  2. K111 CVT

  3. K111 CVT (Continuously Variable Transmission) • Overall • A metal belt type continuously variable transmission with electronic hydraulic control *1: Planetary Gear Ratio Included *2: Reduction Gear Ratio Included

  4. General AT 1st 2nd 3rd 4th Engine Speed CVT (Shaded Region) Vehicle Speed Speed Ratio K111 CVT • Features of CVT • CVT perform speed ratio control using a pair of pulleys Secondary Pulley Pulley Width = Large Pulley Width = Small Metal Belt Primary Pulley INPUT OUTPUT Pulley Width = Small Pulley Width = Large Low Speed Ratio High Speed Ratio Operation of CVT

  5. : CVT : General AT K111 CVT • Features of CVT • Driving near optimal fuel consumption is allowed Optimal Fuel Consumption Enlarged Fuel Cut Area Specific Fuel Consumption Map Speed Ratio Control Area for CVT 1st 2nd 3rd 4th Engine Torque Engine Speed ON Fuel Cut OFF Engine Speed Vehicle Speed Enlargement of fuel cut area when deceleration Area used when driving

  6. : CVT : General AT K111 CVT • Features of CVT • Engine speed in a high output range can be maintained Maximum Engine Output Point Engine Speed Time Engine Speed During Full Throttle Acceleration

  7. : CVT : General AT Effective Driving Force Area in CVT K111 CVT • Features of CVT • Smooth driving force characteristics High Driving Force High Vehicle Speed Chart of Driving Force Characteristics

  8. K111 CVT • Components Forward and Reverse Drive Shift Mechanism Torque Converter with Lock-up Clutch Primary Pulley Continuously Variable Transmission and Metal Belt Metal Belt Oil Pump Secondary Pulley Reduction Gear Parking Lock Mechanism Differential Gear

  9. K111 CVT • Components 3 Speed Sensors CVT Fluid Warmer Oil Pressure Sensor Overflow Plug Valve Body Unit (Hydraulic Control Unit)

  10. Reference (K111 CVT) • Components (K210 CVT) Secondary Pulley Forward and Reverse Drive Shift Mechanism Torque Converter with Lock-up Clutch Metal Belt Primary Pulley CVT Fluid Warmer K210 CVT

  11. K111 CVT • Torque Converter with Lock-up Clutch • Damper structure allowing lock-up from low speed range Turbine Runner Lock-up Clutch Pump Impeller Stator Damper Structure One-way Clutch

  12. K111 CVT • Oil Pump • The oil pump is combined with the torque converter, lubricates the parts and supplies operating pressure to the hydraulic control Oil Pump

  13. K111 CVT • Gear Train • Consists of a planetary gear, continuously variable transmission, reduction gear and differential gear Reverse Brake Input Shaft Primary Pulley Metal Belt Forward Clutch Secondary Pulley Planetary Gear Unit Reduction Gear Continuously Variable Transmission Final Gear

  14. K111 CVT • Gear Train • Operation (D Position) D position (Lowest Ratio) D position (Highest Ratio) Pulley Width = Large Pulley Width = Small OFF OFF ON ON Pulley Width = Small Pulley Width = Large

  15. K111 CVT • Gear Train • Operation (N and R Position) N position R position Pulley Width = Large Pulley Width = Large OFF ON OFF OFF Pulley Width = Small Pulley Width = Small
