TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle engine, and particularly relates to an engine suspension and a vehicle. BACKGROUND

[0002] The engine suspension is a device for fixing the engine on the frame, which mainly functions to isolate the vibration generated during the operation of the engine, so as to avoid the direct transmission of the vibration to the vehicle body, thereby improving the smoothness of the vehicle and the comfort of the ride, and also helping to protect the engine and its accessories from damage caused by vibration.

[0003] In the prior art, the engine is usually fixed on the suspension bracket of the engine suspension through fastening screws, and the suspension bracket is fixed on the vehicle body through a rubber support structure, so as to reduce the transmission of the engine vibration to the vehicle body.

[0004] However, since the engine generates continuous vibration during operation, the continuous vibration effect will cause the rubber support structure of the engine suspension to gradually age, and fracture may occur in the stress concentration area, which not only reduces the stability of the engine, but also may pose a potential threat to the safety of the vehicle. CONTENT OF THE UTILITY MODEL

[0005] The present application provides an engine suspension and a vehicle, which relieve the impact of engine vibration on the engine suspension by increasing rubber pads and pads in the engine suspension, thereby enhancing the stability of the engine suspension and ensuring the driving safety of the vehicle.

[0006] In a first aspect, the present application provides an engine suspension, which comprises: an engine front suspension and an engine rear suspension.

[0007] The engine front suspension comprises: a front suspension shell, and a first pad, a first rubber pad, a second pad, a first support block and a second rubber support block which are sequentially arranged on the front suspension shell from bottom to top.

[0008] The engine rear suspension comprises: a rear suspension shell, and a second rubber pad, a third pad, a third support block and a fourth rubber support block which are sequentially arranged on the rear suspension shell from bottom to top.

[0009] In a possible design, the bottom of the second pad is provided with a first protruding structure, the top of the first rubber pad is provided with a groove, and the first protruding structure is clamped into the groove to fix the second pad and the first rubber pad.

[0010] In a possible design, the edge of the second pad is provided with a baffle.

[0012] In a possible design, the first cushion plate comprises an L-shaped main plate and an extension plate, the extension plate is provided with a fixing hole, and a baffle of the L-shaped main plate is located at a connection position of the extension plate.

[0013] In a possible design, the fourth rubber support block has a groove with an upward opening.

[0014] In a possible design, the third support block has a structure of being narrow at the bottom and wide at the top, and the third support block has two contact positions with the second rubber cushion block.

[0015] In a possible design, the first rubber cushion block and the second rubber cushion block are internally provided with an arc-shaped framework.

[0016] In a possible design, the first support block is made of metal.

[0017] In a second aspect, the application provides a vehicle, comprising: an engine and the engine suspension of the first aspect, the front engine suspension connects the front end of the vehicle frame and the engine, and the rear engine suspension connects the rear end of the vehicle frame and the engine.

[0018] This application provides an engine mount and a vehicle. The engine mount includes a front engine mount and a rear engine mount. The front engine mount includes a front mount housing and, from bottom to top, a first pad, a first rubber pad block, a second pad, a first support block, and a second rubber support block, all arranged sequentially on the front mount housing. The rear engine mount includes a rear mount housing and, from bottom to top, a second rubber pad block, a third pad, a third support block, and a fourth rubber support block, all arranged sequentially on the rear mount housing. The following technical effects can be achieved: by designing the pads and blocks in the front and rear engine mounts to be arranged in layers, forming a multi-layer structure, layered vibration damping is achieved, thus broadening the vibration damping frequency band of the engine mount, enhancing the support and vibration damping capabilities of the engine mount, dispersing engine vibration, and reducing noise transmitted to the vehicle body. The layered pads and blocks not only support the engine weight and maintain its positional stability, but also isolate and absorb engine vibrations, reducing vibration transmission to the vehicle body, improving ride comfort, and limiting engine displacement. This prevents engine vibrations from interfering with surrounding components, providing stable support and effective vibration damping, thus significantly reducing the impact of engine vibrations on driving comfort and vehicle durability. By having all components work together, the impact of engine vibrations on the engine mounts is effectively mitigated, enhancing the stability of the engine mounts and ensuring vehicle driving safety. The combination of rubber pads and support blocks provides static rigidity, while the rubber pads ensure dynamic flexibility, balancing engine support stability and vibration isolation. This limits engine displacement during acceleration and braking, preventing collisions between the engine and surrounding components. It ensures both the stability of the engine mount's static support and the flexibility of dynamic vibration damping, effectively isolating vibrations. The use of pads provides a stable support surface and distributes pressure, extending the lifespan of the rubber pads and consequently the engine mount's lifespan. The shear deformation of the rubber pads absorbs engine vibration energy, thus attenuating low-frequency, high-amplitude vibrations such as vehicle idling vibration. When the vehicle is experiencing low-frequency, high-amplitude vibrations, the rubber pads provide high damping to dampen the vibrations, and the support blocks restrict engine displacement. When the vehicle is experiencing high-frequency, low-amplitude vibrations, the rubber pads reduce vibration stiffness, preventing resonance between the engine mount and the engine vibration frequency. The support blocks enhance the rigidity and stability of the engine mount, thereby mitigating the impact of engine vibrations on the engine mount, effectively dispersing stress, enhancing the overall stability of the engine mount, extending its service life, ensuring vehicle safety and reliability, improving ride comfort and handling stability, and ultimately enhancing the user's driving experience.

