TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
Questo brevetto fa riferimento al campo della tecnica relativo ai dispositivi utilizzati nel settore automobilistico per migliorare la sicurezza e le prestazioni dei veicoli su strada. In particolare l'invenzione riguarda un sistema di sicurezza per il miglioramento delle prestazioni di frenata di un veicolo su pneumatici. This patent refers to the field of technology relating to devices used in the automotive sector to improve the safety and performance of vehicles on the road. In particular, the invention relates to a safety system for improving the braking performance of a vehicle on tires.
Fino a 15-20 anni fa la sicurezza attiva dipendeva completamente dal modo in cui un autoveicolo era progettato e regolato: la rigidezza del telaio, la raffinatezza delle sospensioni, la qualità dell'impianto frenante, i pneumatici: tutto, in sostanza, era legato alle caratteristiche meccaniche del mezzo. Until 15-20 years ago, active safety depended completely on the way in which a vehicle was designed and regulated: the stiffness of the chassis, the refinement of the suspension, the quality of the braking system, the tires: everything, in essence, was linked the mechanical characteristics of the vehicle.
Con I' avvento dell'elettronica, caratterizzata da sempre maggiore affidabilità e autorevolezza, l'industria della componentistica ha cominciato a proporre accessori che rendevano più facile il controllo dell'auto in condizioni d'emergenza, aumentando fortemente la possibilità di evitare incidenti. With the advent of electronics, characterized by ever greater reliability and authority, the component industry began to offer accessories that made it easier to control the car in emergency conditions, greatly increasing the possibility of avoiding accidents.
Il primo di questi accessori è stato l'ABS, acronimo tedesco di Antiblockiersystem, cioè sistema anti bloccaggio dei freni; il dispositivo è stato messo a punto dalla Bosch. The first of these accessories was ABS, the German acronym for Antiblockiersystem, that is, the anti-locking system of the brakes; the device was developed by Bosch.
Ad oggi però tutte le soluzioni presenti per garantire il controllo del veicolo si basano su un approccio diretto, ovvero sono dispositivi o congegni che agiscono cercando di sfruttare al meglio l'aderenza messa a disposizione dal fondo stradale. L'aderenza, ovvero il contatto ruota-strada, dipende da molteplici parametri, il più importante di questi è legato all'attrito messo a disposizione dal fondo stradale.Si definisce μ coefficiente di attrito radente, ovvero il rapporto esistente tra la forza resistente, attrito, e la forza agente. To date, however, all the solutions available to ensure vehicle control are based on a direct approach, i.e. they are devices or devices that act trying to make the most of the grip made available by the road surface. The grip, that is the wheel-road contact, depends on many parameters, the most important of these is linked to the friction made available by the road surface. friction, and the acting force.
L'attrito radente non è dipendente dall'estensione della superficie di contatto, purché essa non sia troppo piccola. Il coefficiente d'attrito radente subisce variazioni con il variare della temperatura della sede stradale e dei pneumatici. The sliding friction is not dependent on the extension of the contact surface, as long as it is not too small. The sliding friction coefficient undergoes variations with the variation of the temperature of the road surface and of the tires.
Il coefficiente di attrito stradale cambia in base al fondo stradale: a parità di fondo stradale, tuttavia, l'attrito cala nettamente nella condizione di fondo stradale bagnato. The road friction coefficient changes according to the road surface: on the same road surface, however, the friction drops significantly in the condition of a wet road surface.
Il coefficiente di attrito è definito, in gergo automobilistico, coefficiente di aderenza μ_0 che, in sostanza, non è altro che il valore locale del coefficiente di attrito statico, detto anche di primo distacco, fra ruota e strada. The coefficient of friction is defined, in automotive jargon, as the coefficient of adhesion μ_0 which, in essence, is nothing more than the local value of the static coefficient of friction, also known as the first detachment, between wheel and road.
Il coefficiente di aderenza fra ruota e strada dipende da innumerevoli fattori. Una volta fissata la natura delle superfici a contatto, si ha dipendenza dai valori locali della velocità di strisciamento della temperatura e della pressione relativa. The coefficient of adhesion between the wheel and the road depends on numerous factors. Once the nature of the surfaces in contact has been established, it depends on the local values of the sliding speed of the temperature and of the relative pressure.
In termini percentuali dalla condizione di strada asfaltata asciutta alla condizione di strada asfaltata bagnata si ha una perdita di attrito del 50%, che di conseguenza si trasforma in una perdita delle prestazioni di controllo dell'autoveicolo. In percentage terms, from the condition of a dry asphalt road to the condition of a wet asphalt road there is a loss of friction of 50%, which consequently translates into a loss of the vehicle's control performance.
A parità di velocità, autoveicolo e pneumatici sulla stessa strada asfaltata, si avrebbe una forza frenante dell'autoveicolo di circa il 50% in meno rispetto alla condizione di strada asfaltata asciutta At the same speed, vehicle and tires on the same asphalt road, the braking force of the vehicle would be approximately 50% less than in the condition of a dry asphalt road.
L'oggetto della presente invenzione si basa proprio sul recupero dell'attrito perso da ghiaccio acqua o viscidume, cercando di eliminare la causa che ha generato la diminuzione dell'attrito a disposizione. The object of the present invention is based precisely on the recovery of the friction lost by ice, water or viscidume, trying to eliminate the cause that generated the decrease in available friction.
