Disc brake comprising at least one disc (11, 12.21, 22, 31, 32, 41, 42, 51) constrained to the rotating el oment to be braked, and at least one corresponding braking pad (52) capable of acting in relative sliding on the disc (i l, 12, 21, 22, 31, 32, 41, 42.
51 ) ed almeno una pinza (54) atta a spingere la pastiglia di trenaggio sul disco, 51) and at least one caliper (54) able to push the brake pad on the disc,
La peculiarit? del freno risiede nel latto clic nel disco (1 1, 12, 21, 22. 31, 32, 41, 42, 51), o nella pastiglia (52) o nella pinza (54) o in tutti i suddetti componenti ? prevista la inserzione di materiale (14, 24, 36, 46, 53) ad alta capacit? di conduzione di calore c conseguentemente di dissipazione di calore, come rame, argento ecc.. o una lega di questi metalli, o un qualsiasi altro materiale con alta capacit? di conduzione e dissipazione di calore. The peculiarity? of the brake resides in the click in the disc (1 1, 12, 21, 22. 31, 32, 41, 42, 51), or in the pad (52) or in the caliper (54) or in all of the aforementioned components? expected the insertion of material (14, 24, 36, 46, 53) with high capacity? of heat conduction and consequently of heat dissipation, such as copper, silver etc .. or an alloy of these metals, or any other material with high capacity? conduction and heat dissipation.
La presente invenzione si riferisce al campo dei dispositivi di frenatura, e pi? precisamente ha per oggetto un freno di tipo a disco particolarmente ma non esclusivamente utile per veicoli su ruote Il principio di funzionamento dei freni a disco prevede in pratica almeno un disco di frenata vincolato coassialmente all'elemento in rotazione da frenare, e almeno un corrispondente corpo d'attrito (chiamato comunemente pastiglia del freno) che viene spinto sulla superficie del disco ortogonalmente a questa, ossia parallelamente all'asse di rotazione, da una pinza azionata in genere attraverso pressione idraulica. Lo strisciamento della pastiglia (o delle pastiglie) sul disco genera calore (s? ha trasformazione di energ?a cinetica in energia termica), calore che deve essere dissipato nel modo pi? efficiente possibile per evitare deformazioni del disco e degli altri componenti del dispositivo di frenatura, deformazioni che pregiudicherebbero l'efficienza de! sistema frenante. La insufficiente dissipazione del calore generato dalla azione di frenatura pu? portare altres? al fenomeno detto del ?fading" che origina dal deteriorarsi, per effetto dell'eccessivo calore, alla superficie di contatto, del materiale di cui ? composta la pastiglia generante attrito con diminuzione del coefficiente di attrito e scadimento dell?efficienza del sistema frenante e. ancora, pu? causare l'ebollizione del liquido deirimpianto idraulico con caduta di pressione neirimpianto stesso e perdita dell'azione frenante, per formazione di bolle gassose. The present invention relates to the field of braking devices, and more? precisely it has as its object a disc brake particularly but not exclusively useful for vehicles on wheels. of friction (commonly called brake pad) which is pushed onto the disc surface orthogonally to this, ie parallel to the rotation axis, by a caliper generally operated by hydraulic pressure. The sliding of the pad (or pads) on the disc generates heat (if kinetic energy is transformed into thermal energy), heat that must be dissipated in the most effective way. efficient as possible to avoid deformations of the disc and of the other components of the braking device, deformations that would affect the efficiency of the braking system. The insufficient dissipation of the heat generated by the braking action can? bring also? to the phenomenon known as? fading "which originates from the deterioration, due to the effect of excessive heat, of the material of which the pad is made, generating friction with a decrease in the friction coefficient and a deterioration in the efficiency of the braking system e. furthermore, it can cause the hydraulic system liquid to boil with a pressure drop in the system itself and loss of the braking action, due to the formation of gaseous bubbles.
