topic : The steering system is one of the seven basic, most important systems in an automobile While the engine and system transmit power to the wheel, the steering system is used to change the direction of motion or keep the car moving in a certain trajectory such as: turning left, turning must, go straight… The steering system is a rather complex system, it is divided into many clusters of mechanisms and parts with separate functions that support each other 1.2 Topic goal The goal of the group when implementing the topic is to help students better understand the structure and use of the steering system as well as how to deal with problems with the steering system 1.3 The content of the topic Week 1: Assign topics Week 2: Analyze and get detailed design data Week 3: Planning, detailed design process Week 4: Calculation and preliminary design of the system Weeks 5, 6: Design details according to the outlined process Week 7, 8: Completing 2D design drawings including projections and cross-sections Week 9: Edit 2D design drawings (if necessary) Week 1: Complete the project Closed into a book for the lecturer to sign for approval proceed to protect the project to 1.4 RESEARCH METHODS: Information from available documents and from social networks 1.5 STRUCTURE OF THE PROJECT Consists of Chapters Chapter 1: Introduction to the document Chapter 2: Basic theory Chapter 3: Computational Design Chapter 4: Model/simulation construction Chapter 5: Conclusion and development direction 9|Page Chapter 2: Basic theory 2.1 Common use * Used to change the torque from the engine to the driving wheels when the car is moving in a certain direction * Used to change the torque between perpendicular axes when the car is moving in a specified direction * Used to change the direction of motion or keep the car moving steadily in a specified direction 2.2 The function of Steering system In the process of automobile movement on the road, the steering system has a great influence on the safety of movement, especially at high speed, so it must ensure the following requirements 1) The function of a steering system is to convert the rotary movement of the steering wheel in driver’s hand into the angular turn of the front wheels on road 2) Additionally, the steering system should provide a mechanical advantage over frontwheel steering knuckles, offering the driver and easy turning of front wheels with minimum effort in any desired direction 3) Steering system provides the directional change in the movement of an Automobile and maintains in a position as per the driver’s decision without much strain on him 4) This system converts the rotary movement of the steering wheel into the angular movement of the front wheels It multiplies the driver’s effort by mechanical advantage, enabling him to turn the wheels easily 5) In addition to the above requirements there are also possible requirements tools for the steering system as follows: With power assisted system steering, when the support system has a fixed failure, car can still be controlled Convenient in use and maintenance Thanks to the regulations on the safety of movement of car, the steering system is improved 10 | P a g e Click Insert Components Click Browse 124 | P a g e and Click Vo Thanh Rang.SLDPRT after Click Open Click Browse 125 | P a g e and Click Truc lai.SLDPRT after Click Open

the engine's power to create hydraulic oil pressure to support the rotation of the guide wheels to change the direction of the car's movement 135 | P a g e Chapter Conclusion and development direction Through the process of researching, researching and implementing this project I also understood the basics of the steering system Especially the content on the basis of calculation and design of the car's steering system From there learn more experience and knowledge about the steering system Due to the limited knowledge, our topic still has many limitations in terms of content and practical experience, so in the process of implementation and presentation, it is inevitable that there will be shortcomings in terms of content I hope you will give us more feedback so that we can improve more and more We hope that after completing this subject project, we will have a better understanding of the knowledge so that we can design, calculate and offer a complete driving system on the automobile market in Vietnam and Vietnam the whole world 136 | P a g e References BMFT (1981) Tribologie und Verschleiß Guy A (1976) Oberflächenverfahren University Florida—Korrosionsmechanismen Fig 12.24 ZF
