Questions and Answers

What is the formula to calculate wheel torque at full load based on engine speed and gear ratio?

  • (Te + rw) / ZF6HP26 gear ratio
  • Te x (rw + ZF6HP26 gear ratio)
  • Te / (rw x ZF6HP26 gear ratio)
  • Te x rw x (ZF6HP26 gear ratio) (correct)

    • How does the wheel radius affect the calculation of wheel torque in a vehicle?

  • Wheel radius affects engine torque, not wheel torque
  • Increasing wheel radius decreases wheel torque
  • Increasing wheel radius increases wheel torque (correct)
  • Wheel radius has no effect on wheel torque

    • What is the main purpose of knowing the final drive gear ratio in vehicle dynamics calculations?

  • To calculate the engine speed at full load
  • To calculate the wheel speed at full load (correct)
  • To understand the relationship between engine torque and gear ratios
  • To determine the tire width of a vehicle
