Description

Technical Field

[0001] This utility model relates to the field of wheel hub bearing structure technology, specifically to a wheel hub unit with a damping structure. Background Technology

[0002] As an automotive component, the main function of the wheel hub unit is to bear weight and provide precise guidance for the rotation of the wheel hub. It bears both axial and radial loads. Integrating two sets of bearings into one unit offers advantages such as good assembly performance, elimination of clearance adjustment, light weight, compact structure, large load capacity, pre-lubrication of sealed bearings with grease, elimination of external hub seals, and maintenance-free operation. It is widely used in passenger cars and is showing a growing trend of application in heavy-duty trucks.

[0003] Wheel hub units are primarily used in automobiles. Developed from standard angular contact ball bearings and tapered roller bearings, they are commonly found in sports cars, sedans, and pickup trucks. When a vehicle turns or encounters uneven road surfaces, stress fatigue can accumulate in the steering arm, potentially leading to deformation and safety hazards. Summary of the Invention

[0004] This invention primarily addresses the shortcomings of existing technologies by providing a hub unit with a damping structure. This unit features a compact structure, excellent cushioning, and high operational stability.
