A rail vehicle having a) a friction-force-based brake device that is controlled by an electronic control device and has at least one disc brake device that is associated with a wheel or a wheel set, fixed by a bracket to a bogie and comprises at least one brake pad that comes into and out of frictional contact with a brake disc in order to apply and release the brake, a brake calliper connected to the at least one brake pad and a brake housing on which the brake calliper is mounted, a frictional brake force (F HR) and/or a frictional brake torque (M HR) being generated when the at least one brake pad comes into frictional contact with the brake disc, b) a sensor device that comprises at least one sensor, directly or indirectly measures the frictional brake force (F HR) and/or the frictional brake torque (M HR) or a value derived from the frictional brake force (F HR) and/or the frictional brake torque (M HR), generates an electrical force signal dependent on the frictional brake force (F HR) measured and/or the frictional brake torque (M HR) measured or on the derived value measured and sends it to the electronic control device, characterised in that c) the brake housing is mounted on the bracket in an articulated manner by means of a slide bearing on one side and by a strut bearing the at last one sensor of the sensor device on the other such that as a result of the frictional brake force (F HR) arising from the frictional contact between the at least one brake pad and the brake disc a torque is generated on the brake housing about the slide bearing, a resulting reaction force is generated in the strut and measured directly or indirectly by a sensor of the sensor device and the sensor device generates the force signal based on the reaction force. a) a friction-force-based brake device that is controlled by an electronic control device and has at least one disc brake device that is associated with a wheel or a wheel set, fixed by a bracket to a bogie and comprises at least one brake pad that comes into and out of frictional contact with a brake disc in order to apply and release the brake, a brake calliper connected to the at least one brake pad and a brake housing on which the brake calliper is mounted, a frictional brake force (F HR) and/or a frictional brake torque (M HR) being generated when the at least one brake pad comes into frictional contact with the brake disc, b) a sensor device that comprises at least one sensor, directly or indirectly measures the frictional brake force (F HR) and/or the frictional brake torque (M HR) or a value derived from the frictional brake force (F HR) and/or the frictional brake torque (M HR), generates an electrical force signal dependent on the frictional brake force (F HR) measured and/or the frictional brake torque (M HR) measured or on the derived value measured and sends it to the electronic control device, characterised in that c) the brake housing is mounted on the bracket in an articulated manner by means of a slide bearing on one side and by a strut bearing the at last one sensor of the sensor device on the other such that as a result of the frictional brake force (F HR) arising from the frictional contact between the at least one brake pad and the brake disc a torque is generated on the brake housing about the slide bearing, a resulting reaction force is generated in the strut and measured directly or indirectly by a sensor of the sensor device and the sensor device generates the force signal based on the reaction force.
