Description
Die Erfindung betrifft einen Riementrieb nach dem Oberbegriff von Anspruch 1 und ein Verfahren zum Steuern eines solchen Riementriebs. Der Riementrieb weist einen Treibriemen auf, durch den eine Motorkurbelwelle und ein Starter-Generator miteinander verbunden sind, und der durch eine Spannvorrichtung mit der erforderlichen Riemenspannkraft versorgt wird.The Invention relates to a belt drive according to the preamble of claim 1 and a method for controlling such a belt drive. The Belt drive has a drive belt through which an engine crankshaft and a starter generator are connected to each other, and by a tensioning device is supplied with the required belt tensioning force becomes.
Aus der betrieblichen Praxis ist ein Riementrieb mit zwei Spannrollen bekannt, von denen je eine in dem Riementrum vor und nach dem Starter-Generator sitzt. Die beiden Spannrollen sind mit Hebeln verbunden. Nachteilig sind vor allem der benötigte Bauraum und die erforderliche hohe Vorspannung.Out In practice, a belt drive with two tensioners is used known, one each in the belt drum before and after the starter generator sitting. The two tension rollers are connected with levers. adversely are above all the space required and the high preload required.
Der Erfindung liegt die Aufgabe zu Grunde, einen Riementrieb der eingangs genannten Art zu schaffen, der möglichst wenig Platz in dem Motorraum eines Kraftfahrzeugs benötigt. Außerdem soll er jederzeit eine ausreichend hohe Vorspannkraft für den Treibriemen aufbringen.The The invention is based on the object of a belt drive of the beginning to create the type mentioned, if possible takes up little space in the engine compartment of a motor vehicle. He should also Apply a sufficiently high pretensioning force for the drive belt at all times.
Diese Aufgabe wird erfindungsgemäß durch den Treibriemen nach Anspruch 1 und das Verfahren nach Anspruch 8 gelöst. Die Spannvorrichtung weist eine Spannrolle auf, die durch einen Aktuator gegen den Antriebsriemen gedrückt wird. Der Aktuator ist mit einer elektronischen Steuerung versehen, durch die die Riemenspannkraft dosiert und zeitlich gesteuert wird. Die Spannrolle wird durch Federkraft gegen den Antriebsriemen gedrückt, und in vorgegebenen Fahrsituationen des Kraftfahrzeugs wird die Spannrolle zusätzlich durch den Aktuator gegen den Antriebsriemen gedrückt. Der Aktuator kann hydraulisch, elektrisch oder elektro-hydraulisch betätigt werden.This The object is achieved by the Driving belt according to claim 1 and the method of claim 8 solved. The Tensioning device has a tensioning roller which is actuated by an actuator pressed against the drive belt becomes. The actuator is equipped with an electronic control through which the belt tensioning force is metered and timed. The tension pulley is pressed against the drive belt by spring force, and in predetermined driving situations of the motor vehicle, the tension pulley additionally pressed against the drive belt by the actuator. The actuator can be hydraulic, be operated electrically or electro-hydraulically.
Zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen niedergelegt.Appropriate further training the invention are laid down in the subclaims.
Die Vorteile der Erfindung liegen insbesondere darin, dass eine hohe Vorspannkraft nur dann auf den Treibriemen aufgebracht wird, wenn ein hohes Drehmoment übertragen werden muss. Das ist insbesondere beim Anlassen oder Starten des Motors erforderlich. Damit werden Verluste im Antrieb und ein hoher Verschleiß vermieden, die sich bei der üblichen ständigen hohen Vorspannkraft ergeben.The Advantages of the invention are in particular that a high Preload is only applied to the drive belt if transmit a high torque must become. This is especially true when starting or starting the Motor required. This increases losses in the drive and a high one Avoided wear, which is the usual permanent result in high preload.
