Description

Technical Field

[0001] The utility model relates to the technical field of automobile suspension structures, in particular to a hydraulic suspension device for an automobile engine. Background Art

[0002] The suspension is one of the components used to reduce the vibration of the automobile engine, and plays a key role in reducing noise and improving the ride comfort of the vehicle. At present, there are two common suspension devices, namely rubber suspension devices and hydraulic suspension devices.

[0003] Because the hydraulic suspension device combines the characteristics of rubber damping and liquid damping, it uses the elasticity of rubber elements and the relatively large damping and stiffness characteristics generated when the liquid flows through the flow channel to weaken the low-frequency vibration of the powertrain in the low-frequency stage, and has relatively small damping and stiffness characteristics in the high-frequency stage to reduce the vibration transmission rate and noise effect. Therefore, its elasticity and damping properties are generally better than ordinary rubber suspension devices, and it has gradually been more widely used.

[0004] The leather cup installed on the hydraulic suspension device mainly plays the role of transmitting pressure and sealing. During vehicle evaluation, the leather cup is easily affected by the gravity of the engine and becomes dented, which may be mistaken by the evaluators as a product defect. In daily use of the vehicle, the leather cup is also more prone to wear and deformation than other parts on the hydraulic suspension device.

[0005] In order not to affect the technical effect of the hydraulic mount, the worn leather cup must be repaired and replaced. However, it is relatively troublesome to replace the leather cup alone. At the same time, compared with the rubber mount, the hydraulic mount structure is relatively complex, and its material cost, R&D experimental cost and manufacturing cost are higher than those of the rubber mount. Therefore, it is too expensive to replace the entire hydraulic mount. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a hydraulic suspension device for an automobile engine, which is used to solve the problem that the leather cup of the hydraulic suspension in the prior art is difficult to replace or the replacement cost is high after it is deformed and worn due to defects such as engine gravity.

[0007] To achieve the above-mentioned purpose and other related purposes, the utility model provides a hydraulic suspension device for an automobile engine, comprising a base, a damping component, a leather cup and a shell installed on the base, the damping component is sealed inside the shell by the leather cup, a sheath is detachably installed on the shell, and the sheath wraps around the leather cup; a convex buckle is provided on the outer wall of the shell, and a buckle groove is provided on the inner wall of the sheath; the sheath is put on the shell, and the convex buckle and the buckle groove are interference fit; a sliding groove is provided on the inner wall of the sheath, and the sliding groove extends to the bottom of the sheath; the sheath is put on the shell, and the convex buckle slides along the sliding groove into the buckle groove.

[0008] Optionally, there are three protruding buckles, three corresponding buckle grooves, and three sliding grooves.

[0009] Optionally, the shape of the slide groove is a right angle.

[0010] Optionally, the slide groove is in a spiral shape.

[0011] Optionally, the buckle groove is a through groove; the slide groove is a through groove.

[0012] Optionally, the sheath is made of elastic material.

[0013] Optionally, the sheath is made of rubber.

[0014] As described above, the hydraulic suspension device of an automobile engine of the utility model has at least the following beneficial effects:

[0015] 1. The hydraulic suspension device of the automobile engine is provided with a sheath detachably mounted on the outer shell. The design of the sheath covering the leather cup prevents the leather cup from being directly affected by the gravity of the engine. The adverse effect of the gravity of the engine in the prior art applied to the leather cup is borne by the sheath. When the sheath is deformed or damaged, the operator only needs to remove the old sheath and replace it with a new one. The price of a single sheath is relatively low compared to the entire hydraulic suspension device, which solves the problem in the prior art that the leather cup of the hydraulic suspension is difficult to replace or the replacement cost is high after being deformed and worn due to the gravity of the engine.

[0016] 2. The hydraulic suspension device of the automobile engine is designed with a convex buckle on the outer wall of the shell and a buckle groove on the inner wall of the sleeve. Compared with the design in which the entire inner wall of the sleeve and the entire outer wall of the shell are interference fit, when the sleeve is put on the shell, only the convex buckle and the buckle groove are interference fit, which is more convenient for operators to install or remove the sleeve.

