轮毂法兰

A precision-machined flange connecting the wheel hub to the axle or brake assembly in automotive systems.

技术定义与适配语境
典型 轮毂法兰 会按材料、尺寸公差、适配关系和失效风险在 汽车制造 中评估。

The hub flange is a critical rotating component in wheel hub assemblies that provides a mounting surface for wheel studs or bolts, facilitates connection to the axle shaft or brake rotor, and ensures proper alignment and load distribution. It transmits torque from the axle to the wheel while withstanding radial, axial, and bending forces during vehicle operation.

定义
The hub flange is a critical rotating component in wheel hub assemblies that provides a mounting surface for wheel studs or bolts, facilitates connection to the axle shaft or brake rotor, and ensures proper alignment and load distribution. It transmits torque from the axle to the wheel while withstanding radial, axial, and bending forces during vehicle operation.
工作原理
The hub flange operates by creating a rigid interface between the wheel hub and connected components. It uses precisely positioned studs or bolt holes to secure the wheel, while its machined surfaces maintain concentricity with the axle. During rotation, it distributes vehicular loads evenly and provides a sealing surface for bearings.
材料
Typically forged or cast steel (e.g.SAE 1045AISI 4140)sometimes alloy steel or aluminum for lightweight applications. Heat-treated to HRC 28-35 for strength. Surface treatments may include zinc plating or phosphate coating for corrosion resistance.
Load Capacity
800-1500 kg per stud
Flange Thickness
15-25 mm
Runout Tolerance
<0.05 mm
Stud Thread Size
M12x1.5 to M14x1.5
Bolt Circle Diameter
100-150 mm
标准
ISO 4107DIN 743SAE J429

常见问题

What is the primary function of a hub flange?

To securely connect the wheel to the axle while maintaining precise alignment and distributing mechanical loads.

Can hub flanges be interchanged between vehicle models?

No, they are model-specific due to variations in bolt patterns, dimensions, and load requirements.

What are common signs of hub flange failure?

Vibration during braking, uneven tire wear, loose wheel feel, or visible cracks around stud holes.
