Abstract: A redundant gear assembly for a vehicle steering column includes a gear operatively coupled to a steering column component. Also included is a first and second set of gear teeth on the gear. Yet further included is a first motor driving a first gear input component, the first gear input component in meshed engagement with the first set of gear teeth to provide a first steering assist torque that is representative of a desired steering assist torque in a primary operating mode of the redundant gear assembly. Also included is a second motor driving a second gear input component, the second gear input component in meshed engagement with the second set of gear teeth to provide a second steering assist torque in a redundant operating mode of the redundant gear assembly, the second motor not driving the second gear input component in the primary operating mode.

Abstract: A gear includes a gear body and a first gear tooth. The gear body extends radially between an outer portion and an inner portion. The first gear tooth has a first tooth portion, a second tooth portion, and a first slot. The first tooth portion extends radially from the outer portion towards a first land. The second tooth portion is circumferentially spaced apart from the first tooth portion and extends radially from the outer portion towards a second land. The first slot is defined between the first tooth portion and the second tooth portion and extends from at least one of the first land and the second land towards a first slot root.

Abstract: A gear assembly includes a first gear and a second gear. The first gear rotates about a first axis, and includes a first plurality of teeth and a first surface extending circumferentially and carried by the first plurality of teeth. The first surface is electrically conductive. The second gear rotates about a second axis and is operably connected to the first gear. The second gear includes an electrically conductive element, a second plurality of teeth, and a second surface extending circumferentially and carried by the second plurality of teeth. The second surface is electrically nonconductive. The electrically conductive element includes a plurality of feelers with each feeler projecting radially outward and into a respective tooth of the second plurality of teeth.

Abstract: A method of making a worm gear. The method includes forming a gear blank having a plurality of individual lugs formed about an outer circumferential edge of said blank to facilitate a uniform flow of a material around said plurality of individual lugs. The method also includes molding said material around said plurality of individual lugs to form a ring.

Abstract: A method of making a worm gear is provided. The method comprises forming a gear hub from a powdered metal material. Thereafter an outer surface of the gear hub is sealed.

Abstract: A vehicle steering column assembly includes a first shaft having a first shaft cavity extending from an end of the first shaft. Also included is a second shaft operatively coupled to the first shaft, the second shaft having a second shaft cavity disposed therein. Further included is a torsion bar disposed within the first shaft cavity and the second shaft cavity. Yet further included is a stop tooth extending from the first shaft. Also included is a worm gear defining a slot with a slot wall, a first portion of the slot wall configured to engage a first side of the stop tooth to define a first radial boundary of the worm gear, a second portion of the slot wall configured to engage a second side of the stop tooth to define a second radial boundary of the worm gear.

Abstract: A power-assisted steering system includes an intermediate housing, a motor cone housing coupled to the intermediate housing, and a control shaft arranged along a control shaft axis for rotation about the control shaft axis. The system further includes an assist drive shaft arranged in a plane that is substantially transverse to the control shaft axis, the assist drive shaft being supported relative to the vehicle structure by a first bearing assembly and a second bearing assembly and defining a drive shaft axis, a worm disposed about the assist drive shaft, and a worm gear coupled to the control shaft. The worm gear and control shaft are configured for rotation about the control shaft axis.
