differential

A differential is an essential device in a vehicle’s drivetrain, usually located in the drive axle.

Main Functions

1. Allow different wheel speeds

   • When driving straight, both wheels rotate at the same speed.
     
   • When turning, the outside wheel must travel farther, so it rotates faster.
     
   • The differential lets wheels rotate at different speeds while still receiving power.
     

2. Torque distribution

   • Splits engine torque and delivers it to both wheels.
     

3. Improved handling and stability

   • Without a differential, turning would be difficult and could cause tire wear or drivetrain damage.
     

Common Types

• Open Differential

  • Simple, common type.
    
  • Loses traction if one wheel slips.
    

• Limited Slip Differential (LSD)

  • Restricts excessive wheel speed difference.
    
  • Improves traction on slippery surfaces.
    

• Locking Differential

  • Forces both wheels to rotate at the same speed.
    
  • Useful in off-road conditions.
    

• Active Differential

  • Electronically controlled.
    
  • Adjusts torque distribution dynamically based on driving conditions.
