Gra\u00e7as ao seu sistema integral de molas e amortecedores, o volante bimassa absorve certas vibra\u00e7\u00f5es de tors\u00e3o, o resultado \u00e9 um isolamento adequado das vibra\u00e7\u00f5es e um melhor funcionamento do ve\u00edculo.<\/span><\/p>\n

Por que us\u00e1-lo?<\/h4>\n

Os ciclos peri\u00f3dicos de combust\u00e3o de um motor de 4 pist\u00f5es geram vibra\u00e7\u00f5es de tors\u00e3o na cadeia cinem\u00e1tica. Os ru\u00eddos e as vibra\u00e7\u00f5es resultantes, como solavancos do c\u00e2mbio de marchas e o balan\u00e7o da carroceria tem como consequ\u00eancia uma perda do conforto ac\u00fastico e de comodidade na condu\u00e7\u00e3o. Por isso, o desenvolvimento do volante bimassa,\u00a0buscando isolar do restante da cadeia cinem\u00e1tica as vibra\u00e7\u00f5es de tors\u00e3o geradas pela massa girat\u00f3ria do motor.<\/span><\/p>\n

Como \u00e9 composto?<\/h4>\n

Um volante bimassa padr\u00e3o consta de uma massa prim\u00e1ria e uma massa secund\u00e1ria. Desacopladas est\u00e3o conectadas entre si por um sistema de molas\/amortecedores e est\u00e3o alojadas de forma girat\u00f3ria uma contra a outra por meio de um rolamento de esferas com profundo sulco ou uma bucha de fric\u00e7\u00e3o. A massa prim\u00e1ria com coroa de arranque est\u00e1 definida ao motor e fi e parafusada ao virabrequim. Juntamente com a tampa prim\u00e1ria, circunda um espa\u00e7o oco que forma o canal de mola de arco. A massa secund\u00e1ria ajuda a aumentar o momento de in\u00e9rcia do lado da caixa de c\u00e2mbio.<\/p>\n

\"\"<\/a><\/p>\n

Como funciona?<\/h4>\n

O sistema de molas-amortecedores \u00e9 composto das molas do arco, que est\u00e3o nas guias nos canais das molas de arco e cumprem com os requisitos de um amortecedor de tors\u00e3o
\n\u201cideal\u201d com um trabalho m\u00ednimo. As guias garantem um posicionamento correto das molas durante o funcionamento, e a graxa entre as molas reduz o desgaste entre elas, as
\n<\/span>guias e os canais. O par \u00e9 transferido por meio do flange. O flange est\u00e1 rebitado \u00e0 massa secund\u00e1ria, com suas abas inseridas entre as molas do arco. Umas fendas de ventila\u00e7\u00e3o garantem uma melhor evacua\u00e7\u00e3o do calor. Uma vez que o volante bimassa tem um sistema integral de molas-amortecedoras, normalmente se utiliza um disco de embreagem r\u00edgido sem amortecedor de tors\u00e3o. <\/span><\/p>\n

Ru\u00eddos – Diagn\u00f3stico de avarias<\/h4>\n

Sempre \u00e9 importante determinar se o ru\u00eddo \u00e9 procedente de componentes adjacentes, como o sistema de escape, as placas de prote\u00e7\u00e3o t\u00e9rmica, suportes do motor ou c\u00e2mbio, acess\u00f3rios, etc. Tamb\u00e9m \u00e9 preciso isolar qualquer ru\u00eddo causado por acess\u00f3rios frontais, como unidades tensoras de correia ou compressores do ar condicionado. Para determinar a proced\u00eancia do ru\u00eddo, pode-se usar um estetosc\u00f3pio. Caso as vibra\u00e7\u00f5es do motor aumentem ao aumentar as rota\u00e7\u00f5es, o volante bimassa est\u00e1 com defeito. Neste caso tamb\u00e9m \u00e9 recomend\u00e1vel comparar o ve\u00edculo com outro com uma motoriza\u00e7\u00e3o igual ou similar.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
