Device for an electrohydraulic power supply for a power steering system in a motor vehicle

摘要

Electrohydraulic pressure supply for an auxiliary power source within a motor vehicle has an a pump (1) driven by an electric motor (3), with the pump (2) contained within an oil filled container (3), with the oil circulating through an outlet (8) and a return (9). The axles (4, 5) of both pump and electric motor are concentric and share a common bearing (7), with separate bearings (7a) and (7b) respectively. The bearing is fixed in an adapter which holds the container (1) to the electric motor (3), and is fixed to the electric motor side. Fixed to the side of the adapter, so that they are in thermal contact, are motor control-electronics.
