Pump drive assembly

摘要

The arrangement has a pump drive unit (70), which is driven by a drive device or another drive device. The pump drive unit is connected with the former drive device via a freewheel device or with the latter drive device via another freewheel device. The free-wheel devices are operated relative to a coupling unit in opposite rotary directions. The former free-wheel device is blocked if the former drive device rotates faster than the coupling unit. An independent claim is also included for a hybrid vehicle drive train with an electrical machine.
