Description

Continu variabel transmissiesysteem in een zelfdragend huis.Continuously variable transmission system in a self-supporting housing.

De uitvinding betreft een continu variabel transmissiesysteem omvattende een continu variabele transmissie met twee poeliesets waarvan de schijven een V-vormige 5 groef bepalen, aandrijfmiddelen voor het variëren van de breedte van die groef en een eindloos soepel element dat zich uitstrekt tussen die poeliesets in de groeven daarvan, alsmede een voorwaarts-achterwaartsregeling verbonden aan de as van één van de poeliesets, welke poeliesets, voorwaarts-achterwaartsregeling en koppeling zijn voorzien van een respectievelijke elektrisch bediende actuator.The invention relates to a continuously variable transmission system comprising a continuously variable transmission with two pulley sets, the discs of which define a V-shaped groove, drive means for varying the width of that groove and an endless flexible element extending between said pulley sets in the grooves thereof, as well as a forward-reverse control connected to the shaft of one of the pulley sets, which pulley sets, forward-reverse control and coupling are provided with a respective electrically operated actuator.

10 Een continu variabel transmissiesysteem van dit type is beschreven in WO-A-0116507. Dit bekende continu variabele transmissiesysteem is een "by wire systeem" en bezit het voordeel dat zijn werking volledig elektrisch-mechanisch is. Er is derhalve geen hydraulische olie nodig voor zijn regelfuncties. Als gevolg van dit voordeel is de bedrij fsflexibiliteit van dit continu variabele transmissiesysteem sterk 15 vergroot, en verder vormt dit geen risico met betrekking tot milieuvervuiling als gevolg van mogelijke lekkages van hydraulische olie. Er wordt op gewezen dat, hoewel geen hydraulische olie wordt toegepast in dit bekende systeem voor zijn regelfuncties, in verband met smeringsdoeleinden toch nog olie of een andere geschikte vloei-stof/poedersubstantie wordt toegepast, bijvoorbeeld voor het smeren van de actuatoren, 20 de lagers van de schijven en ook voor het smeren van het contact tussen het drijfmiddel en de schijven.A continuously variable transmission system of this type is described in WO-A-0116507. This known continuously variable transmission system is a "by wire system" and has the advantage that its operation is completely electro-mechanical. Therefore, no hydraulic oil is required for its control functions. As a result of this advantage, the operational flexibility of this continuously variable transmission system is greatly increased, and furthermore it does not present a risk with regard to environmental pollution due to possible leakages of hydraulic oil. It is pointed out that although no hydraulic oil is used in this known system for its control functions, for lubrication purposes still oil or another suitable liquid / powder substance is used, for example for lubricating the actuators, the bearings of the discs and also for lubricating the contact between the propellant and the discs.

Het doel van de onderhavige uitvinding is het verder verbeteren van dat continu variabele transmissiesysteem in die zin dat het kan worden toegepast als een compleet zelfdragend systeem dat gereed is om te worden aangesloten op de aandrijflijn van een 25 voertuig.The object of the present invention is to further improve that continuously variable transmission system in the sense that it can be used as a complete self-supporting system that is ready to be connected to the drive line of a vehicle.

Volgens de uitvinding wordt dit doel bereikt doordat een geïntegreerde startgenerator is voorzien en dat de continu variabele transmissie, de voorwaarts-achterwaartsregeling en de geïntegreerde startgenerator zijn opgenomen in een zelfdragend huis.This object is achieved according to the invention in that an integrated start generator is provided and that the continuously variable transmission, the forward-backward control and the integrated start generator are accommodated in a self-supporting housing.

30 Het opnemen van een geïntegreerde startgenerator, die op zich bekend is, in het continu variabele transmissiesysteem volgens de uitvinding bezit verscheidene voordelen. Allereerst is het niet langer nodig om aanvullende, afzonderlijke componenten toe te passen voor het starten en voor het opwekken van elektrische 10194 57 < 2 stroom in het drijflijnsysteem. Verder bezit de geïntegreerde startgenerator het bekende voordeel dat hij ook gebruikt kan worden voor het verschaffen van een aanvullende koppelversterking aan de aandrijflijn op goed gekozen momenten bij het aandrijven van het betreffende voertuig, bijvoorbeeld bij versnellen, in stadsverkeer en dergelijke.The inclusion of an integrated starter generator, which is known per se, in the continuously variable transmission system according to the invention has several advantages. First of all, it is no longer necessary to use additional, separate components for starting and for generating electric power in the drive line system. Furthermore, the integrated starter generator has the known advantage that it can also be used to provide an additional torque gain to the power train at well-chosen moments when driving the vehicle in question, for example when accelerating, in city traffic and the like.

