The commercial vehicle power-assisted steering device with the large torque output comprises a steering gear body and a speed reducer, the steering gear body comprises a steering gear shell, a steering rocker arm shaft, a lead screw and a circulating ball assembly, the lead screw is installed in the steering gear shell, the circulating ball assembly acts on the lead screw, and the steering rocker arm shaft is connected with the circulating ball assembly. According to the commercial vehicle power-assisted steering device with the large torque output, the input large torque is reduced through the planetary gear with the large transmission ratio, steering assistance is directly provided through the motor, a power steering oil pump, a hose, hydraulic oil, a conveying belt and a belt pulley installed on an engine which are necessary for a hydraulic power steering system are omitted, energy is saved, and the power-assisted steering device is convenient to use. And the environment is protected. The steering device has great design flexibility, is compact in structure and small in size, is more suitable for commercial large-torque vehicles, fills the blank of an electric power steering gear, is green and efficient, and can improve the operation comfort of a driver in the driving process.

    本发明涉及一种大扭矩输出的商用车助力转向装置,包括转向器主体和减速器,转向器主体包括转向器壳体、转向摇臂轴、丝杆和循环球组件,丝杆安装在转向器壳体内,循环球组件作用在丝杆上,转向摇臂轴与循环球组件连接。本发明的大扭矩输出的商用车助力转向装置,通过较大传动比的行星齿轮降低输入的大扭矩,由电机直接提供转向助力,省去了液压动力转向系统所必须的动力转向油泵、软管、液压油、传送带和装于发动机上的皮带轮,既节省能量,又保护了环境。本发明的转向装置有着极大的设计灵活性且结构紧凑、体积小,更适用于商用大扭矩车辆,填补了电动助力转向器在这一块的空白,绿色高效的同时还也能提升驾驶员驾驶途中操作的舒适度。
