Description

"FRENO IDRAULICO PER VEICOLI†"HYDRAULIC BRAKE FOR VEHICLES⠀

DESCRIZIONE DESCRIPTION

Il trovato in oggetto si riferisce ad un freno idraulico per veicoli, preferibilmente destinato alle moto d’epoca degli anni ’60 - 70 che montavano freni a tamburo. Questo nuovo freno, infatti, abbina Se caratteristiche estetiche di un freno a tamburo tipico di quegli anni alle prestazioni superiori di un freno moderno e, nello specifico, di un freno a doppio disco funzionante idraulicamente. The invention in question refers to a hydraulic brake for vehicles, preferably intended for vintage motorbikes of the 60s - 70s which were fitted with drum brakes. This new brake, in fact, combines the aesthetic characteristics of a drum brake typical of those years with the superior performance of a modern brake and, specifically, of a hydraulically operated double disc brake.

Questo nuovo freno à ̈ concepito in modo da presentare due dischi che, applicati alle due facce opposte di un tamburo calettato centralmente alla ruota, vengono frenati e arrestati dall’azione di una pluralità di elementi frenanti o “pastiglie†, azionate idraulicamente per agire contro i due dischi da una parte e dall’altra del tamburo. This new brake is conceived in such a way as to have two discs which, applied to the two opposite faces of a drum keyed centrally to the wheel, are braked and stopped by the action of a plurality of braking elements or `` pads '', hydraulically operated for act against the two discs on both sides of the drum.

In tal modo concepito, il freno risulta sprovvisto di quelle masse giroscopiche eccentriche proprie dei freni a disco tradizionali, che influiscono negativamente sulla tenuta della moto soprattutto in caso di frenata in curva o sul bagnato. Conceived in this way, the brake is devoid of those eccentric gyroscopic masses typical of traditional disc brakes, which negatively affect the grip of the motorcycle, especially when braking in curves or in the wet.

Queste ed altre caratteristiche del nuovo freno ideato sono di seguito descritte con l'ausilio di quattro tavole di disegno dove, a solo titolo indicativo e non limitativo, sono rappresentate: These and other characteristics of the new brake designed are described below with the aid of four drawing tables where, for information only and not limitative, are represented:

- le FIGG. 1 e 2 che mostrano, rispettivamente, la vista frontale e la sezione verticale del freno in oggetto; - FIGS. 1 and 2 which show, respectively, the front view and the vertical section of the brake in question;

- le FIGG. 3 e 4 che mostrano, rispettivamente, la vista frontale e la sezione verticale de! tamburo de! freno in oggetto; - FIGS. 3 and 4 which show, respectively, the front view and the vertical section of drum de! brake in question;

- le FIGG. 5 e 6 che mostrano, rispettivamente, la vista frontale e la sezione verticale di uno dei dischi del freno in oggetto; - FIGS. 5 and 6 which show, respectively, the front view and the vertical section of one of the brake discs in question;

- le FIGG. 7 e 8 che mostrano, rispettivamente, la vista frontale e la sezione verticale de! mozzo del freno in oggetto; - FIGS. 7 and 8 which show, respectively, the front view and the vertical section of brake hub in question;

- le FIGG. 9, 10 e 11 che mostrano, rispettivamente, la vista frontale esterna, una sezione verticale e la vista frontale interna del coperchio del freno in oggetto. - FIGS. 9, 10 and 11 which show, respectively, the external front view, a vertical section and the internal front view of the brake cover in question.

Dall’esame dei disegni allegati ed iniziando dalle FIGG. 1, 2, 3 e 4, si evince che il freno idraulico in oggetto comprende un tamburo centrale 1 che, coassiale al pneumatico mediante un mozzo 3 provvisto di appositi cuscinetti 6 posizionati nelle sedi 3A ed applicato all’albero della ruota, presenta centralmente una corona circolare di fori 1A, filettati e passanti per poter fissare, su ciascuna faccia del tamburo stesso, un disco metallico 4, di acciaio o ghisa. Detti dischi 4, FIGG. 5 e 6, sono a loro volta provvisti di una corrispondente corona di fori passanti 4A per essere fissati al tamburo 1 e quindi ruotare con esso solidalmente alla ruota 2. From the examination of the attached drawings and starting from FIGS. 1, 2, 3 and 4, it can be seen that the hydraulic brake in question comprises a central drum 1 which, coaxial to the tire by means of a hub 3 provided with special bearings 6 positioned in the seats 3A and applied to the wheel shaft, has a central a circular ring of holes 1A, threaded and passing through in order to be able to fix, on each face of the drum itself, a metal disc 4, made of steel or cast iron. Said discs 4, FIGS. 5 and 6, are in turn provided with a corresponding ring of through holes 4A to be fixed to the drum 1 and then rotate with it integrally with the wheel 2.

Due coperchi 5, FIGG. 9, 10 e 11, chiudono da entrambe le parti il tamburo 1 con i dischi 4, essendo detti coperchi 5 fissati, mediante bulloni impegnati nei fori 5A, al mozzo centrale 3 provvisto di corrispondenti fori 3B. Two lids 5, FIGS. 9, 10 and 11, close the drum 1 with the discs 4 on both sides, said covers 5 being fixed, by means of bolts engaged in the holes 5A, to the central hub 3 provided with corresponding holes 3B.

