Description

Technical Field

[0001] The embodiments of the present application relate to the field of vehicle technology, and in particular to a hydraulic mount and a vehicle. Background Art

[0002] The suspension is a component that connects the vehicle body and the powertrain. It can fix the powertrain to ensure that the powertrain works normally on the vehicle body. It can also reduce the vibration and noise transmitted to the vehicle body by the powertrain, thereby improving the driving comfort of the entire vehicle. In addition, it can also prevent large displacement of the powertrain, thereby preventing the powertrain from colliding with other components in the cabin due to excessive displacement.

[0003] Currently, hydraulic mounts are commonly used to effectively dissipate the vibration energy transmitted to the powertrain by road excitation. These mounts generally consist of an upper cavity, a lower cavity, and a decoupling membrane. Liquid flows between the upper and lower cavities. During vehicle operation, the decoupling membrane can vibrate to change the flow pattern of the liquid when the hydraulic mount experiences stiffness hardening at high frequencies and small amplitudes. However, the vibration of the decoupling membrane also makes it prone to collisions with other components, causing unusual noises. To address this issue, reducing the gap between the decoupling membrane and other components is often the solution. Reducing the gap shortens the vibration path of the decoupling membrane, thereby reducing impact. However, this approach makes it difficult for the decoupling membrane to respond promptly when stiffness hardening occurs, resulting in a high stiffness for the hydraulic mount and impacting vibration reduction performance.

The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0035] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to changes in the orientation of the components in the drawings.

For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0037] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0038] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0039] The embodiments of the present application provide a hydraulic mount and a vehicle. The hydraulic mount is used to connect the vehicle body and powertrain. It should be noted that the vehicle in this application can refer to a large car, a small car, a special-purpose vehicle, etc. For example, based on the vehicle model, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other vehicle models. A vehicle generally has a body, wheels, a powertrain, and other components, and the body and powertrain are connected via the hydraulic mount in this application.

[0040] Existing hydraulic mounts generally include an upper cavity, a lower cavity, and a decoupling membrane. During vehicle operation, the decoupling membrane is prone to collision with other components, resulting in abnormal noise.

[0041] In the hydraulic mount provided in the embodiment of the present application, a plurality of convex strips with at least two different extension directions are provided on the decoupling membrane. When the decoupling membrane bounces due to the bumps of the vehicle, the convex strips come into contact with other components, which can effectively reduce abnormal noise. At the same time, the convex strips can also play a good role in disturbing the flow when the liquid flows through the decoupling membrane, thereby effectively increasing the fluid resistance and further improving the vibration reduction ability of the hydraulic mount.

[0042] The following describes in detail the driving assistance device and vehicle provided in the embodiments of the present application in conjunction with the accompanying drawings.

[0043] In some embodiments, reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the hydraulic mount includes a mount body 100 and a spacer 200 .

[0044] The suspension body 100 includes a main rubber 110, an outer skeleton 120 and a bottom membrane 130. A hydraulic chamber 121 is provided on the outer skeleton 120. The main rubber 110 and the bottom membrane 130 are respectively connected to the two ends of the hydraulic chamber 121 to close the two ends of the hydraulic chamber 121 through the main rubber 110 and the bottom membrane 130. The separator 200 is inserted into the hydraulic chamber 121 and has an interference fit with the outer skeleton 120, thereby separating the hydraulic chamber 121 into a first cavity 1211 and a second cavity 1212 arranged in an upper and lower relationship. Of course, the separator 200 is provided with a flow channel 220 connecting the first cavity 1211 and the second cavity 1212. The first cavity 1211 and the second cavity 1212 are filled with liquid, such as ethylene glycol.

[0045] Among them, the suspension body 100 can also include an inner skeleton 140, a first side bracket 500 and a second side bracket 600. The inner skeleton 140 is located in the main rubber 110 and is rigidly connected to the first side bracket 500 through bolts and other components. The first side bracket 500 is used to connect the vehicle's powertrain, and the second side bracket 600 is used to connect the vehicle body. The first side bracket 500 and the second side bracket 600 can both be integrally formed by aluminum die-casting.

