Description
Die Erfindung betrifft eine Elektromotor-Getriebe-Anordnung für einen hybridischen oder rein elektrischen Kraftfahrzeugantriebsstrang, d. h. einen Antriebsstrang eines Kraftfahrzeuges, wie eines Pkws, Lkws, Busses oder sonstigen Nutzfahrzeuges, mit einem Elektromotor, wobei der Elektromotor einen gehäusefesten, gesamtheitlich ringförmig ausgebildeten Stator und einen radial innerhalb des Stators, relativ zu dem Stator verdrehbar gelagerten Rotor aufweist, sowie mit einem an den Rotor anschließenden / wirkend angekoppelten Getriebe. Des Weiteren betrifft die Erfindung eine Antriebseinheit mit dieser Elektromotor-Getriebe-Anordnung und zumindest mit einer Verbrennungskraftmaschine, die über eine Schalteinrichtung mit der Anordnung koppelbar ist.The invention relates to an electric motor-transmission arrangement for a hybrid or purely electric motor vehicle drive train, d. H. a drive train of a motor vehicle, such as a car, truck, bus or other commercial vehicle, with an electric motor, wherein the electric motor has a housing-fixed, entirely annular stator and a rotor mounted radially inside the stator, rotatable relative to the stator, and with a gear connected to / effectively coupled to the rotor. The invention also relates to a drive unit with this electric motor-transmission arrangement and at least with an internal combustion engine which can be coupled to the arrangement via a switching device.
Gattungsgemäße Antriebsanordnungen sind aus dem Stand der Technik bereits hinlänglich bekannt. Beispielsweise ist der Anmelderin interner Stand der Technik bekannt, der bereits als Deutsche Patentanmeldung beim Deutschen Patent- und Markenamt eingereicht worden ist, jedoch noch vor der Veröffentlichung steht. Dieser betrifft die Aktenzeichen 10 2019 131 956.0 mit dem Anmeldetag 26.11.2019 sowie 10 2019 130 829.1 mit dem Anmeldetag 15.11.2019. Hiermit sind Antriebssysteme und Betätigungsvorrichtungen zum Betätigen dieser Antriebssysteme offenbart.Generic drive arrangements are already sufficiently known from the prior art. For example, the applicant is aware of internal state of the art which has already been filed as a German patent application at the German Patent and Trademark Office, but is still about to be published. This concerns
Als prinzipieller Nachteil der aus dem Stand der Technik bekannten Anordnungen, die aus zumindest einem Elektromotor und einem Getriebe bestehen, ist insbesondere der relativ große axiale Bauraumbedarf zu nennen. Denn meist sind die Getriebe und der Elektromotor entlang einer Antriebsachse in Reihe hintereinander angeordnet.A fundamental disadvantage of the arrangements known from the prior art, which consist of at least one electric motor and a gear, is in particular the relatively large axial space requirement. This is because the gearbox and the electric motor are usually arranged in series one behind the other along a drive axis.
Es ist daher Aufgabe der vorliegenden Erfindung, diese aus dem Stand der Technik bekannten Nachteile zu beheben und insbesondere eine aus einem Elektromotor und einem Getriebe bestehende Anordnung zur Verfügung zu stellen, die hinsichtlich ihrer axialen Erstreckung deutlich kompakter ausgebildet ist.It is therefore the object of the present invention to remedy these disadvantages known from the prior art and, in particular, to provide an arrangement consisting of an electric motor and a gearbox, which is made significantly more compact with regard to its axial extension.
Dies wird erfindungsgemäß dadurch gelöst, dass das Getriebe zumindest teilweise in einem radialen Hohlraum des Rotors angeordnet ist, d.h. radial geschachtelt mit dem Rotor angeordnet ist.This is achieved according to the invention in that the transmission is at least partially arranged in a radial cavity of the rotor, i.e. is arranged radially nested with the rotor.
Durch das Unterbringen des Getriebes radial innerhalb des Rotors wird der axiale Bauraum deutlich reduziert. Die ganze Anordnung wird um bis zu der gesamten Länge des Getriebes reduziert / verkürzt.By accommodating the gearbox radially inside the rotor, the axial installation space is significantly reduced. The whole arrangement is reduced / shortened by up to the entire length of the gearbox.
Weitergehende Ausführungen sind mit den Unteransprüchen beansprucht und nachfolgend näher erläutert.Further explanations are claimed with the subclaims and explained in more detail below.
Demnach ist es weiterhin von Vorteil, wenn das Getriebe zumindest zwei unterschiedliche Schaltzustände aufweist, vorzugsweise zum An- und Abkoppeln des Rotors von einem Getriebeausgang. Durch diese Ausbildung ist der Elektromotor möglichst effizient betreibbar.Accordingly, it is also advantageous if the transmission has at least two different switching states, preferably for coupling and uncoupling the rotor from a transmission output. As a result of this design, the electric motor can be operated as efficiently as possible.
