The universal joint is a very important part of the car, the combination of universal joint and driveshaft, known as the universal joint transmission device. There are many types of universal joints, one of which is the 5-153X GU1000 PRECISION 369 universal joint .
In the rear-drive car, the engine, clutch, and transmission are installed on the frame as a whole, and the drive axle is connected to the frame through the elastic suspension. There is a distance between the two, which needs to be connected. Beating in the operation of the road is rough cars, poor load changes or two assemblies installed, can make the gearbox output shaft and the Angle between the drive axle of the main reducer input shaft and the distance change, so in the form of universal joint drive a car powered with a double universal joint, is to have a universal joint on both ends of the transmission shaft, its role is to make the shaft ends of equal Angle, Thus, the instantaneous angular velocity of the output shaft and the input shaft is always equal.
Of course, there are many other types of universal joints, such as the 5-280X PRECISION 334 universal joint . xsjbearing.com
