What is the used of stub axle?
A stub axle or stud axle is either one of two front axles in a rear wheel drive vehicle, or one of the two rear axles in a front wheel drive vehicle. In a rear wheel drive vehicle this axle is capable of angular movement about the kingpin for steering the vehicle.
How do stub axles work?
A stub axle is a sub-assembly of a front 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 light drive fit in the axle beam eye, located and locked by the taper cotter pin.
Where is the stub axle located?
Stub Axle: Stub axles are attached to the vehicle’s front wheels, with kingpins connecting these axles to the front axle.
What are stub axles made from?
For maximum strength to weight ratio, a stub axle needs to be forged from steel. Forging will allow the stretched fibres in the steel to follow the lines that will carry load when in operation. You could start with a short round bar. Upset or spread one end to make the flange, while thinning and lengthening the shaft.
How do you weld a stub axle?
Tack weld through the plug weld holes to secure the back end of the stub axle. Set your welder up so that you can lay a good hot penetrating weld (practice on some scrap steel) and fully weld around the stub axle and axle tube. Fill the plug weld holes up until the weld is flush with the top of the axle tube.
What are the types of front axle?
There is two types of front axles: (a) Dead front axle, and (b) Line front axle. Dead axles are those axles, which donet rotate. These axles have sufficient rigidity and strength to take the weight. The ends of front axle are suitably designed to accommodate stub axles.
How do I make my trailer axles wider?
If the entire trailer needs to be wider, simply split the trailer down the middle (front to back). Cut all the cross members and add middle sections. Of course, this will also require a new axle because the spring seat distance and track width must get wider.
Where should the axles be on a trailer?
When positioning a trailer axle or adding an additional axle, the key is to make sure that the axles are located in just the right position so that roughly 10 to 15 percent of the total trailer weight is placed on the tongue.
How does a front axle work?
Modern front -wheel drive cars typically combine the transmission (gearbox and differential) and front axle into a single unit called a transaxle. Each half axle connects to the wheel by use of a constant velocity (CV) joint which allows the wheel assembly to move freely vertically as well as to pivot when making turns.
What causes a broken axle?
A vehicle does not get far, or anywhere if it has a damaged drive axle. Axles are rods or shafts that connect to the drive wheels. Even though axles are built to be tough, an overloaded vehicle can sometimes crack or break an axle. Bad carrier bearings or bad potholes are other common causes of axle problems.
What is a four axle vehicle?
Now for a 4 axle vehicle, is a vehicle with 4 axles. The examples would be a Tri-drive highway tractor which is used for oversize loads, a dump truck that has a lift axle, or a concrete mixer which has two steer axles and two drive axles.
How many axles does a 4 wheel drive have?
Four-wheel drive (4WD) refers to vehicles with two axles providing torque to four axle ends. In the North American market, the term generally refers to a system optimized for off-road driving conditions.
What is axle drop in a front axle?
A dropped axle is a straight front axle that has been altered or built to drop a vehicle’s ride height. This makes the vehicle sit lower and places the front suspension nearer to the ground.
What is a stub shaft?
These bearing supported stub shafts allow side-load to the back of an engine while simultaneously preventing any load transmission back to the crankshaft. Many industrial engines do not allow side loads on their engine crank shafts (pulley applications) but this is a suitable solution to a common problem.
What is the type of section at the end of the front axle?
The front axle is made up of a circular or elliptical section at the ends and I- section in the middle portion. This cross- section of the axle withstands bending loads due to the weight of the vehicle and torque applied due to braking. Now let’s discuss types of front axles in detail.
