Heavy Duty Truck Steering System Design And Steering Features Matching Research

With the fast development of domestic and international economy,infrastructure and logistics industries have developed rapidly and the truck market has also developed rapidly accordingly.In recent years,heavy-duty trucks have continued to develop in the direction of big horsepower and heavy load under the dual demand of the market and users.Heavy-duty trucks have advantages in terms of transportation efficiency and economy,and have gradually become the first choice for road transportation.Therefore,the development and production of heavy trucks is very important.The car steering system can ensure the normal use and driving safety and has a direct impact on vehicle handling,driving comfort and so on.Therefore,matching and applying heavy-duty steering system has important practical significance for ensuring vehicle driving safety and improving vehicle handling and comfort.This paper takes heavy-duty truck steering system as research object.Firstly,it introduces the type and composition of the steering system and the selection and layout requirements of the relevant components in the matching application process,focuses on the design check of steering gear,linkage and steering pump..Then,through the simulation of the vehicle kinematics,the matching rationality of the steering system is verified from the system perspective.According to the vehicle steering system evaluation and test method,the matching rationality of the steering system is verified from the vehicle level.Finally,analyze vibration and noise problems in the steering system in matching application process,compare and analyze noise reduction effects of different noise reduction pipes by changing the pipes damping.A set of solutions to solve the problem of steering system noise is obtained.The research of this subject provides a more scientific method for the matching and applying of heavy-duty truck steering system.By design verification,simulation analysis and vehicle testing,the steering system is effectively matched and verified.The analysis and solution for noise of the steering system provides the basis for improving the comfort of the steering system.This paper has gained experience and practical guiding significance for the development of heavy-duty truck steering systems.
