Abstract
Official abstract text for this publication.
A steering system includes a pinion shaft with pinion teeth formed thereon, a rack shaft with rack teeth formed thereon and meshing with the pinion teeth, and a pair of stoppers that regulates movement of the rack shaft at right and left stroke end positions of the rack shaft. The rack teeth are formed such that the rack teeth on a first end side of the rack shaft and the rack teeth on a second end side of the rack shaft are asymmetric with respect to a reference position, the reference position being an area of the rack teeth, in which the rack teeth mesh with the pinion teeth in a steering neutral state. In regard to a stroke position of the rack shaft, the stroke end positions are each offset from a peak generation stroke position where a dedendum stress of the rack teeth based on meshing transmission via the pinion teeth reaches a peak.
First claim
Opening claim text (preview).
What is claimed is: 1 . A steering system comprising: a pinion shaft with pinion teeth formed thereon; a rack shaft with rack teeth formed thereon and meshing with the pinion teeth; and a pair of stoppers that regulates movement of the rack shaft at right and left stroke end positions of the rack shaft, wherein the rack teeth are formed such that the rack teeth on a first end side of the rack shaft and the rack teeth on a second end side of the rack shaft are asymmetric with respect to a reference position, the reference position being an area of the rack teeth, in which the rack teeth mesh with the pinion teeth in a steering neutral state, and in regard to a stroke position of the rack shaft, the stroke end positions are each offset from a peak generation stroke position where a dedendum stress of the rack teeth based on meshing transmission via the pinion teeth reaches a peak. 2 . A rack shaft used for the steering system according to claim 1 .
