Description

Technical Field

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

[0002] The wheel hub bearing unit is one of the key components of an automobile. Its main function is to bear weight and provide precise guidance for the rotation of the wheel hub, which requires it to withstand not only axial loads but also radial loads. However, current vehicles use flange connections between the wheel hub unit and the chassis and suspension, making it impossible to adjust the center distance between the wheel hubs at both ends of the vehicle. This often results in a difference in the left-right weight distribution of the vehicle, causing outward or inward drift when cornering, requiring the driver to adjust the direction accordingly. Summary of the Invention

[0003] This invention primarily addresses the shortcomings of existing technologies by providing a wheel hub unit structure that enhances safety. This structure features a compact design, adjustable lateral wheel hub spacing, high structural strength, and good operational stability. By fine-tuning the lateral wheel hub unit spacing, it solves the problem of vehicle cornering safety. This improves the safety and reliability of vehicle cornering and prevents excessive deviation during cornering that could cause scraping.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

[0005] A wheel hub unit structure for improving safety includes a wheel hub unit, a guide rail rod at the upper end of the wheel hub unit, a guide block fixed to the wheel hub unit and slidably inserted with the guide rail rod between the guide rail rod and the wheel hub unit, a transverse adjustment cylinder at the lower end of the wheel hub unit, and a sliding plate between the transverse adjustment cylinder and the wheel hub unit.

[0006] The guide rail has a guide groove inside that engages with the guide block for positioning. The guide block and the outer ring are integrally welded or cast, ensuring the integrity and stability of the structure. The guide block is fixed to the hub unit and simultaneously slides into the guide rail. This design achieves precise guidance during sliding while reducing friction and wear.

[0007] Preferably, the hub unit includes a flange, on which an outer ring is slidably fitted, and between the outer ring and the flange, a pair of inner rings are provided in a mirror-symmetrical arrangement. A retainer is provided between the inner ring and the outer ring, and a plurality of steel balls are provided in a ring arrangement and are rolled and engaged with the retainer.

[0008] Preferably, a dustproof skeleton sealing ring is provided between the inner end of the outer ring and the inner ring, and a magnetic skeleton sealing ring is provided between the outer end of the outer ring and the inner ring.

[0009] Preferably, an arc-shaped support block is provided between the sliding plate and the outer ring, and is screwed and fixed to both the outer ring and the sliding plate. The arc-shaped support block between the sliding plate and the outer ring, fixed by screws, enhances the sealing of the structure and prevents external impurities from entering.

[0010] Preferably, the guide block and the outer ring are integrally welded or integrally cast.

[0011] Preferably, the flange has a splined shaft hole for insertion and connection with the drive shaft.

[0012] Preferably, the guide rail rod is provided with a guide groove that is limited and inserted into the guide block.

[0013] Preferably, the cross-sections of the guide block and the guide groove are T-shaped. The T-shaped cross-sections of the guide block and guide groove provide higher bending strength and limiting accuracy, making them suitable for applications subject to complex loads.

[0014] This invention can achieve the following effects:

[0015] This invention provides a wheel hub unit structure that enhances safety. Compared with existing technologies, it features a compact structure, adjustable left-right wheel hub spacing, high structural strength, and good operational stability. By fine-tuning the left-right spacing of the wheel hub unit, the problem of vehicle cornering safety is solved. This improves the safety and reliability of vehicle cornering and avoids excessive deviation during cornering that could cause scraping. Attached Figure Description
