Description

Technical Field

[0001] This invention belongs to the field of automotive parts, and particularly relates to a clamp assembly for automotive stabilizer bars and its processing method. Background Technology

[0002] A car stabilizer bar typically has an exhaust pipe on its side, and the stabilizer bar is fixed to the vehicle body by a clamp. A rubber component, such as a rubber piece, is placed between the clamp and the stabilizer bar. For example, the stabilizer bar clamp disclosed in existing patent CN221476633U includes a U-shaped clamp body and a connecting plate. Both ends of the clamp body have outwardly bent portions. The connecting plate is located below the bent portions, and adjusting blocks are provided between the two ends of the connecting plate and the bent portions. The upper end of the connecting plate has a protruding connecting portion, the upper end of which is an inclined surface one. The lower end of the adjusting block is an inclined surface two that matches the inclined surface one, with the inclined surface one abutting against the inclined surface two. A through-hole is provided in the middle of the adjusting block. Screws pass through the connecting plate, the bent portions, and the adjusting block, and the screws pass through the through-hole. This adjustable car stabilizer bar clamp has the advantages of height adjustment, convenient installation, and wide applicability.

[0003] While the above solution has the advantages mentioned above, the clamps used in this solution are insufficient to block the heat emitted from the exhaust pipe. This heat can affect the lifespan of rubber components such as the clamps and stabilizer bar, impact the stability of the stabilizer bar, and increase subsequent maintenance costs.

[0004] Secondly, the above scheme uses two fixed positions for fixation, and the stability of the fixation needs to be further improved. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a clamp assembly for an automotive stabilizer bar and its processing method.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions: A clamp assembly for an automotive stabilizer bar includes a clamp body with a U-shaped portion. A U-shaped groove is provided on the inner surface of the U-shaped portion, and a U-shaped protrusion corresponding to the U-shaped groove is formed on the outer surface of the U-shaped portion. First fixing positions are provided at both ends of the clamp body. The automotive stabilizer bar clamp assembly further includes a heat dissipation reinforcement plate and a heat insulation protective plate. The heat dissipation reinforcement plate has at least a portion that conforms to the U-shaped protrusion. The U-shaped protrusion and the conforming portion are fixedly connected, forming a heat dissipation channel communicating with the outside. At least a portion of the heat insulation protective plate and at least a portion of the heat dissipation reinforcement plate form a heat insulation channel. The remaining at least a portion of the heat insulation protective plate and the U-shaped portion form a heat insulation space that communicates with the outside of the heat insulation channel. The heat dissipation reinforcement plate and the heat insulation protective plate each have a plurality of second fixing positions that are staggered from the first fixing positions.

[0007] Furthermore, along the length of the clamp body, both ends of the heat dissipation channel are connected to the outside; along the width of the clamp body, there are two heat insulation spaces and the heat insulation channel connects the two heat insulation spaces.

[0008] Furthermore, along the length direction of the contoured portion, the contoured portion has connecting grooves at both ends that are respectively connected to the outside world, and the heat dissipation channel is formed between the connecting grooves and the U-shaped protrusion.

[0009] Furthermore, along the length direction of the contoured portion, each side of the contoured portion has a first folded edge portion that bends toward the U-shaped protrusion, and a communicating groove is formed between the two first folded edges portions, wherein the first folded edges portion and the U-shaped protrusion are fixedly connected.

[0010] Furthermore, each end of the contoured portion has a widened end extending in the width direction of the clamp body, the projection of the widened end on the clamp body at least covers the first fixing position, and a flared groove communicating with the communicating groove is provided on the side of the widened end near the U-shaped protrusion.

[0011] Furthermore, the second fixing position includes two provided on one of the widened ends, one provided on the other widened end, and three provided on the heat insulation plate; the three second fixing positions provided on the widened end are triangularly distributed, and the three second fixing positions provided on the heat insulation plate are also triangularly distributed, and the second fixing positions provided on the widened end and the second fixing positions provided on the heat insulation plate are in one-to-one correspondence and connected. At least a portion of the widened end is connected to a second folded portion that is connected to the first folded portion and forms the flared groove.

[0012] Furthermore, in the width direction of the clamp body, the width of the heat insulation plate is greater than the width of the clamp body, and the width of the arched part of the heat insulation plate is greater than the width of the contoured part. The heat insulation channel and the heat insulation space are formed between the arched portion and the contoured portion, and between the arched portion and the U-shaped portion, in the width direction of the clamp body.

