恩,效率比液力变矩器还低,但是油耗节省20%,我的解释很清楚了,你来解释一下吧。
我的观点也很明白
1.从现在的资料来看无论数据还是结构都看不到任何nb之处。
2.卖的便宜并不能说明技术nb,byd品牌说的很清楚了。
3.丰田的那一套系统比byd这个强太多了,定价多少是商业策略问题,在混动领域,就算这样定价和产品,也甩出第二名10条街,没有市场压力推出比竞争对手强太多了产品。
4.中国人做的东西就是好!是中国人都来顶啊!
【 在 kire 的大作中提到: 】
: In 2006 and 2007, a further development of the HSD drivetrain, under the Lexus Hybrid Drive name, was applied on the Lexus GS 450h / LS 600h sedans. This system uses two clutches (or brakes) to switch the second motor's gear ratio to the wheels between a ratio of 3.9 and 1.9, for low and high speed driving regimes respectively. This decreases the power flowing from MG1 to MG2 (or vice versa) during higher speeds. The electrical path is only about 70% efficient, thus decreasing its power flow while increasing the overall performance of the transmission.
: 刚刚去wiki查了一下,大意就说gs,ls上加了两离合,去改变mg2的驱动齿比,这样减少高速时mg1 to mg2的动力流,mg1 to mg2的电力转换效率之有70%左右,因此能更有效提高总体表现
: 嗯,这玩艺只有gs450,ls600,不知道你那个95%的比率从哪里来,来个引文看看
