The invention relates to a disconnected wheel edge electric drive assembly which is mainly composed of a speed reduction device, a drive motor and an output device assembly. The speed reducer is arranged in a hollow cavity of the driving motor; a rotating shaft of the driving motor is in spline fit with a central hole of the sun gear; the output device and the sun gear output end of the speed reduction device are coaxially installed, and a mechanical transmission and matching interface is arranged at the end of the output device. According to the invention, a single motor is coaxially integrated with a single-row planetary reduction gear of a two-section V-shaped helical gear, the cooling and lubricating integrated design of a driving motor and the reduction gear is adopted, and the design is matched with the same interface of a traditional H-shaped mechanical transmission side transmission box; the wheel-side electric driving power assembly which integrates driving, speed reduction and supporting and is efficient, high in power density, small in size, light in weight and highly integrated is formed.
本发明涉及一种断开式轮边电驱总成,主要由减速装置、驱动电机、输出装置总成组成;所述减速装置置于驱动电机的中空空腔内,驱动电机的转轴与太阳轮中心孔花键配合;输出装置与减速装置的太阳轮输出端同轴安装,输出装置端部设有机械传动同匹配接口。本发明通过采用单电机同轴集成两段式V字形斜齿轮的单排行星减速装置、驱动电机与减速装置冷却润滑一体化设计,与传统H型机械传动侧传动箱同接口匹配设计,形成集驱动、减速、支撑为一体的高效的、高功率密度的、小体积、轻量化的、高度集成的轮边电驱动动力总成。
