  • Railway vehicle and head vehicle barrier-removing device thereof
    Patent number: 9889864
    Abstract: A railway vehicle and a head car cowcatcher thereof are provided. The head car cowcatcher includes a flow guiding plate; a front-end frame mounted at a front end of an inner side surface of the flow guiding plate; and longitudinal sills mounted at two sides of the inner side surface of the flow guiding plate. Two ends of the front-end frame are respectively connected to the longitudinal sills located at the two sides. The rigidity of a connecting part of the longitudinal sills and the front-end frame is smaller than the rigidities of any parts of the longitudinal sills and the front-end frame. When obstructions are cleared or a train collision occurs, the connecting part of the front-end frame and each of the longitudinal sills would be largely deformed if the impact force the cowcatcher bears is beyond the maximum load the cowcatcher can bear.
