Abstract

The invention relates to a brake for heavy vehicles, the wheel hub of which is driven by a hydraulic motor, the brake acting on the drive part. In order to provide a brake for heavy vehicles which is not subjected to damage caused by dirt, and in which neither the braking forces influence the transmission part or engine part nor the brake is influenced by defective transmission parts or engine parts, it is proposed that it be designed as a multiple-disc brake which can be hydraulically lifted counter to spring force, the outer discs (2) being connected to the fixed stub-axle flange (4) of the wheel drive. <IMAGE>

Description

Die Erfindung betrifft eine Bremse fUr schwere Fahrzeuge,The invention relates to a brake for heavy vehicles,

deren Radnabe von einem Hydraulikmotor angetrieben wird, wobei die Bremse auf den Antriebsteil wirkt.whose wheel hub is driven by a hydraulic motor, the Brake acts on the drive part.

Aus dem Firmenprospekt der Lohmann & Stolterfoht GmbH ist ein Radmotor bekannt, bei dem der Hydraulikmotor cins Sonnenrad einer ersten Planetenstufe antreibt, deren Planetensteg mit dem Sonnenrad einer zweiten Planetenstufe verbunden ist. Die radnabe bildet das Hohlrad beider Planetenstufen. Mit der Radnabe ist eine Trommel verbunden, auf die eine übliche Trommelbremse wirkt.From the company brochure of Lohmann & Stolterfoht GmbH is a Wheel motor known in which the hydraulic motor cins sun gear of a first planetary stage drives whose planetary web is connected to the sun gear of a second planetary stage is. The wheel hub forms the ring gear of both planetary stages. With the wheel hub is one Connected drum, on which a conventional drum brake acts.

Bei einer derartigen Anordnung besteht die MölJlichkeit, daß die Funktion der Bremse durch ;iußere Einflüsse (Wasser, Schmutz, Sand) bf?eintr.ichtig-t wird.With such an arrangement there is the possibility that the function the brake by; external influences (water, dirt, sand) bf?

Aufgabe der Erfindung ist es daher eine Bremse für schwere Fahrzeuge zu schaffen, die keiner Beeinträchtigung durch Verschmutzung unterliegt und bei der die Bremskräfte weder das Getriebe- bzw. Motorteil beeinflussen noch die Bremse durch defekte Getriebe- bzw. Motortei]e beeinflußt wird.The object of the invention is therefore a brake for heavy vehicles to create that is not subject to impairment by pollution and at which the braking forces neither affect the gear or motor part nor the brake is influenced by defective gear or motor parts.

Gelöst wird diese Aufgabe erfindungsgemäß durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale.This object is achieved according to the invention by means of the characteristics of claim 1 specified features.

Eine Ausgestaltung ergibt sich aus dem Unteranspruch.One embodiment results from the subclaim.

Die erfindungsgemäße Bremse weist eince große Zahl von Vorteilen gegenüber dem Stand der Technik auf.The brake according to the invention has a large number of advantages over the state of the art.

Die Bremskräfte werden direkt am zu bremsenden Antriebsteil wirksam, so daß negative Beeinflussungen im Sinne der gestellten Aufgabe vermieden werden.The braking forces take effect directly on the drive part to be braked, so that negative influences in terms of the task at hand are avoided.

Die total gekoppelte Auszührung schiitzt vor Verschmutzungen und ermöglicht den Lamellenverschleiß gering zu halten, weil die Lamellenbrernse in öl laufen kann.The totally coupled discharge protects against dirt and enables To keep the disk wear low, because the disk brake can run in oil.

Bei einem hydraulischen Druckausfall erfolgt ein automatisches Abbremsen, weil die Lamellen gegen die Federkraft hydraulisch gelüftet werden.In the event of a hydraulic pressure failure, automatic braking takes place, because the slats are hydraulically lifted against the spring force.

Schließlich ergeben sich Vorteile durcb die Verwendung einer Tellerfeder als Federelement. Bei Lamellenbremsen werden vielfach Schraubenfedern benutzt. In Abhängigkeit von der Federkraft ändert sich das Bauvolumen, weil starker Federn mehr Raum einnehmen.Finally, there are advantages to using a disc spring as a spring element. In multi-disc brakes, coil springs are often used. In Depending on the spring force, the construction volume changes because of the stronger springs take up more space.

Durch Verwendung einer Tellerfeder konnte das Gesamtvolumen der Bremsanordnung wesentlich verringert werden und darüberhinaus ]'ißt sich mit einer Tellerfeder ein nahezu konstantes Bremsmoment über einen großen Toleranzbereich erreichen.By using a disc spring, the total volume of the brake assembly can be significantly reduced and moreover] 'eats itself with a plate spring achieve an almost constant braking torque over a large tolerance range.

Die erfindungsgemäße Bremse soll nachfolgend anhand der Zeichnung erläutert werden, wobei die Figur einen Ltingsschnitt durch die Bremse zeigt, während die Ubrigen Teile des Antriebes nur skizziert sind.The brake according to the invention is intended below with reference to the drawing be explained, the figure showing a Ltingsschnitt by the brake while the other parts of the drive are only sketched.

Der Radantrieb weist einen Motor 1 auf, ester auf das Sonnenrad beispielsweise eines Planetengetribes (nicht dargestellt) wirkt. Die Außenlamellen 2 sind über den LRmellenträger 3 mit dem Achsschenkelflansch 4 verbunden, während die Innenlamellen 5 am Hohlrad 6 (Radnabe) des Getriebes 'S sitzen. Ein hydraulisch beaufschlagter (lüftbarer) Druckkolben A wirkt zusammen mit einer Tellerfeder 9 auf die Lamellenbremse ein. Betätigt wird die Bremse durch das Hyclraulikmedium d.h. der hydraulische Druck bewegt den Druckkolben 8 (in der Figur) nach links gegen die Kraft der Feder 9 und lüftet auf diese Weise die Lamellen. Bei Ausfall des Druckes ist der Antrieb automatisch gebremst. The wheel drive has a motor 1, which acts on the sun gear, for example of a planetary gear (not shown). The outer disks 2 are connected to the steering knuckle flange 4 via the L-shaft carrier 3, while the inner disks 5 are seated on the ring gear 6 (wheel hub) of the transmission. A hydraulically acted upon (releasable) pressure piston A acts together with a plate spring 9 on the multi-disc brake. The brake is actuated by the hydraulic medium, ie the hydraulic pressure moves the pressure piston 8 (in the figure) to the left against the force of the spring 9 and in this way lifts the lamellae. If the pressure fails, the drive is automatically braked.
