Electrical power steering for motor vehicle has hydraulic pressure biasing device, coupling for connecting drive shaft to worm and pivotable bearing in coupling region

摘要

The electrical power steering device has a worm drive that interacts with a drive shaft (9) of an electric motor, whereby a worm (3) is radially loaded by a biasing device. The biasing device is a hydraulic pressure device (12) and the drive shaft can be connected to the worm via a coupling (8), whereby the bearing for the worm is a pivotable bearing (5) in this region.
