  • Torque sensor
    Patent number: 6857500
    Abstract: A torque sensor apparatus and method for use with an automotive steering system is disclosed. The torque sensor apparatus includes a shaft having a primary shaft coaxially connected to a secondary shaft and a first substrate operably connected to the primary shaft oriented substantially perpendicular to an axis defining the shaft. A second substrate is operably connected to the secondary shaft oriented substantially perpendicular to the axis. First and second substrates each have an aperture therethrough configured to receive an alignment pin therethrough. First and second substrates are substantially parallel to each other defining an electrical interface therebetween that is configured to generate a signal indicative of an amount of torque applied to the shaft.
    Type: Grant
