How to design the steering system of commercial vehicles, and how to determine the front, back, left and right positions of steering gear.

Generally, the steering system first determines the installation position and fixed point of the steering wheel according to the engineering position of the human body, and can refer to the reference of the benchmark vehicle model and determine the steering load according to the performance parameters of the whole vehicle, with mechanical or hydraulic power assistance and full hydraulic pressure. General steering gear manufacturers have ready-made products to choose from, unless special circumstances require development, and the cycle and cost are relatively large. Connect according to the position of the front axle and check whether the use of sports space meets the requirements. Hydraulic pressure also needs to arrange the connection state of pipes and so on.