[0013] As one application, this application also provides a method for processing a clamp assembly for an automotive stabilizer bar, comprising the following steps: S1. The clamp body, the heat dissipation reinforcement plate and the heat insulation protection plate are obtained by stamping. S2. Fix the clamp body in S1, and move the heat dissipation reinforcement plate to a predetermined position outside the U-shaped part of the clamp body. Then, make the contoured part of the heat dissipation reinforcement plate contact the U-shaped protrusion of the U-shaped part, and weld the U-shaped protrusion and the contoured part together, and form the heat dissipation channel between the U-shaped protrusion and the contoured part. S3. Move the heat insulation plate in S1 to a predetermined position outside the heat dissipation reinforcement piece in S2, and use several fasteners to pass through the second fixing position of the heat dissipation reinforcement piece and the heat insulation plate, so that at least a portion of the heat insulation plate and at least a portion of the heat dissipation reinforcement piece form a heat insulation channel, and the remaining at least a portion of the heat insulation plate and the U-shaped part form a heat insulation space that allows the heat insulation channel to communicate with the outside, thus obtaining the clamp assembly for the car stabilizer bar.

[0014] As one application, this application also provides a method for processing a clamp assembly for an automotive stabilizer bar, comprising the following steps: S1. The clamp body, the heat dissipation reinforcement plate and the heat insulation protection plate are obtained by stamping. S2. Fix the clamp body in S1, and pre-connect the heat dissipation reinforcement plate and the heat insulation protection plate together with several fasteners, and make the contoured part of the heat dissipation reinforcement plate contact the U-shaped protrusion of the clamp body with the fasteners, and weld the U-shaped protrusion and the contoured part together to obtain the clamp assembly for automobile stabilizer bar.

[0015] Furthermore, the heat dissipation reinforcement sheet includes the following processing steps: S10. Straight sheets of reinforced sheet raw material are obtained by stamping. S11. The straight sheet of reinforcing sheet material in S10 is folded to obtain a straight sheet of reinforcing sheet material with folded edges; S12. The straight sheet of the reinforcing sheet material with folded edges in S11 is formed and processed to obtain the heat dissipation reinforcing sheet with the contoured part. S13. Punch holes in the heat dissipation reinforcement plate in S12 at the punching station to obtain a number of second fixed positions on the heat dissipation reinforcement plate, thereby obtaining the heat dissipation reinforcement plate.

[0016] Compared with existing technologies, the advantages of this application are as follows: by integrating heat dissipation reinforcement plates and heat insulation protection plates into the clamp body, a dual advantage of heat insulation and heat dissipation is constructed, which effectively blocks the heat radiation of the exhaust pipe and can quickly dissipate the heat absorbed by the heat dissipation reinforcement plates and heat insulation protection plates, significantly delaying the aging of rubber parts, ensuring the long-term stability of the stabilizer bar, and reducing maintenance costs; at the same time, through the fixed connection structure of the clamp body, heat dissipation reinforcement plates and heat insulation protection plates, the rigidity of the clamp body is greatly enhanced, and the anti-vibration and anti-loosening effect is better.

[0023] Example 1

[0024] like Figure 1 and Figure 2As shown, a car stabilizer bar clamp assembly is mainly used for the installation and fixing of stabilizer bars near the exhaust pipe of a car. In this embodiment, the raw materials of all the components are commercially available materials. In this application, the raw material is hot-rolled steel plate for automotive structure. The car stabilizer bar clamp assembly includes a clamp body 1 formed by stamping and having an arched U-shaped part 14. The inner side of the U-shaped part 14 forms an arc-shaped mounting cavity for accommodating the car stabilizer bar and matching rubber parts. At both ends of the clamp body 1, clamp mounting parts extending radially outward are symmetrically arranged. The bottom surface of the clamp mounting part is a flat contact surface that can fit with the mounting surface. Each clamp mounting part has a through first fixing position 13. During installation, the entire clamp assembly can be locked onto the car frame or subframe by passing a bolt through the first fixing position 13. The installation is convenient and the fixing is firm. When it is necessary to replace the stabilizer bar or rubber parts, the parts to be replaced can be removed by loosening the bolt. Of course, in order to facilitate connection and fixation, a nut is provided on the first fixing position 13, and the nut is directly welded to the clamp body 1. This method can enhance the structural strength of both ends of the clamp body 1, and at the same time facilitate disassembly and assembly.

