TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
Descrizione dell’invenzione industriale avente per titolo “ Freni a raffreddamento ad acqua “ Description of the industrial invention entitled "Water-cooled brakes"
Il presente sistema frenante con raffreddamento ad acqua impedisce il surriscaldamento della parte mobile da frenare. La maggior parte dei freni è del tipo ad attrito e funziona premendo una superficie fissa contro una superficie di caratteristiche analoghe della parte mobile da frenare o arrestare, le due superficie strisciano l’una sull’altra e l’energia cinetica immagazzinata nella parte mobile da frenare viene trasformata per attrito in calore. Il calore che si sviluppa nella parte mobile da frenare viene lentamente dissipato nell’aria, e nel caso di un uso più frequente dei freni il sistema di raffreddamento ad aria non è sufficiente per mantenere una temperatura controllata sulla parte mobile da frenare, ma può raggiungere delle temperature molto elevate che possono compromettere l’efficienza dell’impianto frenante. Quando il clima è umido o piovoso, nella parte mobile da frenare si deposita una patina di acqua che al momento dell’uso dei freni quando viene premuta la superficie fissa contro la superficie mobile l’umidità che si è depositata sugli organi di frenatura impedisce un’immediata azione frenante finché questa non viene evaporata dal calore che si sviluppa dall’attrito delle due superficie mobile e fissa. This water-cooled brake system prevents overheating of the moving part to be braked. Most brakes are of the friction type and work by pressing a fixed surface against a surface of similar characteristics of the moving part to be braked or stopped, the two surfaces sliding on each other and the kinetic energy stored in the moving part to be braking is transformed by friction into heat. The heat that develops in the moving part to be braked is slowly dissipated into the air, and in the case of more frequent use of the brakes the air cooling system is not sufficient to maintain a controlled temperature on the moving part to be braked, but it can reach very high temperatures which can compromise the efficiency of the braking system. When the climate is humid or rainy, a patina of water is deposited in the mobile part to be braked which, when the brakes are used, when the fixed surface is pressed against the mobile surface, the humidity that has deposited on the braking components prevents a immediate braking action until this is evaporated by the heat that develops from the friction of the two mobile and fixed surfaces.
La presente innovazione con rimpianto frenante a raffreddamento ad acqua ha lo scopo di eliminare in via principale gli inconvenienti sopra descritti. Una caratteristica dell’impianto frenante e che sono ricavate nella parte mobile da frenare delle intercapedini dove circola l’acqua collegata con l’impianto di raffreddamento del motore. L’ acqua che circola sulle intercapedini raggiunge una temperatura di circa 87° C. portando allo stesso tempo la stessa temperatura sulla parte mobile da frenare, in questo modo quando il clima è umido o piovoso l’umidità o l’acqua che si deposita sugli organi frenanti viene immediatamente evaporata mantenendo la parte mobile da frenare asciutta e dando il vantaggio quando viene azionato il freno di diminuire lo spazio di frenatura. The present innovation with water-cooled braking system has the purpose of eliminating the above-described drawbacks in the main. A feature of the braking system is that they are obtained in the mobile part to be braked of the cavities where the water flows connected to the engine cooling system. The water that circulates on the cavities reaches a temperature of about 87 ° C. at the same time bringing the same temperature on the mobile part to be braked, in this way when the climate is humid or rainy the humidity or water that is deposited on the braking parts is immediately evaporated, keeping the mobile part to be braked dry and giving the advantage when the brake is activated to reduce the braking distance.
Quando la superficie fissa viene premuta sulla parte mobile da frenare le due parti che strisciano l’una sull’altra sviluppano calore, il calore che si sviluppa sulla parte mobile da frenare viene dissipato dall’afflusso dell’acqua che circola sulle intercapedini impedendo in questo modo il surriscaldamento della parte mobile da frenare, anche quando viene fatto un uso improprio dei freni. When the fixed surface is pressed on the movable part to be braked, the two parts that slide on each other develop heat, the heat that develops on the movable part to be braked is dissipated by the flow of water that circulates on the cavities, thus preventing way the overheating of the moving part to be braked, even when improper use of the brakes is made.
Queste e altre caratteristiche risulteranno ora maggiormente in relazione ad una forma di esecuzione data solo a titolo di esempio di un impianto frenate con raffreddamento ad acqua provvisti dei perfezionamenti in oggetto, con l’ausilio dei disegni allegati. These and other characteristics will now be more in relation to an embodiment given only by way of example of a water-cooled braking system provided with the improvements in question, with the aid of the attached drawings.
