The invention discloses a driving steering mechanism which comprises a shell, a bottom plate, a left upper cover plate, a right upper cover plate, a left side cover plate, a right side cover plate, a driving mechanism and a steering mechanism, the driving mechanism comprises a differential assembly, a left first vertical shaft, a right first vertical shaft, a first bevel gear set, a gear set, a left second vertical shaft, a right second vertical shaft, a second bevel gear set and a wheel edge assembly, and a left power output shaft and a right power output shaft are arranged in the wheel edge assembly respectively. The left and right second vertical shafts are respectively connected with the left and right power output shafts through left and right second bevel gear groups; the steering mechanism comprises a left steering shaft, a right steering shaft and a steering oil cylinder used for driving the left steering shaft and the right steering shaft to rotate synchronously, and the left steering shaft and the right steering shaft are rotationally arranged between the bottom of the left gearbox and the bottom of the right gearbox on the two sides of the shell and the bottom plate. The driving steering mechanism is simple and compact in structure and small in size, power transmission and steering do not interfere with each other, large-angle steering can be achieved in a small space, 90-degree steering can be achieved, and accurate synchronization of front tires and rear tires can be guaranteed when the four-wheel-drive vehicle with the front tires and the rear tires different in diameter when the vehicle walks.
本发明公开了一种驱动转向机构,包括壳体、底板、左、右上盖板、左、右侧盖板、驱动机构和转向机构,驱动机构包括差速器总成、左、右第一立轴、第一伞齿组、齿轮组、左、右第二立轴、第二伞齿组及轮边总成,轮边总成内分别设有左、右动力输出轴,左、右第二立轴分别通过左、右第二伞齿组与左、右动力输出轴连接;转向机构包括左、右转向轴及用于驱动左、右转向轴同步转动的转向油缸,所述左、右转向轴均可转动的设置在壳体两侧的左、右齿轮箱底部与底板之间。本发明结构简单紧凑,体积小,动力传递与转向互不干扰,能在小空间内实现大角度转向,可达90度转向,对于前、后轮胎直径不同时的四驱车辆还能保证车辆行走时前后轮胎的精准同步。
