Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a rear suspension assembly for automobiles. Background Technology

[0002] With the continuous development of the automotive industry, the rear suspension assembly, as an important component of the automotive power transmission system, directly affects the vehicle's driving stability and safety through its design and performance.

[0003] Relevant prior art, such as Chinese patent application "A Rear Suspension Part for an Automobile Engine," publication number CN102941800A, discloses a component including a bracket, a bushing disposed within the bracket and interference-fitted with it, and a four-hole mounting surface on the top of the bracket. The bushing includes an inner tube and an outer tube coaxially disposed outside the inner tube, the inner and outer tubes being connected by rubber vulcanization. The rubber has a shear-type symmetrical structure.

[0004] For example, Chinese patent application "A Rear Suspension Bracket", publication number: CN106314117A, discloses: including a shaft support, the upper part of the shaft support is a circular frame, the lower part of the shaft support is a base connected to the circular frame, the base is provided with threaded fixing holes, the upper end faces of the left and right sides of the base are provided with longitudinally arranged first strip teeth, the left and right ends of the base are respectively fitted with U-shaped pressure blocks, the upper part of the U-shaped pressure blocks is folded inward by 90° and pressed on the base on the corresponding side, and the part of the U-shaped pressure block that contacts the base is provided with second strip teeth that cooperate with the corresponding first strip teeth.

[0005] Traditional rear suspension assemblies typically require assembly with a rear suspension mounting bracket. While this structure can meet basic usage requirements to some extent, it also has some drawbacks. Traditional rear suspension assemblies rely on the combination of multiple components, leading to a complex overall assembly process, increased production and maintenance costs, and reduced production efficiency.

[0006] Therefore, innovative designs are urgently needed for the traditional rear suspension assembly structure to reduce component costs, improve assembly efficiency, and enhance overall safety and reliability. Optimizing the rear suspension assembly design can achieve better performance and meet the development needs of the modern automotive industry. Utility Model Content

[0007] The technical problem to be solved by this application is to provide a rear suspension assembly for automobiles, which is composed of bushings and brackets, eliminating the need for additional rear suspension connecting brackets for assembly, thereby reducing the cost of parts and reducing product quality risks.

[0008] The technical solution adopted in this application is as follows: a rear suspension assembly for automobiles, including a bushing and a bracket. The bracket includes a ring sleeved outside the bushing, a first leg and a second leg. The first leg and the second leg are formed by extending from the outer circumferential surface of the ring. The first leg and the second leg are respectively connected to the powertrain. The first leg is provided with a first mounting hole, and the second leg is provided with two second mounting holes. The two second mounting holes are spaced apart in the length direction of the second leg.

[0009] Compared to existing technologies, the advantages of this application are that it integrates the bushing and bracket together, eliminating the need for an additional rear suspension connection bracket in the automotive rear suspension assembly. The structural design of this application reduces assembly steps, improves assembly efficiency, and reduces production and maintenance complexity. Furthermore, by reducing the number of connection points between products, it reduces the quality risk caused by loose connections or failures, thus improving the overall reliability of the product. The design of this application uses the outer circumferential surface of the ring to form the first and second legs, a structure that helps to distribute the load, enhances the overall strength and stability, and thus improves the reliability of the rear suspension assembly. The first mounting hole and two second mounting holes on the bracket connect to the powertrain through multiple mounting holes, effectively ensuring the stability and reliability of the connection. Specifically, the bracket of this application is slender, and under both typical and extreme operating conditions, the stress concentration point is near the middle mounting hole of the part. This design ensures that during a collision, the powertrain will not intrude into the passenger compartment and cause injury to the occupants.

[0010] In some embodiments of this application, the first support leg includes a first bottom surface and first side surfaces disposed on both sides of the first bottom surface. A first mounting post is disposed on the first bottom surface, a first mounting hole is located at the central axis of the first mounting post, and the first mounting post protrudes below the first bottom surface.

[0011] The design of the first support leg, by placing the first mounting post below the first base surface, helps to lower the center of gravity, thereby improving the stability of the overall structure. This design can effectively distribute the load and reduce potential tilting or imbalance during operation.

[0012] In this application, for ease of description, the accompanying drawings are used. Figure 1 Using this as a benchmark to differentiate the upper and lower positions does not imply the actual position of the product during use.

