Description

Technical Field

[0001] This utility model relates to the field of automotive wheel hub technology, specifically to an automotive wheel hub with adjustable heat dissipation performance. Background Technology

[0002] Adjustable heat dissipation automotive wheel hubs are a type of wheel hub cooling system that can dynamically adjust heat dissipation efficiency according to driving conditions (such as temperature, vehicle speed, and brake load) to balance air resistance, brake cooling, and energy consumption.

[0003] The adjustable heat dissipation performance of a car wheel hub disclosed in CN220031610U has the following advantages: when in use, the air intake slope can drive the air in the car while it is in motion and blow it into the inside of the car wheel hub, so that the airflow fills the entire inside of the wheel hub and then overflows from the edge of the wheel hub, which cools down the wheel hub and brake disc; moreover, it has an aesthetically pleasing design and high support strength.

[0004] However, this adjustable heat dissipation car wheel hub has the following disadvantages: it is not convenient to adjust the heat dissipation performance of the car wheel hub according to the heat of the car wheel hub; it is not convenient to strengthen the frame of the wheel hub to improve the heat dissipation efficiency. Utility Model Content

[0005] The technical problems to be solved by this utility model are as follows: it is not convenient to adjust the heat dissipation performance of the car wheel hub according to the heat of the car wheel hub; it is not convenient to strengthen the frame of the wheel hub and improve the heat dissipation efficiency at the same time.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An adjustable heat dissipation automotive wheel hub includes a wheel hub body, a wheel hub slab disposed inside the wheel hub body, a retaining ring fixedly connected to the inner side of the wheel hub slab, a centrifugal exhaust assembly fixedly connected to one side of the retaining ring, a thermal resistance assembly disposed on the surface of the retaining ring, and finned strips disposed on the inner side of the wheel hub body. The centrifugal exhaust assembly includes a bearing, a fan ring, and fan blades; the thermal resistance assembly includes a fixed cylinder, a shape memory alloy spring, a telescopic column, and a pressure ball.

[0008] As a further embodiment of this utility model: the wheel hub body includes an inner ring and a limiting outer ring, and there are two limiting outer rings, which are symmetrically distributed on both sides of the inner ring. The slots facilitate the later installation of the wheel hub on the vehicle.

[0009] As a further embodiment of this utility model: three slots are provided in the middle of the surface of the wheel hub piece, and six exhaust holes are provided on the outer side of the surface of the wheel hub piece. The slots facilitate the later installation of the wheel hub on the vehicle.

[0010] As a further embodiment of this utility model: one end of the bearing is fixedly installed on one end of the receiving ring, and a fan ring is fixedly connected to the outside of the bearing. A fan blade is provided on the outside of the fan ring. Through the arrangement of the bearing, it plays a role in cooperating with the thermal resistance component to perform heat adaptive exhaust.

[0011] As a further aspect of this utility model: the number of fan blades is several, and the several fan blades are evenly distributed in a circular matrix on the outer side of the fan ring. The evenly arranged fan blades improve the heat dissipation efficiency inside the tire.

[0012] As a further embodiment of this utility model: the bottom of the fixed cylinder is fixedly connected to the surface of the receiving ring, a memory alloy spring is provided on the inner bottom wall of the fixed cylinder, a telescopic column is fixedly connected to the top of the memory alloy spring, and a pressure ball is fixedly connected to the top of the telescopic column. By setting the memory alloy spring, the heat dissipation efficiency of the wheel hub is adaptively adjusted as the temperature rises.

[0013] As a further embodiment of this utility model: the surface of the telescopic column is slidably connected to the inside of the fixed cylinder, and the pressure ball is assembled such that when the memory alloy spring is heated and expands, it drives the telescopic column and the pressure ball to press against the inner side of the fan ring. The fixed cylinder is designed to ensure that the telescopic column can slide in a limited position.

[0014] The beneficial effects of this utility model are:

[0015] 1. Through the integrated design of centrifugal exhaust components and thermal resistance components, when the heat inside the wheel hub body rises, the heat is transferred from the fixed cylinder to the internal shape memory alloy spring. Due to its metallic properties, the shape memory alloy spring expands when heated, promoting the upward sliding of the telescopic column and simultaneously driving the pressure ball to press against the inner side of the fan ring. Therefore, the higher the internal heat of the wheel hub body, the stronger the pressure of the pressure ball against the fan ring, and the stronger the resistance to the rotation of the bearing. As the tire rotates, the centrifugal wind force generated by the fan blades is greater, and the efficiency of the hot air discharged outward is higher. Thus, the car wheel hub can self-adjust its heat dissipation performance as the temperature rises.

