Steering torque detecting device
First Claim
1. A steering torque detecting device, comprising:
- a steering shaft having an input shaft and an output shaft,a torsion bar provided between said input shaft and said output shaft,a torque detecting unit for converting a quantity of torsion produced in said torsion bar into an electric output,an electricity collecting unit comprising a slip ring holder having a flange at one end portion thereof, a plurality of slip rings and brushes which receive said electric output and supply electric power from an outer power source, a plurality of bearings for supporting said input and output shafts on substantially the same axial line, and housing means for supporting said bearings, a terminal block to which said brushes are mounted, a through capacitor interposed between said terminal block and a drawing wire for communicating detection signals outside; and
a potentiometer attached to said flange of said slip ring holder.

Abstract
A steering torque detecting device includes a steering shaft consisting of an input shaft and an output shaft, a torsion bar provided between the input shaft and the output shaft, a torque detecting unit for converting a quantity of torsion produced in the torsion bar into an electric output, an electricity collecting unit including slip rings and brushes which takes the electric output and supplies an electric power from an outer power source, bearings for supporting the input and output shaft on the same axial line, and a housing supporting the bearings, a printed wiring board in a circular plate form which is provided at its one surface with a resistance layer and an output electrode radially spaced apart from the resistance layer, the resistance layer and the output electrode constituting a potentiometer, and a slider having a portion extending in the radial direction of the circular printed wiring board so as to have contacting areas with a small width to the resistance layer and the output electrode.
