Detailed Description
In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined below to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.
At present, the rim of the automobile is generally integrated, and the width of the rim is fixed and cannot be adjusted. When rims with different widths need to be adopted, a new rim needs to be developed again, rims with various widths coexist simultaneously, and a mold needs to be developed again for each rim with different widths, so that the production cost is increased; in addition, when a crack occurs on one side of the rim, the entire rim needs to be replaced because the rim is of a unitary structure, thereby resulting in high maintenance costs. Therefore, in order to reduce the development cost and the use cost and improve the product generalization and the product quality, a new automobile rim needs to be developed urgently.
Accordingly, embodiments of the present invention provide a variable width automotive rim, as shown in fig. 1-3, which may include: a left rim body 1 and a right rim body 2. Specifically, one end of the left rim body 1 is provided with an internal thread 11, one end of the right rim body 2 is provided with an external thread 21 matched with the internal thread 11, and the left rim body 1 and the right rim body 2 are in threaded connection through the internal thread 11 and the external thread 21. Of course, in practical application, an external thread may be provided on the left rim body 1, and an internal thread matched with the external thread may be provided on the right rim body 2. Through dividing into left rim body 1 and right rim body 2 two with the automobile rim, and pass through threaded connection between the two, it is adjustable to have realized the automobile rim width in the certain limit, and adjust convenient and fast, can obtain accurate automobile rim width, development manufacturing cost has been reduced from this, in addition, when fracture or defect appear in automobile rim one side, only need to change the rim of defect one side can (left rim body or right rim body 2), need not all to change whole automobile rim, thereby effectively reduced automobile rim's maintenance cost.
That is to say, in the embodiment of the utility model, through the volume of adjusting the dose of threaded connection part length, can obtain the automobile rim of different widths for switching between the rim of different widths is more convenient, can satisfy the different width rim requirements of front and back wheel even, also promptly: for the driving wheel, the rim width is increased, the contact area between the tire and the ground is enlarged, and the friction force between the tire and the ground is increased, so that the driving force of the whole vehicle is ensured; for the driven steering wheel, the rim width can be reduced, the steering is flexible and light, and the stability of the whole vehicle is ensured while the better driving force of the whole vehicle is met by adjusting different rim widths.
In the embodiment of the present invention, the automobile rim may further include a sealing device, the sealing device is disposed at a connection position of the internal thread 11 of the left rim body 1 and the external thread 21 of the right rim body 2, so as to ensure the sealing performance between the left rim body 1 and the right rim body 2. Specifically, the sealing device can include a sealant coated on the internal thread 11 and/or the external thread 21, and the sealant is coated on the connecting portion to fill the gap between the threads, so that the sealing performance between the threads can be effectively improved, the tire inflation leakage can be prevented, the connection firmness between the left rim body 1 and the right rim body 2 can be improved by the sealant, and the structural strength of the automobile rim formed by the left rim body and the right rim body can be improved.
In other embodiments of the present invention, as shown in fig. 3 and 4, the sealing device may further include a sealing ring 3 disposed in the groove of the internal thread 11 and/or the external thread 21. Specifically, the seal ring 3 may be provided in a thread groove of the female thread 11 or in a thread groove of the male thread 21, and after the left rim body 1 and the right rim body 2 are screwed together, the seal end 3 may further seal the screwed joint, and the seal ring 3 may be brought into close contact with the left rim body 1 and/or the right rim body 2 under the tire inflation pressure, thereby enhancing the sealing performance of the screwed joint. It can be known that, when the tire pressure is bigger, the pressure borne by the sealing ring 3 will also increase, so as to be closer to the left rim body 1 and/or the right rim body 2, and the sealing effect is better.
In some embodiments of the present invention, the cross-sectional shape of the sealing ring 3 is adapted to the shape of the thread groove, so that the sealing ring 3 can better fill and seal the threaded connection portion between the left rim body 1 and the right rim body 2, and ensure the sealing performance. Preferably, as shown in fig. 5, the cross-sectional shape of the sealing ring 3 may be a parallelogram, which is closer to the actual cross-sectional shape of the thread groove, so as to have a better sealing effect. In particular implementation the utility model discloses the time, the quantity of sealing washer 3 can suitably increase, and its position also can rationally lay in screw thread length direction to obtain better sealed effect.
In other embodiments of the present invention, a left rim connected to the left bead opening of the tire is disposed at an end of the left rim body 1 away from the internal thread 11, and a right rim connected to the right bead opening of the tire is disposed at an end of the right rim body 2 away from the external thread 21, so as to fix the left rim body to the tire; by adjusting the screwing depth of the threads, automobile rims with different widths can be obtained, so that tires with different widths can be matched.
According to the utility model discloses but width-changing's automobile rim, through fall into left rim body 1 and right rim body 2 two parts with automobile rim, and pass through threaded connection between the two, it is adjustable to have realized the automobile rim width in the certain limit, and adjust convenient and fast, can obtain accurate automobile rim width, development manufacturing cost has been reduced from this, in addition, when crack or defect appear in automobile rim one side, only need to change the rim of defect one side can (left side rim body or right rim body 2), need not all to change whole automobile rim, thereby effectively reduced automobile rim's maintenance cost.
The utility model discloses another aspect embodiment still provides a vehicle, the vehicle includes as above arbitrary embodiment the automobile rim of variable width, because the automobile rim in above-mentioned embodiment has foretell beneficial effect, the utility model discloses the vehicle in the embodiment also has corresponding technological effect, no longer gives details here.
