    • PROBLEM TO BE SOLVED: To provide an automatic transmission which achieves multistage transmission comprising a planetary gear set having five rotational elements, three clutches and three brakes, wherein the automatic transmission can be made compact, and lighter in weight.SOLUTION: An automatic transmission 1comprises a planetary gear set PS, first to third clutches C-1 to C-3, first to third brakes B-1 to B-3, and a counter gear 100 for outputting gear-shifted rotation. The counter gear 100 is disposed to one side of the planetary gear set PS in the axial direction, and the second brake B-2 is disposed to the opposite side of the planetary gear set PS in the axial direction, with respect to the counter gear 100. The second brake B-2, which never has a higher rotation rate in comparison to the other clutches and brakes, can be disposed away from the planetary gear set PS, while the other clutches and brakes and the counter gear 100 can be disposed in proximity to the planetary gear set PS, and thicker members can be made shorter, so that more compactness, and light weight are achieved.
    • 要解决的问题:提供一种实现多级变速器的自动变速器,其包括具有五个旋转元件,三个离合器和三个制动器的行星齿轮组,其中自动变速器可以制造得紧凑,重量更轻。

      解决方案:自动变速器1 1 包括行星齿轮组PS,第一至第三离合器C-1至C-3,第一至第三制动器B-1至B -3,以及用于输出齿轮转动的中间齿轮100。 副齿轮100沿轴向配置在行星齿轮组PS的一侧,第二制动器B-2相对于副齿轮配置在行星齿轮组PS的轴向相对侧 与其他离合器和制动器相比,不具有较高转速的第二制动器B-2可以远离行星齿轮组PS设置,而另一个离合器和制动器和中间齿轮100可以被布置 靠近行星齿轮组PS,并且可以使更厚的部件更短,从而实现更紧凑和轻便。 版权所有(C)2013,JPO&INPIT
