Description
Technical Field
[0001] The embodiments of the present application relate to the field of vehicle technology, and in particular to a suspension cushion assembly and a vehicle. Background Art
[0002] In the existing technology, as people's demand for driving comfort performance improves, reducing the flutter (continuous vibration) of the entire vehicle when passing over uneven roads has become a more important issue at present. Traditional suspensions mostly use bushing-type rubber suspensions, which have no pre-stressed structure and cannot effectively solve or reduce the flutter of the vehicle when passing over bumpy roads (such as speed bumps). As a result, drivers are prone to continuous vibration or long-term vibration when passing over roads such as speed bumps, affecting the driving experience. Utility Model Content
[0003] In view of this, an embodiment of the present application provides a suspension cushion assembly, which improves driving comfort under high-speed conditions and enhances the driver's driving experience on uneven roads.
[0004] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:
[0005] In a first aspect, an embodiment of the present application provides a suspension cushion assembly, which is used for a vehicle and includes a body side bracket, a powertrain side bracket and a main rubber part, wherein the body side bracket is used to be fixedly connected to the body, and a mounting hole is provided on the body side bracket; the powertrain side bracket is used to be fixedly connected to the powertrain, and at least a portion of the powertrain side bracket is provided on one side of the thickness direction of the body side bracket; the main rubber part is clamped in the mounting hole, the main rubber part is interference fit with the body side bracket, the main rubber part is fixedly connected to the powertrain side bracket, and the main rubber part is constructed so that a gap is provided between the upper end of the main rubber part and the mounting hole when the powertrain side bracket and the powertrain are connected.
[0006] The suspension cushion assembly provided in the embodiments of the present application is configured such that a gap is provided between the upper end of the main rubber component and the mounting hole when the powertrain-side bracket is connected to the powertrain by forming an interference fit between the main rubber component and the vehicle body-side bracket. When the powertrain-side bracket is connected to the powertrain, a gap is maintained between the upper end of the main rubber component and the mounting hole. The main rubber component has a relatively low stiffness, which reduces vibration and noise during vehicle travel and improves driving comfort under high-speed conditions. When the vehicle passes over speed bumps or uneven roads, the main rubber component has a relatively high stiffness, which reduces the vibration amplitude of the powertrain at the suspension cushion assembly and rapidly attenuates the vibration, improving the driver's driving experience on uneven roads.
[0007] In a possible implementation of the present application, a vulcanized exoskeleton is further included, which is arranged between the main rubber component and the peripheral wall of the mounting hole. After the vulcanized exoskeleton is vulcanized and connected to the main rubber component, it is interference fit with the vehicle body side bracket.
[0008] In a possible implementation of the present application, the upper end of the vulcanized exoskeleton is open.
[0009] In a possible implementation of the present application, in a projection on a plane perpendicular to the thickness direction of the vehicle body side bracket, the outer peripheral wall of the vulcanized exoskeleton is W-shaped, and the inner peripheral wall of the mounting hole that cooperates with the vulcanized exoskeleton is also W-shaped.
[0010] In a possible implementation of the present application, a limiting structure is provided at one end of the vehicle body side bracket away from the powertrain side bracket, and the limiting structure is fixedly connected to a portion of the inner peripheral wall on the lower side of the mounting hole.
[0011] In a possible implementation of the present application, a limit block is further included, which is arranged on a side of the body side bracket away from the limit structure and is fixedly connected to the body side bracket, and is used to abut against at least part of the powertrain side bracket.
[0012] In a possible implementation of the present application, a boss is provided at the upper end of the main rubber member, and a free end of the boss abuts against the inner peripheral wall of the mounting hole.
[0013] In a possible implementation of the present application, there are multiple bosses, and the multiple bosses are sequentially spaced apart along the length direction of the vehicle body side bracket.
[0014] In a possible implementation of the present application, along the width direction of the body side bracket, the interference L between the main rubber part and the body side bracket is ≥2.5 mm; and / or, along the width direction of the body side bracket, when the powertrain side bracket and the powertrain are connected, the gap D between the upper end of the main rubber part and the mounting hole is ≥1.5 mm.
[0015] In a second aspect, an embodiment of the present application provides a vehicle comprising the above-mentioned suspension cushion assembly.
[0016] The vehicle provided in the embodiments of the present application utilizes the aforementioned suspension cushion assembly, wherein the main rubber component is interference-fitted with the vehicle body side bracket, and the main rubber component is fixedly connected to the powertrain side bracket. The main rubber component is constructed so that a gap is provided between the upper end of the main rubber component and the mounting hole when the powertrain side bracket is connected to the powertrain. When the vehicle is traveling on a highway, a gap is maintained between the upper end of the main rubber component and the mounting hole. The main rubber component has a relatively low stiffness, which reduces vibration and noise during vehicle driving and improves driving comfort under high-speed conditions. When the vehicle passes over a speed bump or uneven road surface, the main rubber component has a relatively high stiffness, thereby reducing the vibration amplitude of the powertrain at the suspension cushion assembly and rapidly attenuating the vibration, thereby improving the driver's driving experience on uneven roads.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.
