Abstract
A compact power steering system is suitable for small vehicles. A torque sensor on a steering shaft detects operator intention to turn. In response, a motor provides torque to assistance in rotating the steering shaft. A strain wave gear set multiplies the motor torque. A coupler having a torsional isolator links the gearbox output to the steering shaft.
