With the essentially conical wheel running surface 5 When compressed air is applied to the brake cylinder, the rail vehicle wheel 2 is on a surface 12, the brake pad 8 is provided with a pressure force against the wheel brake acting in the direction of the surface 6 of a running rail 7 5 a brake pad 8 running surface 5 is pressed. Since the angle β is greater than the pressure, which is the angle \ on its rail travel 15, there is a side facing away in the direction of the vehicle wheel 2 with two bearing eyes 9 acting towards the flange 3 and 9 'between the bearing eyes 9 and element, which engages the brake pad 8 in the direction of 9 ', a piston rod 10, which seeks to move laterally towards a flange 3. The brake pad 8 charged with compressed air via a pipe connection 11 runs against the wheel flange 3, to which the impactable brake cylinder 12 belongs. The piston * o and the side force component is taken up by this rod 10 via a to an axis 13 of the. If the opposite pin 14, which is also perpendicular to the brake cylinder 12 and which is connected to the shaft 1, is provided with a similar friction brake on the bearing eyes 9 and 9 'in a vertical plane 10 35 friction brakes over the two rail vehicles on the brake pad 8 one wheels in the direction of its axis and the shaft 1 off. The reaction force of the 13 acting pressure force from. The axis 13 runs the brake cylinder 12 is horizontally and via the pressure bolt transferred to a dash-dotted line 24 and the abutment 25 th on the vehicle frame, an axis 15 of the rail vehicle wheel 2 20.

perpendicularly intersecting center plane 16 at an acute angle β having the rail vehicle wheel 2, the axis 13 being inclined axially displaceably on the rail vehicle relative to the wheel flange 3 in the direction of the wheel set. The angle ', is supported, the brake pad is able to move the lateral displacement greater than the angle \ that can also be followed between exercises of the rail vehicle wheel 2. The vertical line 17 indicated by dash-dotted lines on the brake cylinder 12 swivels around its wheel running surface 5 and the center plane 16 of the slide 35 mounting on the pressure pin 24, and the pendulum lever inner vehicle wheel 2 occurs. On the bolt 14, 18 and 18 'are essentially pivoted laterally, two of the bearing eyes 9 and 9' within the scope of their play on the side. It is important to borrow vertically upwardly extending pendulum levers that the angle β is articulated at maximum Seitenver-18 and 18 ', which close to their upper shift of the rail vehicle wheel 2 outwards, ends with a bolt 19 on a vehicle frame 40 so opposite to the direction of the arrow A in F i g. 2, men 20 essentially in an axis 13 which decreases at most to the size of the angle \

The storage of the pendulum wheel set without lateral displacement on the rail lever 18 and 18 'on the bolts 14 and 19 is mounted on the vehicle, it is useful if the formed with play so that the pendulum lever 18 and 45 angle β to the during the period of use of the 18 'are also slightly pivotable perpendicular to the above-mentioned plane of the rail vehicle wheel 2 which may occur. At a floor 21 corresponds to angle \. In this context, two brackets 22 and 22 'are to be pointed out to the brake cylinder 12 that the angle is provided between which, by means of prestressed wear during operation of the rubber rail elements 23 and 23', a pressure pin 24 is attached to a vehicle wheel 2 changes.
