The invention discloses a modular integrated wet-type steering drive axle for an outer swing frame of a wheel excavator. The drive axle comprises an axle housing module serving as a matrix module, anda wheel edge module, a brake module, a swing steering module and a main reduction module which are integrated on the axle housing module; the wheel edge module is connected with the axle housing module through a conical end set screw, a spline pair, a locking nut, a supporting pad and a bearing; the wheel edge module is connected with the brake module through a spline pair; the brake module is connected with the axle housing module through a bolt group; the swing steering module is connected with the axle housing module through a bolt group and a bearing; and the main reduction module is connected with the axle housing module through a spline pair and a bolt group. According to the steering drive axle, an existing mature axle differential principle is adopted, planetary gear transmissionand common straight-tooth gear transmission are fused, a normally-open multi-piece type wet-type brake technology is adopted, a reciprocating type hydraulic steering oil cylinder is provided, the steering requirement of the steering drive axle is met by optimizing a steering system of the steering drive axle, and the steering drive function is achieved.

    本发明公开一种模块化集成式轮式挖掘机外摆架湿式转向驱动桥。包括作为基体模块的桥壳体模块,及集成于桥壳体模块上的轮边模块、制动器模块、摆动转向模块和主减模块;轮边模块通过锥端紧定螺钉、花键副、锁紧螺母、支撑垫及轴承与桥壳体模块连接;轮边模块与制动器模块之间通过花键副连接;制动器模块通过螺栓组与桥壳体模块连接;摆动转向模块通过螺栓组、轴承与桥壳体模块连接;主减模块通过花键副及螺栓组与桥壳体模块连接。本转向驱动桥采用现有的,成熟的车桥差速原理,行星齿轮传动和普通直齿齿轮传动相融合,加上常开多片式湿式制动器技术,提供往复式液压转向油缸,通过优化其转向系统,实现其转向要求,实现转向驱动功能。
