Description
Technical Field
The invention relates to an automobile suspension device, a forming die and a forming method of the suspension device, in particular to a double-layer vibration isolation suspension, a forming method of the double-layer vibration isolation suspension and a forming device of the double-layer vibration isolation suspension.
Background
Suspensions are automotive power assemblies used in the current automotive industry to reduce and control the transmission of engine vibrations and to provide support. In the current automobile industry, widely used suspensions are classified into conventional pure rubber suspensions, hydraulic suspensions with better dynamic and static performances, and the like, such as rubber suspensions, hydraulic suspensions, air suspensions, and the like. The pure rubber suspension generally consists of a rubber bushing (or other vulcanized parts) and a bracket, while the hydraulic suspension also comprises a special liquid (generally ethylene glycol) filled in the hydraulic suspension besides a rubber main spring, and the hydraulic suspension is formed in a certain structure through parts such as a runner plate, a decoupling sheet, a leather cup and the like.
Due to the upgrading of the consumption of the automobile market, the performance requirements of the vehicles are higher and higher by customers, but due to the fact that the starting torque of the driving motor of a high-end new energy vehicle is larger and larger, the suspension serving as a part system for isolating the Vibration between the driving motor and the vehicle body faces a new challenge, and the contradiction between the durability and the NVH (Noise, Vibration and Harshness) is deeper and deeper.
Most of the existing suspension products are made of cast aluminum materials, the weight is heavier, and the demand for light weight is increasingly strong due to the demand of customers for endurance mileage. The current suspension design basically adopts cast aluminum materials, and light-weight means need to be found aiming at the development of electric vehicle chassis parts.
On the other hand, the mainstream of the current automobile has entered the era of new energy vehicles. The excitation of the electric vehicle is different from the excitation of the traditional internal combustion engine, so that the design of a suspension structure of the electric vehicle is more suitable, and for the excitation of the motor, the NVH performance of the existing suspension product made of aluminum can not be further improved under certain working conditions.
The existing process for suspending the product by using the cast aluminum material can be simply and generally described as the following three steps:
step one, casting aluminum liquid to form a suspension bracket;
vulcanizing rubber into a bushing;
and step three, pressing the bush into the suspension bracket made of the cast aluminum material through a press.
However, the existing processing technology is directed to cast aluminum materials (or other metal materials) as the suspension bracket, and is characterized in that the metal materials have higher strength as the suspension bracket, but correspondingly, the self weight of the metal materials is larger, and the suspension bracket made of the metal materials can make the suspension "hard", and has no advantage in NVH performance such as vibration and noise filtration. If the material of the suspension bracket changes, especially when the suspension bracket does not adopt a metal material with higher strength, the existing processing technology cannot be generally used on other materials.

Detailed Description
The technical solution in the embodiments of the present invention will be further clearly and completely described below with reference to the accompanying drawings and embodiments. It is obvious that the described embodiments are used for explaining the technical solution of the present invention, and do not mean that all embodiments of the present invention have been exhaustively exhausted.
Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Referring to fig. 1 and 2, in a first aspect of the present invention, a double-layer isolation mount is disclosed, and its main structure includes a large bushing 1, a bushing inner core 2, a mount bracket 3, a small bushing 4, and a positioning hole 5. The double layer isolation mount is used to connect the motor and the vehicle frame, in particular to the vehicle frame through the large bushing 1 and to the motor through the small bushing 4 (or vice versa). According to the invention, the two ends of the suspension bracket 3 are respectively provided with the bushing vibration isolation mechanisms, so that the double-layer vibration isolation function of the whole suspension is realized.
As a preferred embodiment of the present invention, the double-layer vibration isolation suspension may be directly or indirectly connected to the motor, may be directly fixed to a housing of the motor, or may be indirectly connected to a fixing structure or a buffering structure on the periphery of the motor, which all belong to one of multiple connection modes of the double-layer vibration isolation suspension. On the other hand, the large bushing 1/the small bushing 4 are fixedly connected to the vehicle frame/the motor, so that the double-layer vibration isolation suspension is respectively connected to the motor and the vehicle frame to form a physical partition, thereby isolating the shaking of the motor to the vehicle body and limiting the displacement of the motor movement through the mutual cooperation of the suspension bracket 3, the large bushing 1 and the small bushing 4. It will be appreciated by those skilled in the art that the above-described connection of the suspension bracket 3, the large bushing 1 and the small bushing 4 is only one of many connections of the present invention, and in other embodiments consistent with the present invention, one of the large bushing 1 and the small bushing 4 may be connected to an associated structure associated with the motor, and one of the large bushing 1 and the small bushing 4 may also be connected to an associated structure associated with the vehicle frame.
