Description

Technical Field

[0001] This utility model belongs to the field of sealing ring technology and relates to a static waterproof and dustproof sealing ring. Background Technology

[0002] In current wheel hub unit manufacturing processes, the connection of the mandrel is typically achieved using a riveting process. However, this riveting process often leads to deformation of the inner ring dimensions during operation, which is detrimental to maintaining the wheel hub's precision and performance. Furthermore, the riveting process is technically challenging, making it difficult to ensure an ideal seal between the wheel hub mandrel and the inner ring. This can allow contaminants such as water and dust to infiltrate, affecting the wheel hub's lifespan and reliability. Given these issues, designing a static waterproof and dustproof sealing ring becomes crucial. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a static waterproof and dustproof sealing ring.

[0004] To achieve the above objectives, the technical solution of this utility model is: a static waterproof and dustproof sealing ring, comprising a skeleton, wherein the skeleton has a rubber body, characterized in that the cross-section of the skeleton is Z-shaped, and the rubber body has an inner ring sealing lip and a spindle sealing lip, wherein the lip of the inner ring sealing lip contacts the inner ring of the hub unit, and the lip of the spindle sealing lip contacts the hub spindle.

[0005] The inner ring sealing lip is arranged obliquely outward, and the mandrel sealing lip is arranged obliquely inward.

[0006] The inner ring sealing lip is located at one end of the skeleton, and the mandrel sealing lip is located at the other end of the skeleton.

[0007] The mandrel sealing lip has a reinforcing colloid between its root and the other end of the skeleton.

[0008] The inner surface of one end of the frame and the inner surface of the middle section of the frame are in contact with the inner ring of the wheel hub unit.

[0009] By adopting the above technical solution, the beneficial effects of this utility model are:

[0010] The waterproof and dustproof sealing ring in this invention can replace the riveting process and can effectively prevent the intrusion of dust and mud from the outside. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model.

[0012] In the figure, 1a is the skeleton; 1b is the rubber body; 1c is the inner ring sealing lip; 1d is the spindle sealing lip; 1e is the outer ring of the hub unit; 1f is the hub oil seal; 1g is the inner ring of the hub unit; 1h is the hub spindle; and 1i is the reinforcing colloid. Detailed Implementation

[0013] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0014] like Figure 1 As shown, this static waterproof and dustproof sealing ring includes a skeleton 1a, a rubber body 1b on the skeleton 1a, the cross-section of the skeleton 1a is Z-shaped, and the rubber body 1b has an inner ring sealing lip 1c and a spindle sealing lip 1d. The lip of the inner ring sealing lip 1c contacts the inner ring 1g of the hub unit, and the inner ring sealing lip 1c provides a static seal to prevent mud and water from entering the hub spindle 1h through the inner ring 1g of the hub unit. The lip of the spindle sealing lip 1d contacts the hub spindle 1h, and the spindle sealing lip 1d provides a static seal to prevent mud and water from entering the hub spindle 1h. The inner ring sealing lip 1c is arranged inclined outwards, and the spindle sealing lip 1d is arranged inclined inwards.

[0015] The inner ring sealing lip 1c is located at one end of the skeleton 1a, and the mandrel sealing lip 1d is located at the other end of the skeleton 1a; a reinforcing colloid 1i is also provided between the root of the mandrel sealing lip 1d and the other end of the skeleton 1a.

[0016] The inner side of one end of the frame 1a and the inner side of the middle section of the frame 1a are in contact with the inner ring 1g of the hub unit.

[0017] In summary, by adopting a static sealing structure, external dust and mud can be effectively prevented from entering the spindle, thereby avoiding hub unit failure due to rust.

[0018] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0019] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
