Description

Technical Field

[0001] The utility model relates to the field of automobile wheel hubs, in particular to a wheel hub bearing assembly with an ABS gear ring. Background Art

[0002] ABS (Anti-lock Braking System) has been widely used in the automotive field. Its functions are: 1) give full play to the effectiveness of the brakes and shorten the braking time and distance; 2) effectively prevent the vehicle from skidding and tail-swinging during emergency braking, and have good driving stability; 3) can turn during emergency braking, and have good steering maneuverability; 4) can avoid severe friction between the tire and the ground and reduce tire wear. The sensor installed on the wheel sends a signal that the wheel will be locked, which can improve the safety factor of emergency braking of the vehicle during driving. The existing wheel hub bearing assembly for light commercial vehicles uses double-row tapered roller bearings. When running under very complex road conditions, the ABS gear ring is easy to slip and fall off, causing the ABS sensor probe to wear or break and unable to collect data, and finally causing the ABS system to fail. When the car encounters an emergency, emergency braking will cause the tire to lock, that is, the steering wheel cannot turn, so the risk factor will increase accordingly, which is easy to cause serious consequences. In addition, the traditional ABS gear ring structure will increase the product usage space and increase the product material weight. Utility Model Content

[0003] Aiming at the deficiencies of the prior art, the invention mainly solves the problem of slipping and easy falling of the ABS gear ring in the prior products, and at the same time solves the problem of large material loss and high cost. The utility model provides a wheel hub bearing assembly with an ABS gear ring, wherein the ABS gear ring is fastened to the mandrel, thereby improving the safety factor of emergency braking of the vehicle when the vehicle is driving, reducing the weight of the product and reducing the cost.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a wheel hub bearing assembly with an ABS gear ring, comprising an outer ring, an inner ring, a core shaft, an ABS gear ring, a retaining frame, rollers and a sealing assembly, wherein the ABS gear ring is pressed onto the core shaft, a threaded hole is provided in the middle of the core shaft, and the ABS gear ring is fastened to the core shaft by screws.

[0005] Preferably, the sealing assembly includes a seal A and a seal B.

[0006] As a preferred embodiment, the outer ring is provided with hub bolts for connecting the wheel.

[0007] The beneficial effects of the utility model are as follows: by machining a threaded hole in the center of the wheel hub shaft, the ABS gear ring is directly fixed on the spindle with screws, so that the ABS gear ring is firmly locked on the wheel hub shaft. The safety factor of emergency braking of the vehicle is improved when the vehicle is driving. The overall structure is compact, the installation is convenient, the performance is excellent, the product weight is reduced, and the cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] A hub bearing assembly with an ABS gear ring includes an outer ring 1, an inner ring 2, a spindle 3, an ABS gear ring 4, a retainer 7, a roller 8 and a sealing assembly, wherein the sealing assembly includes a seal A6 and a seal B9. The ABS gear ring 4 is press-fitted onto the spindle 3, a threaded hole 11 is provided in the middle of the spindle 3, and the ABS gear ring 4 is fastened to the spindle 3 by screws 5. The outer ring 1 is provided with a hub bolt 10 for connecting the wheel. The thread specifications of the threaded hole 11 and the screw 5 are M14x1.5.

[0015] In the utility model, the outer ring 1 is machined with two raceways on the part, and is used as the base for the roller to carry and rotate through local induction hardening, grinding and super finishing. The inner ring 2, the outer ring 1 and the roller 8 are combined into a load-bearing and rotating component. The mandrel 3 is combined with the inner ring 2, the outer ring 1 and the roller 8 through the shaft diameter to form a complete load-bearing and rotating component, and is fixed by the interference fit between the outer diameter and the inner diameter of the mandrel 3. The ABS gear ring 4 is pressed onto the mandrel 3, and the wheel speed sensor outputs a signal by acting on the gear ring that rotates synchronously with the wheel. The screw 5 fixes the ABS gear ring 4 on the mandrel 3. The seal A6 is pressed between the inner ring 2 and the outer ring 1 to achieve a sealing effect. The retaining frame 7 guides the roller 8 to rotate. The roller 8 carries and transmits. The sealing ring B9 cooperates with the outer ring 1 to achieve a sealing effect. The wheel hub bolt 10 connects the wheel.

[0016] This structural function has been verified through many tests and can completely avoid the phenomenon of gear ring slipping or falling off, and it fully meets the requirements in use. The overall optimized design greatly improves the service life of the bearing. The utility model has the characteristics of low cost, compact structure, easy installation, and superior performance.

[0017] During installation, press the 6 bolts 10 into the core shaft 3 with a hydraulic press, first evenly load the 22 rollers 8 into the retainer 7, then install the row of retainers 7 onto the raceway of the core shaft 3, then evenly load another 22 rollers 8 into the retainer 7, then install the row of retainers 7 onto the raceway of the inner ring 2, then press the sealing ring B9 onto the outer ring 1 with a hydraulic press, evenly grease the raceways on both sides of the outer ring, then install the outer ring 1 onto the core shaft 3, then press the inner ring 2 onto the axial diameter of the core shaft 3, curl the end of the core shaft 3 with a flanging machine, and then press the sealing ring assembly A6, finally tighten the ABS gear ring 4 onto the core shaft 3 with screws 5, at this point, the product installation is complete.
