A rack electric power steering system includes a rack having a single set of teeth with a constant tooth pitch. The system also includes a first pinion operatively coupled to a steering shaft and in meshed engagement with the single set of teeth of the rack. The system further includes a second pinion operatively coupled to an electric motor and in meshed engagement with the single set of teeth of the rack.

Pinion electric power steering system

A rack and pinion steering system includes a housing, a rack, a pinion gear, and a radially preloaded rack bearing. The rack is supported by the housing, and the pinion gear is meshed to the rack. The radially preloaded rack bearing is supported and preloaded to the housing and is preloaded to the rack.

Radially preloaded rack bearing

A rack bar blank for a steering system includes a first region having a first diameter. The rack bar blank also includes a second region having a second diameter that is greater than the first diameter prior to formation of teeth on the second region and a ball screw thread on the first region.

Steering system rack with stepped portion

A steering system is provided. The steering system may include a drive pulley and a ball nut assembly. The drive pulley may be operatively connected to a drive shaft. The ball nut assembly may be driven by the drive pulley via a belt disposed about the drive pulley and the ball nut assembly. The ball nut assembly may include a ball nut and a driven pulley. The ball nut may have an inner surface disposed about a ball screw that defines and extends along a first axis and an outer surface disposed opposite the inner surface. The ball nut may define a first groove that extends from the outer surface towards the inner surface. The driven pulley may be disposed about the ball nut and have a retaining member that includes a finger for extending into the first groove to engage the ball nut and driven pulley without separate fasteners.
