Description

Technical Field

[0001] The invention relates to the technical field of engine driving, and in particular to an engine suspension. Background Art

[0002] In the prior art, the engine suspension system is an important part of engine application engineering. Within all engine operating speed ranges, the vibration generated by the engine must be isolated through the suspension system to minimize the vibration transmitted to the chassis and body of the vehicle. At the same time, the suspension system must also isolate the vibration of the wheel suspension system caused by uneven roads to prevent this vibration from being transmitted to the engine and avoid aggravating the engine vibration, so as to meet the stability and comfort of the vehicle during operation and ensure the stability of the engine when idling and stopping.

[0003] In order to buffer vibration, a rubber pad is usually set between the bolt assembly and the engine mounting intermediate plate to buffer the lateral displacement impact and longitudinal displacement impact of the engine mounting intermediate plate. However, due to the shearing effect of the engine mounting intermediate plate on the rubber pad, it is very easy to cause cracking and damage, thereby reducing the service life.

[0004] In order to improve the service life of the engine mount, the prior art generally adopts the method of increasing the hardness of the rubber block, such as changing the formula and process of the rubber material to increase the strength and wear resistance of the rubber block. However, although this method solves the problem of low service life, the rigidity of the product is also increased. During operation, the vibration isolation effect of the product will be reduced, thereby affecting the ride comfort and the smoothness of operation.

In this structure, the lower mounting plate 10 and the rubber body 13 placed inside the lower mounting seat 10 are usually rigid in the Z direction. In terms of structure, the upper mounting seat 11 and the mounting plate 12 have position limits, and safety is guaranteed. However, there is no strong constraint on the rubber body 13 in some directions (such as the X direction and the Y direction), and it is difficult to optimize the performance of the product in these directions. The existing structure of the engine suspension has safety hazards such as insufficient rigidity, and the suspension will be damaged after a long period of use. When replacing, the entire suspension needs to be replaced together, and the maintenance and repair costs are high.

Fig.14 This is a three-dimensional diagram of the inner frame of the first embodiment of the engine mount of the present invention. Fig.15 It is a right side view of the inner frame in the first embodiment of the engine suspension of the present invention.

[0082] like Figures 5 to 15As shown, the present invention discloses an engine mount, which includes an outer frame 20 and at least one vulcanized body 30, wherein at least one accommodating cavity 21 is arranged in the outer frame 20, and the vulcanized body 30 is detachably installed in the accommodating cavity 21. The vulcanized body 30 includes an inner frame 31 and a rubber body 32, and the rubber body 32 wraps the inner frame 31 to form an integral body. The rubber body 32 is set as a polyhedron structure, and the inner edge of the accommodating cavity 21 is a polygonal structure protruding outward, and the outer surface of the rubber body 32 matches the inner edge of the accommodating cavity 21, so that the movement of the rubber body 32 is stopped by the inner edge of the cavity.

[0083] Preferably, the outer frame 20 includes an upper mounting seat 22 and a lower mounting seat 23 that are mounted in an interlocking manner, and the accommodating cavity 21 is formed by the upper mounting seat 22 and the lower mounting seat 23. The upper mounting seat 22 and the lower mounting seat 23 can be fixedly connected by bolts 24, and the upper mounting seat 22 can also be in the form of a mounting plate that is engaged with the lower mounting seat 23.

[0084] Further preferably, the inner frame 31 may include a plurality of first frame components 311 and a first mounting portion 312, the first frame component 311 is disposed around one end of the first mounting portion 312, the rubber body 32 is vulcanized and bonded to the outside of the first frame component 311, forming a plurality of first connecting portions 321 protruding outward and distributed circumferentially along one end of the first mounting portion 312, and a stiffness adjustment structure is disposed between two adjacent first connecting portions 321, for example, in this embodiment, the stiffness adjustment structure may adopt a concave avoidance portion 322. The angle range between the first frame component 311 and the first mounting portion 312 is preferably 10°-90°. The first mounting portion 312 protrudes from the outside of the vulcanized body.

[0085] The first frame assembly 311 is provided to better form a solid whole with the rubber body 32 and the inner frame 31. For example, in this embodiment, the first frame assembly 311 and the first mounting portion 312 are vertically arranged, and multiple divergent structures are provided for greater firmness.

[0086] The cross section of the first mounting portion 312 can be a rectangular or multi-deformed solid structure. For example, in this embodiment, the cross section of the first mounting portion 312 is a pentagonal structure, which can not only save material usage, but also strengthen the entire inner frame to make it stronger.