[0016] 2. By setting fin strips, the inner side of the wheel hub body is provided with fin strips with a ring mesh structure, which increases the heat dissipation area on the surface of the wheel hub. At the same time, the frame structure formed by the fin strips improves the overall strength of the car wheel hub. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, an adjustable heat dissipation automotive wheel hub includes a wheel hub body 1, a wheel hub plate 2 inside the wheel hub body 1, a receiving ring 3 fixedly connected to the inner side of the wheel hub plate 2, a centrifugal exhaust assembly 4 fixedly connected to one side of the receiving ring 3, and a thermal resistance assembly 5 on the surface of the receiving ring 3. Through the combined arrangement of the centrifugal exhaust assembly 4 and the thermal resistance assembly 5, when the internal heat of the wheel hub body 1 rises, the heat is transferred from the fixed cylinder 501 to the internal shape memory alloy spring 502. Due to its metallic properties, the shape memory alloy spring 502 expands when heated, promoting the upward sliding of the telescopic column 503 and simultaneously driving the pressure ball 504 to press against the inner side of the fan ring 402. Therefore, as the internal heat of the wheel hub body 1 increases, the pressure ball 504 presses against the inner side of the fan ring 402. The stronger the pressure of the pressure ball 504 against the fan ring 402, the stronger the resistance to the rotation of the bearing 401. As the tire rotates, the centrifugal wind force generated by the fan blade 403 is greater, enabling the car wheel hub to self-adjust its heat dissipation performance as the temperature rises. The inner side of the wheel hub body 1 is provided with fin strips 6. Through the setting of fin strips 6, the inner side of the wheel hub body 1 is provided with fin strips 6 of a ring mesh structure, which increases the heat dissipation area on the surface of the wheel hub. At the same time, the frame structure formed by the fin strips 6 improves the overall strength of the car wheel hub. The centrifugal exhaust assembly 4 includes a bearing 401, a fan ring 402 and a fan blade 403. The thermal resistance assembly 5 includes a fixed cylinder 501, a memory alloy spring 502, a telescopic column 503 and a pressure ball 504.

[0025] like Figure 4 As shown, the wheel hub body 1 includes an inner ring 101 and a limiting outer ring 102. There are two limiting outer rings 102, which are symmetrically distributed on both sides of the inner ring 101. The limiting outer rings 102 facilitate the installation of rubber tires and limit their movement.

[0026] like Figure 1 As shown, three slots are provided in the center of the surface of the wheel hub piece 2, and six exhaust holes are provided on the outer side of the surface of the wheel hub piece 2. The slots facilitate the later installation of the wheel hub on the vehicle.

[0027] like Figure 2 As shown, one end of the bearing 401 is fixedly installed on one end of the receiving ring 3. A fan ring 402 is fixedly connected to the outside of the bearing 401. A fan blade 403 is provided on the outside of the fan ring 402. The bearing 401 plays a role in cooperating with the thermal resistance component 5 to perform heat adaptive exhaust.

[0028] like Figure 2 As shown, there are several fan blades 403, which are evenly distributed in a circular matrix on the outer side of the fan ring 402. The evenly arranged fan blades 403 improve the heat dissipation efficiency inside the tire.

[0029] like Figure 3 As shown, the bottom of the fixed cylinder 501 is fixedly connected to the surface of the receiving ring 3. A memory alloy spring 502 is provided on the inner bottom wall of the fixed cylinder 501. A telescopic column 503 is fixedly connected to the top of the memory alloy spring 502. A pressure ball 504 is fixedly connected to the top of the telescopic column 503. The setting of the memory alloy spring 502 promotes the effect of adaptive adjustment of heat dissipation efficiency of the wheel hub as the temperature rises.

[0030] like Figure 2 As shown, the surface of the telescopic column 503 is slidably connected to the inside of the fixed cylinder 501, and the pressure ball 504 is assembled so that when the shape memory alloy spring 502 is heated and expands, it drives the telescopic column 503 and the pressure ball 504 to press against the inner side of the fan ring 402. The fixed cylinder 501 is designed to ensure that the telescopic column 503 can slide in a limited position.

[0031] The working principle of this utility model is as follows: When the heat inside the wheel hub body 1 rises, the heat is transferred from the fixed cylinder 501 to the internal shape memory alloy spring 502. Then, due to its metallic properties, the shape memory alloy spring 502 expands when heated, promoting the upward sliding of the telescopic column 503 and simultaneously driving the pressure ball 504 to press against the inner side of the fan ring 402. Therefore, as the heat inside the wheel hub body 1 increases, the pressure of the pressure ball 504 against the fan ring 402 becomes stronger, and the resistance to the rotation of the bearing 401 becomes stronger. As the tire rotates, the centrifugal wind force generated by the fan blade 403 becomes greater, and the efficiency of the hot air discharged outward is higher.

[0032] The inner side of the hub body 1 is provided with fin strips 6 with a ring mesh structure, which increases the heat dissipation area on the surface of the hub, and the fin strips 6 form a frame structure.

[0033] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
