The technology of continuously variable transmissions spans belts (both 'push' and 'pull'), 'disc-on-wheel', and toroidal. All common CVT technologies rely on friction, and typically require special fluids for optimum operation. CVT technology is one of a core of technologies commonly employed when smooth transition from one speed ratio to another is required and when powertrain system optimization relies on precise ratio control. This webinar will highlight the various mainstream CVT technologies as they apply to automotive applications – fundamental operational principals, the reliance on friction as the primary means to transmit power, and the specific characteristics of the common fluids used in these types of transmissions.

This webinar will provide those with a basic understanding of automotive transmission operation and components the fundamentals of continuously variable transmission technology, its application to the automotive marketplace, and the significance of this technology as it applies to improvements in powertrain efficiency and affectivity. You will also receive insights into the various types of CVT systems, review their relative differences from a 'theory of operation' point of view, and as a function of their core components. Further, Dr. McVea will explore the versatility and operator satisfaction that vehicles equipped with CVT systems can provide as well as some of the limitations to the core technology and limits on practical implementation.

Learning Objectives
By connecting with this webinar you will be able to:

  • Identify, describe, and explain what continuously variable transmission (CVT) technology is, how it works, and what are the various types and underlying functional concepts of this transmission technology
  • Explain the technical, operational, and financial benefits of CVT technology to the OEM, vehicle service personnel and owner/operators
  • Compare and contrast the function of CVT-equipped vehicles versus vehicles with simple manual or automatic transmissions
  • Describe all the various manifestations and configurations of CVT technology when applied to actual and/or conceptual transmission systems of today
  • Compare and contrast system benefits, limitations and practical consideration of adopting CVT technology

Who Should Attend
This webinar will benefit anyone involved in the design, analysis, development, service, customer support or sales of automotive transmission and/or powertrain components and systems. The material covered in this webinar should be considered a core adjunct to your current knowledgebase. The value of this webinar also extends to anyone involved in the vehicle powertrain design and/or application of the technology.

Prerequisites
A basic understanding of automotive transmission technology and a BS in mechanical engineering or a related field is recommended.
