SOSPENSIONE A BIELLE SUSPENSION WITH CONNECTING RODS

DESCRIZIONE DEL SISTEMA SYSTEM DESCRIPTION

Trattasi di sistema di sospensione della ruota anteriore dei motocicli (avantreno) per mezzo di una serie di bielle (3-4-5 per lato) (dis. N°1) in sostituzione della tradizionale forcella telescopica a steli, le bielle sono unite tra loro alle teste per mezzo di cuscinetti che consentono un'oscillazione tra le bielle stesse (dis. N°2) quest'oscillazione e' gestita tramite appositi ancoraggi posti in modo disassato rispetto all 'oscillazione delle bielle stesse (dis. N°3) mediante dei tiranti, che trasferiscono il movimento all'estremità' opposta degli stessi, questi sono fissati ad ammortizzatori che permettono il funzionamento della sospensione (dis.n°4). I tiranti, potranno essere; a cordina con guaina guida (dis. N°5) che con sistema idraulico per mezzo di pistoni collegati da tubo idraulico flessibile (dis n°6). L'insieme degli elementi risulta come da allegato (dis. N°7) la serie di bielle e' posta su entrambi i lati della ruota, solo i primi componenti in alto del sistema non sono delle bielle ma due tubi piegati ad "L" (dis.n°8) per consentire il montaggio su attacchi piastre This is a suspension system for the front wheel of motorcycles (front end) by means of a series of connecting rods (3-4-5 per side) (dis. N ° 1) in place of the traditional telescopic fork with stems, the connecting rods are joined between them to the heads by means of bearings that allow an oscillation between the connecting rods themselves (dis. N ° 2) this oscillation is managed by means of special anchors placed off-axis with respect to the oscillation of the connecting rods themselves (dis. N ° 3) by means of tie rods, which transfer the movement to the opposite end of the same, these are fixed to shock absorbers that allow the suspension to function (drawing n ° 4). The tie rods could be; cord with guide sheath (dis. N ° 5) and with hydraulic system by means of pistons connected by flexible hydraulic hose (dis. 6). The set of elements is as per attachment (drawing N ° 7) the series of connecting rods is placed on both sides of the wheel, only the first components at the top of the system are not connecting rods but two "L" bent tubes (drawing n ° 8) to allow mounting on plate attachments

SOSPENSIONE A BIELLE SUSPENSION WITH CONNECTING RODS

QUALI PROBLEMI RISOLVE WHAT PROBLEMS IT SOLVES

IL SISTEMA DI SOSPENSIONE "TRADIZIONALE" A FORCELLE CON STELI TELESCOPICI, HA IL LIMITE DELL'ESCURSIONE LEGATO ALLA LUNGHEZZA DELLA FORCELLA STESSA, THE "TRADITIONAL" SUSPENSION SYSTEM WITH FORKS WITH TELESCOPIC STEMS, HAS THE LIMIT OF THE EXCURSION LINKED TO THE LENGTH OF THE FORK ITSELF,

IL SISTEMA A BIELLE PERMETTE DI GESTIRE LA LUNGHEZZA DELL'ESCURSIONE FINO A RADDOPPIARLA AL CONFRONTO DI QUELLA TRADIZIONALE THE CONNECTING ROD SYSTEM ALLOWS TO MANAGE THE LENGTH OF THE EXCURSION UP TO DOUBLE IT COMPARED WITH THE TRADITIONAL ONE

IL SISTEMA DI SOSPENSIONE "TRADIZIONALE" A FORCELLE CON STELI TELESCOPICI HA IL PROBLEMA DELL' AFFONDAMENTO IN FRENATA IL SISTEMA A BIELLE PERMETTE DI EVITARE THE "TRADITIONAL" SUSPENSION SYSTEM WITH FORKS WITH TELESCOPIC STEMS HAS THE PROBLEM OF SINKING IN BRAKING THE CONNECTING SYSTEM ALLOWS TO AVOID

L'AFFONDAMENTO IN FRENATA SINKING IN BRAKING

IL SISTEMA DI SOSPENSIONE "TRADIZIONALE" A FORCELLE CON STELI TELESCOPICI HA IL PROBLEMA DEL PESO, (8/9 KG.) THE "TRADITIONAL" SUSPENSION SYSTEM WITH FORKS WITH TELESCOPIC STEMS HAS THE PROBLEM OF THE WEIGHT, (8/9 KG.)

