Oil return path structure of electric wheel

The utility model discloses an electric wheel oil return path structure which comprises a gear box, a sun gear cavity is arranged in the gear box, the sun gear cavity is communicated with a plurality of planetary gear cavities located on the periphery of the sun gear cavity, and each planetary gear cavity is connected with a funnel-shaped collector. First oil collecting grooves are symmetrically formed in the gear box and located in the two sides of the first planetary gear cavity. Second oil collecting grooves are symmetrically formed in the gear box and located below the first oil collecting grooves, a second planetary gear cavity is formed below one second oil collecting groove, and a third planetary gear cavity is formed below the other second oil collecting groove. According to the lubricating device, splashing lubricating oil is locally collected through the funnel-shaped collector and the oil collecting groove, so that the lubricating oil enters the associated position of the bearing and the planetary
