Abstract

"AMORTECEDOR". Um amortecedor dependente de freqüência incorpora um conjunto de pistão compensado para redução da quantidade de força de arrancamento estática. A haste de pistão é uma haste oca com um compensador sendo disposto na porção oca da haste de pistão. O compensador é afixado ao tubo de pressão do amortecedor, de modo que o compensador deslize na haste de pistão durante o curso do absorvedor de choque. o conjunto de pistão compensado reduz a diferença de área de seção transversal entre as superfícies superior e inferior do pistão.