Sullo stesso fondo stradale si ha una notevole differenza frenante in due condizioni climatiche differenti. Ovvero, sullo stesso fondo stradale, per il fatto che ci si trovi in una giornata piovosa, si perde un aliquota pari proprio al 50% di attrito stradale, dovuto appunto alla pioggia. On the same road surface there is a considerable braking difference in two different climatic conditions. That is, on the same road surface, due to the fact that you are on a rainy day, you lose a rate equal to 50% of road friction, due precisely to the rain.
L'oggetto di questa invenzione si incentra proprio sulla possibilità di recuperare questo attrito eliminandone la causa della brusca perdita. The object of this invention focuses precisely on the possibility of recovering this friction by eliminating the cause of the sudden loss.
L'invenzione riguarda un dispositivo che, in specifiche condizioni del veicolo come la perdita di aderenza del pneumatico imputabile alla brusca riduzione di attrito stradale, possa recuperare l'attrito perso aumentando quindi la forza frenante, e di conseguenza il controllo e la sicurezza del veicolo. The invention relates to a device which, in specific vehicle conditions such as the loss of grip of the tire due to the abrupt reduction of road friction, can recover the friction lost thus increasing the braking force, and consequently the control and safety of the vehicle. .
In particolare l'invenzione riguarda un sistema montato su veicoli con pneumatici che invia sulla strada un getto di aria ad aita pressione e temperatura, pulendola da acqua, ghiaccio o viscidume, recuperando così parte dell'attrito stradale perso, costituito da: In particular, the invention relates to a system mounted on vehicles with tires which sends a jet of air at high pressure and temperature onto the road, cleaning it from water, ice or viscidume, thus recovering part of the lost road friction, consisting of:
- un unità di controllo (4) che coliegata al veicolo (8) su pneumatici (7), attiva in condizioni di perdita di aderenza del pneumatico (7), un compressore (1) ed una resistenza elettrica (3) Tav. 1 Fig. 1; - a control unit (4) which, connected to the vehicle (8) on tires (7), activates in conditions of loss of grip of the tire (7), a compressor (1) and an electrical resistance (3) Tab. 1 Fig . 1;
- un compressore (1), attivato dall'unità di controllo (4), che invia un getto di aria (5) ad alta pressione all'interno di un ugello (3) cui esso è collegato Tav. 1 Fig. 1; - a compressor (1), activated by the control unit (4), which sends a jet of air (5) at high pressure inside a nozzle (3) to which it is connected Table 1 Fig. 1;
- una resistenza elettrica (3) posta all'interno dell'ugello (2), attivata dall'unità di controllo (4), che riscalda il getto di aria (5) all'interno dell'ugeilo (3), inviato dal compressore (1) Tav. - an electric resistance (3) placed inside the nozzle (2), activated by the control unit (4), which heats the jet of air (5) inside the nozzle (3), sent by the compressor (1) Table
1 Fig. 1; 1 Fig. 1;
- un ugello (3), montato appena dinanzi lo pneumatico (7), che invia a sua volta il getto di aria (5) ad alta pressione e temperatura, inviato dal compressore (1) e riscaldato dalla resistenza elettrica (3), direttamente sulla strada percorsa dallo pneumatico (7) pulendo la strada (9), da acqua, ghiaccio o viscidume (9), recuperando così parte dell'attrito stradale perso Tav. 1 Fig. 1 e Tav. 2 Fig. 2; - a nozzle (3), mounted just in front of the tire (7), which in turn sends the jet of air (5) at high pressure and temperature, sent by the compressor (1) and heated by the electrical resistance (3), directly on the road traveled by the tire (7) by cleaning the road (9), from water, ice or slime (9), thus recovering part of the road friction lost Tav. 1 Fig. 1 and Tav. 2 Fig. 2;
Il funzionamento è molto semplice: nell'istante in cui lo pneumatico inizia a perdere di aderenza, l'unità di controllo (4) attiva istantaneamente il compressore (1) e la resistenza elettrica (3) in modo da inviare un getto di aria (5) ad alta pressione e temperatura che asciughi immediatamente il fondo stradale anteriormente ai pneumatico, così da recuperare l'attrito portato via dall'acqua Tav. 2 Fig. 2. Operation is very simple: the moment the tire begins to lose grip, the control unit (4) instantly activates the compressor (1) and the electrical resistance (3) in order to send a jet of air ( 5) at high pressure and temperature that immediately dries the road surface in front of the tire, so as to recover the friction carried away by the water Table 2 Fig. 2.
Allo stesso modo, il getto di aria (5) ad alta pressione e temperatura spazza via polvere o ghiaia che, contribuiscono in maniera significativa a ridurre l'attrito stradale. Likewise, the jet of air (5) at high pressure and temperature sweeps away dust or gravel which contribute significantly to reducing road friction.
Il sistema, può funzionare ad esempio in concomitanza con l'Abs ormai ampiamente collaudato, fornendo dunque un aumento della sicurezza del veicolo in caso di perdita di aderenza dei pneumatici. The system, for example, can work in conjunction with the now widely tested ABS, thus providing an increase in vehicle safety in case of loss of tire grip.

Table 2 Fig. 2: Side view of the application of the invention showing the operation of the braking system mounted on a motor vehicle (8) during the sending of the jet of air (5) at high pressure and temperature which immediately dries the road surface in front of the tire, so as to recover the friction carried away by the water.
