Abstract

Ein Druckspeicher für eine Fahrzeugbremsanlage umfasst ein Behälterunterteil, ein Behälteroberteil und mindestens eine Fluidpumpe, wobei die mindestens eine Fluidpumpe zumindest teilweise im Behälterunterteil angeordnet ist, das Behälteroberteil und das Behälterunterteil einen Fluidraum einschließen, in welchen die mindestens eine Fluidpumpe ein Fluid pumpt, und unter Druck stehendes Fluid aus dem Fluidraum ableitbar ist. Aufgrund der Integration der Fluidpumpe in den Druckspeicher weist die Vorrichtung vorteilhafterweise eine geringe Größe und ein geringes Gewicht auf. Die Erfindung betrifft ferner eine Energieeinheit, insbesondere für ein hydraulisch redundantes elektrohydraulisches Bremssystem, mit mindestens einem Elektromotor und mindestens einem Druckspeicher, wobei der Elektromotor die Hydraulikpumpe des Druckspeichers antreibt und Fluid aus dem Fluidraum des Druckspeichers ableitbar ist. Ferner betrifft die Erfindung ein hydraulisch redundantes elektrohydraulisches Fahrzeugbremssystem mit einer solchen Energieeinheit.