[0087] Here, the shape of the first connection portion 321 matches the shape of the inner edge of the accommodating cavity 21 , and the thickness of the vulcanized body 30 is designed to be greater than the thickness of the accommodating cavity 21 , so that the first connection portion 321 of the rubber body 30 is interference fit with the accommodating cavity 21 .

[0088] Furthermore, the thickness of the first connecting portion 321 gradually decreases along the outward bulging direction, and a plurality of angles a (such as Figure 8 As shown in FIG. 1 , the first connecting portion 321 is interference-fitted within the corresponding angle a. The angle a preferably has an angle range of 60°-150°. A restricted area is formed within the angle a, which can be adjusted according to the interference with the vulcanized body, etc., to achieve adjustment of the stiffness in different directions.

[0089] For example, a reduction in angle a is beneficial to increasing the height in the Z direction. A reduction in the restricted area is beneficial to reducing the stiffness in the Y direction. Changes in the clearance portion have a direct impact on the stiffness in this direction. The larger the clearance portion, the smaller the stiffness. The interference between the rubber vulcanized body and the shell can also be used to adjust the product performance. The larger the interference, the greater the stiffness.

[0090] Preferably, in this embodiment, the rubber body 32 can be configured as a rectangular block symmetrically arranged up and down, with a connecting platform 323 protruding outwardly arranged between the two rectangular blocks, and a concave avoidance portion 322 located between adjacent connecting platforms 323. The avoidance portion 322 is provided to match the interference fit between the entire vulcanized body 30 and the outer frame 20, leaving a margin for the installation of the rubber body to prevent the rubber fitted in the accommodating cavity from overflowing the accommodating cavity due to extrusion. The entire rubber body is configured as a polyhedron, which greatly improves its rigidity and is more convenient for use.

[0091] In addition, the inner edge of the accommodating cavity 21 may preferably be a rectangular structure or a polygonal structure. The outer edge of the outer frame 20 is provided with a plurality of mounting holes 25 for connecting the frame. The rubber body 32 is a polyhedral structure, and the inner edge of the accommodating cavity 21 is a polygonal structure protruding outward, which is used to stop the axial movement of the rubber body.

[0092] The engine suspension of the present invention uses two mounting seats to cooperate to form an accommodating cavity, which can effectively limit the movement of the rubber body in all directions, ensure the rigidity of the entire suspension structure, have high reliability, and increase its service life.

[0093] Embodiment 2:

[0094] Fig.16 It is a top view of the second embodiment of the engine mount of the present invention. Fig.17 for Fig.16 A cross-sectional view taken along line EE in FIG. Fig.18 for Fig.16 Cross-sectional view taken along line FF. Fig.19 for Fig.16 Sectional view taken along line GG.

[0095] Fig. 20 This is a stereoscopic diagram of the rubber body in the second embodiment of the engine mount of the present invention. Fig.21This is a front view of the rubber body in the second embodiment of the engine mount of the present invention. Fig. 22 It is a side view of the rubber body in the second embodiment of the engine mount of the present invention.

[0096] like Figures 16 to 22 As shown, the structure of this embodiment is basically the same as that of the first embodiment, except that the inner frame 31 of this embodiment includes a second frame component 313 and a second mounting portion 314, the second frame component 313 is on the end of the second mounting portion 314, the rubber body 32 is vulcanized and bonded to the outer surface of the second frame component 313, and the left and right ends of the rubber body 32 are second connecting portions 324 protruding outwards respectively.

[0097] The shape of the second connection portion 324 matches the shape of the inner edge of the accommodating cavity 21 . The thickness of the vulcanized body 30 is greater than that of the accommodating cavity 21 , so that the second connection portion 324 of the rubber body 32 is interference fit with the accommodating cavity 21 .

[0098] For example, in this embodiment, the rubber body 32 is a hexahedral structure symmetrically arranged in the upper and lower parts, and the second skeleton component 313 is a rectangular plate vertically arranged on the second mounting portion 314 .

[0099] Preferably, the thickness of the second connection portion 324 gradually decreases in the direction of outward protrusion, and two angles a are formed between the inner edges of the accommodating cavity 21, and the second connection portion 324 is interference-fitted within the corresponding angles a. Here, the second connection portion 324 is preferably a conical polyhedron. The angle a is preferably in the range of 60°-150°.

