摘要：Tension in a cable of a parking brake assembly is measured by way of a forcemeasuring transducer device which is removably attachable to the lever arm bracket ofthe assembly located in the cabin of the automobile. The lever arm is lifted and thetransducer device is positioned such that the arm presses against the load receivingsurface of the transducer, such pressure being a function of the cable tension. Preferably,the transducer includes at least one flexure element connected to the load receivingsurface operative to convert the force applied by the lever arm to electrical signals as afunction thereof. The transducer device incorporates a retractable pin which engages anopening in the mounting bracket for the lever arm. The transducer is thus wedgedbetween portions of the bracket and a pawl on the lever arm in a predeterminedorientation such that the forces exerted by the pawl are applied generallyperpendicularly to the flexure element. The invention finds particular utility in themanufacture of automobiles where the parking brake cable is not accessible underneaththe body of the car.
