There are many varieties of our common universal joints, whether it is Hooke, ball cage, bump, or three-pin type, they can be briefly divided into constant velocity universal joints and non-constant velocity universal joints. The precision universal joint is one of them.
The combination of universal joint and driveshaft is called universal joint transmission. On the front-engine rear-wheel drive vehicle, the universal joint transmission is installed between the transmission output shaft and the input shaft of the drive axle final reducer; while the front-engine front-wheel-drive vehicle omits the transmission shaft, and the universal joint is installed Between the front axle half shaft and the wheels that are responsible for both driving and steering.
The earliest universal joints did not come from vehicles, but the essence of European machinery, clocks. From 1352 to 1354, the universal joint drive shaft in the cathedral clock mechanism can be said to be the birth of the universal joint. The universal joint has a history of hundreds of years since it was invented and used, and the universal joint manufacturer has also existed for a long time, so the universal joint at this stage will continue to improve.
