For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0036] Reference below Figure 1-Figure 6 A hydraulic bushing assembly 100 according to an embodiment of the present invention is described.

[0037] like Figure 1 As shown, the hydraulic bushing assembly 100 according to an embodiment of the utility model includes a first hydraulic bushing 1 and a connecting assembly, the first hydraulic bushing 1 has a first hydraulic chamber 11, the connecting assembly is connected to the first hydraulic chamber 11, so that the liquid medium in the first hydraulic chamber 11 can enter the connecting assembly, and the liquid medium in the connecting assembly can enter the first hydraulic chamber 11.

[0038] Combination Figure 1 and Figure 2As shown, a hydraulic bushing assembly 100 is provided on the suspension assembly of a vehicle for illustration. The hydraulic bushing is a shock absorbing element widely used in mechanical equipment, and is mainly used to absorb and reduce the vibration and impact generated during the operation of the equipment, protect the key components of the equipment, and improve its working performance and service life. The hydraulic bushing usually contains hydraulic oil (i.e., liquid medium). When subjected to external force, the movement of the hydraulic oil inside the hydraulic bushing generates a damping force, thereby achieving a buffering and shock absorbing effect. This bushing has good dynamic response characteristics and adjustability, and can adapt to the shock absorption requirements under various complex working conditions. In the automotive industry, hydraulic bushings are often used in suspension systems, engine and transmission supports, etc., which can effectively reduce the vibration and noise during vehicle driving and improve driving comfort.

[0039] In this example, the liquid medium in the first hydraulic bushing 1 can enter the connecting component, and the liquid medium in the connecting component can enter the first hydraulic chamber 11. When the vehicle is subjected to a large-value impact load, the liquid encapsulated in the first hydraulic bushing 1 can be pressed out, which can reduce the impact. Under the excitation of high-frequency external loads, the vibration reduction system can weaken the high-frequency dynamic hardening, ensure that the dynamic stiffness is in a lower range, and improve the comfort of the vehicle. Under certain working conditions, the liquid medium in the first hydraulic bushing 1 can be forced to flow out completely. At this time, the corresponding volume stiffness of the first hydraulic bushing 1 that is emptied of liquid is the lowest, which can bring lower dynamic stiffness and effectively meet the performance requirements of extreme working conditions. Here, high-frequency external load refers to the frequent, rapid and periodic changes in loads or forces during the operation of mechanical or structural systems. For example, in occasions such as precision instruments, aircraft, high-speed trains, precision machine tools, and certain specific types of vibration test equipment, the system may be subjected to high-frequency external loads due to factors such as high-speed motion, high-frequency vibration, and transient impact. For this case, it is particularly important to use high-performance shock absorbing elements such as hydraulic bushings. Hydraulic bushings can effectively absorb and disperse these high-frequency loads, reduce their impact on the main structure or key components, prevent excessive fatigue, wear and even damage, and ensure stable operation and long life of the system.

[0040] In addition, combined Figure 1 As shown, the hydraulic bushing generally includes a bushing inner tube 13, a bushing outer tube 12 and an elastic member 14 arranged between the bushing inner tube 13 and the bushing outer tube 12. When the first hydraulic bushing 1 is subjected to load impact, the elastic member 14 will be compressed and the liquid medium in the first hydraulic bushing 1 can be squeezed out. When the load impact disappears, the elastic member 14 restores its deformation. Under the action of negative pressure, the liquid medium can flow back into the first hydraulic bushing 1. Therefore, the friction loss, inertia loss and local loss caused by the back and forth flow of the liquid medium in the circulation channel can effectively attenuate the vibration energy.

[0041] Therefore, according to the hydraulic bushing assembly 100 of the embodiment of the utility model, by connecting the first hydraulic chamber 11 of the first hydraulic bushing 1 with the connecting assembly, the liquid medium in the first hydraulic chamber 11 can flow out when subjected to an impact load, and flow back after the impact load disappears, thereby reducing the impact feeling of the passengers. Under the excitation of high-frequency external loads, the friction loss, inertia loss and local loss caused by the back and forth flow of the liquid medium in the circulation channel can effectively attenuate the vibration energy, thereby improving the vibration reduction effect. Even the liquid medium of the first hydraulic bushing 1 can be completely forced to flow out. At this time, the corresponding volume stiffness of the first hydraulic bushing 1 emptied of liquid is the lowest, which can bring lower dynamic stiffness and effectively meet the performance requirements of extreme working conditions.