[0017] 3. The hydraulic suspension device of the automobile engine is designed with a slide groove on the inner wall of the jacket, which further improves the convenience of installing the jacket on the outer shell and improves the maintenance convenience of the entire vehicle.

[0018] 4. The hydraulic suspension device of the automobile engine is designed with both the buckle groove and the slide groove being through grooves, which is more conducive to the cutting of the tool during the processing of the sheath, improves the processing efficiency of the sheath, and reduces the processing cost of the sheath.

[0023] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0024] See also Figure 1 to Figure 2 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0025] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0026] See also Figure 1The utility model provides a hydraulic suspension device for an automobile engine, comprising a base 1, a damping component, a leather cup 2 and a shell 4 mounted on the base 1. The base 1 is used to fix the hydraulic suspension device in the engine compartment of the automobile. The designer may also set a bracket 3 on the shell 4 to fix the position of the hydraulic suspension device as needed. The specific structure and installation method of the base 1 and the bracket 3 are not described in detail here. Similarly, the internal structure of the damping component is not the focus of this specification, and is not described in detail here.

[0027] like Figure 2 As shown, the damping component is sealed inside the shell 4 by the leather cup 2, and the leather cup 2 plays the role of transmitting pressure and sealing. The main point of this specification is that the shell 4 is detachably mounted with a sleeve 5, and the sleeve 5 covers the leather cup 2. The hydraulic suspension device of the automobile engine is detachably mounted with a sleeve 5 on the shell 4, and the sleeve 5 covers the leather cup 2, so that the leather cup 2 is prevented from being directly affected by the gravity of the engine. The adverse effect of the gravity of the engine in the prior art applied to the leather cup 2 is borne by the sleeve 5, and when the sleeve 5 is deformed or damaged, the operator only needs to remove the old sleeve 5 and replace it with a new sleeve 5. The price of a single sleeve 5 is relatively low compared to the entire hydraulic suspension device, which solves the problem that the leather cup 2 of the hydraulic suspension in the prior art is difficult to replace or the replacement cost is high after being deformed and worn due to the gravity of the engine.

[0028] In another embodiment, see Figure 2 The inner wall of the sheath 5 is sleeved on the outer wall of the shell 4 with interference fit, thereby ensuring that the sheath 5 can be firmly installed on the shell 4. However, the interference fit brings inconvenience to the installation work of the operator. The following will provide a more optimized matching structure of the sheath 5 and the shell 4.

[0029] In another embodiment, see Figure 2 , a convex buckle 41 is provided on the outer wall of the shell 4, and a buckle groove 51 is provided on the inner wall of the sleeve 5; the sleeve 5 is put on the shell 4, and the convex buckle 41 and the buckle groove 51 are interference fit. The hydraulic suspension device of the automobile engine is designed by providing a convex buckle 41 on the outer wall of the shell 4 and a buckle groove 51 on the inner wall of the sleeve 5. Compared with the design in which the entire inner wall of the sleeve 5 and the entire outer wall of the shell 4 are interference fit, when the sleeve 5 is put on the shell 4, only the convex buckle 41 and the buckle groove 51 are interference fit, which is more convenient for operators to install or remove the sleeve 5.

[0030] In another embodiment, see Figure 2A slide groove 52 is provided on the inner wall of the sleeve 5, and the slide groove 52 extends to the bottom of the sleeve 5; the sleeve 5 is put on the shell 4, and the convex buckle 41 slides into the buckle groove 51 along the slide groove 52. The hydraulic suspension device of the automobile engine is designed with a slide groove 52 on the inner wall of the sleeve 5. When the operator performs the installation operation, the slide groove 52 can be gradually installed along the convex buckle 41 until the convex buckle 41 is buckled into the buckle groove 51, which further improves the convenience of installing the sleeve 5 on the shell 4 and improves the maintenance convenience of the entire vehicle.

