Abstract
Description
Technical Field
[0001] This disclosure relates to the field of vehicle parts technology, and more specifically, to a vibration absorber and a vehicle. Background Technology
[0002] Drive shaft vibration absorbers, as a commonly used vibration damping structure, are frequently assembled onto drive shafts to attenuate torsional vibrations in the transmission system. By absorbing and dissipating the torsional vibration energy on the drive shaft, they effectively reduce the vibration level of the transmission system, thereby improving the operational stability of the equipment, reducing noise, and extending its service life. However, existing drive shaft vibration absorbers typically only optimize and attenuate torsional vibrations of a single frequency. In actual operation, transmission systems often experience torsional vibrations of multiple frequencies, sometimes even two. If these vibrations are not effectively controlled, they can lead to fatigue damage, increased noise, and even functional failure in the transmission system. If a vibration absorber capable of absorbing two frequencies is used, the increased torsional frequency attenuation will cause the rubber spring in the absorber to deform excessively due to more complex dynamic stresses during operation, leading to wear and tear on the rubber spring and affecting the performance of the vibration absorber. Utility Model Content
[0003] The purpose of this disclosure is to provide a vibration absorber and a vehicle to solve the problem of easy damage to the rubber main spring when the torsional vibration frequency of the vibration absorber increases.

[0008] A second mass ring is connected to the outer periphery of the rubber main spring, and the first and second mass rings are respectively coaxially arranged with the mounting plate; and
[0009] A reinforcing member is embedded in the rubber main spring. The reinforcing member includes a first reinforcing member disposed between the mounting plate and the first mass ring, and a second reinforcing member disposed between the first mass ring and the second mass ring, and the reinforcing member is in contact with the rubber main spring.
[0010] Optionally, the rubber main spring includes a first main spring and a second main spring arranged concentrically, the second main spring being sleeved on the outside of the first main spring, a connecting post connecting the first main spring and the second main spring, the first mass ring being disposed between the first main spring and the second main spring, and the second mass ring being disposed on the outside of the second main spring.
[0011] Optionally, the first main spring includes a plurality of first torsion portions arranged circumferentially, and the second main spring includes a plurality of second torsion portions arranged circumferentially, with the first torsion portions and the second torsion portions being arranged in a one-to-one correspondence.
[0012] Optionally, the mounting plate is circumferentially spaced with a plurality of bosses protruding toward the first mass ring, and each of the first torsional portions is arranged between two adjacent bosses.
[0013] Optionally, the first reinforcing member includes a plurality of reinforcing plates located between the boss and the first mass ring, and the ends of the reinforcing plates are in contact with the first main spring.
[0014] Optionally, the first torsion portion includes:
[0015] The inner connecting section is attached to the outer periphery of the mounting plate;
[0016] An outer connecting segment is attached to the inner circumference of the first mass ring, and the outer connecting segment is connected to the connecting post;
[0017] The first main reinforcement bar connects the inner connecting section and the outer connecting section at both ends, and the connecting column is correspondingly arranged with the first main reinforcement bar; and
[0018] Multiple first protrusions are respectively arranged on both sides of the first main rib, and the multiple first protrusions on each side are staggered on the inner connecting section and the outer connecting section. When the rubber main spring deforms, at least some of the adjacent first protrusions can abut against each other.
[0019] Optionally, the second main spring includes an inner ring attached to the outer periphery of the first mass ring and an outer ring attached to the inner periphery of the second mass ring, wherein the inner ring is connected to the connecting post, and a plurality of second torsion portions are spaced apart between the inner ring and the outer ring, wherein the second torsion portion includes:
[0020] The second main reinforcement bar connects the inner ring and the outer ring at both ends, and the connecting column is correspondingly arranged with the second main reinforcement bar; and
[0021] Multiple second protrusions are respectively arranged on both sides of the second main rib, and the multiple second protrusions on each side are staggered on the inner ring and the ring.

[0025] Through the above technical solution, when the drive shaft vibrates, the vibration can be absorbed by the deformation of the rubber main spring and the inertia of the mass ring. The mass ring can be a first mass ring and a second mass ring nested inside and outside the vibration absorber, so that the vibration absorber can attenuate vibrations at two torsional frequencies. As the torsional frequency attenuated by the vibration absorber increases, the rubber main spring will face more complex dynamic stresses during operation. Therefore, a reinforcing member is set in the rubber main spring to reduce the creep of the rubber main spring during the operation of the vibration absorber. This not only ensures the dynamic balance of the vibration absorber but also ensures the strength of the rubber main spring, making it less prone to damage when subjected to large vibrations, thereby increasing the service life of the rubber main spring and reducing the failure rate of the vibration absorber.

