  By the way, in order to prevent rattling, noise generation, uneven wear, and damage due to the connection between the vehicle bodies, there is no play in both the two brackets that are connected to each other regardless of the type of bearings. It is necessary to support and hold the position with a high degree of fitting, which is about the same level as that of fitting. For that purpose, bearings are fitted to brackets that are large and heavy and are not suitable for processing accuracy, and are mostly used for flat surface processing of mounting surfaces. Therefore, it is necessary to process the holes to be held with high precision, and the manufacturing cost increases.

  In addition, it is difficult to align the brackets that have been fixed to the vehicle body with the bearings or the bearing members that constitute the brackets with high precision fitting or press fitting as described above. It ’s difficult. Therefore, as described in Patent Documents 2 and 3, the bracket is fastened to the vehicle body with a bolt so that necessary alignment can be performed in a state where the bolt is loosened. However, when the bolts are loosened, the position and posture of the bracket and the entire equipment member to the bracket are unstable, and the whole is heavy and difficult to handle. Therefore, the connecting operation is still not easy and the work efficiency is not improved.

  Also, by connecting the brackets that are bolted to each other, it is difficult to stably support the body without a trolley with a body with a trolley, increasing the mounting area, increasing the number of bolts, It is necessary to form unevenness for preventing slipping as described in Patent Document 3, which is more expensive.

  Further, the connection of the vehicle bodies 2 and 3 via the bearing 6 as described above is performed in the same manner between all the vehicle bodies 2 and 3 as shown in FIGS. The connection in the other part adopts various things adapted to the place. FIG. 1 shows a part, and FIG. 4 shows the whole in a five-series vehicle, between a vehicle body 2 having a carriage 1 shown at the left end of the figure and a vehicle body 2 without a carriage supporting it, and the vehicle body 2. And a bracket 31 that is bolted so that the position can be adjusted on the vehicle body 2 side, and a left and right bolted so that the position can be adjusted on the vehicle body 3 side. The movable bracket 34 connected to the bracket 32 via the spherical bearing 33 is connected via the spherical bearing 35 so that the upper parts of the vehicle bodies 2 and 3 are connected to each other and the yawing between the vehicle bodies 2 and 3 is allowed to move forward and backward. The left and right loads are transmitted and the up and down loads are cut off. Even between the vehicle body 2 having the carriage 1 shown at the right end of the figure and the next carriage 3 supported by the vehicle body 2, it is possible to adjust the position to the vehicle body 3 side with respect to the bracket 31 bolted so that the position can be adjusted to the vehicle body 2 side. The movable brackets 34 connected to the left and right brackets 32 that are bolted in this way via spherical bearings 33 are connected via spherical bearings 35 so that the upper parts of the vehicle bodies 2 and 3 are connected to each other. The front and rear, left and right loads are transmitted while allowing the yawing to be interrupted, and the vertical loads are cut off.

  On the other hand, between the vehicle body 2 having the central carriage 1 and the vehicle body 3 on the right side thereof, the brackets 36 and 37 bolted to the left and right of the upper part thereof are connected via the spherical bearing 39 by the anti-roll bar 38. Thus, the upper parts of the vehicle bodies 2 and 3 are connected to each other so that the right and left and rolling loads are transmitted while allowing pitching and yawing between the vehicle bodies 2 and 3.

  As a result, in a tram where the three vehicle bodies 2 with the carriage 1 and the two vehicle bodies 3 without the carriage are connected to each other, the vehicle has good running characteristics having yawing and pitching characteristics while obtaining the connecting rigidity that moderately suppresses rolling. It is said.

  In addition, the vertical load is blocked by the movable bracket 34 because the floating support of the vehicle body 3 by the vehicle body 2 is slightly submerged due to insufficient rigidity of each bracket, but between the brackets 31 and 32 between the vehicle bodies 2 and 3. It is possible to respond by tilting following the level difference that occurs, and it is not damaged or drowned. Further, between the brackets 41 and 42 that are bolted so that they can be extended with respect to the vehicle bodies 2 and 3 even on the left and right of the connecting portion between the vehicle bodies 2 and 3 using the movable bracket 34, a spherical bearing 44 is interposed between the brackets 41 and 42 by the yaw damper 43. It also has a connected articulated structure that improves running stability at high speeds. FIG. 5 shows a structural example of the spherical bearings 33, 35, 39, 44.
