The invention relates to a drive axle active lubrication system which comprises a reducer shell, an oil inlet channel and an oil outlet channel are formed in the reducer shell, one end of the oil inlet channel is communicated with an inner cavity of an axle shell, and the reducer shell is installed at one end of an axle shell and internally provided with an inter-axle differential mechanism. The round shell cover is installed at the end, away from the axle housing, of the reducer shell, a pump cavity and a bearing hole cavity are formed in the middle of the round shell cover, an oil suction channel and an oil discharge channel are formed in the round shell cover, one end of the oil suction channel communicates with the end, away from an inner cavity of the axle housing, of the oil inlet channel, one end of the oil discharge channel extends to the oil outlet channel, and the other end of the oil suction channel communicates to the pump cavity. The other end of the oil discharge channel is communicated to the bearing hole cavity; the driving oil pump comprises a main shaft and an internal gear pump set, the main shaft is rotatably installed in the pump cavity, the internal gear pump set is arranged in the pump cavity and is in driving connection with the main shaft, the problem that a traditional lubricating system is poor in working condition adaptability is effectively solved, the service life of an inter-axle differential mechanism is remarkably prolonged, and the operation and maintenance cost of a vehicle is effectively reduced; the invention further provides a drive axle.

    本发明涉及一种驱动桥主动润滑系统,其包括减壳,安装于桥壳的一端且内部设置有轴间差速器,减壳上形成有进油道和出油道,进油道的一端与桥壳内腔连通;圆壳盖,其安装于减壳远离桥壳的一端且中部形成有泵腔和轴承孔腔,圆壳盖上形成有吸油道和排油道,吸油道的一端与进油道远离桥壳内腔的一端连通,排油道的一端延伸至出油道,吸油道的另一端连通至泵腔,排油道的另一端连通至轴承孔腔;主动油泵,其包括主轴和内啮合齿轮泵组,主轴可转动的安装于泵腔,内啮合齿轮泵组设置于泵腔并与主轴驱动连接,其有效的解决了传统润滑系统工况适应性差的问题,显著提高了轴间差速器使用寿命,有效降低车辆运营维护成本,本申请还提供了一种驱动桥。
