Contents

In this lecture, the use of machine elements in vehicle transmissions, their function with regard to power transfer as well as the interaction between mechanical design properties and subjective perception of driving and usage comfort by the driver are the subject of discussion. The thematic focus is on following topics:

  • Powertrain Architectures – Conventional, Hybrid and Electric Drive Systems
  • Vehicle Transmission – System properties
  • Torsional Dampening Systems
  • Components and Power Flow in Synchronized Layshaft Transmissions
  • Dry Launch Clutch and Apply System
  • Dual Clutch Systems
  • Spur Gear Transmissions
  • Automotive Shift Systems
  • Aspects of Comfort of Manual Transmissions
  • Sensors and Actuators in Vehicle Transmissions
  • Torque Converter
  • Planetary Gears
  • Power Transfer in Automatic Transmissions
  • Differentials and Torque Distributing Subsystems
  • Heavy Duty Applications
  • Hybrid and electric mobility
  • Friction, Efficiency and Sustainability

The aspects of electric mobility, especially the mechanical challenges of noiseless driving as well as design methods and aspects of comfort are emphasized. The focus is on the mechanical power transfer and the respective components.

The content covers most recent publications from the automotive world and provide up-to-date information about new propulsion technology to the students.
