The types of Front Axle includes Dead Front Axle that stays in place, not rotating with the wheels, and Live Front Axle delivers driving power from gearbox to front wheels. Stub Axle: are attached to the car's front wheels.
Kingpins connect these axles to the front axle. The kinds of Stub Axle include Elliot uses yoke, kingpin and cotter connecting to the front axle , Reverse Eliot as the name suggests has opposite arrangement compared to standard Elliot , Lamoine with L-shape spindle instead of yoke type hinge , and Reverse Lamoine with opposite arrangement compared to standard Lamone.
Rear Axle: delivers power to the driving wheels and comes in two halves, called half shafts that are connected by the differential. In the majority of cases, rear axles are live, which means they rotate with the vehicle's wheels. There are also other types of rear axles as determined by the support and the mounting methods. This kind of axle has two. One supports the axle shaft, while the other one goes inside the axle casing.
Having two bearings means a semi-floating axle has to be larger than the other types to produce the same torque. These axles are used for SUVs, cars and mid-size trucks, like half-ton and light duty pickups. The Full-Floating Axle as its name suggests efficiently floats in place maintaining its position, thanks to having two bearings.
It transmits driving torque only and tends to work best for bigger vehicles like heavy-duty trucks, some mid-size trucks with larger towing capacities or vehicles with four-wheel drive.
Full-floating axles are designed for vehicles that need to handle extremely severe driving conditions or those that need to carry heavy loads. These axles in support of their function are not only quite heavy but also durable. Its torque is also transmitted through a separate weightless axle shaft.
These axles are able to bear the weight and transfer torque, while weighing much less. A Three-Quarter Floating Axle is more complex and reliable than semi-floating axles. It aids in maintaining wheel alignment and in handling side thrust and driving torque. If that is not enough, axles are further classified as drive axles or dead axles. The drive axle extends from the differential up to the tire.
They are typically encased within an axle housing that offers it more protection and allows for it to operate much more effectively. However, the majority of rear axles that are used with cars are live.
Based on the mounting process and the kind of support it gives, rear axles are classified into three. They are the semi-floating axle, the full floating axle, and the three-quarter floating axle. Front axles require stub axle. They are mounted on a stub axle to ensure the steering works efficiently. With the aid of kingpins, the stub axles stay connected to the front axles. There are four types of stub axles. When it comes to vehicles, they are sometimes referred to by the number of axles they have on certain highways.
A 2-axle vehicle is what it is. In essence, it has two axles one in the front and another at the back. That is why it is called a 2-axle vehicle. A 3-axle vehicle is called so because it has three axles. That is, one axle is located in the front, and the other two axles sit behind. A 4-axle vehicle is what you now think it is. It has four-axle that are either distributed evenly other unevenly. For instance, a 4-axle vehicle could either have two axles in front and two at the rear or one axle in the front and the remaining three at the rear.
Now that you know what axles are, you can now understand the discussion topic when used in a conversation. Nevertheless, beyond knowing what axles are and the number of axels your car has, you need to understand their impact on your car too. Although axles are made from durable materials, they can start to fail from either overuse or stress. James is a certified auto technician specializing in commercial vehicles.
Several factors determine what type of axle a vehicle needs. For example, the technical requirements and the amount of force produced go a long way in deciding the axle type. Some vehicles have pre-designed axles in standard formats. Others have customized axles that fit the needs and specifications of the car. Customized axles tend to work best for cars since they allow for more personalized control over the wheels.
These axles can adjust the wheels' speed and torque to a finer degree. Axles come in three standard types, according to Quadratec :. Not all rear axles are the same, as the support and mounting methods determine the type.
According to The Engineers Post , there are three types of rear axles:. According to Meineke , vehicles have two main types of front axle. These are:. Because axles are essential to your car's operation, it's important to keep them working properly. As Meineke states, if you see one of the following signs, you can tell that your axle is in disrepair:. In addition to unique torque, motor, and transmission specs, many trucks also have custom axle ratios.
According to Edmunds , an axle ratio like 3. In most cases, a standard axle ratio works well for most drivers who don't expect to haul large loads. However, if you're planning to tow heavy trailers or haul large loads, you may want the highest axle ratio possible. When choosing the right axle ratio for your vehicle, keep a few things in mind. Axles are just one of the features that are essential for keeping your car on the road. Learn more about our favorite cutting-edge features in our comparison tests and first drive reviews.
Trucks are a more complicated vehicle because they differ in size and the number of tires they need. Because of the weight they carry, their front axles are made of old solid axles. If the axle is broken completely, you might not have control of the vehicle and might crash into other vehicles.
From what has been discussed above, the number of axles in a vehicle will differ based on many factors. If you want to find out how many axles your vehicle has, you can inspect the vehicle on your own. Hi, I'm the founder of VehicleAnswers. Having owned a wide variety of vehicles in my life, I was astounded at how hard it can be to find answers to common automotive questions. Rather than sit idly, I decided to create this website to help others!
So how many axles does a car have? When the wheels are revolving smoothly, that means that the axle is operating optimally. How many axles does an SUV have?
