Description

DESCRIPTION A BALANCE BAR BUSH Technical Area The balance bar in the suspension structure, which determines the road holding and driving behavior of the invention vehicles. which prevents the transmission of vibrations formed here to the vehicle body by bearing, relates to a suspension element having torsional and vibration damping properties.

More specifically, it is an important issue for the independent suspension systems found in current invention vehicles. It will form here by surrounding the anti-roll bar, which is an element, with a rubber body. It provides driving comfort by preventing the transmission of vibrations to the vehicle body and the vehicle's handling. relates to a balance bar sign that helps his behavior.

State of the Art The anti-roll bar is used to drive around corners that a vehicle may encounter while traveling. and it is a suspension unit in which the negative effects that may be transmitted to the passengers are eliminated. A On the other hand, while the vehicle continues its course safely without skidding, vibrations are prevented from reaching the vehicle body. For this suspension By using elastomer bushings in their structures, vibrations occurring in these areas are dampened.

Said elastomer bushings find a very wide usage area in the vehicle. a comfortable flock in parts such as the stabilizer bar and the lower chassis or control arms in the vehicle body to provide They have supporting functions such as damping the vibrations that occur or preventing the transmission of sound.

Thus, the main purpose of the bush is to dampen the vibrations coming from the road and to go to the vehicle cabin. is to be prevented. The anti-roll bar, which can be described as a torsion bar, helps the vehicle in corners. In all cases, the vehicle wheels must touch the ground in order to compensate for the side rolls caused by the skidding. it provides. Thus, in order for the signs to exhibit these behaviors expected of them, the vehicle is driven. be resistant to all challenging physical conditions such as torsion and compression that may occur while in motion, and should be able to fulfill these functions for a long time.

When a bushing surrounds the balance bar to be installed, the balance bar is inside the bushing. It is of great importance to keep the amount of jamming under control and at the desired level. Moreover Keeping parameters such as radial and torsional stiffness at certain levels will increase both bushing life and It is also very important in terms of driving comfort. For example, increasing radial stiffness and torsion It is important to provide a rubber body that will keep its stiffness at low levels. it is a technical problem.

Despite the fact that various approaches and different horoscope structures have been put forward on this subject, there is no mention of it. A solution that fully meets the problem has not been found.

An outer shell in the balance bar bushing structure described in the patent document numbered EP1391333, It contains an intermediate shell and, in the middle interior, a rubber overlap surrounding the stabilizer bar. By doing this, the torsional resistance is lowered by the compression of the rubber. Here is the horoscope of the balance bar All the ability to jam inside the bush is from the amount of rubber that compresses the rod. is forthcoming. However, it makes it difficult to control the amount of compression on the balance bar and This results in a more homogeneous compression requirement. In the document in question, the sign of the sign any compression applicability and desired torsional stiffness There is no mention of a related approach.

In the patent document numbered EP0911195, there is a device for connecting a stabilizer to the motor vehicle body. rubber and metal bushing construction is mentioned. The solution described replaces the stabilizer in question. a surrounding rubber element and a metal sheath. The rubber element is inserted into the metal sheath in question. a fixed stop member and a closing member. balance bar here The amount of compression applied on it and its torsional stiffness cannot be kept under control.

In the patent document numbered U85520465, a plastic bushing is used for stabilizers in motor vehicles. construction is mentioned. The solution described here is one piece on the axial edge with a mesh It consists of two half shells that are connected to each other. where there are two half-shell network connections It has one of the two guiding elements on the edge and has a predetermined closed during assembly. is guided into position. As a result, the two half shells are cured in a mold in the 180° open position. can be achieved.

As a result, it is observed that the stabilizer bar is both tightened from the inside out and during the assembly. thanks to the developed technical features, it is ensured that it is compressed from the outside to the inside, and thus structuring a bushing in which the balance bar can be packed more homogeneously into the bush The need for the present invention has necessitated the emergence of the solution.

Said bushing (10) is attached to the vehicle body of the anti-roll bar, which prevents the vehicle from swinging in corners. it ensures its attachment.

The perspective view of the sign (10) which is the subject of the invention is given in figure 1. Basically the subject of the invention is the horoscope (10); In the corner regions (20), at least one corner support piece (21) and at least one intermediate shell (25) and all comprising at least one rubber body (30) that surrounds and connects them to each other. the aforementioned corner the support parts (21) are plastic and the intermediate shells (25) are aluminum sheet. However, these elements are They are substructures and can be obtained from different materials that can perform this function.

The corner support piece (21) has a rigid structure with respect to the rubber body (30). Also intermediate shell (25) Since its material consists of a metal such as aluminum or steel, it is more rigid than other elements.

The cylindrical shape formed in the middle of the rubber body (30), which preferably consists of two parts, for easy assembly. said anti-roll bar is placed in the gap (40). Said sign (10) has at least 2 signs part (11). These bushing parts (11) may be completely separate from each other. such as (figure 1), one end can be articulated with a rubber filling and the other end can be open (figure). ). Said bushing parts (11) surround the anti-roll bar from above and below, and are attached to the vehicle chassis. These parts can be named as the lower part and the upper part. Thus the aforementioned subpart The balance bar between the upper part and the upper part is attached to the vehicle body with a clamp from the outer part of the bushing (10). connection is completed. The mentioned bushing parts (11) are the horizontal axis (T) seen in figure 3. They are positioned in a symmetrical configuration relative to the line, The main function of the bush (10) is to dampen the vibrations coming from the road and go to the vehicle cabin. is prevention. The anti-roll bar, which can also be described as a torsion bar, In all cases, the vehicle wheels must be placed on the ground in order to compensate for the rolls caused by swaying in bends. makes it print. For this purpose, the balance bar rotates in the bushing (10). doing. If the bush (10) with the rubber body (30) meets these twists, the vehicle It determines the comfort in cornering transitions. For example, the torsion of the balance bar of the bush (10) If it shows excessive resistance to its movement, the vehicle will have a rigid suspension and It causes a knock that can be felt by the driver when passing. rubber softer responses in vehicle curvature transitions where it allows too much torsion In spite of the fact that the curves give way, there may be more side bending in the bends.

