The invention belongs to the field of electric automobiles, and discloses a hub reduction driving system adopting idle wheel transmission, which comprises a disc brake (1), a driving motor (2), a hub bearing (4), an idle wheel speed reducer (5), a rim (6) and a hub (7), the idle wheel speed reducer (5) is mounted between the driving motor (2) and the hub (7), power is transmitted from the driving motor (2) to the idle wheel speed reducer (5) and is output to the hub (7) after speed reduction and torque increase, and the hub bearing (4) is driven by the hub bearing (4). The wheels are driven to rotate. The disc brake solves the problem that brake calipers of a traditional disc brake are too large in size and occupy the internal space of a rim. According to the idle gear speed reducer, the two idle gears are installed between the small gear and the gear ring, the problem that the small gear is too close to the inner gear, and consequently a motor and the inner gear structure are prone to interference is solved, and meanwhile the bearing capacity is improved conveniently through a double-idle-gear transmission structure.

    本发明属于电动汽车领域,公开了一种采用惰轮传动的轮边减速驱动系统,盘式制动器(1)、驱动电机(2)、轮毂轴承(4)、惰轮减速器(5)、轮辋(6)和轮毂(7),惰轮减速器(5)安装于驱动电机(2)与轮毂(7)之间,动力从驱动电机(2)传递到惰轮减速器(5),经减速增扭后输出至轮毂(7)上,驱动车轮转动。本发明解决了传统的盘式制动器的制动卡钳体积过大占用轮辋内部空间的问题。惰轮减速器将两个惰轮安装在小齿轮和齿圈之间,解决小齿轮过于靠近内齿轮,容易造成电机与内齿轮结构干涉的问题,同时也便于通过双惰轮传动结构,提高承载能力。