[0046] In addition, the suspension body 100 may further include a stopper and a bottom film frame 150. The stopper may be pressed into the first side bracket 500 using a riveting process, etc., to limit the position of the first side bracket 500. The bottom film frame 150 is used to engage with the outer frame 120 to secure the bottom film 130 to the outer frame 120.

[0047] When the vehicle is traveling on a significantly bumpy road, road excitation causes the powertrain to vibrate significantly. Since the powertrain and the inner frame 140 are rigidly connected by bolts, the main rubber 110 is significantly deformed. The deformation of the main rubber 110 causes the volume of the first cavity 1211 to change. When the main rubber 110 deforms downward, the volume of the first cavity 1211 is reduced, and the pressure in the second cavity 1212 increases. The increased pressure in the second cavity 1212 causes the bottom membrane 130 to deform to balance the increased pressure in the second cavity 1212. When the main rubber 110 deforms upward, the volume of the first cavity 1211 increases and the pressure decreases. The deformed bottom membrane 130 releases the pressure, which acts on the liquid in the second cavity 1212, causing the liquid in the second cavity 1212 to flow back to the first cavity 1211 through the flow channel 220. Since the engine vibration will cause the main rubber 110 to deform back and forth, the liquid in the first cavity 1211 and the second cavity 1212 will flow back and forth through the flow channel 220. Since there is viscous damping between the liquids and there is also resistance between the liquid and the flow channel 220, the liquid can quickly consume the vibration energy of the powertrain when flowing back and forth in the first cavity 1211 and the second cavity 1212, thereby quickly attenuating the vibration and effectively solving the aftershock problem of the vehicle when driving on a bumpy road.

[0048] In some embodiments, see Figure 6 and Figure 7 As shown, the hydraulic mount further includes a cover plate 400 and a decoupling membrane 300 . A mounting groove 210 is provided on the partition 200 . The decoupling membrane 300 is located in the mounting groove 210 . The cover plate 400 is covered on the mounting groove 210 to limit the position of the decoupling membrane 300 in the mounting groove 210 .

[0049] Among them, the bottom of the mounting groove 210 is provided with at least one third through hole. When the decoupling membrane 300 moves due to vibration, the liquid can pass through the gap between the decoupling membrane 300 and the mounting groove 210 and flow between the first cavity 1211 and the second cavity 1212 through the third through hole.

[0050] After the hydraulic mount experiences dynamic stiffness hardening under small-amplitude excitation of 20-75 Hz, the liquid in the first cavity 1211 and the second cavity 1212 can flow through the gap between the decoupling membrane 300 and the flow channel 220, changing the flow mode of the original flow liquid in the flow channel 220 and avoiding resonance between the reciprocating flow liquid in the flow channel 220 and the flow channel 220, thereby solving the phenomenon of dynamic stiffness hardening under small-amplitude excitation of 20-75 Hz and improving the NVH (Noise, Vibration, and Harshness) performance of the entire vehicle.

[0051] However, the decoupling membrane 300 is prone to collide with the cover plate 400 and the bottom of the mounting groove 210 to produce abnormal noise during use. In this regard, in this embodiment, a plurality of ridges 310 with at least two different extension directions are provided on the decoupling membrane 300. The ridges 310 are used to contact the bottom of the mounting groove 210 or the cover plate 400, that is, a plurality of ridges 310 are provided on the surface of the decoupling membrane 300 facing the cover plate 400 and the surface facing the bottom of the mounting groove 210.

[0052] When the decoupling membrane 300 collides with the cover plate 400 and the mounting groove 210, the ridges 310 collide with the cover plate 400 and the mounting groove 210, reducing the collision surface and buffering the impact between the decoupling membrane 300, the cover plate 400, and the mounting groove 210, thereby reducing abnormal noise during use of the hydraulic mount. Furthermore, the ridges 310 in this embodiment have at least two different extension directions, meaning that the ridges 310 are not arranged along the same extension direction. This ensures that when liquid flows through the surface of the decoupling membrane 300, it is blocked by the ridges 310 extending in different directions. This effectively enhances the vibration reduction effect of the hydraulic mount by providing a better flow disturbance through the ridges 310.

