[0028] Reference below Figure 1 The suspension assembly 100 according to an embodiment of the present invention is described. By allowing liquid to flow between two groups of hydraulic chambers 31, the vibration energy of the engine is used to offset its own vibration energy, thereby improving the driving stability of the vehicle. The hydraulic component 5 can supply liquid to the hydraulic chamber 31 or discharge the liquid in the hydraulic chamber 31 through the control valve 41, and the stiffness of the hydraulic buffer body 3 can be adjusted, so that the suspension assembly 100 can adapt to different road conditions and improve the ride comfort and driving stability of the vehicle.
[0029] like Figure 1 As shown, a suspension assembly 100 according to an embodiment of the present invention includes: a suspension upper cover plate 1 , a suspension base 2 , a hydraulic buffer body 3 and a hydraulic component 5 .
[0030] The suspension upper cover plate 1 and the suspension base 2 are spaced apart along the first direction; two groups of hydraulic chambers 31 are formed in the hydraulic buffer body 3, and the two groups of hydraulic chambers 31 are spaced apart along the second direction and are respectively supported between the suspension upper cover plate 1 and the suspension base 2, and the two groups of hydraulic chambers 31 are connected through an infusion pipe 4, and a control valve 41 is provided in the infusion pipe 4. The control valve 41 is used to connect or disconnect the two groups of hydraulic chambers 31, and the first direction intersects with the second direction; the hydraulic assembly 5 is connected to the infusion pipe 4, and is suitable for supplying liquid to the hydraulic chamber 31 or discharging the liquid in the hydraulic chamber 31 through the control valve 41.
[0031] Specifically, the suspension upper cover plate 1 is used to withstand the pressure caused by vehicle vibration, and the suspension base 2 is used to realize the installation of the suspension assembly 100 on the vehicle. The suspension upper cover plate 1 and the suspension base 2 are spaced apart in a first direction, so that a certain distance and space is provided between the suspension upper cover plate 1 and the suspension base 2 to facilitate the accommodation of the hydraulic buffer body 3, thereby realizing the installation of the hydraulic buffer body 3. The hydraulic buffer body 3 is used to change its own rigidity according to different road conditions to improve the ride comfort and driving stability of the vehicle. The hydraulic buffer body 3 can be made of rubber material.
[0032] In addition, a hydraulic chamber 31 is formed in the hydraulic buffer body 3. The hydraulic chamber 31 can be used to store liquid and allow liquid to flow in or out. In the process of liquid flowing into or out of the hydraulic chamber 31, the stiffness of the hydraulic buffer body 3 will change with the volume of the liquid in the hydraulic chamber 31, that is, the hydraulic chamber 31 can be used to change the stiffness of the hydraulic buffer body 3, and two groups of hydraulic chambers 31 are formed in the hydraulic buffer body 3. The stiffness of the hydraulic buffer body 3 can be changed together by the two groups of hydraulic chambers 31, which can improve the reliability of changing the stiffness of the hydraulic buffer body 3.
[0033] It should be noted that the stiffness of the hydraulic buffer body 3 is the combined stiffness of the hydraulic buffer body 3 and the liquid in the hydraulic chamber 31. When the hydraulic chamber 31 is filled with liquid, the stiffness of the hydraulic buffer body 3 is maximum. When the liquid in the hydraulic chamber 31 flows out, the volume of the liquid in the hydraulic chamber 31 decreases, and the stiffness of the hydraulic buffer body 3 decreases. Until the liquid in the hydraulic chamber 31 has completely flowed out, the stiffness of the hydraulic buffer body 3 is only its own stiffness, at which point the stiffness of the hydraulic buffer body 3 is minimum. When the liquid flows back into the hydraulic chamber 31, the volume of the liquid in the hydraulic chamber 31 increases, and the stiffness of the hydraulic buffer body 3 increases. The liquid in the hydraulic chamber 31 may be water.
