[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0039] Please refer to Figures 1 to 8 , and now the rubber bushing mount and vehicle provided by the present utility model will be described. The rubber bushing mount includes an upper limit plate 1, a lower limit plate 4, a mount body and a limit rubber assembly; the upper limit plate 1, the mount body and the lower limit plate 4 are connected by bolts; the mount body includes a bushing and a skeleton 3 sleeved outside the bushing; the bushing includes a rubber sleeve 7 and an inner core 6; the limit rubber assembly includes a first limit rubber 5 and a second limit rubber 13; the first limit rubber 5 is located at the top of the rubber sleeve 7, and the second limit rubber 13 is located at the top of the lower limit plate 4; both the first limit rubber 5 and the second limit rubber 13 include a plurality of first rubber blocks and a plurality of second rubber blocks, and the thickness of the first rubber blocks along the axial direction of the mount body is greater than the thickness of the second rubber blocks along the axial direction of the mount body; the first rubber blocks and the second rubber blocks are alternately distributed and there is a gap between adjacent first rubber blocks and second rubber blocks.
[0040] The bolt passes through the upper limit plate 1, the mount body and the lower limit plate 4 to form a suspended integral structure, wherein the mount body includes a skeleton 3, and the skeleton 3 is connected to the vehicle body; the bolt makes the mount body unable to move in the radial direction and only has a small degree of freedom in the Z direction along the length direction of the bolt, and the mount body moves up or down along the bolt under the action of the skeleton 3. Taking the axial direction of the bolt as the longitudinal direction, the upper limit plate 1 is located above the mount body, and the lower limit plate 4 is located below the mount body. When the mount body moves up under the action of the skeleton 3, the mount body approaches the upper limit plate 1; when the mount body moves down under the action of the skeleton 3, the mount body approaches the lower limit plate 4.
[0041] When the mount body moves up, the mount body moves in the direction close to the upper limit plate 1. At this time, the first limit rubber 5 is squeezed and deformed to achieve the damping effect; when the mount body moves down, the mount body moves in the direction close to the lower limit plate 4. At this time, the second limit rubber 13 is squeezed and deformed to achieve the damping effect.
[0042] Both the first limit rubber and the second limit rubber are annular, and their thickness directions are consistent with the axial direction of the bolt. The bolt is coaxial with the mount body, the upper limit plate and the lower limit plate. The size of the raised rubber blocks on the first limit rubber and the second limit rubber in the thickness direction can be divided into first rubber blocks and second rubber blocks.
[0043] Compared with the prior art, the rubber bushing mount provided by the present utility model arranges both the first limiting rubber 5 and the second limiting rubber 13 such that the first rubber blocks and the second rubber blocks are evenly distributed at intervals. When the mount body moves upward or downward, it first squeezes the first rubber blocks, and then squeezes downward onto the second rubber blocks; the first rubber blocks and the second rubber blocks are distributed at intervals, improving the uniformity of the pressure distribution of the first rubber blocks and ensuring the bearing area. When continuously squeezed and deformed, the first rubber blocks deform until the end faces of the first rubber blocks are flush with the end faces of the second rubber blocks, further increasing the bearing area of the limiting rubber and the uniformity of the pressure distribution, thereby improving the durability; and there is a gap between the first rubber blocks and the second rubber blocks to facilitate adapting to the deformation of the first rubber blocks along their length directions, reducing the extrusion force between the first rubber blocks and the second rubber blocks, and further ensuring the force uniformity and durability of the first rubber blocks and the second rubber blocks.
[0044] As Figure 3 and Figure 6 shown, the trajectories of both the first limiting rubber 5 and the second limiting rubber 13 are annular, and both the first limiting rubber 5 and the second limiting rubber 13 include first rubber blocks and second rubber blocks, where the width of the first rubber blocks is smaller than the width of the second rubber blocks. When the first rubber blocks are squeezed under force, their width is smaller and they are prone to deformation; until the end faces of the first rubber blocks are flush with the end faces of the second rubber blocks, both the first rubber blocks and the second rubber blocks bear the force, facilitating bearing a larger pressure. Reducing the width of the first rubber blocks can further facilitate the deformation of the first rubber blocks and provide a space for the deformation of the first rubber blocks, thereby increasing the service life of the first rubber blocks.
[0045] Taking the first limiting rubber 5 as an example, the first limiting rubber 5 is annular, and the first limiting rubber 5 is arranged around the outer side of the upper end of the rubber sleeve, forming a flanging structure at the upper end of the rubber sleeve. The first limiting rubber also includes a rubber bottom layer, the rubber bottom layer is connected to the rubber sleeve, and both the first rubber blocks and the second rubber blocks are located on the upper end face of the rubber bottom layer and are integrally formed with the rubber bottom layer.
