Description

Technical Field

[0001] This utility model belongs to the field of automotive technology, specifically relating to an automotive suspension and an automotive. Background Technology

[0002] The main suspension spring is a key elastic element (usually a rubber or hydraulic bushing structure) in the engine mount or subframe mount system. Its main functions are to support the weight, isolate engine vibration and impact, and control powertrain displacement. In the prior art, the main suspension spring and the anti-collision pad are usually integrated. For example, patent application number CN202420850941.3 discloses an automotive mount assembly and an automotive vehicle. The mount assembly includes a bracket, a bushing mounted on it, and an anti-collision pad mounted on the bushing. The bushing includes an outer tube, an inner tube, and a rubber main spring. The anti-collision pad includes a first anti-collision pad and a second anti-collision pad. The first anti-collision pad and the second anti-collision pad are respectively located on the first side and the second side of the bushing. The first anti-collision pad and the rubber main spring are integral parts. The first anti-collision pad is located at the first end of the rubber main spring and is integrally formed with the rubber main spring.

[0003] In the laboratory, the main suspension spring (or the entire suspension assembly, or even the entire chassis system) is mounted on a specialized test bench. Using hydraulic actuators and other equipment, accelerated fatigue testing is conducted to simulate various complex and demanding load conditions (bumps, impacts, torsion, etc.) that a vehicle might encounter on real roads. During bench testing, due to excessive loads, material fatigue, design flaws, manufacturing issues, or other reasons, the crash pads may exhibit failure modes such as cracking. This necessitates replacing parts and retesting, but both require time. If the problem recurs, multiple cycles of this process may be necessary. This can severely slow down the development progress of the chassis system and even the entire vehicle project. Utility Model Content

[0004] The purpose of this invention is to provide an automotive suspension system and vehicle, which, by designing the anti-collision pad and the main spring as a separate structure, allows the bench test to continue even if the anti-collision pad cracks during bench testing. This shortens the time required to replace components and improves the development progress of the chassis system and even the entire vehicle project.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: Firstly, an automobile suspension is provided, including a suspension bracket having a mounting cavity that runs through the front and rear, a main spring disposed in the mounting cavity, a mounting seat disposed on one side of the suspension bracket in the front-rear direction, and an anti-collision pad disposed on the mounting seat; the anti-collision pad is detachably connected to the mounting seat, and the anti-collision pad is separate from the main spring.

[0006] In this embodiment of the application, the main spring is provided with a support cavity that runs through the front and rear. The support cavity is provided with an inner frame and a support arm. One side of the inner frame abuts against the main spring, and the other side abuts against the support arm.

[0007] In this embodiment of the application, the support cavity includes a square cavity and a trapezoidal cavity arranged sequentially in the vertical direction. The square cavity and the trapezoidal cavity are connected, and the width of the trapezoidal cavity decreases sequentially from top to bottom.

[0008] In this embodiment, the support arm includes a first connecting part and a second connecting part that are integrally connected. The first connecting part is embedded in the cavity of the bracket, and the second connecting part and the mounting seat are arranged on the same side of the suspension bracket in the front-back direction.

[0009] In this embodiment of the application, the mounting base and the second connecting portion are arranged on different sides of the suspension bracket in the vertical direction.

[0010] In this embodiment, the anti-collision pad is arranged along the vertical direction on the side of the mounting base near the second connection portion.

[0011] In this embodiment of the application, an outer frame and a damping channel are arranged sequentially along the vertical direction inside the mounting cavity, and the outer frame abuts against the damping channel and the main spring.

[0012] In this embodiment of the application, the suspension bracket is provided with a fixing hook, and the fixing hook abuts against the outer frame.

[0013] In this embodiment, the mounting base is provided with an interference groove, the interference groove is provided with a mounting hole, the anti-collision pad is provided with a positioning block, the positioning block is provided with a mounting post, the positioning block is embedded in the interference groove, and the mounting post is inserted into the mounting hole.

