    Abstract: A power transmission apparatus includes a shaft, a driving plate, a first driven plate, and a sensor device. The driving plate is disposed on the shaft and rotates with the shaft. The driving plate includes a first block that has a driving surface on it. The first driven plate is disposed on the shaft and capable of moving along the shaft. The first driven plate includes a second block that has a driven surface corresponding to the driving surface. The sensor device is disposed close to the first driven plate for detecting the movement of the first driven plate along the shaft. When the shaft rotates together with the driving plate, the driving surface compels the driven surface to rotate and simultaneously move away from the driving plate along the shaft, and the movement along the shaft is detected by the sensor device.

    Abstract: A torque sensing device includes a rotating component configured to rotate about an axis of rotation and a first sensor positioned adjacent to the rotating component to sense instantaneous angular position of the rotating component at a first location. A second sensor is positioned adjacent to the rotating component radially inboard of the first sensor to sense instantaneous angular position of the rotating component at a second location. A controller is operably coupled to the first sensor and the second sensor. The controller determines a relative phase shift between a first signal generated by the first sensor and a second signal generated by the second sensor to calculate an output proportional to a torque applied to the rotating component.

    Abstract: Aspects of the present invention are directed to using surface acoustic wave (SAW) sensors mounted on a disc coupling component in a powertrain to measure the torque generated by an automobile engine. The sensor may be positioned and oriented on the disc coupling component so that the phase velocities of SAWs propagating through active elements of the SAW sensors are aligned with principal strain components due to torque in the disc coupling component. The torque may be calculated by determining the difference between resonant frequencies of the active elements to suppress common-mode interference factors. In addition, SAW resonant frequencies may be communicated in a non-contacting manner by utilizing rotary and stationary couplers employing radio frequency (RF) signals. Moreover, SAW sensors may be activated and interrogated by employing targeted RF pulses having different carrier frequencies at or near respective resonant frequencies of each resonator in a SAW sensor.

    Abstract: Two external rings and an internal ring form an assembly that is connected to a column so it rotates with it, to which column the torque to be measured is applied. Elastically deformable members connect the internal ring to one external ring, and the other external ring remaining essentially unstressed. A measurement device, such as, for example, a probe having at least one with Hall effect device, measures relative displacement of the two external rings to determine the torque applied. The invention also concerns the steering devices equipped with such torque sensors, for example, for power or assisted steering.
