Diese völlig neuartige Anordnung und Gestaltung hat den Vorteil, dass aufwendige Schaltvorgänge wegfallen.This completely new arrangement and design has the advantage that expensive switching operations are eliminated.
Der Erfindung liegt der Schwerpunkt zugrunde, das Planetengetriebe so zu verändern, dass es signifikant kostengünstig ist und einen deutlichen höheren Schaltkomfort bietet als ein herkömmlichen Schaltgetriebe.The invention is based on the emphasis to change the planetary gear so that it is significantly inexpensive and offers a significantly higher shifting comfort than a conventional manual transmission.
Zum Auswählen der jeweiligen Übersetzungsverhältnisses dienen dreiTo select the respective gear ratio serve three
Planetenradsätze, deren Anzahl der Räder und deren Anordnung von den angestrebten Übersetzungsverhältnissen abhängen.Planetary gear sets whose number of wheels and their arrangement depend on the desired gear ratios.
Alle Zahnräder sind ständig im Eingriff und mittels betätigter Bremse werden die einzelnen Hohlräder des Planetengetriebes festgehalten oder freigegeben, wodurchMie Planetenträger und Sonneräder entsprechend rotieren.All the gears are constantly engaged and by means of the brake actuated the individual ring gears of the planetary gear are held or released, whereby the planetary carrier and sun gears rotate accordingly.
Die Bremsen können mechanisch, hydraulisch oder elektromechanisch mit elektronischer Überwachung betätigt werden.The brakes can be operated mechanically, hydraulically or electromechanically with electronic monitoring.
Für die Bremsen können zum Einsatz kommen:For the brakes can be used:
Band-, Mehrscheiben-, Lamellenbremsen, elektromagnetische oder retardierende Bremsen.Belt, multi-disc, multi-disc brakes, electromagnetic or retarding brakes.
Sie sind auch untereinender kombinierbar.They are also combinable.
Es sind aber auch andere Bremsarten denkbar, ohne den Rahmen der Erfindung zu verlassen.But there are also other brake types conceivable without departing from the scope of the invention.
Je nach Anforderung kann auf der Antriebsseite ein hydraulischer Drehmomentwandler vorgeschaltet werden.Depending on requirements, a hydraulic torque converter can be connected upstream on the drive side.