5 Het opnemen van alle hiervoor genoemde componenten in een zelfdragend huis biedt de mogelijkheid om de totale ruimtebehoefte voor het systeem te beperken, en ook om het systeem op een efficiënte wijze in een complete aandrijflijn op te nemen. Dit heeft niet alleen betrekking op de mechanische verbinding van de continue variabele transmissiesystemen aan het motorblok, maar ook op de elektrische 10 verbinding en de elektrische regelverbindingen aan het totale elektrische en regelsysteem van het voertuig. In dit verband kan het huis zijn voorzien van connectoren voor het aansluiten van de elektrische vermogensleidingen, alsmede verdere connectoren voor het aansluiten van regelleidingen, lucht of oliekoelleidingen en dergelijke.The inclusion of all the aforementioned components in a self-supporting housing offers the possibility of limiting the total space requirement for the system, and also of efficiently incorporating the system into a complete drive train. This relates not only to the mechanical connection of the continuously variable transmission systems to the engine block, but also to the electrical connection and the electrical control connections to the overall electrical and control system of the vehicle. In this connection, the housing can be provided with connectors for connecting the electrical power lines, as well as further connectors for connecting control lines, air or oil cooling lines and the like.

15 De veelzijdigheid van het continu variabele transmissiesysteem volgens de uitvinding kan verder worden vergroot door een koppeling in het huis op te nemen. In dit geval kunnen de koppeling en de geïntegreerde startgenerator worden uitgevoerd als een invoereenheid verbonden aan de ingaande as van de continu variabele transmissie. Als alternatief kunnen de koppeling en de geïntegreerde startgenerator afzonderlijke 20 componenten zijn.The versatility of the continuously variable transmission system according to the invention can be further increased by including a coupling in the housing. In this case, the coupling and the integrated start generator can be implemented as an input unit connected to the input shaft of the continuously variable transmission. Alternatively, the coupling and the integrated starter generator can be separate components.

Verdere voordelen kunnen worden verkregen door een voorwaarts-achterwaartsregeling in het huis op te nemen. Deze voorwaarts-achterwaartsregeling kan worden verbonden aan de ingaande of uitgaande as van de continu variabele transmissie. Als verdere mogelijkheid kan een differentieelmechanisme worden 25 opgenomen in het huis. Naar keuze kan de voorwaarts-achterwaartsregeling worden opgenomen tussen dit differentieelmechanisme en de uitgaande as.Further advantages can be obtained by including a forward-backward control in the housing. This forward-backward control can be connected to the input or output axis of the continuously variable transmission. As a further possibility, a differential mechanism can be included in the housing. Optionally, the forward-reverse control can be included between this differential mechanism and the output shaft.

Het differentieelmechanisme kan door tandwielen worden gekoppeld met zijn poelieset, welke differentieelmechanisme die poelieset overlapt zodanig dat de wielassen evenwijdig naast die poelieset lopen, of daar loodrecht opstaan.The differential mechanism can be coupled by gears to its pulley set, which differential mechanism overlaps that pulley set so that the wheel axles run parallel to that pulley set, or stand perpendicularly there.

30 De continue variabele transmissie van het systeem volgens de uitvinding kan op verschillende manieren worden uitgevoerd. Zo kunnen de poeliesets bijvoorbeeld elk een holle as bezitten waarin een schroefmechanisme is opgenomen dat aandrijfbaar is door een elektrische motor. Als alternatief kunnen de poeliesets elk een geïntegreerde 1 01 94 57 ! 3 naaflagereenheid bezitten die verschuifbaar is met betrekking tot het huis. In dit geval worden de poeliesets ook door elektrische motoren aangedreven. Een voorbeeld van dergelijke poeliesets is beschreven in NL-A-1019204, die geen voorpublicatie is.The continuously variable transmission of the system according to the invention can be carried out in various ways. For example, the pulley sets can each have a hollow shaft in which a screw mechanism is accommodated that can be driven by an electric motor. Alternatively, the pulley sets can each have an integrated 1 01 94 57! 3 have a hub bearing unit that is slidable with respect to the housing.

Als alternatief kan de koppeling een concentrisch actuatorsysteem bevatten.Alternatively, however, the coupling may comprise a known disc spring which is operated by the screw mechanism via a lever. In that case the screw mechanism can be placed outside the relevant housing, the lever 15 protruding through an opening in the housing. Alternatively, the coupling may include a concentric actuator system.

Bij voorkeur zijn de aandrijfmiddelen van de poeliesets, de voorwaarts-achterwaartsregeling, de koppeling en de geïntegreerde startgenerator opgenomen in een gesloten lusconfiguratie met de regelmiddelen. Die regelmiddelen worden gevoed 20 met signalen van de sensoren.Preferably, the drive means of the pulley sets, the forward-reverse control, the clutch and the integrated start generator are included in a closed loop configuration with the control means. Those control means are supplied with signals from the sensors.

In verband met de eenvoud van vervaardiging, kunnen de voorwaarts-achterwaartsregeling, de koppeling, de ISG, het differentieel en de continu variabele transmissie- en regeleenheden zijn opgenomen in afzonderlijke modules.For the sake of simplicity of manufacture, the forward-reverse control, the clutch, the ISG, the differential and the continuously variable transmission and control units may be included in separate modules.

Verder kan, zoals genoemd, het huis een oliebad bevatten voor het smeren en 25 koelen van de continu variabele transmissie.
