| 摘要 |
A drive train (1) includes an internal combustion engine (2) and working hydraulics (4) having at least one hydraulic pump (7). When operated as a pump, the hydraulic pump (7) sucks hydraulic fluid from a tank (9) and delivers into a delivery line (10) that leads to the working hydraulics (4). When operated as a motor, the hydraulic pump (7) is supplied with hydraulic fluid from a hydraulic accumulator (25). The drive train (1) has a charge pump (20) to supply a charging circuit (23). The charge pump (20), when operated as a pump, sucks hydraulic fluid out of the tank (9) and delivers into a charge pressure line (22) that leads to a charging circuit (23), and the charge pump (20) when operated as a motor is supplied with hydraulic fluid from the hydraulic accumulator (25). |

1. A drive train of a vehicle, comprising:
an internal combustion engine; working hydraulics driven by the internal combustion engine, wherein the working hydraulics include at least one hydraulic pump driven by the internal combustion engine, wherein the hydraulic pump is operable as a pump and as a motor, wherein the hydraulic pump, when operated as a pump, sucks hydraulic fluid from a tank on a suction side and delivers into a delivery line that leads to the working hydraulics, and wherein the hydraulic pump, when operated as a motor, is supplied with hydraulic fluid from a hydraulic accumulator on the suction side; and a charge pump driven by the internal combustion engine to supply a charging circuit, wherein the charge pump is operable as a pump and as a motor, wherein the charge pump, when operated as a pump, sucks hydraulic fluid out of the tank on a suction side and delivers into a charge pressure line that leads to the charging circuit, and wherein the charge pump, when operated as a motor, is supplied with hydraulic fluid from the hydraulic accumulator on the suction side. |
