Service HotlineIn automobiles, wheel nuts are a widely used component. According to the actual use requirements of the wheel nut, there are often spacers on the wheel nut. In this way, the wheel nut and spacer form a wheel nut assembly. However, in the prior art, since the washer is only movably fitted on the wheel nut, when the wheel nut is removed or a large number of wheel nuts are placed, the wheel nut and the washer will be separated. When in use, they need to be assembled one by one, and when they are disassembled or placed again after use, they need to be assembled again, which not only increases the unnecessary workload, but also affects the use effect of the wheel nut in actual use.

The defect of the existing press-fit solution is: when the retaining ring is placed in the chamfering section or the guide section of the shaft head, the retaining ring cannot be accurately fixed, and the retaining ring is easy to tilt or fall, especially when the shaft head is located inside the bearing chamber depression, The inclination of the retaining ring will make it difficult to press the retaining ring, affect the production efficiency, and even cause the product to be scrapped.
The core rivet is a new type of riveting fastener that is very convenient for riveting. It can show its unique advantages in a relatively small space or in an environment where there is no rivet gun or a rivet gun cannot be used. Two or more connected parts can be riveted successfully by hitting the mandrel on one side with a hammer or other utensils. Core rivets can be divided into oblate head core rivets and countersunk head core rivets according to the shape of the brim of the nail cap. According to different material combinations, they can be divided into all aluminum core rivets, aluminum steel core rivets, and all stainless steel core rivets. Rivets, steel rivets, aluminum stainless steel rivets, plastic rivets, etc. Core rivets do not have to be riveted with manual riveting guns or pneumatic riveting guns like blind rivets. They have better riveting and convenience, and can be widely used in the riveting of various connected parts.
