Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and in particular relates to a hydraulic suspension and a vehicle. Background Art

[0002] The mount is a bidirectional vibration isolation element that connects and supports the powertrain and has a restraining and protective effect on the movement trend. The types of mounts include rubber mounts, hydraulic mounts, semi-active mounts, and active mounts.

[0003] Hydraulic mount is one of the most widely used suspension structures at present, and the longitudinal engine hydraulic mount is mostly a flanging riveted, anchor point riveted and other structures. The flanging riveted structure extends the suspension shell to the bottom and rivets the main spring, runner system, leather cup and bottom shell together. However, sufficient space must be reserved at the bottom of the suspension to meet the flanging process requirements. When the engine suspension mounting surface is too close to the vehicle frame, it is difficult to achieve riveting and liquid sealing due to the small space on the top of the engine suspension shell. Moreover, this structure that relies on riveting to fix the leather cup often finds it difficult to provide sufficient and constant pressing force to the leather cup during the bulging and contraction of the leather cup, which can easily lead to liquid leakage at the leather cup. Utility Model Content

[0004] The embodiment of the utility model provides a hydraulic mount and a vehicle, aiming to solve the problem that the hydraulic mount riveting and liquid sealing cannot be performed due to the limited installation surface of the engine mount.

[0005] In the first aspect, in order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a hydraulic mount, including:

[0006] suspending the upper housing; and

[0013] In combination with the first aspect, in one achievable manner, a positioning protrusion protruding downward is provided at the opening of the suspension upper shell, and a positioning notch adapted to the positioning protrusion is provided at the opening of the suspension lower shell.

[0014] In combination with the first aspect, in an achievable manner, the top surface of the suspended upper shell forms a first limiting surface for limiting the main spring; the lower end surface at the opening of the suspended upper shell is in contact with the upper end surface at the opening of the suspended lower shell, and the width of the lower end surface of the suspended upper shell is greater than the width of the upper end surface of the suspended lower shell, and the lower end surface of the suspended upper shell exceeds the width of the upper end surface of the suspended lower shell to form a second limiting surface for limiting the main spring.

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] Please also read Figures 1 to 6The hydraulic mount provided by the utility model is now described. The hydraulic mount comprises: an upper suspension shell 1 and a lower suspension shell 2, wherein the lower suspension shell 2 is connected to the upper suspension shell 1 through a connecting structure 3 to form a liquid seal cavity; a main spring, a flow channel skeleton and a leather cup are sequentially arranged in the liquid seal cavity from top to bottom, wherein the flow channel skeleton and the leather cup are arranged in the lower suspension shell 2; and the lower suspension shell 2 is provided with a body connection portion 21 for connecting to a body frame.

[0030] The utility model provides a hydraulic suspension, in which the structure for connecting the hydraulic suspension with the vehicle frame is arranged on the suspension lower shell 2, that is, the vehicle body connecting portion 21 extending outward from the suspension lower shell 2. At the same time, the suspension lower shell 2 and the suspension upper shell 1 are fastened together through the connecting structure 3, and the main spring, the flow channel skeleton and the leather cup are locked at the same time to realize the sealing of the hydraulic suspension.

[0031] This fastening structure can reliably fasten the suspension lower shell 2 and the suspension upper shell 1 together. The flow channel skeleton and the leather cup are arranged in the suspension lower shell 2. The bottom of the suspension upper shell 1 does not need to be provided with a flange, and does not need to be riveted. The body connection part 21 connected to the frame is arranged on the suspension lower shell 2, away from the top of the suspension upper shell 1. Therefore, it is not affected by the small space at the top of the hydraulic suspension, and the liquid seal of the hydraulic suspension can also be achieved; secondly, the suspension lower shell 2 and the suspension upper shell 1 are locked by the connecting structure 3, which can press and fix the main spring, the flow channel skeleton and the leather cup, thereby avoiding the phenomenon of liquid leakage at the leather cup due to the inconsistent pressing force during the bulging and contraction of the leather cup.

