Abstract

"PISTãO DE EMBREAGEM LIGADO". A presente invenção refere-se a uma montagem de embreagem que inclui um primeiro elemento e um segundo elemento rotativo em relação ao primeiro elemento. Um invólucro de embreagem é proporcionado para acoplar por atrito os primeiro e segundo elementos. Uma câmara de pistão é proporcionada adjacente ao invólucro da embreagem, e um pistão é disposto na câmara do pistão e operante para aplicar pressão axial no invólucro da embreagem. O pistão inclui primeira, segunda e terceira porções de vedação moldadas integralmente no lugar no pistão e acoplando a câmara do pistão em locais espaçados. As primeira, segunda e terceira porções de vedação moldadas integralmente reduzem o número de componentes necessários para vedar adequadamente a câmara do pistão e reduzem a quantidade de mão-de-obra requerida para a montagem.
