ABSTRACT:
A vertically adjustable emergency support for the bodies of, for example, rail vehicles. Due to wear of the wheel tires, the bogie frame and the car body supported on it tend to descend. In the case of emergency supports in the region of the center pivot, where access is difficult, it is proposed, in order to compensate for this drop, to connect the striker plate which faces an emergency spring at a distance "w" to a box underneath which as vertically guided via guide elements on sliding-contact liners of a cut-out in the bogie frame. If the distance "w" increases due to wear of the wheel tires, an adjustment has to be made by raising the box via a plate connected to the center pivot. Plates of a thickness which compensates for the wear are inserted between the box and abutments which are connected to the bogie frame. After securing the plates via bolts, the car body is lowered again, whereupon the distance "w" is restored. In another embodiment for fixing the box relative to the bogie frame, after the box has been moved upwards far enough to restore the clearance "w" , it is fixed in its position by a saw tooth connection including saw teeth engaging in a positive connection produced between the box and the bogie frame.
