Abstract
Description
Die Erfindung betrifft eine Portalachse nach der im Oberbegriff von Anspruch 1 näher definierten Art.The The invention relates to a gantry axis according to the preamble of Claim 1 closer defined type.
Portalachsen für niederflurige Fahrzeuge, insbesondere für Nahverkehrsomnibusse, werden im Omnibus eingesetzt, um einen ausreichend breiten und tiefen Gang im Omnibus zu schaffen und hierbei für das Fahrzeug ausreichende Bodenfreiheit zu gewährleisten.portal axles for low-floor Vehicles, especially for Local buses, are used in buses to get a sufficient wide and deep gear in the bus to create and this for the vehicle to ensure sufficient ground clearance.
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, das Einstiegsniveau des Omnibusses noch zu verringern und somit den Gang noch weiter abzusenken, ohne die Bodenfreiheit des Fahrzeugs negativ zu beeinflussen.Of the present invention is based on the object, the entry level of the bus to reduce and thus lower the gear even further, without adversely affecting the ground clearance of the vehicle.
Die Aufgabe wird mit einer, auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisenden, gattungsgemäßen Portalachse gelöst.The Task is with a, even the characterizing features of the main claim having, generic portal axis solved.
Erfindungsgemäß weist die Portalachse ein Ausgleichsgetriebe auf, dessen Ausgleichsgehäuse mit einem Kegelrad-Schraubengetriebe, einem sogenannten Hypoidgetriebe, verbunden ist. Hierbei besteht die Möglichkeit, das Tellerrad des Hypoidgetriebes lösbar mit dem Gehäuse des Ausgleichsge triebes zu verbinden oder es mit diesem zu verschweißen oder einstückig mit diesem auszubilden. Die Drehachse des Antriebsritzels des Kegelrad-Schraubengetriebes weist einen Winkel zur Drehachse des Tellerrades des Kegelrad-Schraubengetriebes auf, welcher zwischen nahezu 80° und 90° angeordnet ist. Dies ermöglicht, die Antriebsmaschine des Fahrzeugs und dessen Untersetzungsgetriebe variabel im Fahrzeug anzuordnen.According to the invention the portal axle on a differential gear, whose balance housing with a bevel gear screw, a so-called hypoid gear, connected is. There is the possibility of the crown of the Hypoid gear detachable with the housing the Ausgleichsge gear to connect or to weld it with this or one piece to train with this. The axis of rotation of the drive pinion of the bevel gear screw drive has an angle to the axis of rotation of the ring gear of the bevel gear screw drive on which between almost 80 ° and 90 ° is arranged. This makes possible, the engine of the vehicle and its reduction gear to arrange variably in the vehicle.
In einer weiteren Ausgestaltungsform ist die Drehachse des Antriebsritzels des Kegelrad-Schraubengetriebes weiter entfernt zur Fahrbahnoberfläche angeordnet, als die Drehachse des Tellerrades des Kegelrad-Schraubengetriebes zur Fahrbahnoberfläche angeordnet ist. Dadurch wird der Beugewinkel der Gelenkwelle, welche das Untersetzungsgetriebe mit dem Antriebsritzel verbindet, verkleinert, was zu einer Erhöhung der Lebensdauer der Gelenkwelle führt. Das Kegelrad-Schraubengetriebe ist in einer weiteren Ausgestaltungsform geradverzahnt, schrägverzahnt, bogenverzahnt oder spiralverzahnt ausgeführt.In Another embodiment is the axis of rotation of the drive pinion the bevel gear drive further away from the road surface, as the axis of rotation of the ring gear of the bevel gear screw drive to the road surface is arranged. As a result, the flexion angle of the propeller shaft, which the reduction gear connects to the drive sprocket, downsized, what an increase the life of the PTO shaft leads. The bevel gear screw drive is in a further embodiment straight teeth, helical teeth, arcuate or spiral toothed executed.
Durch die Verwendung eines Kegelrad-Schraubengetriebes, eines sogenannten Hypoidgetriebes, schneiden sich die Drehachsen der Kegelräder nicht im Drehpunkt des Ausgleichsgetriebes, sondern kreuzen sich außerhalb dieses Punktes. Dadurch entstehen neben den Wälzbewegungen auch Gleitbewegungen, wodurch das Verzahnungsgeräusch erheblich minimiert wird und bei gleicher Baugröße des Kegelradgetriebes die Lebensdauer erhöht ist. Somit besteht bei gleicher benötigter Lebensdauer der Portalachse die Möglichkeit, das Tellerrad in seinem Durchmesser zu minimieren, welches durch seine radiale Erstreckung die Bodenfreiheit des Fahrzeugs beeinflußt, wodurch durch die Minimierung des Durchmessers des Tellerrades bei gleichbleibender Bodenfreiheit der Achsversatz im Portalgetriebe von der Antriebswelle, welche mit dem Ausgleichsgetriebe verbunden ist, zur Drehachse des Fahrzeugrades vergrößert wird. Durch diese Vergrößerung des Portalabstands kann die Achs brücke tiefer angeordnet werden, was sich auf die Anordnung des Gangs im Fahrzeug auswirkt, wodurch dieser tiefer angeordnet sein kann. Durch die Verwendung eines Hypoidgetriebes beim Ausgleichsgetriebe einer Portalachse besteht somit die Möglichkeit, die Einstiegshöhe des Fahrzeugs weiter zu verringern. Das Fahrzeug weist somit eine niedrigere Flurhöhe auf.By the use of a bevel gear drive, a so-called Hypoid gear, do not intersect the axes of rotation of the bevel gears in the fulcrum of the differential gear, but intersect outside of this point. As a result, in addition to the rolling movements and sliding movements, causing the gear noise is considerably minimized and the same size of the bevel gear Lifespan increased is. Thus, there is the same required lifetime of the portal axis the possibility, to minimize the ring gear in its diameter, which through its radial extent affects the ground clearance of the vehicle, thereby by minimizing the diameter of the ring gear at the same Ground clearance of the axial offset in the gantry gearbox from the drive shaft, which is connected to the differential, to the axis of rotation of the Vehicle wheel is increased. Due to this enlargement of the Gantry distance, the axle bridge deeper be arranged, reflecting the arrangement of the gear in the vehicle effect, which can be arranged deeper. By the Use of a hypoid gear in the differential gear of a portal axle Thus there is the possibility, the entry height of the vehicle continues to decrease. The vehicle thus has a lower floor height on.
