Axle (Driver Shaft) is also called a drive shaft (CVJ).
axis of axle torque is transmitted between the reduction gear transmission and drive wheels (mostly solid before, but due to the unbalanced rotation of the hollow shaft easier to control, and therefore, have many cars hollow shaft), each of the inner and outer ends there is a section (U / jOINT) are splined to the gear reducer and the bearing inner race on the hub by a universal joint.
Modern automotive common axle, which is supported in accordance with the different types, there are semi-floating and full-floating two.
full floating axle shafts only transmit torque, does not bear any reaction force and moment, with independent suspension with help to improve the comfort of the vehicle, which is widely used on various types of vehicles. Full floating axle easy disassembly, simply unscrew the bolt fixed axle when the axle maintenance to be pulled out, and wheel and axle can still support the car, so as to bring convenience to car maintenance.
both semi-floating axle receiving and transmitting all the torque reaction force and moment. It has a simple support structure, low cost, mainly used in less demanding on the comfort of pickup and SUV vehicle. However, this axle bearing cannibalized cumbersome, and if the car driving axle is easy to break off the dangerous flying wheel, to be phased out in the form of belonging.
