Wheel hub: The wheel hub, also known as the wheel rim, wheel cover, or wheel hub, is a barrel-shaped structure that supports the tire's inner contour. The central metal part is mounted on the axle. Wheel hubs are classified into many different types based on their diameter, width, forming method, and materials used.
Wheel Hub: Also known as a wheel rim, wheel cover, or wheel hub, the wheel hub is a barrel-shaped structure that supports the tire's inner contour. The central metal part is mounted on the axle. Wheel hubs are categorized into many different types based on diameter, width, forming method, and material used.
Generally, they are classified into baked paint and electroplated types. For ordinary vehicles, when choosing wheel hubs, the main consideration is whether the heat dissipation is good, and the appearance is not a major concern. The process generally uses baked paint processing, which involves spraying and baking, making it relatively economical, with beautiful colors and long-lasting preservation.
Brake Drum: The brake drum is the friction pair of the drum brake in a drum brake system. It has a high and stable friction coefficient, appropriate wear resistance, heat resistance, heat dissipation, and heat capacity, as well as relatively high strength and rigidity; however, it becomes brittle after aging.
The brake drum is an important component of the drum brake, similar to the brake disc in a disc brake system. During braking, the piston applies pressure to the two crescent-shaped shoes, causing them to press against the inner wall of the drum, thus generating friction to stop the rotation of the wheel.