IL SISTEMA A BIELLE PESA CIRCA IL 50% MENO DI UN SISTEMA TRADIZIONALE, CON L'UTILIZZO DI MATERIALI SPECIALI SCENDERE SOLO A 1/3 IL SISTEMA DI SOSPENSIONE "TRADIZIONALE" A FORCELLE CON STELI TELESCOPICI HA IL PROBLEMA DI MANTENERE TUTTA LA GESTIONE DELLE FORZE SULL'AVANTRENO THE CONNECTING ROD SYSTEM WEIGHS APPROXIMATELY 50% LESS THAN A TRADITIONAL SYSTEM, WITH THE USE OF SPECIAL MATERIALS, THE "TRADITIONAL" SUSPENSION SYSTEM WITH TELESCOPIC FORKS HAS THE PROBLEM OF KEEPING ALL FORCE MANAGEMENT TO 1/3 ON THE FRONT

(MOLLE DI SPINTA, PISTONI PER CONTROLLO RITORNO, OLIO E SERBATOI) (THRUST SPRINGS, PISTONS FOR RETURN CHECK, OIL AND TANKS)

IL SISTEMA A BIELLE PERMETTE DI DISLOCARE QUESTE FORZE OVUNQUE SULLA MOTO (ES, SOTTO SERBATOIO, SOTTO SELLA, SOTTO MOTORE, DIETRO MOTORE ) CONSENTENDO LA GESTIONE DEI PESI E LO SCARICO DELLE FORZE DOVE SI REPUTA PIU' OPPORTUNO. THE CONNECTING ROD SYSTEM ALLOWS THESE FORCES TO BE DISPLACED EVERYWHERE ON THE MOTORCYCLE (ES, UNDER THE TANK, UNDER THE SEAT, UNDER ENGINE, BEHIND ENGINE) ALLOWING THE MANAGEMENT OF WEIGHTS AND UNLOADING THE FORCES WHERE IT IS MOST APPROPRIATE.

SOSPENSIONE A BIELLE SUSPENSION WITH CONNECTING RODS

COME RISOLVE I PROBLEMI HOW IT SOLVES PROBLEMS

1) PROBLEMA ESCURSIONE: 1) EXCURSION PROBLEM:

ALLUNGANDO O ACCORCIANDO LA CORDINA 0 IL PISTONE IDRAULICO DI TRASFERIMENTO FORZE, IL SISTEMA A BIELLE SI ALLUNGA 0 SI ACCORCIA OGNI BIELLA HA UN SUO TIRANTE DI CONTROLLO GESTIBILE IN MODO AUTONOMO, CIO' PERMETTE UNA GESTIONE DIVERSA DI AFFONDAMENTO E FRENATA DEL RITORNO DI OGNIUNA, L'INSIEME PERMETTE UNA GESTIONE DI TUTTO IL MOVIMENTO IMPOSSIBILE CON UN SISTEMA TRADIZIONALE. BY LENGTHENING OR SHORTENING THE CORD OR THE HYDRAULIC FORCE TRANSFER PISTON, THE CONNECTING ROD SYSTEM IS LENGTHENED OR SHORTENING EACH CONNECTING ROD HAS ITS INDEPENDENT MANAGEABLE CONTROL ROD, WHICH ALLOWS A DIFFERENT MANAGEMENT OF EVERY SINKING AND BRAKING THE ASSEMBLY ALLOWS A MANAGEMENT OF ALL THE IMPOSSIBLE MOVEMENT WITH A TRADITIONAL SYSTEM.