Any embodiment or design solution described in the present application as "exemplary" or "for example" should not be interpreted as more preferred or more advantageous than other embodiments or design solutions. Rather, the use of the words "exemplary" or "for example" is intended to present the relevant concept in a specific manner. In the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more.

[0033] It should be noted that "at the time of" in the embodiments of the present application can be at the moment when a certain condition occurs, or within a certain period of time after the occurrence of a certain condition, which is not specifically limited in the embodiments of the present application. In addition, the engine mount provided in the embodiments of the present application is only an example, and an engine mount can also include more or less content.

[0034] An engine mount includes a mount bracket and a rubber support structure, which is used to fix an engine on a vehicle or a mechanical device, and its main function is to isolate the vibration generated during engine operation, preventing the vibration from being directly transmitted to the vehicle body, thereby reducing the noise and shaking transmitted to the vehicle body, and improving the smoothness and ride comfort of the vehicle. In addition, the engine mount can also help to protect the engine and its accessories from damage caused by vibration.

[0035] In the prior art, the engine is usually fixed on the suspension bracket by fastening screws, and the suspension bracket is connected to the vehicle body through a rubber support structure to isolate the engine vibration, reduce the transmission of the engine vibration to the vehicle body, and thus improve the smoothness of the vehicle driving, enhance the driving quality of the vehicle and the comfort experience of the passengers.

[0036] However, due to the long-term vibration of the engine, the rubber support structure of the engine suspension may gradually age during long-term use and break under stress. This condition affects the stability of the engine and poses a potential threat to the safety of the vehicle.

[0037] Therefore, the embodiments of the present application provide an engine suspension and a vehicle, which can be used in the technical field of vehicle engine, and aim to solve the above technical problems of the prior art. By adding rubber pads and pads in the engine suspension, the impact of engine vibration on the engine suspension is alleviated, thereby effectively dispersing stress, enhancing the overall stability of the engine suspension, prolonging the service life of the engine suspension, ensuring the safety and reliability of the vehicle driving, improving the riding comfort and control stability of the vehicle, and thus improving the driving experience of the user.

[0038] The technical solutions of the embodiments of the present application and how the technical solutions solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0039] Figure 1 A structure diagram of an engine suspension provided by the embodiments of the present application Figure One . Figure 1 A structure diagram of an engine front suspension 1. As shown in Figure 1 , the engine front suspension 1 includes a front suspension housing 3, and a first pad 7, a first rubber pad 4, a second pad 6, a first support block 8, and a second rubber support block 5 arranged on the front suspension housing 3 in turn from bottom to top.

[0040] Specifically, the front suspension housing 3 is the basic component of the entire engine front suspension 1, which is the base of the entire engine front suspension 1 and is fixed to the front end of the vehicle frame for carrying and protecting the internal components and the engine.