[0034] Moreover, by separating the two groups of hydraulic chambers 31 along the second direction, interference between the two groups of hydraulic chambers 31 can be avoided, ensuring that both groups of hydraulic chambers 31 can work reliably, and the two groups of hydraulic chambers 31 are supported between the suspension upper cover plate 1 and the suspension base 2 respectively, that is, both groups of hydraulic chambers 31 can be set between the suspension upper cover plate 1 and the suspension base 2, and then the suspension upper cover plate 1, the hydraulic buffer body 3 and the suspension base 2 can be set in sequence along the first direction, so that the suspension base 2 can support the hydraulic buffer body 3, and the hydraulic buffer body 3 can support the suspension upper cover plate 1, thereby realizing the setting of the hydraulic buffer body 3 and the suspension upper cover plate 1, and the vibration energy of the vehicle during driving can be transmitted to the hydraulic buffer body 3 through the suspension upper cover plate 1, so that the hydraulic buffer body 3 can change its own stiffness according to different road conditions information to adapt to different road conditions information and improve the ride comfort and driving stability of the vehicle.
[0035] Among them, Figure 1 As shown, the first direction is the up and down direction, and the second direction is the horizontal direction, that is, the second direction can be the left and right direction or the front and back direction, that is, the two groups of hydraulic chambers 31 can be set along the left and right direction, or along the front and back direction, and the first direction intersects the second direction.
[0036] At the same time, the two groups of hydraulic chambers 31 are connected through the liquid infusion tube 4. Even if liquid can flow between the two groups of hydraulic chambers 31 through the liquid infusion tube 4, when the vehicle is driving, the engine itself will vibrate. The energy of the engine vibration can be offset by the flow of liquid between the two groups of hydraulic chambers 31, thereby achieving the purpose of offsetting the vibration energy of the engine itself with the vibration energy of the engine, thereby improving the driving stability of the vehicle. A control valve 41 is also provided in the liquid infusion tube 4. The control valve 41 is used to connect or disconnect the two groups of hydraulic chambers 31, that is, the control valve 41 can be used to control the flow of liquid between the two groups of hydraulic chambers 31. The control valve 41 can be a solenoid valve.
[0037] When the second direction is the front-to-back direction, the two sets of hydraulic chambers 31 can be arranged along the front-to-back direction, so that when the engine vibrates forward, the hydraulic chamber 31 at the front can be squeezed, so that the liquid flows from the hydraulic chamber 31 at the front to the hydraulic chamber 31 at the rear. At this time, if the engine happens to vibrate backward, the original vibration energy of the engine will be offset, achieving the purpose of using the vibration energy of the engine to offset its own vibration energy.
[0038] Furthermore, the suspension assembly 100 is provided with a hydraulic assembly 5 . The hydraulic assembly 5 has a liquid storage space formed therein and can provide pressure for the liquid. Connecting the hydraulic assembly 5 to the liquid infusion tube 4 connects the liquid storage space to the hydraulic chamber 31 via the liquid infusion tube 4, allowing liquid to flow between the liquid storage space and the hydraulic chamber 31. The hydraulic assembly 5 can also provide pressure for the liquid in the liquid infusion tube 4 to control the direction of the liquid flow. Specifically, the hydraulic assembly 5 can supply or discharge liquid from the hydraulic chamber 31 via a control valve 41. When the pressure provided by the hydraulic assembly 5 is less than the pressure of the liquid in the hydraulic chamber 31, the hydraulic assembly 5 can discharge the liquid from the hydraulic chamber 31 via the control valve 41. When the pressure provided by the hydraulic assembly 5 is greater than the pressure in the hydraulic chamber 31, the hydraulic assembly 5 can supply liquid to the hydraulic chamber 31 via the control valve 41. This allows the stiffness of the hydraulic buffer 3 to be adjusted by controlling the flow of liquid, allowing the hydraulic buffer 3 to adapt to different road conditions and improve the ride comfort and driving stability of the vehicle. The hydraulic assembly 5 can be a hydraulic pump.
[0039] The control valve 41 can also be used to control the flow of liquid between the hydraulic chamber 31 and the liquid storage space. By setting only one control valve 41, the flow of liquid in two groups of hydraulic chambers 31 and between the hydraulic chamber 31 and the liquid storage space can be controlled at the same time, which can reduce the number of control valves 41 set and reduce the setting cost.
