Steering sensor capable of simultaneously measuring steering angle and torque

Abstract

The invention relates to a direction changing sensor capable of simultaneously measuring a direction changing angle and a torque. The direction changing sensor comprises an input shaft (4), an output shaft (8), a torsion bar (5), a first signal round disk (1), a second signal round disk (2) and a third signal round disk (3). One end of the torsion bar (5) is connected with the input shaft (4), and the other end is connected with the output shaft (8); the first signal round disk (1) is connected with the input shaft (4); the second signal round disk (2) and the third signal round disk (3) are connected with the output shaft (8); the three signal round disks are gears made of a ferromagnetic material; the outer peripheries of the three signal round disks are provided with magnetic resistance convertor assemblies (7); and each magnetic resistance convertor assembly (7) comprises three magnetic induction sensors which are respectively arranged at the outer peripheries of the three signal round disks. By utilizing the three signal round disks which are gears made of the ferromagnetic material, the direction changing sensor can simultaneously finish the conversion and measurement of the direction changing torque and the direction changing angle, has simple structure and is convenient for operation.
