Description

Technical Field

[0001] The utility model relates to the technical field of automobile and parts manufacturing, in particular to a magnetic ring resonance block. Background Art

[0002] With the advancement of technology, more and more PHEV (plug-in hybrid electric vehicles) models are now on the market. People have higher and higher requirements for vehicles, requiring better NVH (noise, vibration and harshness) performance. More and more vehicles are adding resonant blocks on their half-axles to optimize NVH performance. At the same time, with the popularity of PHEV models, more and more hybrid transmissions are being introduced to the market, bringing stronger performance and more fuel-efficient effects. When the hybrid transmission works in pure electric mode, the PCM (power control module) will generate high-frequency IGBT (insulated gate bipolar transistor) switching harmonics. The high-frequency harmonic components generated by the IGBT switch generate shaft voltages on the stator and rotor, and the shaft voltage generates shaft currents, forming common-mode electromagnetic emissions that are radiated through the half-axles (antenna effect).

The above-mentioned resonant block assembly integrates the mass component and the electromagnetic conversion component together in the flexible sleeve, and the flexible sleeve is used to be installed on the drive shaft of the chassis of the whole vehicle. The electromagnetic conversion component can convert the radiated electromagnetic energy into heat energy or other forms of energy through the electromagnetic effect to reduce the electromagnetic radiation of the whole vehicle. The resonant block assembly provided in this embodiment can both optimize the NVH performance and reduce electromagnetic radiation, thereby optimizing the performance of the vehicle.

[0004] However, the above device still has the following problems during implementation:

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-9 , the utility model provides a technical solution:

[0034] A magnetic ring resonance block comprises a sleeve 1 of a vulcanized rubber structure, wherein a magnetic ring 9 and a counterweight ring 10 are respectively arranged in the sleeve 1, and a through hole 8 is provided in the sleeve 1, wherein a magnetic end 4 and a counterweight end 5 for embedding the magnetic ring 9 and the counterweight ring 10 are provided in the sleeve 1, and a connecting section 7 is provided between the magnetic end 4 and the counterweight end 5, and the connecting section 7 is used to adjust the distance between the magnetic end 4 and the counterweight end 5;

[0035] In this embodiment, the connecting section 7 is used to connect the magnetic end 4 and the counterweight end 5, so that the distance between the magnetic end 4 and the counterweight end 5 can be adjusted, and the outer size of the sleeve 1 and the length of the sleeve 1 can be changed, so as to adapt to automobile half-axles of different shaft sections.

[0036] It should be noted that the vulcanized rubber structure adopted by the sleeve 1 makes the sleeve 1 a flexible structure, which is convenient for wrapping the magnetic ring 9 and the counterweight ring 10. At the same time, the magnetic ring 9 and the magnetic end 4 are both configured as annular structures with simple and regular structures, which are convenient for processing and installation and use.

[0037] It should be noted that a magnetic ring 9 is arranged in the sleeve 1, and the radiated electromagnetic energy is converted into heat energy or other forms of energy through the electromagnetic effect, so as to reduce the electromagnetic radiation of the whole vehicle and meet the EMC electromagnetic compatibility requirements; since the dead weight of the magnetic ring 9 itself will affect the resonance block, a counterweight ring 10 is provided for mass balance. When conducting production tests, it is necessary to adjust the mass of the counterweight ring 10 to obtain the frequency of the magnetic ring resonance block to avoid resonance between the vehicle half-axle and the whole vehicle, and meet the NVH requirements through frequency modulation.

[0038] The counterweight ring 10 is configured as a hollow ring structure, and a plurality of groups of glue injection holes 6 are opened on one side of the counterweight ring 10 .

[0039] In this embodiment, the counterweight ring 10 is set as a hollow ring structure, and a plurality of groups of glue injection holes 6 are opened on one side of the counterweight ring 10. A certain mass of glue can be injected into the interior of the counterweight ring 10 at any time, and the mass of the counterweight ring 10 can be adjusted at any time without disassembling the resonance block or other components. The overall mass of the resonance block can be adjusted in time to ensure the application requirements of the resonance block.

[0040] The through hole 8 , the magnetic ring 9 and the counterweight ring 10 are arranged in a concentric structure, and the through hole 8 passes through the magnetic end 4 , the connecting section 7 and the counterweight end 5 in sequence.

[0041] In this embodiment, a magnetic ring resonance block provided by the utility model integrates a sleeve 1, a counterweight ring 10 and a magnetic ring 9. The magnetic ring 9 and the counterweight ring 10 are wrapped in the sleeve 1 of the vulcanized rubber structure. At the same time, the magnetic end 4, the connecting section 7 and the counterweight end 5 are coaxially arranged, and the entire magnetic ring resonance block is used to be installed on the surface of the automobile half-axle.

[0042] The connecting section 7 includes an insert ring 14 and a connecting ring 15. The insert ring 14 is fixedly connected to the side of the outer side of the magnetic end 4 close to the counterweight end 5, and the connecting ring 15 is fixedly connected to the side of the outer side of the counterweight end 5 close to the magnetic end 4. A slot is provided in the connecting ring 15, and the insert ring 14 is inserted into the slot.