[0041] The first pad 7 is located at the bottom of the engine front suspension 1 and is directly installed on the front suspension housing 3 to provide a stable support surface and disperse pressure. That is, the first pad 7 can provide a flat and solid foundation to evenly distribute the pressure from the engine and components above.

[0042] The first rubber pad 4 is arranged on the first pad plate 7 and is a core damping element of the engine front suspension 1, which absorbs high-frequency vibrations through elastic deformation. The elasticity and damping performance of the rubber material can be used to absorb the vibrations generated during engine operation and reduce the vibrations transmitted to the vehicle body.

[0043] The second pad plate 6 is arranged on the first rubber pad 4 and can further disperse the pressure to support the upper components and further stabilize the structure of the engine front suspension 1 and support the components above.

[0044] The first support block 8 is arranged next to the second pad plate 6 and can enhance the rigidity of the engine front suspension 1 to limit the displacement of the engine.

[0045] The second rubber support block 5 is arranged between the first support block 8 and the front suspension housing 3 and is also made of rubber material. The main purpose is to isolate the vibrations transmitted by the engine to the upper part of the front suspension housing 3, which serves as an auxiliary damping and provides additional damping to further isolate the engine vibrations and ensure the stability of the engine during operation.

[0046] The design combines hard materials (such as the pad plate and support block) with elastic materials (such as the rubber pad), making full use of the nonlinear stiffness characteristics of rubber: soft (vibration isolation) for small vibrations and hard (limiting) for large vibrations. By arranging the first pad plate 7, the first rubber pad 4, the second pad plate 6, the first support block 8, and the second rubber support block 5 in order from bottom to top, a multi-layer structure is formed, layered vibration damping is achieved, the vibration damping frequency band of the engine front suspension 1 is widened, the support and damping capacity of the engine front suspension 1 is enhanced, engine vibrations are dispersed, and noise transmitted to the vehicle body is reduced. Not only can it support the weight of the engine to keep it stable in position, but it can also isolate and absorb engine vibrations, reduce vibration transmission to the vehicle body, improve ride comfort, and limit engine displacement to avoid interference with surrounding components, thereby providing stable support and effective damping for the engine, effectively reducing the impact of engine vibration on driving comfort and vehicle durability. Each component has its specific function, and they work together to effectively alleviate the impact of engine vibration on the engine front suspension 1, enhance the stability of the engine front suspension 1, and ensure the safety of vehicle operation. Through the combined use of the first rubber pad 4 and the first support block 8, the first support block 8 provides static rigidity, and the first rubber pad 4 ensures dynamic flexibility, balancing the stability of engine support and vibration isolation. Limiting engine displacement under conditions such as acceleration and braking avoids collisions with surrounding components, ensuring the stability of the static support of the engine front suspension 1 and providing flexibility for dynamic damping, thereby effectively isolating vibrations. Using the pad plate can provide a stable support surface and distribute pressure, prolonging the service life of the first rubber pad 4 and thus the engine front suspension 1. The shear deformation of the first rubber pad 4 can absorb engine vibration energy, thereby significantly attenuating low-frequency large-amplitude vibrations (such as vehicle idle vibration). When the vehicle is in a low-frequency large-amplitude vibration state (such as idle), the first rubber pad 4 attenuates vibration with high damping, and the first support block 8 limits engine displacement; when the vehicle is in a high-frequency small-amplitude vibration state (such as cruising), the first rubber pad 4 reduces vibration stiffness to avoid resonance between the engine front suspension 1 and the engine vibration frequency. The first support block 8 can enhance the rigidity and stability of the engine front suspension 1, thereby alleviating the impact of engine vibration on the engine front suspension 1, effectively dispersing stress, enhancing the overall stability of the engine front suspension 1, prolonging the service life of the engine front suspension 1, ensuring the safety and reliability of vehicle operation, and improving the ride comfort and handling stability of the vehicle, thereby enhancing the driving experience of users.

[0047] Figure 2 A structural diagram of an engine suspension provided by an embodiment of the present application Figure Two . Figure 2 A structural diagram of an engine rear suspension 2. As Figure 2As shown, the rear engine mount 2 includes a rear mount housing 14, and a second rubber pad 16, a third pad plate 18, a third support block 15, and a fourth rubber support block 17 arranged on the rear mount housing 14 in sequence from bottom to top.

