Description

  The present invention relates to an outer hood device for a high-speed railway vehicle that blocks a space between vehicles at a connecting portion that connects the front and rear vehicles.

  When traveling on a high-speed railway vehicle, traveling wind flows along the sides and roof of the vehicle body, so if there are irregularities on the surface of the vehicle body due to this traveling wind, intense eddy currents will occur, increasing wind noise, Moreover, running resistance increases. Therefore, in the case of a high-speed railway vehicle, if there is a space between the vehicles at the vehicle connecting portion, it will cause wind noise and running resistance to increase, which is a big problem.

  Therefore, it is a common practice to close the space between the vehicles at the connecting portion that connects the front and rear vehicles with an outer hood device.

As such an outer hood device, a fixed outer hood in the form of a strip that is fixed to the end wall of the vehicle and closes the end portion of the space between the side portions, and is movably disposed adjacent to the fixed outer hood. The strip-shaped first movable outer hood and the first movable outer hood can be held in an alignment position aligned in series with the fixed outer hood, and at least partially overlap the inner side of the stationary outer hood A first link mechanism that is supported by the end wall so as to be movable to a position; and a strip-like plate that is movably disposed adjacent to the first movable outer hood on the side opposite to the fixed outer hood with respect to the first movable outer hood. The second movable outer hood and the second movable outer hood can be held in an aligned position in series with the first movable outer hood in the aligned position and at least partially on the inner side of the first movable outer hood. A second link mechanism that is supported by a support frame on which the first movable outer hood is fixedly supported so as to be movable to an overlapped degenerate position It has been proposed (e.g. see Patent Document 1).
JP 2007-283812 A (paragraphs 0092 to 0094 and FIGS. 11 to 13)

  However, the outer hood device of this Patent Document 1 moves the first and second movable outer hoods with the first and second link mechanisms, respectively, and uses two link mechanisms. It is complicated and disadvantageous in terms of weight.

  In addition, as used in recent high-speed rail cars, the structure where the elastic outer hood is attached to both the opposite face surfaces of the front and rear vehicles, the connecting machine is connected when connecting and disconnecting the connected cars.・ Besides the separation, one end of the elastic outer hood must be attached / removed, which makes it difficult to connect and separate the vehicles.

  The present invention has a simple structure, can close the space between the vehicles in the connecting portion that connects the front and rear vehicles without increasing the weight, and can easily connect and separate the vehicles. Provide an outer hood device for railway vehicles.

According to a first aspect of the present invention, there is provided an outer hood device for a high-speed railway vehicle that closes a space between the vehicles at a connecting portion that connects the front and rear vehicles. A hood mechanism, and left and right side outer hood mechanisms that block the space between the left and right side portions of the vehicle among the spaces between the vehicles, each configured to operate independently, The left and right side outer hood mechanisms are respectively fixed outer hoods that are fixed to the front face of one of the front and rear vehicles and block the portion on the front side of the one of the vehicles in the space between the side parts, A movable outer hood provided at a distance from the fixed outer hood, a flexible outer hood provided between outer peripheral edges of the fixed outer hood and the movable outer hood, and the movable outer hood of the one vehicle Cantilevered on the wife surface, the space between the sides is reduced, and the movable outer hood is displaced toward the center of the vehicle. It said flexible outer hood that is resiliently deformed, characterized in that it comprises a link mechanism for absorbing. Here, the flexible outer hood is formed of an elastic material such as rubber.

  In this way, in the straight traveling state, the fixed outer hood, the flexible outer hood and the movable outer hood are made to be substantially flush with the outer surface of the vehicle body by the link mechanism. The space between the left and right sides of the vehicle is closed. On the other hand, in the cornering state, the space between the side portions is reduced on one side portion. At this time, the movable outer hood is displaced toward the vehicle center side by the link mechanism, and accordingly, the flexible outer hood is displaced. Since the hood is also bent and deformed toward the vehicle center side, the reduction is absorbed by the bending deformation.

