Abstract: A rack assembly for a vehicle steering system includes a first rack component extending longitudinally from a first outer end to a first inner end, the first rack component having a first shoulder extending radially outwardly from a neck region to a head region. The rack assembly also includes a second rack component extending longitudinally from a second outer end to a second inner end, the second rack component having a second shoulder extending radially outwardly from a neck region to a head region. The rack assembly further includes a coupling assembly having an inner surface defining a hollow region that the head region of the first rack component and the head region of the second rack component are each disposed within, the inner surface having a first radial protrusion in abutment with the first shoulder and a second radial protrusion in abutment with the second shoulder.

Abstract: 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.

Abstract: A rack bar blank for a steering system is provided. The rack bar blank includes a first region having a circular cross-section. The rack bar blank also includes a second region having a flattened surface along a length thereof, the flattened surface present prior to formation of teeth.

Abstract: The present invention provides an apparatus and method of utilization thereof of a clutch for placement between a robot or the like and an attached end of arm tooling device. A preferred embodiment of the inventive clutch provides compliance in six axes with adjustable setting and detection means to signal the robot or like to cease operation upon deformation of the clutch element.
