| 摘要 |
The invention relates to a rail vehicle drive comprising an internal combustion engine (1), a traction transmission (2), and a reversing gear (14) for driving a set of wheels of the rail vehicle. The invention is characterised in that the output side (6.1, 6.2) of the traction transmission is at least indirectly connected to a hydrostatic brake and drive unit (7) comprising at least one clutch (8), an at least two-stage transmission (9), a hydrostatic variable displacement motor/pump unit (11), a valve unit (12), and an accumulator unit for the working medium, provided with a low-pressure accumulator (14) and a high-pressure accumulator (15). Said hydrostatic brake and drive unit can be connected to the output side of the traction transmission by means of the clutch, for the braking of the rail vehicle and for the traction operation. |
