    • In some embodiments, the present invention provides methods of making graphene-carbon nanotube hybrid materials. In some embodiments, such methods generally include: (1) associating a graphene film with a substrate; (2) applying a catalyst and a carbon source to the graphene film; and (3) growing carbon nanotubes on the graphene film. In some embodiments, the grown carbon nanotubes become covalently linked to the graphene film through carbon-carbon bonds that are located at one or more junctions between the carbon nanotubes and the graphene film. In some embodiments, the grown carbon nanotubes are in ohmic contact with the graphene film through the carbon-carbon bonds at the one or more junctions. In some embodiments, the one or more junctions may include seven-membered carbon rings. Additional embodiments of the present invention pertain to graphene-carbon nanotube hybrid materials that are formed in accordance with the methods of the present invention.

    • A transmission includes an input shaft (IP), an output shaft (OP), a single planetary gearset (SP), a compound planetary gearset (CP), shifting elements. The single planetary gearset is arranged before the compound planetary gearset, and the shifting elements comprise at least two brakes (B1,B2), the first clutch (C1), the second clutch (C2), the third clutch (C3), and all the shifting elements are positioned between the single planetary gearset and the compound planetary gearset, which has compact arrangements, and can reduce the power transmission length. The transmission also includes an one-way clutch (OWC) acted on the compound planetary gearset. When the transmission shifts to the first speed stage, the first clutch (C1) and the one-way clutch are operated, and the power is transferred from the input shaft to the output shaft via the single planetary gearset and the compound planetary gearset, and when the first speed stage is shifted to the second speed stage, only the first brake (B1) should be operated to engage, thereby it can reduce the frequency of operating the shifting elements and the shifting time in low speed stage.
    • 变速器包括输入轴(IP),输出轴(OP),单个行星齿轮组(SP),复合行星齿轮组(CP),变速元件。 单个行星齿轮组布置在复合行星齿轮组之前,变速元件包括至少两个制动器(B1,B2),第一离合器(C1),第二离合器(C2),第三离合器(C3)和所有 移动元件位于单个行星齿轮组和复合行星齿轮组之间,其具有紧凑的布置,并且可以降低动力传递长度。 变速器还包括作用在复合行星齿轮组上的单向离合器(OWC)。 当变速器移动到第一速度档时,第一离合器(C1)和单向离合器被操作,并且动力通过单个行星齿轮组和复合行星齿轮组从输入轴传递到输出轴,并且 当第一速度档位移动到第二速度档时,只有第一制动器(B1)应该被操作以啮合,从而可以降低在低速档中操作变速元件的频率和移动时间。
