(7a1,. a': Disc brake for the vehicle wheel of an ächienenfalxzeug®. The invention relates to a disc brake for the vehicle wheel of a rail vehicle. According to DBP -1 153 412 , the combination of a disc brake with the actuating device for one that acts on the wheel running surface. Cleaning block known, which has a compressed air cylinder connected to the brake cylinder for its actuation - on one piston rod end of which the cleaning block is seated, the task is to keep the wear of the cleaning block as low as possible. Means are therefore provided in a further embodiment The cleaning block only comes into contact with higher brake pressures. The Bü.akhalten de® 12, utz # hl, otzes at lower pressures serves to protect it Pederkrait adjustable'Yentil, which turned into the newspaper is, . In the drawing ot an embodiment according to the invention schematic. shown,. - A compressed air system leads from a brake control system (not shown) line 1 into the cylinder chamber 3 @ of a compressed air cylinder 5, its cylinder base 7 at a point 9 on the vehicle frame 11 pivotable about an axis perpendicular to the plane of the drawing is articulated. The piston 13 of the air cylinder 5 is over a piston rod 15 at one end of a brake lever 17 hinged, which carries a brake shoe 19 @ at its other end. At point 9, another brake lever 21 is hinged, the one second, the brake shoe 19 opposite brake shoe 23 ' carries. Are roughly in the middle of their longitudinal extension. the two brake levers 17 and 21 by a pull rod 25 articulated on both. connected to each other * Located between the brake shoes 19 and 23 ; I the friction surfaces of a disc brake, which come from the side flanks 27 of the tire 29 of a rail vehicle wheel 31 and possibly the radial surfaces of not shown, .die Side flanks 27 widening and used in the wheel tires Brake rings exist. On the tie rod 27 is one of the Compressed air line 1 from ventilable and with its ventilation a cleaning block 33 on the purchase surface 35 by means of a piston of the wheel tire, 29 pressing air cylinder 37 fastened® The Drucklüftzylnder 37 is with the cylinder space 3 by a .Zeitung 39 connected, in which a pressure control valve 40 is installed. (fall @) The piston 41 - on its piston rod 42. the cleaning block 3.3 seat " is loaded by a spring 38, whose characteristics for the Use of the Pützkelben @ 3 'is decisive. (7a1 ,. a ':