[0032] like Figure 3 and Figure 4 As shown, since the suspension upper shell 1 does not need to provide a sheltering space for the flow channel skeleton and the leather cup, the lower end of the suspension upper shell 1 does not need to be provided with a flange, and the body connection part 21 connected to the frame does not need to be provided on the suspension upper shell 1. Therefore, the size of the suspension upper shell 1 in the up and down directions is greatly reduced, and even the size along the up and down directions is smaller than the size of the suspension lower shell 2 in this direction. The suspension upper shell 1 only needs to have a lower end surface docked with the suspension lower shell 2, and the body connection part 21 is arranged at the lower end of the suspension lower shell 2, away from the top of the hydraulic suspension. A larger space is formed between the body connection part 21 and the top of the hydraulic suspension, that is, the spatial distance between the body connection part 21 and the body frame is greatly increased. Therefore, the hydraulic suspension provided in this article can be arranged in the case where the hydraulic suspension mounting surface is too close to the body frame.

[0033] Moreover, the suspension lower shell 2, as the main force of the liquid seal cavity, forms a larger cavity. Not only the flow channel skeleton and the leather cup are covered in the suspension lower shell 2, but also the lower half of the main spring is covered in the suspension lower shell 2. The volume of the suspension lower shell 2 is greater than that of the suspension upper shell 1, and therefore provides a strong structural support for the connection of the frame. At the same time, the joints between the leather cup and the flow channel skeleton and the joints between the main spring and the flow channel skeleton are all sunk below the joints between the suspension upper shell 1 and the suspension lower shell 2. Therefore, the gap where the main spring, the flow channel skeleton and the leather cup are connected perfectly avoids the joints between the suspension upper shell 1 and the suspension lower shell 2, and can avoid the problem of liquid seal leakage.

[0034] In some embodiments, Figure 3 and Figure 4 , Figure 6 As shown, a support step 26 is provided on the inner side of the suspension lower shell 2, and the flanges around the leather cup overlap the support step 26. The support step 26 supports the leather cup, and the connection structure 3 locks the suspension upper shell 1 and the suspension lower shell 2, so that the main spring is pressed against the flow channel skeleton, and the flow channel skeleton is pressed against the leather cup, which is not only reliable in locking, but also has a strong locking force that can avoid leakage when the leather cup is deformed by force.

[0035] In some embodiments, Figure 3 and Figure 4 , Figure 6 As shown, an annular groove 27 is provided on the support step 26, and an annular protrusion is provided on the flange of the leather cup to be in close contact with the annular groove 27. The annular protrusion formed by the elastic material of the leather cup is sealed in the annular groove 27 to achieve the purpose of extrusion sealing and prevent liquid from leaking from the gap between the leather cup and the flow channel frame.

[0036] In some embodiments, Figure 3 and Figure 4 As shown, there is an escape space between the bottom of the suspension lower shell 2 and the leather cup for the leather cup to bulge downward when deformed. When the leather cup is deformed and bulges downward, an escape space is provided for the deformation of the leather cup, and at the same time, the problem of collision between the leather cup and the bottom of the suspension lower shell 2 when deformed is avoided, thereby avoiding the risk of scratching the leather cup.

[0037] In some embodiments, Figures 3 to 6As shown, the outer periphery of the suspension upper shell 1 is provided with an upper ear seat 12 protruding outward, the outer periphery of the suspension lower shell 2 is provided with a lower ear seat 23 protruding outward, and the connection structure 3 is connected to the upper ear seat 12 and the lower ear seat 23. The upper ear seats 12 evenly distributed are integrally formed on the outer surface of the suspension upper shell 1, and at the same time, the lower ear seats 23 evenly distributed are integrally formed on the outer surface of the suspension lower shell 2, that is, the outer surface of the suspension upper shell 1 and the outer surface of the suspension lower shell 2 are partially protruded to form a supporting structure connected with the connection structure 3, while ensuring the reliability and firmness of the connection and locking installation of the connection structure 3, it can also reduce the material used, reduce the manufacturing cost, reduce the appearance volume, reduce the occupied space and achieve the purpose of lightweight.