Detailed Implementation
[0037] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0038] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined in relation to the outline of the corresponding components. The terms "first," "second," etc., are used to distinguish different components and are not sequential or significant. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.
[0039] According to one embodiment of this disclosure, such as Figures 1 to 7 As shown, a vibration absorber is provided, including a mounting plate 1, a rubber main spring 2, a first mass ring 3, a second mass ring 4, and a reinforcing member 5. The mounting plate 1 is used to mount onto a drive shaft. The rubber main spring 2 can be connected around the outer periphery of the mounting plate 1. The first mass ring 3 can be embedded in the rubber main spring 2, and the second mass ring 4 can be connected to the outer periphery of the rubber main spring 2. The first mass ring 3 and the second mass ring 4 are respectively coaxially arranged with the mounting plate 1. The reinforcing member 5 is embedded in the rubber main spring 2, and the reinforcing member 5 includes a first reinforcing member disposed between the mounting plate 1 and the first mass ring 3, and a second reinforcing member disposed between the first mass ring 3 and the second mass ring 4. The reinforcing member 5 is in contact with the rubber main spring 2.
[0040] Through the above technical solution, when the drive shaft vibrates, the vibration can be absorbed by the deformation of the rubber main spring 2 and the inertia of the mass ring. The mass ring can be a first mass ring 3 and a second mass ring 4 nested inside and outside the vibration absorber, so that the vibration absorber can attenuate vibrations at two torsional frequencies. As the torsional frequency attenuated by the vibration absorber increases, the rubber main spring 2 will face more complex dynamic stresses during operation. Therefore, a reinforcing member 5 is provided in the rubber main spring 2 to reduce the creep of the rubber main spring 2 during the operation of the vibration absorber. This not only ensures the dynamic balance of the vibration absorber but also ensures the strength of the rubber main spring 2, making it less prone to damage when subjected to large vibrations, thereby increasing the service life of the rubber main spring 2 and reducing the failure rate of the vibration absorber.
[0041] It should be noted that the reinforcing member 5 can be made of nylon. Nylon has high strength, which can reduce the creep of the rubber main spring 2 during the operation of the vibration absorber and ensure the dynamic balance of the vibration absorber. At the same time, since nylon is lightweight, it can also reduce the impact of its weight on the overall vibration absorber. The reinforcing member 5 can also be made of other high-strength and low-weight materials, and this disclosure does not limit it.
[0042] Furthermore, such as Figure 1 and Figure 2 As shown, the rubber main spring 2 may include a first main spring 21 and a second main spring 22 arranged concentrically. The second main spring 22 is sleeved on the outside of the first main spring 21. A connecting post 23 connects the first main spring 21 and the second main spring 22. A first mass ring 3 is disposed between the first main spring 21 and the second main spring 22, and a second mass ring 4 is disposed on the outside of the second main spring 22. The arrangement of the connecting post 23 not only enhances the structural strength of the rubber main spring 2, but also makes the connection between the first mass ring 3 and the second mass ring 4 and the rubber main spring 2 more stable, further improving the overall performance of the vibration absorber. The concentric arrangement of the first main spring 21 and the second main spring 22 allows the vibration absorber to distribute stress more evenly when subjected to vibration, avoiding damage caused by stress concentration. Here, there can be multiple connecting posts 23, arranged at intervals along the circumference of the rubber main spring 2. The connecting posts 23 can pass through the first mass ring 3, and their two ends are connected to the first main spring 21 and the second main spring 22 respectively, thereby improving the connection strength between the first main spring 21 and the second main spring 22. The specific number of connecting posts 23 can be set according to the size of the rubber main spring 2, and this disclosure does not limit it.
[0043] Furthermore, such as Figure 1 and Figure 2As shown, the first main spring 21 may include a plurality of circumferentially arranged first torsion portions 201, and the second main spring 22 includes a plurality of circumferentially arranged second torsion portions 202, with the first torsion portions 201 and the second torsion portions 202 arranged in a one-to-one correspondence. This correspondence between the first torsion portions 201 and the second torsion portions 202 allows the rubber main spring 2 to better maintain its shape when subjected to vibration, avoiding damage caused by stress concentration. This also allows the first main spring 21 and the second main spring 22 to distribute stress more evenly during deformation, thereby improving their durability and vibration absorption effect.
