Description

Technical Field

[0001] The utility model relates to the technical field of suspension components, in particular to a suspension leather cup. Meanwhile, the utility model also relates to a suspension provided with the suspension leather cup, and a vehicle provided with the suspension. Background Art

[0002] At present, in order to improve the driving comfort of the whole vehicle, mid-range and high-end models usually use hydraulic suspension, and the hydraulic suspension generally adopts the inertial channel-decoupled membrane structure. The hydraulic suspension with this structure can better improve the high-frequency hardening phenomenon of rubber suspension and inertial channel hydraulic suspension when subjected to high frequency, improve the NVH characteristics of the whole vehicle, and keep the vehicle more comfortable during driving.

[0003] However, the current structure of hydraulic suspension has a relatively low stiffness design for the leather cup in order to improve the high-frequency vibration isolation performance of the hydraulic suspension and reduce the dynamic-static ratio. When the vehicle passes through speed bumps, washboard roads, potholes and other road conditions, the powertrain is in a low-frequency, large-amplitude condition. When the damping fluid flows from the upper liquid chamber to the lower liquid chamber through the inertial channels reserved by the upper and lower runner plates to impact the leather cup, the leather cup has a low stiffness design and low damping, and cannot effectively absorb the energy generated by the impact of the damping fluid, resulting in a large displacement of the powertrain in the height direction of the vehicle, which is prone to vibration and is transmitted to the cab, affecting the driving quality. Utility Model Content

[0004] In view of this, the utility model aims to provide a suspension leather cup to better absorb the energy generated by the large vibration of the powertrain, which can effectively improve the problem of vibration generated by the powertrain.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] A suspended leather cup, comprising a leather cup body and a frame embedded in the leather cup body;

[0007] The leather cup body is in a bowl shape, the frame is in a ring shape arranged along the circumference of the leather cup body, and the frame has a side portion arranged at the side of the leather cup body and a bottom portion arranged at the bottom of the leather cup body.

[0008] Further, the bottom portion is provided with a protrusion, which is arranged along the circumference of the frame and protrudes toward the opening side of the leather cup body; and / or,

[0009] The bottom portion is connected to the side portion in a smooth transition.

[0010] Furthermore, the top of the side portion is provided with a flange folded outwards; and / or,

[0011] The frame is made of nylon.

[0012] Furthermore, a convex column is provided at the bottom of the leather cup body, and the convex column protrudes toward the opening side of the leather cup body.

[0013] Furthermore, the boss is arranged in the middle of the bottom of the leather cup body.

[0014] Further, the bottom of the leather cup body is provided with a weakened area, and the bottom portion is arranged around the weakened area;

[0015] The weakened area is provided with a recess.

[0016] Furthermore, the recessed portions are multiple and radially arranged;

[0017] Each of the recessed portions includes a plurality of recessed pits spaced apart along the radial direction of the leather cup body.

[0018] Furthermore, the leather cup body is provided with an annular flange arranged along its edge, and the annular flange is used to be inserted into the slot of the flow channel plate.

[0019] Compared with the prior art, the utility model has the following advantages:

[0020] The suspension leather cup described in the utility model can improve its rigidity by embedding a frame in the leather cup body. When the powertrain vibrates greatly, the leather cup body is greatly deformed by the impact of the damping fluid. At this time, the frame can effectively suppress the deformation of the leather cup body, thereby increasing the damping of the suspension, and further effectively absorbing the energy generated by the vibration, reducing the movement of part of the suspension in the height direction of the whole vehicle, and effectively improving the problem of powertrain vibration.

[0021] In addition, by providing a protrusion on the bottom part along the circumference of the frame, or by smoothly transitioning the bottom part and the side part, the rigidity of the frame can be improved, thereby better suppressing the deformation of the leather cup body. The frame is made of nylon, which has the advantages of strong toughness, light weight and low cost. By providing a protrusion at the bottom of the leather cup body, the leather cup body and the flow channel plate can be effectively prevented from colliding over a large area to produce abnormal noise.

