Description

Technical Field

[0001] This utility model relates to the field of display technology, and more specifically, to a closed wheel hub assembly. Background Technology

[0002] Wheel hubs are a particularly important component in the automotive industry. Through our research, we have created this new type of wheel hub, which is mainly designed to meet the needs of vehicle protection, aesthetics, and certain special operating conditions.

[0003] Existing wheel hub cooling designs mostly rely on simple air inlets or external heat sinks, resulting in low cooling efficiency, poor airflow guidance, and complex structures. Furthermore, the connection between the wheel hub and the center cover is often rigidly fixed, lacking cushioning and sealing design, which can easily lead to component loosening or rainwater infiltration.

[0004] In some engineering vehicles or specific industrial equipment, enclosed wheel assemblies can prevent dust, mud, and other contaminants from entering the wheel hub, protecting components such as wheel bearings. However, traditional wheel assemblies are prone to overheating during vehicle operation due to heat buildup from brake pads, affecting braking performance and wheel life.

[0005] Therefore, it is necessary to propose a closed-loop hub assembly to solve the aforementioned technical problems. Utility Model Content

[0006] This utility model provides a closed wheel hub assembly, which solves the technical problems of poor heat dissipation and easy corrosion of existing wheel hubs by optimizing airflow guidance, strengthening heat dissipation structure and integrated connection design.

[0007] According to one aspect of the present invention, a closed wheel hub assembly is provided, including a wheel hub, a center cover, and brake pads. One end of the wheel hub is concave inward in a lotus leaf shape to form an arc-shaped end cap. The end cap includes a guide portion disposed on the outer edge and a guide portion disposed on the inner edge. The guide portion is provided with vent holes. The edge of the center cover abuts against the connection between the guide portion and the guide portion and is locked to the guide portion by bolts. The outer edge surface of the center cover is provided with air inlets spaced apart in a fish fin shape. The brake pads are disposed on the side of the guide portion opposite to the center cover.

[0008] Based on the above scheme, a stepped surface is formed between the guide part and the flow guide part, and the outer edge of the central cover abuts against the stepped surface.

[0009] Based on the above scheme, preferably, the surface of the guide section is provided with multiple arc-shaped guide grooves in the shape of vortex.

[0010] Based on the above scheme, preferably, the central cover includes a covering part and a drainage part. The edge of the covering part is inclined downward to form a conical circular surface, and a drainage groove is provided on the conical circular surface. A fin-shaped heat dissipation plate is provided on the drainage part, and the heat dissipation plate is spaced apart to form the air inlet hole.

[0011] Based on the above scheme, preferably, the heat sink is composed of multiple evenly spaced components arranged at the edge of the conical circular surface, the heat sink is spiral in shape as a whole, and the heat sink is arranged at an angle.

[0012] Preferably, based on the above scheme, the bolt is installed between the cover and the hub for fixation.

[0013] Preferably, based on the above scheme, a decorative cover is provided on the outer side of the wheel hub.

[0014] This utility model discloses a closed wheel hub assembly. It adopts a closed design with a vent hole only below the arc-shaped end cap and a central cover above the vent hole. This can effectively prevent dust, mud and other dirt from entering the brake disc behind the wheel hub. In addition, an arc-shaped guide groove is made on the arc-shaped end cap to provide air ducts. This can satisfy the wheel hub to have a good effect of blocking mud and sand, and at the same time, it can also provide heat dissipation for the brake disc. Attached Figure Description

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0033] Please see Figure 1 and combined Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a closed wheel hub assembly, which includes a wheel hub 1, a center cover 2, and brake pads 3.

[0034] One end face of the hub 1 is concave inward in a lotus leaf shape to form an arc-shaped end cap 11. The end cap 11 includes a guide portion 12 disposed on the outer ring and a guide portion 14 disposed at the center. The guide portion 12 is used to guide the external airflow along the surface of the hub 1, and the guide portion 14 further optimizes the airflow path through a vortex-shaped arc-shaped guide groove 13.

[0035] The edge of the central cover 2 presses against the connection between the guide part 14 and the flow guide part 12, and is locked to the guide part 14 by bolts. The surface of the central cover 2 is provided with vent holes 15, and the outer edge is provided with fin-shaped air inlets 25, forming a multi-stage airflow channel.

[0036] Brake pad 3: It is located on the side of the guide part 14 away from the center cover 2, and heat dissipation is achieved through the integrated design of the guide part 14 and the wheel hub 1.

[0037] The wheel hub 1 is mounted on the wheel axle, and the center cover 2 is mounted on the wheel hub 1. During vehicle operation, the design of the center cover 2 slightly blocks external mud and sand from entering the wheel hub 1. Simultaneously, the design of the air guide 12 creates a vortex that quickly directs air into the fin-shaped air intake, effectively filtering out some mud and sand. The air entering the air intake then quickly passes through the vent 15 and acts on the brake disc, rapidly cooling it and providing continuous airflow for heat dissipation.

[0038] It is worth noting that in this invention, a stepped surface 16 is formed between the guide part 14 and the flow guide part 12, and the outer edge of the center cover 2 abuts against the stepped surface 16, which enhances the connection sealing and disperses mechanical stress.

[0039] Please continue reading. Figure 3 As shown, this utility model provides multiple vortex-shaped arc-shaped guide grooves 13 on the surface of the guide part 14 to guide the airflow along the spiral path, reduce turbulence and improve heat dissipation efficiency.

[0040] Furthermore, the central cover 2 of this utility model adopts a layered design, that is, the central cover 2 includes a covering part 21 and a drainage part 24. The covering part 21 has a downwardly curved edge to form a conical circular surface 22, and a drainage groove 23 is provided on the surface to accelerate the airflow discharge. The drainage part 24 has a spiral inclined heat dissipation plate 26, and the air inlet holes 25 are formed at even intervals. The spiral structure prolongs the airflow residence time and enhances the heat dissipation effect.

[0041] Furthermore, the outer side of the wheel hub 1 of this utility model is provided with a decorative cover 4, which has both aesthetic and dustproof functions, and a buffer pad is installed between the wheel hub 1 and the center cover 2 to reduce vibration and impact and improve sealing.

[0042] Compared with the prior art, the present invention has the following advantages:

[0043] First, the guide section 12 guides the external airflow into the hub 1, and the guide groove 13 further forms a vortex to accelerate heat exchange. The airflow path is extended by the spiral inclined heat dissipation plate 26, and the air inlet 25 formed by the fish fin heat dissipation plate 26 forms a heat dissipation channel, which improves the heat dissipation efficiency by more than 30%.

[0044] A stepped surface 16 is formed between the guide part 14 and the flow guide part 12 to position the center cover 2. The bolt fixing combined with the buffer pad design reduces the risk of loosening and improves the shock resistance.

[0045] The conical circular surface 22 is designed to prevent rainwater from seeping in directly, and the drainage channel 23 quickly drains accumulated water to avoid corrosion of internal components.

[0046] Brake pad 3 works in tandem with heat dissipation: the heat from brake pad 3 is quickly conducted to the surface of wheel hub 1 through guide part 14, and combined with airflow heat dissipation, the temperature rise of brake pad 3 is reduced by 20%-25%, and the life of braking system is extended.

[0047] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
