DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described and illustrated in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments provided by the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0034] Obviously, the drawings described below are only some examples or embodiments of the utility model. For ordinary technicians in this field, the utility model can also be applied to other similar scenarios based on these drawings without creative work. In addition, it can be understood that although the efforts made in this development process may be complicated and lengthy, for ordinary technicians in this field related to the content disclosed by the utility model, some changes in design, manufacturing or production based on the technical content disclosed by the utility model are just conventional technical means, and should not be understood as the content disclosed by the utility model is insufficient.

[0035] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments without conflict.

[0036] A flexible low-wear lateral stop mechanism comprises a first hinge and a second hinge which are hingedly connected via a hinge pin; wherein the first hinge 1 and / or the second hinge 2 are made of a flexible material; in other words, at least one of the first hinge 1 and the second hinge 2 is made of a flexible material or both are made of a flexible material, so as to overcome the lateral offset force generated between the inner and outer wheel rims of a car during driving by using the elastic deformation force of the flexible material itself, thereby reducing the impact force and the amount of wear. At the same time, considering that the above-mentioned components are frequently subjected to stress, a single lubrication channel cannot provide a good lubrication effect, and the following improvements are made to their structure, including: a first bushing 9 and a second bushing 10, the first bushing 9 and the second bushing 10 are respectively arranged between the first hinge 1 and the hinge pin 3 and between the second hinge 2 and the hinge pin 3; the bushing is a connected shaft kit, which is a conventional replacement part that is easy to wear. In order to extend its service life, a first oil filling port 4 and a second oil filling port 5 are opened, wherein the first oil filling port 4 is opened at one side end of the hinge pin 3, and is communicated with the inner oil groove 6 opened on the outer wall of the hinge pin 3 through the inner oil guide channel 7; the second oil filling port 5 is opened on the first hinge 1, and is communicated with the outer oil groove 16 opened on the outer wall of the first bushing 9 through the outer oil guide channel 8.

[0037] The inner oil groove 6 and the outer oil groove 16 are respectively opened on the outer wall of the hinge pin shaft 3 and the outer wall of the first bushing 9, thereby forming a lubrication transfer of the inner and outer lubricating oils. In order to ensure the lubrication penetration effect, the inner and outer diameters of the first bushing 9 and the second bushing 10 are consistent to ensure the penetration of the oil.

[0038] In some embodiments, the hinged ends of the first hinge 1 and the second hinge 2 are inner groove opening structures; the first hinge 1 is made of rigid material; the second hinge 2 is made of flexible material and is provided with two; the two second hinges 2 are respectively abutted against the inner ends of the inner groove opening structure of the first hinge 1, and a limiting spacer 11 is sleeved on the hinge pin 3 between the two second hinges 2; the two ends of the limiting spacer 11 are respectively abutted against the corresponding second hinge 2 and second bushing 10.

[0039] In this embodiment, the structural view of the first hinge 1 and the second hinge 2 can be referred to in Figure 1 and Figure 2 As shown, specifically, the second hinge 2 is composed of a plurality of spring plates stacked to form a flexible structure. The advantage of adopting the above method is that the force is more stable and balanced, and the support is better. The second hinge 2 will deform after being subjected to a lateral force, and can play a good supporting and limiting role by being embedded between the first hinge 1 and the limiting spacer 11. At the same time, considering that the hinge pin 3 is relatively long due to its own structure, further, in some embodiments, the inner oil groove 6 is arranged along the axial direction of the hinge pin 3; the outer oil groove 16 is arranged along the radial direction of the first bushing 9. Specifically, the inner oil groove 6 is a linear structure, and the outer oil groove 16 is an annular structure.

[0040] In order to further provide the oil seepage effect between the various components, a seepage hole 17 is provided through the outer oil groove 16. Thus, lubrication can be performed on the inside and outside at the same time.

[0041] Through the above method, not only can good lubrication be ensured between various components, but also the arrangement and distribution of the lubricating oil circuit (first oil filling port 4, second oil filling port 5, inner oil guide channel 7, outer oil guide channel 8) and the oil storage tank (outer oil tank 16 and inner oil tank 6) can be more reasonable through corresponding combination, which is convenient for the introduction and storage of lubricating oil.

[0042] While considering the above-mentioned lubrication effect, it is also necessary to consider the sealing of each connection, and further include: a pin shaft top cover and a sealing cover plate 12, the pin shaft top cover and the sealing cover plate 12 are respectively arranged at both ends of the hinge pin shaft 3, and are respectively abutted against the outer ends of the groove opening structure in the first hinge part 1, and a sealing ring 13 is provided at the abutment.

[0043] like Figure 2 The hinge pin 3 is provided with sealing rings 13 at two times to prevent oil leakage. At the same time, the flexible material characteristics of the second hinge 2 are utilized to realize extrusion-type sealing, thereby ensuring that there is no leakage between the second hinge 2 and the first hinge 1 and between the second hinge 2 and the limiting spacer 11. In order to ensure its sealing structure, a corresponding sealing ring structure can also be added between the above two to achieve a multiple anti-oil leakage sealing effect.

[0044] In some embodiments, the fixed installation method of the hinge pin 3 is achieved based on the following structure, specifically including: a fastening nut 14, a pair of nut slots, and an anti-loosening pin; the fastening nut 14 is arranged on the outer side of the sealing cover 12 and is threadedly connected to the hinge pin 3; a pair of nut slots are symmetrically arranged on the fastening nut 14; the anti-loosening pin passes through a fixed through hole 15 on the hinge pin 3 and is arranged between a pair of nut slots.

[0045] The fast thread fastening is achieved by fastening the nut 14, and then the anti-loosening pin is inserted into the fixing through hole 15, and the radial limiting effect between the anti-loosening pin and a pair of nut slots is used to prevent the fastening nut 14 from loosening.

[0046] In order to ensure that the fixing through hole 15 is easily aligned with the pair of nut slots, a plurality of nut slots in an even number may be evenly distributed on the fastening nut 14 .

[0047] The utility model also discloses a mechanical wheel, comprising a flexible low-wear lateral stop mechanism hinged between an inner rim and an outer rim, such as any one of the above-mentioned implementation modes.

[0048] Its working principle is:

[0049] The core of this solution is to use an assembled spring plate to replace the connecting steel plate at one end, which reduces the weight while making the mechanism flexible; use internal and external oil grooves to store butter to change the sliding friction type between the parts from dry friction to boundary friction, and use the corresponding oil filling port to conveniently replenish butter so that the lubrication state can be maintained for a long time, thereby maximizing the mission and reliability of the equipment and contributing to the improvement of the handling performance of mechanical wheels (non-pneumatic tires).

[0050] The butter injected into the first oil filling port 4 enters the inner oil groove 6 through the inner oil guide channel 7, and the lubricating oil is distributed on the outer periphery of the hinge pin 3 through friction rotation; the butter injected into the second oil filling port 5 enters the outer oil groove 16 through the outer oil guide channel 8, and the lubricating oil is distributed on the outer periphery of the first bushing 9 and the second bushing 10 through friction rotation. At the same time, the lubricating oil can also enter the inner wall of the first bushing 9 through the leakage hole 17. Since the inner and outer diameters of the first bushing 9 and the second bushing 10 are consistent, the oil can be distributed between the various parts through penetration.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
