A tilt in a three-dimensional direction is given. Further, although not shown in the drawings, an integrated structure in which the mounting seat 44 and the adjustment seat 46 are integrated with the door rail fixture 28 may be employed.
In the illustrated example, five door rail fixtures 28 are used, but the number and layout thereof are appropriately adjusted as necessary.

According to the embodiment of the present invention configured as described above, the following operational effects can be obtained. First, a load test apparatus 20 for a railcar side door closer according to an embodiment of the present invention includes an opening frame body 22 simulating a vehicle structure around a side door, a side door door closer 14 and a side door. The load applied to the side door door closing device 14 can be reproduced by the load applying means 24, 26, 28 fixed to the opening frame body 22. As a result, the side door door closing device 14 can be reproduced. And the periphery of the side door 12 contributes to the optimization of the vehicle structure.
Specifically, the side door 12 is driven by the lateral pressure applying device 24 that is in contact with the side door 12 when the side door 12 is opened and closed and when the side door 12 is fully closed. A load is applied to the side door door closing device 14 via the.

  The lateral pressure applying device 24 includes a contact 36 provided on a distal end portion of a movable rod 30 that is held on the opening frame 22 so as to be separated and approachable from the outside of the side door 12 toward the surface of the side door 12. The pull-in rail 34 fixed to the outer surface of the door 12 so as to extend in the opening / closing direction of the side door 12 is engaged / disengaged from the end of the pull-in rail 34 to the pull-in rail 34 according to the opening / closing operation of the side door 12. It is something to be made. As a result, the lateral pressure applying device 24 always comes into contact with the side door 12 driven by the side door door closing machine 14 when the side door 12 is opened and closed and in the fully closed state. At this time, it is possible to freely adjust the force of the movable rod 30 urging the side door 12 toward the outside by the load adjusting means 32. When the side door 12 is opened and closed and in the fully closed state, it is possible to apply lateral pressure to the side door 12 outward in the vehicle width direction.

  Further, a plurality of movable rods 30 arranged side by side in the opening / closing direction of the side door 12 on the beam 22c fixed so as to cross the opening of the opening frame 22 open / close the side door 12 on the outer surface of the side door 12. With respect to the pull-in rail 34 fixed so as to extend in the direction, the pull-in rail 34 is sequentially engaged and disengaged from the end 34b of the pull-in rail 34 according to the opening / closing operation of the side door 12. As a result of the disengagement of the plurality of movable rods 30 with respect to the pull-in rail 34, lateral pressure is always applied to the side door 12 outward in the vehicle width direction when the side door 12 is opened and closed and in the fully closed state. It becomes possible to do.

Further, the roller 36 of the movable rod 30 contacts the guide surface 34a of the pull-in rail 34 having an L-shaped cross section, pulls the side door 12 outward in the vehicle width direction, and the guide surface 34a of the pull-in rail 34. As the roller 36 rotates, the side door 12 can be opened and closed smoothly, and the lateral pressure applied to the side door 12 toward the outside in the vehicle width direction can be accurately increased due to the behavior of the vehicle and the influence of congestion in the vehicle. Can be reproduced.
In addition, the slope surface 34b formed at the end of the pull-in rail 34 in the side door opening direction guides the roller 36 to the pull-in rail 34 along with the operation of the side door 12 when the side door 12 is closed. The state of contact with the pull-in rail 34 is recovered. Further, even when the side door 12 is opened, the roller 36 is smoothly opened from the slope surface 34b at the end of the pull-in rail 34 together with the operation of the side door 12, so that the side door 12 can be opened and closed smoothly. Yes.

Further, the load applying means includes a side door door closing fixture 26 for fixing the side door door closing device 14 to the cover portion 22 a of the opening frame body 22. Via the adjustment seat 40 and the mounting seat 42, the side door door closing machine 14 can be fixed to the cover portion 22 a of the opening frame body 22. Then, the shape of the adjustment seat 40 or the mounting seat 42 can be adjusted to reproduce the bending that occurs in the vehicle structure around the side door, and a load can be applied to the side door door closing device 14.
In addition, since one of the contact surfaces of the adjustment seat 40 and the mounting seat 42 is inclined with respect to the mounting surface of the adjustment seat 40 of the cover portion 22a of the opening frame body 22, the vehicle structure around the side door is provided. The bending that occurs can be reproduced by the inclination of the adjustment seat 40 and the mounting seat 42, and a load can be applied to the side door door closing machine 14.
Moreover, by adjusting the shape of each of the side door door closing fixtures 26, a plurality of the side door door closing fixtures 26 are arranged in the longitudinal direction of the roof portion 22a and the side door door closing device 14, The bending that occurs in the vehicle structure around the side door can be reproduced over the entire side door door closing device 14 and a load can be applied to the side door door closing device 14.

  Note that the side door door closing fixture 26 may have an integrated structure in which the adjustment seat 40 and the mounting seat 42 are integrated. In this case, by inclining the contact surface of the side door door closing fixture 26 with the side door door closing device 14 with respect to the contact surface with the cover portion 22a of the opening frame body 22, Can be reproduced by the inclination of the side door door closing fixture 26 and a load can be applied to the side door door closing device 14.

  Further, the load applying means includes a door rail fixture 28 for fixing the door rail 16 used together with the side door door closing device 14 to the threshold portion 22b of the opening frame 22. The door rail fixture 28 is for fixing the door rail 16 to the threshold portion 22 b of the opening frame body 22 via the mounting seat 44 and the adjustment seat 46. Then, the shape of the mounting seat 44 or the adjustment seat 46 is adjusted to reproduce the bending generated in the vehicle structure around the side door, and the load applied to the door rail 16 is also taken into consideration, and the load is applied to the side door door closing device 14. be able to.

In addition, since one of the contact surfaces of the mounting seat 44 and the adjustment seat 46 is inclined with respect to the mounting surface of the mounting seat 44 of the threshold portion 22b of the opening frame body 22, the vehicle structure around the side door is obtained. The bending that occurs can be reproduced by the inclination of the mounting seat 44 and the adjustment seat 46, and a load can be applied to the door rail 16.
In addition, by adjusting the shape of each of the door rail fixtures 28 arranged in the longitudinal direction of the threshold portion 22b and the door rail 16, the deflection generated in the vehicle structure around the side door is reproduced over the entire door rail 16. Thus, a load can be applied to the door rail 16.

Further, the door rail fixture 28 may have an integrated structure in which the mounting seat 44 and the adjustment seat 46 are integrated. In this case, the contact surface of the door rail fixture 28 with the door rail 16 is tilted with respect to the contact surface with the threshold portion 22b of the opening frame body 22, thereby causing the deflection that occurs in the vehicle structure around the side door. Can be reproduced by the inclination of the door rail fixture 28 and a load can be applied to the side door door closing device 14.
The load test apparatus 20 according to the embodiment of the present invention can more accurately reproduce the load applied to the side door door closing device 14 by the synergistic effect of the load applying means 24, 26, 28, As a result, it will be understood that this contributes to the optimization of the vehicle structure in the periphery of the side door door closing device 14 and the side door 12.
