Sensor array for detecting rotation angle and/or torque

A sensor arrangement for detecting a parameter of mechanical components selected from the group consisting of an angle of rotation, a torque of rotating, and both, the sensor arrangement comprising first and second angle encoders securable mechanically at axially different points to a rotating component, at least one sensor disposed in a region of said angle encoders, said angle encoders and said at least one sensor being disposed such that a torsion of the rotating component is detected as a relative change in an angle between said angle encoders;

• a torsion bar located between securing points of said angle encoders;
• two bodies rotating in slaved fashion at different speeds of revolutions, said bodies being disposed on said first angle encoder on a circumference of the rotating component so that their rotational angles are detected with said sensor and from their rotational angle difference an absolute rotational angle position of the rotating component is determined, said second angle encoder being engaged with another end of said torsion bar;
• a further rotating body which engages a sleeve corresponding to said first angle encoder and corresponds to one of said first mentioned rotating bodies or the other of said first mentioned rotating bodies, so that a torque is derived from a rotating angle difference of said further rotating body of said second angle encoder and of said one and other first-mentioned rotating bodies of said first angle encoder.