[0044] Furthermore, such as Figure 1 and Figure 2 As shown, the first torsion section 201 includes an inner connecting section 211, an outer connecting section 212, a first main rib 213, and a plurality of first protrusions 214. The inner connecting section 211 is attached to the outer periphery of the mounting plate 1, the outer connecting section 212 is attached to the inner periphery of the first mass ring 3, and the outer connecting section 212 is connected to the connecting post 23. The two ends of the first main rib 213 are connected to the inner connecting section 211 and the outer connecting section 212, and the connecting post 23 is correspondingly positioned to correspond with the first main rib 213. Multiple first protrusions 214 are respectively arranged on both sides of the first main rib 213, and the multiple first protrusions 214 on each side are staggered on the inner connecting section 211 and the outer connecting section 212. When the rubber main spring 2 deforms, at least some of the adjacent first protrusions 214 can abut against each other, so that they can contact each other when the first main rib 213 deforms at a large angle, thereby protecting the first main rib 213 and enabling the first main spring 21 to better maintain its shape, avoid damage caused by stress concentration, and improve its durability and vibration absorption effect. Taking two first protrusions 214 on each side of the first main rib 213 as an example, when the first main rib 213 deforms at a large angle clockwise, the two first protrusions 214 on one side can contact and abut against each other to protect the first main rib 213. When the first main rib 213 deforms at a large angle counterclockwise, the two first protrusions 214 on the other side can contact and abut against each other to protect the first main rib 213. The gap between adjacent first protrusions 214 can be 1.5-2mm, and this gap can be smaller than the distance between the first protrusion 214 and the first main reinforcement 213. This ensures effective protection of the first main reinforcement 213 under large corner conditions. In addition, the first protrusions 214 on both sides of the first main reinforcement 213 can be arranged symmetrically with the first main reinforcement 213 as the central axis, thereby improving the protective effect on the first main reinforcement 213. That is, the first protrusions 214 on the side closer to the first main reinforcement 213 can be all set on the outer connecting section 212 or all set on the inner connecting section 211. This disclosure does not limit this.
[0045] It should be noted that the mounting plate 1 can also have multiple protrusions 11 extending towards the first mass ring 3 at circumferential intervals, with each first torsional portion arranged between two adjacent protrusions 11. In this way, the first main spring 21 can be divided into multiple parts, and the protrusions 11 can also limit the first main spring 21 under large rotation angle conditions, reducing the probability of the first main spring 21 breaking. In addition, the mounting plate 1 can also be provided with multiple mounting holes for external connection, and the mounting holes can be configured one-to-one with the protrusions 11. The number of protrusions 11 can be set according to the size of the vibration absorber, and can be formed at equal intervals on the mounting plate 1. The number can be four or six, and this disclosure does not limit this.
[0046] Furthermore, such as Figure 1 and Figure 7 As shown, the first reinforcing member may further include multiple reinforcing plates 51, which are located between the boss 11 and the first mass ring 3, and the ends of the reinforcing plates 51 can contact the first main spring 21. Without affecting the torsional stiffness, the reinforcing plates 51 can effectively reduce the creep of the first main spring 21 between the mounting plate 1 and the first mass ring 3, thereby ensuring the overall dynamic balance of the vibration absorber. Taking the first main spring 21 mentioned above as an example, it may include an inner connecting section 211 attached to the outer periphery of the mounting plate 1 and an outer connecting section 212 attached to the inner periphery of the first mass ring 3. Here, the ends of the inner connecting section 211 and the outer connecting section 212 can be connected together, so that the inner connecting section 211 and the outer connecting section 212 between every two bosses 11 form a ring. The end of the reinforcing piece 51 can contact the ring. The surface of the reinforcing piece 51 can be formed with a plurality of fourth protrusions 511. The fourth protrusions 511 can further reduce the contact area between the fourth protrusions 511 and the first mass ring 3, thereby reducing the friction. The thickness of the thickest part of the reinforcing piece 51 is 0.1-0.2 mm smaller than the distance between the bosses 11 and the first mass ring 3.