[0053] In some embodiments, the plurality of ridges 310 include first ridges 310 extending along a first direction and second ridges 310 extending along a second direction, and the first direction and the second direction are perpendicular to each other.

[0054] The first and second ridges 310 extend perpendicularly to each other, providing a better flow disturbance when the liquid flows through the decoupling membrane 300. However, those skilled in the art are well aware that adding ridges 310 in too many directions and distributing them in a disordered manner can significantly increase the manufacturer's processing costs. However, in this embodiment, only ridges 310 are provided in two directions, which does not increase the processing difficulty and thus does not significantly increase the processing costs.

[0055] It is understandable that the first ridges 310 and the second ridges 310 can be arranged in an alternating and disordered manner, or can be arranged according to a certain pattern. Of course, arranging the first ridges 310 and the second ridges 310 according to a certain pattern can further reduce processing costs.

[0056] In some embodiments, the decoupling film 300 includes a main body 330 and arc-shaped portions 340 disposed at both ends of the main body 330 , and the main body 330 is rectangular.

[0057] Specifically, the main body 330 can be configured as a rectangular plate-like structure, with the side of the curved portion 340 facing away from the main body 330 being a curved surface, and the side close to the main body 330 being a rectangular surface. The two ends of the curved surface are connected to the two ends of the rectangular surface, and the curved portion 340 is connected to the end of the main body 330. Of course, the chord length of the curved portion 340, that is, the length of its rectangular surface, is adapted to the width of the main body 330, thereby effectively connecting with the main body 330 to form a structure similar to an ellipse. This approach can effectively avoid resonance between the reciprocating liquid and the flow channel 220, and can also save space, allowing the hydraulic mount to adapt to the Y-direction space within the powertrain cabin, avoiding the problem of the hydraulic mount being unable to be installed due to insufficient space.

[0058] In some embodiments, the second direction is parallel to the extension direction of the decoupling film 300 , a plurality of first ridges 310 are evenly arranged on the main body 330 , and at least one second ridge 310 is arranged on the arc portion 340 .

[0059] Specifically, see Figure 7 As shown, multiple first ridges 310 can be evenly divided into multiple columns and arranged on the main body 330. The number of first ridges 310 in each column is determined according to the width of the main body 330 and the length of the first ridges 310, and second ridges 310 are arranged on the arc portion 340. The number of second ridges 310 can be determined according to the size of the arc portion 340 and the size of the second ridges 310, and the setting position of the second ridges 310 on the arc portion 340 can be determined according to the actual installation conditions.

[0060] Such a configuration can, on the one hand, achieve a better flow disturbance effect and reduce processing costs, and on the other hand, can also make the ridges 310 more evenly distributed on the decoupling membrane 300 .

[0061] It is understandable that the above examples are merely illustrative, and the first ridges 310 and the second ridges 310 may also be provided in other manners, which are not limited in this embodiment.

[0062] For example, the first ridges 310 and the second ridges 310 may be arranged at intervals, for example, one second ridge 310 is arranged between two adjacent first ridges 310 .

[0063] Exemplarily, the first ridges 310 are divided into multiple columns, and a column of second ridges 310 is disposed between two adjacent columns of first ridges 310 .

[0064] In some embodiments, see Figure 7As shown, an annular protrusion 320 is provided on the edge of the decoupling membrane 300, and the convex strip 310 is located on the inner side of the annular protrusion 320. The height of the annular protrusion 320 is greater than or equal to the height of the convex strip 310, thereby effectively improving the buffering effect through the cooperation of the annular protrusion 320 and the convex strip 310.

[0065] Specifically, annular protrusions 320 are provided on two opposing sides of the decoupling membrane 300, arranged along the edge of the decoupling membrane 300. When the decoupling membrane 300 vibrates due to road excitation, if the height of the annular protrusions 320 protruding from the surface of the decoupling membrane 300 is greater than the height of the ridges 310 protruding from the surface of the decoupling membrane 300, the annular protrusions 320 first contact the cover plate 400 or the bottom of the mounting groove 210 to provide cushioning. When the annular protrusions 320 deform to the same height as the ridges 310, the ridges 310 and the annular protrusions 320 then simultaneously provide cushioning. If the annular protrusions 320 and the ridges 310 are the same height, the ridges 310 and the annular protrusions 320 directly and simultaneously provide cushioning.

