SINOTRUK HOWO AZ9981340309 Rear Wheel Hub Assembly

• It is an integral part of the vehicle's rear wheel system.

• Material: Usually made of high-quality metal materials such as steel or aluminum alloy, which are strong and durable.

• Design: Comprises a hub body, bearings, and other components. The hub body provides a mounting surface for the wheel and houses the bearings that allow the wheel to rotate smoothly.

• Load-bearing Capacity: Capable of withstanding the weight and forces exerted by the vehicle and cargo.

• Reliability: Ensures stable and reliable operation of the rear wheels, reducing the risk of breakdowns.

• Wheel Mounting: Serves as the mounting point for the rear wheel, holding it in place and allowing it to rotate.

• Transmission of Power: Transmits power from the drive train to the rear wheels, enabling the vehicle to move.

• Stability and Balance: Contributes to the overall stability and balance of the vehicle by providing a solid connection between the wheel and the vehicle's chassis

Product Advantages & Features

(1) The wheel hub is made of QT450 material.
(2) The CNC machine tool performs rough machining, and the machining center performs fine machining and drilling.
(3) Single inspection and delivery to ensure product stability.

Working Principle

Drum brake is mainly composed of brake bottom plate, brake drum, brake shoe, return spring, compression wheel and other components.
During braking, by pedaling and using the lever principle, the force of the push rod is applied to the brake master cylinder. After the pressure of the brake fluid is amplified and the brake slave cylinder is pushed, the pistons at both ends of the brake slave cylinder will simultanseously push the same force to the shoe ends of the left and right brake shoes, and the other ends of the two brake shoes are supported by the support rod. At this time, the two brake shoes expand outward, and it fits with the inner surface of the brake drum to form friction, so as to achieve the purpose of braking. As the wheel is a rotating brake drum, the pressure acting on the brake shoe is asymmetric, resulting in self-increasing force and self-decreasing force. The friction torque of the force increasing brake shoe is 2 ~ 2.5 times that of the force reducing brake shoe, resulting in different wear degrees of the two brake shoe
