[0002] The transmission series, especially the hybrid transmission, due to the complex arrangement of the gear shaft and the high requirement of gear shaft lubrication, the lubrication system not only needs to lubricate more gear shafts, but also needs to strictly control the lubricating oil amount of each gear shaft. Too much gear shaft oil will cause too much lubricating oil to hinder the movement of the gear shaft and increase the mechanical transmission loss. Too little gear shaft lubricating oil will cause the bearing to run at a high temperature and the bearing to fail. Therefore, an oil guide cover needs to be set on the gearbox end cover to accurately guide the lubricating oil to the bearing for lubrication.
