Dual clutch Transmission

  1. 1. KALYANI GOVT. ENGG. COLLEGE Dual clutch transmission PRESENTED BY: BISAL KARMAKAR [Roll No.10200715059] UNDER THE SUPERVISION : DIPAK SANYAL M.TECH(I.I.T KHARAGPUR)
  2. 2. Content  What’s clutch  Working of clutch  Why we need new clutch transmission system  Dual clutch Transmission  Advantage & Disadvantage of DCT  Conclusion
  3. 3. CLUTCH A clutch is a mechanical device that engage and disengage the power transmission from driver to driven shaft Allows smooth engagement of engine to transmission
  4. 4. CLUTCH PARTS 4 • Flywheel • Clutch plate • Pressure plate
  5. 5. Working of clutch  When a gear shifting happens…
  6. 6. Working of clutch  First, the clutch is opened.
  7. 7. Working of clutch  Second, driver shifts the gear with the lever.
  8. 8. Working of clutch  Finally, the clutch is closed.
  9. 9. Disadvantage  Waste of fuel  Power-lost during the gear shifting  Discomfort
  10. 10. Overview of DCT  In DCT system two clutches are use  First clutch is engage with odd gears  second clutch is engage with even gears  The gear are controlled hydraulically by a electronic control unit (ECU) which sense the gears position and shifting
  11. 11. Working of DCT
  12. 12. • Power is always transferred to the wheels
  13. 13. Advantages of DCT  No power interruption at gear shifting  Very smooth gear-shift operations  Less fuel consumption  Better drive and Better comfort  Drive faster and faster
  14. 14. Disadvantages of DCT  Expensive to manufacture  Heavier than a conventional manual transmission  Expensive transmission fluids/lubricants with additives
  15. 15. Who are using DCT ?  VOLKSWAGEN  BMW  PORSCHE
  16. 16. CONCLUSION  Better fuel economy up to 15% improvement than conventional transmission  DCT system best for Drive faster as well as comfort and performance.