[0100] A restricted area is formed within the angle a, which can be adjusted according to the interference fit with the vulcanized body, etc., to achieve adjustment of the stiffness in different directions.

[0101] For example, a reduction in angle a is beneficial to increasing the height in the Z direction. A reduction in the restricted area is beneficial to reducing the stiffness in the Y direction. Changes in the clearance portion have a direct impact on the stiffness in this direction. The larger the clearance portion, the smaller the stiffness. The interference between the rubber vulcanized body and the shell can also be used to adjust the product performance. The larger the interference, the greater the stiffness.

[0102] Further preferably, the cross section of the rubber body 32 is a hexahedral structure, and at least one stiffness adjustment structure 325 is provided at the upper end and / or the lower end of the rubber body 32. The stiffness adjustment structure 325 can preferably be provided as a corrugated groove or an arc groove with a concave middle portion. The provision of the stiffness adjustment structure 325 can effectively adjust the vertical stiffness during use and prevent the rubber body from being deformed excessively and causing failure.

[0103] In addition, the inner edge of the accommodating cavity 21 may preferably be a rectangular structure or a polygonal structure. The outer edge of the outer frame 20 is provided with a plurality of mounting holes 25 for connecting the frame. The rubber body 32 is a polyhedral structure, and the inner edge of the accommodating cavity 21 is a polygonal structure protruding outward, which is used to stop the axial movement of the rubber body.

[0104] The engine suspension of the present invention uses two mounting seats to cooperate to form an accommodating cavity, which can effectively limit the movement of the rubber body in all directions, ensure the rigidity of the entire suspension structure, have high reliability, and increase its service life.

[0105] According to the structural description of the above-mentioned embodiment 1 and embodiment 2, the engine mount of the present invention is assembled by the upper and lower mounting seats to form a containing cavity, and the formed cavity has an angle to restrict the various degrees of freedom of the vulcanized body. Among them, the angle a and the size of the restricted surface area, the interference of the exoskeleton and the vulcanized body, etc. can all be adjusted to achieve the adjustment of the stiffness in different directions, so as to obtain better comprehensive performance and meet the vibration reduction and isolation in various directions.

[0106] It is also relatively easy to adjust the product stiffness in a certain direction in the engine mount, which is conducive to modification and optimization, and can meet the vibration reduction and isolation matching of different engine systems. Generally, the vulcanized body and the accommodating area adopt interference fit, with a certain amount of compression to ensure the reliability of installation. The shape of the accommodating cavity is as close to or the same angle as the rubber surface as possible, forming multiple surfaces to fix it.

[0107] The engine mount is easy to replace, saving costs. When the elastic material ages and the performance of the product changes after a few years of use, the intermediate vulcanized body can be easily replaced. The current mounts all need to be replaced as a whole, which is cumbersome and costly. In models with high requirements for comfort, the engine mount plays a very obvious role and can achieve multi-directional vibration reduction and isolation, so that the entire engine system always maintains a good vibration reduction and isolation effect.

[0108] In summary, the engine mount of the present invention improves the suspension structure, greatly improves the service life of the motor mount, ensures the rigidity of the entire suspension structure, has high reliability, and increases its service life. The engine mount has the following advantages:

[0109] 1. Better match the stiffness in the X, Y, and Z directions to provide better vibration reduction and isolation effects.

[0110] Second, it has strong constraints on the vulcanized body, improving safety and reliability. The engine suspension adopts two mounting blocks, which cooperate to form at least one accommodating cavity, which can effectively limit the movement of the rubber body in all directions, ensure the rigidity of the entire suspension structure, high reliability, and improve the service life. It is convenient to repair and replace, and the cost is low.

[0111] 3. The engine suspension sets the outer frame and the vulcanized body as a detachable connection structure, which is convenient for separate replacement of the rubber body after it is worn during the use of the engine suspension. The structure is easy to maintain, economical and applicable, and energy-saving and environmentally friendly.

[0112] Fourth, in order to adjust the stiffness of the engine suspension, the present application is further designed with a stiffness adjustment structure, which can effectively adjust the vertical stiffness during use to prevent failure due to excessive deformation of the rubber body.

[0113] 5. The rigidity adjustment structure of the engine suspension arranged on the rubber body can also serve as a gap-avoiding part, leaving a margin for the installation of the rubber body, and preventing the rubber body fitted in the accommodating cavity from overflowing the accommodating cavity due to squeezing. By setting the entire rubber body as a polyhedron, its rigidity is greatly improved, which is more convenient for use.
