Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a stabilizer bar heat insulation assembly. Background Technology

[0002] With the increasing development of range-extended vehicles, the addition of decorative and protective panels to the engine compartment leads to poor heat dissipation and high engine compartment temperature, which affects the thermal aging performance of rubber. As the engine compartment temperature rises, the thermal properties of the rubber deteriorate, affecting its strength and service life.

[0003] During the research, it was discovered that the stabilizer bar bushing is close to the exhaust pipe of the range extender, and the exhaust pipe temperature is as high as 120°C, which is an important heat source affecting the temperature of the stabilizer bar. At present, the rubber used in stabilizer bar bushings generally has a heat aging temperature of 70°C to 90°C. In order to reduce the impact of exhaust heat on the life of stabilizer bar bushings, it is urgent to carry out thermal protection for stabilizer bar bushings. In order to address the above issues, in-depth research was conducted, which led to this case. Summary of the Invention

[0004] This application provides a stabilizer bar heat insulation assembly, applied to a bushing of an automotive stabilizer bar. The bushing is fitted onto the stabilizer bar, and the stabilizer bar heat insulation assembly includes: A heat-insulating bracket is detachably connected to the bushing; A heat shield is installed on the heat shield bracket, and the heat shield covers at least a portion of the bushing.

[0005] The heat insulation bracket is provided with a connecting component, and the heat insulation cover is provided with a connecting hole. The connecting component passes through the connecting hole to connect the heat insulation cover and the heat insulation bracket.

[0006] The connecting hole is an oblong hole, and the length direction of the connecting hole is parallel to the axial direction of the stabilizer rod.

[0007] The connection assembly includes a connector and a connector; The connecting seat is disposed on the outer peripheral surface of the bushing; The connector is connected to the connector base through the connecting hole.

[0008] The outer circumferential surface of the bushing corresponds to the outer wall of the heat insulation bracket, and the side of the bushing away from the stabilizing rod is an open surface.

[0009] The number of connection holes is multiple, and the number of connection components corresponds one-to-one with the number and position of the connection holes.

[0010] The bushing consists of a pair of bushing sets, which are symmetrically connected and wrapped around the stabilizer bar.

[0011] The heat insulation bracket includes a main body and a pair of sides; The main body is an arched structure with a pair of open ends, and the main body is distributed along the outer peripheral surface of the bushing, with the pair of open ends extending to the open surface; The two sides are symmetrically arranged on both sides of the main body.

[0012] The junction between the side and the main body is closer to the sliding contact point than the edge of the side that is further away from the main body.

[0013] A pair of ear pieces extend symmetrically from a pair of open ends of the main body of the heat insulation bracket, and a pair of connecting holes are provided on the pair of ear pieces.

[0014] The beneficial effects of this application are as follows: the stabilizer bar heat insulation component, through its double-layer heat insulation structure and adjustable heat shield design, significantly reduces the surface temperature of the bushing, delays rubber aging, and its modular installation and detachable structure improves maintenance efficiency. The large coverage area of ​​the heat shield and its semi-enclosed structure achieve efficient heat insulation. The multi-point fixing of the connecting components ensures the stability of the heat shield, adapts to the cabin layout, extends the service life of the bushing, and has excellent overall performance. Specifically, it also has the following advantages: 1. The heat shield adopts a non-circular design to match the curvature of the stabilizing rod, forming a seamless fit. The heat shield has a large protection area and is lightweight, effectively isolating external heat, significantly reducing the working temperature of the bushing, and delaying rubber aging.

[0015] 2: The connecting seat is pre-embedded on the outer circumference of the bushing. It is connected to the connecting seat by passing through the connecting hole with a T-bolt. It is close to the outer wall of the heat shield. The connecting hole is oval so that the position of the heat shield can be adjusted. It ensures that there is no interference with other components in the cabin. Multiple sets of connecting holes are evenly distributed to avoid local stress concentration and improve installation stability.

[0016] 3: The enclosure structure of the isolation bracket provides radial support, and the rolled edges form reinforcing ribs to enhance the torsional stiffness of the isolation bracket. The isolation bracket wraps around the outer circumference of the bushing, absorbing thermal expansion through elastic deformation to prevent bushing displacement. At the same time, it reserves installation space for connecting components and ensures the flatness of the inner surface of the heat insulation cover. Attached Figure Description

[0020] With the rapid development of intelligent technology in modern automobiles, many car infotainment systems have added decorative panels, which can hinder heat dissipation in the engine compartment. The close proximity of the stabilizer bar 1 bushing 2 to the range extender exhaust pipe causes the stabilizer bar 1 bushing 2 to be severely affected by heat and age, which will affect the service life of the bushing 2.