As shown in fig. 1 and 2, the small bush 4 and the large bush 1 are each of a cylindrical structure. The suspension bracket 3 is roughly triangular, three corners of the triangle are processed in an arc shape, one edge of the triangle is provided with a plurality of small bushings 4, the small bushings 4 are used for fixing the suspension bracket 3 with a motor, and the side surface of the suspension bracket 3 is also provided with a positioning hole 5 for positioning and demoulding. One end of the triangular shape of the suspension bracket 3, i.e. the other end remote from the three small bushings 4 shown in fig. 1, 2, has a bushing cavity. The bushing cavity occupies about 1/3 of the area of the suspension bracket 3, as opposed to the location of the small bushing 4. The large bushing 1 is arranged in the bushing cavity, and a bushing inner core 2 is further arranged in the center of the large bushing 1.
As a preferred embodiment of the present invention, the positioning hole 5 has a hemispherical shape. In the actual assembly process of the double-layer vibration isolation suspension, the double-layer vibration isolation suspension is combined with the hemispherical positioning pin 6.52 on the assembly trolley in a workshop, so that the position of the whole motor assembly can be accurately determined through the double-layer vibration isolation suspension, and the convenience and the accuracy of the assembly of the motor assembly are ensured.
The suspension bracket 3 shown in fig. 1 and 2 is provided with three small bushings 4, each small bushing 4 has a cylindrical outer edge, and a through hole is reserved in the middle of the cylindrical outer edge. In particular, as shown in fig. 1, the upper surfaces of the three small bushings 4 are slightly lower than the upper surface of the suspension bracket 3, forming a slightly downwardly concave structure, which can more conveniently fix a fixing member therein, such as a screw, a nut, or other forms of fixing members.
It will be understood by those skilled in the art that fig. 1 and 2 show the construction of a suspension bracket 3 with three small bushings 4, but the present invention is not limited thereto. In other embodiments of the invention, the number of small bushings 4 is variable, including but not limited to two, four or other reasonable numbers, which can achieve the objectives of the invention. On the other hand, the suspension bracket 3 serves to connect the motor and to accommodate the large and small bushings 1, 4, and thus its shape is not limited to the triangle-like shape as shown in fig. 1 and 2. In other embodiments of the present invention, the suspension bracket 3 may also be rectangular, semicircular or other reasonable shapes, which can achieve the technical purpose of the present invention and achieve the technical effect of the present invention.

The feeding inner opening 6.4 (injection molding opening) is arranged on the side surface of the cavity area 6.10, and the feeding inner opening 6.4 is communicated with the cavity area 6.10. In the injection molding process, the nylon-glass fiber mixture flows into the cavity area 6.10 through the feeding inner opening 6.4, so that the suspension bracket 3 is molded in the cavity area 6.10.
Continuing as shown in fig. 4, the base 8 and the lower stage body 6.1 forming the lower cavity 6 are both square parts, and the four corners of the lower stage body 6.1 are provided with lower cavity mounting holes 6.7. Lower cavity mounting posts 6.9 are fixed in lower cavity mounting holes 6.7 so that lower stage body 6.1 is mounted on base 8 and the four corners of lower stage body 6.1 are aligned with the four corners of base 8. Lower die cavity installation pillar 6.9 is the cylinder, and its bottom fixed mounting is in 8 four corners of base, and 8 four corners of base are a little higher than 8 whole upper surfaces of base.

Therefore, the lower cavity spring support 6.8 can play a role in buffering the whole lower rack body 6.1. In a preferred embodiment of the invention, the lower part of the lower cavity spring support 6.8 is a spring, the middle part is a support column with a larger diameter, and the upper part is a support column with a smaller diameter. The lower spring is arranged on the base 8, and the height of the base 8 is slightly lower than the whole upper surface of the base 8. The upper support column is connected to the lower stand body 6.1.
The lower cavity water cooling pipes 6.6 are arranged at the bottom of the lower rack body 6.1, and as shown in fig. 4, a plurality of lower cavity water cooling pipes 6.6 arranged in parallel traverse the bottom of the whole lower rack body 6.1.

