What is Front Axle? – It is used to carry the weight of the front part of the vehicle as well as to facilitate steering and absorb shocks due to road surface variations. It is made of I-section in center position while the ends are made either circular or elliptical with the construction.

Classification Of Axle
1. Front Live Axle
The live axle receives power from the gearbox and transmits it to the road wheels. It is the axle containing the differential mechanism through which the engine power flows to the front of the wheels. For steering the front wheel, a constant velocity joint includes in the half shaft; these joints help in turning the stub axle around the kingpin.
2. Front Dead Axle
Is it just a dummy axle having no connection with the engine? These axles do not rotate with the driver when compared to live axles. The Dead front-axle has sufficient rigidity and strength to transmit the weight of the vehicle form the springs to the front wheels. The ends of the axle beam shape suitably to assemble the stub axle. Usually, manufacturers shape the terms of a part of the beams either as a yoke or a drilled hole on an unattractive surface to accommodate a swivel pin connecting the sub-axle portion of the assembly.
What Is Front Axle?
The front axle uses to carry the weight of the front part of the vehicle as well as to facilitate steering and absorb shocks due to road surface variations. The construction makes the ends of the structure either circular or elliptical, while an I-section is used in the center position. It takes bending loads and also torques due to braking of the wheel. To keep the low chassis heights, its center portion gives a down-step sweep. Sometimes it also transmits torque from the differential to the drive wheels.

What Is Stub Axle?
A stub axle is a sub-assembly of a front Live axle beam upon which the road wheel mount. Stub axle is connected to the front-axle using kingpin. These stub axles turn about the kingpin, which is a light drive fit in the axle beam eye, located and locked by the taper cotter pin.Clutch.

Types Of Stub Axle
1. Elliot Stub Axle
This type of stub axle is attached to the front axle by placing it in the yoke end with a kingpin and a cotter to join the two together. The swivel pin is usually fixed in the stub axle forging with its purposes turning in the forced closing of the axle beam. The Axle beam forms as a yoke and receives stub axle. The thrust washer place at the top portion of the stub axle.

2. Reverse Elliot Stub Axle
The reverse Elliot type stub axle forms the fork end to receive the front axle beam. The front axle end forms eye, and the thrust washer placed at the bottom of the front axle beam that is at the contact face with the stub axle.
The cotter pin in the joint that locks the movement of the kingpin in the front axle. The kingpin is free to move in the phosphor bronze bushes placed in the eye of the fork end. The thrust washer takes vertical load in the joint and its used increases the life of both the stub axle and front axle. Stub axle forms as a yoke and receives the front axle. Thrust washer placed at the bottom.
3. Lamoine Stub Axle
The front axle beam end forms the eye to take support on the stub axle. The stub axle and kingpin integrates to create reverse. L shape assembly receives the front axle. The thrust washer place between the stub axle and front axle beam.
Here the cotter pin in the joint is used to lock the front axle in position. The kingpin is free to move in the bushes placed in the eye of the front axle. The thrust washer takes the vertical load in the joint.
4. Reverse Lamoine Stub Axle
The front axle beam-ends forms eye to take support the stub axle. The stub axle and kingpin integrate to form an inverted L shape assembly to receive the front axle. The thrust washer is placed at the bottom, as shown in the figure. The cotter pin in the joint use to lock the front axle in position. The kingpin is free to move in the bushes placed in the eye of the shaft. The thrust washer takes the vertical load, and it increases the life of both the stub axle and front axle.

2. Live Front-Axle
The road wheel mounts on a sub-assembly of a front-axle beam called a stub axle. A kingpin connects the stub axle to the front axle, and the stub axles turn around the kingpin, which fits lightly in the axle beam eye. Additionally, the taper cotter pin locates and locks the kingpin.
