According to the different supporting forms of the drive shaft and the hub of the drive wheel on the axle housing and the force of the drive shaft, modern cars adopt two forms full floating drive shaft and a semi-floating drive shaft. The drive shaft of the common non-disconnected drive axle can be divided into three types: full floating, 3/4 floating, and semi-floating according to the different external support forms.

 

Fully floating drive shaft
Fully floating drive shafts are widely used in various types of trucks. The outer end of the drive shaft is provided with a flange plate directly forged; the hub is connected with the flange plate by bolts; the hub is supported on the drive shaft sleeve 1 through two tapered roller bearings that are far apart; the drive shaft sleeve is connected to the flange plate. The drive axle housing is press-fitted into one body, and the drive shaft has no direct connection with the drive axle housing. The two tapered roller bearings in the hub must be mounted in such a way that they can withstand inward and outward axial forces, respectively, to prevent axial displacement of the hub together with the drive shaft under lateral forces. Bearing preload can be adjusted by adjusting the nut and locked with a lock washer and lock nut.

 

Semi-floating drive shaft
The semi-floating drive shaft is mostly used in various types of cars. The inner end support of the drive shaft is the same as the full floating support, that is, the inner end of the drive shaft does not bear the bending moment. There are longitudinal key grooves and threads on the tapered surface of the outer end of the drive shaft. The hub is connected with the tapered portion of the drive shaft through a key and is fastened with a lock nut. The drive shaft is supported directly in the transaxle housing flange by tapered roller bearings. It can be seen that the reaction forces in all directions acting on the drive wheels by the road surface must be transmitted to the drive axle housing through the drive shaft. In addition to bearing radial force, the bearing also bears outward axial force. Therefore, a floating sleeve thrust block is arranged in the middle of the differential planetary bevel gear shaft, which can prevent the drive shaft from moving inward when the wheel is acted by an inward lateral force.

 

3/4 floating drive shaft
In addition to bearing the full torque, it also bears a part of the bending moment. The most prominent structural feature of the 3/4 floating drive shaft is that there is only one bearing at the outer end of the drive shaft, which supports the wheel hub. Due to the poor supporting rigidity of a bearing, this drive shaft not only bears the torque but also bears the bending moment caused by the vertical force, the driving force, and the lateral force between the wheel and the road surface. 3/4 floating drive shafts are rarely used in automobiles.
