Automatische Schaltvorrichtung für Differentialsperren bei RadfahrzeugenAutomatic switching device for differential locks in wheeled vehicles

Gegenstand derErfindung ist eine automatische Schaltvorrichtung für Differentialsperren bei Radfahrzeugen mittels eines elektrischen, hydraulischen oder pneumatischen Endschalters. -..'.' The subject of the invention is an automatic switching device for differential locks in wheeled vehicles by means of an electrical, hydraulic or pneumatic limit switch. - .. '.'

Bei den bekannten Sperrsystemen unterscheidet man zwei Arten, einmal Achsen mit Sperrdifferentialen, die einen bestimmten eingestellten Sperrwert haben, zum anderen Achse'n mit unter Last schaltbaren hydraulischen Differentialsperren. Im ersten Fall sind die Sperren in den Achsen eingebaut und wirken bei Drehmomentunterschieden an einer Achse selbsttätig. Allerdings erlaubt dieses System keine völlige Sperrung des Differentials, da bei Kurvenfahrt die Differentialwirkung erhalten bleiben muß.In the known locking systems, a distinction is made between two types, one axles with locking differentials that have a specific set locking value, on the other hand with hydraulic differential locks that can be switched under load. In the first case, the locks are built into the axles and work automatically in the event of torque differences on one axis. However, allowed this system does not completely lock the differential as it is when cornering the differential effect must be preserved.

Im anderen Fall wird die Sperre vom Fahrer selbst von Hand betätigt. Diese Anordnung läßt nun zwar eine volle Ausnutzung des Sperrwertes zu, da die Sperrwirkung bei Kurvenfahrt vom Fahrer gänzlich aufgehoben werden kann und nunmehr die Differentiale der Achsen wirken, jedoch wird der Fahrer bei dieser Bauweise mit einer zusätzlichen Hebelbedienung belastet. Außerdem erfolgt die Betätigung der Sperre zumeist erst beim Durchrutschen der Räder, was erhöhten Verschleiß zufolge hat.In the other case, the lock is operated manually by the driver himself. These Arrangement now allows full utilization of the locking value, since the Locking effect when cornering can be completely canceled by the driver and now the differentials of the axles are working, but the driver is at this construction is burdened with an additional lever operation. In addition, the lock is usually only activated when the wheels slip, which has resulted in increased wear and tear.

Um die aufgeführten Nachteile zu beseitigen, wurde erfindungsgemäß eine Konstruktion geschaffen, bei der ein elektrischer, hydraulischer oder pneumatischer Endschalter über das Lenkgestänge so betätigt wird, daß bei entsprechendem Radeinschlag, etwa in Kurvenfahrt, die Sperrwirkung aufgehoben wird. Vorzugsweise wird jedoch im Fahrerhaus noch eine zusätzliche Handbetätigung für den Endschalter angebracht, so daß der Fahrer die Möglichkeit hat, auch bei Kurvenfahrten nötigenfalls die Sperre zu betätigen, so bei Kurvenfahrten auf ungünstigen Bodenverhältnissen. Durch diese Konstruktion ist somit eine sinnvolle Betätigung der Sperre ermöglicht worden. Beispielsweise kann beim Laden und Schürfen die Maschine mit gesperrten Achsen arbeiten und die Vorschubkraft optimal auf den Boden bringen, während andererseits bei Kurvenfahrt die Differentiale der Achsen zur Wirkung- kommen. Ferner bietet die Bauweise den Vorteil, daß die Sperre selten unter Last geschaltet wird, wodurch eine höhere Lebensdauer gewährleistet ist. Ein Ausführungsbeispiel der Erfindung ist in beiliegender Zeichnung dargestellt. In order to eliminate the disadvantages listed, according to the invention was a Construction created in which an electric, hydraulic or pneumatic Limit switch is operated via the steering linkage so that the locking effect is canceled when the wheel is turned accordingly, for example when cornering will. However, an additional manual operation is preferred in the driver's cab for the limit switch attached, giving the driver the option has to activate the lock if necessary, even when cornering, so at Cornering on unfavorable ground conditions. Through this construction a meaningful actuation of the lock has thus been made possible. For example the machine can work with locked axes when loading and mining and bring the feed force optimally to the ground, while on the other hand the differentials of the axles come into effect when cornering. The design also offers the advantage that the lock is seldom switched under load which ensures a longer service life. An embodiment of the invention is shown in the accompanying drawing.

Automatische Schaltvorrichtung für Differentialsperren bei RädfahrzeugenAutomatic switching device for differential locks in wheeled vehicles

Ein fest am Rahmen eines Radfahrzeuges montierter Endschalter (T) berührt mit seinem Schaltknopf (2) eine Oberfläche (5) eines fest am Lenkhebel (5) des Radfahrzeuges angebrachten Verbindungsstückes (4), vorzugsweise einer Nocke, die so gestaltet ist, daß der Schaltpünkt der Sperre beliebig über den ganzen Lerikbereich (et) verstellt werden kann. Je nach Lenkeinschlag wird der Lenkhebel (5) und mit ihm das Verbindungsstück (4) entweder in Richtung (a) oder in Richtung (b) bewegt, so daß der Schältknopf (2) des Endschalters (l) auf der Oberfläche (3) des Verbindungsstückes (4) in Gegenrichtung zur Bewegung des Lenkhebels (5) entlang gleitet. Sobald nun der Lenkeinschlag so groß ist, daß der Schaltknopf (2) sich außerhalb des festgelegten Sehaltpunktes der Sperre befindet, wird die Wirkung der Differenalsperre aufgehoben. :A limit switch (T) fixed on the frame of a wheeled vehicle is touched with its switch button (2) a surface (5) of a fixed on the steering lever (5) of the wheeled vehicle attached connecting piece (4), preferably one Cam, which is designed so that the switching point of the lock over the whole reading range (et) can be adjusted. Depending on the steering angle the steering lever (5) and with it the connecting piece (4) is moved either in direction (a) or in direction (b), so that the switch button (2) of the Limit switch (l) slides along on the surface (3) of the connecting piece (4) in the opposite direction to the movement of the steering lever (5). As soon as the The steering angle is so large that the switch button (2) is outside the specified Sehaltpunktes of the lock is, the effect of the differential lock is canceled. :
