Abstract
Description
Gebiet der ErfindungField of the invention
Die Erfindung bezieht sich auf das Gebiet von Kupplungen mit Drehmomentbegrenzungsfunktion.The invention relates to the field of clutches with torque limiting function.
Hintergrund der ErfindungBackground of the invention
Kraftfahrzeuge verwenden zum Anlassen des Motors beim Starten Startermotoren. Bei einem Startermotor wird der Antrieb über eine Freilaufkupplung übertragen. Die Freilaufkupplung ist zwischen dem Startermotor und dem Ritzel zum Eingriff mit dem Motorzahnkranz positioniert. Die Funktion der Freilaufkupplung besteht in der Übertragung des Antriebs auf das Ritzel, wenn der Startermotor die Antriebswelle antreibt, und dem Ausrücken des Ritzels von der Antriebswelle, sobald das Ritzel nach dem Anspringen des Motors beginnt, sich mit hohen Drehzahlen zu drehen. Die zentralen Komponenten einer Freilaufkupplung umfassen eine Schale mit zwischen einem inneren Ring und einem Ritzel über den Umfang angeordneten Rollen, wobei die Rollen entlang einem eingegrenzten Raum durch Federhalterung frei beweglich sind. Die Rollen stellen einen Reibkontakt zwischen dem inneren Ring und dem Ritzel her und übertragen somit den Antrieb vom inneren Ring auf das Ritzel und weiter auf den Motor. Sobald der Motor beginnt zu beschleunigen, ist das Ritzel nicht in der Lage, der Motordrehzahl nachzukommen und beginnt, zu schnell zu laufen, wenn der Startermotor unter abnormaler Last, während Zurückstoßen des Motors oder wenn das Fahrzeug gestartet wird, ohne dass sich das Getriebe in der Neutralstellung befindet, anlassen muss. Demzufolge erfährt das Ritzel ein sehr hohes Drehmoment. Dieses hohe Drehmoment führt bei Rückübertragung auf den Startermotor über den inneren Ring zur Beschädigung der Komponenten des Startermotors. Darüber hinaus ist das vom Ritzel erfahrene Drehmoment hoch genug, um die Rollen innerhalb des begrenzten Raums zu zerbrechen, was zur Beschädigung der Freilaufkupplung führt.Motor vehicles use starter motors to start the engine when starting. In a starter motor, the drive is transmitted via an overrunning clutch. The one-way clutch is positioned between the starter motor and the pinion for engagement with the motor sprocket. The function of the one-way clutch is to transfer the drive to the pinion when the starter motor drives the drive shaft and disengage the pinion from the drive shaft as soon as the pinion starts to rotate at high speeds after the engine starts. The central components of an overrunning clutch comprise a shell having rollers disposed circumferentially between an inner ring and a pinion, the rollers being freely movable along a confined space by spring support. The rollers make a frictional contact between the inner ring and the pinion and thus transmit the drive from the inner ring to the pinion and further to the motor. As soon as the engine begins to accelerate, the pinion is unable to meet the engine speed and starts to run too fast when the starter motor is under abnormal load, while the engine is knocking back or when the vehicle is started without the gearbox in the neutral position, must start. As a result, the pinion experiences a very high torque. This high torque leads to damage to the components of the starter motor when retransferred to the starter motor via the inner ring. In addition, the torque experienced by the pinion is high enough to break the rollers within the limited space, resulting in damage to the one-way clutch.
In der
Somit besteht ein Bedarf, die Komponenten der Freilaufkupplung vor hohen Motorlasten wie oben erwähnt zu schützen. Des Weiteren besteht auch ein Bedarf an einer Kupplung, die eine Überlastung des Startermotors verhindert und den Zahnkranz im Schwungrad durch Begrenzung des an den Startermotor angelegten Drehmoments schützt. Bei herkömmlichen Kupplungen ist eine Verhinderung der Beschädigung der Komponenten der Kupplung nicht möglich, was zu einer verkürzten Lebensdauer der Kupplungskomponenten und des Zahnkranzes im Schwungrad führt.Thus, there is a need to protect the components of the overrunning clutch from high engine loads as mentioned above. Furthermore, there is also a need for a clutch that prevents overloading the starter motor and protects the ring gear in the flywheel by limiting the torque applied to the starter motor. In conventional clutches, it is not possible to prevent the damage of the components of the clutch, resulting in a shortened life of the clutch components and the sprocket in the flywheel.
Vorteile der ErfindungAdvantages of the invention
Der Vorteil der vorliegenden Erfindung gemäß dem unabhängigen Anspruch besteht in der Verbesserung der Lebensdauer von in einer Kupplung verwendeten Rollen, indem eine Drehmomentübertragung vom Motor zum Startermotor über die Kupplung verhindert wird. Ein weiterer Vorteil der Erfindung besteht im Schutz des Startermotors und des Zahnkranzes im Schwungrad vor Motorüberlast während des Anlassens, wodurch die Kupplungskomponenten vor Beschädigung geschützt werden.The advantage of the present invention according to the independent claim is to improve the life of rollers used in a clutch by preventing torque transmission from the engine to the starter motor via the clutch. Another advantage of the invention is protection of the starter motor and sprocket in the flywheel from engine overload during cranking, thereby protecting the clutch components from damage.
