Abstract

The suspension spring is formed as a flat blade spring. Section I is a straight section, formed at an angle of 20 degrees (2) to the base section. Section III is also a straight section formed at an angle of 35 degrees to the base section. Section 4 is a curved section, formed with a radius of 18 mm. It forms the angle of 35 degrees and lies between sections III and V. Section V is a straight section and forms the base line, from which all the angles are measured. Section VI is a curved section, lying between sections V and VII and forming an angle of 10 degrees between these two sections. Section VII is a straight section and Section IX is the final section, which forms an angle of 45 degrees with Section VII.

Description

L'INVENTION CONCERNE L'ADAPTATION D'UN OU PLUSTEUPS RESSORTS, EN
FORME DE G , EN MATERIEZ FERREUX OU COMPOSITE, CREVANT UN SYSTEME DE SUSPEN
SION COMPENSEEFREINEE AVEC ACTION DOUBLE DIFFEREE LORS DE LA MISE EN CHARGE. THE INVENTION CONCERNS THE ADAPTATION OF ONE OR MORE SPRINGS, IN
G-FORM, OF FERROUS OR COMPOSITE MATERIAL, PUNCHING A SUSPEN SYSTEM
COMPENSEEFREINEE SION WITH DELAYED DOUBLE ACTION DURING LOADING.

LE SYSTEME MECANIQUE PRESENTE CONCERNE UN MODE DE SUSPENSION POUR MA
TERIEL ROULANT APPLICABLE A DIVERS MATERNELS AUTONOMES TRACTES OU NON.THE MECHANICAL SYSTEM PRESENT CONCERNS A SUSPENSION MODE FOR MY
ROLLING TERIEL APPLICABLE TO VARIOUS SELF-CONTAINED TOWERS OR NOT.

CE SYSTEME PEUT NOTAMMENT ETRE ADAPTE SUR UNE BROUETTE OU UNE REMORQUE,
AU NIVEAU DE LA TRANSMISSION DES CHARGES PAR LA OU LES ROUES.THIS SYSTEM MAY PARTICULARLY BE ADAPTED ON A WHEELBAR OR A TRAILER,
AT THE LEVEL OF THE TRANSMISSION OF LOADS BY THE WHEEL (S).

DANS LE CAS DE LA BROUETTE, L'ORGANE MOTEUR DU DEPLACEMENT EST L'ETRE
HUMAIN. IL ENCAISSE LA TOTALTTE DES EFFORTS TRANSMIS PAR LA ROUE LORS DU TRANS
PORT DES CHARGES ET DES CHOCS,DÛ NOTAMMENT A L'ETAT DU TERRAIN (CAILLOUX, DENI
VELES, ETC...).IN THE CASE OF THE WHEELBAR, THE DRIVING MOTOR IS THE BEING
HUMAN. IT CASES THE TOTALTTE OF EFFORTS TRANSMITTED BY THE WHEEL DURING THE TRANS
CARRYING OF LOADS AND SHOCK, DUE IN PARTICULAR TO THE CONDITION OF THE GROUND (CAILLOUX, DENI
VELES, ETC ...).

COMME CHACUN LE SAINT L 'ANATOMIE HUMAINE EST PAR DEFINITION FRAGILES
COMPTE-TENU DES CADENCES ET DES EFFORTS SOUTENUS QUE NOUS LUI DEMANDONS JOURNEL
LEMENT.LIKE EVERYONE THE HOLY THE HUMAN ANATOMY IS BY DEFINITION FRAGILE
TAKING INTO ACCOUNT THE SUSTAINED CADENCIES AND EFFORTS THAT WE ASK FOR
LEMENT.

LES MUSCLES DES BRAS SONT LES PREMIERS A ENCAISSER LES VARIATIONS D'EF
FORTS TPANSMIS, ET LES VEHICULENT ENSUITE AUX ORGANES PRINCIPAUX ET EN PARTICU
LIER A LA COLONNE VERTEBRALE.THE MUSCLES OF THE ARMS ARE THE FIRST TO RECEIVE VARIATIONS IN EF
FORTS TPANSMIS, AND THEREFORE VEHICLES TO THE MAIN ORGANS AND IN PARTICULAR
LINK TO THE VERTEBRAL COLUMN.

