Abstract

The invention relates to a steering sensor assembly which comprises a gear ring assembly, a conduction assembly, a Hall chip set and circuit boards. The gear ring assembly and the conduction assemblyare connected in a matched mode; the circuit boards comprise the angle circuit board and the torque circuit board; the Hall chip set comprises a first Hall chip, a second Hall chip, a third Hall chipand a fourth Hall chip; a large gear is arranged on the side portion of the gear ring assembly; a first pinion and a second pinion are arranged on the two sides of the large gear; a first magnet is arranged on the position, corresponding to the first Hall chip, on a rear fixing plate; and a second magnet is arranged on the position, corresponding to the second Hall chip, on the rear fixing plate.The steering sensor assembly has the characteristics of being firm in structure, small in size, small in mass, long in life, convenient to mount, small in power consumption, resistant to vibration, oil stain, corrosion, dust and salt mist, and the like.

Description

technical field [0001] The invention relates to the technical field of an electric power steering gear of an automobile and an electronic stability system of an automobile body, in particular to a steering sensor assembly. Background technique [0002] The steering torque sensor is a key component of the electric power steering system (EPS) of the car. When the steering wheel of the car is turned, the sensor converts the torque into an electrical signal and sends it to the car microcomputer controller (ECU) to determine the direction of rotation of the directional assist motor and the power assist. The size of the power ensures that the steering is light and flexible when the car is running at low speeds; and the steering is stable and reliable when driving at high speeds. [0003] The steering angle sensor is a key component of the electronic stability system (ESP) of the automobile body. When the driving car makes a sharp turn or continuously turns the direction rapidly, t...
