The invention discloses a triple drive through drive axle with lubricating structures, different cavities are provided with the lubricating structures for independently and separately filling oil at different oil levels to ensure the lubricating requirement of the whole through drive axle, and meanwhile, a high-position bearing and an oil seal in an inter-axle differential cavity are provided with an oil collecting device to realize active lubrication of the high-position bearing; for an inter-axle planet row structure, a lowest oil level limiting structure is arranged, so that lubricating oil is recycled in time when the whole vehicle is in a low static state, the lowest oil level is guaranteed, and meanwhile oil stirring loss under the driving working condition is reduced; and as for a through cavity and a low-position driven gear, an oil blocking isolation device is arranged, redundant oil can be timely shunted to two sides while the gear meets lubrication, lubrication of an inter-axle differential cavity and a high-position bearing is guaranteed, and oil stirring is reduced. The transmission efficiency is high, and the reliability is high.

    本发明公开了一种具备润滑结构的三联驱贯通驱动桥,不同腔体设置不同油位独立分开加油的润滑结构保证整个贯通主减润滑需求,同时桥间差速器腔内的高位轴承和油封设置集油装置实现高位轴承主动润滑;对于桥间行星排结构,设置最低油位限制结构,使得整车低静止状态下,润滑油及时回收,保证最低油位同时降低行驶工况下的搅油损失;对于贯通腔,低位从动齿轮设置挡油隔离装置,齿轮满足润滑同时,多余油能及时分流到两侧,保证桥间差速器腔和高位轴承的润滑,减少搅油。本发明传递效率高,可靠性高。