[0066] In some embodiments, the width of the ridge 310 gradually increases in the direction away from the surface of the decoupling membrane 300, that is, the cross-section of the ridge 310 can be set to a structure similar to a triangle or a trapezoid, and the area of one end close to the cover plate 400 or the bottom of the mounting groove 210 is smaller than the area of the connection with the decoupling membrane 300. When the ridge 310 collides with the cover plate 400 or the bottom of the mounting groove 210, the ridge 310 can gradually deform, reduce vibration, and improve the buffering effect.

[0067] In some embodiments, in order to further reduce the weight of the hydraulic suspension, a plurality of liquid inlet holes 420 are provided on the cover plate 400, and the projection of the liquid inlet holes 420 in the height direction of the decoupling membrane 300 is located inside the decoupling membrane 300, that is, the liquid in the first cavity 1211 can reach the decoupling membrane 300 through the liquid inlet holes 420, and will not directly enter the flow channel 220 in large quantities through the liquid inlet holes 420. At the same time, there is a skeleton between adjacent liquid inlet holes 420 that can limit the decoupling membrane 300, which can not only allow the liquid to reach the decoupling membrane 300, but also limit the position of the decoupling membrane 300, and can also effectively reduce the weight of the cover plate 400.

[0068] In some embodiments, see Figure 8 As shown, the separator 200 is provided with a flow channel 220 which is arranged around the side of the installation groove 210, and a flow blocking portion 240 is provided in the flow channel 220 to cut off the flow channel 220 through the flow blocking portion 240, that is, the flow channel 220 is arranged in a ring shape, but after the flow blocking portion 240 is provided, the flow channel 220 becomes a C-shaped structure, which is not connected at the beginning and the end.

[0069] Among them, such as Figure 8As shown, the separator 200 can be set to a square shape, and the shape of the flow channel 220 can be similar to that of the decoupling membrane 300, which is elliptical or similar to that of the separator 200. This embodiment does not limit this.

[0070] A first through hole 230 is provided on the separator 200 to connect the second cavity 1212 with the flow channel 220 through the first through hole 230. The cover plate 400 is covered above the flow channel 220 and the decoupling membrane 300. A second through hole 410 is provided on the cover plate 400 to connect the first cavity 1211 with the flow channel 220 through the second through hole 410. The second through hole 410 and the first through hole 230 are respectively arranged on both sides of the flow blocking portion 240, so that the liquid can only enter the flow channel 220 from the first cavity 1211 through the second through hole 410, or enter the second cavity 1212 from the flow channel 220 through the second through hole 410. Similarly, the liquid in the flow channel 220 can only enter the second cavity 1212 through the first through hole 230, or the liquid in the second cavity 1212 can only enter the flow channel 220 through the first through hole 230, thereby effectively extending the flow path of the liquid, increasing the damping, and thus improving the vibration reduction effect. At the same time, the configuration of this embodiment makes the width of the flow channel 220 wider, which can increase the liquid flow rate and flow resistance, and further enhance the vibration reduction effect.

[0071] It can be understood that the cover plate 400 not only closes the mounting groove 210 but also closes the flow channel 220. Therefore, an annular positioning protrusion can be set on the side of the partition 200 close to the cover plate 400. The flow channel 220 and the mounting groove 210 are both located on the inner side of the positioning protrusion, and the upper surface of the wall between the mounting groove 210 and the flow channel 220 can be located in the same plane as the upper surface of the positioning protrusion. The cover plate 400 is covered on the positioning protrusion, so the flow channel 220 and the mounting groove 210 can be closed at the same time.

[0072] An embodiment of the present application further provides a vehicle, comprising a vehicle body, a powertrain, and the hydraulic mount in the above embodiment, wherein the hydraulic mount is used to connect the vehicle body and the powertrain.

[0073] The structure and working principle of the hydraulic mount have been described in detail in the above embodiments, and the connection method between the hydraulic mount and the vehicle body and the powertrain is well known to those skilled in the art and will not be described in detail in this embodiment.

[0074] The serial numbers of the embodiments of this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments.
