Technical Field
[0001] This utility model belongs to the field of vehicle shock absorption technology, specifically relating to a suspension shock absorber and a vehicle. Background Technology
[0002] The power mount plays a crucial connecting role between the vehicle's powertrain and supporting structures such as the chassis or subframe. As the main damping system of the powertrain, its primary purpose is to reduce the vibration and noise generated by the powertrain, such as the engine or electric motor, during operation. Since the main damping system cannot effectively filter vibrations across all frequency bands, a spring-mass system is typically added to absorb vibrations in specific frequency ranges. However, adding a spring-mass system significantly complicates the overall powertrain mounting structure, poses a significant challenge to the engine compartment's internal space, and is detrimental to lightweighting and cost control. Therefore, there is an urgent need to improve existing power mount solutions to overcome these problems. Utility Model Content

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: Firstly, a suspended vibration absorber is provided, comprising:
[0005] The suspension body includes an outer frame and an inner core arranged coaxially, and a rubber main spring connected between the outer frame and the inner core; the outer frame is connected to the frame side or the subframe side, the inner core has a core hole, and one end of the inner core abuts against the powertrain side;
[0006] The fastener has one end that passes through the core hole and is connected to the powertrain side, and the other end that forms a fastening head. The fastening head abuts against the end face of the inner core away from the powertrain side.
[0007] The vibration damping module, connected to the fastening head, is used to attenuate the vibration of the suspension body.
[0008] In conjunction with the first aspect, in one possible implementation, the fastening head includes a fastening section and a screwing section that are connected as one unit; wherein, the fastening section abuts against the inner core, and the diameter or circumscribed circle diameter of the screwing section is smaller than the diameter or circumscribed circle diameter of the fastening section; the vibration-absorbing module is sleeved and fixed to the peripheral wall of the fastening section.
[0009] In some embodiments, the vibration absorption module includes:
[0010] The first connecting core has a first connecting hole at one end, which is sleeved and fixed to the fastening section, and the first connecting hole has an internal space to accommodate the screwing section.
[0011] The first mass block is fitted and fixed to the outer periphery of the first connecting core.
[0012] For example, the first connecting hole is screwed to the fastening section, and the end of the first connecting core facing away from the fastening section is provided with a first operating head; a first flexible spacer sleeve is provided between the first connecting core and the first mass block.
[0013] For example, the first operating head has a shape that matches the outer periphery of the screwing section.
[0014] In conjunction with the first aspect, in one possible implementation, the fastening head has a second connecting hole at the center of its end face away from the inner core, and the vibration absorption module includes a second connecting core and a second mass block; wherein, one end of the second connecting core is connected to the second connecting hole, and the second mass block is fitted around the outer periphery of the second connecting core.
[0015] In some embodiments, the second connecting core includes a connecting post, an intermediate post, and a second operating head connected in sequence; wherein the connecting post is threadedly connected to the second connecting hole; a second flexible spacer sleeve is sleeved on the outer periphery of the intermediate post, and a second mass block is sleeved on the outer periphery of the second flexible spacer sleeve.
[0016] In conjunction with the first aspect, in one possible implementation, the fastening head has an extension post on the side opposite to the inner core, and the vibration absorption module includes a core sleeve and a third mass block; wherein the core sleeve is sleeved and fixed to the extension post, and the third mass block is sleeved on the outer periphery of the core sleeve.
[0017] For example, the outer periphery shape of the core sleeve is consistent with the outer periphery shape of the fastening head, and the outer periphery of the core sleeve is provided with a third flexible spacer sleeve, and the third mass block is sleeved on the outer periphery of the third flexible spacer sleeve.
[0018] For example, the end of the core sleeve opposite the fastening head is closed and forms a third operating head.