[0014] In a second aspect, an automobile is proposed, comprising a frame, a power unit, and the automobile mount described in the first aspect, wherein the automobile mount is disposed on the frame and the power unit is disposed on the automobile mount.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The present invention proposes an automotive suspension and an automotive, which designs the anti-collision pad and the main spring as a separate structure. In this way, during bench testing, if the anti-collision pad cracks, only the anti-collision pad on the mounting base needs to be replaced to continue the bench test, which shortens the time required for replacing components and improves the development progress of the chassis system and even the whole vehicle project.

[0017] 2. The present invention proposes an automobile suspension and automobile, which fixes the support arm by setting a bracket cavity and an inner frame, so that the main spring and the support arm form an interlocking structure, thereby improving the fixing effect of the support arm. Furthermore, by setting a bracket cavity, the contact area between the main spring and the support arm during installation is increased, thereby reducing the stress on the support arm.

[0018] 3. The present invention proposes an automobile suspension and automobile, which, by setting a square cavity and a trapezoidal cavity, the vertical sidewall of the upper square cavity forms a surface contact with the support arm, thereby efficiently transmitting shear force (such as lateral sway of the engine), the right-angle structure provides anti-torsional stiffness and suppresses the circumferential rotation of the support arm, and the hypotenuse of the lower trapezoidal cavity causes the main spring to generate a centripetal compressive force when compressed, thereby improving the tensile strength of the main spring;

[0019] 4. The present invention proposes an automobile suspension and an automobile, by setting the second connecting part and the mounting seat on the same side of the suspension bracket, thereby setting the anti-collision pad and the second connecting part on the same side of the suspension bracket. When the engine violently shakes and impacts the anti-collision pad, the support arm forms a direct force transmission channel, thereby avoiding deformation of the suspension bracket. Moreover, the anti-collision pad is compressed and generates an overturning moment, and the support arm provides a reverse support force, forming a force couple, thereby reducing the torsional stress received by the suspension bracket.

[0020] 5. The present invention provides a car mount and a car, wherein the mounting base and the second connecting part are arranged on different sides of the mount bracket in the vertical direction. When the car is impacted by the road surface, the anti-collision pad responds to the impact first, and then the support arm responds to the impact, thereby avoiding the superposition of impacts that could cause deformation of the mount bracket.

[0031] To more clearly illustrate the technical solutions in the embodiments of this utility model and the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

[0032] Firstly, this utility model embodiment provides an automotive mounting bracket; please refer to [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 It mainly includes a suspension bracket 2, a main spring 3, a mounting base 4, and a crash pad 5.

[0033] In this embodiment, the automotive suspension includes a suspension bracket 2, a main spring 3, a mounting base 4, and a crash pad 5. The suspension bracket 2 has a through mounting cavity 1, and the main spring 3 is arranged within the mounting cavity 1. The mounting base 4 is arranged along the front-rear direction of the suspension bracket 2 on one side of the suspension bracket 2. The crash pad 5 is arranged on the mounting base 4 and is detachably connected to the mounting base 4, and is separate from the main spring 3. This application, by designing the crash pad 5 and the main spring 3 as a separate structure, allows for continued bench testing if the crash pad 5 cracks during bench testing; only the crash pad 5 on the mounting base 4 needs to be replaced. This shortens the time required for component replacement and improves the development progress of the chassis system and even the entire vehicle project.

[0034] It should be noted that the forward and backward directions are... Figure 1 The Y-axis direction in the middle, the up and down direction is Figure 1 The X-axis direction and the left and right directions are... Figure 1 The Z-axis direction in the equation.

[0035] In one possible implementation, the main spring 3 is provided with a support cavity 31 that runs through the front and rear direction. The support cavity 31 is provided with an inner frame 6 and a support arm 7. The inner side of the inner frame 6 abuts against the main spring 3, and the outer side of the inner frame 6 abuts against the support arm 7. The support arm 7 is used to connect the frame and the power unit (including the engine, gearbox and other components). The main spring 3 can be made of rubber, and the support can be made of metal. By setting the support cavity 31 and the inner frame 6 to fix the support arm 7, the main spring 3 and the support arm 7 form an interlocking structure, which improves the fixing effect of the support arm 7. In addition, by setting the support cavity 31, the contact area between the main spring 3 and the support arm 7 during installation is increased, thereby reducing the stress on the support arm 7.