[0025] Specifically, the circumferential region at the center of the U-shaped section 14 is integrally stamped with a radially outward protruding arched structure, such as... Figure 4 and Figure 5 As shown, a U-shaped groove 11 is provided on the inner surface of the U-shaped portion 14. The U-shaped groove 11 is used to accommodate and limit the matching rubber part of the stabilizer rod. During installation, the rubber part can be quickly positioned and limited to prevent axial movement of the rubber part. A U-shaped protrusion 12 corresponding to the U-shaped groove 11 is formed on the outer surface of the U-shaped portion 14. In this embodiment, as shown... Figure 5 The U-shaped groove 11 and U-shaped protrusion 12 shown are coaxially arranged to ensure that the wall thickness of the arched structure is uniform and that the structure is subjected to uniform stress, so as to avoid the problem of eccentric load deformation.

[0026] Furthermore, regarding the aforementioned U-shaped protrusion 12, a heat dissipation reinforcement plate 2 for heat insulation and heat dissipation is welded and fixed to the outer surface of the U-shaped protrusion 12 of the U-shaped portion 14, such as... Figures 3-5 As shown, the middle part of the heat dissipation reinforcement plate 2 is a contoured part 23 that matches the arched contour area of ​​the U-shaped part 14. The U-shaped protrusion 12 and the contoured part 23 are fixedly connected and form a heat dissipation channel P1 that connects to the outside world between them. Specifically, along the length of the contoured portion 23 (which can also be understood as the circumferential direction), the contoured portion 23 has connecting grooves 21 at both ends that are connected to the outside. Secondly, along the length of the contoured portion 23, each side of the contoured portion 23 has a first folded edge 230 bent towards the U-shaped protrusion 12, and a connecting groove 21 is formed between the two first folded edges 230. The connecting groove 21 and the first folded edges 230 are integrally stamped onto the heat dissipation reinforcement plate 2. The first folded edges 230 are welded to the outer surface edges of the U-shaped protrusion 12. After welding, the inner wall of the connecting groove 21 is spaced apart from the top surface of the U-shaped protrusion 12, forming a heat dissipation channel P1 that runs circumferentially along the clamp body 1 and is open at both ends to the outside. Simultaneously, at both ends of the contoured portion 23 along the length direction, there are widened ends 25 extending in the width direction of the clamp body 1. At least a portion of the sides of the widened ends 25 are connected to... Figure 6 The second folded edge 231 shown is connected to the first folded edge 230 and forms a flared groove 22. The second folded edge 231 not only serves as a component of the flared groove 22, but also enhances the torsional strength of the heat dissipation reinforcement plate 2.

[0027] The widened end 25 can further increase the area to a certain extent, thereby blocking heat and strengthening the structure of the contoured part 23.

[0028] Secondly, the projection of the widened end 25 onto the clamp body 1 at least covers the first fixing position 13, which serves to initially block the high-temperature radiation from the exhaust pipe to the first fixing position 13. Furthermore, the widened end 25 near the U-shaped protrusion 12 and both ends of the circumferential heat dissipation channel P1 are provided with... Figure 6 The flared groove 22 shown has an opening area that gradually increases in size along the direction away from the inner cavity of the heat dissipation channel P1. Its advantages are: when the vehicle is in motion, the flared groove 22 on the windward side can guide more airflow smoothly into the heat dissipation channel P1, significantly improving heat removal efficiency; or when the vehicle is idling, the hot air inside the heat dissipation channel P1 can also smoothly rise and be discharged through the flared groove 22, without airflow obstruction or heat accumulation. Simultaneously, the circumferential penetration range of the heat dissipation channel P1 is greater than the radial width of the clamp body 1, completely covering the entire outer surface of the arched structure, eliminating heat dissipation dead zones. The heat absorbed by the structure can be quickly removed by the airflow within the heat dissipation channel P1, avoiding aging of rubber parts due to high temperatures.

[0029] In addition, the heat dissipation reinforcement plate 2 is welded to the U-shaped protrusion 12 on both sides of the U-shape, which is equivalent to adding an integrated reinforcement structure to the top of the U-shaped part 14. This can greatly improve the bending and fatigue resistance of the clamp body 1. When the vehicle is driving on bumpy roads for a long time, it can effectively prevent the arched structure from deforming and greatly extend the service life of the component.

