Abstract

ELEMENTO DE TRANSMISSÃO DE RELAÇÃO VARIÁVEL DA INVENÇÃO COMPREENDENDO UM CORPO (1) EM FORMA DE DISCO POSSUINDO DUAS FACES, ESTANDO UMA DAS FACES DIVIDIDA EM, PELO MENOS,TRÊS SECTORES (6) CIRCULARES IGUAIS, SENDO CADA SECTOR (6) CIRCULAR DELIMITADO POR UM ARCO (7) DE CÍRCULO E POR DOIS RAIOS (8) DEFININDO ENTRE SI UM ÂNGULO (ALFA) CENTRAL. CADA SECTOR (6) POSSUI REENTRÂNCIAS (9) ALONGADAS E PARALELAS, RECORTADAS NA FACE DO CORPO (1) E DEFININDO SEGMENTOS (10) DE ENGRENAMENTO; CADA SEGMENTO (10) ESTENDE-SE DESDE O ARCO (7) DE CÍRCULO ATÉ AO RESPECTIVO RAIO (8) MAIS PRÓXIMO E FORMANDO UM ÂNGULO (ß) COM ESTE ÚLTIMO IGUAL A METADE DO ÂNGULO (ALFA). A INVENÇÃO REFERE-SE AINDA A UM SISTEMA DE TRANSMISSÃO COMPREENDENDO O ELEMENTO DE TRANSMISSÃO. A INVENÇÃO APLICA-SE À INDÚSTRIA DOS DISPOSITIVOS E VEÍCULOS MOTORIZADOS E À INDÚSTRIA DOS VEÍCULOS A PEDAL.VARIABLE RELAY TRANSMISSION ELEMENT OF THE INVENTION COMPREHENSING A BODY (1) IN DISC FORM OF TWO FACES, ONE OF THE FACES IS DIVIDED IN AT LEAST THREE SECTORS (6) EQUAL CIRCULARS, BEING EACH CIRCULAR SECTOR (6) DELIMITED BY A ARC (7) OF CIRCLE AND TWO RAYS (8) DEFINING BETWEEN A CENTRAL ANGLE (ALPHA). EACH SECTOR (6) HAS HANGED AND PARALLELED REINFORCEMENT (9) REINFORCED ON THE FACE OF THE BODY (1) AND DEFINING GEAR SEGMENTS (10); EACH SEGMENT (10) EXTENDS FROM ARC (7) OF CIRCLE TO THEIR RESPECTIVE RAY (8) NEAREST AND FORMING AN ANGLE (ß) WITH THIS LAST EQUAL TO HALF THE ANGLE (ALPHA). The invention further relates to a transmission system comprising the transmission element. THE INVENTION APPLIES TO THE INDUSTRY OF DEVICES AND MOTORIZED VEHICLES AND THE INDUSTRY OF VEHICLES TO PEDAL.
