“PNEUMATICI DA NEVE PER VEICOLI PESANTI INTEGRATI CON SPATOLE RETRATTILI COMANDATE PNEUMATICAMENTE” "SNOW TIRES FOR HEAVY VEHICLES INTEGRATED WITH PNEUMATICALLY CONTROLLED RETRACTABLE SPATULAS"
DESCRIZIONE DESCRIPTION
Allo stato attuale il mercato propone per la marcia delle autovetture sulla neve i cosiddetti pneumatici invernali la cui struttura garantisce una discreta aderenza sulle superfici innevate o ghiacciate. At present, the market offers so-called winter tires for driving cars on snow, the structure of which guarantees good grip on snowy or icy surfaces.
Una migliore aderenza si ottiene invece dotando le coperture con le catene da neve. Gli automezzi pesanti hanno invece bisogno di adeguate catene per marciare sulla neve soprattutto quando il suo spessore è di un certo rilievo. Better grip is obtained by equipping the tires with snow chains. Heavy vehicles, on the other hand, need adequate chains to drive on the snow, especially when its thickness is of a certain importance.
Le operazioni di montaggio e di smontaggio sono tutt’altro che semplici, comportano un dispendio di tempo per l’applicazione che avviene il più delle volte in ambienti a basse temperature ed innevati che rendono ancora più dispendiosa l’operazione. The assembly and disassembly operations are anything but simple, they involve a waste of time for the application which occurs most of the time in low temperature and snowy environments which make the operation even more expensive.
La presente invenzione riguarda degli pneumatici, prevalentemente per autocarri, che portano delle spatole metalliche integrate in essi e che in condizioni prive di neve sono contenute nel battistrada della ruota, e che all’occorrenza fuoriescono dallo stesso con una semplice operazione. The present invention relates to tires, mainly for trucks, which carry metal spatulas integrated into them and which in snow-free conditions are contained in the tread of the wheel, and which, if necessary, come out of it with a simple operation.
Il pneumatico è sostanzialmente composto di quattro elementi fondamentali: The tire is basically composed of four fundamental elements:
- una carcassa - un insieme di spatole - due circuiti pneumatici di azionamento delle spatole - un battistrada. - a carcass - a set of spatulas - two pneumatic circuits for actuating the spatulas - a tread.
Le tavole di disegno allegate, date a titolo dimostrativo ma non limitativo del trovato, rappresentano di che si tratta. The attached drawing tables, given as a demonstration but not a limitation of the invention, represent what it is about.
La tavola di disegno 1 rappresenta la carcassa (1 ) di un pneumatico con due valvole di gonfiaggio (2) a ciascuna delle quali è collegato un piccolo tubo disposto perimetralmente ad essa e precisamente il (3) che invia a sua volta l’aria compressa ad una serie di microcamere (4), e il (5) che la invia alle microcamere (6), tutte equamente ripartite sopra alla carcassa. The drawing table 1 represents the carcass (1) of a tire with two inflation valves (2) to each of which is connected a small tube arranged perimeter to it and precisely the (3) which in turn sends the compressed air to a series of micro-cameras (4), and the (5) which sends it to the micro-cameras (6), all equally distributed over the casing.
Nella carcassa sono presenti, in corrispondenza delle coppie delle microcamere, una serie di fori (7) per l’aggancio di “gruppi spatola” in seguito descritti. In the casing there are, in correspondence with the pairs of micro-chambers, a series of holes (7) for the attachment of "spatula groups" described below.
La tavola 2 rappresenta una sezione di pneumatico da neve che evidenzia la carcassa (1), i circuiti d’aria (3) e (5), una serie di gruppi spatola (18), ed il battistrada (19) che riporta una serie di finestre in corrispondenza dei gruppi spatola. Table 2 represents a section of a snow tire which highlights the carcass (1), the air circuits (3) and (5), a series of paddle units (18), and the tread (19) showing a series of windows in correspondence of the spatula groups.
La tavola 3 rappresenta un assemblaggio del gruppo spatola (18) , ma con un riporto di gomma (19) sopra alla spatola (8) fino al livello del battistrada. Table 3 represents an assembly of the spatula assembly (18), but with a rubber coating (19) above the spatula (8) up to the level of the tread.
