Description

Bei Vollbelagscheibenbremsen mit umlaufendem, außen veripp­ tem Bremsgehäuse wird der überwiegende Teil der Bremswärme durch Konvektion abgeführt. Diese Wärmeübertragung steigt mit zunehmender Relativgeschwindigkeit der Kühlluft an. Deshalb haben sich Vollbelagscheibenbremsen besonders bei Kettenfahr­ zeugen bewährt, bei denen sie auf den, gegenüber den Ketten­ antriebsrädern stark übersetzt umlaufenden, Antriebswellen angeordnet sind. Infolge des dann reduzierten Bremsmoments können sie relativ klein und leicht bemessen werden und verbleiben wegen der, eine große Luftgeschwindig­ keit erzeugenden Lüfterwirkung der umlaufenden Bremsgehäusever­ rippung in Temperaturbereichen, bei denen sie thermisch nicht überlastet werden.With full-pad disc brakes with circumferential, outside tilting The brake housing becomes the major part of the braking heat dissipated by convection. This heat transfer increases with increasing relative speed of the cooling air. That's why have full pad disc brakes especially when driving in chains proven witnesses, where they are on the, against the chains drive wheels strongly geared revolving, drive shafts are arranged. As a result of the then reduced Braking torque can be measured relatively small and light become and remain because of that, a great air speed speed-generating fan effect of the rotating brake housing Ripping in temperature ranges where they are not thermally be overloaded.

Für Antriebsachsen sind bereits Scheibenbremsenanordnungen vorge­ schlagen worden (DE-AS 22 31 259), bei denen das Fahrzeugrad über ein Planetengetriebe angetrieben ist und die Vollbelagscheiben­ bremse mit dem Antriebsteil der Achse verbunden ist. In diesem Fall dient das Antriebsvorgelege dazu, das von der Bremse aufge­ brachte Moment übersetzt in das Rad zu leiten.Disc brake arrangements are already provided for drive axles been hit (DE-AS 22 31 259), in which the vehicle wheel over a planetary gear is driven and the full lining discs brake is connected to the drive part of the axis. In this In this case, the drive gear is used by the brake brought moment to translate into the wheel.

Die Erfindung hat sich zur Aufgabe gesetzt, nichtangetriebene Rä­ der von schweren Radfahrzeugen mit übersetzt laufenden Bremsen auszurüsten. Diese Aufgabe wird durch die kennzeichnenden Merk­ male des Patentanspruchs gelöst. The invention has set itself the task of non-powered Ra that of heavy wheeled vehicles with brakes running in gear equip. This task is characterized by the characteristic male solved the claim.  

In der Abbildung ist ein Ausführungsbeispiel der Erfindung wiedergegeben. Sie zeigt den Längsschnitt durch das Vorder­ rad eines schweren Erdbewegungsfahrzeuges, bei dem die Brem­ se, von der Nabe angetrieben, mit höherer Drehzahl als letz­ tere umläuft.In the figure is an embodiment of the invention reproduced. It shows the longitudinal section through the front wheel of a heavy earth moving vehicle in which the brake se, driven by the hub, at a higher speed than last tere rotates.

In der Abbildung ist mit 1 das Vorderrad eines Erdbewe­ gungsfahrzeugs gekennzeichnet, dessen Radkörper 1 1 über Ke­ gelrollenlager 2 auf dem Achsschenkel 3 gelagert ist. Der Radkörper 1 1 ist mit einem innenverzahnten Zahnkranz 4 ver­ schraubt, in den das Ritzel 5 1, welches mit dem Überset­ zungsrad 5 2 eine Einheit bildet, eingreift. Die Doppelzahn­ räder 5 1/52 sind am Bremsträger 6 auf Zapfen 7 gelagert.In the figure, the front wheel of an earth moving vehicle is identified by 1, the wheel body 1 1 of which is mounted on the steering knuckle 3 via the gel roller bearing 2 . The wheel body 1 1 is screwed ver with an internally toothed ring gear 4 , in which the pinion 5 1 , which forms a unit with the transmission wheel 5 2 , engages. The double gears 5 1/5 2 are mounted on pins 7 on the brake carrier. 6

Der Bremsträger 6 ist mit dem hohl gebohrten Achsschenkel 3 verschraubt. Beide tragen auf den Lagern 8 und 9 die über­ setzt laufende Bremswelle 10, in dessen Ritzel 10 1 das Zahn­ rad 5 2 eingreift. Die Abdichtung der Nabe und der Bremswelle übernehmen die drei Wellendichtungen 11, 12 und 13. In Nuten 6 1 des Bremsträgers 6 sitzen axial frei beweglich die beiden mit Sinterkeramikbelägen ausgerüsteten Bremsscheiben 14 1 und 142. Zwischen den Bremsscheiben ist die Druckluftzuspann­ vorrichtung 15, ebenfalls axial frei beweglich, gelagert.The brake carrier 6 is screwed to the hollow drilled steering knuckle 3 . Both bear on the bearings 8 and 9, the over-running brake shaft 10 , in whose pinion 10 1 the toothed wheel 5 2 engages. The three shaft seals 11 , 12 and 13 seal the hub and the brake shaft. The two brake disks 14 1 and 14 2 equipped with sintered ceramic coverings are seated in grooves 6 1 of the brake carrier 6 in an axially freely movable manner. Between the brake discs, the compressed air application device 15 , also axially freely movable, is mounted.