Fig. 6 shows a specific structure of the positioning feature forming mechanism 6.5. As shown in fig. 6, the positioning feature forming mechanism 6.5 is mainly composed of a bottom slide 6.51 and a positioning pin 6.52. The bottom slide 6.51 is an overall rectangular module which can slide on the lower stand body 6.1 shown in fig. 4 in a direction towards/away from the cavity area 6.10. The positioning pin 6.52 comprises a protruding tip which is fixed to the upper surface of the bottom slider 6.51 by means of a substantially trapezoidal fixing member. In the structure shown in fig. 4, a handle is further provided outside the bottom slider 6.51 and outside the lower rack body 6.1. In operation, the handle can pull the bottom slider 6.51 to move away from the cavity area 6.10 (i.e., in the direction of the arrow in fig. 6), thereby facilitating the removal of the locating pin 6.52 of the locating feature forming mechanism 6.5 from the cavity area 6.10.
The positioning feature forming mechanism 6.5 has the functions of: due to the positioning design of the suspension bracket 3, the requirement of the cavity area 6.10 on the position is high, and the suspension bracket 3 is not easy to demould after being formed. Therefore, the positioning feature forming mechanism 6.5 of the present invention is designed with a bottom slider 6.51 that can slide in the Z-plane direction (i.e. on the surface of the lower stage body 6.1), thereby facilitating the demolding of the suspension support 3.
As shown in fig. 5, in the molding of the upper cavity 7, the upper rack 7.1 has a square structure, and the molding of the upper cavity 7 and the molding of the lower cavity 6 are the same in size. During installation, an upper rack body 7.1 for forming the upper cavity 7 is installed on a lower rack body 6.1 for forming the lower cavity 6 through an upper cavity installation pillar 7.4.
Continuing with fig. 5, an upper cavity mounting post 7.4 is provided at the top of the lower cavity mounting post 6.9, and the diameter of the upper cavity mounting post 7.4 is slightly smaller than the diameter of the lower cavity mounting post 6.9. As a preferred embodiment of the present invention, the diameter of the upper cavity mounting pillar 7.4 is slightly smaller than the diameter of the lower cavity mounting pillar 6.9, so that the bottom of the upper cavity mounting pillar 7.4 is embedded into the top of the lower cavity mounting pillar 6.9, and the joint between the two is also the position of the lower cavity mounting hole 6.7. Such a nesting arrangement enables the upper and lower cavity mounting posts 7.4, 6.9 to be more securely mounted within the lower cavity mounting apertures 6.7. It will be appreciated by those skilled in the art that the above configuration and selection of the diameters of the upper and lower cavity mounting posts 7.4, 6.9 is only one of many embodiments of the invention and is not intended to limit the invention. In other embodiments of the present invention, the upper cavity mounting pillar 7.4, the lower cavity mounting pillar 6.9 and the lower cavity mounting hole 6.7 may have other connection relationships, and the present invention is not limited thereto.
Continuing with FIG. 5, an upper cavity spring support 7.3 is provided at the top of the lower cavity spring support 6.8 and is generally hat shaped for securing the top of the lower cavity spring support 6.8 to the upper stage body 7.1. Through the cooperation of the upper cavity spring support 7.3 and the lower cavity spring support 6.8, the lower cavity spring support 6.8 can simultaneously provide elastic support for the upper rack body 7.1 and the lower rack body 6.1.
Referring to fig. 4 and 5, the locating feature forming mechanism 6.5 is disposed behind the lower stage body 6.1, and has a locating feature forming mechanism fixing post 7.2 at an upper portion thereof, and the locating feature forming mechanism fixing post 7.2 penetrates through a surface of the upper stage body 7.1 so that the locating feature forming mechanism 6.5 can be fixed inside the forming lower cavity 6. During the injection molding process of the suspension bracket 3, the liquid nylon-glass fiber mixture is poured into the cavity area 6.10, and at this time, the liquid mixture will generate an outward pushing force, i.e., a direction indicated by an arrow in fig. 6, on the originally positioned positioning feature forming mechanism 6.5. However, the locating feature forming mechanism 6.5 does not need to be moved during the injection moulding process, but rather needs to be slid away from the cavity area 6.10 after the injection moulding process is completed. Therefore, the positioning feature forming mechanism fixing strut 7.2 is used for keeping the position of the positioning feature forming mechanism 6.5 from changing in the injection molding process of the nylon-glass fiber mixture, so that the positioning pin 6.52 of the positioning feature forming mechanism 6.5 can form the positioning hole 5 of the suspension bracket 3.
