摘要
当前,电动轮技术已经广泛应用于新能源汽车中,提出了一种基于新型摆线包络行星减速器的电动轮毂,该新型电动轮毂以永磁无刷直流电机为驱动,采用承载能力大、体积小、刚度高的新型摆线包络减速器作为主传动装置,实现电机-驱动装置-轮壳的整体设计。应用于该轮毂的高性能减速器的主啮合副由摆线齿轮和摆线二次包络内齿轮组成,输出机构采用双圆盘简支滚子滑槽浮动盘形式;给出了摆线二次包络内齿轮的啮合方程和齿廓方程,论证了该啮合副的一对啮合齿在一定范围内存在二次作用现象。基于该新型摆线包络行星减速器的电动轮毂具有过载能力大、体积小、集成度高、制造成本低等特点,应用于电动轮中可实现单轮驱动或全时四驱的功用。
Nowadays the technology of electric wheel is widely used in new energy vehicles.An electric wheel based on a new type of cycloid envelope planetary reducer is proposed.The PM brushless DC motor is selected as a power source.The cycloid envelope planetary reducer with high load capacity,small volume and high stiffness is the main drive device.The overall design of motor-driving device-wheel housing is realized.The main meshing pair of this high performance cycloid reducer with floating disc type output mechanism is composed of cycloid gear and double-envelope internal gear.The meshing and tooth profile equations of cycloid double-envelope internal gear are respectively derived.The characteristic of secondary action during the engagement process is demonstrated.This developed electric wheel based on the cycloid envelope planetary reducer has the characteristics of large overload capacity,small volume,high integration and low manufacturing cost.It can be applied to electric vehicles and achieve the function of single-wheel drive or all-wheel drive.
