Universal joint structure
Dec 10, 2018

The universal joint refers to the use of a ball type device to achieve shaft power output in different directions, which is a very important part of the car. The universal joint is combined with the drive shaft and is called a universal joint transmission. In front-engine rear-wheel drive vehicles, the universal joint transmission is installed between the transmission output shaft and the transaxle final drive input shaft; while the front engine front-wheel drive vehicle omits the drive shaft, universal joint installation Between the axle axle and the wheel, both the drive and the steering.


In automotive drive trains and other systems, in order to achieve power transfer between the shafts where the axes intersect or the relative positions change frequently, a universal joint must be used. The universal joint transmission generally consists of a universal joint and a transmission shaft, and sometimes has an intermediate support, which is mainly used for the following positions: 1- universal joint; 2-drive shaft; 3- front drive shaft; 4-intermediate support


The front and rear wheels of the engine drive the transmission between the car and the transaxle. When the distance between the transmission and the transaxle is far, the drive shaft should be divided into two sections or even multiple sections, and an intermediate support should be added. Multi-axis driven car between the transfer case and the drive axle or between the drive axle and the drive axle. Due to the deformation of the frame, it is caused between the two transmission members whose positions are mutually changed between the axes.
