The universal joint bearing is installed between the front axle axle and the wheel, which is responsible for both driving and steering. In front-engine rear-wheel drive vehicles, the universal joint transmission is installed between the transmission output shaft and the drive axle main reducer input shaft. The combination of universal joint and drive shaft is called universal joint transmission device.
The active fork is bearing in a straight line in a vertical position, and the plane of the cross shaft is perpendicular to the active shaft. At this point, the linear velocity of the connecting point of the active fork and the cross shaft and the connecting point of the driven fork and the cross shaft is equal to that of the special cross bearing shaft plane.
The velocity projection of the driven fork to the cross plane. Because in the use of non-independent thrust roller bearing frame, the first condition is difficult to meet, the relative position of the gearbox does not change constantly, so the unequal speed can only be as small as possible.
The unequal velocity of 10 - axis universal joint. It refers to the uneven angular speed of the driven shaft in a week, then the driven shaft is fast and slow. If the driving shaft rotates at type isometric speed, that is, the unequal speed of transmission of a single cross shaft universal joint when there is an included Angle.
The Angle between the two angular contact ball bearings of the first universal joint is equal to the Angle between the two axes of the second universal joint. The double cross shaft universal joint realizes the constant speed transmission of the output shaft of the transmission and the input shaft of the drive axle between the two shafts. The active fork is in horizontal position, and the plane of the bearing shaft of the turntable is perpendicular to the driven shaft. Velocity projection of the active fork to the cross plane. The bearing driven fork of the first universal joint is in the same plane as the active fork of the second universal joint. The rotation speed of main and slave moving shaft is off the bearing system. The greater the two axis intersection Angle, the greater the speed, the worse the inequality of the transmission shaft.