[0036] Preferably, the support cavity 31 consists of a square cavity 311 and a trapezoidal cavity 312 connected sequentially from top to bottom, with the width of the trapezoidal cavity 312 decreasing sequentially from top to bottom. By setting the square cavity 311 and the trapezoidal cavity 312, the vertical sidewall of the upper square cavity 311 forms a surface contact with the support arm 7, thereby efficiently transmitting shear force (such as lateral sway of the engine), the right-angle structure provides torsional stiffness, suppresses the circumferential rotation of the support arm 7, and the hypotenuse of the lower trapezoidal cavity 312 causes the main spring 3 to generate a centripetal compressive force when compressed, thereby improving the tensile strength of the main spring 3.

[0037] In one possible implementation, the support arm 7 includes an integrally connected first connecting part and a second connecting part. The first connecting part is embedded in the bracket cavity 31, and the second connecting part and the mounting seat 4 are arranged on the same side of the suspension bracket 2 in the front-rear direction. By setting the second connecting part and the mounting seat 4 on the same side of the suspension bracket 2, the anti-collision pad 5 and the second connecting part are also set on the same side of the suspension bracket 2. When the engine violently shakes and impacts the anti-collision pad 5, the support arm 7 forms a direct force transmission channel, thereby preventing the suspension bracket 2 from deforming. The anti-collision pad 5 is compressed and generates an overturning moment. The support arm 7 provides a reverse support force, forming a couple and reducing the torsional stress received by the suspension bracket 2.

[0038] Furthermore, the mounting base 4 and the second connecting part are arranged on different sides of the suspension bracket 2 in the vertical direction. When the car is impacted by the road surface, the anti-collision pad 5 responds to the impact first, and then the support arm 7 responds to the impact, thereby avoiding the superposition of impacts that cause the suspension bracket 2 to deform.

[0039] Preferably, the anti-collision pad 5 is arranged in the vertical direction on the side of the mounting base 4 near the second connection part.

[0040] In one possible implementation, an outer frame 8 and a damping channel 9 are arranged sequentially in the vertical direction inside the mounting cavity 1. The outer frame 8 abuts against the main spring 3, and the damping channel 9 abuts against the outer frame 8.

[0041] Furthermore, the suspension bracket 2 is provided with a fixing hook 21, which abuts against the outer frame 8. The connection between the outer frame 8 and the suspension bracket 2 is strengthened by setting the fixing hook 21.

[0042] In one possible implementation, the mounting base 4 is provided with an interference groove 41, and a mounting hole 42 is provided within the interference groove 41. The anti-collision pad 5 is provided with a positioning block 51, and a mounting post 52 is provided on the positioning block 51. The positioning block 51 is embedded in the interference groove 41, and the mounting post 52 is inserted into the mounting hole 42. When installing the anti-collision pad 5, the mounting post 52 is inserted into the mounting hole 42, and then the positioning block 51 is embedded in the interference groove 41. If the anti-collision pad 5 cracks due to bench testing, the anti-collision pad 5 can be removed from the mounting hole 42 and the interference groove 41, and then a new anti-collision pad 5 can be installed in the mounting hole 42 and the interference groove 41. By using the interference groove 41 and the mounting hole 42 to install the anti-collision pad 5, the installation method of the anti-collision pad 5 is simplified, and the time required to replace the anti-collision pad 5 is shortened.

[0043] Secondly, this utility model provides an automobile, which includes a frame, a power unit, and the vehicle mount described in the first aspect. The vehicle mount is mounted on the frame, and the power unit is arranged on the vehicle mount. Both the frame and the power unit are conventional automobile components.
