    • A hydrostatic hybrid drive system for road vehicles includes a pump/motor unit (1) connected to the powertrain of the vehicle, controlled by a control unit (5) in a pump or motor operation, and connected to a high-pressure hydraulic accumulator via a first working line (7). The first working line can be closed by a control valve (45) and connected to a low-pressure hydraulic accumulator via a second working line (9). The high-pressure hydraulic accumulator and low-pressure hydraulic accumulator are formed by a double-piston accumulator (11), in which a high-pressure side and a low-pressure side having respective accumulator pistons (15, 17) are formed in an accumulator housing (13). The fluid chambers (23, 25) of the high-pressure side and the low-pressure side are separated by a central housing part (21) through which the common piston rod for both accumulator pistons (15, 17) extends. The control unit (5) of the pump/motor unit (1) having a control area can be supplied from the first working line (7) via a line connection (59) provided on the first working line (7) between the pump/motor unit (1) and the control valve (45).
    • 用于道路车辆的静液压混合动力驱动系统包括连接到车辆的动力系的泵/马达单元(1),由泵或马达操作中的控制单元(5)控制,并连接到高压液压蓄能器 第一条工作线(7)。 第一工作线可以由控制阀(45)关闭,并通过第二工作线(9)连接到低压液压蓄能器。 高压液压蓄能器和低压液压蓄能器由双活塞蓄能器(11)形成,其中具有各自的蓄能器活塞(15,17)的高压侧和低压侧形成在 蓄能器壳体(13)。 高压侧和低压侧的流体室(23,25)由中心壳体部分(21)分开,用于两个蓄能器活塞(15,17)的公共活塞杆通过该中心壳体部分延伸。 具有控制区域的泵/马达单元(1)的控制单元(5)可以经由设置在第一工作管线(7)上的线路连接(59)从第一工作线(7)供给到泵/ 马达单元(1)和控制阀(45)。

    • 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。
