Description

  The present invention relates to a connecting device for a traveling vehicle body.

  Conventionally, as a method of lowering the floor of a vehicle in order to cope with barrier-free or the like, a vehicle body 3 having no carriage is added to a vehicle body 2 having a carriage 1 with reference to FIG. 1 showing the embodiment of the present invention. It is known in rail cars, particularly trams (see, for example, Patent Documents 1 and 2) that they are connected and floating supported, and the vehicle body 3 does not have a carriage to lower the floor.

  However, if the upper and lower parts of the vehicle body are connected by spherical bearings, sufficient articulation rigidity can be obtained, and there is an advantage of avoiding the vibration problem that occurs in the case of elastic body support. When using a structure that couples the bearings with spherical bearings, there is a problem that the upper and lower loads are also distributed to the upper part of the car body, which is inferior in strength to the lower part of the car body. .

  On the other hand, in order to prevent rattling, abnormal noise generation, uneven wear, and damage due to the connection between the vehicle bodies, the bearings do not play on both of the two brackets that are connected regardless of the type, and more preferably 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, it is not suitable for the problem of machining accuracy, which is large and heavy, but for the fixed brackets of the lower connecting part, which is mostly used for flat surface processing of the mounting surface only by molding or manufacturing. Therefore, it is necessary to process the holes for fitting and holding the bearings with high accuracy, 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 together, it is difficult to stably support the vehicle body without a trolley by a vehicle body with a trolley, increasing the mounting area, increasing the number of bolts, However, it is necessary to form unevenness for slip prevention as described in Patent Document 3, which is more expensive.
