Universal Joint, which is an important part of the automobile, is a kind of device that can realize the power output of the shaft in different directions. Universal joint and transmission shaft combination, known as universal joint transmission device. In a vehicle with a front-mounted rear-wheel drive, the universal-joint transmission is mounted between the transmission output shaft and the drive axle input shaft of the main reducer, the universal joint is mounted between the front axle half shaft, which is responsible for driving and steering, and the wheels. Below you to introduce the structure of the universal joint, the impact factors and maintenance methods. Universal joint structure, influencing factors and maintenance methods, structure, in the automobile transmission system and other systems, in order to achieve some axis intersection or the relative position often change between the rotating shaft, must use universal transmission device. Universal drive is generally composed of universal joints and transmission shaft, sometimes also have intermediate support, mainly used in the following locations: 1-universal joints, 2-transmission shaft, 3-front transmission shaft; 4-intermediate support between the front-mounted rear-wheel drive vehicle's transmission and the drive axle. When the distance between transmission and drive axle is far, the drive shaft should be divided into two or even more sections, and the middle support should be added. A multi-axle drive vehicle is provided between the transfer and the drive axle or between the drive axle and the drive axle. Because of the deformation of the frame, the axis will cause the change in position between the two transmission parts. Between the differential and the car with independent suspension. Steering Drive axle differential and wheel. In the power output device and steering control mechanism of an automobile. The factors that influence the balance of the universal joint without correction are as follows: 1. The unbalance caused by the manufacturing tolerance stipulated in the design specification of the main part of the universal coupling. 2. The unbalance caused by the eccentricity of the central face of the universal joint and the shaft. 3. Clearance between mating parts in universal joints. 4. Unbalance caused by uneven or asymmetrical distribution of accessories in universal joints. 5. Unbalance caused by uneven material or uneven wear of the parts of the universal joint. Universal joint structure, influencing factors and maintenance methods, maintenance methods, universal joint cross shaft maintenance needs to grind gear oil, because the lubricating nozzle of the needle roller bearing of universal joint cross shaft is an ordinary butter nozzle, so it gives people a kind of illusion, it has long been common to add butter for lubrication. In fact, from the butter nozzle is difficult to add butter to the needle roller bearings, and even cross-bearing face is very difficult to achieve. Lubrication with butter (i. e. calcium-based Grease) can cause early damage to a large number of needle roller bearings.
