There is a very important part of the car called a universal joint. The combination of the universal joint and drive shaft is called universal joint transmission. In front-engine rear-wheel-drive vehicles, the universal joint transmission is installed between the transmission output shaft and the input shaft of the drive axle final drive;
The front-engine front-wheel-drive vehicle omits the drive shaft, and the universal joint is installed between the front axle half shaft and the wheel that is responsible for driving and steering. Automobile universal joint installation process:
1. The location is on a front-engine rear-wheel-drive vehicle, and the universal joint transmission is installed between the output shaft of the gearbox and the input shaft of the drive axle final reducer;
2. For vehicles with front-engine front-wheel drive, the drive shaft is omitted, and the universal joint is installed between the front axle half shaft and the wheels that are responsible for driving and steering;
3. The part that functions to realize variable-angle power transmission is used to change the direction of the transmission axis to make the angle between the two ends of the transmission shaft equal so that the instantaneous angular velocity of the output shaft and the input shaft are always equal.
