Abstract: The steering system components are all important security components, and the design should comprehensively consider the relevant data based on the overall vehicle layout to ensure the safety of the vehicle during driving. This article takes a certain commercial vehicle model as an example to introduce the key hard point verification of the steering system and the matching and selection scheme of the hydraulic power steering system. Through the verification of the steering suspension system, the hard point layout position of the steering system is selected and verified. The key installation dimensions are verified through the overall vehicle layout structure, and the relevant parameters of the hydraulic power steering system are further calculated.The study has a strong guiding significance to the later similar vehicle design.

Key words: Steering system; Matched design; Hydraulic power steering system