[0035] An embodiment of the present application provides a suspension cushion assembly. It should be noted that the suspension cushion assembly in the present application is an important component of the vehicle suspension system, usually located between the powertrain and the vehicle body, and mainly plays the role of vibration reduction, vibration isolation and support.
[0036] It should be noted that in the embodiments of the present application, the specific material of the suspension cushion assembly is not further limited. For example, the materials used in the suspension cushion assembly include steel, plastic, and rubber, etc., which can meet the processing requirements of different suspension cushion assemblies.
[0037] The suspension cushion assembly provided in the embodiment of the present application is specifically used for an extended-range vehicle, and the powertrain is an extended-range powertrain.
[0038] For example, some suspension cushion assemblies, located between the engine and the vehicle body, primarily provide vibration reduction, isolation, and support, playing a crucial role in improving the vehicle's ride comfort and driving stability. During use, regular maintenance and replacement are essential to ensure proper function.
[0039] On this basis, refer to Figure 1 and Figure 2 The embodiment of the present application also provides a suspension cushion assembly 100, including a vehicle body side bracket 1, a powertrain side bracket 2 and a main rubber component 3.
[0040] Specifically, the vehicle body side bracket 1 is used to be fixedly connected to the vehicle body, realizing the connection between the suspension cushion assembly 100 and the vehicle body, and further realizing the force transmission between the suspension cushion assembly 100 and the vehicle body; the powertrain side bracket 2 is used to be fixedly connected to the powertrain, realizing the connection between the suspension cushion assembly 100 and the powertrain, and further realizing the force transmission between the suspension cushion assembly 100 and the powertrain. Among them, at least a part of the powertrain side bracket 2 is provided in the thickness direction of the vehicle body side bracket 1 (such as Figure 5 side of the third direction shown).
[0041] Reference Figure 1 and Figure 2 The body-side bracket 1 is provided with a mounting hole 11, into which the main rubber member 3 is inserted. The main rubber member 3 is fixedly connected to the powertrain-side bracket 2. The main rubber member 3 and the body-side bracket 1 have an interference fit, and the main rubber member 3 and the body-side bracket 1 are tightly connected, thereby achieving a tight connection between the powertrain-side bracket 2 and the body-side bracket 1, which is not prone to loosening. Furthermore, a high pressure is generated between the mating surfaces of the main rubber member 3 and the body-side bracket 1, ensuring that the connection between the main rubber member 3 and the body-side bracket 1 can reliably transmit loads during operation and maintain a stable connection even in vibration environments.
[0042] The main rubber member 3 is configured such that a gap is provided between the upper end of the main rubber member 3 and the mounting hole 11 when the powertrain-side bracket 2 is connected to the powertrain.
[0043] The road of the highway is smooth. When the vehicle is traveling on the highway, the suspension cushion assembly 100 is less stimulated by the road. When the vehicle is a range-extended vehicle, since the range-extended powertrain is only used for power generation, the torque output is small. The suspension cushion assembly 100 is less stimulated by the range-extended powertrain. The Z direction of the main rubber member 3 (the up and down direction of the vehicle, such as Figure 1 The deformation in the second direction (as shown) is small, that is, there is still a gap between the upper end of the main rubber part 3 and the mounting hole 11, and the main rubber part 3 has a small rigidity, which reduces the vibration and noise of the vehicle during driving and improves the driving comfort under high-speed conditions.
[0044] When the vehicle passes over a speed bump or an uneven road, the impact excitation transmitted to the suspension cushion assembly 100 by the road surface is relatively large, and the powertrain will also vibrate in the Z direction as the road surface fluctuates or becomes uneven. Figure 2 As shown, under greater excitation, the suspension cushion assembly 100 can more quickly eliminate the gap between the upper end of the main rubber component 3 and the mounting hole 11 through the deformation of the main rubber component 3, so that the upper end of the main rubber component 3 contacts and squeezes the vehicle body side bracket 1. The main rubber component 3 has greater rigidity, so that the vibration amplitude of the powertrain at the suspension cushion assembly 100 is small and the vibration can be quickly attenuated, thereby improving the driving experience of the driver on uneven roads.
