The invention discloses a new energy commercial vehicle steering system which comprises a steering wheel, a column tube with an intermediate shaft assembly, a steering gear, a steering plumbing arm, a steering straight pull rod, a left steering knuckle, a right steering knuckle and a transverse pull rod arranged between the left steering knuckle and the right steering knuckle and further comprises a pair of connecting pull rods. The steering straight pull rod is connected with the steering knuckle on one side in a hinged manner, the knuckle on each side is hinged to the butt joint end of the transverse pull rod through the corresponding connecting pull rod, and an electric power assisting structure is arranged on the steering gear. The electric recirculating ball type steering system adopting the disconnected steering trapezoidal structure can provide larger assisting power compared with an electric gear rack type steering gear, can provide reliable steering assisting power for a vehicle with the front axle load of 1.6-3 tons, and does not need to adopt a high-price electric hydraulic pump, so that the cost of parts of the system is low, high energy consumption required by the electric hydraulic pump is avoided, due to the absence of steering fluid, the problems of oil leakage and oil seepage do not exist; and stability and reliability are realized.
本发明公开了一种新能源商用车转向系统,包括方向盘、柱管带中间轴总成、转向器、转向垂臂、转向直拉杆、左右转向节以及设在左右转向节之间的横拉杆,还包括一对连接拉杆,所述转向直拉杆与一侧的转向节铰接相连,每侧的转向节与横拉杆对接端之间通过对应的连接拉杆铰接相连,转向器上设有电动助力结构。采用断开式转向梯形结构的电动循环球式转向系统,其能提供的助力相对电动齿轮齿条式转向器大,可以给前轴载荷在1.6吨‑3吨车辆提供可靠转向助力,不需要采用高价的电动液压泵,从而系统零件成本低,没电动液压泵需要的高能耗,因没有转向液,不存在漏油渗油问题;并且稳定可靠。
