Abstract

The invention relates to an electrohydraulic assembly for an electronically controlled brake system with an accommodating member which includes accommodating bores for electrohydraulic valves, accommodating bores for hydraulic supply devices and an accommodating bore for at least one roller bearing, and with hydraulic channels and pressure fluid ports, as well as with an electric motor comprising a rotor with a shaft that is mounted with the roller bearing in the associated accommodating bore in the accommodating member and used to drive the supply devices, and with an electronic control unit being connected to the electric motor by means of a plug penetrating a through-bore in the accommodating member.The objective is to provide a safe and comfortable operating characteristics even in consideration of extreme environmental influences.This object is achieved because the electrohydraulic assembly includes at least two brake circuits and at least two supply devices per brake circuit, and because the accommodating bores for the supply devices are arranged on top of each other along a first imaginary plane that extends in parallel to the shaft.