[0046] Both the first rubber blocks and the second rubber blocks protrude from the upper end face of the rubber bottom layer. The first rubber blocks have a trapezoidal longitudinal cross-section structure, and the second rubber blocks have a rectangular longitudinal cross-section structure. Optionally, the thickness of the first rubber blocks is greater than the thickness of the second rubber blocks. For example, the thickness of the first rubber blocks is 2 times the thickness of the second rubber blocks. The width of the first rubber blocks along the radial direction of the rubber bottom layer is one-half of the width of the second rubber blocks along the radial direction of the rubber bottom layer. As Figure 3 shown, the first limiting rubber 5 has two first rubber blocks and two second rubber blocks. The two first rubber blocks are symmetrically arranged, the two second rubber blocks are symmetrically arranged, and the first rubber blocks and the second rubber blocks are alternately arranged. The width of the gap between any two rubber blocks is the same, ensuring the force uniformity between the mount body and the upper limiting plate 1.
[0047] Optionally, the outer edge of the rubber bottom layer 9 has an annular stepped structure, and the outer edge of the second rubber block is flush with the inner edge of the annular stepped structure. The inner edge of the rubber bottom layer 9 is vulcanized to the upper edge of the rubber sleeve.
[0048] Similarly, as Figure 6 shown, the width of the first rubber block of the second limiting rubber 13 is also smaller than that of the second rubber block, which can improve the service life of the first rubber block.
[0049] In some possible embodiments, please refer to Figures 3 to 5 , the rubber sleeve 7 is an annular cylinder, and the inner side of the rubber sleeve 7 has an extension part 12, and the extension part 12 is connected to the inner core 6; an arc-shaped hole 10 is formed in the extension part 12, and the depth direction of the arc-shaped hole 10 is consistent with the axial direction of the suspension body.
[0050] The suspension body includes a skeleton 3 connected to the vehicle body and a bushing pressed inside the skeleton 3. The bushing includes a rubber sleeve 7 and an inner core 6. During installation, the inner core 6 is located inside the rubber sleeve 7 and is connected to the rubber sleeve 7 by means of the extension part 12; after the rubber sleeve 7 and the inner core 6 form an integral bushing, they are pressed tightly in the inner cavity of the skeleton 3.
[0051] Specifically, the extension part 12 is vulcanized rubber, and the vulcanized rubber forms an integral body with the rubber sleeve 7. The extension part 12 is distributed radially along the suspension body, and an arc-shaped hole 10 extending along the axial direction of the suspension body is formed in the extension part 12, and the arc-shaped hole 10 penetrates the entire extension part 12. The setting of the arc-shaped hole 10 enables the rubber sleeve 7 and the inner core 6 to buffer the circumferential force, achieving a damping effect and further improving the damping effect.
[0052] Optionally, there are multiple arc-shaped holes 10, and the multiple arc-shaped holes 10 are evenly distributed on the extension part 12. The evenly distributed multiple arc-shaped holes 10 can make the circumferential force received by the rubber sleeve 7 evenly distributed, so that the forces on each part of the rubber sleeve 7 are evenly distributed.
[0053] As Figure 4 and Figure 5 shown, the multiple arc-shaped holes 10 correspond to the multiple second rubber blocks on the first limiting rubber 5 one by one, and the arc-shaped holes 10 are located inside the second rubber blocks. The extension part 12 corresponds to the first rubber block and provides sufficient support strength for the first rubber block; while the arc-shaped holes 10 corresponding to the second rubber blocks do not affect the support strength of the first rubber block, and at the same time achieve the damping effect.
[0054] In some possible embodiments, please refer to Figures 3 to 5 , the outer side of the inner core 6 has a protruding ring 11, the protruding ring 11 is connected to the extension part 12, and the length of the protruding ring 11 along the axial direction of the inner core 6 is the same as the longitudinal length of the extension part 12.
[0055] The protruding ring 11 is a vulcanized rubber layer. The outer side of the protruding ring 11 is connected to the extension part 12. The protruding ring 11 and the extension part 12 are integrally vulcanized and formed to ensure the connection strength and connection stability between the extension part 12 and the inner core 6. In some possible embodiments, please refer to Figure 2 , the upper limit plate 1 is an annular plate-like structure. The middle part of the upper limit plate 1 has a circular groove 2. The circular groove 2 is provided with a central hole allowing a bolt to penetrate through; the first limiting rubber 5 is located outside the circular groove 2 and fits on the lower end face of the upper limit plate 1.