[0043] In this embodiment, a connecting section 7 is provided between the magnetic end 4 and the counterweight end 5, and the magnetic end 4 and the counterweight end 5 are connected by means of the plug-in structure of the plug ring 14 and the connecting ring 15, so as to facilitate adjustment of the distance between the magnetic end 4 and the counterweight end 5, change the length of the entire resonance block, and adapt to different installation shaft sections of the automobile half-axle.

[0044] It should be noted that by pulling the magnetic end 4 or the counterweight end 5, the insert ring 14 will slide in the slot of the connecting ring 15, thereby changing the annular width of the connecting section 7 to achieve adjustment, see Figure 8 and Fig. 9 In the initial state of the sleeve 1, the width of the connecting section 7 is H1. When stretched to the limit position, the width of the connecting section 7 is H2. Therefore, the adjustment range of the length X of the sleeve (1) is: H1≥X≥H2.

[0045] There is an adjustment component in a circular equidistant array on the side of the counterweight end 5 close to the magnetic end 4, and the adjustment component includes a group of adjustment screws 3 and several groups of guide rods 2. The magnetic end 4 is provided with through holes and threaded holes that match the guide rods 2 and the adjustment screws 3 respectively. One end of the guide rods 2 and the adjustment screws 3 are rotatably connected to the outer wall of the counterweight end 5.

[0046] In this embodiment, an adjustment component is arranged between the magnetic end 4 and the counterweight end 5, and the adjustment component includes a guide rod 2 and an adjustment screw 3. The guide rod 2 and one end of the adjustment screw 3 are rotatably connected to the outer side of the counterweight end 5. During specific adjustment, only the adjustment screw 3 needs to be rotated. With the threaded connection structure of the adjustment screw 3 and the magnetic end 4, the adjustment screw 3 will push the counterweight end 5 and move away from the magnetic end 4. At the same time, several groups of guide rods 2 in a circular array with the adjustment screw 3 can ensure parallel movement between the counterweight end 5 and the magnetic end 4. That is, when the sleeve 1 is sleeved on the surface of the automobile half-axle, the movement of the counterweight end 5 increases the distance between the plug ring 14 and the connecting ring 15, thereby realizing the adjustment of the length of the sleeve 1.

[0047] The center line of the pitch circle of the adjusting component and the center line of the through hole 8 are collinear, and the radius of the pitch circle of the adjusting component is greater than the radius of the magnetic ring 9 .

[0048] In this embodiment, the opening positions of the guide rod 2 and the adjusting screw 3 are limited to be colinear with the opening center line of the through hole 8, so that the length of the sleeve 1 can be adjusted while ensuring that the magnetic end 4 and the counterweight end 5 are concentric with the automobile half-axle, ensuring the coaxiality of the resonance block and the automobile half-axle during use, and ensuring the effect of the resonance block.

[0049] It should be noted that the pitch circle radius of the limiting adjustment component is larger than the radius of the magnetic ring 9 to avoid interference between the guide rod 2 and the adjustment screw 3 and the magnetic ring 9, thereby ensuring the normal function of the resonance block.

[0050] A limiting groove 11 for limiting the installation position of the sleeve 1 is formed on the outer wall of one end of the sleeve 1 away from the counterweight end 5 .

[0051] In this embodiment, the limiting groove 11 is a clamp groove, and the magnetic ring resonant block is positioned in the axial direction at the installation position by the clamp cooperating with the clamp groove, and the clamp is clamped to fix the resonant block assembly on the surface of the automobile half shaft.

[0052] A magnetic ring mounting groove 12 is provided in the magnetic end 4 , and a counterweight ring mounting groove 13 is provided in the counterweight end 5 .

[0053] In this embodiment, a magnetic ring mounting groove 12 and a magnetic ring 9 embedded in the magnetic ring mounting groove 12 are provided in the magnetic end 4, and a counterweight ring mounting groove 13 and a counterweight ring 10 embedded in the counterweight ring mounting groove 13 are provided in the counterweight end 5. The magnetic ring 9 is capable of converting electromagnetic energy into other forms of energy. The magnetic ring mounting groove 12 and the counterweight ring mounting groove 13 are separately provided to avoid the magnetic ring 9 and the counterweight ring 10 embedded in the sleeve 1 from directly contacting the vehicle half-axle, thereby preventing the magnetic ring from breaking due to stress during movement, which can not only optimize the NVH performance but also effectively suppress the electromagnetic interference signal.

[0054] Embodiment 2:

[0055] Based on the first embodiment, the weight ring 10 is a hollow ring structure, and the mass of the weight ring 10 is adjusted by injecting glue into the inside. However, if the cavity is opened as an integral body, when the injection hole is blocked by the glue, it is impossible to continue to increase the mass of the weight ring 10 to complete the mass adjustment of the resonance block. Therefore, the following structure is set in this embodiment to prevent the above situation from happening, specifically:

[0056] There are a plurality of groups of partition plates 17 in an annular equidistant array inside the counterweight ring 10 , and a cavity 16 is formed between two adjacent groups of partition plates 17 . The glue injection holes 6 and the cavities 16 are matched and arranged.

[0057] It should be noted that when designing the counterweight ring 10, a smaller value of the design range is selected for the counterweight mass. The mass of the counterweight ring 10 is increased through the process of glue injection, thereby achieving mass adjustment of the counterweight ring 10, thereby adjusting the mass of the resonance block and improving the versatility of the resonance block.

[0058] It should be noted that, for devices or equipment that can be implemented by existing technologies, their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
