The car half shaft is also called the drive axle, and the inner end is connected with the half shaft gear through the spline.The half shaft is a solid shaft that transmits torque between the differential and the drive wheel.The half-shafts commonly used in modern automobiles have two types, full-floating and semi-floating, according to their different bearing types.
The full-floating half-shaft only transmits torque, and does not bear any reaction force or bending moment, so it is widely used in various automobiles.The full-floating half-axle is easy to disassemble and assemble. The half-axle can be drawn out by simply unscrewing the bolts on the flange of the half-axle. The wheels and axle housing can still support the car, thus bringing convenience to car maintenance.
The semi-floating half shaft not only transmits torque but also bears all reaction forces and bending moments.Its supporting structure is simple and low in cost, so it is widely used in all kinds of cars with small reaction force and bending moment.However, this kind of half-shaft support is troublesome to dismantle, and if the half-shaft breaks during driving, it is easy to cause the danger of wheels flying off.
