Pump e.g. oil pump, drive arrangement for use in hybrid vehicle drive train, has pump drive unit connected with drive device via freewheel device or with another drive device via another freewheel device

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.
