The Fundamentals of Modern Vehicle Transmissions
EDU Trainings s.r.o.
Popis kurzu
Today’s vehicles apply the primary function of a transmission: to couple the engine to the driveline and provide torque ratios between the two. How is this achieved? This on-demand course will familiarize you with the operational theories and functional principles of modern vehicle transmission systems designed to achieve the most efficient engine operation.
Participants will learn about current designs, the components and sub-systems used, their functional modes, how they operate, and interrelationships. An explanation of ratios and how they function within the driveline by using a manual transmission display is provided, followed by a description of the concepts of automatic control and hydro-mechanic decision theory and implementation using automatic transmission design.
Various transmission models and components to supplement these theoretical concepts with practical, „hands-on“ experience are demonstrated, and a discussion of mechatronics, toroidal transmission functions, and the future of the automatic transmission is included.
Finally, the course provides in-depth coverage of Continuously Variable Transmission (CVT) systems. These systems represent a fundamental shift in the way power is transmitted from the primary source to the remainder of the driveline.
Based on the popular classroom seminar, the course is divided into nine modules, accompanied by a workbook.
Objectives
By participating in this On Demand course, you will be able to:
Explain the development, operational aspects, and design principles of passenger vehicle and light truck transmission systems, their major components, and their sub-systems
Describe the operational parameters and interrelationships of each of the sub-systems
Apply basic design synthesis and analysis techniques for each of the major components and sub-systems
Compare and contrast “stepless” to “stepped” transmission technology
Identify and describe the function and operation of all major components and sub-systems
Recognize the limitations, technological trends, and potential new products under consideration
Summarize the direction of new passenger car transmission designs and systems
