摘要： A gearwheel arrangement (1) for a transmission of a vehicle, such as an electric vehicle, comprising:
- a shaft (2) extending along a longitudinal axis of rotation (A), comprising an internal axial duct (3) for guiding lubricant,
- a gearwheel (4) comprising a base portion (5) centred on the shaft and a plurality of gear teeth (6) provided around a periphery of the gearwheel, the gearwheel preferably being configured for common rotation with the shaft.
The gearwheel arrangement further comprises an internal radial duct (7) for guiding lubricant from the internal axial duct to the gear teeth. The internal radial duct may extend at least in part behind a gearwheel cover (8).-