[0048] Specifically, the rear mount housing 14 is the base part of the entire rear engine mount 2, and other components are arranged on the rear mount housing 14 as the base of the entire rear engine mount 2, fixed to the rear end of the frame, used for carrying and protecting the engine and internal components.

[0049] The second rubber pad 16 is arranged on the rear mount housing 14 and can be used to absorb engine vibration and reduce vibration transmission to the vehicle body during engine operation, i.e., has the effect of damping and buffering.

[0050] The third pad plate 18 is located between the second rubber pad 16 and the third support block 15, which can be used to further support and disperse pressure, help to evenly distribute the load, and can also serve to adjust the height and fix other components.

[0051] The third support block 15 is located above the third pad plate 18, which is used to provide stable support for the engine.

[0052] The fourth rubber support block 17 is located between the third support block 15 and the rear mount housing 14, which can also be used for damping and buffering to avoid direct transmission of engine vibration to the upper part of the rear mount housing 14. That is, it is used to further reduce vibration and reduce the impact of engine vibration on the vehicle, while also helping to reduce noise.

[0053] Such a design helps to improve the stability of the engine, reduce the impact of engine vibration on the rest of the vehicle, and thus improve driving comfort and vehicle durability. This multi-level design fully considers the comprehensive needs of damping, support, and stability, and through the cooperation of these components, it provides stable support and damping effect for the engine.

[0054] The engine mount provided by the embodiment includes: a front engine mount and a rear engine mount; the front engine mount includes: a front mount housing, and a first pad plate, a first rubber pad, a second pad plate, a first support block, and a second rubber support block arranged on the front mount housing in sequence from bottom to top; the rear engine mount includes: a rear mount housing, and a second rubber pad, a third pad plate, a third support block, and a fourth rubber support block arranged on the rear mount housing in sequence from bottom to top.

[0055] The following technical effects can be achieved: By designing layered pads and blocks in the front and rear engine mounts to form a multi-layered structure, layered vibration damping broadens the vibration damping frequency band of the engine mounts, enhances their support and vibration damping capabilities, disperses engine vibration, and reduces noise transmitted to the vehicle body. The layered pads and blocks not only support the engine weight and maintain its positional stability but also isolate and absorb engine vibration, reducing vibration transmission to the vehicle body, improving ride comfort, and limiting engine displacement to prevent interference between engine vibration and surrounding components. This provides stable support and effective vibration damping for the engine, effectively reducing the impact of engine vibration on driving comfort and vehicle durability. By enabling all components to work together, the impact of engine vibration on the engine mounts is effectively mitigated, enhancing the stability of the engine mounts and ensuring vehicle driving safety. By combining rubber pads and support blocks, the support blocks provide static rigidity, while the rubber pads ensure dynamic flexibility, balancing the stability of the engine mount with vibration isolation. This limits engine displacement during acceleration and braking, preventing collisions between the engine and surrounding components. It ensures both the stability of the engine mount's static support and the flexibility of dynamic vibration damping, effectively isolating vibrations. Using pads provides a stable support surface and distributes pressure, extending the lifespan of the rubber pads and consequently the engine mount. The shear deformation of the rubber pads absorbs engine vibration energy, attenuating low-frequency, high-amplitude vibrations such as vehicle idling vibrations. When the vehicle is experiencing low-frequency, high-amplitude vibrations, the rubber pads provide high damping to attenuate the vibrations, while the support blocks restrict engine displacement. When the vehicle is experiencing high-frequency, low-amplitude vibrations, the rubber pads reduce vibration stiffness, preventing resonance between the engine mount and the engine's vibration frequency. The support blocks enhance the rigidity and stability of the engine mount, thereby mitigating the impact of engine vibration on the engine mount, effectively dispersing stress, enhancing the overall stability of the engine mount, extending the service life of the engine mount, ensuring the safety and reliability of vehicle operation, and improving the vehicle's ride comfort and handling stability, thus enhancing the user's driving experience.