Referring back to fig. 3, the top mount 9 is also a square member that is sized and shaped to mate with the base 8 and to correspond to an inverted base when installed. The footstock 9 is arranged at the top of the upper cavity mounting pillar 7.4, and the footstock 9 is provided with a feeding outer opening 9.1. The feeding outer opening 9.1 of the top seat 9 is communicated with the feeding inner opening 6.4 of the lower molding cavity 6 through a pipeline, so that the liquid nylon-glass fiber mixture is led in from the outside through the feeding outer opening 9.1 and is communicated with the feeding inner opening 6.4 through the pipeline, and finally flows into the cavity area 6.10. The selection of the positions of the feeding outer opening 9.1 and the feeding inner opening 6.4 is determined through a multi-wheel mold flow analysis result, so that the distribution of the nylon-glass fibers in the suspension bracket 3 is ensured to be more beneficial to the structural strength of the suspension bracket 3. In one embodiment of the present invention, the feed inlet 9.1 is disposed at the center of the top seat 9, but the present invention is not limited thereto.
Referring to fig. 7, in addition to the above-mentioned double-layer isolation mount and its forming device, a third aspect of the present invention further discloses a forming method of the double-layer isolation mount. The core idea of the method of the invention is that: because the thin edge of the nylon material is easy to crack slightly when the nylon material is subjected to internal pressing force, and the thin edge is easy to deform by extrusion, the invention adopts a molding process that the lining is vulcanized firstly and then is placed into the nylon material injection mold to be integrally molded.
The core idea of the method of the invention is mainly realized by the following process steps:
s1: the small bush 4 and the large bush 1 of rubber material are vulcanization molded. In a preferred embodiment of the present invention, the small bush 4 and the large bush 1 are formed in a cylindrical structure, but the present invention is not limited thereto, and other reasonable shapes can be used as the structure of the small bush 4 and the large bush 1. Referring to the structure of the double-deck isolation mount shown in fig. 1 and 2, step S1 vulcanizes three small bushings 4 and one large bushing 1.
S2: a liner core 2 is embedded in the large liner 1. As an embodiment of the present invention, the liner core 2 may be made of aluminum, or may be made of other reasonable materials, and the present invention is not limited thereto. Since the lining core 2 is nested in the large lining 1 made of rubber material, and the rubber material has certain elasticity and ductility, the combination of the large lining 1 and the lining core 2 can adopt an extrusion process.
S3: the small liner 4 and the large liner 1 with the liner core 2 are coated with an adhesive on their sides. As an embodiment of the invention, the large rubber bushing 1 is made of natural rubber materials and is designed by adopting the inner diameter of a cross-shaped bushing. A circle of nylon sleeve is designed outside the large bushing 1, and the surface of the nylon sleeve can be well combined with the adhesive. The small bush 4 may not have a nylon material sleeve on the surface, but the small bush 4 is also designed to be well bonded with the adhesive. The side surfaces of the small bush 4 and the large bush 1 coated with the adhesive are the connecting surfaces of the small bush 4, the large bush 1 and the suspension bracket 3.
Those skilled in the art will appreciate that steps S2 and S3 are both preparation steps for the large bush 1 and the small bush 4, and therefore the order of steps S2 and S3 in operation may be interchanged.
S4: the small adhesive-coated liner 4 and the large liner 1 with liner core 2 are each placed in the cavity area 6.10 of the molding apparatus. Referring to the molding apparatus shown in fig. 4, in this step, the large liner 1 with the liner core 2 coated with an adhesive is placed in the large liner placing area 6.2, and the small liner 4 coated with an adhesive is placed in the small liner placing area 6.3.
S5: before the nylon-glass fiber mixture is injected, a positioning feature forming mechanism 6.5 is arranged in the forming device, the suspension positioning feature forming mechanism 6.5 is pushed to a correct position (namely, a positioning pin 6.52 of the positioning feature forming mechanism 6.5 enters a cavity area 6.10), then the formed upper cavity 7 and the formed lower cavity 6 are closed together, so that the suspension bracket 3 is injection-molded in the cavity area 6.10, and a positioning hole 5 is formed in the injection molding process.
