Drive Assembly, in Particular Hydraulic Assembly of an Electronically Slip-Controllable Vehicle Brake System

A drive assembly has a housing block, on which there is arranged an electrical machine. The latter has a working shaft mounted in a shaft bore of the housing block and the rotational position of which is detected by a sensor device formed by a signal transmitter and a signal receiver comprising evaluation electronics. The shaft bore is closed by a cover, which is arranged between signal transmitter and signal receiver. The cover is formed in one piece with an electronics housing of the signal receiver. A centering device for the signal receiver is formed on the housing block on the electronics housing. The disclosed drive assembly simplifies the construction, functional testing and mounting of the signal receiver and at the same time improves the protection thereof against damaging environmental influences.
