Abstract
(DE)
Die Erfindung betrifft eine als Baueinheit ausgeführtes wenigstens einkanaliges elektro-pneumatisches zentrales Druckregelmodul (16) für eine elektro-pneumatische Betriebsbremseinrichtung eines Fahrzeugs, mit wenigstens einem in Bezug auf einen Bremsdruck elektrisch regelbaren Druckregelkanal. Die Erfindung sieht vor, dass ein elektronisches Steuergerät (66) des Druckregelmoduls (16) eine elektrische und elektronische Bauteile tragende Platine (94) aufweist, wobei auf oder an der wenigstens einen Platine (94) wenigstens ein Inertialsensor (125, 125a) angeordnet und mit wenigstens einigen der elektrischen und elektronischen Bauteilen auf der Platine (94) elektrisch leitend verbunden ist. Dabei sind Mittel (152, 156, 160) vorgesehen, welche eine geringere Schwingungsbelastung des Inertialsensors (125, 125a) auf der Platine (94) gewährleisten.
(EN)
The invention relates to an at least single-channel electro-pneumatic central pressure control module (16) implemented as a component for an electro-pneumatic service brake of a vehicle, having at least one pressure control channel which is electrically controllable with regard to a brake pressure. The invention provides that an electronic control device (66) of the pressure control module (16) has a board (94) carrying electrical and electronic components, at least one inertial sensor (125, 125a) being arranged on or at the at least one board (94) and being electrically conductively connected to at least several of the electrical and electronic components on the board (94), wherein means (152, 156, 160) are provided which ensure a lower vibration load of the inertial sensor (125, 125a) on the board (94).

L'invention concerne un module de régulation de pression (16) central électropneumatique, au moins monocanal, réalisé sous la forme d'une unité modulaire, pour un dispositif de frein de service électropneumatique d'un véhicule, comprenant au moins un canal de régulation de pression pouvant être régulé électriquement par rapport à une pression de freinage. Selon l'invention, une unité de commande électronique (66) du module de régulation de pression (16) présente une platine (94) comportant des composants électriques et électroniques, au moins un capteur inertiel (125, 125a) étant disposé sur ladite au moins une platine (94) ou au niveau de ladite au moins une platine (94) et étant relié de manière électroconductrice à au moins certains des composants électriques et électroniques sur la platine (94). Le module de régulation de pression présente également des moyens (152, 156, 160) qui garantissent une sollicitation vibratoire plus faible du capteur inertiel (125, 125a) sur la platine (94).
