Wheel hub ring flange before oil -electric hybrid vehicle

The utility model relates to a wheel hub ring flange especially relates to a wheel hub ring flange before oil -electric hybrid vehicle. It mainly is that to solve the ring flange intensity that wheelhub bearing unit that prior art exists adopted less, and it is comparatively serious to wear and tear, and the greasy property is relatively poor to can't play the effect of buffering, transmission efficiency is lower, the higher technical problem who waits of energy consumption. The utility model discloses a flange plate (1), flange plate (1) go up cross -under and have bolt (2), flange plate's hole one end is equipped with cavity (3), flange plate's root is equipped with step (4), step one end is equipped with the section for enhancement alloy -layer (5) of L type, flange plate's root is equipped with the section and cuts alloy -layer (6) for the anti -shear of crescent. 本实用新型涉及种轮毂法兰盘，尤其是涉及种油电混合汽车前轮毂法兰盘。其主要是解决现有技术所存在的轮毂轴承单元采用的法兰盘强度较小，磨损较为严重，润滑性能较差，并且无法起到缓冲的作用，传动效率较低，能耗较高等的技术问题。本实用新型包括法兰盘本体（1），所述的法兰盘本体（1）上穿接有螺栓（2
