Abstract: Disclosed is a car coupling hood device including a pair of hoods provided between a pair of car bodies to be coupled together, each of the hoods having one end secured to an adjacent car body, and an intermediate frame for coupling the other ends of the hoods together. The hood device incorporates a plate member coupled to the intermediate frame and provided in either the ceiling portion or the bottom portion of the hood device, or in both portions, and regulating means for preventing the movement of the plate member by the engagement therewith when both the car bodies are displaced relative to each other in the lateral direction thereof by more than a predetermined value.

Abstract: This invention relates to a superior suppressing of vibration in a car body when a vehicle runs on a straight railroad and a curvilinear railroad. The invention is comprised of a fluid pressure-acting mechanism arranged between the car body and the truck along with springs for positively controlling a force acting between the car body and the truck with the supplied pressure fluid, an acceleration detector for detecting an acceleration of the car body, and means for determining a displacement generated relatively between the car body and the truck under a steady acceleration acting against the car body.
