Abstract: A steering gear assembly includes a pinion defining a pinion axis and a rack defining a rack axis. A bearing assembly includes a roller bearing biased against the rack to generate a normal force pressing the rack into engagement with the pinion. The bearing assembly engages an outer surface of the rack at two points circumferentially spanning a large degree to provide improved support. The roller bearing is preferably a plurality of ball bearings engaging an outer race. A deformable member may be utilized that is positioned between the outer race and the rack housing. The deformable member may comprise a series of O-rings which providing a force biasing the outer race towards the pinion.

Abstract: A composite tubular housing for an automotive steering system, preferably an electronic power assist steering system, is formed of seamless metal tube section welded into an integral component. The housing includes a rack section and a pinion section having an opening that is welded to the rack section. A yoke section is formed of a tube having an end that is welded to the rack section opposite the pinion section. The pinion section may contain a drive pinion coupled to a steering wheel of the vehicle. The housing may also include sections for an assist pinion coupled to an electric motor, and a yoke which are attached to the rack section apart from the drive pinion.

Abstract: An assisted steering system is provided. In preferred embodiments, the system has driver and assist pinions that are out of phase with each other. As a tooth of the driver pinion is fully engaged with a rack tooth, a tooth of the assist pinion is only partially engaged with a tooth of the rack. Preferably, the driver and assist pinions have differing rack speeds and numbers of teeth.
