Description

Technical Field

[0002] A center differential is a device that allows the two half-axles to rotate at different speeds. It's primarily used in multi-axle vehicles to eliminate speed differences between the drive axles and prevent drive wheel slip. Center differentials offer a variety of locking methods, including high-friction self-locking and viscous coupling. Their primary purpose is to reduce friction between the tires and the road, improving vehicle efficiency and stability.

[0003] Common remote-controlled model cars currently on the market often have their center differential and motor mounted off to one side. This motor placement (either on the left or right side of the chassis) consistently shifts the center of gravity to the side where the car weighs the most, affecting handling. Furthermore, the open structure of existing center differentials can easily allow small gravel to enter during driving, damaging the gears and shortening their service life. Furthermore, existing center differentials are difficult to install and debug, requiring repeated adjustment of gear clearances after disassembly and maintenance, which is a significant hassle.
