MN MODEL MN168 RC CAR What does the differential do?

The differential distributes torque between the two output shafts (i.e. the left and right half shafts) to ensure that power can be transmitted to the two drive wheels evenly or on demand.
When the remote control car turns, the turning radius of the inner and outer wheels is different, so their rotation speeds also need to be different.
The differential ensures the stability of the remote control car during the turn by balancing the wheel’s trajectory. At the same time, it can also reduce the slip between the tire and the ground, reduce wear, and improve the smoothness and safety of driving.