[0013] In some embodiments of this application, one end of the first side is connected to the outer peripheral surface of the ring, the other end of the first side surrounds the outer periphery of the first bottom surface, and the top surface of the first side is an inclined surface.

[0014] The first side connects to the outer circumference of the ring and surrounds the outer circumference of the first bottom surface. This design forms a closed structure, increasing overall strength and stability. This closed design effectively distributes the load applied to the outrigger, reducing local stress concentration. The inclined top surface design further disperses the load under stress, reducing structural damage caused by stress concentration. This design enhances the outrigger's load-bearing capacity under different operating conditions, ensuring stability even under extreme conditions. The inclined surface more effectively absorbs and disperses impact forces from the bottom surface of the first outrigger, enhancing its impact resistance during driving. This is of great significance for improving vehicle driving safety and comfort.

[0015] In some embodiments of this application, a plurality of first reinforcing ribs are provided between the outer peripheral surface of the first mounting post and the first bottom surface, with the first reinforcing ribs located below the first bottom surface. The provision of first reinforcing ribs effectively increases the contact area between the first mounting post and the first bottom surface, enhancing the overall structural strength. This design effectively resists bending and torsional forces that may occur during use, thereby improving the load-bearing capacity of the outrigger. The presence of the first reinforcing ribs helps to evenly distribute the stress applied to the mounting post, reducing localized stress concentration. This reduces the risk of material fatigue and damage, extending the product's service life. When subjected to impact or vibration, the reinforcing ribs provide additional support, helping to absorb and disperse impact forces. This design significantly improves the impact resistance of the outrigger under extreme working conditions, enhancing vehicle safety.

[0016] In some embodiments of this application, the second leg includes a second bottom surface and second side surfaces disposed on both sides of the second bottom surface. Two second mounting posts are disposed on the second bottom surface, and a second mounting hole is located at the central axis of the second mounting post. The second mounting post protrudes above the first bottom surface.

[0017] The design of the second support leg, with its two mounting posts, effectively improves the stability and load-bearing capacity of the support leg. The configuration of two mounting posts evenly distributes the load applied to the support leg, reducing tilting or imbalance caused by a single support point. The design of the second bottom surface and the second side surface forms a closed support structure, which helps to distribute and bear loads from different directions, improving overall strength and stability.

[0018] In some embodiments of this application, one end of the second side is connected to the outer peripheral surface of the ring, and the other end of the second side is connected to the outer peripheral surface of the second mounting post located at the end. The top surface of the second side is an inclined surface, and the second side is located above the second bottom surface.

[0019] The second side connects to the outer circumference of the ring and then to the outer circumference of the second mounting post. This design forms a closed support structure, which helps improve overall stability and strength, resisting externally applied loads. The sloping top surface effectively distributes the load applied to the second side, reducing stress concentration. This design not only improves the overall load-bearing capacity but also reduces the risk of material fatigue and damage caused by excessive local stress.

[0020] In some embodiments of this application, a second reinforcing rib is provided between the outer peripheral surface of the second mounting post located in the middle of the second leg and the second bottom surface. The second reinforcing rib is located above the second bottom surface and is connected to the outer peripheral surface of the ring.

[0021] The second reinforcing rib effectively increases the contact area between the second mounting post and the second bottom surface, enhancing the overall structural strength. This design resists bending and torsional forces that may occur during use, thereby improving the load-bearing capacity of the second support leg. The presence of the second reinforcing rib helps to evenly distribute the stress applied to the mounting post, reducing localized stress concentration. This reduces the risk of material fatigue and damage, extending the product's service life. Under impact or vibration, the reinforcing rib provides additional support, helping to absorb and disperse impact forces. This design significantly improves the support leg's impact resistance under extreme conditions, enhancing vehicle safety. The connection between the second reinforcing rib and the outer circumference of the ring provides additional support and stability, ensuring even stress distribution when connecting the powertrain, reducing stress concentration at the connection point, and thus improving the overall connection reliability.

[0022] In some embodiments of this application, of the two second mounting posts, one second mounting post is located in the middle of the second leg, and the other second mounting post is located at the end of the second leg away from the ring; the bottom surface of the second mounting post is on the same horizontal plane as the bottom surface of the first mounting post.

[0023] The second support leg of this application is longer than the first support leg, and the stress concentration point under typical and extreme working conditions is near the second mounting post in the middle of the second support leg. This design can ensure that the powertrain will not intrude into the passenger compartment and cause injury to people during a collision.

