La présente invention concerne un système hydraulique de freinage à régulation du glissement destiné à des véhicules automobiles, comprenant un maltre-cylindre de freinage et un amplificateur précédant le maîtrecylindre de freinage, une source d'énergie auxi5 liaire constituée d'une pompe de liquide de pression comprenant un The present invention relates to a hydraulic brake system with slip regulation intended for motor vehicles, comprising a brake master cylinder and an amplifier preceding the brake master cylinder, an auxiliary energy source consisting of a liquid pump. pressure including a
système commandé d'entraînement électromoteur ainsi qu'un accumulateur hydraulique, un réservoir de compensation relié à l'entrée de la pompe de liquide de pression, au moins un bloc de valves comprenant des électrovannes pour appliquer du liquide de pression hydraulique 10 à des organes de freinage, une unité électronique de régulation et un dispositif limitant la course de la pédale de frein en cas de régulation du glissement de freinage. controlled electromotive drive system as well as a hydraulic accumulator, a compensation tank connected to the inlet of the pressure liquid pump, at least one block of valves comprising solenoid valves for applying hydraulic pressure liquid 10 to organs brake, an electronic control unit and a device limiting the stroke of the brake pedal in the event of brake slip regulation.
En raison de leur conception complexe, tous les systèmes hydrauliques de freinage à régulation de glissement connus occupent un 15 espace très important, ce qui est considéré comme un inconvénient dans la mesure o la place disponible dans le compartiment-moteur Owing to their complex design, all known hydraulic brake systems with slip regulation occupy a very large space, which is considered to be a drawback insofar as the space available in the engine compartment
d'un véhicule automobile est, en toute hypothèse, limitée. of a motor vehicle is, in any event, limited.
La présente invention a donc pour but de disposer les organes déjà prévus dans un système hydraulique de freinage à régulation 20 du glissement connu, de manière à réaliser un gain de place considérable. The object of the present invention is therefore to arrange the members already provided in a hydraulic braking system with known slip regulation 20, so as to save considerable space.
Conformément à la présente invention, cet but est atteint en In accordance with the present invention, this object is achieved by
ce que l'amplificateur, le maître-cylindre, l'unité électronique de régulation, le réservoir de compensation et le bloc de valves sont 25 conçus sous la forme de composants modulaires. that the amplifier, the master cylinder, the electronic control unit, the compensation tank and the valve block are designed as modular components.
Conformément à la présente invention, on obtient un système In accordance with the present invention, a system is obtained
hydraulique qui permet, en raison de son très faible encombrement, d'utiliser la place disponible pour monter, dans le véhicule automobile, un amplificateur d'effort de freinage à dépression. hydraulic which allows, because of its very small footprint, to use the space available to mount, in the motor vehicle, a vacuum brake force amplifier.
Conformément à la présente invention, un perfectionnement In accordance with the present invention, an improvement
approprié du système de freinage prévoit l'implantation de deux blocs de valves qui sont disposés symétriquement dans la zone de l'amplificateur. Il en résulte une plus grande standardisation dans la mesure o les versions gauche et droite sont identiques. En outre, cela per35 met d'utiliser un maître-cylindre de freinage étroit et donc de ré- appropriate braking system provides for the installation of two valve blocks which are arranged symmetrically in the area of the amplifier. This results in greater standardization since the left and right versions are identical. In addition, this makes it necessary to use a narrow brake master cylinder and therefore to re-

duire considérablement la hauteur totale. considerably reduce the total height.
Un autre mode de réalisation avantageux du système de freinage conforme à l'invention réside en ce que la source d'énergie auxiliaire, constituée par la pompe de liquide de pression, le système d'entraînement électromoteur et l'accumulateur hydraulique, est séparée de l'amplificateur. Un mode de réalisation de ce type permet avantageusement de réduire dans une grande mesure les bruits et/ou les vibrations qui se produisent lorsque l'ensemble est en fonctionnement, étant donné que la pompe de liquide de pression associée à 10 l'accumulateur et le moteur entraînant la pompe peuvent être montés en un endroit quelconque du véhicule automobile. Another advantageous embodiment of the braking system according to the invention resides in that the auxiliary energy source, constituted by the pressure liquid pump, the electromotive drive system and the hydraulic accumulator, is separated from the amplifier. An embodiment of this type advantageously makes it possible to reduce to a large extent the noises and / or vibrations which occur when the assembly is in operation, since the pressure liquid pump associated with the accumulator and the motor driving the pump can be mounted anywhere on the motor vehicle.
La longueur totale du système hydraulique de freinage conforme à la présente invention peut également être réduite en ce que le dispositif de limitation de la course de la pédale de frein est 15 constitué par des valves de blocage disposées symétriquement par rapport à l'amplificateur. The total length of the hydraulic braking system according to the present invention can also be reduced in that the device for limiting the stroke of the brake pedal consists of blocking valves arranged symmetrically with respect to the amplifier.
