CONTACTLESS TORQUE SENSOR - Mechatronic Principle and Prototype Development for Automotive Applications

Manfred Brandl, Franz Haas, Reinhard Marik

Abstract

In this paper fundamentals and the prototype development of a new contactless torque sensor are presented. The whole device can be divided into a mechanical and an electromagnetic system. The prototype is designed for the torque range of an electric power assisted steering. The basic idea is the transformation of the shaft twist under torque load into a translational movement of the middle part of the sensor sleeve that is measured by an inductive measuring device. An additional aspect is the low cost manufacturing and assembling of the whole system. The interface electronics ensures high linearity and accuracy and is therefore very suitable for this application. This new sensor concept is very robust and self-compensating for all kinds of relative positioning tolerances ranging from temperature change to external forces.
