The invention discloses an oil-lubricated commercial vehicle hub ventilation plug with ventilation and waterproof functions. The oil-lubricated commercial vehicle hub ventilation plug comprises a base with a through channel in the middle, one end of the through channel in the base is connected with a ventilation pipe, the other end of the through channel in the base is connected with a ventilation valve, and a dust cover is arranged outside the ventilation valve. And an oil-gas channel for communicating an outlet of the vent valve with the outside is arranged between the dust cover and the vent valve. A hub comprises an axle, a hub body axially arranged on the axle in a sleeving mode and an end cover arranged at the outer end of the hub body in a sleeving mode, the hub body is provided with the oil-lubricated commercial vehicle hub ventilation plug with the ventilation and waterproof functions, the base is fixedly connected with the hub body, and one end, connected with the ventilation pipe, of the base extends into an oil cavity between the hub body and the axle. The outlet end of the oil-gas channel is connected with the outer side of the hub body. The exhaust system structure of the hub is optimized, oil and gas leakage is effectively reduced, the number of hub parts is reduced, meanwhile, the dustproof and waterproof effects are achieved, and it can be guaranteed that the outer surface of the vehicle end is clean.