[0021] To address the above issues, please refer to the appendix to the instruction manual. Figure 1-5 As can be seen, the present application provides a stabilizer bar heat insulation assembly, which is applied to the bushing 2 of the stabilizer bar 1 of an automobile. The stabilizer bar 1 is usually a rod with a circular cross section. There are usually a pair of mounting holes at both ends of the stabilizer bar 1. The stabilizer bar 1 can be fixed to the engine compartment by threaded rods. The bushing 2 is fitted onto the stabilizer bar 1. Thus, the stabilizer bar heat insulation assembly is installed based on the bushing 2 of the stabilizer bar 1.

[0022] Specifically, the stabilizer bar insulation assembly includes: The heat insulation bracket 3 is detachably connected to the bushing 2 and wraps around the bushing 2. The heat insulation bracket 3 and the bushing 2 are connected separately. The heat insulation bracket 3 serves as the installation base for the heat insulation cover 4. At the same time, the heat insulation bracket 3 wraps around the bushing 2 and is also wrapped with heat insulation material, which further isolates the bushing 2 from the external environment. The wrapping structure of the isolation bracket provides radial support. The side 32 is rolled to form a reinforcing rib, which improves the torsional stiffness of the isolation bracket. The wrapping heat insulation and limiting function prevent the bushing 2 from displacing due to thermal expansion.

[0023] Heat shield 4, mounted on heat shield bracket 3, covers at least part of bushing 2. (See attached instruction manual) Figure 1-5 It can be seen that the heat insulation cover 4 has an arched cross section along the radial direction of the stabilizing rod 1. The heat insulation cover 4 is the main structure that produces the working effect during the heat insulation process of the bushing 2. The heat insulation cover 4 is partially wrapped around the heat insulation bracket 3. The heat insulation cover 4 encloses the bushing 2 and the heat insulation bracket 3, thereby isolating the heat insulation cover 4 and producing a heat insulation effect, protecting the inner bushing 2 from the outside.

[0024] The heat insulation cover 4 uses heat insulation materials and has a large protective area to effectively isolate the external environment. For example, the heat insulation cover 4 can adopt a three-layer composite structure: the outer layer is an aluminum foil reflective layer that reflects more than 90% of radiant heat, the middle layer is a ceramic fiber blanket that insulates conductive heat, and the inner layer is an aluminum silicate coating to prevent heat radiation penetration. The arched design matches the curvature of the stabilizing rod 1 to ensure that it forms a seamless fit with the heat insulation bracket 3 after installation, with a large protective area.

[0025] In some embodiments of this application, the bushing 2 corresponds to the outer peripheral surface of the heat insulation bracket 3, the side of the bushing 2 away from the stabilizing rod 1 is an open surface, and the outer peripheral surface of the bushing 2 abuts against the inner surface of the heat insulation bracket 3.

[0026] In some embodiments of this application, the bushing 2 is fitted onto the stabilizer bar 1. The bushing 2 has a semi-circular radial cross section along the stabilizer bar 1. One circular end of the bushing 2 is coaxially fitted onto the stabilizer bar 1, and one rectangular end of the bushing 2 abuts against the inner wall of the cabin, providing support and ensuring the installation interval of the stabilizer bar 1. Specifically, the bushing consists of a pair of bushing kits. The pair of bushing kits are symmetrically connected and wrap around the stabilizer bar. When replacing the bushing, the connection between the pair of bushing kits is directly disconnected, making the operation convenient and simple.

[0027] Bushing 2 is made of rubber, specifically high-damping silicone rubber, and has a wide operating temperature range of -40℃ to 150℃. Refer to the instruction manual for details. Figure 1-5 It can be seen that the semi-circular cross-section design makes the bushing 2 form a stress dispersion zone when subjected to radial force. The rectangular end face forms a sealing surface with the cabin sheet metal through pre-compression deformation, effectively blocking the intrusion of water vapor and dust. At the same time, its elastic buffering characteristics can absorb the high-frequency vibration energy of the stabilizer bar 1 and extend the service life of the metal parts.

[0028] In some embodiments of this application, in order to facilitate the adaptation to the specific structure of the vehicle body and the heat insulation requirements, a connecting component 5 is provided on the heat insulation bracket 3, and a connecting hole 41 is provided on the heat insulation cover 4. The connecting component 5 passes through the connecting hole 41 to connect the heat insulation cover 4 and the heat insulation bracket 3. While fixing the heat insulation cover 4 through the connecting component 5, the position of the heat insulation cover 4 relative to the bushing 2 can be adjusted so that the heat insulation cover 4 matches the layout structure in the engine compartment and achieves a more perfect heat insulation effect.

