The invention relates to a two-gear rotatable hub motor four-wheel-drive trolley which is characterized by mainly comprising a rack-and-pinion steering gear, a power-assisted steering motor, a steering gear set, a reversing transmission shaft, a two-gear hub motor and a signal processor. Wide-angle reversing and transverse movement can be achieved while the normal trolley reversing angle is achieved, two forward gears, one parking gear and one neutral gear can be achieved through the hub motor used in the invention, and meanwhile, the trolley has the advantages of being compact in structure, simple in gear shifting mode, high in transmission efficiency, high in steering freedom degree and the like. A new scheme reference is provided for a reversing mode and a transmission structure of an existing electric four-wheel drive vehicle, and good use value and application prospects are achieved.
本发明涉及一种两档可旋转轮毂电机四驱小车,其特征主要由齿轮齿条式转向器、转向助力电机、转向齿轮组、换向传动轴、两档轮毂电机、信号处理器组成。本发明在实现正常小车换向角度同时可实现大角度换向以及横行,发明所使用的轮毂电机可实现2个前进挡,1个驻车档和1个空挡,同时本发明具有结构紧凑、换挡方式简单,传动效率高、转向自由度高等特点,对现有的电动四驱车的换向方式和传动结构提供了一种新的方案参考,具有较好的使用价值和应用前景。