Per smaltire il calore generato dall'azione di frenata, sono state messe a punto diverse soluzioni, molte delle quali prevedono una particolare configurazione del disco, come ad esempio dischi pieni con fori trasversali per aumentare la superficie di scambio con l'aria (superficie radiante) oppure diselli dotati d? un profilo esterno sagomato a definire delle appendici forate (disco ?margherita") ? ancora dischi ?ventilati? ovvero dischi formati da una coppia di dischi pi? sottili affiancati e solidali, che definiscono centralmente una intercapedine ventilante, o ancora dischi ?ventilati? e forati trasversalmente. Nel campo dei dispositivi di frenatura, l'esigenza principale ? quella di aumentare le prestazioni di fienaia senza pregiudicare pi? di tanto l'aspetto dimensionale dei componenti il sistema. To dispose of the heat generated by the braking action, various solutions have been developed, many of which provide for a particular configuration of the disc, such as solid discs with transverse holes to increase the exchange surface with the air (radiant surface ) or diselli with d? an external profile shaped to define perforated appendages (disk? margherita ")? again? ventilated? disks or disks formed by a pair of thinner disks side by side and integral, which centrally define a ventilating cavity, or even? ventilated? disks and In the field of braking devices, the main need is to increase the performance of the hay without compromising too much the dimensional aspect of the system components.
Questo sia per non aumentare le masse non sospese, che inciderebbero negativamente sulla tenuta del veicolo, sia per non aumentare l?effetto giroscopico aumentando le masse in rotazione, Queste esigenze sono per?, relativamente ai dispositivi di frenatura, di difficile raggiungimento perch? per aumentare la potenza frenante ? inevitabile aumentare la superf?cie di stri sci amento disco/pastiglia con conseguente aumento dimensionalo dei componenti e quindi delfiniere dispositivo. Viene allora ricercala una maggiore efficienza attraverso una migliorata capacit? del sistema a disperdere calore. Quindi fin traduzione d? dischi pieni ma forati in senso parallelo all'asse di rotazione e capaci di una maggiore superficie radiante, di dischi ?ventilati? cio? composti da due semidischi affiancati con capacit? di circolazione rii aria al loro interno, talvolta con disegni interni tali da generare un effetto ?turbina?, di dischi ventilati e forati cec. This is so as not to increase the unsprung masses, which would negatively affect the vehicle's grip, and to not increase the gyroscopic effect by increasing the rotating masses. to increase braking power? it is inevitable to increase the disc / pad sliding surface with a consequent increase in the size of the components and therefore the final device. Is it then sought a greater efficiency through an improved capacity? of the system to disperse heat. So fin translation d? solid discs but perforated parallel to the rotation axis and capable of a greater radiating surface, of? ventilated? that is? composed of two semi-discs side by side with capacity? air circulation inside them, sometimes with internal designs such as to generate a "turbine" effect, of ventilated and perforated discs cec.
Esiste addirittura in lettera tura almeno una invenzione che cerca di raggiungere lo scopo di una maggiore efficienza di dissipazione del calore attraverso un impianto di raffreddamento a liquido. Scopo della presente invenzione ? quello d? realizzare un dispositivo di frenatura del tipo freno a disco che consenta di aumentare la efficienza del sistema aumentando la capacit? di dissipazione del calore generato dalla azione frenante attraverso l'inserimento nel disco, nella pastiglia, nella pinza, o in tutti i suddetti componenti di inserti d? varia forma e dimensione, realizzati in materiali ad alta conducibilit? termica. There is even in literature at least one invention which seeks to achieve the object of greater heat dissipation efficiency through a liquid cooling system. Purpose of the present invention? what d? to realize a braking device of the disc brake type that allows to increase the efficiency of the system by increasing the capacity? of dissipation of the heat generated by the braking action through the insertion in the disc, in the pad, in the caliper, or in all the aforementioned components of inserts d? various shape and size, made of materials with high conductivity? thermal.
