GJP automotive universal joint bearing is a mechanism that realizes variable-angle power transmission. It is used to change the position of the transmission axis. It is the “joint” part of the universal transmission of the automobile drive system. The combination of a universal joint and a transmission shaft is called a universal joint transmission. In front-engine rear-wheel-drive vehicles, a universal joint transmission is installed between the transmission output shaft and the drive axle main reducer input shaft; while front-engine front-wheel-drive vehicles omit the drive shaft, the universal joint is installed Between the front axle axle and the wheels, which both drive and steer.

It can be divided into unequal velocity joints, quasi-constant velocity joints, constant velocity joints.

The structure and function of the universal joint is similar to the joints on the human limbs, which allows the included angle between the connected parts to change within a certain range. In order to meet the angle change caused by power transmission, adaptive steering, and up-and-down jumps that occur when the car is running, the drive axles of front-drive cars are usually connected with universal joints between the axle and the axle. However, due to the limitation of the axial size, the required deflection angle is relatively large. A single universal joint cannot make the instantaneous angular velocity of the output shaft and the shaft into the shaft equal, which easily causes vibration, exacerbates the damage of components, and generates a lot of noise. Therefore, various constant velocity universal joints are widely used. In front-drive cars, two constant velocity joints are used for each semi-axle, the joints near the transaxle are the inner joints of the semi-axle, and the ones near the axle are the outer joints of the semi-axle. In rear-drive cars, the engine, clutch, and transmission are mounted on the frame as a whole, and the drive axle is connected to the frame through an elastic suspension. There is a distance between the two, which needs to be connected. The unevenness of the road surface during the running of the car, the load change, or the position difference between the two assembly installations will cause the angle and distance between the transmission output shaft and the drive axle main reducer input shaft to change. The universal joint transmission uses double universal joints, that is, there is a universal joint at each end of the transmission shaft, and its role is to make the included angle of 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.

The automotive universal joint bearing refers to the mechanical structure that uses the ball connection to realize the power transmission of different shafts, and is a very important part of the automotive bearing. The combination of the universal joint and the drive shaft is called a universal joint transmission.

Classification of automotive universal joint bearing: constant velocity universal thrust ball bearing joints, constant velocity universal joints, ball cage universal joints, three-pin shaft universal bearing joints, double factory-connected universal joints, etc.

working principle

When the driving fork is linear bearing in the vertical position, and the plane of the cross shaft is perpendicular to the driving shaft. At this time, the line speed of the connection point between the driving fork and the cross shaft and the connection point of the driven fork and the cross shaft on the plane of the special cross bearing shaft are equal. The speed projection of the driven fork to the plane of the cross axis, because when the non-independent suspension thrust roller bearing frame is used, the first condition is difficult to meet, and the relative positions of the transmission and the main reducer are constantly changing, and the unequal speed can only be achieved as much as possible. Small.

The unequal velocity of the 10-axis universal joint means that the angular velocity of the driven shaft is uneven in a circle, so the driven shaft is fast and slow. The unequal speed of the transmission when the angle is included. The angle between the two shaft angular contact ball bearings of the first universal joint is equal to the angle between the two shafts of the second universal joint.

The double cross shaft universal joint realizes the condition of constant speed transmission between the output shaft of the transmission between the two shafts and the input shaft of the drive axle. Velocity projection of the cross plane. The bearing driven fork of the first universal joint is in the same plane as the driving fork of the second universal joint. The rotational speed of the main and driven shafts is related to the bearing system. The greater the angle between the two shafts, the greater the rotational speed, and the worse the unequal speed of the drive shaft.
