Abstract
Official abstract text for this publication.
A design assisting apparatus of a steering device arranges a coordinate of a handle position reference point, a coordinate of a first universal joint reference point, a coordinate of a second universal joint reference point, and a coordinate of a steering gear reference point in a three-dimensional space, calculates a reference axis passing through the second universal joint reference point from the first universal joint reference point, calculates a phase angle which is an angle between a straight line from the handle position reference point to the first joint reference point when viewed along the reference axis and a straight line from the second joint reference point to the steering gear reference point when viewed along the reference axis, and determines success or failure of a condition in which the allowable range of the phase angle allowable error is included in the allowable range of the allowable torque variation rate.
First claim
Opening claim text (preview).
The invention claimed is: 1. A design assisting apparatus of a steering device including a steering mechanism with a column yoke, a slide tube yoke, a slide shaft yoke, and a pinion-side yoke, the design assisting apparatus comprising: a storage unit that stores a coordinate of a handle position reference point of a handle, a coordinate of a first universal joint reference point connecting the column yoke and the slide tube yoke, a coordinate of a second universal joint reference…