[0019] The beneficial effects of the suspension vibration absorber provided by this utility model are as follows: Compared with the prior art, the suspension vibration absorber of this utility model is connected to the frame side or subframe side through the outer frame, and one end of the fastener passes through the inner core and is connected to the powertrain side to connect the inner core to the powertrain side. The rubber main spring between the outer frame and the inner core absorbs vibration. On this basis, the fastening head formed by the end of the fastener away from the inner core is connected to the vibration absorption module. The vibration absorption module absorbs and attenuates the vibration of the suspension body, thereby achieving frequency avoidance and improving the vibration reduction effect. By setting the fastening head at the end of the fastener as the installation base of the vibration absorption module, the overall structure is simple and compact, occupies little space, which is not only conducive to lightweight indicators and cost control, but also facilitates the layout and installation of the powertrain in the engine compartment space.
[0020] The tightening head has a screw-on section to facilitate the installation of a torque wrench for tightening. After tightening, the tightening section abuts against the end of the inner core, thereby fixing the inner core to the powertrain side. At the same time, the tightening section also serves as the mounting base for the vibration absorption module. In order to facilitate the vibration absorption module to be fitted onto the tightening section, the diameter or circumscribed circle diameter of the screw-on section is set to be less than or equal to the diameter or circumscribed circle diameter of the tightening section.
[0021] The vibration absorption module can be fixed by a sleeve between the first connecting core and the fastening section, and a first mass block can be mounted on the first connecting core. The first mass block can be used to adjust the overall mode of the system, eliminate or reduce vibration at a specific frequency to avoid resonance.
[0022] The same torque wrench can be used to apply torque to the screwing section and the first operating head, thereby improving the convenience of installation. The first connecting core can be screwed onto the fastening section in a threaded manner by screwing the first operating head. By setting the first flexible spacer between the first connecting core and the first mass block, the flexible buffering effect of the first flexible spacer can be used to absorb and attenuate vibration energy, reduce the vibration amplitude, and thus improve the vibration reduction effect.
[0023] The vibration absorption module can also be connected to the fastening head by inserting the second connecting core into the second connecting hole to form a tight fit. The connection structure is simple and compact. By mounting a second mass block on the second connecting core, the overall mode of the system can be adjusted to eliminate or reduce vibrations at specific frequencies to avoid resonance.
[0024] The second connecting core adopts a three-section structure. The second operating head and the fastening head can apply torque with the same torque wrench, which facilitates the assembly operation. By screwing the second operating head, the connecting column can be connected to the second connecting hole in a threaded manner, which is simple and reliable. The second flexible spacer sleeve can form a flexible buffer between the second mass block and the intermediate column, thereby absorbing and attenuating vibration energy, reducing vibration amplitude, and improving the vibration reduction effect.
[0025] The vibration absorption module can also be fixed by forming a sleeve fit between the core sleeve and the extended post set on the fastening head, which makes the structure simpler and more compact; and the third mass block set on the outer periphery of the core sleeve is used to adjust the overall mode of the system, eliminate or weaken the vibration of a specific frequency to avoid resonance.
[0026] Since the outer circumference of the core sleeve is consistent with the outer circumference of the fastening head, the same torque wrench can be used to apply torque to the fastening head and the core sleeve, thereby meeting the threaded connection assembly requirements between the fastener and the powertrain side, and between the core sleeve and the fastening head, and improving the convenience of assembly operations; the use of the third flexible spacer sleeve can form a flexible buffer between the third mass block and the core sleeve, thereby absorbing and attenuating vibration energy, reducing vibration amplitude, and helping to improve the vibration reduction effect.
[0027] The core sleeve can also be equipped with a third operating head at its end. The third operating head can be used to close the port of the core sleeve, thereby improving the structural strength of the core sleeve. On the other hand, a torque wrench adapted to the fastening head can be used to apply torque to the third operating head, thereby screwing the core sleeve onto the fastening head. The operation is simple and convenient.
[0028] Secondly, this utility model embodiment also provides a vehicle including the above-mentioned suspension shock absorber.
