  • 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.

  • Publication number: 20170190338
    Abstract: A mounting structure for equipment compartment bottom plate is provided. The bottom plate is detachably connected to a skeleton boundary beam of the equipment compartment. A sliding rail is fixedly connected to a side of the bottom plate where the bottom plate is lap-jointed to a skeleton lateral beam of the equipment compartment. One of the sliding rail and the skeleton lateral beam is provided with a recess and the other is provided with a protrusion engaged with the recess. In the mounting structure, the connection of the bottom plate and the skeleton lateral beam is achieved by the engagement of the recess and the protrusion. Therefore, connecting pieces for connecting the bottom plate and the skeleton lateral beam are removed and the number of the connecting pieces is significantly reduced.