Wenn das Getriebe als ein Planetengetriebe ausgebildet ist, wird auch eine möglichst kompakte radiale Bauweise erzielt.If the gear is designed as a planetary gear, a radial construction that is as compact as possible is achieved.
In diesem Zusammenhang ist es insbesondere zweckmäßig, wenn mehrere Planetenräder des Getriebes axial vollständig innerhalb des Hohlraums aufgenommen sind.In this context, it is particularly useful if several planet gears of the transmission are axially completely received within the cavity.
Von Vorteil ist es weiterhin, wenn ein erster Getriebebestandteil (des Getriebes) eine durch einen Aktor betätigbare Kupplung / Klauenkupplung, vorzugsweise mit einem sperrbaren ersten Sperrrad und / oder einer Synchronisierung, aufweist. Dadurch wird eine Betätigungsvorrichtung zum Schalten des Getriebes möglichst einfach und kompakt ausgebildet.It is also advantageous if a first transmission component (of the transmission) has a clutch / dog clutch that can be actuated by an actuator, preferably with a lockable first ratchet wheel and / or a synchronization. As a result, an actuating device for switching the transmission is made as simple and compact as possible.
Dabei ist es zusätzlich bevorzugt, das erste Sperrrad als Teil eines Abwurfmechanismus auszubilden.It is also preferred to design the first ratchet wheel as part of a release mechanism.
Das erste Sperrrad ist dann vorteilhafterweise mittels eines ersten Klinkenhebels sperrbar bzw. entkoppelbar. In einer ersten Stellung (Sperrstellung) des ersten Klinkenhebels ist der erste Getriebebestandteil somit drehfest relativ zu einem gehäusefesten Bereich gesperrt und in einer zweiten Stellung (Entsperrstellung) des ersten Klinkenhebels in seiner Rotation freigegeben.The first ratchet wheel can then advantageously be locked or decoupled by means of a first ratchet lever. In a first position (locked position) of the first ratchet lever, the first gear component is locked in a rotationally fixed manner relative to an area fixed to the housing and released in its rotation in a second position (unlocked position) of the first ratchet lever.
Gemäß einer weiter bevorzugten Ausführung ist es auch von Vorteil, wenn das erste Sperrrad mittels eines axial verschiebbaren Sperrrings sperrbar bzw. entkoppelbar ist. Der Sperrring ist vorzugsweise über einen verdrehbaren Rampenring mit einem Stellmotor gekoppelt. Dadurch lässt sich der entsprechende Aktor möglichst kompakt ausbilden.According to a further preferred embodiment, it is also advantageous if the first ratchet wheel can be locked or decoupled by means of an axially displaceable locking ring. The locking ring is preferably coupled to a servomotor via a rotatable ramp ring. As a result, the corresponding actuator can be designed to be as compact as possible.
Eine geeignete Schaltlogik ergibt sich, wenn der erste Getriebebestandteil ein Hohlrad des Getriebes mit ausbildet.A suitable shift logic results when the first transmission component also forms a ring gear of the transmission.
Des Weiteren ist es vorteilhaft, wenn ein zweiter Getriebebestandteil ein, vorzugsweise durch einen weiteren Aktor, besonders bevorzugt durch denselben Aktor wie die Kupplung des ersten Getriebebestandteil betätigbare Kupplung / Klauenkupplung, vorzugsweise mit einem sperrbaren zweiten Sperrrad und / oder einer Synchronisierung, aufweist. Dadurch wird auch der zweite Getriebebestandteil auf möglichst direkte Weise betätigt.Furthermore, it is advantageous if a second transmission component is a clutch / dog clutch that can be actuated, preferably by a further actuator, particularly preferably by the same actuator as the clutch of the first transmission component, preferably with a lockable second one Ratchet wheel and / or a synchronization. As a result, the second transmission component is also actuated as directly as possible.
Dabei ist es bevorzugt, das zweite Sperrrad als Teil einer Parksperre auszubilden.It is preferred to design the second ratchet wheel as part of a parking lock.
In diesem Zusammenhang ist es, wie bereits bei dem ersten Sperrrad von Vorteil, wenn das zweite Sperrrad mittels eines zweiten Klinkenhebels sperrbar bzw. entkoppelbar ist. In einer ersten Stellung (Sperrstellung) dieses zweiten Klinkenhebels ist der zweite Getriebebestandteil drehfest relativ zu einem gehäusefesten Bereich gesperrt und in einer zweiten Stellung (Entsperrstellung) des zweiten Klinkenhebels in seiner Rotation freigegeben.In this context, as with the first ratchet wheel, it is advantageous if the second ratchet wheel can be locked or decoupled by means of a second ratchet lever. In a first position (locking position) of this second ratchet lever, the second gear component is locked in a rotationally fixed manner relative to an area fixed to the housing and released in its rotation in a second position (unlocking position) of the second ratchet lever.
