摘要： A torque detecting device detects a torsional torque between a first shaft and a second shaft based on a torsional displacement of a resilient member linking the first shaft and the second shaft coaxially. The torque detecting device is provided with: a magnet fixed to the first shaft; a first yoke fixed to the second shaft and arranged to be rotatable with respect to the magnet; a second yoke fixed to the second shaft and arranged to be rotatable together with the first yoke with respect to the magnet; a magnetic flux collector which collects magnetic flux; and a magnetic sensor which detects magnetic flux density. The magnetic flux collector is located to face both the first yoke and the second yoke. The magnetic sensor is located between the first yoke, from among the first yoke and the second yoke, and the magnetic flux collector, and detects the magnetic flux density between the first yoke and the magnetic flux collector.

摘要： A transmission includes an input shaft and an output shaft, the input shaft selectively accepting a torque input from a prime mover, and the output shaft selectively providing torque output to a driveline. A controller determines a shaft displacement angle representing an angle value of rotational displacement difference between at least two shafts of the transmission, and performs a transmission operation responsive to the shaft displacement angle.

摘要： An inductive power transfer system for the shaft mounted electronics of a rotary torque application includes a pair of planar PCB coils having spiral copper traces on the surfaces of one or more layers of PCB substrate material. A primary coil surrounds but is not connected to a steel torque transmission shaft for rotation therewith. A secondary coil is mounted for rotation with the shaft and is inductively linked with the primary coil by means of a close proximity parallel mounting relationship wherein both coils are coaxial with the torque transmission shaft and use the shaft as a partial low permeability core.

摘要： A drive-train of a vehicle which at least includes a drive motor (1) and a transmission (2). The drive-train has at least one torque sensor (6, 6A) which is provided for the purpose of controlling a drive component of the drive-train. The torque sensor (6, 6A) is integrated in a transmission component in order to determine, at the time, the torque applied to the transmission component.

摘要： An interaction force detection apparatus includes a sensor, a driving element, a moving element, and a connecting element. The connecting element is connected to the driving element and the sensor. The driving element is adapted to interact with the moving element, so as to generate a pair of forces. The pair of forces includes a first force and a second force, and a magnitude of the first force is equal to that of the second force. The sensor detects the first force exerted on the driving element, and the second force is exerted on the moving element to generate a movement.

摘要： A torque sensor is provided with a torsion bar which converts torque applied between a first shaft and a second shaft into a torsional displacement. A multipole magnet is fixed to one end side of either the first shaft or the torsion bar and in which N poles and S poles are magnetized alternately in a circumferential direction. A plurality of first yokes is provided in the circumferential direction on a radially outer side of the multipole magnet. A plurality of second yokes is provided in the circumferential direction on the radially outer side of the multipole magnet in such a way that each second yoke is sandwiched between two first yokes. A set of magnetic flux collecting members includes a first main body portion and a second main body portion, and forms a magnetic circuit in conjunction with the plurality of first yokes and the plurality of second yokes in a magnetic field generated by the multipole magnet. A magnetic sensor is provided radially outside the first main body portion and the second main body portion to detect a magnetic flux density generated in the magnetic circuit
