POWER TRAIN SYSTEM AND METHOD FOR OPERATING A POWER TRAIN SYSTEM

摘要

The invention relates to a method for operating a power train system (10) of a commercial vehicle (12) comprising a power train (16) mechanically driven by a drive motor (14) of the commercial vehicle (12) a connecting element for transmitting mechanical drive force from the drive motor (14) to the power train (16) and a coupling (20) for interrupting the drive force transmitted to the power train (16) via the connecting element wherein the power train system (10) further has at least one bearing (22 24 26 28 30) which is lubricated with oil by means of an oil circuit (32) in the drive motor (14). Provided according to the invention is that the coupling (20) is closed by a control signal when a period of time At lapses after the drive motor (14) is started up and/or a minimum oil pressure is present in the oil circuit (32). The invention further relates to a power train system (10).