[0040] According to the suspension assembly 100 of the embodiment of the present invention, the two groups of hydraulic chambers 31 are connected through the infusion tube 4, so that the liquid can flow between the two groups of hydraulic chambers 31, so as to use the vibration energy of the engine to offset its own vibration energy, thereby improving the driving stability of the vehicle, and the infusion tube 4 is connected to the hydraulic component 5, so that the hydraulic component 5 can supply liquid to the hydraulic chamber 31 or discharge the liquid in the hydraulic chamber 31 through the control valve 41, and the stiffness of the hydraulic buffer body 3 can be adjusted, so that the suspension assembly 100 can adapt to different road conditions, improve the ride comfort and driving stability of the vehicle, and help improve user satisfaction.
[0041] In some embodiments, the suspension assembly 100 also includes a first limit member 6, which is located between the two groups of hydraulic chambers 31, and the first limit member 6 extends along the first direction. The first limit member 6 is used to limit the support between the suspension upper cover plate 1 and the suspension base 2 after the hydraulic buffer body 3 is compressed and deformed to a set height along the first direction.
[0042] Specifically, the first limiter 6 can play a limiting role to protect the hydraulic buffer body 3. The first limiter 6 is extended along the first direction, and the first limiter 6 can be used to limit in the first direction to avoid excessive pressure of the suspended upper cover plate 1 on the hydraulic buffer body 3, which causes excessive deformation and damage of the hydraulic buffer body 3. The first limiter 6 is set between the two groups of hydraulic chambers 31, and the first limiter 6 can be set in the middle area of the hydraulic buffer body 3 to make the pressure of the suspended upper cover plate 1 on the hydraulic buffer body 3 on both sides of the first limiter 6 equal, so as to balance the force and avoid tilting. The number of the first limiters 6 can be reduced, further reducing the setting cost. At the same time, the first limiter 6 can also be used to separate the two groups of hydraulic chambers 31 to ensure the reliability of the operation of the two groups of hydraulic chambers 31.
[0043] In addition, the first limit member 6 is used to limit and support the hydraulic buffer body 3 between the suspension upper cover plate 1 and the suspension base 2 after the hydraulic buffer body 3 is compressed and deformed to a set height along the first direction, that is, the height of the hydraulic buffer body 3 along the first direction has a set value. When the suspension upper cover plate 1 squeezes the hydraulic buffer body 3 due to vehicle vibration, causing the hydraulic buffer body 3 to be deformed to a set height along the first direction, the first limit member 6 can be limit and support the hydraulic buffer body 3 between the suspension upper cover plate 1 and the suspension base 2 to support the suspension upper cover plate 1, thereby preventing the suspension upper cover plate 1 from further squeezing the hydraulic buffer body 3, causing the hydraulic buffer body 3 to be excessively deformed and damaged and fail.
[0044] In some embodiments, the first limiting member 6 is integrally formed in the hydraulic buffer body 3 ; or, the first limiting member 6 is connected to one of the suspension upper cover plate 1 and the suspension base 2 .
[0045] Specifically, the first limit member 6 is located between the two groups of hydraulic chambers 31, and the first limit member 6 can be integrally formed in the hydraulic buffer body 3 to reduce the number of structural parts and assembly steps, and can achieve a fixed connection between the first limit member 6 and the hydraulic buffer body 3 to ensure the reliability of the operation of the first limit member 6; or, the first limit member 6 extends along the first direction, and after the hydraulic buffer body 3 is compressed and deformed to a set height, it can be limited and supported between the suspended upper cover plate 1 and the suspended base 2, and the first limit member 6 can be connected to one of the suspended upper cover plate 1 and the suspended base 2, that is, the first limit member 6 can be connected to the suspended upper cover plate 1, or the first limit member 6 can be connected to the suspended base 2, both of which can achieve the installation of the first limit member 6 to ensure the reliable operation of the first limit member 6.
[0046] In some embodiments, the suspension assembly 100 also includes a second limit member 7, there are two second limit members 7, the two second limit members 7 are spaced apart and distributed along the second direction, and the two groups of hydraulic chambers 31 are located between the two second limit members 7, and the second limit member 7 is used to limit and support the hydraulic buffer body 3 after the hydraulic buffer body 3 is compressed and deformed to a set width along the second direction.
