Analysis of Part-Time Four-Wheel Drive Vehicle 820743

This paper reviews the operation of the part-time four-wheel drive vehicle on a high friction paved road. A summary of our investigations follows:
  1. 1)
    The difference in tire radius between the front and rear wheels has a significant influence on traction.
  2. 2)
    When braking, the torque which occurs in the drive line is much larger with four-wheel drive.
  3. 3)
    The driving resistance of four-wheel drive is different from that of two-wheel drive; it is smaller when driving force is in operation.