[0029] The beneficial effects of the vehicle provided by this utility model are as follows: Compared with the prior art, the vehicle of this utility model adopts the above-mentioned suspension vibration absorber, which is connected to the frame side or subframe side through the outer frame. One end of the fastener passes through the inner core and is connected to the powertrain side to connect the inner core to the powertrain side. The rubber main spring between the outer frame and the inner core absorbs vibration. On this basis, the fastening head formed by the end of the fastener away from the inner core is connected to the vibration absorption module. The vibration absorption module absorbs and attenuates the vibration of the suspension body, thereby achieving frequency avoidance and improving the vibration reduction effect. By setting the fastening head at the end of the fastener as the installation base of the vibration absorption module, the overall structure is simple and compact, occupies little space, which is not only conducive to lightweight indicators and cost control, but also facilitates the layout and installation of the powertrain in the engine compartment space.

[0039] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, 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 merely illustrative of the present utility model and are not intended to limit the present utility model.
[0040] It should be noted that when an element is referred to as being "set on" or "connected to" another element, it can be directly on or indirectly on the other element. It should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly defined.
[0041] Please refer to the following: Figures 1 to 8 The suspension vibration absorber provided by this utility model will now be described. The suspension vibration absorber includes a suspension body 10, a fastener 20, and a vibration absorption module 30; wherein, the suspension body 10 includes an outer frame 11 and an inner core 12 arranged coaxially, and a rubber main spring 13 connected between the outer frame 11 and the inner core 12; the outer frame 11 is connected to the frame side or the subframe side, the inner core 12 has a core hole 121, and one end of the inner core 12 abuts against the powertrain side; one end of the fastener 20 passes through the core hole 121 and is connected to the powertrain side, and the other end forms a fastening head 21, which abuts against the end face of the inner core 12 away from the powertrain side; the vibration absorption module 30 is connected to the fastening head 21 and is used to attenuate the vibration of the suspension body 10.
[0042] It should be noted that the frame is part of the vehicle's main body, and its function is to support various power equipment such as the engine and electric motor. The subframe is the skeleton of the front and rear axles, and its function is to improve suspension stiffness and isolate vibrations. The subframe is not a necessary component of the vehicle and is usually only found in high-end sedans and off-road vehicles. In this embodiment, the outer frame 11 can be connected to the subframe side for vehicles with a subframe, and to the frame side for vehicles without a subframe. The specific connection method is usually that the frame side or the subframe side has a cantilever that fits onto the outer frame 11.
[0043] For the powertrain side, such as an engine or electric motor, in this embodiment, the fastener 20 passes through the inner core 12 and is fastened to the threaded hole on the powertrain side, so that one end of the inner core 12 abuts against the powertrain side, and the other side is provided with axial pressure by the fastening head 21, thereby fixing the inner core 12 to the powertrain side; here the fastener 20 can be a bolt, and the nut part of the bolt is used as the fastening head 21. Of course, considering the connection between the vibration absorption module 30 and the fastening head 21, the bolt used here can be a double-ended bolt, that is, the nut has a screw structure on both sides.
[0044] In this embodiment, the rubber main spring 13 can be a soft material with more than 80% rubber as the main structure, while other structures such as the support frame can be made of hard materials such as metal or plastic. The outer frame 11 and the inner core 12 can be vulcanized and fixed as an integral structure with the rubber main spring 13. The rubber main spring 13 establishes a flexible connection between the outer frame 11 and the inner core 12 to buffer the transmission of vibration energy.
[0045] The vibration absorption module 30 can be specifically considered as an elastic or rigid mass block. Its function is to generate and excite a force opposite to the vibration frequency of the suspension body 10, thereby attenuating the vibration of the suspension body 10 and preventing resonance. It has a significant attenuation effect, especially for high-frequency vibration. It can also be understood that the function of the vibration absorption module 30 is to eliminate or weaken specific vibration frequencies such as high-frequency vibration, thereby improving the overall vibration reduction effect of the system (i.e., the overall structure of the suspension vibration absorber provided in this embodiment).
