Integrally-containing type torque sensor motor

Abstract

The invention provides an integrally-containing type torque sensor motor. A motor shell and a motor shaft are provided with a hollow containing cavity which is composed of annular bulges in a coaxial direction; a fixed sliding guide ring is contained and arranged in the hollow containing cavity and the fixed sliding guide ring is dynamically matched with a floating ratchet induction coil subassembly which is equipped with magnetic steel; the floating ratchet induction coil subassembly comprises a ratchet induction coil and ratchets of a flywheel are matched with gear grooves which are annularly distributed in the ratchet induction coil; the motor shaft is provided with a Hall element and the magnetic steel of the floating ratchet induction coil subassembly is matched with the Hall elementin a magnetic induction manner, so that an electric signal is output to control stress-applied rotation of vehicles. According to the invention, all parts of a Hall sensor are skillfully arranged on the motor shell so that the space occupation problem caused by function settings is solved; the integrally-containing type torque sensor motor has the advantages of high standardization degree, wide application range, obvious magnetic induction effects, easiness of intensive production, low carbon, environmental friendliness, and convenience for installation and maintenance.