[0056] Figure 3 A schematic diagram of an engine mount provided in this application embodiment. Figure Three . Figure 3 This is a schematic diagram of the structure of the second pad 6. Figure 3 As shown, the bottom of the second pad 6 is provided with a first protrusion structure 9.

[0057] Figure 4 A schematic diagram of an engine mount provided in this application embodiment. Figure Four . Figure 4 This is a schematic diagram of the structure of the first rubber pad 4. Figure 4As shown, the top of the first rubber pad 4 is provided with a groove, and the first protruding structure 9 is inserted into the groove to fix the second pad 6 and the first rubber pad 4.

[0058] Specifically, the first protruding structure 9 can be mechanically interlocked with the first rubber pad 4. By inserting the first protruding structure 9 at the bottom of the second pad 6 into the groove at the top of the first rubber pad 4, the two components, the second pad 6 and the first rubber pad 4, can be fixed together. This design not only helps to stabilize the relative position between the second pad 6 and the first rubber pad 4, ensuring a tight and stable connection between different components, but also utilizes the material properties of the first rubber pad 4 to achieve vibration reduction and noise reduction, thereby enhancing the vibration damping effect of the engine front mount 1 to a certain extent. This is crucial for improving the overall performance of the vehicle, driving comfort, and extending the service life of the engine front mount 1.

[0059] Furthermore, a baffle is provided at the edge of the second pad 6. The baffle design can further enhance the structural strength of the second pad 6 and prevent it from deforming or being damaged during use. In addition, the baffle can also restrict the movement of the first support block 8, preventing the first support block 8 from sliding or detaching, thereby providing additional support and restraint for the engine, ensuring the stability and reliability of the entire engine front mount 1. At the same time, the baffle also helps to further reduce vibration transmission, protect the various components in the engine front mount 1, and further enhance the durability of the engine front mount 1.

[0060] Figure 5 A schematic diagram of an engine mount provided in this application embodiment. Figure Five . Figure 5 This is a schematic diagram of the structure of the second rubber support block 5. Figure 5 As shown, the top of the second rubber support block 5 is provided with a second protrusion structure 20.

[0061] Specifically, the second protruding structure 20 contacts the front suspension housing 3. By setting the second protruding structure 20 on the top of the second rubber support block 5, the connection between the front suspension housing 3 and the second rubber support block 5 can be strengthened, effectively preventing relative sliding between the two components, the second rubber support block 5 and the front suspension housing 3, thereby improving the structural stability of the engine front suspension 1.

[0062] Furthermore, the first support block 8 is made of metal. Specifically, the first support block 8 is a component directly connected to the engine. Metal materials typically possess high strength and rigidity, effectively withstanding dynamic loads and vibrations from the engine. This ensures that the first support block 8 maintains structural integrity and stability during long-term use, reducing functional failures caused by material fatigue or deformation, thereby reducing maintenance and replacement costs and improving the overall reliability of the engine mount. Moreover, the ambient temperature around the engine is high, especially near the exhaust manifold or other high-temperature components. Compared to other materials such as rubber, metal has better heat resistance and is less prone to softening or damage due to temperature increases, ensuring stable operation of the engine mount even in high-temperature environments. In addition, the metal support block provides more precise installation positioning and better assembly accuracy, which is crucial for engine mounts that require strict control of vibration transmission paths and directions. This helps reduce unwanted vibrations and noise while improving the overall reliability and durability of the engine mount.

[0063] Figure 6 A schematic diagram of an engine mount provided in this application embodiment. Figure Six . Figure 6 This is a schematic diagram of the structure of the first pad 7. (See attached diagram.) Figure 6 As shown, the first pad 7 includes an L-shaped main plate 21 and an extension plate 22. The extension plate 22 is provided with a fixing hole 23, and the baffle of the L-shaped main plate 21 is located at the connection with the extension plate 22.

[0064] Specifically, the first pad 7 consists of two parts: an L-shaped main plate 21 and an extension plate 22. The design of the L-shaped main plate 21 gives it a vertical baffle and a horizontal plate. The first rubber pad 4 is mounted on the horizontal plate. The vertical baffle increases the structural strength of the L-shaped main plate 21 and forms stable support on the side of the first rubber pad 4, preventing the first rubber pad 4 from sliding. By supporting the first rubber pad 4 in two directions, the shear deformation inside the first rubber pad 4 is reduced.