[0042] In some embodiments of the present invention, Figure 1-Figure 4 As shown, the connecting component includes a first connecting pipe 21, the end of which is installed on the outer surface of the first hydraulic bushing 1 and connected to the first hydraulic chamber 11. That is, the first connecting pipe 21 can be connected to the first hydraulic chamber 11 of the first hydraulic bushing 1 by setting the first connecting pipe 21, the structure is simple, and the first connecting pipe 21 is generally an elongated tube, and the back and forth flow of the liquid medium in the first connecting pipe 21 can better bring about friction loss, inertia loss and local loss, so as to more effectively attenuate vibration energy, thereby improving the vibration reduction effect. In addition, the length of the first connecting pipe 21 can also be designed according to actual needs, so as to better meet practical applications.

[0043] In some embodiments of the present invention, Figure 1-Figure 4 As shown, the connecting component further includes a liquid storage tank 23, which is connected to the first connecting pipe 21. That is, the liquid medium in the first hydraulic chamber 11 can enter the liquid storage tank 23 along the first connecting pipe 21. It can be understood that the liquid medium can be stored in the liquid storage tank 23, which can better ensure the negative pressure state at both ends of the first connecting pipe 21, that is, in the state of not bearing load impact, the liquid medium in the liquid storage tank 23 can keep the liquid medium in the first hydraulic chamber 11 stably in the first hydraulic chamber 11, so that the first hydraulic bushing 1 maintains a certain dynamic stiffness.

[0044] Furthermore, sufficient liquid medium may be stored in the liquid storage tank 23 . Under certain working conditions, the liquid medium in the liquid storage tank 23 may be transported toward the first hydraulic chamber 11 by driving a pump, thereby meeting the vibration reduction requirements of the first hydraulic bushing 1 .

[0045] In some embodiments of the present invention, Figure 2-Figure 6As shown, the connecting assembly further includes a second connecting pipe 22, the end of which is mounted on the outer surface of the first hydraulic bushing 1 and connected to the first hydraulic chamber 11. That is, by adding the second connecting pipe 22, the efficiency of the liquid medium flowing in and out of the first hydraulic chamber 11 can be improved.

[0046] Optionally, combined Figure 4 As shown, the position where the first connecting pipe 21 is connected to the first hydraulic bushing 1 is the first position, and the position where the second connecting pipe 22 is connected to the first hydraulic bushing 1 is the second position, and the first position and the second position are located on both sides of the radial direction of the center axis of the hydraulic bushing. Therefore, after the second connecting pipe 22 is added, since the first position and the second position are located on both sides of the radial direction of the center axis of the hydraulic bushing, the liquid medium in the first hydraulic chamber 11 can flow out of or into the first hydraulic chamber 11 evenly, and the stability of the first hydraulic bushing 1 can be improved.

[0047] In some examples, the first hydraulic bushing 1 has two first hydraulic chambers 11 therein, the first communicating tube 21 is communicated with one of the first hydraulic chambers 11 , and the second communicating tube 22 may be communicated with the other first hydraulic chamber 11 .

[0048] In some examples, the connecting component may further include a third connecting pipe, or even a fourth connecting pipe. Here, the connecting component is only taken as an example including the first connecting pipe 21 and the second connecting pipe 22, but the present application does not limit the number.

[0049] In some embodiments of the present invention, Figure 1 As shown, the connecting component further includes a liquid storage tank 23, and the first connecting pipe 21 and the second connecting pipe 22 are connected through the liquid storage tank.

[0050] In one example, the liquid in the first hydraulic chamber 11 can enter the liquid storage tank 23 from the first connecting pipe 21, and then flow back to the first hydraulic chamber 11 through the liquid storage tank 23 and the second connecting pipe 22. Therefore, the back and forth flow of the liquid medium can better bring about friction loss, inertia loss and local loss, so as to more effectively attenuate vibration energy, thereby improving the vibration reduction effect.

