Description

Technical Field

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

[0002] The ABS sensor senses the wheel speed by sensing the Hall signal of the target wheel. When the speed is lower than the set value, the ABS stops working. You don't need to brake hard on icy and snowy roads. The brake switch makes the ABS work, and the ABS sensor is used to detect whether the wheel is locked and the speed. In heavy-duty vehicles, in order to improve braking efficiency and reduce braking failures, ABS automatic clearance adjustment arms are standard for the whole vehicle. At present, the ABS gear ring and the wheel hub are interference fit on heavy-duty axles. The ABS gear ring is pressed on the wheel hub. During operation, the ABS gear ring will be heated, which can easily cause the ABS gear ring to deform. In addition, the assembly of the ABS gear ring is also very strict. The tooth surface of the ABS gear ring must be flat after assembly. There are requirements for the runout of the ABS gear ring disk, which needs to be inspected after assembly. However, when the gear ring and the wheel hub are heated differently, the interference fit can easily cause the ABS gear ring to loosen, resulting in unstable ABS transmission signals and brake failures.

[0003] Patent No. CN202321894045.9 discloses a device including a flange, the center of which is fixedly connected to a bearing sleeve. A gear ring is integrally formed on the outer wall of one end of the bearing sleeve, and a plurality of tooth groups are evenly arranged around the outer wall of the gear ring, and each of the tooth groups includes a plurality of teeth distributed at equal intervals. A wide tooth is arranged between each two adjacent tooth groups, and the distance between the wide tooth and the tooth is the same as the distance between two adjacent teeth, and the axial width of the wide tooth is greater than the axial width of the tooth. The utility model is provided with an integrally formed structure of the gear ring and the bearing sleeve, and the gear ring and the bearing sleeve are heated together during the working process, so that the gear ring is not easy to be axially offset and circumferentially rotated relative to the bearing sleeve, thereby solving the problem of structural instability caused by the secondary assembly of the gear ring, improving the stability of ABS signal transmission, and reducing braking failures. When the gear ring is exposed to the outside, stones and larger particles of impurities fall into it, which will cause collision and wear of the tooth surface of the gear ring, thus causing ABS failure. Therefore, the utility model proposes a wheel hub with an ABS gear ring. Utility Model Content