[0038] Optionally, the upper ear seat 12 continuously forms a flange structure, and the lower ear seat 23 continuously forms a flange structure.

[0039] Preferably, four upper ear seats 12 and four lower ear seats 23 are respectively distributed on the suspension upper shell 1 and the suspension lower shell 2 .

[0040] In some embodiments, Figures 3 to 6 As shown, the upper ear seat 12 is provided with a connection hole 13, the lower ear seat 23 is provided with a threaded hole 24, and the connection structure 3 is a bolt that penetrates the connection hole 13 and is threadedly connected to the threaded hole 24. In this way, the suspension lower shell 2 and the suspension upper shell 1 can be fastened together by bolts, and the installation is simple and convenient, and the locking is firm.

[0041] Optionally, the threaded hole 24 is provided on the suspension upper shell 1 , while the connection hole 13 is a bare hole without a thread and is provided on the suspension lower shell 2 .

[0042] Optionally, the connection structure 3 further includes nuts that fit the bolts.

[0043] In some embodiments, Figures 4 to 6 As shown, a positioning protrusion 11 protruding downward is provided at the opening of the suspension upper shell 1, and a positioning notch 25 adapted to the positioning protrusion 11 is provided at the opening of the suspension lower shell 2. The cooperation between the positioning protrusion 11 and the positioning notch 25 provided at the same time improves the convenience of installing the suspension upper shell 1 and the suspension lower shell 2. For example, during installation, the positioning protrusion 11 is first aligned with the positioning notch 25, and then the bolts are tightened.

[0044] Optionally, the positioning protrusion 11 is provided on the suspension lower housing 2, and the positioning notch 25 is provided on the suspension upper housing 1. The suspension upper housing 1 is provided with two positioning protrusions 11; and the suspension lower housing 2 is provided with two positioning notches 25 correspondingly.

[0045] In some embodiments, Figures 4 to 5As shown, the top surface of the suspension upper shell 1 forms the first limiting surface 14 for limiting the main spring; the lower end surface of the suspension upper shell 1 opening is in contact with the upper end surface of the suspension lower shell 2 opening, and the width of the lower end surface of the suspension upper shell 1 is greater than the width of the upper end surface of the suspension lower shell 2, and the lower end surface of the suspension upper shell 1 exceeds the width of the upper end surface of the suspension lower shell 2 to form the second limiting surface 15 for limiting the main spring. The secondary limiting of the main spring by the width of the lower end surface of the suspension upper shell 1 exceeding the upper end surface of the suspension lower shell 2, and then by the tightening of the bolts, the firmness and reliability of the main spring, the flow channel frame, and the leather cup in sequence are guaranteed, and the problem of leakage in the gap between the leather cup and the flow channel frame caused by the deformation of the leather cup under force can be avoided.

[0046] In some embodiments, Figure 1 and Figure 6 As shown, a reinforcing rib 22 is provided between the body connection part 21 and the main body of the suspension lower shell 2. Since the body connection part 21 needs to be tightly connected to the vehicle frame, in order to ensure the anti-deformation performance of the body connection part 21, a plurality of reinforcing ribs 22 are provided between the main body of the suspension lower shell 2 and the body connection part 21.

[0047] The vehicle body connecting portion 21 is provided with mounting holes for connecting to the vehicle frame.

[0048] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0049] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, comprising the hydraulic suspension.

[0050] In the vehicle provided by the embodiment of the utility model, since the upper suspension shell 1 and the lower suspension shell 2 are locked by the connection structure 3, the lower end of the upper suspension shell 1 does not need to be provided with a flange, and the lower suspension shell 2 can be prevented from loosening. Therefore, it can not only achieve liquid sealing when the space at the top of the engine hydraulic suspension is too small, but also avoid the phenomenon of leather cup leakage, thereby improving customer perceived satisfaction.

[0051] 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 and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