[0047] Specifically, the second limit member 7 can play a limiting role to protect the hydraulic buffer body 3. By setting two second limit members 7, the hydraulic buffer body 3 can be protected by two second limit members 7 at the same time, so as to improve the reliability of protecting the hydraulic buffer body 3. The two second limit members 7 are spaced apart and distributed along the second direction, and the two groups of hydraulic chambers 31 are set between the two second limit members 7, so that the hydraulic buffer body 3 can be set between the two second limit members 7, so that the two second limit members 7 can limit the hydraulic buffer body 3 on both sides of the hydraulic buffer body 3 respectively, thereby protecting the hydraulic buffer body 3.
[0048] In addition, the second limit member 7 is used to limit and support the hydraulic buffer body 3 after the hydraulic buffer body 3 is compressed and deformed to a set width along the second direction, that is, the width of the hydraulic buffer body 3 along the second direction has a set value. When the suspended upper cover 1 squeezes the hydraulic buffer body 3 due to vehicle vibration, causing the hydraulic buffer body 3 to be deformed to the set width along the second direction, the second limit member 7 can be limit and support the hydraulic buffer body 3 to support the hydraulic buffer body 3 and prevent the hydraulic buffer body 3 from being damaged and failing due to excessive deformation.
[0049] Among them, it should be noted that the first limit member 6 is arranged between the two groups of hydraulic chambers 31, and the two groups of hydraulic chambers 31 are arranged between the two second limit members 7, so that the hydraulic buffer body 3 can be limited by the first limit member 6 and the second limit member 7 at the same time, thereby improving the reliability of limiting and protecting the hydraulic buffer body 3, and effectively improving the working reliability of the hydraulic buffer body 3.
[0050] In some embodiments, the second limiting member 7 is connected to the suspension upper cover 1 or the suspension base 2 and is configured to extend along the first direction.
[0051] Specifically, the second limit member 7 is used to protect the hydraulic buffer body 3. The second limit member 7 can be connected to the suspended upper cover plate 1 or the suspended base 2, that is, the second limit member 7 can be connected to the suspended upper cover plate 1, or the second limit member 7 can be connected to the suspended base 2 to achieve the installation of the second limit member 7 and ensure the reliable operation of the second limit member 7. The second limit member 7 can be constructed to extend along the first direction, and the setting length of the second limit member 7 can be increased, so that when the second limit member 7 supports the hydraulic buffer body 3, the contact area between the second limit member 7 and the hydraulic buffer body 3 will be larger, and the second limit member 7 will have a better supporting effect on the hydraulic buffer body 3.
[0052] In such Figure 1 In the embodiment shown, the second position-limiting member 7 is connected to the suspension upper cover plate 1 , and the second position-limiting member 7 can be installed by connecting the second position-limiting member 7 to the suspension upper cover plate 1 , thereby ensuring reliable operation of the second position-limiting member 7 .
[0053] In some embodiments, both ends of the suspension upper cover plate 1 in the second direction are provided with a bending portion 11 extending toward the suspension base 2 , and the two second limiting members 7 are respectively sleeved outside the two bending portions 11 in a one-to-one correspondence.
[0054] Specifically, the bending portion 11 is used to realize the installation of the second limit member 7. The two ends of the suspended upper cover plate 1 in the second direction are provided with bending portions 11, and the two second limit members 7 can be installed through the two bending portions 11, and the bending portions 11 are constructed to extend toward the suspension base 2, that is, the two bending portions 11 can be extended along the first direction, which can increase the setting length of the bending portions 11, and the second limit member 7 is sleeved outside the bending portion 11, which can increase the connection length between the bending portion 11 and the second limit member 7, and improve the connection reliability between the two, and the two second limit members 7 are respectively sleeved outside the two bending portions 11 one by one, that is, for each second limit member 7, a bending portion 11 is provided to cooperate with it to realize the reliable installation of the second limit member 7, so that the two second limit members 7 can be used to reliably protect the hydraulic buffer body 3 in the second direction.
[0055] In some embodiments, the suspension assembly 100 further includes a signal receiving device 8 and a control module. The signal receiving device 8 is used to receive vehicle signals, and the control module is adapted to control the operation of the control valve 41 and the hydraulic assembly 5 according to the signal receiving device 8 .
