【海外新訊】世界首見具備手排齒輪的CVT變速箱! Toyota發表TNGA專用科技
Toyota在今日發表了一系列專為新世代TNGA車型所研發的新科技,其中最受人矚目的便是
世界首見加入齒輪構造的CVT變速箱。在起步等需要大扭力的時候是以齒輪驅動車輛,待
速度抬升後則可切換為鋼帶傳動回復為傳統的CVT變速箱。

這具名為「Direct Shift-CVT」的變速箱基本架構仍為CVT,不過卻加入了與手排變速箱
相同的齒輪結構,在起步時利用齒輪驅動帶來更直接的傳輸效率,至於在高速時則切換為
鋼帶驅動。由於鋼帶部分不需負擔起步時的大扭力的與高齒比等需求,因此可縮減大小兩
個普利盤的尺寸以及重量,鋼帶中央的夾角也能予以縮小,這些改變則讓變速反應增加
20%以上,燃油效率較也現有的CVT變速箱增進了6%之多。

真的量產的話還蠻令人期待的
穩定度如何也值得關注
