Title: EXTERNAL DAMPING OF POWER STEERING FOR A VEHICLE
Abstract:
A steering member has a rack portion and a screw portion. The steering member is in a steering housing and operatively connected to a tie rod. A pinion is operatively connected between the rack portion and a steering wheel. A ball nut is operatively connected to the screw portion. A power source is operatively connected to the ball nut. The power source drives the ball nut to effect linear movement of the steering member upon rotation of the steering wheel. A damper has a first connection to the tie rod and a second connection to a ground surface. The ground surface is fixed relative to the steering member. The damper is external to the ball nut.