[0056] Specifically, the signal receiving device 8 and the control module can be used to achieve automatic control of the suspension assembly 100, wherein the signal receiving device 8 can be used to receive vehicle signals, such as signals from the driver turning the steering wheel and signals from vehicle vibration, and can transmit the received signals to the control module. The control module can analyze, process and make decisions based on the signals, and issue instructions to the control valve 41 and the hydraulic assembly 5, causing the control valve 41 and the hydraulic assembly 5 to perform corresponding actions to adjust the stiffness of the hydraulic buffer body 3 and improve the ride comfort and driving stability of the vehicle. The control module can be connected to the control valve 41 and the hydraulic assembly 5 to facilitate control of the control valve 41 and the hydraulic assembly 5. The signal receiving device 8 can also be integrated with the control module to reduce the number of components and reduce the difficulty of operation.
[0057] When there is a sharp turn on the road, the driver will swerve the steering wheel according to the road condition information. At this time, the signal receiving device 8 will receive the signal of the driver turning the steering wheel and transmit the signal to the control module. After analyzing and processing the signal, the control module knows that the control valve 41 and the hydraulic component 5 need to be closed at this time, and sends instructions to the control valve 41 and the hydraulic component 5 according to the analysis results to close the control valve 41 and the hydraulic component 5. At this time, the liquid cannot flow between the hydraulic buffer body 3 and the hydraulic component 5. The hydraulic buffer body 3 has a large rigidity and can lock the relative position between the engine and the vehicle body 202, so that the center of gravity of the vehicle can be kept stable, so that the vehicle can turn smoothly, and the driving stability of the vehicle can be improved.
[0058] When potholes appear on the road, the vehicle will vibrate when passing through the potholes. At this time, the signal receiving device 8 will receive the vibration signal of the vehicle and transmit the signal to the control module. After analyzing and processing the signal, the control module knows that the stiffness of the hydraulic buffer body 3 needs to be reduced at this time, and sends instructions to the control valve 41 and the hydraulic component 5 according to the analysis results to open the control valve 41 and the hydraulic component 5. At this time, the pressure provided by the hydraulic component 5 is reduced, and the liquid will flow from the hydraulic chamber 31 to the hydraulic component 5, reducing the stiffness of the hydraulic buffer body 3, thereby improving the ride comfort of the vehicle when driving at low speeds.
[0059] When there are no potholes on the road for a long time, that is, when the vibration signal on the vehicle disappears, the signal receiving device 8 will receive the signal from the vehicle and transmit the signal to the control module. After analyzing and processing the signal, the control module knows that the stiffness of the hydraulic buffer body 3 needs to be increased at this time, and sends instructions to the control valve 41 and the hydraulic component 5 according to the analysis results to open the control valve 41 and the hydraulic component 5. At this time, the pressure provided by the hydraulic component 5 increases, and the liquid will flow from the hydraulic component 5 to the hydraulic chamber 31, so that the stiffness of the hydraulic buffer body 3 increases, thereby improving the ride comfort of the vehicle when driving at high speed.
[0060] In some embodiments, the suspension base 2 is provided with a sleeve portion 21 that passes through along the first direction, and there are two sleeve portions 21; wherein, the liquid infusion tube 4 includes a liquid supply tube body 42 and two connecting tube bodies 43, and the two connecting tube bodies 43 are respectively passed through the two sleeve portions 21 to communicate with the two groups of hydraulic chambers 31 respectively. One end of the liquid supply tube body 42 is connected to the two connecting tube bodies 43 and a control valve 41 is provided at the connection point, and the other end of the liquid supply tube body 42 is connected to the hydraulic component 5.
[0061] Specifically, a sleeve portion 21 is provided on the suspension base 2. The sleeve portion 21 is used to protect the infusion tube 4 to prevent the infusion tube 4 from being crushed and failing. The sleeve portion 21 is passed through the suspension base 2 along the first direction, and the sleeve portion 21 can be extended from one side of the suspension base 2 to the other side. The setting length of the sleeve portion 21 can be increased, and the reliability of the sleeve portion 21 in protecting the infusion tube 4 can be improved. It is also convenient to guide the infusion tube 4 from one side of the suspension base 2 to the other side through the sleeve portion 21 to connect the infusion tube 4 with other components.