[0024] In some embodiments of this application, the centers of the two second mounting posts and the center of the bushing are located on the same straight line, and the included angle between the first leg and the second leg is an obtuse angle.

[0025] The centers of the two second mounting posts are aligned with the center of the bushing, ensuring even load distribution under stress. This design reduces stress concentration, lowers the risk of material fatigue and damage, and thus improves the overall structural reliability. The obtuse angle between the first and second supports contributes to the stability of the overall support structure. The obtuse angle effectively disperses external forces applied to the supports, reducing vehicle tilting or imbalance during operation.

[0026] In some embodiments of this application, a protrusion is provided on the outer circumferential surface of the ring, the protrusion is connected to one side of the first leg, and the bracket is integrally formed.

[0027] Adding raised strips to the outer circumference of the ring component can effectively increase the overall strength of the support. The design of the raised strips allows the support to better distribute and bear external loads when under stress, reducing local stress concentration and thus improving the reliability of the structure.

[0028] Based on common knowledge in the field, the above-described embodiments can be combined arbitrarily. Attached Figure Description

[0034] The present application will now be described in detail with reference to the accompanying drawings.

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0036] A rear suspension assembly for automobiles, as described in Embodiment 1 Figure 1 As shown, the device includes a bushing 1 and a bracket 2. The bracket 2 includes a ring 3, a first support leg 4, and a second support leg 5, all fitted outside the bushing 1. The first support leg 4 and the second support leg 5 are formed by extending from the outer circumferential surface of the ring 3. The first support leg 4 and the second support leg 5 are respectively connected to the powertrain. This application integrates the bushing 1 and the bracket 2 together, eliminating the need for an additional rear suspension connection bracket 2 in the automotive rear suspension assembly. The structural design of this application reduces assembly steps, improves assembly efficiency, and reduces the complexity of production and maintenance. Furthermore, by reducing the number of connection points between products, it reduces the quality risk caused by loose connections or malfunctions, thereby improving the overall reliability of the product.

[0037] The first support leg 4 is provided with a first mounting hole 9, and the second support leg 5 is provided with two second mounting holes 13, which are spaced apart along the length of the second support leg 5. This structure helps to distribute the load, enhance the overall strength and stability, and thus improve the reliability of the rear suspension assembly. The first mounting hole 9 and the two second mounting holes 13 on the bracket 2 are connected to the powertrain through multiple mounting holes, effectively ensuring the stability and reliability of the connection. Specifically, the bracket 2 of this application is slender, and under typical and extreme working conditions, the stress concentration point is near the mounting hole in the middle of the part. This design can ensure that the powertrain will not intrude into the passenger compartment and cause injury to the occupants during a collision.

[0038] like Figure 2 As shown, a protrusion 15 is provided on the outer circumferential surface of the ring 3, and the protrusion 15 is connected to one side of the first support leg 4. The bracket 2 is integrally formed. The protrusion 15 on the outer circumferential surface of the ring 3 can effectively increase the overall strength of the bracket 2. The design of the protrusion 15 allows the bracket 2 to better distribute and bear external loads when under stress, reducing local stress concentration and thus improving the reliability of the structure.

[0039] Example 2, as Figures 1 to 3As shown, the first support leg 4 includes a first bottom surface 6 and first side surfaces 7 disposed on both sides of the first bottom surface 6. A first mounting post 8 is disposed on the first bottom surface 6, and a first mounting hole 9 is located at the central axis of the first mounting post 8. The first mounting post 8 protrudes and is disposed below the first bottom surface 6. The design of the first support leg 4, by placing the first mounting post 8 below the first bottom surface 6, helps to lower the center of gravity, thereby improving the stability of the overall structure. This design can effectively distribute the load and reduce possible tilting or imbalance during driving.

[0040] In this application, for ease of description, the accompanying drawings are used. Figure 1 Using this as a benchmark to differentiate the upper and lower positions does not imply the actual position of the product during use.

