utilisée, être réalisée par une électrovalve supplémentaire. A la place du But it is necessary to take into account the relatively different times of response and tripping of the various braking devices. In a continuous brake which is realized in the form of a - control brake, the control must, because of the hydraulic used, be carried out by an additional solenoid valve. Instead of
