Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive parts technology, and specifically relates to an aluminum alloy bushing bracket for automotive chassis. Background Technology
[0002] In the modern automotive industry, automotive bushing brackets, as key components connecting the vehicle's suspension system and frame, play a crucial role in the vehicle's stability, comfort, and safety during operation. They not only need to withstand various impacts and vibration loads from the road surface during driving, but also ensure a reliable connection between the frame and suspension system, reducing wear and fatigue damage to components caused by vibration and impact.
[0003] Currently, traditional automotive bushing brackets often employ a single, fixed structure for connection to the vehicle frame, such as rigidly connecting the bracket to the frame directly with only a few bolts, as illustrated by the bushing bracket disclosed in publication number CN207416946U. While this connection method is structurally simple, it presents numerous problems in practical use. On one hand, due to the lack of effective cushioning and shock absorption measures, vibrations and impacts transmitted from the road surface during vehicle operation directly act on the frame and bracket, not only accelerating fatigue damage to the frame and bracket and shortening their service life, but also increasing vibration and noise inside the vehicle, severely impacting ride comfort. On the other hand, a single fixed structure struggles to guarantee the stability of the connection between the bracket and the frame when subjected to complex and variable loads, easily leading to loosening and displacement, which in turn affects vehicle handling performance and driving safety. Utility Model Content
[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an aluminum alloy bushing bracket for automobile chassis to solve the problems mentioned in the background art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] An aluminum alloy bushing bracket for automotive chassis includes a bushing mounting tube, in which the bushing is installed. At least two sets of mounting plates are integrally formed on one side of the bushing mounting tube. The mounting plates are installed on the vehicle frame by bolts and nuts, and an elastic pad is installed between the mounting plate and the vehicle frame.
[0007] Preferably, there is a hollow space between two adjacent sets of mounting plates.
[0008] Preferably, each set of mounting plates includes a first mounting plate and a second mounting plate, with the first mounting plate and the second mounting plate clamping the frame plate.
[0009] Preferably, the elastic pad is U-shaped and is installed between the first mounting plate and the second mounting plate.
[0010] Preferably, the outer wall of the elastic pad is adhered to the side wall of the first mounting plate, the second mounting plate, and the bushing mounting tube.
[0011] Preferably, the inner wall of the bushing mounting tube is provided with multiple sets of elastic protrusions made of flexible material. When the bushing is subjected to force, the bushing and the protrusions squeeze each other or slide relative to each other.
[0012] Preferably, the bushing is interference-fitted or bonded to the inner wall of the bushing mounting tube.
[0013] Preferably, the surface of the protrusion is a smooth sphere.
[0014] Preferably, multiple sets of protrusions are evenly arranged along the circumferential direction to form a protrusion group, and multiple circumferential protrusion groups are set along the axial direction.
[0015] This utility model designs an aluminum alloy bushing bracket for automotive chassis. The one-piece molded bushing bracket helps increase the rigidity between the mounting plate and the bushing mounting tube. When the vehicle is bumpy, the vibration and impact generated are buffered by the elastic pad, avoiding rigid contact between the frame and the bushing bracket, thereby extending the service life of the bushing bracket, reducing noise generation, increasing driving comfort, and improving the connection stability between the frame and the bushing bracket.
[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0022] Example 1
[0023] refer to Figures 1 to 3 The automotive chassis aluminum alloy bushing bracket described in this embodiment includes a bushing mounting tube 1. At least two sets of mounting plates are integrally formed on one side of the bushing mounting tube 1. The mounting plates are mounted on the vehicle frame using bolts 6 and nuts 7. An elastic pad 5 is installed between the mounting plate and the vehicle frame. The integrally formed bushing bracket increases the rigidity between the mounting plate and the bushing mounting tube 1. When the vehicle experiences bumps during driving, the vibrations and impacts are buffered by the elastic pad 5, preventing rigid contact between the vehicle frame and the bushing bracket. This extends the service life of the bushing bracket, reduces noise generation, increases ride comfort, and enhances the connection stability between the vehicle frame and the bushing bracket.
[0024] Preferably, each set of mounting plates includes a first mounting plate 3 and a second mounting plate 4, which clamp the frame plate. An elastic pad 5 is U-shaped and installed between the first mounting plate 3 and the second mounting plate 4. The frame plate is clamped between the elastic pads 5, further enhancing the cushioning effect of the elastic pads 5. The plate is then secured with bolts 6 and nuts 7. Double-sided fixing increases the connection stability between the bushing bracket and the frame.
[0025] Preferably, there is a hollow space between two adjacent sets of mounting plates to reduce the weight of the bushing bracket. As shown in the figure, depending on the number of frame plates installed on the frame, there are two sets of mounting plates. The mounting plates include a first mounting plate 3 and a second mounting plate 4 arranged opposite to each other, and there is a hollow space between the first mounting plate 3 of one set of mounting plates and the second mounting plate 4 of the other set of mounting plates.
[0026] Preferably, a set of bolts 6 is used to connect multiple sets of mounting plates, and multiple sets of nuts 7 are used for fixing. The nuts 7 contact the outer wall of each first mounting plate 3 and second mounting plate 4 respectively, so as to save costs and achieve the same effect as multiple sets of bolts.
[0027] Preferably, the outer wall of the elastic pad 5 is adhered to the side wall of the first mounting plate 3, the second mounting plate 4, and the bushing mounting tube 1. This serves to fix the pad and facilitate installation.
[0028] In traditional bushing brackets, the rubber bushing is in direct contact with the inner wall of the metal bracket. Under frequent vertical vibrations and steering operations of the vehicle, the rubber bushing is prone to wear, aging, and even premature failure. Therefore, multiple sets of elastic protrusions 2 made of flexible material are set on the inner wall of the bushing mounting tube 1. The protrusions 2 are in contact with the bushing. When the bushing is under force, the bushing and the protrusions 2 are squeezed against each other or slide relative to each other. The bushing and the inner wall of the bushing mounting tube 1 are either interference-fitted or stick to each other.
[0029] When the bushing support is subjected to external forces, such as bumps and vibrations during vehicle operation and impacts from uneven road surfaces, the elastic buffer protrusions 2 are the first points to come into contact with the bushing. Because the elastic modulus of protrusions 2 is much lower than that of the metal material of the support body, protrusions 2 will preferentially undergo elastic deformation upon application of force, dispersing the stress originally concentrated on a localized area of the bushing across multiple protrusions 2. Simultaneously, during elastic deformation, the buffer protrusions 2 absorb some vibration energy. For example, when a vehicle passes over a speed bump, the vibration energy is transmitted to the bushing support, and the buffer protrusions 2 are compressed. The internal molecular chains rub against each other, converting some of the vibration energy into heat energy, which is then dissipated, reducing the repeated impact of vibrations on the bushing and improving its durability.
[0030] Preferably, the surface of the protrusion 2 is a smooth spherical surface to increase the contact area with the bushing.
[0031] Preferably, lubricating oil is applied to the surface of the protrusion 2 when installing the bushing. The lubricating oil reduces the friction between the protrusion 2 and the bushing, reduces wear, and protects both the protrusion 2 and the bushing.
[0032] Preferably, multiple sets of protrusions 2 are evenly arranged along the circumferential direction to form a protrusion group, and multiple circumferential protrusion groups are evenly arranged along the axial direction. The even arrangement of the protrusions 2 in the circumferential direction makes the stress distribution more uniform.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.
