Abstract: A powertrain incorporates a link shaft between the transmission output shaft and downstream components in order to facilitate use of a torque sensor. The link shaft includes an inner section splined to the output shaft and an outer section treated to produce a magnetic field that varies based on transmitted torque. The inner section and outer section are separated by a circumferential gap that directs the torque past the treated surface. Use of the link shaft eliminates the need to directly treat the transmission output shaft. Separating the spline and the treated surface radially reduces the axial length required for torque sensing and allows commonality among variants with and without torque sensors and between two wheel drive and four wheel drive variants.
