Title:
【発明の名称】パワーステアリングの入力トルク検出装置
Document Type and Number:
Japanese Patent JP3375972
Kind Code:
B2
Abstract:
There is provided an input torque detecting device, in power steering, which converts a relative rotation of an input shaft and an output shaft into a movement in a direction of a shaft so as to detect torque. The input shaft 1 and the output shaft 3 are connected via a torsion bar 2 and also a sleeve 7 is installed at a common outer circumference of the input shaft 1 and the output shaft 3. The sleeve is connected to the input shaft 1 through helical splines 8a and 8b which extend in a direction diagonal to a shaft line and connected to the output shaft 3 through straight splines 9a and 9b which extend in a direction of a shaft line, respectively. Torsion of the torsion bar 2 based on input torque is detected as an amount of slide of the sleeve in a direction of a shaft line to be determined by the helical splines 8a and 8b. By applying splines to a section of engaging the input shaft 1 and the output shaft 3 with the sleeve 7, manufacturing costs can be curtailed and also durability of the engaging section can be improved.
