The composition and application of automobile drive shaft

The transmission shaft is generally provided with a sliding spline consisting of a sliding fork and a spline shaft to achieve the change of the transmission length. In order to reduce the axial sliding resistance and wear of the sliding spline, sometimes the spline teeth are phosphated or sprayed with nylon layer; Some put the rolling element such as rolling needle, roller or ball in spend key groove, replace sliding friction with rolling friction, improve drive efficiency. But this kind of structure is more complicated, the cost is higher. Sometimes for severe impact load transmission, but also the use of elastic transmission shaft. The spline on the drive shaft should be lubricated and dustproof. The gap between the spline teeth and the keyway should not be too large, and the spline should be assembled according to the corresponding mark, so as not to damage the dynamic balance of the drive shaft assembly by wrong installation.

The length and Angle of the drive shaft and their variation range are determined by the overall layout design of the vehicle. The design should ensure that when the length of the transmission shaft is at a large value, the spline sleeve and shaft have enough matching length; And in the length is small does not die. The Angle of the drive shaft directly affects the life of the universal joint cross shaft and needle roller bearing, the efficiency of the universal transmission and the non-uniformity of the cross shaft rotation.

Drive shaft in a variety of different host products supporting the use of the surrounding working environment is more complex, such as temperature, humidity, water, steam, dust, sand, oil, acid, alkali, corrosive media, salt water, radiation and other conditions, is the choice of coupling must be considered one of the important factors. For high temperature, low temperature, oil, acid, alkali medium working quality, should not choose to general rubber as elastic element material flexible coupling, should choose metal elastic element flexible coupling, such as diaphragm coupling, snake spring coupling, etc.
