What is the main function of a car differential?

The main function of a car differential is to ensure that both driving wheels perform pure rolling motion. Below is an introduction to the differential: 1. Introduction: The car differential enables the left and right (or front and rear) driving wheels to rotate at different speeds. It mainly consists of left and right axle gears, two planetary gears, and a gear carrier. 2. Function: Its purpose is to allow the left and right wheels to roll at different speeds when the car is turning or driving on uneven road surfaces, ensuring that both driving wheels perform pure rolling motion. 3. Objective: The differential is designed to adjust the speed difference between the left and right wheels. In four-wheel drive systems, to drive all four wheels, they must be connected. If all four wheels were mechanically connected, the car would not be able to rotate at the same speed when driving on curves. To allow the car to maintain a relatively consistent rotational speed during curve driving, a center differential is added to adjust the speed difference between the front and rear wheels.
I've been driving for years, and I truly understand the importance of car differentials. Every time you take a turn, the inner and outer wheels travel different path lengths—the outer wheel needs to rotate faster, otherwise the car may skid or wear out the tires. The differential perfectly solves this issue. It's like a tiny mechanical hero, automatically distributing power during turns, allowing the wheels to rotate at different speeds freely. Ever tried driving without one? The car would creak and even lose control on slippery roads—how dangerous! In daily driving, this component protects the suspension system and extends tire life. I recommend regularly checking the differential fluid to prevent jamming. When taking sharp turns at high speeds, it makes driving smoother and more seamless—absolutely a must-have for modern cars.