Ogni coperchio 5 à ̈ provvisto internamente di tre camere cilindriche 5B che, posizionate a 120°, sono destinate ad ospitare all’interno altrettante "pastiglie†di materiale d’attrito o elementi frenanti. Il comando dì dette pastiglie à ̈ idraulico ed infatti prevede un piccolo cilindro montato sul manubrio della moto ed un pistone, comandato dalla leva del freno, che scivola in un contenitore pieno di apposito liquido od olio ad altissima temperatura di ebollizione. Un condotto C, tratteggiato nelle FIGG. 9 e 11, mette in comunicazione questo cilindro con una delle tre camere di ogni coperchio 5 e, precisamente, quella provvista del foro 5C di ingresso dell'olio, avente asse pressoché parallelo all’asse del coperchio 5. Questa camera di ingresso dell’olio à ̈ collegata alle altre due mediante due condotti 7 che, tratteggiati in FIG. 9, sono applicati in appositi fori 5D realizzati sulla superficie laterale delle stesse camere 5B, ciò consentendo così di riempirle in successione. In corrispondenza dell'ultima camera 5B in ordine di riempimento, à ̈ realizzato un foro 5E per la fuoriuscita dell’aria all’atto dell’ingresso dell'olio nelle camere. Per rendere ottimale detto afflusso di olio e facilitare detta uscita dell’arìa, i due coperchi 5 sono montati entrambi con i fori 5C di ingresso dell’olio stabilmente posizionati in basso e con i fori 5E di spurgo dell’aria stabilmente posizionati in alto, come in FIG. 1. Each cover 5 is internally provided with three cylindrical chambers 5B which, positioned at 120 °, are designed to house as many "pads" of friction material or braking elements inside. The control of these pads is hydraulic and in fact it foresees a small cylinder mounted on the handlebar of the motorcycle and a piston, controlled by the brake lever, which slides into a container full of special liquid or oil at very high boiling temperature. A duct C, dashed in Figures 9 and 11, connects this cylinder with one of the three chambers of each cover 5 and, precisely, the one provided with the oil inlet hole 5C, having an axis almost parallel to the axis of the cover 5. This oil inlet chamber It is connected to the other two by two ducts 7 which, dashed in FIG. 9, are applied in special holes 5D made on the lateral surface of the chambers 5B, thus allowing them to be filled in succession. assignment. In correspondence with the last chamber 5B in order of filling, a hole 5E is made for the air to escape when the oil enters the chambers. To optimize said oil inflow and facilitate said air outlet, the two covers 5 are both mounted with the oil inlet holes 5C firmly positioned at the bottom and with the air bleed holes 5E stably positioned at the top, as in FIG. 1.

All’atto dell’azionamento della leva del freno, l’ingresso dell’olio nelle tre camere 5B di ogni coperchio 5 determina lo spostamento di corrispondenti pistoncini alloggiati in ciascuna camera 5B che spingono le relative pastiglie frenanti contro il corrispondente disco 4, in tal modo rallentandolo e, se necessario, arrestandone completamente la rotazione. When the brake lever is operated, the entry of oil into the three chambers 5B of each cover 5 causes the displacement of corresponding pistons housed in each chamber 5B which push the relative brake pads against the corresponding disc 4, thus slowing it down and, if necessary, completely stopping its rotation.

Per consentire il raffreddamento del freno, un’apertura 5F provvista di grata à ̈ realizzata sulla superficie laterale del coperchio 5 mentre quattro ulteriori aperture 5G provviste di grate, nella fattispecie circolari, sono realizzate sul coperchio 5 da parte opposta alla grata 5F; all’atto del montaggio dei coperchi 5, le grate 5F sono posizionate rivolte nel senso di marcia per consentire l'ingresso dell'aria che, dopo aver lambito i dischi 4, fuoriesce dalle suddette grate circolari 5G. To allow the brake to cool down, an opening 5F provided with a grate is made on the lateral surface of the cover 5 while four further openings 5G provided with grates, in this case circular, are made on the cover 5 on the opposite side to the grate 5F; upon assembly of the covers 5, the grates 5F are positioned facing in the direction of travel to allow the entry of air which, after having licked the discs 4, escapes from the aforementioned circular grates 5G.

Un ulteriore foro 5H, cieco e realizzato sulla superficie esterna de! coperchio 5, consente il collegamento con le aste dello sterzo del motore, nella maniera tipica delle moto d'epoca. A further hole 5H, blind and made on the external surface of the cover 5, allows the connection with the steering rods of the engine, in the typical manner of vintage motorcycles.

Resta infine da aggiungere che, ferme restando le caratteristiche di massima illustrate e descritte, il freno ideato potrà essere suscettibile dì modifiche o varianti comunque comprese nel presente ambito brevettale e che potrebbero ad esempio riguardare differenti dimensionamenti del freno stesso a seconda dell’applicazione prevista, che potrebbe avvenire non solo su motociclette ma anche su autovetture. Finally, it remains to add that, without prejudice to the general characteristics illustrated and described, the brake conceived may be susceptible to modifications or variations in any case included in the present patent scope and which could, for example, concern different dimensions of the brake itself depending on the application. expected, which could occur not only on motorcycles but also on cars.
