T-18 is 2 gear transfer case - High gear & Low gear, mechanically shifted. HIGH GEAR RATIO - 1 : 1 LOW GEAR RATIO - 2.46 : 1 All the gears are of sliding mesh type , hence the vehicle needs to be brought to standstill before shifting. BORG-WARNER TRANSFER CASE - Fitted on Scorpio & Bolero. BW is a 2 gear transfer case - High gear & low gear, mechanically or electrically shifted. HIGH GEAR RATIO - 1 : 1 LOW GEAR RATIO - 2.48 : 1 Gear reduction is through planetary gear system & Chain TRANSFER CASE (T-18) FROM GEAR BOX LOW GEAR HIGH GEAR 2WD/4WD COUPLING TO REAR TO FRONT 2WD HIGH 2WD MODE 4WD LOW N 4WD HIGH TRANSFER CASE (T-18) FROM GEAR BOX TO REAR FROM GEAR BOX TO FRONT TO REAR 4WD HIGH MODE 2WD HIGH 4WD LOW MODE 4WD LOW N 4WD LOW N TO FRONT 4WD HIGH 2WD HIGH 4WD HIGH TRANSFER CASE (BORG-WARNER) RING GEAR SUN GEAR FROM GEAR BOX TO REAR PLANET GEAR CHAIN DRIVE 2WD HIGH TO FRONT 4WD HIGH N 2WD MODE 4WD LOW TRANSFER CASE (BORG-WARNER) RING GEAR SUN GEAR FROM GEAR BOX TO REAR PLANET GEAR CHAIN DRIVE 2WD HIGH TO FRONT 4WD HIGH N 4WD HIGH MODE 4WD LOW TRANSFER CASE (BORG-WARNER) RING GEAR SUN GEAR FROM GEAR BOX TO REAR PLANET GEAR CHAIN DRIVE 2WD HIGH TO FRONT 4WD HIGH N 4WD LOW MODE 4WD LOW SAMPLE LEAFLET MARSHAL 2000 TRANSFER CASE : TWO SPEED GEAR REDUCTION SINGLE SHIFT LEVER SPEED RATIO : HIGH - 1 : 1 , LOW 2.46 : 1 PROPELLOR SHAFT PROPOELLOR SHAFT TRANSMITS THE ENGINE TORQUE FROM THE GEAR BOX/TRANSFER CASE TO THE DIFFERENTIAL. PROPELLOR SHAFTS CAN BE EITHER : SINGLE PROPELLOR SHAFT SPLIT PROPELLOR SHAFT SYSTEMS IN AN AUTOMOBILE A. POWER TRAIN SYSTEM • POWER PLANT (POWER GENERATION - ENGINE) • ENGINE • FUEL SYSTEM • INTAKE SYSTEM • EXHAUST SYSTEM • COOLING SYSTEM • DRIVE LINE (POWER TRANSMISSION ) • CLUTCH • GEAR BOX/TRANSMISSION • TRANSFER CASE • DIFFERENTIAL • WHEELS/TYRES B. RUNNING SYSTEM • SUSPENSION • STEERING • BRAKING C. COMFORT SYSTEM • HVAC/AC/HEATER SYSTEM • SEATING/UPHOLSTRY/FACIA/INSTRUMENTS • AUDIO/VIDEO/GPS DIFFERENTIAL DIFFERENTIAL RECEIVES TORQUE FROM THE GEAR BOX, MODIFIES AND TRANSMITS IT TO THE WHEELS, IN A PERPENDICULAR DIRECTION. DIFFERENTIAL ALSO ALLOWS EACH WHEEL TO ROTATE AT DIFFERENT SPEEDS, ESPECIALLY WHEN THE VEHICLE TAKES A TURN COMPONENTS OF DIFFERENTIAL • CROWN WHEEL /PINION (REAR AXLE RATIO) • DIFFERENTIAL GEARS DIFFERENTIAL TORQUE FROM GEAR BOX CROWN/ RING GEAR PINION PLANET PINION RIGHT LEFT AXLE SHAFT SUN GEAR DIFFERENTIAL CAGE DIFFERENTIAL 1. CROWN WHEEL/PINION - Also known as rear axle ratio, is fixed gear reduction at the rear axle. Crown wheel/pinion receives the torque from gear box (through propeller shaft) , multiplies the torque and directs it to both wheels in a perpendicular direction, through the differential. Crown & Pinion pair is known as Hypoid pair. 2. DIFFERENTIAL MECHANISM - Equalise...