[0047] According to one embodiment of this disclosure, such as Figures 1 to 6As shown, the second main spring 22 may include an inner ring 221 attached to the outer periphery of the first mass ring 3 and an outer ring 222 attached to the inner periphery of the second mass ring 4. The inner ring 221 is connected to the connecting post 23. A plurality of second torsion portions 202 are spaced apart between the inner ring 221 and the outer ring 222. The second torsion portion 202 may include a second main rib 223 and a plurality of second protrusions 224. The two ends of the second main rib 223 are connected to the inner ring 221 and the outer ring 222, and the connecting post 23 is correspondingly arranged with the second main rib 223. Multiple second protrusions 224 can be arranged on both sides of the second main rib 223, and the multiple second protrusions 224 on each side are staggered on the inner ring 221 and the ring 222. When the rubber main spring 2 deforms, at least some of the adjacent second protrusions 224 can abut against each other, so that they can contact each other when the second main rib 223 deforms at a large angle, thereby protecting the second main rib 223. This allows the second main spring 22 to better maintain its shape, avoid damage caused by stress concentration, and improve its durability and vibration absorption effect. Taking three second protrusions 224 on each side of the second main rib 223 as an example, regardless of whether the second main rib 223 deforms at a large angle clockwise or counterclockwise, two second protrusions 224 on each side can contact and abut against each other to protect the second main rib 223. The gap between adjacent second protrusions 224 can be smaller than the distance between the second protrusion 224 and the second main rib 223, thus ensuring effective protection of the second main rib 223 under large angle conditions. In addition, the second protrusions 224 on both sides of the second main reinforcement 223 can be arranged symmetrically with the second main reinforcement 223 as the central axis, thereby improving the protective effect on the second main reinforcement 223. Taking the setting of three second protrusions 224 on each side of the second main reinforcement 223 as an example, two second protrusions 224 can be arranged at intervals on the outer ring 222, and another second protrusion 224 can be arranged on the inner ring 221, and the gap between them corresponds to the gap between the two second protrusions 224 on the outer ring 222.
[0048] According to one embodiment of this disclosure, such as Figures 1 to 6As shown, the second reinforcing member may further include multiple reinforcing pins 52, and the second main spring 22 may further include multiple reinforcing pin limiting portions 203. The reinforcing pin limiting portions 203 are disposed between two adjacent second torsional portions 202, and the reinforcing pins 52 are correspondingly disposed in the reinforcing pin limiting portions 203. The number and position of the reinforcing pins 52 may correspond one-to-one with those of the reinforcing plates 51 mentioned above. Without affecting the torsional stiffness, the reinforcing pins 52 can effectively reduce the creep of the second main spring 22 between the first mass ring 3 and the second mass ring 4, thereby ensuring the overall dynamic balance of the vibration absorber. The structure of the reinforcing pin 52 may include a connecting rod 521, with a limiting cap 522 at each end of the connecting rod 521 and a cap ear 523 formed on each side of the limiting cap 522. The surface edges of the limiting cap 522 and the cap ear 523 on the side away from the connecting rod 521 may be chamfered to facilitate the reinforcing pin 52 being pressed into the reinforcing pin limiting part 203. The surface edges of the limiting cap 522 and the cap ear 523 on the side near the connecting rod 521 may not be chamfered to prevent the reinforcing pin 52 from coming out due to vibration after being pressed into the reinforcing pin limiting part 203. The reinforcing pin limiting part 203 may include four third protrusions 225. These four third protrusions 225 can be arranged in pairs opposite to each other on the inner ring 221 and the outer ring 222. Two adjacent third protrusions 225 on the inner ring 221 or the outer ring 222 form an arc, and the two arcs are concentrically arranged to form a circle, i.e., a gap circle is formed between the four third protrusions 225. The diameter D1 of this gap circle is 0.1-0.2 mm larger than the diameter of the connecting rod 521. The gap d1 between two oppositely arranged third protrusions 225 on the inner ring 221 and the outer ring 222 is not greater than the radius of the gap circle. The diameter D2 of the limiting cap 522 can be 2-3 mm larger than the diameter D1 of the gap circle and 1-2 mm smaller than the distance between the first mass ring 3 and the second mass ring 4. The width d2 of the cap lug 523 is smaller than the gap d1 between two oppositely arranged third protrusions 225 on the inner ring 221 and the outer ring 222, thereby facilitating pressing.
