The half shaft, also called the drive shaft, is the variable box reducer and the drive wheel to transfer torque shaft, its inner and outer ends each have a universal connection with the reducer gear and hub bearing inner ring through the spline on the universal joint. It is usually solid, but with hollow shafts it is easier to control unbalance, so cars use hollow shafts more often. Automobile semi-axle bushing is made of high quality carbon structural steel and alloy structural steel hot rolled seamless steel pipe for automobile semi-axle bushing and drive axle housing shaft tube.
According to the different supporting types of the commonly used semi-axle of modern cars, there are two kinds of fully floating and semi-floating.
Full floating axle: only transfer torque, do not bear any reaction force and bending moment, so widely used in all kinds of cars. The full floating half shaft is easy to disassemble, only need to screw down the bolts on the edge of the half axon can be pulled out of the half shaft, and the wheels and axle housing can still support the car, so as to bring convenience to the car maintenance.
Semi - floating semi - shaft: both transfer torque and withstand all reaction and bending moment. Its support structure is simple and cost is low, so it is widely used in all kinds of cars with small reaction bending moment. However, this kind of half-shaft support is difficult to remove, and if the half-shaft is broken in driving, it is easy to cause the danger of wheel flying off.
used to connect two shafts in different institutions (drive shaft and driven shaft), so that they rotate together, to transfer torque mechanical parts. In high speed and heavy load power transmission, some couplings also have the function of buffering, damping and improving the dynamic performance of shafting. The coupling consists of two halves connected with the driving shaft and the driven shaft respectively. General power machines are usually connected with working machines by means of couplings.
◾ Whether there is a transmission device between the prime mover and the universal coupling
◾ prime mover type and optional universal coupling load transfer category
◾ consider the prime mover's working environment
◾ joint form and installation of both ends of universal coupling
◾ The speed of the universal coupling itself
◾ Check whether the installation position is limited
