Abstract
A torque sensor for use with an automotive steering system. The sensor includes a driving shaft, a driven shaft, a sleeve cylinder fitted over one of the shafts so as to be rotatable and axially movable, a differential transformer, first and second connector members, a spring, and a torsion bar. The amount of axial movement of the sleeve cylinder is detected by the transformer. The connector members are inclined in opposite directions within a plane parallel to the axis of the shafts. One end of the first connector member is connected to the cylinder, while the other is connected to the driving shaft. One end of the second connector member is connected also to the cylinder, the other being connected to the driven shaft. Torque is transmitted from the driving shaft to the driven shaft via the torsion bar. The spring is mounted between one of the shafts and the sleeve cylinder.