[0062] Furthermore, the liquid infusion tube 4 comprises a liquid supply tube body 42 and two connecting tube bodies 43. The two connecting tube bodies 43 are respectively passed through the two sleeve parts 21, so that the two connecting tube bodies 43 can be protected one by one by the two sleeve parts 21, and the reliability of protecting the two connecting tube bodies 43 can be improved. The two connecting tube bodies 43 are respectively connected to the two groups of hydraulic chambers 31, so that even if liquid can enter the hydraulic chamber 31 or be discharged from the hydraulic chamber 31 through the connecting tube bodies 43, and one end of the liquid supply tube body 42 is connected to the two connecting tube bodies 43, the two connecting tube bodies 43 can be connected to the two groups of hydraulic chambers 31. The connecting pipe body 43 is connected to the connecting pipe body 43, and the other end is connected to the hydraulic component 5. The hydraulic component 5 can be connected to the hydraulic buffer body 3 through the liquid supply pipe body 42 and the connecting pipe body 43, so that the liquid can flow between the hydraulic component 5 and the hydraulic cavity 31. In addition, a control valve 41 is provided at the connection between the connecting pipe body 43 and the liquid supply pipe body 42. The flow of liquid between the hydraulic cavity 31, or the flow of liquid between the hydraulic cavity 31 and the hydraulic component 5 can be controlled by the control valve 41, which can reduce the number of control valves 41 and reduce the setting cost.
[0063] In some embodiments, two groups of hydraulic chambers 31 are symmetrically distributed in the hydraulic buffer body 3; wherein each group includes at least one hydraulic chamber 31, and at least one hydraulic chamber 31 of one group is distributed in a one-to-one correspondence with at least one hydraulic chamber 31 of the other group.
[0064] Specifically, the suspension upper cover plate 1 and the suspension base 2 are spaced apart along the first direction, and the two groups of hydraulic chambers 31 are spaced apart along the second direction. When the vehicle vibrates, the suspension upper cover plate 1 will squeeze the hydraulic buffer body 3 under the action of vibration energy, and the two groups of hydraulic chambers 31 are symmetrically distributed in the hydraulic buffer body 3, so that the pressure of the suspension upper cover plate 1 on the two groups of hydraulic chambers 31 can be equal, which can balance the force and avoid tilting.
[0065] Among them, each group includes at least one hydraulic chamber 31, that is, the number of hydraulic chambers 31 in each group can be two, three or more, so that the stiffness of the hydraulic buffer body 3 can be changed by at least one hydraulic chamber 31, which can improve the reliability of changing the stiffness of the hydraulic buffer body 3, and the hydraulic chambers 31 of the two groups are distributed one-to-one, that is, for each hydraulic chamber 31, there is a hydraulic chamber 31 in another group that corresponds to it, that is, it is symmetrically distributed with it, so that the pressure of the suspended upper cover plate 1 on the two groups of hydraulic chambers 31 can be equal, which can balance the force and avoid tilting.
[0066] The utility model also provides a vehicle.
[0067] A vehicle according to an embodiment of the present invention includes a powertrain 201, a vehicle body 202, and a suspension assembly 100 according to any of the above-described embodiments. The powertrain 201 is supported on a suspension upper cover plate 1, and a suspension base 2 is connected to the vehicle body 202. By connecting the suspension base 2 to the vehicle body 202, the suspension assembly 100 can be installed on the vehicle, ensuring the reliable operation of the suspension assembly 100. The powertrain 201 is supported on the suspension upper cover plate 1 so that when the vehicle is driving, vibration energy on the powertrain 201 can be transmitted to the hydraulic buffer body 3 through the suspension upper cover plate 1. The hydraulic buffer body 3 can then adjust its own stiffness according to different road conditions, thereby improving the vehicle's ride comfort and driving stability.
[0068] For example, Figure 1 As shown, the suspension base 2 can be connected to the vehicle body 202 via a plurality of spaced-apart connectors 203 to achieve installation of the suspension assembly 100 on the vehicle. This can improve the reliability and stability of the installation of the suspension assembly 100, improve the reliability of the operation of the suspension assembly 100, facilitate installation and removal of the suspension assembly 100, and reduce subsequent maintenance costs. The connectors 203 can be bolts.
[0069] Furthermore, it should be noted that the suspension upper cover plate 1 and the power assembly 201 may also be connected via a connector 203 to enhance the reliability of vibration energy transmission.