SUIVANT LES ORGANISMES, LA REPERCUTION DES CHOCS ET A-COUPS SUCCESSIFS,
SONT SOUVENT A L'ORIGINE DES MAUX DE DOS CHEZ LE PROFESSIONNEL, COMME L'AMATEUR
PAR SUITE DE SURCHARGES OU INACOUTUMANCE A L'EFFORT DEMANDE.FOLLOWING ORGANISMS, IMPACT OF SUCCESSIVE SHOCKS AND SHOTS,
ARE OFTEN THE ORIGIN OF BACK PAIN IN THE PROFESSIONAL, LIKE THE AMATEUR
AS A RESULT OF OVERLOADS OR INACOUTUMANCE TO THE EFFORT REQUESTED.

LE DISPOSITIF PRESENTE PERMET DE MTEUX REPARTIR LES CHOCS ENCAISSES ET
DE LES TRANSMETTRE EN SOUPLESSE A L'ORGANISME; EN CREVANT UNE REPARTITION DU CHOC
ENCAISSE ET EN AUGMENTANT LE TEMPS DE DISSIPATION DE L'ENERGIE.THE DEVICE PRESENT ALLOWS FOR WHEELS TO DISTRIBUTE CASH SHOCK AND
TO TRANSMIT THEM IN FLEXIBILITY TO THE ORGANIZATION; BY CREATING A DISTRIBUTION OF SHOCK
INCREASED AND INCREASING THE TIME OF ENERGY DISSIPATION.

DEPENDING ON THE APPLICATION, THE SYSTEM IS NOT LIMITED IN NUMBERS
SPRINGS TO BE PLACED, AND IT MAY BE COMPATIBLE WITH OTHER SYSTEMS
IN ORDER TO ENSURE THE COMPLEMENTARITY OF A SUSPENSION MODE.

APPLICATION : DEUX RESSORTS IDENTIQUES SONT PLACES SOUS LES BRAS OU
PALIER DE SUPPORT D'ARBRE DE ROUE, ET REDOIVENT LES EFFORTS TRANSMIS A CELLE
CI. LES RESSORTS PEUVENT ETRE EN MATERIAU FERREUX OU COMPOSITE SUIVANT L'APPLI
CATION ENVISAGEE.APPLICATION: TWO SAME SPRINGS ARE PLACED UNDER THE ARMS OR
WHEEL SHAFT SUPPORT BEARING, AND REDUCE THE EFFORTS TRANSMITTED TO IT
THIS. THE SPRINGS MAY BE OF FERROUS OR COMPOSITE MATERIAL ACCORDING TO THE APP
CATION ENVISAGED.

LES RESSORTS AINSI POSITIONNES RECOIVENT EN PREMIER LES CHOCS ET EF
FORTS DE ROULEMENT NECESSAIRES AU DEPLACEMENT DES CHARGES TRANSPORTEES. LEUR
ROLE EST EN PREMIER UN ROLE D'AMORTISSEUR AVANT DE RESTITUER L'ENERGIE ENCAIS
SEE PAR L'ALLONGEMENT DU TEMPS D'ABSORPTION D'OU UN CONFORT APPRECIABLE DU
TRAVAIL DEMANDE.THE SPRINGS SO POSITIONED RECEIVE FIRST SHOCK AND EF
BEARING STRENGTHS NECESSARY FOR MOVING TRANSPORTED LOADS. THEIR
ROLE IS FIRST A SHOCK ABSORBER BEFORE RESTORING ENCAIS ENERGY
SEE BY EXTENDING THE ABSORPTION TIME OR AN APPRECIABLE COMFORT OF THE
REQUIRED WORK.

LA POSITION DES RESSORTS, EN CONTACT DIRECT AVEC L'ORIGINE DES CHOCS
SUCCESSIFS ET LEUP. PROXIMITE DU POINT D'APPUI, PERMET AINSI DE LES ABSORBER A
L'ORIGINE EN EVITANT L 'AMPLIFICATION DES PHENOMENES VIBRATOIRES.THE POSITION OF THE SPRINGS, IN DIRECT CONTACT WITH THE ORIGIN OF THE SHOCKS
SUCCESSIVE AND LEUP. NEAR THE SUPPORT POINT, ALLOWS TO ABSORB THEM AT
THE ORIGIN AVOIDING THE AMPLIFICATION OF VIBRATORY PHENOMENES.
