The invention discloses a large-angle drive-by-wire independent steering mechanism based on a hub motor. The large-angle drive-by-wire independent steering mechanism comprises a first power module, a second power module and a steering execution module. The first power module is composed of a first motor, a worm gear lead screw speed reducer and a lead screw. The second power module is composed of a second motor, a ball screw, a ball screw sliding block, a slewing bearing and a connecting piece. The steering execution module comprises a steering knuckle, a brake assembly, a hub motor, a tire hub and a suspension assembly. The turning angle of-45 degrees to 45 degrees of the wheels can be achieved through the first power module, if large-angle turning or vehicle transverse running requirements exist, the wheels can be turned to 90 degrees through the second power module, and power distribution is optimized. Through cooperation of the two power modules, large-angle independent steering of the drive-by-wire automobile can be achieved, the functions of straight movement, steering, oblique movement, transverse movement, in-situ turning and the like of the electric automobile can be achieved, feasible scheme design is provided for an independent steering structure of the drive-by-wire automobile, and good steering performance and application value are achieved.
本发明公开了一种基于轮毂电机的大角度线控独立转向机构,包括第一动力模块、第二动力模块和转向执行模块。第一动力模块由第一电机、蜗轮丝杆减速器和丝杆构成,第二动力模块由第二电机、滚珠丝杠、滚珠丝杠滑块、回转支承和连接件构成;转向执行模块包括转向节、刹车总成、轮毂电机、轮胎轮毂以及悬架总成。本发明可通过第一动力模块使车轮实现‑45°~45°的转角,若有大角度转向或车辆横行需求,可通过第二动力模块将车轮转向至90°,优化了动力分配。本发明通过两动力模块的配合可实现线控汽车大角度独立转向,可实现电动汽车直行、转向、斜行、横行及原地转圈等功能,为线控汽车独立转向结构提供了可行的方案设计,具有良好的转向性能和运用价值。