[0056] The lower end face of the circular groove 2 opened in the middle part of the upper limit plate 1 abuts against the upper end face of the inner core 6. The flanging structure 8 at the upper end of the rubber sleeve 7 outside the inner core 6 is higher than the inner core 6, and the first limiting rubber 5 at the upper end of the flanging structure 8 fits on the lower end face of the plate body of the upper limit plate 1, and the first limiting rubber 5 is located outside the circular groove 2. The arrangement of the circular groove 2 allows the upper limit plate 1 to fit the inner core 6 while leaving a accommodation space for the first limiting rubber 5; at the same time, the side wall of the circular groove 2 restricts the deformation direction of the first limiting rubber 5.
[0057] In some possible embodiments, please refer to Figure 6 , the center of the lower limit plate 4 has a circular tube 14. The circular tube 14 protrudes upward. The circular tube 14 is sleeved outside the inner core 6; there is a gap between the outer side of the circular tube 14 and the second limiting rubber 13, and the upper end of the circular tube 14 is flush with the upper end face of the first rubber block of the second limiting rubber 13.
[0058] The outer edge of the lower end face of the lower limit plate 4 slopes upward. There is a bolt hole left in the center of the lower limit plate 4. A circular tube 14 is welded in the middle of the upper end face of the lower limit plate 4. The circular tube 14 is coaxial with the lower limit plate 4. The upper end face of the lower limit plate 4 forms an annular limiting surface inside the circular tube 14. This limiting surface is located around the bolt hole. During installation, the inner core 6 is inserted into the circular tube 14 until the lower end face of the inner core 6 abuts against the limiting surface of the lower limit plate 4, and the inner side wall of the circular tube 14 fits against the outer side wall of the inner core 6 to improve the connection stability between the lower limit plate 4 and the inner core 6. The protruding ring 11 of the inner core 6 is located above the circular tube 14.
[0059] The second limiting rubber 13 is located in the circumferential direction of the circular tube 14. The second limiting rubber 13 includes a plurality of first rubber blocks and a plurality of second rubber blocks. The first rubber block is a structure with a rectangular longitudinal section, and the first rubber block is arc-shaped. The second rubber block is a structure with a trapezoidal longitudinal section. The second limiting rubber 13 includes four first rubber blocks and four second rubber blocks. The four first rubber blocks and the four second rubber blocks are evenly distributed and have strong pressure resistance.
[0060] In some possible embodiments, please refer to Figure 7 and Figure 8, the skeleton 3 includes a cylindrical frame body 15 and an annular limiting plate 16, and the annular limiting plate 16 is located at the lower end of the cylindrical frame body 15; the bushing is press-fitted downward within the cylindrical frame body 15, such that the flanging structure 8 is lapped on the upper end surface of the cylindrical frame body 15, the lower end of the inner core 6 penetrates through the central hole of the annular limiting plate 16, and the lower end of the rubber sleeve 7 abuts against the upper end surface of the annular limiting plate 16.
[0061] The cylindrical frame body 15 connects to the connecting arm of the skeleton 3 and is connected to the vehicle body by means of the connecting arm. The lower end of the cylindrical frame body 15 is connected to the annular limiting plate 16. The central hole of the annular limiting plate 16 is for a bolt to penetrate through, and the annular limiting plate 16 is for fitting against the lower end surface of the bushing. The inner side wall of the cylindrical frame body 15 and the annular limiting plate 16 cooperate to form a groove body in the inner circumferential direction of the cylindrical frame body 15; the bushing is press-fitted within the groove body.
[0062] During installation, the bushing is pressed into the groove body of the cylindrical frame body 15. The circumferential side wall of the bushing fits against the inner side wall of the cylindrical frame body 15, and the lower end of the bushing extends downward to abut against the annular limiting plate 16. At this time, the flanging structure 8 at the upper end of the bushing fits against the upper end surface of the cylindrical frame body 15. At this time, the central hole of the inner core 6 and the central hole of the annular limiting plate 16 are coaxially communicated.
[0063] The lower end surface of the annular limiting plate 16 fits against the upper end of the second limiting rubber 13, increasing the fitting area between the suspension body and the second limiting rubber 13, ensuring the uniform force on the second limiting rubber 13, and improving the vibration damping effect.
[0064] When the suspension is working, the upper limiting plate 1, the inner core 6 of the bushing, and the lower limiting plate 4 are fixed by bolts. The skeleton 3 drives the rubber to move between the upper and lower limiting plates 4, can bear a certain Z-direction force, and achieves the damping effect by means of the first limiting rubber 5 and the second limiting rubber 13. In addition, this suspension has a simple structure and is easy to assemble, only requiring one bolt for fixation, and the overall structure is cylindrical. Under the fixation of the bolt, the suspension structure can achieve three-directional limitation and is suitable for shock absorption of small motors, main reducers, compressors, etc.