It will be appreciated by those skilled in the art that steps S4 and S5 are preparatory steps for the large/small bushing and locating feature shaping mechanism 6.5, respectively, and thus the order of preparatory steps for the locating feature shaping mechanism 6.5 of steps S4 and S5 (i.e., pushing the suspended locating feature shaping mechanism 6.5 into position) may be interchanged in operation.
S6: melting the nylon-glass fiber to liquid state at high temperature according to a certain proportion. In a preferred embodiment of the present invention, the nylon-glass fiber is made of PA66 (Polyamide 66, nylon 66) and glass fiber. The invention selects a proper nylon-glass fiber ratio based on the CAE analysis result, and because the suspension bracket 3 needs to bear a larger load, the suspension bracket 3 selects PA66 (nylon 66) and 50% glass fiber, namely the ratio of the nylon and the glass fiber is 1: 1.
It will be appreciated by those skilled in the art that the nylon-fiberglass formulation is only one of many alternatives and is not intended to be limiting. In other embodiments of the invention, the nylon and the glass fiber can adopt other reasonable proportions, and the technical purpose of the invention can be realized to achieve the technical effect of the invention.
S7: and injecting the liquid nylon-glass fiber mixture which is melted at high temperature into the cavity area 6.10 through the feeding inner opening 6.4 of the forming device, filling the whole cavity area 6.10, and performing injection molding on the suspension bracket 3. The nylon-fiberglass hybrid material will flow through the internal channel into the feed inlet 6.4 (i.e., the injection port) in the mold.
Specifically, with reference to the configuration of the molding apparatus shown in fig. 3-6, the nylon-fiberglass mixture is introduced from the outside through the feed outer port 9.1, is communicated through a conduit to the feed inner port 6.4, and finally flows into the cavity area 6.10. The liquid nylon-glass fiber mixture enters the cavity area 6.10 of the forming device through the feeding inner opening 6.4 (injection molding opening), so that the liquid nylon-glass fiber mixture wraps the small lining 4 and the side face of the large lining 1 with the lining inner core 2 in the forming device.
In one embodiment of the present invention, the injection pressure of the suspension bracket 3 is preferably 90 to 120Mpa during injection molding. The pressure maintaining time of the mold in the injection molding process is preferably 8-10 s, and the injection molding temperature inside the mold is controlled to be about 90 ℃. However, it will be understood by those skilled in the art that the present invention is not limited thereto.
S8: after the suspension support 3 is injection molded, the upper molding cavity 7 and the lower molding cavity 6 are opened, the molded whole double-layer vibration isolation suspension is taken out, and the whole double-layer vibration isolation suspension is cooled by air cooling.
The existing process for suspending the product by using the cast aluminum material comprises the following steps: the aluminum liquid is cast into the suspension bracket 3/rubber vulcanization lining which is pressed into the corresponding position of the suspension bracket 3 through a press.
However, unlike the prior art, the nylon/glass fiber material adopted by the invention cannot bear the interference pressure generated when the liner is pressed in. Therefore, the suspension made of the nylon and glass fiber materials needs a completely different forming method, namely the double-layer vibration isolation suspension cannot adopt the forming and processing method of the existing cast aluminum material suspension.
If the nylon and glass fiber suspension bracket 3 adopts the same method of cast aluminum suspension, the suspension bracket 3 has great damage risk when the large bushing 1 and the small bushing 4 are pressed in, and the finished product rate of the double-layer vibration isolation suspension of the invention reaches more than 95 percent by adopting the forming method of the invention.
On the other hand, the existing processing technology of the cast aluminum suspension cannot adopt the method of the invention. This is because the melting point of aluminum is much higher than that of rubber, so when rubber is vulcanized and molded in advance and aluminum liquid is poured, the rubber is melted and deformed again by the aluminum liquid, and the integral molding of suspension cannot be realized.
Fig. 8 compares the acceleration measured in the x, y, z directions of the two suspensions on the chassis at idle for the double layer isolation mount of the present invention and a conventional aluminum suspension. Referring to fig. 8, the double-layer vibration isolation suspension is manufactured by adopting a nylon and glass fiber material structure, and can generate larger damping compared with the conventional suspension structure made of cast aluminum material. Test results show that under the same working condition, the vibration intensity of the double-layer vibration isolation suspension is reduced by 20-30%. In addition, because the excitation of the electric vehicle is more concentrated on a high-frequency stage, the double-layer vibration isolation suspension adopts the material of nylon and glass fiber, so that the mode of the suspension bracket can be reduced to a certain degree, and the resonance frequency is avoided.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above described embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
