Abstract
An electromechanical brake tightening device for a rail vehicle, includes a brake actuator to apply and release brakes. The actuator has a power converter to convert energy supplied by the brake actuator to a brake application movement. The power converter includes a shear force measuring bolt and/or a brake lever, arranged in a power transmission path of the converter to measure braking power.
