  • Patent number: 11021176
    Abstract: An energy absorption device configured to be provided at a front end of a train includes a coupler seat, a support base, a crush pipe, a coupler, a guide member, an energy absorption component and an anti-climbing assembly. The support base is fixedly arranged at the front end of the train; the crush pipe is fixed to the coupler seat; a connecting end of the coupler is inserted into the crush pipe and is slidable with respect to the crush pipe; the guide member has one end fixed to the coupler seat, and another end inserted into the support base and slidable with respect to the support base; the guide member limits an oscillation of the crush pipe; the energy absorption component is provided between the coupler seat and the support base; and the anti-climbing assembly is fixedly arranged on the support base and is compressible.

  • 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.