[0045] The suspension cushion assembly 100 provided in the embodiment of the present application is configured such that a gap is provided between the upper end of the main rubber component 3 and the mounting hole 11 when the powertrain-side bracket 2 is connected to the powertrain by forming an interference fit between the main rubber component 3 and the vehicle body-side bracket 1. When the powertrain-side bracket 2 is connected to the powertrain, a gap is maintained between the upper end of the main rubber component 3 and the mounting hole 11. The main rubber component 3 has a low stiffness, which reduces vibration and noise during vehicle travel and improves driving comfort under high-speed conditions. When the vehicle travels over speed bumps or uneven roads, the main rubber component 3 has a high stiffness, which reduces the vibration amplitude of the powertrain at the suspension cushion assembly 100 and rapidly attenuates the vibration, improving the driver's driving experience on uneven roads.
[0046] For example, the vehicle body side bracket 1 is made of aluminum alloy high-pressure integral casting, the powertrain side bracket 2 is made of aluminum alloy high-pressure integral casting, and the main rubber component 3 is made of natural rubber.
[0047] In some embodiments of the present application, reference is made to Figure 2 and Figure 4The suspension cushion assembly 100 also includes a vulcanized exoskeleton 4, which is positioned between the main rubber component 3 and the peripheral wall of the mounting hole 11. After being vulcanized and connected to the main rubber component 3, the vulcanized exoskeleton 4 is interference-fitted with the vehicle body side bracket 1. During the vulcanization process, the rubber's linear macromolecules undergo cross-linking, forming a three-dimensional network structure, significantly improving the rubber's mechanical properties (such as hardness, tensile strength, and elasticity). The vulcanized exoskeleton 4 offers high strength and stability, ensuring a secure connection between the main rubber component 3 and the vehicle body side bracket 1.
[0048] In some embodiments of the present application, reference is made to Figure 2 The suspension cushion assembly 100 also includes a vulcanized inner frame 5, which is positioned between the main rubber component 3 and the outer wall of the powertrain side bracket 2. After being vulcanized and connected to the main rubber component 3, the vulcanized inner frame 5 is interference-fitted with the powertrain side bracket 2. During the vulcanization process, the rubber's linear macromolecules undergo cross-linking reactions, forming a three-dimensional network structure, which significantly improves the rubber's mechanical properties (such as hardness, tensile strength, and elasticity). The vulcanized inner frame 5 has high strength and good stability, ensuring a good connection between the main rubber component 3 and the powertrain side bracket 2.
[0049] Further, refer to Figure 2 and Figure 4 The upper end of the vulcanized exoskeleton 4 is open, so that the upper end of the main rubber part 3 in the vulcanized exoskeleton 4 can be pre-pressed with the mounting hole 11. When the vehicle passes over a speed bump or uneven road surface, the main rubber part 3 has greater rigidity, thereby making the vibration amplitude of the powertrain at the suspension cushion assembly 100 small and the vibration can be quickly attenuated, thereby improving the driving experience of the driver on uneven roads.
[0050] Furthermore, the weight and volume of the vulcanized exoskeleton 4 can be reduced, thereby saving costs and the layout space of the entire vehicle while ensuring strength.
[0051] Further, refer to Figure 2 and Figure 4 In a projection perpendicular to the thickness of the body-side bracket 1, the outer circumferential wall of the vulcanized exoskeleton 4 is W-shaped, as is the inner circumferential wall of the portion of the mounting hole 11 that mates with the vulcanized exoskeleton 4. This W-shaped structure effectively disperses stress when subjected to force, improving overall stability and load-bearing capacity. This also makes the main rubber member 3 and the body-side bracket 1 more stable when subjected to external forces, making them less susceptible to deformation or damage.
[0052] In some embodiments of the present application, reference is made to Figure 6A retaining structure 12 is provided on the end of the body-side bracket 1, distal from the powertrain-side bracket 2. This retaining structure 12 is fixedly connected to a portion of the inner circumferential wall below the mounting hole 11. This position limits the main rubber component 3 in the thickness direction of the body-side bracket 1 when the main rubber component is mounted on the body-side bracket 1, simplifying installation and ensuring a more secure position.
[0053] In some embodiments of the present application, reference is made to Figure 2 and Figure 5 The suspension cushion assembly 100 further includes a limit block 6, which is provided on a side of the vehicle body side bracket 1 away from the limit structure 12 and is fixedly connected to the vehicle body side bracket 1, and is used to abut against at least part of the powertrain side bracket 2, and can be in the Y direction (the left and right direction of the vehicle, such as Figure 1 The first direction shown in the figure limits the powertrain side bracket 2, thereby increasing the reliability of the position of the powertrain side bracket 2.
