Abstract
Description
Die hier dargestellte Erfindung soll die Handkraft zur Betätigung der Kupplung wesentlich verringern und im Schiebebetrieb, bei Teillast/Lastwechseln und beim Bremsen das übertragbare Motormoment soweit begrenzen, dass das Hinterrad nicht zum Rutschen oder Springen kommt (sogenannte antihopping- oder slipper-Funktion).The Invention shown here is the hand force for actuating the Reduce coupling considerably and in overrunning mode, at partial load / load changes and when braking the transmittable Limit engine torque so far that the rear wheel is not slipping or jumping comes (so-called antihopping or slipper function).
Die Kräfte auf die Kupplungslamellen setzen sich dabei wie folgt zusammen:
- – eine über Druckfedern erzeugte Anpresskraft (Federkraft) „Ff”, die aber nur einen Teil des vollen Antriebsmoments übertragen kann, daher
- – mit geringer Handkraft „Fh” aufhebbar ist.
- – eine vorzugsweise hydraulisch erzeugte Zusatzkraft „Fz”, mit deren Hilfe das volle Antriebsmoment sicher übertragbar ist.
- - A pressure force generated by springs (spring force) "Ff", but only a part of the full drive torque can transmit, therefore
- - With little manual force "Fh" can be canceled.
- - A preferably hydraulically generated additional force "Fz", with the help of the full drive torque is safely transferable.
Die hydraulische Zusatzkraft „Fz” wird von einem Kolben auf die Kupplungslamellen kraftschlüssig übertragen. Der Kolben wird über ein Ventil angesteuert und vorzugsweise von der Schmierölpumpe des Motors versorgt. Das Ventil ist vorzugsweise als 3/2 Wege Ventil ausgeführt und elektrisch betätigt. Die Bauart des Ventils ist nicht entscheidend, dessen Darstellung ist symbolisch und dient zur Veranschaulichung. Die Betätigung kann entweder gesteuert (ein-aus) oder geregelt (proportional) über eine Rechner-/Steuereinheit erfolgen.The additional hydraulic power "Fz" is provided by a non-positively transmitted piston on the clutch plates. The piston is over Valve controlled and preferably by the lubricating oil pump of Motors supplied. The valve is preferably a 3/2 way valve accomplished and electrically operated. The Design of the valve is not critical, whose representation is symbolic and serves as an illustration. The operation can either controlled (on-off) or regulated (proportional) via a computer / control unit respectively.
Einflussparameter
für die
Steuerung/Regelung des Ventils können
hierbei sein:
Drosselklappenstellung, Motordrehzahl, Vorder-/Hinterraddrehzahl,
Saugrohrdruck, Bremsdruck, manueller Kupplungs-Betätigungsdruck,
Beschleunigungs- oder Neigungssensoren.Influence parameters for the control / regulation of the valve can be:
Throttle position, engine speed, front / rear wheel speed, intake manifold pressure, brake pressure, manual clutch actuation pressure, acceleration or tilt sensors.
Stand der Technik:State of the art:
Moderne Ein- und Zweizylinder-Sportmotorräder mit großem Hubraum haben aus Gewichtsgründen eine sehr kleine Motorschwungmasse und trotzdem ein hohes Motorbremsmoment, was zu schlechtem Gleichförmigkeitsgrad und hohen Drehmomentspitzen am Hinterrad führt. Zusammen mit der ausgeprägten dynamischen Achslastverschiebung bei Sportmotorrädern beim Bremsen/bei Lastwechseln kann dies zu kurzzeitig blockierendem und hüpfendem Hinterrad führen und ein erhebliches Sicherheitsrisiko mit Sturzgefahr darstellen.modern One- and two-cylinder sports motorcycles with large displacement have a weight reasons very small engine flywheel and still a high engine braking torque, what to bad degree of uniformity and high torque peaks on the rear wheel leads. Along with the pronounced dynamic Axle load shift on sports motorcycles during braking / load changes this can lead to short-term blocking and jumping rear wheel and represent a significant safety risk with danger of falling.
Es sind zahlreiche Lösungen bekannt, um im Fahrzustand Bremsen/Schubbetrieb die Anpresskraft auf die Fahrzeugkupplung soweit zu reduzieren, dass nur ein Teil des vorhandenen Bremsmoments von den Kupplungslamellen übertragen wird. Alle diese Lösungen zielen aber darauf ab, durch eine Gegenkraft die Anpresskraft auf die Kupplungslamellen zu reduzieren.It are numerous solutions known in the driving state brakes / push operation, the contact pressure to reduce the vehicle clutch so much that only a part of the existing braking torque transmitted by the clutch plates becomes. All these solutions But aim to counteract by a counter force on the contact force to reduce the clutch plates.
Neuheit:Novelty:
Die Neuheit der Vorrichtung besteht darin, dass nicht die hohe (normalerweise notwendige) Anpresskraft reduziert wird, sondern eine niedrige Anpresskraft bei Bedarf erhöht wird.The Novelty of the device is that not the high (usually necessary) contact pressure is reduced, but a low contact pressure increased if necessary becomes.
Dies hat den entscheidenden Vorteil, dass bei manueller Betätigung der Kupplung nur diese niedrige Anpresskraft durch die Handkraft des Fahrers überwunden werden muss. Hierdurch ergibt sich ein wesentlich leichteres Betätigen und damit automatisch eine Servowirkung der Kupplung.This has the decisive advantage that when manually operated Clutch only this low contact force by the hand force of the Driver overcome must become. This results in a much easier operation and thus automatically a servo effect of the clutch.
Funktionsbeschreibung:Function Description:
Die Funktion der Vorrichtung ist im wesentlichen anhand von 3 statischen Grundzuständen beschreibbar. Die Richtung der eingangs erwähnten Kräfte ist in den Zeichnungen dargestellt, ebenso die Ventilstellungen. Die dynamischen Übergänge zwischen diesen 3 Grundzuständen sind nicht Inhalt dieser Beschreibung und erfordern fahrzeugspezifische Festlegung und Erprobung.The Function of the device is essentially based on 3 static ground states writable. The direction of the forces mentioned above is shown in the drawings shown, as well as the valve positions. The dynamic transitions between these 3 basic states are not content of this description and require vehicle-specific specification and testing.
