Abstract

transmissão veicular continuamente variável acionada por correia e método de controle da mesma. a presente invenção refere-se a uma transmissão veicular continuamente variável acionada por correia, a força de aperto de correia é inibida de se tornar excessiva e um fator de segurança, em relação ao deslizamento de correia, da força de aperto de correia aplicada a uma correia de transmissão (48) é reduzida a um valor que é menos que ou igual a 1,5 reduzindo uma área de recepção de pressão (s0~ out~) de um cilindro hidráulico de lado de saída (46c). como resultado, uma câmara canceladora de pressão hidráulica centrífuga em um lado de polia secundária (46) pode ser eliminada simplificando assim a estrutura da transmissão veicular continuamente variável acionada por correia, enquanto a força de aperto de correia pode ser apropriadamente controlada.
