The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] Hydraulic mounts are important parts of automobile engines, mainly playing the role of support, limit and vibration isolation, which can improve the driving comfort of drivers and passengers. When assembling existing hydraulic mounts, the flow channel components usually have no constraint measures for rotation around the Z axis, which can easily cause the non-flow channel area of ​​the flow channel components to block the injection hole, affecting the injection process. In a small number of solutions with error-proofing structures, manual positioning is required during assembly, which is time-consuming and labor-intensive.

[0031] Reference below Figure 1-Figure 4 A hydraulic suspension assembly according to an embodiment of the present invention is described.

[0032] According to the rubber main spring 11 and the flow channel assembly 12 of the utility model, a accommodating chamber 111 and an injection hole 112 connecting the accommodating chamber 111 with the outside are formed in the rubber main spring 11, and a guide portion 113 is provided on the inner peripheral wall of the accommodating chamber 111; the flow channel assembly 12 can be selectively accommodated in the accommodating chamber 111, and a hydraulic flow channel 121 that can be selectively connected to the injection hole 112 is formed on at least part of the outer periphery of the flow channel assembly 12, and a non-flow channel area 122 is formed on at least another part of the outer periphery of the flow channel assembly 12, and a positioning portion 123 is provided on the non-flow channel area 122; wherein, when the non-flow channel area 122 is directly opposite to the injection hole 112, the positioning portion 123 cooperates with the guide portion 113 to drive the flow channel assembly 12 to rotate so that the injection hole 112 is connected to the hydraulic flow channel 121.

[0033] According to the hydraulic suspension component 1 of the utility model, a accommodating chamber 111 is provided in the rubber main spring 11, and the accommodating chamber 111 can accommodate the flow channel component 12. The accommodating chamber 111 is provided with an injection hole 112, and a hydraulic flow channel 121 is provided on at least part of the periphery of the flow channel component 12. During assembly, the flow channel component 12 is accommodated in the accommodating chamber 111, and the hydraulic flow channel 121 can be directly opposite to and connected with the injection hole 112. At this time, damping fluid can be added to the hydraulic flow channel 121 through the injection hole 112 to facilitate the use of the hydraulic suspension component 1. A guide portion 113 is provided on the inner peripheral wall of the accommodating chamber 111, and a non-flow channel area 122 is formed on the outer periphery of at least another part of the flow channel assembly 12. A positioning portion 123 is provided on the non-flow channel area 122. The positioning portion 123 can cooperate with the guide portion 113 under certain circumstances to drive the flow channel assembly 12 to rotate so that the injection hole 112 is connected with the hydraulic flow channel 121. Specifically, during the assembly of the flow channel assembly 12 and the rubber main spring 11, when the hydraulic flow channel 121 is misaligned with the injection hole 112, the positioning portion 123 cooperates with the guide portion 113, and the flow channel assembly 12 as a whole rotates under the guidance of the guide portion 113 until the hydraulic flow channel 121 is directly opposite to the injection hole 112 and is connected; conversely, if the hydraulic flow channel 121 is directly opposite to the injection hole 112, at this time, the positioning portion 123 is not in contact with the guide portion 113, and the flow channel assembly 12 is not guided by the guide portion 113. The setting of the guide part 113 and the positioning part 123 makes it possible to assemble the flow channel assembly 12 and the rubber main spring 11 without pre-adjusting the angle positioning, and can also realize the connection between the injection hole 112 and the hydraulic flow channel 121, thereby realizing full-angle assembly without dead ends, reducing the assembly difficulty, improving the assembly efficiency, and simplifying the assembly process.