[0065] The extension plate 22 is provided with fixing holes 23, which can be used to fix the first pad 7 to the front suspension housing 3 by bolts or other types of fasteners passing through the fixing holes 23, ensuring that the first pad 7 is stably installed and preventing the position of the first pad 7 from shifting due to vibration or other reasons. The extension plate 22 expands the connection points of the L-shaped main body plate 21, improving the installation flexibility of the L-shaped main body plate 21. Therefore, the design of the first pad 7 takes into account the structural stability and ease of installation, while also providing the necessary flexibility to adapt to different installation scenarios.

[0066] Figure 7 A schematic diagram of an engine mount provided in this application embodiment. Figure Seven .Figure 7 is a structural schematic diagram of the fourth rubber support block 17. As shown in the figure, the fourth rubber support block 17 has a groove with an upward opening. The groove can be matched with the rear suspension housing 14 to enhance the connection strength, thereby ensuring the stability of the connection between the fourth rubber support block 17 and the rear suspension housing 14. Figure 7

[0067] is a structural schematic diagram of the engine suspension provided by the embodiment of the present application Figure 8 . Figure Eight is a structural schematic diagram of the second rubber pad block 16. As shown in the figure Figure 8 and Figure 4 , the first rubber pad block 4 and the second rubber pad block 16 are internally provided with an arc-shaped framework 12. Figure 8 Specifically, the arc-shaped framework 12 can be made of metal or other high-strength materials. In order to improve the carrying capacity and stability of the first rubber pad block 4 and the second rubber pad block 16, while maintaining their elasticity and damping characteristics. The arc-shaped design of the arc-shaped framework 12 helps to more evenly distribute the force exerted on it, improving the elastic properties of the first rubber pad block 4 and the second rubber pad block 16, and avoiding damage to the first rubber pad block 4 and the second rubber pad block 16 due to excessive local pressure, thereby improving the durability and reliability of the structure of the first rubber pad block 4 and the second rubber pad block 16. By setting the arc-shaped framework 12 in the first rubber pad block 4 and the second rubber pad block 16, the flexibility of the rubber material and the firmness of the metal framework are combined, not only improving the carrying capacity of the first rubber pad block 4 and the second rubber pad block 16, but also enhancing its resistance to deformation, so that it can work stably in various complex working environments. The arc-shaped framework 12 as the internal support structure of the first rubber pad block 4 and the second rubber pad block 16 can enhance the compression resistance and shear resistance of the first rubber pad block 4 and the second rubber pad block 16.

[0068] Further, as shown in the figure

[0069] , the third support block 15 has a structure of being narrow at the bottom and wide at the top, and the third support block 15 has two contact positions with the second rubber pad block 16. Figure 2 Specifically, the structure of the third support block 15 being narrow at the bottom and wide at the top helps to increase the stability of the third support block 15. The narrow bottom can reduce the contact area with the rear suspension housing 14, thereby reducing the possibility of friction or adhesion; while the wide top can provide a larger support area, increasing its carrying capacity and stability; by designing the third support block 15 to be narrow at the bottom and wide at the top, the force exerted on the third support block 15 can also be more evenly distributed to the second rubber pad block 16 below, thereby facilitating load dispersion and optimizing vibration absorption effect, effectively avoiding damage caused by excessive local stress.

[0070]

[0071] ​The third support block 15 has two contact positions with the second rubber pad 16, which helps the second rubber pad 16 to better disperse and absorb the engine vibration transmitted by the third support block 15. Each contact position can serve as an independent vibration damping source, thereby improving the vibration damping effect of the entire engine rear suspension 2. In addition, the two contact positions can provide more precise positioning for the third support block 15, ensuring that it does not easily displace during use, thereby enhancing the stability and reliability of the entire engine rear suspension 2.

[0072] Further, the embodiments of the present application also provide a vehicle, which comprises an engine and an engine suspension according to any one of the above embodiments, the engine front suspension connecting the front end of the vehicle frame and the engine, and the engine rear suspension connecting the rear end of the vehicle frame and the engine.