[0030] Furthermore, such as Figure 1 and Figure 2 As shown, the heat dissipation reinforcement plate 2 is located away from the top of the clamp body 1 and is fixedly connected to the heat insulation protection plate 3, which enhances the heat insulation effect, by fasteners 4. Similarly, the middle part of the heat insulation protection plate 3 is an arched plate similar to the arched contour area of ​​the clamp body 1. Specifically, the heat dissipation reinforcement plate 2 and the heat insulation protection plate 3 each have several second fixing positions 24 that are staggered from the first fixing position 13. The second fixing positions 24 are respectively locked and fixed by fasteners 4 (hexagonal bolts and lock nuts). The second fixing positions 24 include two on one of the widened ends 25, one on the other widened end 25, and three on the heat insulation protection plate 3. The heat insulation protection plate 3 has a fixing position opening 32, and the second fixing positions 24 are distributed in the fixing position opening 32. After assembly, the fixing position opening 32 fits snugly against the widened end. 25; The three second fixing positions 24 on the widened end 25 are triangularly distributed, and the three second fixing positions 24 on the heat insulation plate 3 are also triangularly distributed. The second fixing positions 24 on the widened end 25 and the second fixing positions 24 on the heat insulation plate 3 are in one-to-one correspondence and connected. The asymmetrical triangular arrangement has the effect of preventing errors during batch assembly, avoiding the problem of the heat insulation plate being installed backwards or off-center, and greatly improving the assembly efficiency of the production line. At the same time, the triangularly distributed locking points can form an anti-loosening effect under the continuous vibration of the vehicle. Compared with double-point locking, there will be no situation where two bolts loosen simultaneously. Even if one locking point has a slight decrease in preload, the other two points can still ensure the stability of the connection, effectively avoiding the abnormal noise and heat insulation failure caused by the loosening of the heat insulation plate 3. From the perspective of fixing positions of the heat dissipation reinforcement plate 2 and the clamp body 1, there are two second fixing positions 24 at one end of the heat dissipation reinforcement plate 2 combined with a first fixing position 13 at one end of the clamp body 1. At this time, the two second fixing positions 24 and the first fixing position 13 form a triangular distribution. Meanwhile, a second fixing position 24 at the other end of the heat dissipation reinforcement plate 2 and another first fixing position 13 at the other end of the clamp body 1 are staggered. The above structure can provide a very good installation and fixing structure in both top and side views.

[0031] Furthermore, the use of detachable fasteners 4 makes maintenance more convenient compared to welding. The heat insulation plate 3 can be directly removed, and different specifications of heat insulation plates can be quickly replaced according to the thermal environment of different vehicle models, offering greater adaptability. Fasteners 4 include bolts, etc. Of course, adding anti-loosening washers to the bolts can prevent loosening.

[0032] After the heat insulation plate 3 and the heat dissipation reinforcement plate 2 are locked and fixed, the heat insulation plate 3 has an arched part 31 in the middle, and the arched part 31 and the contoured part 23 maintain a preset interval space. Specifically, the arc size of the arched part 31 is larger than the arc size of the contoured part 23, that is, the radii of the two are different. The interval cavity between the middle area of ​​the arched part 31 and the contoured part 23 forms a... Figures 2-5 The diagram shows a heat insulation channel P2 that runs axially through the clamp body 1 and is open at both ends. Furthermore, in the width direction of the clamp body 1, the width of the heat insulation protective plate 3 is greater than the width of the U-shaped portion 14, directly blocking the hot airflow from the exhaust pipe from directly affecting the clamp body 1 and the rubber component area, achieving efficient passive heat insulation and improving the component's protective performance. In the width direction of the clamp body 1, the two sides of the arched portion 31 of the heat insulation protective plate 3 and the U-shaped portion 14 form two heat insulation spaces P3 that connect the heat insulation channel P2 to the outside. The heat insulation channel P2 connects the two heat insulation spaces P3. In this connected cavity structure, any unblocked residual heat will enter the heat insulation channel P2 and the heat insulation spaces P3 on both sides, and be quickly discharged through the axial or lateral openings.

