A torque sensor includes an input rotation component, which rotates with a steering column input shaft and is provided with a first conducting part, an output rotation component which rotates with a steering column output shaft and is provided with a second conducting part, and an electromagnetic carrier positioned in a positionally fixed manner and provided with a magnetic field generating component and a magnetic field detection component. The magnetic field generating component generates a magnetic field penetrating the first conducting part and the second conducting part, the magnetic field detection component detects a change in the magnetic field caused by a change in the positions of the first and second conducting parts in the magnetic field when the steering column is under torsional stress, and the steering torque is determined on the basis of the detected change in the magnetic field.

Torque sensor, steering angle sensor and corresponding integrated sensor and monitoring system

A torque-angle sensor includes a torque sensing unit, an angle sensing unit, and a PCB. The torque sensing unit includes a signal input rotor and a signal output rotor. The angle sensing unit includes a driving gear and a driven gear that is fitted round and fixed to one of the signal rotors. The PCB has a torque magnetic field generating unit, an input shaft signal collecting unit, and an output shaft signal collecting unit that sense a rotation angle and torque of the signal rotors. The PCB has an angle magnetic field generating unit and an angle collecting unit that sense a rotation angle of the driving gear and the driven gear. The torque magnetic field generating unit, the input shaft signal collecting unit, the output shaft signal collecting unit, the angle magnetic field generating unit, and the angle collecting unit are configured as coils formed by printed circuits.

Torque-angle sensor for monitoring a steering situation of a vehicle

A torque-angle sensor is mounted on a steering column with a system casing and configured to detect a steering torque and angle of steering wheel steering of a vehicle. The torque-angle sensor includes a top cover, a torque sensing unit, an angle sensing unit, a PCB, a signal output terminal, and a sensor casing. The top cover includes a body, a first fitting part, and second fitting part. The first fitting part is a flange extending from the body towards the sensor casing, and fitted to the sensor casing. The second fitting part is a flange extending in a radial direction and/or axial direction of the body, and fitted to the system casing. In a radial direction of the body, a distance between the second fitting part and a center of the body is greater than a distance between the first fitting part and the center of the body.
