Differential action during cornering State whether the differential allows the left and right drive wheels to rotate at different speeds while turning.

Difficulty: Easy

Correct Answer: True

Explanation:


Introduction / Context:
When a vehicle turns, the outer wheel travels a longer path than the inner wheel. The differential accommodates this by allowing different wheel speeds while transmitting torque.



Given Data / Assumptions:

  • Open differential with bevel gears (or limited-slip variants) in a typical axle or transaxle.
  • Tire radii approximately equal; no wheel hop.



Concept / Approach:
An open differential splits input torque and permits differential motion via spider and side gears. The average speed of the two axle shafts equals the input speed ratio, but each side can rotate faster or slower than the other as needed in a turn.



Step-by-Step Solution:
Entering a corner: outer wheel path length increases.Differential gears allow outer wheel to rotate faster, inner slower.Traction remains adequate if road friction supports the torque.



Verification / Alternative check:
Jack up one wheel of a vehicle in neutral: rotating one wheel causes the other to turn in the opposite direction, demonstrating relative motion between sides.



Why Other Options Are Wrong:
The action is independent of ABS and drivetrain layout; both FWD and RWD (and AWD with differentials) need speed differentiation; it operates at all speeds, not only low speeds.



Common Pitfalls:
Assuming a differential “sends power to both wheels equally” regardless of traction—an open differential biases torque to the path of least resistance without additional devices (LSD, lockers, brake-based torque vectoring).



Final Answer:
True