[0033] In this embodiment, the clamp body 1 serves as the main body and forms a fixation for the vehicle stabilizer bar. The clamp body 1 is further configured with a heat dissipation reinforcement plate 2 and a heat insulation protection plate 3. From the perspective of heat insulation and heat dissipation, the heat insulation protection plate 3 with its increased area can effectively block heat emitted from sources such as exhaust pipes. Secondly, the heat dissipation channel P1 formed between the clamp body 1 and the heat dissipation reinforcement plate 2 can play multiple roles of heat insulation and heat dissipation because air has very poor thermal conductivity. Furthermore, from the perspective of structural strength, by adding the heat dissipation reinforcement plate 2 and the heat insulation protection plate 3 to the outer surface of the clamp body 1, a radial structure and width direction reinforcement can be formed on the top of the arched area of ​​the clamp body 1.

[0034] Secondly, the heat insulation plate 3 provided on the heat dissipation reinforcement plate 2 further increases the heat insulation area. At least in this embodiment, the heat insulation plate 3 can completely cover the clamp body 1, forming a heat insulation technology with a large outer area. Furthermore, the heat insulation plate 3 and the heat dissipation reinforcement plate 2 are synchronously fixed by fasteners 4, which can strengthen the structure of the heat dissipation reinforcement plate 2 to prevent deformation caused by heat at the position where the fasteners 4 are inserted. Combined with the second folded edge 231 on the widened end 25, it can significantly improve the deformation resistance performance of the widened end 25 in the thickness direction.

[0035] Example 2

[0036] Based on the first embodiment of the automobile stabilizer bar clamp assembly, this embodiment describes a processing method for an automobile stabilizer bar clamp assembly.

[0037] The processing method specifically includes the following steps: S1. The clamp body 1, heat dissipation reinforcement plate 2, and heat insulation protection plate 3 are obtained by stamping. According to the design dimensions of the clamp body 1, heat dissipation reinforcement plate 2, and heat insulation protection plate 3, the clamp body 1, heat dissipation reinforcement plate 2, and heat insulation protection plate 3 are stamped from automotive structural hot-rolled steel plates that meet the requirements. The fixing installation parts at both ends of the clamp body 1 and the arched structure in the axial middle are stamped out simultaneously, and the corresponding fixing positions, such as fixing holes, are stamped at both ends of the heat dissipation reinforcement plate 2 and the heat insulation protection plate 3. Stamping can ensure high consistency of the dimensions of each component and uniform structural strength, which is conducive to improving the efficiency of mass production and the product qualification rate.

[0038] Specifically, such as Figures 8-11 As shown, the processing steps for the heat dissipation reinforcement plate 2 are as follows: S10. The hot-rolled steel sheet used for automotive structures is obtained as a straight sheet of reinforcing material through stamping. S11. The reinforcing sheet (hot-rolled steel plate straight sheet) in the first step is folded to obtain a reinforcing sheet (hot-rolled steel plate straight sheet) with folded edges. The first folded edge 230 is formed simultaneously on the circumferential edge of the reinforcing sheet (hot-rolled steel plate straight sheet) to ensure that the folded edge can be seamlessly fitted with the circumferential edge of the U-shaped protrusion 12 of the clamp body after folding. At the same time, the folded edge adopts a rounded corner transition design to avoid stress concentration and cracking of the plate. The connecting groove 21 structure is formed simultaneously. S12. The reinforcing sheet (hot-rolled steel plate straight sheet) with folded edge in the second step is formed and processed. The reinforcing sheet (hot-rolled steel plate straight sheet) with folded edge is integrally formed into a contour part 23 that is completely adapted to the U-shaped protrusion 12 of the clamp body 1. During the forming process, the stamping stroke and pressure are strictly controlled to avoid deformation and warping of the formed folded edge, so as to obtain the heat dissipation reinforcing sheet 2 with contour part 23. S13. Punch holes in the heat dissipation reinforcement plate 2 from the third step at the punching station. Punch holes precisely according to the preset triangular distribution points to obtain several second fixed positions 24 on the heat dissipation reinforcement plate 2, thus obtaining the heat dissipation reinforcement plate 2.

