FUNDAMENTALS OF STEERING SYSTEMS
“Tim provides a very thorough overview of common steering systems in a practical, easy to understand, hands on manner.” Phil Kling Manager, Product Investigations General Motors of Canada LTD.
Design and development of a modern steering system influences vehicle response, driver controllability, comfort, safety and fuel economy. In this interactive seminar, participants will analyze the steering system, from the steering wheel to the road wheel. The seminar will cover the anatomy and architecture of the lower steering system (wheel end suspension geometry, linkages and steering gear), its e¥ect on vehicle response, and how a force at the contact patch is translated to a torque in the steering wheel. The anatomy and architecture of the upper steering system (steering column and intermediate shaft), including the topic of non-uniformity and the role of the upper steering in the occupant protection system will also be explored. Significant time will be devoted to the generation of power assist, either by way of a conventional hydraulic power steering (HPS) or electrically power assisted steering (EPAS). Topics include system anatomy/architecture as well as the e¥ect of the system on fuel economy. The seminar will finish with a discussion of common steering objective tests and how the kinematics, compliances, friction and power assist a¥ect steering response and torque feedback. Students will have the opportunity to participate in exercises throughout the seminar, culminating in a final project where they will calculate an assist curve for both a HPS and an EPAS system. LEARNING OBJECTIVES By attending this seminar, you will be able to: • Identify common steering and suspension system architectures • Compare and contrast di¥erent types of steering gears • Describe the function of the steering column and intermediate shaft subsystem • Describe the influence of system tuning on steering response and torque feedback • Compare and contrast di¥erent types of power assist systems • Describe the e¥ect of power steering on fuel economy • Calculate important parameters that a¥ect steering response and torque feedback • Describe some of the features of advanced steering systems WHO SHOULD ATTEND Automotive engineers in the vehicle dynamics, chassis, suspension, steering and chassis controls fields who work in product design, development, testing, simulation or research.