La tavola 4 rappresenta un disegno esploso del “gruppo spatola” (18), ovvero una spatola (8) a forma di farfalla, composta da due ali (9) e (10) saldate ad un perno centrale (11) supportate da una piastra (12), bugnata per aumentarne l’aderenza con la carcassa, e bullonata a questa tramite le viti (13) e gli inserti (14) attraverso i fori (7) e montata in corrispondenza dei fori (7) della carcassa come rappresentato nella tavola 1 . Table 4 represents an exploded drawing of the "spatula group" (18), that is a butterfly-shaped spatula (8), consisting of two wings (9) and (10) welded to a central pin (11) supported by a plate (12), embossed to increase its adherence with the casing, and bolted to this by means of the screws (13) and the inserts (14) through the holes (7) and mounted in correspondence with the holes (7) of the casing as shown in the table 1.
Ogni spatola è posta sulla carcassa in modo che la coppia di ali (9) e (10) si adagi su una coppia di microcamere (4) e (6) rappresentate nella tavola 1. Each spatula is placed on the carcass so that the pair of wings (9) and (10) rests on a pair of micro-cameras (4) and (6) shown in table 1.
L’ ala della farfalla (9) porta all’estremità un’ala secondaria (15) attraverso un perno (16) e due molle (17) che la mantengono perpendicolare all’ala (9) della farfalla. The wing of the butterfly (9) carries a secondary wing (15) at the end through a pin (16) and two springs (17) which keep it perpendicular to the wing (9) of the butterfly.
La tav. 5 rappresenta un gruppo spatola (18) sollevato, in modo da sporgere dal battistrada, con la microcamera (4) in pressione e la microcamera (6) senza pressione. The table 5 shows a paddle assembly (18) raised, so as to protrude from the tread, with the micro-chamber (4) under pressure and the micro-chamber (6) without pressure.
La tav. 6 rappresenta un gruppo spatola (18) ritirato dentro al battistrada, con la microcamera (4) senza pressione e la microcamera (6) in pressione. The table 6 represents a paddle assembly (18) withdrawn inside the tread, with the micro chamber (4) without pressure and the micro chamber (6) under pressure.
La tav. 7 rappresenta un pneumatico in due conformazioni diverse: con le spatole sollevate fuori dal battistrada (22) e con le spatole ritirate all’interno del battistrada (23). The table 7 represents a tire in two different conformations: with the spatulas raised out of the tread (22) and with the spatulas withdrawn inside the tread (23).
La tav. 8 rappresenta un dettaglio della gomma da neve che mette in evidenza le valvole di gonfiaggio (2) con due tipologie di coperchi: uno con una spina centrale (20) e l’altro senza spina (21). The table 8 represents a detail of the snow tire that highlights the inflation valves (2) with two types of lids: one with a central pin (20) and the other without a pin (21).
Senza i coperchi, oppure anche con coperchi del tipo (21), l’aria del pneumatico non entra in nessuno dei tubicini che alimentano le microcamere. Without the covers, or even with covers of the type (21), the air from the tire does not enter any of the tubes that feed the micro-cameras.
Invece chiudendo l’ingresso dell’aria di uno dei due tubicini con il coperchio munito di spina centrale, si metteranno in pressione le microcamere collegate a questo tubicino con il conseguente aumento di volume che farà sollevare le spatole. In definitiva per fare uscire le spatole per la neve si metterà il coperchio munito di spina sulla valvola che alimenta il piccolo tubo (3), mentre per farle rientrare lo si metterà su quella che alimenta il piccolo tubo (5). Instead, by closing the air inlet of one of the two tubes with the lid fitted with a central plug, the micro-cameras connected to this tube will be put under pressure with the consequent increase in volume which will cause the spatulas to lift. Ultimately, to release the trowels for the snow, put the lid with the plug on the valve that feeds the small tube (3), while to bring them back in, you put it on the one that feeds the small tube (5).
La funzione dell’ ala secondaria (15) e delle molle (17) è quella di rendere elastico il gruppo delle spatole rispetto al pneumatico in modo tale che nel caso di urti accidentali l’ala (17) ruoti intorno al perno (16) rientrando nel battistrada (19) proteggendo il sistema di ancoraggio alla carcassa. The function of the secondary wing (15) and of the springs (17) is to make the group of blades elastic with respect to the tire so that in the event of accidental impacts the wing (17) rotates around the pin (16) and retracts in the tread (19) protecting the anchoring system to the carcass.
Queste sono le modalità sufficienti agli esperti del settore per realizzare il trovato; tuttavia in concreta applicazione vi potranno essere delle variazioni fermo restando il principio innovativo caratterizzato dalla ingegnosa combinazione di elementi noti che portano a nuovi risultati e ad un progresso tecnologico innovativo. These are the methods sufficient for those skilled in the art to realize the invention; however in concrete application there may be variations without prejudice to the innovative principle characterized by the ingenious combination of known elements that lead to new results and innovative technological progress.
