What is the Brake drum:
The brake drum is a type of cast iron shaped like a tambourine, which is fixed with the tire and rotates at the same speed. When braking, apply oil pressure to push the brake shoes to contact the brake drum inner rim, we can control the rotation of the wheel to achieve the purpose of braking by the friction force comes from contact.
Structure of drum brakes
Drum brakes are a brake system with brake drums (rotor) which rotate with the wheels. Inside each drum are
brake shoes fitted with brake linings (friction material). Pistons (pressure mechanism) press against the drums
from the inside to generate braking force, thus making is possible to decelerate and stop the vehicle.

How drum brakes work
When the driver steps on the brake pedal, the power is amplified by the brake booster (servo system) and
changed into hydraulic pressure (oil-pressure) by the master cylinder. The pressure reaches the brakes on
the wheels via tubing filled with brake oil (brake fluid). The delivered pressure pushes the pistons on the
brakes of the 4 wheels. The pistons press the brake linings, which are friction materials, against the inside surfaces of the brake drums which rotate with the wheels. The linings are pressed on the rotating drums,
which in turn decelerate the wheels, thereby slowing down and stopping the vehicle.

What is the primary function of an axle hub in a vehicle’s wheel assembly?
The primary function of an axle hub in a vehicle’s wheel assembly is to connect the wheel to the axle and provide a mounting point for the wheel bearings. Here’s a detailed explanation of the primary functions of an axle hub:
1. Wheel Mounting:
The axle hub serves as the component that connects the wheel to the vehicle’s axle. It is typically a cylindrical or disc-shaped structure located at the center of the wheel assembly. The hub contains bolt holes or studs that align with the corresponding holes or studs on the wheel, allowing for secure attachment and proper alignment of the wheel.
2. Bearing Support:
The axle hub provides a mounting point for the wheel bearings. Wheel bearings are crucial components that allow the wheel to rotate smoothly while supporting the weight of the vehicle. The hub contains a bearing race or races, which are machined surfaces that support the inner and outer wheel bearings. The bearings fit snugly into the hub and enable the wheel to rotate freely around the axle.
3. Load Transmission:
Another important function of the axle hub is to transmit the load from the wheel to the axle. As the vehicle moves, various forces act on the wheel, including the weight of the vehicle, acceleration and braking forces, and lateral forces during turns. The axle hub, along with the wheel bearings, helps distribute and transfer these forces from the wheel to the axle, allowing for smooth and controlled movement of the vehicle.
4. Hub Assembly Integration:
In many vehicles, the axle hub integrates with other components of the wheel assembly. For example, it may have provisions for attaching the brake rotor or drum, which are essential for the vehicle’s braking system. In vehicles with front-wheel drive or all-wheel drive, the axle hub may also incorporate features for connecting the CV (constant velocity) joint or driveshaft, allowing for power transmission to the wheels.
5. Wheel Alignment:
The axle hub plays a role in maintaining proper wheel alignment. The hub’s design and dimensions are critical in ensuring that the wheel is centered and aligned correctly with the vehicle’s suspension system. Proper wheel alignment is essential for optimal handling, tire wear, and overall vehicle performance.
In summary, the primary function of an axle hub in a vehicle’s wheel assembly is to connect the wheel to the axle and provide a mounting point for the wheel bearings. It facilitates the secure attachment of the wheel, supports the wheel bearings for smooth rotation, transmits loads from the wheel to the axle, integrates with other components of the wheel assembly, and contributes to proper wheel alignment. The axle hub is a critical component that enables safe and efficient operation of the vehicle’s wheels.
