Abstract

A brake application for a rail vehicle brake includes a brake actuator for application and release of the rail vehicle brake. Also included is a force converter for converting energy supplied by the brake actuator to a brake application movement. The force converter includes: (1) a shearing force measuring bolt arranged in a power transmission path; (2) at least one measuring sensor measuring breaking force either indirectly or directly; and (3) at least two mutually swivellable force transmission elements having passage openings. The shearing force measuring bolt forms a hinge bolt of a hinge, which hinge bolt penetrates the passage openings.
