1. Apparatus for measuring and recording dynamic parameters for a driven wheel, wherein said apparatus is non-permanently mountable to the driven wheel, said apparatus comprising:

  • (a) a mechanical distortion member adapted to be drivingly interconnected between a driving force input stage and a driven wheel output stage, and a sensing means directly connected to the mechanical distortion member for conversion of mechanical distortions to electrical signals indicative of the applied torque to said mechanical distortion member;

    (b) at least one centripetal accelerometer, which rotates in conjunction with the driven wheel, for sensing the effects of dynamic angular velocity applied to the driven wheel;

    (c) a tangential accelerometer, which rotates in conjunction with the driven wheel, for sensing the effects of dynamic angular acceleration applied to the driven wheel;

    (d) a tangential accelerometer, which rotates in conjunction with the driven wheel and is oriented parallel to the rotational axis of the driven wheel, for sensing the effects of dynamic lateral angular acceleration applied to the driven wheel; and

    ,(e) means for recording the sensed signals indicative of applied torque, angular velocity, angular acceleration and lateral angular acceleration of the driven wheel.