La figura 1 mostra la parte mobile da frenare e la parte fissa sezionata a metà. La figura 2 mostra in prospettiva la parte mobile da frenare parzialmente sezionato. Figure 1 shows the movable part to be braked and the fixed part sectioned in half. Figure 2 shows in perspective the moving part to be braked partially sectioned.
La figura 3 mostra lo schema di funzionamento dei freni collegato con l’impianto di raffreddamento ad acqua del motore. Figure 3 shows the operating diagram of the brakes connected with the engine water cooling system.
La figura 4 mostra lo schema di funzionamento della parte mobile da frenare in vista frontale. Figure 4 shows the operation diagram of the movable part to be braked in a front view.
In riferimento ai disegni allegati che consentono di individuare alcune parti degli organi di frenatura che permettono di capire il suo funzionamento, con 1 fig. 1, 2, 3, 4 è indicato la parte mobile da frenare, con 2 il raccordo che consente l’ingresso dell’acqua dell’impianto di raffreddamento del motore sulla parte mobile da frenare 1 collegato tramite un manicotto 4 dove tra i due si trova una valvola di ritenuta 5 per non consentire la fuoriuscita dell’acqua di raffreddamento mentre viene effettuata la manutenzione degli organi di frenatura o nell’eventuale rottura del raccordo 2. Il raccordo 2 e 2b é collegato tra il cuscinetto a tenuta ermetica 3, 3b, 3c, 3d che permette di non rotare sul proprio asse insieme alla parte mobile da frenare e viene sostenuto dalle frequenti oscillazioni dai sostegni 6, 6b che vengono fissati nell’incavo 11, 11b e trattenuti da dei fermi situati nel mozzo 10. L’acqua che passa attraverso il raccordo 2 viene inserita su un canale 7 e la pressione che viene esercitata dalla pompa centrifuga ( non mostrata sul disegno ) dell’impianto di raffreddamento del motore viene spinta attraverso il foro 8 che comunica sull’intercapedine 9 che consente in questo modo di mantenere costante la temperatura della parte mobile da frenare, l’acqua che attraversa l’intercapedine 9 fuoriesce attraverso il foro 8b che comunica sul canale 7b e fuoriesce attraverso il raccordo 2b collegato tra il cuscinetto 3c e 3d con lo stesso sistema di funzionamento del cuscinetto 3 e 3b dove sul raccordo 2b passa l’afflusso dell’acqua che circola attraversando il manicotto 4b e ritorna sullo impianto di raffreddamento del motore. I cuscinetti 3, 3b, 3c, 3d vengono tenuti saldi alla parte mobile da frenare per mezzo delle viti 12. With reference to the attached drawings which allow to identify some parts of the braking members which allow to understand its operation, with 1 fig. 1, 2, 3, 4 indicates the movable part to be braked, with 2 the fitting that allows the water from the cooling system of the engine to enter the movable part to be braked 1 connected by means of a sleeve 4 where between the two finds a check valve 5 to prevent the cooling water from escaping while maintenance is being carried out on the braking components or in the eventual breakage of fitting 2. The fitting 2 and 2b is connected between the hermetically sealed bearing 3, 3b , 3c, 3d which allows not to rotate on its own axis together with the movable part to be braked and is supported by frequent oscillations by the supports 6, 6b which are fixed in the recess 11, 11b and held by stops located in the hub 10. The water passing through the fitting 2 is inserted on a channel 7 and the pressure that is exerted by the centrifugal pump (not shown on the drawing) of the engine cooling system is pushed through the hole 8 which communicates on The interspace 9 which thus allows the temperature of the movable part to be braked to be kept constant, the water passing through the interspace 9 comes out through the hole 8b which communicates on the channel 7b and exits through the fitting 2b connected between the bearing 3c and 3d with the same operating system of the bearings 3 and 3b where on the fitting 2b the flow of water passes through the sleeve 4b and returns to the cooling system of the engine. Bearings 3, 3b, 3c, 3d are held firmly to the moving part to be braked by means of screws 12.
In pratica i particolari di esecuzione le dimensioni i materiali le forme e simili del’impianto della parte mobile da frenare potranno comunque variare senza pertanto uscire dall’ambito del trovato e quindi della privativa industriale. In practice, the details of the execution, the dimensions, the materials, the shapes and the like of the system of the mobile part to be braked may in any case vary without therefore departing from the scope of the invention and therefore of the industrial property.