[0034] According to an embodiment of the present invention, a guide slope 1130 is formed on the guide portion 113, which is inclined in the axial direction away from the flow channel assembly 12 and extends in the circumferential direction. The positioning portion 123 is suitable for sliding along the guide slope 1130 when the non-flow channel area 122 is directly opposite to the injection hole 112 to drive the flow channel assembly 12 to rotate. Specifically, Figure 3 and 4As shown, a guide slope 1130 is provided on the guide part 113, and the guide slope 1130 extends in the circumferential direction and is inclined in the axial direction. When the non-flow channel area 122 is directly opposite to the injection hole 112 during the assembly of the flow channel assembly 12 and the rubber main spring 11, the positioning part 123 contacts the guide slope 1130. Since the assembly of the flow channel assembly 12 and the rubber main spring 11 in the axial direction requires external force, the positioning part 123 moves along the guide slope 1130 under the action of the external force, so that the flow channel assembly 12 as a whole rotates in the circumferential direction. When the flow channel assembly 12 rotates a certain angle, the positioning part 123 is separated from the guide slope 1130, and at this time, the hydraulic flow channel 121 is connected with the injection hole 112. The setting of the guide slope 1130 realizes the correction function of the positioning part 123 driving the flow channel assembly 12 to rotate, simplifies the process of the guide part 113 guiding the positioning part 123, and improves the assembly efficiency of the flow channel assembly 12 and the rubber main spring 11.

[0035] According to an embodiment of the utility model, the guide portion 113 includes a first plate 1131 and a second plate 1132, the first plate 1131 and the second plate 1132 are connected to each other and are inclined in the circumferential direction away from each other to define a guide bevel 1130, and the guide bevel 1130 is axially opposite to the injection hole 112. Specifically, the guide portion 113 is provided with a first plate 1131 and a second plate 1132 connected to each other, the first plate 1131 and the second plate 1132 extend in the circumferential direction away from each other, and at the same time, the first plate 1131 and the second plate 1132 are respectively inclined in the direction away from the flow channel assembly 12 when extending. It can be understood that the inclination directions of the first plate 1131 and the second plate 1132 are symmetrically arranged. After assembly, some surfaces of the first plate 1131 and the second plate 1132 facing the flow channel assembly 12 form the guide bevel 1130 in the above embodiment, that is, the guide bevel 1130 may not be an inclined surface inclined in one direction, but may present an inclined surface similar to a "V" shape. As Figure 2 , Figure 3 and Figure 4 As shown, when the hydraulic channel 121 and the injection hole 112 are interlaced during the assembly of the channel assembly 12 with the rubber main spring 11, the positioning portion 123 contacts the guiding slope 1130. At this time, under the action of external force, the positioning portion 123 can move along the guiding slope 1130 formed by the first plate 1131, or along the guiding slope 1130 formed by the second plate 1132, that is, the positioning portion 123 can drive the channel assembly 12 to rotate clockwise or counterclockwise according to the contact position with the guiding slope 1130 during actual assembly and finally connect the hydraulic channel 121 with the injection hole 112. The arrangement of the first plate 1131 and the second plate 1132 makes the rotation correction process of the channel assembly 12 not restricted by the circumferential direction, and the final connection between the injection hole 112 and the hydraulic channel 121 can be achieved regardless of clockwise or counterclockwise rotation.

[0036] According to an embodiment of the utility model, the width of the first plate 1131 and the second plate 1132 gradually decreases in the direction approaching each other. It can be understood that, since the guide slope 1130 is directly opposite to the injection hole 112 in the axial direction, the first plate 1131 and the second plate 1132 are configured to affect the filling of the damping fluid. Specifically, the hydraulic suspension assembly 1 sets the first plate 1131 and the second plate 1132 to gradually decrease in width in the direction approaching each other. The width here can be understood as the radial size of the first plate 1131 and the second plate 1132. The gradually decreasing width can define an avoidance space at the connection between the first plate 1131 and the second plate 1132. When the hydraulic flow channel 121 is connected to the injection hole 112, the damping fluid can enter the hydraulic flow channel 121 through the avoidance space, thereby avoiding the influence of the guide portion 113 on the filling of the damping fluid.

[0037] According to an embodiment of the utility model, the hydraulic suspension assembly 1 further includes a limiting portion 114, the two ends of which are respectively connected to the first plate 1131 and the second plate 1132, and the limiting portion 114 is suitable for abutting against the positioning portion 123 in the first direction. Specifically, the hydraulic suspension assembly 1 is further provided with a limiting portion 114 on the inner peripheral wall of the accommodating cavity 111, the two ends of which are respectively connected to the free end of the first plate 1131 and the free end of the second plate 1132, when the positioning portion 123 drives the flow channel assembly 12 to rotate a certain angle along the guide inclined surface 1130, the positioning portion 123 moves to the limiting portion 114 and abuts against the surface of one side of the limiting portion 114 facing the flow assembly in the axial direction, fixing the assembly position of the flow channel assembly 12 in the axial direction, so that the hydraulic flow channel 121 can maintain a communication relationship with the injection hole 112.