[0031] In another embodiment, see Figure 1 and Figure 2 The shape of the slide groove 52 is a right angle. When the operator installs the cover 5, he first aligns the vertical slide groove 52 with the convex buckle 41, puts the cover 5 downward, and then rotates the cover 5 to buckle the convex buckle 41 and the buckle together, so that the cover 5 is firmly installed on the shell 4.

[0032] In another embodiment, the shape of the slide groove 52 is spiral, that is, the slide groove 52 is a spiral groove along the outer wall of the shell 4. When the operator installs the sheath 5, he directly aligns the bottom opening of the slide groove 52 with the convex buckle 41, and then rotates the sheath 5 until the convex buckle 41 and the buckle groove 51 are buckled together, and the sheath 5 is firmly installed on the shell 4. This embodiment and the previous embodiment only exemplify two shapes of the slide groove 52, and the designer can also design other shapes of the slide groove 52 according to actual needs.

[0033] In another embodiment, see Figure 2 The buckle groove 51 is a through groove, and the slide groove 52 is a through groove. The hydraulic suspension device of the automobile engine is designed with the buckle groove 51 and the slide groove 52 both being through grooves, which is more conducive to the tool movement during the processing of the sheath 5, improves the processing efficiency of the sheath 5, and reduces the processing cost of the sheath 5.

[0034] In another embodiment, see Figure 2 There are three convex buckles 41, three corresponding buckle grooves 51, and three slide grooves 52. When the sheath 5 is mounted on the shell 4, the three convex buckles 41 slide into one slide groove 52, and then each is interference fit with a buckle groove 51. Compared with the structure of one or two convex buckles 41, the sheath 5 can be more firmly mounted on the shell 4; and according to geometric knowledge, three points determine a plane, and the three buckle grooves 51 each cooperate with a convex buckle 41, which is equivalent to three points where the sheath 5 and the shell 4 limit each other. The three points of mutual limitation are sufficient to firmly mount the sheath 5 on the shell 4, and there is no need to spend more cost to produce the shell 4 with 4 or more convex buckles 41 and the sheath 5 with 4 or more buckle grooves 51, thereby saving production cost.

[0035] In other embodiments, Figure 1 As shown, the sheath 5 is made of an elastic material, such as rubber or elastic plastic. The sheath 5 is made of an elastic material. No matter which detachable method of the above-mentioned embodiment is selected, it is easier for operators to install and disassemble it compared to non-elastic materials.

[0036] In summary, the utility model is designed that the sheath 5 is detachably mounted on the shell 4, and the sheath 5 covers the leather cup 2, so that the leather cup 2 is prevented from being directly affected by the gravity of the engine. The adverse effect of the gravity of the engine in the prior art on the leather cup 2 is borne by the sheath 5, and when the sheath 5 is deformed or damaged, the operator only needs to remove the old sheath 5 and replace it with a new one. The price of a single sheath 5 is relatively low compared to the entire hydraulic suspension device, which solves the problem that the leather cup 2 of the hydraulic suspension in the prior art is deformed and worn due to the gravity of the engine. The problem of being difficult to replace or having high replacement costs after defects such as the above is solved; at the same time, the outer wall of the shell 4 is provided with a convex buckle 41, and the inner wall of the sheath 5 is provided with a buckle groove 51. Compared with the design that the entire inner wall of the sheath 5 and the entire outer wall of the shell 4 are interference fit, when the sheath 5 is put on the shell 4, only the convex buckle 41 and the buckle groove 51 are interference fit, which is more conducive to the installation or removal of the sheath 5 by the operator; and the design that the inner wall of the sheath 5 is provided with a slide groove 52 further improves the convenience of installing the sheath 5 on the shell 4, and improves the maintenance convenience of the entire vehicle. Therefore, the utility model effectively overcomes the shortcomings of the prior art and has a high industrial utilization value.

[0037] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
