Patent ID: 7813857

Claim:
A transfer case for a vehicle, comprising: a first shaft adapted to be coupled to a first driveline; a second shaft adapted to be coupled to a second driveline; a torque transfer device including a clutch disposed between said first and second shafts and a power-operated actuator for actuating said clutch; a first sensor portion being formed from a magnetoelastic material and coupled to said first shaft; a first magnetoelastic torque sensor surrounding said first sensor portion; a second sensor portion being formed from a magnetoelastic material and coupled to said second shaft; a second magnetoelastic torque sensor surrounding said second sensor portion; and a control system regulating actuation of said clutch based on first torque signals from said first torque sensor and second torque signals from said second torque sensor to achieve a target torque distribution between said first and second drivelines.
