LUBRICATING STRUCTURE OF DRIVING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a lubricating structure of a driving device which surely supplies lubricating oil into a driving device while suppressing the increases in a parts count and electric energy consumption.

SOLUTION: The driving device includes a driving motor shaft 20 for transmitting output of a driving motor 3 with a differential 11 for front wheels installed below the driving motor shaft 20. A differential lubricating oil storing part 40 is provided in the lower part of the differential case 11a covering the differential 11 for front wheels. A plurality of reduction gear pairs are provided between the driving motor shaft 20 and differential case 11a through the medium of first and second intermediate shafts 23, 27. A hydraulic pump 42 is provided in an end of the second intermediate shaft 27. The hydraulic pump 42 is driven by the rotation of the second intermediate shaft 27 to supply lubricating oil to the driving motor shaft 20 and in proximity thereof from the differential lubricating oil storing part 40.