2) PROBLEMA AFFONDAMENTO: 2) SINKING PROBLEM:

L'ULTIMA BIELLA DEL SISTEMA, A CUI E' FISSATA LA RUOTA ANTERIORE E' RIVOLTA VERSO IL SENSO DI MARCIA, IN FRENATA LA FORZA PRODOTTA SPINGE VERSO IL BASSO APRENDO THE LAST CONNECTING ROD OF THE SYSTEM, TO WHICH THE FRONT WHEEL IS FIXED IS FACED IN THE DIRECTION OF THE RUN, WHEN BRAKING THE FORCE PRODUCED PUSHES DOWNWARDS OPENING

L'ANGOLO DEL RAGGIO DI APERTURA DELLA STESSA IN RAPPORTO A QUELLA PRECEDENTE, ALLUNGANDO L'ESCURSIONE DEL SISTEMA SI EVITA L'AFFONDAMENTO CHE NON PERMETTE UN ASSETTO COSTANTE THE ANGLE OF THE OPENING RADIUS OF THE SAME IN RELATION TO THE PREVIOUS ONE, BY EXTENDING THE EXCURSION OF THE SYSTEM YOU AVOID SINKING WHICH DOES NOT ALLOW A CONSTANT TRIM

3) PROBLEMA PESO: 3) WEIGHT PROBLEM:

TRATTANDOSI DI SOLE BIELLE PRODOTTE CON ALLUMINIO (SE IN MODO TRADIZIONALE) 0 CON MATERIALI TECNOLOGICI COMPOSITI (ES. FIBRA DI CARBONIO) CON CUSCINETTO E DI CORDINE CON GUAINA O PISTONI CON TUBO IDRAULICO IL SISTEMA NON E' GRAVATO DALLA PRESENZA NE DI MOLLE NE DI AMMORTIZZATORI NE DI SERBATOI DELL'OLIO NE DALL'OLIO STESSO, DETERMINANDO UN PESO COMPLESSIVO DALL'AVANTRENO NETTAMENTE INFERIORE DI QUELLO TRADIZIONALE THERE IS ONLY CONNECTING RODS PRODUCED WITH ALUMINUM (IF IN THE TRADITIONAL WAY) OR WITH TECHNOLOGICAL COMPOSITE MATERIALS (EX. CARBON FIBER) WITH BEARING AND CORDS WITH SHEATH OR PISTONS WITH HYDRAULIC PIPE, THE SYSTEM IS NOT HAVED BY THE PRESENCE OF SPRINGS SHOCK ABSORBERS NEITHER THE OIL TANKS OR THE OIL ITSELF, DETERMINING A TOTAL WEIGHT FROM THE FRONT TRAIN LESS THAN TRADITIONAL

4) PROBLEMA DI SCARICO DELLE FORZE: 4) FORCES RELEASE PROBLEM:

IL SISTEMA CONSENTE DI TRASFERIRE LA GESTIONE DI AFFONDAMENTO E DI RITORNO DELL'INSIEME, THE SYSTEM ALLOWS TO TRANSFER THE MANAGEMENT OF SINKING AND RETURN OF THE ASSEMBLY,

OGNI SINGOLA BIELLA E' COLLEGATA CON UNA CORDINA O PISTONE IDRAULICO ALLA CUI ESTREMITÀ' OPPOSTA E' COLLEGATO L'AMMORTIZZATORE, LA COLLOCAZIONE DELL'AMMORTIZZATORE NON E' IN ALCUN MODO VINCOLANTE IL FUNZIONAMENTO DEL SISTEMA STESSO. EVERY SINGLE CONNECTING ROD IS CONNECTED TO A HYDRAULIC CORD OR PISTON TO WHICH THE SHOCK ABSORBER IS CONNECTED TO THE OPPOSITE END, THE POSITION OF THE SHOCK ABSORBER IS NOT IN ANY WAY BINDING THE OPERATION OF THE SYSTEM ITSELF.

LA LIBERTA' DI COLLOCAZIONE DELL' AMMORTIZZATORE DETERMINA LA POSSIBILITÀ' DI GESTIRE IL BILANCIAMENTO DEI PESI THE FREEDOM OF PLACEMENT OF THE SHOCK ABSORBER DETERMINES THE POSSIBILITY OF MANAGING THE BALANCING OF WEIGHTS