Gemäß einer weiter bevorzugten Ausführung ist es auch von Vorteil, wenn das zweite Sperrrad ebenfalls mittels eines axial verschiebbaren Sperrrings (vorzugsweise über denselben Sperrring wie das erste Sperrrad) sperrbar bzw. entkoppelbar ist.According to a further preferred embodiment, it is also advantageous if the second ratchet wheel can also be locked or decoupled by means of an axially displaceable locking ring (preferably via the same locking ring as the first locking wheel).
Somit ist es weiterhin von Vorteil, wenn je Sperrrad ein Klinkenhebel vorhanden ist, welche Klinkenhebel vorzugsweise über einen gemeinsamen Stellmotor angetrieben / verstellbar sind.Thus, it is also advantageous if there is a ratchet lever for each ratchet wheel, which ratchet levers are preferably driven / adjustable via a common servomotor.
Alternativ ist es von Vorteil, wenn beide Sperrräder über denselben, eine Klauenkupplung bildenden Sperrring mit dem Gehäuse koppelbar oder von diesem entkoppelbar sind.Alternatively, it is advantageous if both ratchet wheels can be coupled to or decoupled from the housing via the same locking ring, which forms a claw coupling.
Als besonders zweckmäßig hat es sich herausgestellt, wenn der zweite Getriebebestandteil einen Planetenträger des Getriebes ausbildet.It has been found to be particularly useful if the second transmission component forms a planet carrier of the transmission.
Weiterhin ist es zweckdienlich, wenn das erste Sperrrad an einem axial aus dem Rotor herausragenden (vorzugsweise zumindest axial in einem Gehäusebestandteil der Anordnung angeordneten) Wellenabschnitt des ersten Getriebebestandteils aufgenommen ist und/oder das zweite Sperrrad an einem axial aus dem Rotor herausragenden (vorzugsweise ebenfalls zumindest teilweise axial in einem Gehäusebestandteil der Anordnung angeordneten) Wellenabschnitt des zweiten Getriebebestandteils aufgenommen ist. Dadurch wird die Zugänglichkeit der Sperrräder, ohne den axialen Bauraum (wesentlich) nachteilig zu beeinflussen, weiter verbessert.Furthermore, it is expedient if the first ratchet wheel is accommodated on a shaft section of the first gear component protruding axially out of the rotor (preferably at least axially arranged in a housing component of the arrangement) and / or the second ratchet wheel on a shaft section protruding axially out of the rotor (preferably also at least partially axially arranged in a housing component of the arrangement) shaft section of the second transmission component is received. As a result, the accessibility of the ratchet wheels is further improved without (significantly) adversely affecting the axial installation space.

Mit anderen Worten ausgedrückt, besteht die erfinderische Lösung darin, den Bauraum (Hohlraum
Ein E-Motor mit gleicher Drehmomentkapazität müsste einen deutlich größeren Luftspaltdurchmesser aufweisen. Unter der Annahme einer konstanten Schubdichte müsste dieser Durchmesser das Wurzel(i)-fache des Motors ohne Getriebestufe betragen, wobei „i“ dem Übersetzungsverhältnis der Getriebestufe entspricht. Gängige Übersetzungen zwischen Sonne und Träger eines Planetengetriebes sind i = ca. 2 bis 5. Daraus folgt der Luftspaltdurchmesser müsste mehr als doppelt so groß sein wie bei einem Motor mit Planetengetriebe. Wollte man die Drehmomenterhöhung durch eine Verlängerung des Motors erzeugen, so müsste dieser die i-fache Länge des Motors mit Getriebe besitzen. Analog müsste der Motor bis zu fünfmal länger sein, bei einem Übersetzungsverhältnis wie oben beschrieben.An electric motor with the same torque capacity would have to have a significantly larger air gap diameter. Assuming a constant thrust density, this diameter would have to be the root (i) -fold of the motor without a gear stage, where "i" corresponds to the gear ratio of the gear stage. Common ratios between the sun and the carrier of a planetary gear are i = approx. 2 to 5. This means that the air gap diameter should be more than twice as large as in a motor with a planetary gear. If you wanted to increase the torque by lengthening the motor, it would have to be i times the length of the motor with gearbox. Similarly, the motor would have to be up to five times longer with a gear ratio as described above.