[0029] In some embodiments of this application, the connecting hole 41 is an elongated hole, the length direction of the connecting hole 41 is parallel to the axial direction of the stabilizer rod 1, the connecting component 5 passes through the connecting hole 41, and the diameter of the minor axis of the elongated structure of the connecting hole 41 is the same as that of the connecting component 5.

[0030] In some embodiments of this application, the connecting component 5 includes a connecting seat 51 and a connecting member 52; the connecting seat 51 is disposed on the outer peripheral surface of the bushing 2; the connecting member 52 passes through the connecting hole 41 and is connected to the connecting seat 51.

[0031] In some embodiments of this application, there are multiple connection holes 41, and the number and position of the connection components 5 correspond one-to-one with the number and position of the connection holes 41. Multiple connection holes 41 cooperate with multiple connection components 5, and the heat insulation cover 4 can be stabilized and fixed to the greatest extent by multiple evenly distributed connection components 5 and connection holes 41.

[0032] In some embodiments of this application, the heat insulation bracket 3 includes a main body 31 and a pair of side edges 32. The main body 31 and the pair of side edges 32 are integrally formed. The main body 31 is an arched structure with a pair of open ends. The pair of side edges 32 are symmetrically extended from the edges of the main body 31 near the two sides. The main body 31 and the pair of side edges 32 together form an arch-shaped structure. At the same time, the pair of side edges 32 roll outward, so that the joint between the side edges 32 and the main body 31 is closer to the side edges 32 than the edges of the side edges 32 that are far away from the main body 31. This allows the pair of side edges 32 to abut against the inner surface of the isolation cover, providing support for the inner surface of the isolation cover. At the same time, it also makes the main body 31 further away from the isolation cover relative to the pair of side edges 32, reserving space for the installation of the connecting component 5, thereby ensuring the flatness of the inner surface of the isolation cover and facilitating the production of the isolation cover.

[0033] In some embodiments of this application, the main body 31 is distributed along the outer periphery of the bushing 2. The arched main body 31 undergoes elastic deformation when subjected to thermal expansion, and thus a pair of ear pieces 33 symmetrically extend from a pair of open ends of the main body 31 of the heat insulation bracket 3. A pair of connecting holes 41 are provided on the pair of ear pieces 33. The pair of open ends extend to the open surface. The pair of ear pieces 33 are flush with the open surface. The pair of connecting holes 41 can be connected to the engine compartment by a pair of rods such as bolts. The side edge 32 is designed with rolled edges to form a reinforcing rib structure to avoid stress concentration leading to cracking and improve the overall torsional rigidity of the bracket. The connecting holes 41 of the ear pieces 33 adopt a waist-shaped hole design to ensure precise docking with the engine compartment fixing point.

[0034] The installation method of the stabilizer bar heat insulation component is as follows: First, the bushing 2 is fitted onto the stabilizer bar 1 at the designated position with an interference fit, ensuring that the inner ring surface is completely fitted. Next, the open end of the heat insulation bracket 3 is aligned with the outer circumference of the bushing 2, and it is pre-fixed to the predetermined position in the nacelle with bolts through the connecting hole 41 of the lug 33. Then, the open side of the heat insulation cover 4 is fitted into the heat insulation bracket 3, and after being adjusted to the appropriate position, it is locked to the connecting seat 51 through the connecting hole 41 by the T-bolt of the connecting component 5. At this time, the inner surface of the heat insulation cover 4 and the heat insulation bracket 3 form a seamless fit. Finally, the axial position of the heat insulation cover 4 is finely adjusted through the AB point adjustment function of the connecting hole 41 to ensure that there is no interference with other components in the nacelle. The installation process adopts a modular design, the installation time of a single part is short, and all connections adopt a detachable structure, which facilitates later maintenance and repair.

[0035] The double-layer heat insulation structure of the heat insulation bracket 3 and the heat insulation cover 4 reduces the surface temperature of the bushing 2, significantly slowing down the aging rate of the rubber. The multi-point fixing design of the connecting component 5 ensures that the heat insulation cover 4 remains stable during vehicle driving vibration, avoiding heat insulation failure due to displacement. The split structure and adjustable characteristics make it adaptable to the layout of the engine compartment, improving product versatility. At the same time, the arched semi-enclosed structure of the heat insulation cover 4 reduces material usage while effectively insulating heat, achieving a lightweight design and effectively extending the service life of the stabilizer bar 1 bushing 2.
