Description

DESCRIZIONE DESCRIPTION

Oggetto della descrizione e del brevetto è il sistema di motorizzazione di un quadriciclo leggero o pesante. Questo sistema è composto da due motori. Uno elettrico, principale e uno termico secondario collegati o meno da una trasmissione apposita che permette il funzionamento di entrambi i motori, ma separatamente. I due motori sono complementari e indipendenti, per quanto riguarda l'alimentazione e sono concepiti per funzionare singolarmente . The subject of the description and of the patent is the motorization system of a light or heavy quadricycle. This system consists of two motors. One electric, main and one secondary thermal connected or not by a special transmission that allows the operation of both motors, but separately. The two motors are complementary and independent, as regards the power supply and are designed to work individually.

Il quadriciclo è equipaggiato con due motori distinti e non funzionanti contemporaneamente nella fase motrice di spinta. The quadricycle is equipped with two separate engines that do not work at the same time in the thrust phase.

Il motore elettrico è il motore principale del veicolo, ed è questo motore quello previsto per il normale funzionamento del quadriciclo, che consente il suo utilizzo nei centri storici e viaggiare con costi di esercizio piccolissimi. The electric motor is the main motor of the vehicle, and it is this motor that is foreseen for the normal operation of the quadricycle, which allows it to be used in historic centers and to travel with very low operating costs.

Il motore endotermico permette il movimento del veicolo solo per completare il viaggio in caso di avaria al sistema principale o di batteria principale con carica esaurita. Quindi la potenza trasmessa da questo motore non è addizionabile a quella trasmessa normalmente dal motore elettrico. The internal combustion engine allows the vehicle to move only to complete the journey in case of failure of the main system or of the main battery with depleted charge. Therefore the power transmitted by this motor cannot be added to that normally transmitted by the electric motor.

L'avviamento del motore endotermico, è gestito dalla centralina controllo motopropulsore che individua il momento in cui la batteria principale non consente più la marcia corretta della vettura. The starting of the internal combustion engine is managed by the powertrain control unit which identifies the moment when the main battery no longer allows the vehicle to run correctly.

Il motore endotermico quando entra in funzione, per le cause sopra citate, in certe condizioni di esercizio, può effettuare la ricarica delle batterie. Questa funzione viene gestita da una centralina elettronica che verifica se esistono le condizioni tecniche e di sicurezza, per ricaricare la batteria senza penalizzare la marcia della vettura. When the internal combustion engine comes into operation, for the reasons mentioned above, under certain operating conditions, it can recharge the batteries. This function is managed by an electronic control unit that checks whether the technical and safety conditions exist, to recharge the battery without penalizing the running of the car.

I due motori, uno elettrico e l'altro termico, possono essere collegati tra loro attraverso una speciale trasmissione che permette al gruppo motopropulsore di realizzare con gli opportuni rapporti The two motors, one electric and the other thermal, can be connected to each other through a special transmission that allows the powertrain to achieve with the appropriate ratios

- il normale funzionamento della vettura in modalità elettrica, - il recupero di energia in frenata o in rilascio acceleratore, - la ricarica delle batterie quando la vettura è in funzionamento con il motore secondario a benzina. - normal operation of the car in electric mode, - energy recovery under braking or accelerator release, - recharging the batteries when the car is running with the secondary petrol engine.

- L'inserimento della Retromarcia - Engagement of Reverse

Lo schema della trasmissione è riportato nelle fig. 1 e 2 The transmission scheme is shown in figs. 1 and 2

II motore principale elettrico è collegato tramite un sistema di ingranaggi, sia al motore secondario, sia alla corona di uscita del moto, collegata alle ruote tramite un differenziale. The main electric motor is connected by means of a system of gears, both to the secondary motor and to the output crown of the motion, connected to the wheels by means of a differential.

Il motore secondario con la sua trasmissione continua a cinghia è collegato al motore principale elettrico tramite una ruota senza fine che permette di trasmettere il moto alle ruote quando il motore principale è privo di alimentazione. The secondary motor with its continuous belt transmission is connected to the main electric motor via an endless wheel which allows the motion to be transmitted to the wheels when the main motor is without power.

Questo sistema permette l'uso indipendente e non contemporaneo delle due motorizzazioni e quindi: This system allows the independent and non-simultaneous use of the two engines and therefore:

a) Durante la marcia normale, cioè nelle condizioni standard di utilizzo della vettura il motore ausiliario endotermico non è collegato alla trasmissione, grazie all'uso della ruota libera rappresentata in fig. 2. In queste condizioni nelle fasi di frenata o rilascio acceleratore, il motore elettrico principale diventa un freno motore che produce energia elettrica per le batterie. Il tutto ovviamente gestito da una apposita centralina di controllo di tutto il sistema motoproplusore a) During normal driving, i.e. in the standard conditions of use of the car, the endothermic auxiliary engine is not connected to the transmission, thanks to the use of the free wheel shown in fig. 2. Under these conditions, during the braking or accelerator release phases, the main electric motor becomes an engine brake which produces electrical energy for the batteries. All obviously managed by a special control unit of the entire motoproplusore system

b) Durante la marcia con motore ausiliario, il motore principale viene trascinato dal motore endotermico e funzionerà come dinamo è potrà produrre energia elettrica per le batterie, se le condizioni di utilizzo della vettura lo consentono. Tutto questo è sempre gestito dalla apposita centralina di controllo sopra menzionata b) When driving with an auxiliary engine, the main engine is driven by the internal combustion engine and will work as a dynamo and will be able to produce electricity for the batteries, if the conditions of use of the car allow it. All this is always managed by the appropriate control unit mentioned above

c) Quando si utilizza il motore ausiliario endotermico, questa speciale trasmissione permette di inserire uno specifico rapporto per avere anche una retromarcia, indispensabile su una vettura, anche se si tratta di un quadriciclo leggero o pesante. c) When using the endothermic auxiliary engine, this special transmission allows you to insert a specific gear to also have a reverse gear, which is essential on a car, even if it is a light or heavy quadricycle.

L'inserimento della Retromarcia avviene meccanicamente spostando la coppia di ruote gemellate permettendo il disinnesto del rapporto normale di marcia avanti e inserendo un rapporto che non essendo più derivato dal rapporto del motore principale, ma diretto sulla corona finale della trasmissione permette l'inversione del senso di rotazione, quindi la possibilità di procedere a marcia indietro Reverse gear is engaged mechanically by moving the pair of twin wheels allowing the disengagement of the normal forward gear ratio and inserting a gear which, being no longer derived from the main engine ratio, but directed on the final gear ring of the transmission, allows the direction to be reversed. of rotation, therefore the possibility to proceed in reverse