  According to a second aspect of the present invention, the movable outer hood includes a movable sliding plate that extends toward the vehicle center side at an edge opposite to the side to which the flexible outer hood is coupled, It can be set as the structure by which the fixed side sliding plate corresponding to the said movable side sliding plate is provided in the wife surface of the other vehicle among vehicles. Here, the “sliding plate” is formed of a band-like rigid material such as a metal plate or a fiber-reinforced plastic plate.

  In this way, in the turning traveling state, the movable sliding plate on the movable outer hood side is displaced while sliding on the corresponding stationary sliding plate. The bending deformation toward the center side is performed, and the movable outer hood is smoothly displaced toward the vehicle center side.

  According to a third aspect of the present invention, the link mechanism includes a first link member that has one end portion rotatably attached to the end surface of the one vehicle and the other end portion rotatably attached to the movable side sliding plate. The first link member is attached to at least one of the upper and lower sides of the first link member, and one end thereof is supported to be movable in the vehicle width direction on the end face side of the one vehicle, and the other end is movable to the movable sliding plate side. A second link member supported so as to be movable in the width direction of the side sliding plate, and the first link member and the second link member intersect each other in plan view. it can.

  In this way, one end of the second link member is supported so as to be movable in the vehicle width direction on the side of the face of the one vehicle, and the other end is movable on the movable side sliding plate side. Since it is supported so as to be movable in the moving plate width direction, the movable outer hood can be displaced without difficulty.

  According to a fourth aspect of the present invention, an engaging portion projects from the first link member on the side where the second link member is provided, and the engaging portion is the second link. It is desirable to be rotatably engaged with an engaged portion formed on the member.

  If it does in this way, rotation displacement of the 2nd link member will be smoothly performed centering on the rotation part of the engagement part of the 1st link member and the 2nd link member.

  According to a fifth aspect of the present invention, the first link member is plate-shaped, and the front and rear portions of the first link member can be rotated by a pair of support brackets fixed to the end face in the vertical direction. The first link member is supported between the support bracket and the first link member for biasing the movable-side sliding plate toward the wife surface side of the other vehicle via the first link member. It is possible to adopt a configuration in which one spring material is provided.

In this way, when returning from the turning traveling state to the linear traveling state, the movable side sliding plate is moved through the first link member by the spring force of the first spring member, and the wife of the other vehicle. It is biased to the surface side. As a result, the first link member is returned to the initial position, and the link mechanism returns to the initial state.

  According to a sixth aspect of the present invention, the first link member is plate-shaped, and the front and rear portions of the first link member can be rotated by a pair of support brackets fixed to the end face in the vertical direction. An engagement member is provided at each end of the second link member, and an engaged member is provided on the end face side so that the engagement member is movably engaged in the vehicle width direction. A second spring member is provided between the engaging member and the support bracket to urge the movable sliding plate toward the end face of the other vehicle via the second link member. It is possible to have a configuration as described above.

  In this way, when returning from the turning traveling state to the linear traveling state, the movable side sliding plate is moved through the second link member by the spring force of the second spring member, and the other vehicle's wife. It is biased to the surface side. As a result, the second link member is returned to the initial position, and the link mechanism returns to the initial state.

  In the present invention, as described above, the reduction of the space between the side portions is absorbed by displacing the movable outer hood toward the center of the vehicle and flexing and deforming the flexible outer hood accordingly. With a simple structure, the space between the vehicles in the connecting portion that connects the front and rear vehicles can be closed without increasing the weight.

  In addition, the movable outer hood is only cantilevered on the end face of the one vehicle via a link mechanism and is separated from the other vehicle. Only the connecting / disconnecting operation is required, and the connecting and separating operations of the vehicle are simplified.

  Furthermore, since the flexible outer hood is bent and deformed toward the center of the vehicle in a turning state, there is no possibility that the vehicle limit will be violated even if the link mechanism breaks down.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
