Description

[Technical field]

[0001] The utility model relates to the technical field of automobile parts, in particular to a window-adjustable wheel rim. [Background Technology]

[0002] The rim is an important part of the automobile wheel system. It is located at the peripheral edge of the wheel and mainly plays the role of installing and supporting the tire. The rim is located on the outside of the vehicle and will be affected by external air resistance when the vehicle is driving, which has a certain impact on the wind resistance of the entire vehicle. It has been confirmed that the smaller the window area of ​​the rim, the smaller the wind resistance of the entire vehicle, which can reduce the energy consumption of the entire vehicle, further reduce the fuel consumption of fuel vehicles or increase the cruising range of new energy vehicles.

[0003] On the other hand, when the vehicle brakes, the friction between the brake disc and the brake caliper will generate a lot of heat. If the rim window area is smaller, it will affect the heat dissipation of the brake disc, which may further affect the braking performance and vehicle safety.

[0004] At present, the window area of ​​mass-produced rims on the market is fixed, and they can only maintain a delicate balance between reducing air resistance and not affecting the heat dissipation of the brake disc. [Contents of the utility model]

[0005] The purpose of the utility model is to solve the above-mentioned shortcomings and provide a rim with an adjustable window, whose window area is adjustable, so that the window area can be reduced to increase wind resistance when the vehicle is driving, and the window area can be increased to maintain the heat dissipation of the brake pad when the vehicle is braked and decelerated.

[0006] In order to achieve the above-mentioned purpose, a window-adjustable rim is designed, comprising a rim 1 and a plastic cover 2, wherein the rim 1 is provided with at least two rim windows 4, and the at least two rim windows 4 are evenly distributed along the circumferential direction, the plastic cover 2 is installed on the rim 1 through special fastening screws 5 and springs 3, at least two blades 100 are arranged around the plastic cover 2, and the number of the blades 100 is the same as the number of the rim windows 4, the plastic cover 2 is provided with a sliding limit groove 7, and the sliding limit groove 7 is extended and arranged along the circumferential direction, the special fastening screws 5 are arranged in the sliding limit groove 7, the plastic cover 2 rotates along the special fastening screws 5 through the sliding limit groove 7, and the blades 100 of the plastic cover 2 cover or expose the rim windows 4 as the plastic cover 2 rotates.

[0007] Furthermore, the special fastening screw 5 includes a screw mounting column 12 and a screw limiting gasket 11. The special fastening screw 5 is installed on the rim 1. The installation depth of the special fastening screw 5 is limited by the screw limiting gasket 11. The sliding limiting groove 7 on the plastic cover 2 is installed on the screw mounting column 12.

[0008] Furthermore, both sides of the sliding limit groove 7 on the plastic cover 2 are provided with limit blocks 8, and the plastic cover 2 is limited by the limit blocks 8. When the special fastening screw 5 is rotated to the limit blocks 8, the plastic cover 2 cannot rotate.

[0009] Furthermore, one side of the spring 3 is fixedly connected to a spring mounting screw 6 , and the spring mounting screw 6 is fixed to the rim 1 , and the other side of the spring 3 is connected to a spring mounting structure 9 on the plastic cover 2 .

[0010] Furthermore, the spring mounting screw 6 includes a spring mounting shaft 13 and a spring mounting screw gasket 14 , the spring 3 is fixedly connected to the spring mounting shaft 13 , and the spring mounting screw gasket 14 is screwed onto the spring mounting shaft 13 .

[0011] Furthermore, the number of the special fastening screws 5 , the sliding limit grooves 7 , the springs 3 , the spring mounting screws 6 , and the spring mounting structure 9 is the same as the number of the rim windows 4 .

[0012] Furthermore, the rim 1 is formed by die-casting of aluminum alloy, thereby ensuring that the wheel has sufficient strength, while having better appearance and improving the safety performance of the wheel.

[0013] Compared with the prior art, the utility model provides a rim with adjustable window, by adding a rotatable plastic cover on the back of a general rim, and fixing the plastic cover on the rim by fastening screws and springs, when the vehicle is running fast, under the action of centrifugal force, the plastic cover rotates, covers the rim window, reduces the window area, and thus reduces the wind resistance; when the vehicle brakes and decelerates, the speed decreases, the centrifugal force decreases, and under the action of spring tension, the plastic cover gradually rotates back and returns to the initial state, no longer covering the rim window, facilitating the heat dissipation of the brake disc, and does not affect the braking performance. In addition, the method adopted by the utility model is easy to operate, simple in structure, simple in assembly process, easy to implement, and the number of blades of the plastic cover can be adjusted as needed, and it is suitable for a variety of rims, and has high practicality.

[0014] In summary, the utility model provides a rim with adjustable window area, which reduces the window area and increases the wind resistance when the vehicle is driving, and increases the window area and maintains the heat dissipation of the brake pad when the vehicle is braking and decelerating, and is worthy of popularization and application.

[0030] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0031] The utility model mainly includes three main parts: a rim 1, a plastic cover 2 and a spring 3. In addition, the rim 1 is made of aluminum alloy castings, and the rim 1 has five rim windows 4. The number of the rim windows 4 can be adjusted as needed, such as Figure 1 As shown. Figure 2 As shown, the plastic cover 2 is composed of five blades 100, and the number of blades 100 needs to be the same as the number of rim windows 4. The plastic cover 2 is installed on the rim through special fastening screws 5 and springs 3. The special fastening screws 5 have a screw installation column 12 and a screw limit washer 11, wherein the special fastening screws 5 are first installed on the rim 1, and the screw installation depth is limited by the screw limit washer 11, leaving the screw installation column 12, and the sliding limit groove 7 on the plastic cover 2 will be installed on the screw installation column 12, as shown in FIG. Figure 6 As shown. While limiting the axial position of the plastic cover 2, the plastic cover 2 can rotate relatively along the limit groove.

Figure 4 As shown, at this time, the window area of ​​the rim is the largest and the spring is in a free installation state, as shown in Figure 7 When the vehicle is running fast, the speed increases, the rim assembly rotates quickly, and the plastic cover generates centrifugal force. When the centrifugal force is greater than the spring tension, the plastic cover 2 rotates along the rim 1, and the sliding limit groove of the plastic cover 2 rotates along the special fastening screw 5. The higher the speed, the greater the rotation angle, until the limit block 8 hits the special fastening screw 5, and the plastic cover 2 can no longer rotate. At this time, the plastic cover 2 is fully opened, as shown in FIG. Fig.10 , just completely covers the rim window 4, such as Fig.11 shown.