[0051] In one example, the liquid in the first hydraulic chamber 11 can enter the liquid storage tank 23 from the first connecting pipe 21 and the second connecting pipe 22 at the same time, so that the dynamic stiffness of the first hydraulic bushing 1 can be changed quickly.

[0052] In some embodiments of the present invention, Figure 2 , Figure 5 and Figure 6As shown, the hydraulic bushing assembly 100 further includes: a second hydraulic bushing 3, the second hydraulic bushing 3 has a second hydraulic chamber 31, and the first hydraulic chamber 11 and the second hydraulic chamber 31 are connected through a connecting assembly. Thus, taking the left hydraulic bushing and the right hydraulic bushing of the suspension assembly of the vehicle as an example, the left hydraulic bushing can be the first hydraulic bushing 1, and the second hydraulic bushing 3 can be the right hydraulic bushing. When the vehicle is subjected to a large-value impact load, the liquid encapsulated in the hydraulic bushing on one side can be pressurized to flow into the liquid chamber of the hydraulic bushing on the other side through the connecting pipe, which can reduce the impact.

[0053] In one example, the communication assembly includes a first communication pipe 21 , and the first hydraulic chamber 11 and the second hydraulic chamber 31 are communicated with each other through the first communication pipe 21 .

[0054] In one example, if Figure 5 and Figure 6 As shown, the connecting assembly includes a first connecting pipe 21 and a second connecting pipe 22 , wherein both ends of the first connecting pipe 21 are connected to the first hydraulic chamber 11 and the second hydraulic chamber 31 , respectively, and both ends of the second connecting pipe 22 are connected to the first hydraulic chamber 11 and the second hydraulic chamber 31 , respectively.

[0055] In one example, if Figure 2 As shown, the connecting component includes a first connecting tube 21, a second connecting tube 22 and a liquid storage tank 23. The two ends of the first connecting tube 21 are respectively connected to the first hydraulic chamber 11 and the second hydraulic chamber 31, and the two ends of the second connecting tube 22 are respectively connected to the first hydraulic chamber 11 and the second hydraulic chamber 31. In addition, the first connecting tube 21 and the second connecting tube 22 are also connected to the same liquid storage tank 23.

[0056] In one example, the connecting component includes a first connecting tube 21, a second connecting tube 22 and two liquid storage tanks 23, the two ends of the first connecting tube 21 are respectively connected to the first hydraulic chamber 11 and the second hydraulic chamber 31, the two ends of the second connecting tube 22 are respectively connected to the first hydraulic chamber 11 and the second hydraulic chamber 31, and the first connecting tube 21 is also connected to one liquid storage tank 23, and the second connecting tube 22 is also connected to another liquid storage tank 23.

[0057] In some embodiments of the present invention, Figure 1As shown, the first hydraulic bushing 1 includes a bushing outer tube 12, a bushing inner tube 13, an elastic member 14 and a guide assembly 15. The bushing inner tube 13 is arranged in the bushing outer tube 12, the elastic member 14 is arranged between the bushing outer tube 12 and the bushing inner tube 13, and the guide assembly 15 is arranged between the bushing outer tube 12 and the bushing inner tube 13 to guide the movement direction between the bushing outer tube 12 and the bushing inner tube 13. Therefore, by arranging the guide assembly 15 in the first hydraulic bushing 1, the relative movement direction between the bushing inner tube 13 and the bushing outer tube 12 can be well defined, so that the hydraulic medium in the first hydraulic chamber 11 can stably flow out of the first hydraulic chamber 11, and the first hydraulic bushing 1 can be relatively stable when the hydraulic medium flows back to the first hydraulic chamber 11.

[0058] Optionally, the second hydraulic bushing 3 may also include a bushing outer tube 12, a bushing inner tube 13, an elastic member 14 and a guide assembly 15. Since the structure and principle of the second hydraulic bushing 3 are exactly the same as those of the first hydraulic bushing 1, they are not described in detail here.
