The invention discloses a wheel end active lubricating device. In the wheel end active lubricating device, an axle housing comprises a driving cavity and a connecting cavity which are communicated with each other; the wheel end part is located at the end part of the axle housing, the wheel end part comprises an oil storage cavity communicated with the connecting cavity and a speed reducing mechanism at least partially located in the oil storage cavity, and the speed reducing mechanism is connected with the half shaft extending to the driving cavity; the oil disc is arranged in the connecting cavity in a sealed mode, an inner hole is formed in the oil disc, the half shaft penetrates through the inner hole, and an oil passing gap is reserved between the half shaft and the inner hole. The oil supply part comprises an oil supply channel and a driving part which are in driving connection, an inlet of the oil supply channel is communicated with lubricating oil in the driving cavity, an outlet of the oil supply channel is communicated with the through hole in the oil disc, or the outlet of the oil supply channel is formed in the inner wall, located on the oil disc and facing the wheel end, of the connecting cavity so that oil can be supplied to the wheel end under driving of the driving part. Lubricating oil is actively provided for the wheel end, the lubricating effect of parts in the wheel end is kept, and meanwhile the problem that the temperature of the lubricating oil at the wheel end is too high is solved.