La conducibilit? termica, espressa in W/(m x C?) cio? in Watt / metri x Celsius ? compresa tra 36 ? 61 per gli acciai pi? o meno legati, mentre ? di circa 420 W/(m x C?) per l'Argento (Ag), circa 390 W/(in x C?) per il Rame (Cu), Quindi avremo, rispetto all 'acciaio di cui fossero ad esempio composti i dischi o i semidisehi, un guadagno di circa 1670% con il rame e circa 1850% per l'Argento, A titolo esemplificativo potrebbe trovare applicazione anche il diamante che, prescindendo dai costi, ha i valori pi? elevati di coefficiente di conduzione termica (tra 1000 ? 2600 W/(m x C?)). Va poi considerato che i diversi materiali hanno un diverso coefficiente di dilatazione termica :Cu ? 17 * 10?-6 1 Acciaio = 11 * 10? -6 1 Cp,. Quindi il rame ha un coefficiente di dilatazione termica, superiore del 50% ri spello all'acciaio. Di questo andr? tenuto conto nel posizionamento dei materiali, prevedendo un collegamento non solidale. The conductivity thermal, expressed in W / (m x C?) in Watts / meters x Celsius? between 36? 61 for steels pi? or less tied, while? of about 420 W / (m x C?) for the Silver (Ag), about 390 W / (in x C?) for the Copper (Cu). or the semidisehi, a gain of about 1670% with the copper and about 1850% for the Silver. high coefficient of thermal conduction (between 1000? 2600 W / (m x C?)). It should also be considered that the different materials have a different coefficient of thermal expansion: Cu? 17 * 10? -6 1 Steel = 11 * 10? -6 1 Cp ,. Therefore copper has a thermal expansion coefficient, 50% higher than steel. Of this will you go? taken into account in the positioning of the materials, providing for a non-integral connection.
Appare evidente che l'inserinnento di elementi opportunamente sagomati e dimensionati, dimensioni e sagome che tengano ne! debito conto i diversi coefficienti di dilatazione dei materiali, posti nel disco o tra i due semidischi di un disco ventilalo, nella pastiglia, nella pinza o in tutti i componenti suddetti c composti detti elementi ad esempio di Argento o Rame o di una lega di questi metalli, in particolare se posti nel flusso di aria che il disco ventilato genera nella sua rotazione, abbia un effetto nettamente positivo nella dissipazione del calore generalo nella azione di frenata sia per il notevole guadagno in conducibilit? termica del finsi eme, che per un ulteriore aumento della superficie radiante, Questo e altri scopi, che saranno pi? chiari in seguilo, sono raggiunti con un freno a disco comprendente almeno? un disco vincolato all'elemento in rotazione da frenare, ed almeno una corrispondente pastiglia di frenaggio atta ad agire in strisciamento relativo sul disco. La peculiarit? del freno risiede nel fatto che il disco o la pastiglia o la pinza o tutti i suddetti componenti il sistema frenante prevedono l'inserimento di materiale ad alta conducibilit? termica. It is evident that the insertion of suitably shaped and dimensioned elements, dimensions and shapes that hold the due account of the different coefficients of expansion of the materials, placed in the disc or between the two semi-discs of a ventilated disc, in the pad, in the caliper or in all the aforementioned components composed of said elements, for example of Silver or Copper or an alloy of these metals, in particular if placed in the flow of air that the ventilated disc generates in its rotation, has a clearly positive effect in the dissipation of the heat generated in the braking action both for the considerable gain in conductivity? thermal of the finsi heme, which for a further increase in the radiating surface, This and other purposes, which will be more? clear in follow it, are achieved with a disc brake comprising at least? a disk constrained to the rotating element to be braked, and at least one corresponding braking pad able to act in relative sliding on the disk. The peculiarity? of the brake lies in the fact that the disc or the pad or the caliper or all the aforementioned components of the braking system provide for the insertion of material with high conductivity? thermal.
