Ugears Differential Voice Lab

The differential is a stylized educational modeling package, an interactive study guide to the mechanism, just for learning the essentials and principles of operation. The differential is designed to ensure that drive wheels sitting on the same axle rotate at different speeds while traveling different distances. This mechanism enables the car to make turns without the wheels slipping, prevents wheel slip, reduces tire wear and makes entering and exiting turns easier for the driver.

After installing the differential, you can unlock it by pushing the lever to position 1 (up) and set both wheels in motion by turning the drive or wheel. The control lever independently controls the smooth locking of the left and right wheels by turning left or right, respectively. In the “down” position of the lever, both wheels are connected together in a rigid linkage and can either rotate together (driven by the drive sprocket or a wheel) or lock simultaneously (by the wheel lever).

The auto differential was invented by French engineer Onesiphore Pecqueur in 1825. In the 1930s, German automotive engineer Ferdinand Porsche made significant improvements to the device.
