REAR AXLE
REAR AXLE Construction: It is mostly live axle in commercial vehicles and dead axle in cars. Two half-shafts are used to transmit the power from differential. FORCES ON REAR AXLE 1. Shear stress due to weight of the body 2. Driving Thrust During torque transmission the thrust has to be transmitted to body through frame by radius rod. 3. Torque reaction Torque reaction will be there during torque transmission and braking. This will oppose the propeller shaft rotation causing torsional and bending stress. 4. Side Thrust Side thrust or pull due to side load on the wheel and due to cross winds during cornering. Types of Rear axles Depending upon the method of supporting the rear axles and mounting the rear wheels 1.Semi or non-floating axle 2.Full-floating axle 3.3/4 Floating axle 1.Semi floating axle Half-shaft inner end is splined into the differential and other end is supported by bearing inside casing.
