Description

Technical Field

[0001] This utility model relates to the field of wheel hub bearing technology, specifically to a double-ended ABS non-directional mounting automotive wheel hub bearing. Background Technology

[0002] With the development of automotive electronics and intelligence, anti-lock braking systems (ABS) have become standard equipment in modern cars. Traditional wheel bearings typically only have a magnetic seal with ABS signal installed on one side. If the installation orientation is incorrect during maintenance or replacement, the ABS signal will fail, affecting driving safety. Furthermore, existing magnetic seal materials (such as SPCC matrix + NBR rubber) suffer from problems such as easy wear, insufficient temperature resistance, and poor rust resistance, affecting the reliability and service life of the bearing.

[0003] Industry pain points:

[0004] a. Strong dependence on installation direction: Traditional bearings only have ABS signal on one end, which makes them easy to install backwards during maintenance, causing the ABS signal to fail.

[0005] b. Insufficient material properties:

[0006] - The magnetic ring substrate (SPCC) is prone to rust and has a high surface roughness, which accelerates the wear of the sealing lip.

[0007] - The sealing ring rubber (NBR) has a narrow temperature range (-30℃~100℃) and is prone to aging at high temperatures.

[0008] c. Low sealing reliability: Existing sealing structures are susceptible to contamination or grease leakage, affecting bearing life.

[0009] Necessity of research:

[0010] a. Improved installation error tolerance: The double-ended ABS design allows for installation in any direction, reducing the maintenance error rate.

[0011] b. Enhance material properties:

[0012] - Made with SUS430 stainless steel base, improving rust resistance and reducing surface roughness.

[0013] - The upgraded rubber material is HNBR (hydrogenated nitrile rubber), which extends the temperature range to -40℃ to 150℃.

[0014] c. Optimized sealing system: Multi-cavity contact sealing structure improves the ability to prevent dirt and grease leakage. Summary of the Invention

[0015] This invention addresses the shortcomings of existing technologies by providing a double-ended ABS non-directional mounting automotive wheel hub bearing, characterized by its simple structure, convenient assembly, and long service life. The double-ended ABS non-directional mounting structure solves the assembly direction problem, allowing installation from both ends and reducing maintenance errors. The magnetic sealing ring structure uses high-performance materials to improve corrosion resistance, wear resistance, and temperature resistance.

[0016] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

[0017] A dual-end ABS non-directional mounting automotive wheel bearing includes a wheel bearing with a mudguard cooling bushing nested within it for positioning. The wheel bearing includes an outer ring, within which are a pair of mirror-symmetrically distributed inner rings that are movably nested. Magnetic sealing rings are provided between both ends of the outer ring and the inner rings. The mudguard cooling bushing includes a bushing with a mudguard outer ring at its front end. A plurality of annularly distributed mudguard rods are provided between the mudguard outer ring and the bushing.

[0018] Preferably, the magnetic sealing ring includes a magnetic ring nested within the inner ring, and a multi-lip sealing ring is provided between the magnetic ring and the outer ring.

[0019] Preferably, the multi-lip sealing ring includes a multi-lip sealing rubber ring made of hydrogenated nitrile rubber (HNBR), and a sealing ring skeleton ring is provided between the multi-lip sealing rubber ring and the outer ring to interlock and support the multi-lip sealing rubber ring.

[0020] The standard multi-lip seal is made of SPCC + NBR (nitrile butadiene rubber). The rubber material is NBR, a standard nitrile butadiene rubber, with an operating temperature of -30℃ to 100℃. Bearings are prone to aging in high and low temperature environments. By changing the rubber to hydrogenated nitrile butadiene rubber (HNBR), the operating temperature is reduced to -40℃ to 150℃. This effectively prevents the seal from aging in high and low temperature environments, thereby improving product quality.

[0021] Preferably, the magnetic ring includes a magnetic skeleton ring located between the multi-lip sealing ring and the inner ring, and a magnetic substrate is provided on the outer end face of the magnetic skeleton ring.

[0022] Ordinary magnetic rings are made of SPCC + NBR (nitrile rubber) + magnetic material, with SPCC as the base material. This material has a large surface roughness, making the sealing ring lip easy to wear and lacking rust prevention. The magnetic base material of the magnetic ring is SUS430, which has a lower surface roughness, making the sealing ring lip less prone to wear and providing rust prevention.

[0023] Preferably, a retainer is provided between the outer ring and the inner ring, and the retainer is provided with a number of steel balls that are movably engaged with the retainer.

[0024] Preferably, one side of the wheel hub bearing is provided with a pair of retaining rings with a semi-circular structure that are nested and inserted into the mudguard cooling bushing.

[0025] Preferably, the inner wall of the bushing is provided with several spline grooves that are distributed in a ring and pass through both ends of the bushing.

[0026] This invention can achieve the following effects:

[0027] This invention provides a double-ended ABS non-directional mounting automotive wheel hub bearing, which, compared with existing technologies, features a simple structure, convenient assembly, and long service life. The double-ended ABS non-directional mounting structure solves the assembly direction problem, allowing installation from both ends and reducing maintenance error rates. The magnetic sealing ring structure uses high-performance materials to improve corrosion resistance, wear resistance, and temperature resistance.

[0028] Ordinary products with ABS signals typically have an ABS signal magnetic seal on one side of the bearing. However, during installation by end-customers, technicians may lack expertise and confuse the installation orientation of both ends of the bearing, leading to incorrect installation and triggering the ABS signal alarm. Therefore, designing and developing a product with ABS signals on both sides is crucial. This would allow customers to install the product even if they are not familiar with the orientation, thus requiring less skill from the technicians and ensuring product quality.
