​Parts Of Wheel Assembly You Must Know About

11th Jul 2023

Wheels are unarguably one of the most crucial elements of a vehicle. Whether you're riding a car or a heavy-duty vehicle such as a truck or tractor, wheels must be properly installed onto the tire to provide easy maneuvering. Wheel assembly looks like an easy-to-do task—pop on the wheel using a torque wrench, tighten the lug nuts, and you’re on your way to a merry drive again.

But do you know about the various parts and their functions comprising the wheels and tire assembly? Let’s explore further and learn about it.

What is wheel hub assembly?

Wheel hub assembly refers to the pre-assembled unit that comprises various crucial mechanical elements, such as precision bearings, sensors, seals, etc. It is responsible for attaching the tires and wheels to the vehicle. It is an essential part of the vehicle's steering system that ensures safety and stability.

The wheel hub assembly is located on each wheel between the drive axle and the brake discs. On the side of the brake discs, the wheel is attached to the bolts of the wheel hub assembly, whereas on the side of the axle, it is mounted on the steering knuckle.

What are the different parts of the wheel hub assembly?

• Bearings: They are generally available in the form of balls and tapers and are a crucial component of wheel assembly. It rides on the shaft of the axle and fits into the hub. They withstand the torque received from the vehicle during the ride and are prone to be worn out quicker than any other component.
• Hub: There can't be a wheel hub assembly without the wheel hub. It is the skeleton of the entire ensemble. It is responsible for connecting the wheel to the axle of the vehicle. The wheel hub provides inlets for the bearings. Together they form a compact structure. When the bearings fail, the wheel hub provides additional support for some time before wearing out.
• Rotor: Rotors help to halt the vehicle to a stop when you apply brakes. The brakes, are connected with the calipers present on the wheels; pressing the brakes causes the calipers to squeeze on the brake pads against the rotors of the vehicle. This causes friction between the two and stops the spinning motion of the wheels.
• Seals: The function of this component is self-explanatory. The seals are attached between the bearings and the axle and prevent the entry of unwanted substances into these components. They are designed to store grease for lubrication of the bearings, which allows smoother functioning of the hub assembly without the harmful effects of friction.

Wheel assembly pertains to the proper functioning of the vehicles. Certain signs and symptoms can help you determine whether your wheel hub assembly requires a replacement or not. For example, if you're hearing a grinding sound from your vehicle, the vehicle's bearing is probably wearing out and needs replacement.

Purchasing vehicle parts from a trusted dealer is a wise decision when looking for a replacement. Several leading companies, such as Forklift Tire Company, provide top-notch vehicle parts that guarantee high quality at the best prices.