[0041] One end of the first side surface 7 is connected to the outer peripheral surface of the ring 3, and the other end of the first side surface 7 surrounds the outer peripheral surface of the first bottom surface 6. The top surface of the first side surface 7 is entirely inclined. The connection between the first side surface 7 and the outer peripheral surface of the ring 3, and its surrounding the outer peripheral surface of the first bottom surface 6, forms a closed structure, increasing overall strength and stability. This closed design effectively distributes the load applied to the support leg, reducing local stress concentration. The inclined top surface design better disperses the load under stress, reducing structural damage caused by stress concentration. This design enhances the load-bearing capacity of the support leg under different working conditions, ensuring stability even under extreme conditions. The inclined surface more effectively absorbs and disperses the impact force from the bottom surface of the first support leg 4, enhancing the impact resistance of the support leg during driving. This is of great significance for improving vehicle driving safety and comfort.

[0042] A plurality of first reinforcing ribs 16 are provided between the outer peripheral surface of the first mounting post 8 and the first bottom surface 6, with the first reinforcing ribs 16 located below the first bottom surface 6. The first reinforcing ribs 16 effectively increase the contact area between the first mounting post 8 and the first bottom surface 6, enhancing the overall structural strength. This design effectively resists bending and torsional forces that may occur during use, thereby improving the load-bearing capacity of the outrigger. The presence of the first reinforcing ribs 16 helps to evenly distribute the stress applied to the mounting post, reducing local stress concentration. This reduces the risk of material fatigue and damage, extending the product's service life. When subjected to impact or vibration, the reinforcing ribs provide additional support, helping to absorb and disperse impact forces. This design significantly improves the outrigger's impact resistance under extreme conditions, enhancing vehicle safety.

[0043] The second support leg 5 includes a second bottom surface 10 and second side surfaces 11 disposed on both sides of the second bottom surface 10. Two second mounting posts 12 are provided on the second bottom surface 10, and second mounting holes 13 are located at the central axis of the second mounting posts 12. The second mounting posts 12 protrude above the first bottom surface 6. The design of the second support leg 5, by providing two second mounting posts 12, effectively improves the stability and load-bearing capacity of the support leg. The configuration of two mounting posts can evenly distribute the load applied to the support leg, reducing tilting or imbalance caused by a single support point. The design of the second bottom surface 10 and the second side surfaces 11 forms a closed support structure, which helps to distribute and bear loads from different directions, improving the overall strength and stability.

[0044] One end of the second side surface 11 is connected to the outer peripheral surface of the ring 3, and the other end of the second side surface 11 is connected to the outer peripheral surface of the second mounting post 12 located at the end. The top surface of the second side surface 11 is entirely inclined, and the second side surface 11 is located above the second bottom surface 10. This design forms a closed support structure, which helps improve the overall stability and strength, resisting externally applied loads. The inclined top surface design effectively disperses the load applied to the second side surface 11, reducing stress concentration. This design not only improves the overall load-bearing capacity but also reduces the risk of material fatigue and damage due to excessive local stress.

[0045] A second reinforcing rib 14 is provided between the outer peripheral surface of the second mounting post 12 located in the middle of the second support leg 5 and the second bottom surface 10. The second reinforcing rib 14 is located above the second bottom surface 10 and is connected to the outer peripheral surface of the ring 3. The provision of the second reinforcing rib 14 can effectively increase the contact area between the second mounting post 12 and the second bottom surface 10, thereby enhancing the strength of the overall structure.

[0046] Of the two second mounting posts 12, one is located in the middle of the second support leg 5, and the other is located at the end of the second support leg 5 away from the ring 3; the bottom surface of the second mounting post 12 is on the same horizontal plane as the bottom surface of the first mounting post 8. In this design, the length of the second support leg 5 is greater than the length of the first support leg 4, and under both typical and extreme operating conditions, the stress concentration point is near the second mounting post 12 in the middle of the second support leg 5. This design ensures that during a collision, the powertrain will not intrude into the passenger compartment and cause injury to occupants.

[0047] The centers of the two second mounting posts 12 and the center of the bushing 1 are located on the same straight line, and the included angle between the first support leg 4 and the second support leg 5 is an obtuse angle. The fact that the centers of the two second mounting posts 12 and the center of the bushing 1 are on the same straight line ensures even load distribution under stress. This design reduces stress concentration, lowers the risk of material fatigue and damage, and thus improves the overall structural reliability. The obtuse angle between the first support leg 4 and the second support leg 5 helps improve the stability of the overall support structure. The obtuse angle configuration effectively disperses external forces applied to the supports, reducing vehicle tilting or imbalance during operation.