[0046] It should be noted that in this embodiment, after the vibration absorption module 30 is connected to the inner core 12 via the fastener 20, it can abut against the rubber main spring 13, or a gap can be formed between it and the rubber main spring 13, so that the operating wrench can be inserted into the gap to engage the inner core 12 or the fastening head 21 for auxiliary fastening operation, thereby improving the convenience of operation and the reliability of fastening.
[0047] Compared with the prior art, the suspension vibration absorber provided in this embodiment is connected to the vehicle frame side or subframe side through the outer frame 11, and one end of the fastener 20 passes through the inner core 12 and connects to the powertrain side to connect the inner core 12 to the powertrain side. The rubber main spring 13 between the outer frame 11 and the inner core 12 absorbs vibration. On this basis, the fastening head 21 formed by the end of the fastener 20 away from the inner core 12 is connected to the vibration absorption module 30. The vibration absorption module 30 absorbs and attenuates the vibration of the suspension body 10, thereby achieving frequency avoidance and improving the vibration reduction effect. By setting the fastening head 21 at the end of the fastener 20 as the installation base of the vibration absorption module 30, the overall structure is simple and compact, and occupies little space. It is not only conducive to lightweight indicators and cost control, but also facilitates the layout and installation of the powertrain in the engine compartment space.
[0048] In some embodiments, see Figures 1 to 5 The fastening head 21 includes a fastening section 211 and a screwing section 212 connected as one piece; wherein, the fastening section 211 abuts against the inner core 12, and the diameter or outer circle diameter of the screwing section 212 is smaller than the diameter or outer circle diameter of the fastening section 211; the vibration absorption module 30 is sleeved and fixed to the peripheral wall of the fastening section 211.
[0049] The function of the screwing section 212 is to install the torque wrench, so its outer circumference shape should match the torque wrench. Specifically, the outer circumference of the screwing section 212 can be square or hexagonal, or it can be circular, with square or hexagonal holes on the end face that match the torque wrench. Since the fastener 20 needs to be fastened to the powertrain side before installing the vibration absorption module 30, the vibration absorption module 30 needs to be fitted onto the screwing section 212. Therefore, the diameter of the screwing section 212 (when its outer circumference is circular) or the diameter of its outer circle (when its outer circumference is non-circular, such as square or hexagonal) is set to be less than or equal to the diameter of the fastening section 211 (when its outer circumference is circular) or the diameter of its outer circle (when its outer circumference is non-circular, such as square or hexagonal), so as to facilitate the installation of the vibration absorption module 30 onto the outer circumference of the fastening section 211.
[0050] It should be noted that in this embodiment, the vibration absorption module 30 can be press-fitted onto the outer periphery of the fastening section 211, forming an interference fit between the two. In order to improve the reliability of the connection, the outer periphery of the fastening section 211 is not circular. The vibration absorption module 30 can also form a threaded fit between its central internal threaded hole and the external thread of the peripheral wall of the fastening section 211, thereby improving the ease of disassembly and assembly.
[0051] As one specific implementation of the vibration absorption module 30 described above, please refer to Figure 5The vibration absorption module 30 includes a first connecting core 31 and a first mass block 32. One end of the first connecting core 31 has a first connecting hole 311, which is sleeved and fixed to the fastening section 211. The first connecting hole 311 has an internal space to accommodate a screwing section 212. The first mass block 32 is fitted and fixed to the outer periphery of the first connecting core 31. The vibration absorption module 30 can achieve this by using the first connecting core 31 and the fastening section 211 to form a sleeved connection, and by fitting the first mass block 32 onto the first connecting core 31. This allows the first mass block 32 to adjust the overall mode of the system, eliminating or reducing vibrations at specific frequencies to avoid resonance.
