摘要：A steering system (10) comprises a hand wheel (12) positioned for manipulationby a driver, a steering shaft (16) extending from the hand wheel (12), and a magneticcolumn lock (50). The steering shaft (16) is supported by a steering column housing (14)so that it can rotate on its own axis. The magnetic column lock (50) includes a rotor (28)
attached to steering shaft (16), a stator attached to column housing (14), and
magnetorheological fluid (33) filling a space between the rotor (28) and stator (29). Inanother aspect of the steering system (10), the steering shaft (16) extends from the handwheel (12) through a hand wheel actuator (20) having a position sensor (22) and a motor(24) for providing driver feedback. A steering column (34) extends from a lower portion(19) of said steering shaft (16) to a rack (34), and includes a pinion (32) at its lower end(19) for engagement with the rack (34), so that the rack (34) translates left and rightwhen the pinion (32) is rotated in corresponding directions. The rack (34) is connected tothe front road wheels (28) and causes the front road wheels (28) to steer when it istranslated. An electronic controller (30) receives signals indicative of an angular positionof the hand wheel (12) from the position sensor (22), and a road wheel actuator (40)connected to the steering rack (34) receives signals from the electronic controller (30)and repositions the steering rack (34) in response to the signals from said electroniccontroller (30). A magnetic clutch (26) having MR fluid (33) is provided for selectivelyengaging said steering shaft (16) to said steering column (14).