[0054] In some embodiments of the present application, reference is made to Figure 2 and Figure 3 The upper end of the main rubber member 3 is provided with a boss 31, the free end of which abuts the inner circumferential wall of the mounting hole 11. While the main rubber member 3 can achieve a pre-load function by interfering with the vehicle body side bracket 1 in its free state, it also provides a buffering function, preventing a sudden increase in stiffness when the main rubber member contacts the vehicle body side bracket, thus avoiding any driving shock caused by this sudden increase in stiffness.
[0055] Further, refer to Figure 2 and Figure 3 There are multiple bosses 31, and the multiple bosses 31 are arranged along the length direction of the vehicle body side bracket 1 (such as Figure 1 The suspension cushion assembly 100 is arranged sequentially and spaced apart in the first direction shown. When the vehicle passes over a speed bump or uneven road surface, the main rubber component 3 and the vehicle-side bracket 1 are deformed under greater excitation to more quickly eliminate the gap between the upper end of the main rubber component 3 and the mounting hole 11. This results in more contact and compression between the upper end of the main rubber component 3 and the vehicle-side bracket 1. The main rubber component 3 has greater rigidity, thereby reducing the vibration amplitude of the powertrain at the suspension cushion assembly 100 and rapidly damping the vibration, improving the driver's driving experience on uneven roads. Multiple bosses 31 also provide a buffering function, preventing a sudden increase in the stiffness of the main rubber component 3 when it contacts the vehicle-side bracket, thus avoiding the driving shock caused by the sudden increase in stiffness.
[0056] In some embodiments of the present application, referring to FIG. 1 and FIG. 2 , along the width direction of the vehicle body side bracket 1 (eg Figure 1The interference L between the main rubber component 3 and the body-side bracket 1 is ≥ 2.5 mm. It is understood that, along the width direction of the body-side bracket 1, the interference L between the main rubber component 3 and the body-side bracket 1 can be 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, etc. Along the width direction of the body-side bracket 1, the interference L between the main rubber component 3 and the body-side bracket 1 is not less than 2.5 mm, which ensures the interference between the main rubber component 3 and the body-side bracket 1 and the tight connection between the main rubber component 3 and the body-side bracket 1, thereby achieving a tight connection between the powertrain-side bracket 2 and the body-side bracket 1 and preventing loosening.
[0057] In some embodiments of the present application, referring to Figures 1 and 2, along the width direction of the vehicle body side bracket 1, when the powertrain side bracket 2 is connected to the powertrain, the gap D between the upper end of the main rubber member 3 and the mounting hole 11 is ≥ 1.5 mm. It is understood that along the width direction of the vehicle body side bracket 1, when the powertrain side bracket 2 is connected to the powertrain, the gap D between the upper end of the main rubber member 3 and the mounting hole 11 can be 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, etc. Along the width direction of the vehicle body side bracket 1, when the powertrain side bracket 2 is connected to the powertrain, the gap D between the upper end of the main rubber component 3 and the mounting hole 11 is not less than 1.5 mm. When the vehicle is traveling at a high speed, a gap is maintained between the upper end of the main rubber component 3 and the mounting hole 11. The main rubber component 3 has a relatively low rigidity, which reduces vibration and noise during vehicle driving and improves driving comfort under high-speed conditions.
[0058] The embodiments of the present application provide a vehicle. It should be noted that the vehicle in this application can refer to a large vehicle, a small vehicle, a special-purpose vehicle, etc. For example, based on the vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other vehicle types. A vehicle generally has wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit power provided by the power source to the wheels, causing the wheels to rotate, thereby driving the vehicle.
[0059] It should be noted that in the embodiments of this application, the type of vehicle power source is not limited. For example, for a fuel-powered vehicle, the power source may refer to a gasoline engine, a diesel engine, or other fuel-powered engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; and for a vehicle powered by other means, the power source may refer to a device that generates power.
[0060] An embodiment of the present application further provides a vehicle, comprising the above-mentioned suspension cushion assembly 100 .
[0061] The vehicle provided in the embodiment of the present application utilizes the aforementioned suspension cushion assembly 100. The main rubber component 3 is securely connected to the powertrain-side bracket 2 by interference-fitting the main rubber component 3 with the vehicle body-side bracket 1. The main rubber component 3 is configured so that a gap exists between the upper end of the main rubber component 3 and the mounting hole 11 when the powertrain-side bracket 2 is connected to the powertrain. When the vehicle is traveling at highway speeds, a gap is maintained between the upper end of the main rubber component 3 and the mounting hole 11. The main rubber component 3 exhibits low rigidity, reducing vibration and noise during driving and improving driving comfort under high-speed conditions. When the vehicle travels over speed bumps or uneven roads, the main rubber component 3 exhibits high rigidity, minimizing powertrain vibration amplitude at the suspension cushion assembly 100 and rapidly damping vibration, thereby enhancing the driver's driving experience on uneven roads.