[0039] S2. Clamp and fix the clamp body 1 onto the limiting fixture of the welding tool, and lock it completely with the positioning pin and pressure block to ensure that the clamp body 1 will not move or shift during the welding and assembly process. Then move the heat dissipation reinforcement plate 2 to the outer side of the U-shaped part 14 of the clamp body 1 and pre-position it. Fine-tune the position so that the contoured part 23 of the heat dissipation reinforcement plate 2 and the U-shaped protrusion 12 of the U-shaped part 14 are in direct contact, ensuring that the first folded edge 230 is completely attached to the outer surface of the U-shaped protrusion 12, so that the two are tightly attached. This ensures both welding strength and that the heat dissipation channel P1 formed laterally is unobstructed and does not block airflow. After the alignment is completed, weld along the first folded edge 230 to completely weld the heat dissipation reinforcement plate 2 and the U-shaped protrusion 12 into one piece, simultaneously forming a heat dissipation channel P1 that runs circumferentially along the clamp body 1. Full welding can improve the structural rigidity and enhance the clamp's resistance to deformation and vibration.

[0040] S3. Without moving the clamp body 1 of the welded heat dissipation reinforcement plate 2, move the heat insulation plate 3 to the pre-positioned outer side of the heat dissipation reinforcement plate 2 in the first step, adjust the position so that the mounting holes at both ends of the heat insulation plate 3 and the mounting holes at both ends of the heat dissipation reinforcement plate 2 are completely coaxial, ensuring smooth installation of the fasteners 4 and uniform gap of the heat insulation channel P2. After alignment, use the matching fasteners 4 to pass through the second fixing positions 24 at both ends and lock them. Multi-point locking can improve connection reliability and prevent loosening under long-term vibration. After locking, at least a part of the heat insulation plate 3 and at least a part of the heat dissipation reinforcement plate 2 form the heat insulation channel P2. The remaining at least a part of the heat insulation plate 3 and the U-shaped part 14 form the heat insulation space P3 that connects the heat insulation channel P2 with the outside, thus obtaining the clamp assembly for the automotive stabilizer bar.

[0041] Example 3

[0042] Based on Embodiment 1, this embodiment provides a method for processing a clamp assembly for an automotive stabilizer bar.

[0043] The specific processing method includes the following steps: S1. According to the design dimensions, the clamp body 1, heat dissipation reinforcement plate 2, and heat insulation protection plate 3 are stamped from automotive structural hot-rolled steel sheet that meets the requirements. The fixing and mounting parts at both ends of the clamp body, the arched structure in the axial center, and the assembly holes are pre-drilled at both ends of the heat dissipation reinforcement plate and the heat insulation protection plate. One-piece stamping ensures high dimensional consistency and uniform structural strength of all components, which is beneficial for improving mass production efficiency and product qualification rate. The processing steps for the heat dissipation reinforcement plate 2 in this embodiment are described in Embodiment Two.

[0044] S2. First, clamp the clamp body 1 onto the limiting fixture of the welding tooling, and lock it completely with the positioning pin and pressure block to ensure that the clamp body 1 will not move or shift during the entire welding and assembly process; then, use the matching fasteners 4 to pre-connect the heat dissipation reinforcement plate 2 and the heat insulation protection plate 3 together and pre-tighten the fasteners 4 so that the heat dissipation reinforcement plate 2 and the heat insulation protection plate 3 form a fixed whole in relative position. This operation can pre-lock the uniform pre-set gap in the middle of the two, accurately limit the forming size of the subsequent heat insulation channel P2, and avoid the problem of uneven gap that is easy to occur in step assembly; then, move the pre-assembled whole to directly above the clamp body 1, and fine-tune the position so that the contour part 23 of the heat dissipation reinforcement plate 2 and the clamp body 1 are aligned with the clamp body 1. The U-shaped protrusion 12 of the clamp body 1 is fully in contact with the clamp, ensuring that the contact surfaces are fully in contact. After the contact is in place, the U-shaped protrusion 12 and the contour part 23 are welded and fixed together by a full welding process. At the same time, a heat dissipation channel P1 that runs through the circumference of the clamp body 1 is formed. The pre-assembled heat dissipation reinforcement plate 2 and the heat insulation protection plate 3 can effectively suppress the welding warping and deformation of the heat dissipation reinforcement plate 2 during the welding process, ensuring the unobstructed flow and forming consistency of the heat dissipation channel P1. At this time, a heat insulation channel P2 is formed between the heat insulation protection plate 3 and the heat dissipation reinforcement plate 2. The remaining part of the heat insulation protection plate 3 and the U-shaped part 14 form a heat insulation space P3 that connects the heat insulation channel P2 with the outside world, thus obtaining the clamp assembly for the car stabilizer bar.

[0045] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
