Abstract
Official abstract text for this publication.
A steering system includes a rack shaft, a rack housing, a rack end, and an impact absorbing member that is provided between a restriction face formed within the rack housing and an end face of the rack end, and that absorbs an impact generated when the restriction face and the end face come into contact with each other. The impact absorbing member includes an elastic portion, and a restriction portion having an elastic modulus higher than that of the elastic portion and having a length in the axial direction, which is shorter than that of the elastic portion. A compression allowance, which is a difference in length in the axial direction between the elastic portion and the restriction portion, is brought to zero when the restriction face and the end face come into contact with each other via the impact absorbing member due to a steering input.
First claim
Opening claim text (preview).
What is claimed is: 1. A steering system comprising: a steered shaft that is able to reciprocate in an axial direction of the steered shaft; a housing that accommodates the steered shaft; a joint that is fitted to a shaft end portion of the steered shaft so as to connect the steered shaft to a steered wheel such that the steered wheel is allowed to be steered; and an impact absorbing member that is provided between a restriction face formed within the housing and an end face…
