[0002] The wheel hub bearing unit is the part where the axle is installed in the center of the wheel. It is mainly used to connect the brake drum, wheel disc and half shaft, and is mounted on the axle tube or steering knuckle journal through the bearing.

[0003] With the advancement of technology, most of the current automobile wheel hub units are forged and formed at one time during the processing process, which reduces the cumbersome cutting process. There are also many types of automobile wheel hub units with less cutting. For example, Chinese patent CN219994186U discloses a lightweight wheel hub bearing unit for a small car, including a dust cover and other structures. The hub unit can effectively perform dust prevention treatment, but the automobile wheel hub units with less cutting on the existing market still have the defect of easily causing surface damage. Because traditional automobile wheel hub units lack protective treatment for outer components, they are easily affected by external influences during use and have defects such as scratches or scrapes, which will affect the service life of the automobile wheel hub unit over time. Therefore, a automobile wheel hub unit with less cutting is proposed to solve the above problem. Utility Model Content

[0020] 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.

[0021] See also Figure 1-2The utility model provides the following technical solution: a low-chip automobile wheel hub unit, comprising a bearing outer ring 1, a flange body 2 integrally formed on the circumferential surface of the bearing outer ring 1, a plurality of bolts 3 extending to the bottom of the flange body 2 are threadedly connected to the top of the flange body 2, the number of the bolts 3 is three, and the three bolts 3 are equidistantly distributed around the center of the bearing outer ring 1 as a symmetrical point.

[0022] Among them, a plurality of clamping seats 4 are provided on the top of the flange body 2, a clamping groove is opened on the top of the clamping seat 4, and the clamping groove is adapted to the clamping block 9. A rubber sleeve 5 is tightly fitted on the bottom of the flange body 2, and three sleeve holes are opened on the bottom of the rubber sleeve 5, and the sleeve holes are adapted to the bolts 3. The inner side of the rubber sleeve 5 is sleeved with the bolts 3, and a protective sleeve 6 is sleeved on the outer side of the flange body 2. The protective sleeve 6 is a flexible sponge protective sleeve, and the shape of the protective sleeve is a circular ring. A plurality of connecting members 7 are fixedly connected to the outer side of the protective sleeve 6. The number of the connecting members 7 is six, and the six connecting members 7 are equidistantly distributed on the outer side of the protective sleeve 6. A fixing plate 8 is fixedly connected to the inner side of the connecting member 7, and a clamping block 9 is fixedly connected to the bottom of the fixing plate 8, and the bottom of the clamping block 9 is clamped with the clamping seat 4.