[0022] In addition, by providing a weakening area at the bottom of the leather cup body and setting a recessed portion in the weakening area, the stiffness of the middle part of the leather cup body can be reduced, thereby effectively reducing the damping of the suspension under high-frequency conditions and optimizing the high-frequency vibration of the whole vehicle. Each recessed portion includes a plurality of pits arranged at intervals along the radial direction of the leather cup body, which can further reduce the stiffness of the middle part of the leather cup body. By providing an annular flange on the leather cup body, it is convenient to connect it to the flow channel plate.

[0023] Another object of the present invention is to provide a suspension, on which the suspension leather cup as described above is provided.

[0024] In addition, the utility model also provides a vehicle, on which the suspension as described above is provided.

[0025] The vehicle and suspension described in the present invention have the same beneficial effects as the above-mentioned suspension cup relative to the prior art, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0039] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0040] The present embodiment relates to a suspended leather cup, comprising a leather cup body 1, and a frame 2 embedded in the leather cup body 1. The leather cup body 1 is bowl-shaped, the frame 2 is annularly arranged along the circumference of the leather cup body 1, and the frame 2 has a side portion 201 arranged on the side of the leather cup body 1, and a bottom portion 202 arranged on the bottom of the leather cup body 1.

[0041] The suspension cup of this embodiment can improve its rigidity by embedding the frame 2 in the cup body 1. When the powertrain vibrates greatly, the cup body 1 is greatly deformed by the damping fluid. At this time, the frame 2 can effectively suppress the deformation of the cup body 1, thereby increasing the damping of the suspension, and then effectively absorbing the energy generated by the vibration, reducing the movement of part of the suspension in the height direction of the whole vehicle, and effectively improving the problem of powertrain vibration.

[0042] Based on the above overall introduction, an exemplary structure of the suspended leather cup of this embodiment is as follows: Figures 1 to 3 As shown in the figure, the leather cup body 1 is in a bowl shape as a whole, with an opening at the top. In a natural state, the bottom part 202 of the leather cup body 1 is roughly in a flat plate shape. In addition, for the suspension leather cup as a whole, in order to facilitate its installation, as shown in the figure, Figure 1 As shown in FIG. 1 , the leather cup body 1 is provided with an annular flange 103 arranged along its edge, and the annular flange 103 is used to be inserted into the slot of the flow channel plate.

[0043] Combination Figure 3 and Figure 4As shown in , as a preferred embodiment, a protrusion 2021 is provided on the bottom portion 202, and the protrusion 2021 is arranged along the circumference of the frame 2 and protrudes toward the opening side of the leather cup body 1. By providing the protrusion 2021, the rigidity of the frame 2 can be improved, and thus the deformation of the leather cup body 1 can be better suppressed under low-frequency and large-amplitude working conditions. In addition, as Figure 3 As shown in , because the bottom portion 202 can be constructed to form a through hole, the bottom portion of the leather cup body 1 located in the through hole does not have the skeleton 2, and this portion can absorb the energy generated by the flow of the damping fluid inside the suspension when the suspension vibrates at a high frequency and a small amplitude.

[0044] In addition, still combined Figure 3 and Figure 4 As shown in , the bottom part 202 is connected to the side part 201 in a smooth transition. This setting can also improve the rigidity of the skeleton 2, and thus better suppress the deformation of the leather cup body 1. In order to further improve the rigidity of the skeleton 2, as a further implementation, the top of the side part 201 is provided with a flange 2011 folded outward. In this embodiment, as a preferred implementation, the skeleton 2 is made of nylon, which has the advantages of strong toughness, light weight and low cost, thereby reducing the suspension cost and facilitating the lightweight design of the whole vehicle. In addition, in the specific implementation, the skeleton 2 is connected to the leather cup body 1 by vulcanization.