[0038] According to an embodiment of the utility model, the length of the non-flow area 122 in the circumferential direction is less than the length of the guide slope 1130 in the circumferential direction. Since the non-flow area 122 will block the filling of the damping liquid when it is directly opposite to the injection hole 112, the circumferential length relationship between the non-flow area 122 and the guide slope 1130 will affect the connection between the injection hole 112 and the hydraulic channel 121 after the flow channel assembly 12 rotates. Specifically, the length of the non-flow area 122 in the circumferential direction can be less than the length of the guide slope 1130 in the circumferential direction, ensuring that after the positioning portion 123 is separated from the guide slope 1130, the non-flow area 122 and the injection hole 112 are staggered, avoiding incomplete correction of the flow channel assembly 12 when the positioning portion 123 slides out of the guide slope 1130.

[0039] In some embodiments, the setting position of the positioning portion 123 will affect the rotation angle of the flow channel assembly 12. Here, one case is taken as an example. If the positioning portion 123 is set at the circumferential center position of the non-flow channel area 122, and when the flow channel assembly 12 is assembled with the rubber main spring 11, the positioning portion 123 is axially opposite to the connection point between the first plate 1131 and the second plate 1132. At this time, it is necessary to satisfy that half of the circumferential length of the non-flow channel area 122 is less than the circumferential length of the guide slope 1130 formed by the first plate 1131 or the second plate 1132. In this case, when the positioning portion 123 slides out of the guide slope 1130, the end of the non-flow channel area 122 that is away from the rotation direction of the flow channel assembly 12 can just pass over the connection point between the first plate 1131 and the second plate 1132 in the circumferential direction. At this time, the injection hole 112 axially opposite to the connection point between the first plate 1131 and the second plate 1132 can be connected with the hydraulic channel 121.

[0040] Therefore, the relationship between the circumferential length of the non-flow channel area 122 and the guiding inclined surface 1130 can be determined according to the actual situation. If the design process needs to be simplified, it is only necessary to set the positioning portion 123 at the circumferential center of the non-flow channel area 122 as shown in the above embodiment, and ensure that half of the circumferential length of the non-flow channel area 122 is less than the circumferential length of the guiding inclined surface 1130 defined on the first plate 1131 or the second plate 1132. It is worth noting that the design scheme mentioned here is based on the premise that the injection hole 112 is directly opposite to the connection between the first plate 1131 and the second plate 1132 in the axial direction and the first plate 1131 and the second plate 1132 are of the same size.

[0041] According to an embodiment of the utility model, the hydraulic suspension assembly 1 further includes a sealing steel ball 13, which is disposed at the injection hole 112 to selectively seal the injection hole 112. Specifically, the hydraulic suspension assembly 1 is further provided with a detachable sealing steel ball 13 at the injection hole 112, and the sealing steel ball 13 can seal the injection hole 112 after the injection is completed to prevent leakage of the damping liquid.

[0042] According to an embodiment of the utility model, the hydraulic suspension assembly 1 further includes a closing assembly 14, which is disposed on a side of the flow channel assembly 12 away from the rubber main spring 11, and the closing assembly 14 can be selectively connected to the rubber main spring 11 to fix the flow channel assembly 12. Specifically, the hydraulic suspension assembly 1 further includes a closing assembly 14 on a side of the flow channel assembly 12 away from the rubber main spring 11, and during assembly, the flow channel assembly 12 is accommodated in the accommodating cavity 111, and the closing assembly 14 is connected to the rubber main spring 11 and closes the accommodating cavity 111 to prevent the flow channel assembly 12 from falling off from the accommodating cavity 111, thereby improving the assembly stability of the flow channel assembly 12.

[0043] According to an embodiment of the utility model, the rubber main spring 11 is provided with a first clamping portion 115, and the closing assembly 14 is provided with a second clamping portion 141 suitable for clamping and cooperating with the first clamping portion 115. During assembly, the clamping of the first clamping portion 115 and the second clamping portion 141 can improve the stability of the connection between the rubber main spring 11 and the closing assembly 14, and at the same time, reduce the difficulty of assembling the closing assembly 14.
