Automatic Transmission Final Drive

Introduction

Automatic Transmission Final Drive is an essential part of the transmission system that transmits torque to the wheels. It is responsible for the final reduction of the transmission’s output speed to the required wheel speed. A final drive is typically used in vehicles that have an automatic transmission, and it is located at the rear axle.

Working Principle

The Automatic Transmission Final Drive works by using a series of gears to reduce the speed of the transmission output shaft. These gears transmit the torque to the wheels, which causes them to rotate at a reduced speed. The final drive ratio is determined by the number of teeth on the ring gear divided by the number of teeth on the pinion gear.

Types of Final Drives

  • Hypoid final drive
  • Worm gear final drive
  • Planetary gear final drive
  • Spur gear final drive
  • Bevel gear final drive
  • Spiral bevel gear final drive
  • Helical gear final drive
  • Double reduction final drive
  • Single reduction final drive
  • Triple reduction final drive