[0045] It should be noted that in addition to the Figure 4 The frame 2 may be provided with one protrusion 2021 or may be provided with multiple protrusions 2021 and provided with radial intervals along the frame 2 according to design requirements. In addition, providing the protrusion 2021 and connecting the bottom portion 202 and the side portion 201 with a smooth transition is only a preferred implementation. In specific implementation, the bottom portion 202 may also be provided with a flat plate, that is, the protrusion 2021 is not provided, or the bottom portion 202 and the side portion 201 are not connected with a smooth transition. In addition to being made of nylon, the frame 2 may also be made of other materials such as metal. In addition, according to design requirements, the flange 2011 may not be provided on the side portion 201.

[0046] In this embodiment, as a further implementation method, Figure 1 and Figure 3As shown in , the bottom of the leather cup body 1 is provided with a convex column 101, and the convex column 101 protrudes toward the opening side of the leather cup body 1. Among them, the height of the convex column 101 is greater than the height of the leather cup body 1 corresponding to the above-mentioned protrusion 2021, so that the convex column 101 abuts against the flow channel plate to prevent the leather cup body 1 from directly colliding with the flow channel plate over a large area to produce abnormal noise. In addition, as a preferred embodiment, the convex column 101 is arranged in the middle of the bottom of the leather cup body 1 to fully ensure that under different working conditions, the convex column 101 can abut against the flow channel plate, thereby preventing the leather cup body 1 from colliding with the flow channel plate over a large area to produce abnormal noise.

[0047] Combination Figure 1 and Figure 2 As shown in , as a further embodiment, the bottom of the leather cup body 1 is provided with a weakening area, and the bottom part 202 is arranged around the weakening area, and the weakening area is provided with a recessed portion. This design can reduce the stiffness of the middle part of the leather cup body 1, thereby effectively reducing the damping of the suspension under high-frequency conditions and optimizing the high-frequency vibration of the whole vehicle. Among them, as a preferred embodiment, as Figure 2 As shown in , there are multiple recessed portions arranged radially, and the specific number thereof is not specifically limited herein.

[0048] And, if Figure 2 As shown in , each recessed portion includes a plurality of recessed pits 102 arranged at intervals along the radial direction of the leather cup body 1. In addition, since the above-mentioned convex column 101 is arranged at the middle position of the bottom of the leather cup body 1, the plurality of recessed portions are arranged radially with the convex column 101 as the center. It should be noted that the arrangement of the recessed portions and the recessed pits 102 is not limited to Figure 2 As shown in , it can be adjusted according to design requirements.

[0049] The suspension cup of this embodiment adopts the above structure. Under low-frequency and large-amplitude working conditions, when the downward movement of the suspension main spring is large, the upper liquid chamber is squeezed so that the damping fluid inside the upper liquid chamber flows into the lower liquid chamber through the inertial channel to impact the cup body 1. When the cup body 1 is impacted by the damping fluid, since the rigidity of the skeleton 2 is greater than that of the cup body 1, the energy generated by the impact of the damping fluid can be effectively absorbed, thereby reducing the movement of part of the suspension in the up and down direction of the whole vehicle and alleviating the vibration generated by the movement of the powertrain.

[0050] When the suspension vibrates at a high frequency and a small amplitude, the middle part of the suspension cup without the frame 2 will move up and down, thereby absorbing the energy generated by the flow of the damping fluid inside the suspension. In addition, the arrangement of multiple pits 102 can further reduce the high-frequency dynamic stiffness and increase the energy generated by the flow of the internal damping fluid.

[0051] In addition, this embodiment relates to a suspension, on which the suspension leather cup as above is provided.

[0052] In addition, this embodiment also provides a vehicle, on which the suspension as described above is provided.

[0053] The vehicle and suspension of this embodiment have the same beneficial effects as the above-mentioned suspension cup relative to the prior art, which will not be described in detail here.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
