Question: What is the primary function of a limited-slip differential in heavy equipment?
Answer options: ✅ To allow some torque transfer to the wheel with traction when one wheel slips
- To completely lock the differential for maximum traction at all times
- To reduce axle wind-up during turns
- To improve fuel economy by disengaging an axle
Correct answer: To allow some torque transfer to the wheel with traction when one wheel slips
Explanation: Unlike an open differential, a limited-slip differential can transfer a certain amount of torque to the wheel with better traction when the other wheel starts to slip. This improves traction in varying terrain conditions without completely sacrificing the differential action needed for turning.