Die durch das Fußbremsventil geregelte Betätigungsdruckluft wird der Zuspannvorrichtung über den Schlauch 16, die Boh­ rungen 17 und 18 in der Nabe, Bohrungen 19, 20 und 21 im Bremsträger zugeführt. Zu diesem Zweck weist die Zuspannvor­ richtung einen nach innen ragenden, als Ringstützen mit Boh­ rung 15 2 ausgerüsteten Fortsatz 15 1 auf. In der Bohrung 15 2 sitzt, befestigt durch die Hutmutter 23, der Hohlbolzen 22, durch dessen Längs- und Querbohrungen die Luft in die Zu­ spannvorrichtung gelangt. Der Hohlbolzen 22 ist durch einen Kolbenring 24 in der Bohrung 21 abgedichtet. Die Zuspann­ vorrichtung 15 selbst ist in Fig. 2 vergrößert wiedergegeben. Dort sind die Bezugszeichen der Einzelteile vermerkt.The actuating compressed air regulated by the foot brake valve is fed to the application device via the hose 16 , the holes 17 and 18 in the hub, bores 19 , 20 and 21 in the brake carrier. For this purpose, the Zuspannvor direction has an inwardly projecting, as ring supports with Boh tion 15 2 equipped extension 15 1 . Seated in the bore 15 2 , fastened by the cap nut 23 , the hollow bolt 22 , through the longitudinal and transverse bores of which the air enters the clamping device. The hollow pin 22 is sealed by a piston ring 24 in the bore 21 . The application device 15 itself is shown enlarged in Fig. 2. The reference numbers of the individual parts are noted there.

Mit der Bremswelle 10 ist das radial verrippte Bremsgehäuse 25 und mit letzterem über die Schrauben 26 der Bremsdeckel 27 verbunden. Angetrieben durch den mit der Radnabe ver­ schraubten Zahnkranz 4, Zahnräder 5 1/52 und Ritzel 10 1 läuft das Bremsgehäuse 25/27 mit mehrfacher Drehzahl des Rades um. Dadurch wird einerseits das von ihnen aufgenommene Bremsmoment entsprechend der Übersetzung des Vorgeleges ver­ größert auf das Rad übertragen und andererseits die von den radialen Rippen des Bremsgehäuses erzeugte Luftbewegung ver­ stärkt.The radially ribbed brake housing 25 is connected to the brake shaft 10 and to the latter via the screws 26 of the brake cover 27 . Driven by the ver with the wheel hub screwed ring gear 4, gears 5 1/5 2 and pinion 10, the brake housing 1 25/27 passes around the wheel with multiple speed. On the one hand, this increases the braking torque recorded by them in accordance with the ratio of the countershaft on the wheel, and on the other hand reinforces the air movement generated by the radial ribs of the brake housing.

Zum Auswechseln der Verschleißteile werden die Befestigungs­ schrauben an der Bremswelle 10 entfernt und die gesamte Bremse axial vom Bremsträger 6 abgezogen. Dann kann die abgenommene Bremse zerlegt und die Verschleißteile können ausgewechselt werden. Bei sehr großen Bremsen kann auch nach Lösen der Befestigungsschrauben an der Bremswelle 10 die Muttern der Schrauben 26 gelöst und das Bremsgehäuse 25 von der Brems­ welle 10 abgenommen werden. Dann kann nacheinander die Brems­ scheibe 14 1, die Zuspanneinheit 15 und die Bremsscheibe 14 2 abgezogen werden. Das Zusammensetzen der Bremse erfolgt in umgekehrter Reihenfolge.To replace the wearing parts, the fastening screws on the brake shaft 10 are removed and the entire brake is removed axially from the brake carrier 6 . Then the removed brake can be dismantled and the wearing parts can be replaced. For very large brakes, the nuts of the screws can be loosened 26 after loosening the mounting screws in the brake shaft 10 and the brake housing 25 of the brake shaft to be removed 10th Then the brake disc 14 1 , the application unit 15 and the brake disc 14 2 can be removed one after the other. The brake is assembled in the reverse order.

Die Zuspannvorrichtung 15 besteht aus dem Ringzylinder 15 3, in welchem, durch Kolbenringe 15 4 und 15 5 abgedichtet, der Ringkolben 15 6 axial beweglich gelagert ist. Ringkolben und Ringzylinder bilden den Druckraum 15 7, dem zum Bremsen über die Bohrung 15 2 Druckluft zugeführt wird. Beim Bremsvorgang überträgt der Ringzylinder 15 3 seine Spreizkraft über runde Vorsprünge 15 8 auf die Bremsscheibe 14 1 und der Kolben 15 6 über gegenüberliegende, am Umfang angeordnete zylindrische Fortsätze 15 9 dieselbe Kraft auf die Bremsscheibe 14 2. Der Ringzylinder 15 3 besitzt einen ringförmigen Deckel 15 10, der durch Sprengringe 15 11 gehalten und durch Kolbenringe 15 12 und 1513 abgedichtet ist. Die Abdichtung der Fortsätze 15 9 im Ringdeckel 15 10 erfolgt durch kleine Kolbenringe 15 14. Die Rückstellkraft nach der Bremsung erzeugen Druckfedern 15 15.The application device 15 consists of the ring cylinder 15 3 , in which, sealed by piston rings 15 4 and 15 5 , the ring piston 15 6 is axially movable. The annular piston and the annular cylinder form the pressure chamber 15 7 , to which compressed air is supplied for braking via the bore 15 2 . When braking, the ring cylinder 15 3 transmits its spreading force via round projections 15 8 to the brake disc 14 1 and the piston 15 6 via opposite cylindrical projections 15 9 arranged on the circumference to the same force on the brake disc 14 2 . The ring 3 has an annular cylinder 15 cover 15 10 which is held in place by snap rings 15 and 11 sealed by piston rings 15 12 and 15. 13 The extensions 15 9 in the ring cover 15 10 are sealed by small piston rings 15 14 . The restoring force after braking is generated by compression springs 15 15 .
