Description

Technical Field

[0001] This utility model relates to the field of wheel hub bearing technology, specifically a wheel hub bearing that is easy to install. Background Technology

[0002] As a core component of a vehicle's transmission system, wheel bearings bear the crucial functions of wheel rotation and load transmission, and their performance directly affects the vehicle's smoothness, safety, and service life. Traditional wheel bearings often suffer from the following technical challenges in their structural design:

[0003] 1. High installation complexity: Traditional bearings usually rely on multiple nested parts or interference fits for assembly, requiring special tools or complex procedures, making it difficult to quickly disassemble and maintain, especially when working in confined spaces where efficiency is low.

[0004] 2. Insufficient vibration and noise control: The lack of a flexible buffer structure between the rolling elements and the inner and outer rings makes it easy to generate vibration and noise due to hard contact during high-speed operation, which affects the ride comfort and accelerates the wear of parts.

[0005] 3. Weak axial stability: The axial positioning of the rolling balls relies on a single mechanical structure (such as a retaining ring or snap ring). Under long-term load, displacement and deviation are prone to occur, resulting in increased bearing clearance and affecting transmission accuracy.

[0006] 4. Limited expandability: Traditional flange designs are fixed and difficult to adapt to different installation scenarios or expand additional functional modules (such as sensor installation), resulting in insufficient flexibility.

[0007] To address the aforementioned issues, there is an urgent need for a new type of hub bearing that can simplify the installation process, improve structural stability and vibration resistance, and also accommodate modular expansion requirements. Utility Model Content

[0008] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a wheel hub bearing with modular structure, excellent buffering and shock absorption, and quick assembly and disassembly.

[0009] The technical solution adopted by this utility model to achieve the above objectives is as follows: a conveniently installed hub bearing, comprising an inner bearing sleeve, a first outer bearing sleeve, a second outer bearing sleeve, and a threaded ring. A limiting protrusion ring is provided in the middle of the outer ring of the inner bearing sleeve to separate the rolling structures on both sides and prevent axial displacement of the rolling balls. A retainer is provided on both sides of the limiting protrusion ring, and a plurality of rolling balls are installed within the retainer. The retainer constrains the arrangement of the rolling balls, which bear the load and achieve low-friction rolling. Bushing grooves are respectively formed on the inner bearing sleeve on both sides of the limiting protrusion ring, and inner bushing rings are fitted into each bushing groove. A rotating ring is rotatably connected to the outer ring of the limiting protrusion ring, and outer bushing rings are respectively connected to both sides of the rotating ring. The retainer and the rolling balls are rotatably connected between the inner bushing ring and the outer bushing ring. The bushing ring is used to restrict the movement path of the rolling balls, while improving the bearing's vibration damping and reducing noise. External threads are respectively formed on the bearing inner sleeve on the opposite side of the bushing groove, and internal threads are formed on the inner side of the threaded sleeve ring. The threaded sleeve ring is threadedly connected to the external threads at both ends of the bearing inner sleeve through its internal threads. The first bearing outer sleeve and the second bearing outer sleeve are respectively fitted onto both sides of the outer ring of the bearing inner sleeve. A first flange is fixedly connected to the first bearing outer sleeve located on the side of the second bearing outer sleeve, and a second flange is fixedly connected to the second bearing outer sleeve located on the side of the first flange. The first flange and the second flange are fixed to each other by bolts and nuts. The first bearing outer sleeve and the second bearing outer sleeve respectively wrap around the outer circumference of the bearing inner sleeve to provide external protection; and the bolt connection between the first flange and the second flange simplifies the overall assembly.

[0010] In the above technical solution, a nested groove is provided in the middle of the outer ring of the rotating ring, and two half-rings are connected in the nested groove. The two ends of the half-rings are respectively fixedly connected with clamping pieces. The first flange and the second flange are respectively symmetrically provided with clamping grooves, and the clamping pieces at both ends of the half-rings are respectively inserted into the clamping grooves.

[0011] In the above technical solution, a third flange is provided at the end of the first bearing outer sleeve that is away from the first flange.

[0012] In the above technical solution, an annular groove is formed on one side of the outer circumference of the threaded sleeve, and an annular guide groove is formed on the inner side of the annular groove. An inner sleeve is installed in the annular guide groove, and an outer sleeve is connected to the outer sleeve of the inner sleeve. The outer circumference of the outer sleeve abuts against the outer sleeve of the first bearing or the outer sleeve of the second bearing. A retaining ring is fixedly connected to the outer sleeve opening of both the first bearing outer sleeve and the second bearing outer sleeve. The retaining ring is rotatably connected to the annular groove.

[0013] In the above technical solution, both the inner liner and the outer liner are made of rubber.

[0014] The beneficial effects of this utility model are:

[0015] 1. Significantly Improved Installation Ease: This utility model utilizes the threaded connection design between the threaded sleeve ring and the bearing inner sleeve, combined with the bolt fixing structure of the first and second flanges, to achieve rapid alignment and locking without the need for complex tooling or interference fits, greatly shortening installation time. The insertion design of the semi-hoop ring and the slot further simplifies the positioning steps, reduces the risk of assembly deviation, and is especially suitable for confined spaces or field operation scenarios, significantly improving installation efficiency.

[0016] 2. Vibration Suppression and Noise Control Optimization: The inner and outer bushings are made of hard rubber, forming a flexible buffer layer between the rolling balls and the inner and outer sleeves, effectively absorbing high-frequency impacts and vibrations and reducing metal-to-metal contact noise. The linkage design between the rotating ring and the cage ensures stable movement of the rolling balls, reduces disordered collisions, and improves vehicle ride smoothness, making it especially suitable for heavy-duty or unpaved road conditions.

[0017] 3. Enhanced Axial Stability and Load-Bearing Capacity: The limiting protrusion ring separates the rolling structures on both sides, and combined with the axial locking effect of the threaded sleeve ring, precisely restricts the displacement of the rolling balls, avoiding the problem of increased clearance. The rotating connection design of the retaining ring and the annular groove ensures rotational freedom while limiting radial offset, improving transmission accuracy and load-bearing strength under high torque conditions, and extending bearing life.

[0018] 4. Modular Expansion and Enhanced Adaptability: The third flange provides standardized interfaces for additional modules such as sensors and brake discs, meeting intelligent requirements. The sliding fit structure between the ring guide groove and the outer ring adapts to bearing outer rings of different sizes. Specifications can be adjusted by replacing components, reducing the cost of multi-scenario modifications and enhancing application flexibility.

[0019] 5. Optimized Maintenance Convenience and Economy: The detachable design of the semi-hoop ring and clamp plate supports quick local maintenance, avoiding the cost of overall replacement. The wear-resistant properties of the rubber bushing reduce metal fatigue, and combined with the low-friction rolling path design, it significantly extends the maintenance cycle and reduces operation and maintenance costs, making it suitable for high-frequency, high-load commercial vehicle scenarios.
