Lubricating oil conveying device for transmission device of vehicle, has conveying structure section for conveying lubricating oil in oil collection section, and another conveying structure section for supplying oil in axial direction

摘要

The lubricating oil conveying device (1) has a hollow shaft section (4) with a lubricating oil opening (12,12'), which is fluidically coupled with an annular gap (13) formed between an insert shaft section (5) and the hollow shaft section. A conveying structure section (8) is arranged in the annular gap and is designed to convey lubricating oil in a lubricating oil collection section (10). Another conveying structure section (9) is arranged in the annular gap for supplying lubricating oil in an axial direction opposite to a rotational axis (7) into the lubricating oil collection section. An independent claim is included for a transmission device with an electric motor, a transmission section and a lubricating oil conveying device for lubricating the transmission section.
