CouplingIs used to connect two shafts in different mechanisms(Drive shaft and driven shaft)A mechanical part that rotates together to transmit torque.
Universal joints can also be called couplings. Couplings are classified into transmission parts, which are divided into rigid couplings, elastic couplings, eccentric couplings, and universal couplings. They are all couplings. Different, the selection and use conditions are also different
Universal joint,It is a part that realizes variable-angle power transmission. It is used to change the position of the transmission axis direction. It is the universal transmission device of the automobile drive system."joint"part.The combination of universal joint and drive shaft is called universal joint transmission.On a front-engine rear-wheel drive vehicle, the universal joint transmission is installed between the output shaft of the transmission and the input shaft of the transaxle final drive;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, which are responsible for driving and steering.
