The invention discloses a coupler traction monitoring sensor and a coupler, the coupler traction monitoring sensor comprises a tail pin, the side wall of the tail pin is provided with a counter bore, and one end of the tail pin is provided with a wire outlet; the strain gauges are mounted in the counter bores; the connecting wire is located in the tail pin, one end of the connecting wire is electrically connected with the strain gauge, and the other end of the connecting wire extends out of the wire outlet. The tail pin serves as a rigid body to directly bear traction force transmitted by a vehicle and then feeds back the traction force to the strain gauge, and the service life can be prolonged. The coupler tail pin can directly replace an original coupler tail pin and serve as a coupler part and a traction force sensor, the mechanical structure of an original coupler is not changed, additional steps such as polishing, pasting and glue sealing are not needed, and installation is convenient. The tail pin directly bears the traction force transmitted by the vehicle, and the force bearing point of the sensor can more truly reflect the traction force of the coupler, so that the measured traction force data is more accurate, and the force measurement precision is improved.

    本发明公开了一种车钩牵引力监测传感器及车钩,车钩牵引力监测传感器包括尾销,尾销的侧壁开设有沉孔,尾销的一端开设有出线口;应变片,应变片安装在沉孔内;连接线,连接线位于尾销内,连接线的一端电性连接应变片,连接线的另一端从出线口伸出。尾销作为一个刚性体直接承受车辆传递的牵引力,再反馈到应变片上,可以提高使用寿命。本发明可以直接替换原有车钩中的尾销,既作为一个车钩的零部件又作为一个牵引力传感器,不改变原有车钩的机械结构,无需打磨、粘贴、封胶等额外步骤,安装方便。尾销直接承受车辆传递的牵引力,传感器的受力点能更真实地反映出车钩牵引力的大小,因此测量的牵引力数据更准确,提高测力精度。
