The invention provides a force-measuring brake-shoe for a railway vehicle. The force-measuring brake-shoe is simple in structure, and capable of conducting measurement on static brake-shoe force and dynamic brake-shoe force; the detection precision is high. The force-measuring brake-shoe comprises a force-measuring sensor and at least two braking members, wherein the braking members are connected with the force-measuring sensor. The braking members are distributed at intervals in the circumferential direction of the circumference where a vehicle wheel tread is located, and capable of pressing the vehicle wheel tread when the vehicle is braked. The force-measuring sensor is used for detecting the brake-shoe force which acts on the vehicle wheel tread by the braking members, and the force-measuring sensor does not make contact with the vehicle wheel tread. According to the force-measuring brake-shoe for the railway vehicle, the braking of a vehicle wheel is achieved through the braking members, so that damage to the force-measuring sensor is avoided. In addition, relative motion between the braking members and the vehicle wheel tread is allowed in the braking mode so as to achieve the measurement on the brake-shoe force in a dynamic state, so that the obtained detection value of the brake-shoe force is made more accurate and effective. The at least two braking members are arranged, so that the stress is evener through the two-point contact or multipoint contact, and the measuring error is reduced.