[0052] Here, the first connecting hole 311 can be an internal threaded hole that engages with the external thread on the outer periphery of the fastening section 211 to achieve the screw connection and fixation of the first connecting core 31 and the fastening section 211. The first connecting hole 311 can also be a non-circular hole, which is press-fitted onto the outer periphery of the fastening section 211 to form an interference fit. After the assembly is completed, the screwing section 212 is hidden inside the first connecting hole 311, thereby improving the structural compactness. The first mass block 32 can be circular or non-circular, and its specific shape can be adapted to the target vibration damping frequency range.
[0053] Specifically, such as Figure 5 As shown, the first connecting hole 311 is screwed to the fastening section 211. The end of the first connecting core 31 facing away from the fastening section 211 is provided with a first operating head 312. A first flexible spacer sleeve 33 is provided between the first connecting core 31 and the first mass block 32. The first connecting core 31 can be screwed onto the fastening section 211 in a threaded manner by screwing the first operating head 312. The installation method is simple and reliable. The first flexible spacer sleeve 33 can be a rubber sleeve that is vulcanized and fixed between the outer periphery of the first connecting core 31 and the first mass block 32. By setting the first flexible spacer sleeve 33 between the first connecting core 31 and the first mass block 32, the flexible buffering effect of the first flexible spacer sleeve 33 can absorb and attenuate vibration energy, reduce the vibration amplitude, and thus improve the vibration reduction effect.
[0054] Specifically, the outer circumferential shape of the first operating head 312 is consistent with that of the screwing section 212. The first operating head 312 can be square or hexagonal, consistent with the outer circumferential shape of the screwing section 212. The same torque wrench can be used to apply torque to the screwing section 212 and the first operating head 312, thereby improving the convenience of installation.
[0055] As a modified embodiment of the vibration absorption module 30 described above, please refer to Figure 6The fastening head 21 has a second connecting hole 213 at the center of the end face away from the inner core 12. The vibration absorption module 30 includes a second connecting core 34 and a second mass block 35. One end of the second connecting core 34 is connected to the second connecting hole 213, and the second mass block 35 is fitted around the outer periphery of the second connecting core 34.
[0056] By providing a second connecting hole 213 on the end face of the fastening head 21 to form an interlocking fit with the second connecting core 34, the outer periphery of the fastening head 21 can be exposed. This allows the installation of the vibration-absorbing module 30 to be free from the constraints of whether the fasteners 20 and the powertrain side are fastened, thereby improving assembly flexibility. By fitting a second mass block 35 on the second connecting core 34, the overall mode of the system can be adjusted to eliminate or weaken vibrations at specific frequencies to avoid resonance.
[0057] It should be noted that the second connecting hole 213 can be an internal threaded hole that forms a threaded fit with the external thread on the connecting post 341 for fixation, or the second connecting hole 213 can be a non-circular hole that forms an interference fit with the second connecting core 34 by press fitting to achieve fixation; the second mass block 35 can be circular or non-circular, and the specific shape can be adapted to the target vibration damping frequency range.
[0058] Specifically, such as Figure 6 As shown, the second connecting core 34 includes a connecting post 341, an intermediate post 342, and a second operating head 343 connected in sequence. The connecting post 341 is threadedly connected to the second connecting hole 213. A second flexible spacer 36 is sleeved around the outer periphery of the intermediate post 342, and a second mass block 35 is sleeved around the outer periphery of the second flexible spacer 36. The second operating head 343 has the same outer periphery shape as the fastening head 21. The second connecting core 34 adopts a three-section structure. The second operating head 343 and the fastening head 21 can apply torque using the same torque wrench, facilitating assembly. By screwing the second operating head 343, the connecting post 341 can be threaded into the second connecting hole 213, making installation simple and reliable. The second flexible spacer 36 can specifically be a vulcanized rubber sleeve fixed between the intermediate post 342 and the second mass block 35. The second flexible spacer 36 forms a flexible buffer between the second mass block 35 and the intermediate post 342, thereby absorbing and attenuating vibration energy, reducing vibration amplitude, and improving vibration reduction effect.
