A load cell for measuring the torque and/or thrust forces in a driveline having a universal coupling joint, such as the drive shaft of an automobile. The load cell is designed to replace the standard cross element in the U-joint. Due to the operative association of the load cell with the driveline and the particular strain gage arrangement disclosed, the load cell is capable of accurately measuring the axial force and rotational torque transmitted through the driveline.

A force measurement transducer for an automotive driveline of the type comprising plural shaft sections: an integral body of high modulus of elasticity material having a substantially annular configuration, said body including four uniformly spaced rigid sectors conjoined by flexure struts of substantially lesser cross-section than said sectors, each of said struts being oriented at right angles to the two next adjacent struts, first and second oppositely radially extending connector elements integral with first and second diametrically opposite sectors, respectively, for pivotally securing said transducer to one driveline shaft section, third and fourth oppositely radially extending connector elements integral with third and fourth diametrically opposite sectors, respectively, for pivotally securing said transducer to another driveline shaft section, said transducer body being of such dimension as to fit substantially within the cross-sectional area of said shaft sections whereby said transducer body is capable of acting as a cross-member of the universal joint in said driveline, and strain gage resistor means mounted on said flexure struts and electrically interconnected to produce an output quantity representing forces in said transducer body caused by operation of said driveline.
