Who Invented the Differential Lock?

[LaColin]

Louis Renault, the founder of the French company Renault, invented the differential over a hundred years ago, an indispensable device in automobiles. Below is an introduction to the differential: Main Introduction: Typically, it is installed together with the main reducer to form an assembly. The differential consists of the differential case, left and right axle shafts, planetary gears, and cross shaft. The driven gear of the main reducer is mounted on the differential case, integrating with the differential as a whole. This assembly is then installed in the main reducer housing, forming what we commonly know as the main reducer assembly, colloquially referred to as the rear axle or final drive. Function of the Differential: Primarily, it transmits power to both axle shafts. When the vehicle turns, it allows the two axle shafts to rotate at different speeds, enabling the wheels to move at varying distances in a pure rolling manner as much as possible. This reduces the resistance during turns and minimizes friction between the tires and the ground, thereby extending tire life. It can be said that the differential is an essential component in trucks.
