    摘要: 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).

The drive unit is connected to a gear set (1, 3). A first hydraulic accumulator (53) for accumulating pressure energy can be connected to one of the working lines (19, 21). A second hydraulic accumulator (55) can be connected to the other working line (19, 21). A valve device (V1, V2) permits the segment (23, 25) of each working line (19 or 21) extending to the drive unit (7) to be separated to separate an accumulator part (33) from the part of the circuit with the hydraulic pump (13). The accumulator part includes the hydraulic accumulators (53, 55) and at least one drive unit.
