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. <EOS>