[0059] As another variation of the vibration-absorbing module 30 described above, please refer to... Figure 7 The fastening head 21 has an extension post 214 on the side opposite to the inner core 12. The vibration absorption module 30 includes a core sleeve 37 and a third mass block 38. The core sleeve 37 is sleeved and fixed to the extension post 214, and the third mass block 38 is sleeved on the outer periphery of the core sleeve 37.
[0060] By setting the extension post 214 to interlock with the core sleeve 37 to connect the vibration absorption module 30, the outer periphery of the fastening head 21 is exposed, thus freeing the installation of the vibration absorption module 30 from the constraints of whether the fastener 20 and the powertrain side have been connected, thereby improving assembly flexibility. Furthermore, it can further simplify the structure of the vibration absorption module 30, improve structural compactness and connection reliability. The third mass block 38, which is fitted around the core sleeve 37, is used to adjust the overall mode of the system, eliminating or weakening vibrations at specific frequencies to avoid resonance.
[0061] In this embodiment, the outer extension post 214 can be fixed by forming a threaded engagement between the outer periphery of the outer thread and the inner thread of the inner hole wall of the core sleeve 37. Alternatively, the outer extension post 214 can be fixed by forming an interference fit between a non-circular post and the core sleeve 37 through press fitting. The third mass block 38 can be circular or non-circular, and its specific shape can be adapted to the target vibration damping frequency range.
[0062] like Figure 7 As shown, the outer periphery of the core sleeve 37 is consistent with the outer periphery of the fastening head 21, and a third flexible spacer 39 is fitted around the outer periphery of the core sleeve 37. The third mass block 38 is fitted around the outer periphery of the third flexible spacer 39. Since the outer periphery of the core sleeve 37 is consistent with the outer periphery of the fastening head 21, the same torque wrench can be used to apply torque to the fastening head 21 and the core sleeve 37, thereby meeting the threaded connection assembly requirements between the fastener 20 and the powertrain side, and between the core sleeve 37 and the fastening head 21, improving the convenience of assembly operations. Specifically, the third flexible spacer 39 can be a rubber sleeve that is vulcanized and fixed between the outer periphery of the core sleeve 37 and the third mass block 38. The third flexible spacer 39 can form a flexible buffer between the third mass block 38 and the core sleeve 37, thereby absorbing and attenuating vibration energy, reducing vibration amplitude, and improving vibration reduction effect.
[0063] It should be noted that you should refer to [link / reference]. Figure 8 The end of the aforementioned core sleeve 37 facing away from the fastening head 21 is closed to form a third operating head 371, and the outer circumferential shape of the third operating head 371 is consistent with that of the fastening head 21. By setting the third operating head 371 at the end of the core sleeve 37, the third operating head 371 can, on the one hand, close the port of the core sleeve 37, improving the structural strength of the core sleeve 37, and on the other hand, apply torque to the third operating head 371 using a torque wrench adapted to the fastening head 21, thereby screwing the core sleeve 37 onto the fastening head 21, making the operation simple and convenient.
[0064] Based on the same inventive concept, combined with Figures 1 to 8 It is understood that this application also provides a vehicle including the above-described suspension shock absorber.
[0065] Compared with the prior art, the vehicle provided by this utility model adopts the above-mentioned suspension vibration absorber. It is connected to the frame side or subframe side through the outer frame 11. One end of the fastener 20 passes through the inner core 12 and is connected to the powertrain side to connect the inner core 12 to the powertrain side. The rubber main spring 13 between the outer frame 11 and the inner core 12 absorbs vibration. On this basis, the fastening head 21 formed by the end of the fastener 20 away from the inner core 12 is connected to the vibration absorption module 30. The vibration absorption module 30 absorbs and attenuates the vibration of the suspension body 10, thereby achieving frequency avoidance and improving the vibration reduction effect. By setting the fastening head 21 at the end of the fastener 20 as the installation base of the vibration absorption module 30, the overall structure is simple and compact, and occupies little space. It is not only conducive to lightweight indicators and cost control, but also facilitates the layout and installation of the powertrain in the engine compartment space.