A perspective view of the external and internal structures of one half of the inventive sign (10) It is given in figure 2. The intermediate shell (25) mentioned in the present invention is an intermediate cylindrical plate (or sheet). two separate corner support pieces (21) positioned on the corner areas (20) of the bushing piece (11) the overlap between the rubber inner surface in the middle interior and the anti-roll bar. rate is reduced. Regarding this situation, after mounting the balance bar in the bushing, which is the subject of the invention, A cross-sectional view depicting the rate of overlap in the rubber in the section is shown in figure 6 are given. Here, the outer diameter of the balance bushing (60) is greater than the inner diameter of the rubber inner layer (70). is seen. Although the difference between these two diameters determines the overlap ratio (x), defines the amount of compression of the rubber. Said overlap ratio (x) is prior art It is held less than the solutions and the vibrations originating from the balance bar are absorbed. It fulfills its function more healthily with other technical abilities brought with the sign of the invention (10). is brought.

The front view of the bush (10), whose perspective view is presented in figure 1, is given in figure 3, while in figure 4 A cross-sectional view of the bushing part (11), which constitutes a half of the bushing (10), which is the subject of the invention, is given. In the previous technique, all the skill related to the compression of the balance bar in the bush (10) is inside the sign. It was due to the amount of rubber compressing the rod in the part. However, in the present invention preferably two outer intermediate shells (25) consisting of sheet metal and outside of these, which are positioned in the corner regions (20) By using the corner braces (21) there is a space between the braces (22) between them. is created. Thus, while the bushing (10) is mounted to the vehicle with the stabilizer bar, the clamp or said support parts by externally applied compressive force by means of a similar connection By decreasing the space (22) between these two parts, it is ensured that these two parts get closer to each other, and the intermediate shell (25) Compressing the outer rubber layer between the corner support piece (21) or the rubber body (30) is being implemented. Thus, the applied compression can be taken not only from the inside but also from the outside. A more homogeneous compression can be provided to the bar. Similarly, two-part The same technical features are located in the other half of the bush (10) surrounding the mentioned balance bar. takes. Also, when these two bushing parts (11) surround the stabilizer bar for assembly. balance between bushing parts (50) formed between said bushing parts (11) The subject of the invention is the amount of compression in the bushing (10) of the rod under control and at the desired level. allows it to be retained.

Thus, during assembly, the stabilizer bar is tightened both from the inside to the outside, while the mentioned support from outside to inside through gaps between parts (22) and distance between bushing parts (50) is compressed. Thus, the balance bar is packed more homogeneously into the bush (10). is happening.

Corner support with rubber outer layer (32) in the bushing (10) which is the subject of the invention in one embodiment. parts (21) and/or intermediate shell (25) are connected. Corner support of this rubber outer layer (32) on preventing incorrect positioning with respect to the parts (21) and/or the intermediate shell (25). provides a significant advantage. In other words, the outer rubber layer (32) of the anti-roll bar does not change its original (original) axial position in the direction of the axis. That is, the intermediate shell (25) position preserves. Thus, between the outer surface and/or the intermediate shell (25) and the rubber outer layer (32). It is ensured that the specified contact surfaces are in an unchanging configuration.

These technical features provide significant additional contributions and advantages. For example; to do this since a bushing (10) with a the whole load is not just internal, thanks to the relatively larger inner surface of the layer A more homogeneous load distribution on the bushing (10) and the balance bar as it is applied from the outside. provided, thus prolonging the service life.

The inventive bushing (10) is in the form of two bushing parts (11) as a requirement of its mounting. is revealed. However, it is a one-piece piece that will be articulated from one side and surround the balance bar. It can also be produced as a structure. As a result, the important thing in the sign of the invention (10) is the exclusions. rigid subcomponents or rigid substructures (intermediate shells (25) and corner bracings (21 )) consists of parts and they put a pressure on the bush (10) from the outside and therefore on the balance bar. is to have a structure that can be applied. Intermediate and outer parts (features) used in bushing (10) can be aluminum, steel or plastic.

The rubber material also fills between the intermediate shell (25) and the corner support parts (21), forming a rubber it provides the formation of the rubber body (30) by forming the inner layer (31) and the rubber outer layer (32).

The bushing (10) containing such a rubber body (30) helps to increase the radial stiffness and torsion. It helps to keep the resilience at low levels. The rubber body of the bush (10) Rigid substructures consisting of two parts on the outer part (30) are used for mounting the bush (10) to the vehicle body. used as support geometry. The space between the support parts formed by these two rigid parts (22) allows a compression to be applied on the outer layer of the rubber body (30).

The distance between the body or bushing parts in the vertical, that is, the lower and upper parts of the bush (10) (50) allows compression to occur on the outer rubber layer during assembly.

Thanks to the inner diameter of the rubber bush (10) reduced by ~20% compared to the diameter of the anti-roll bar, the bush (10) helps to prevent compression in the rubber inner layer (31) and rubber outer layer (32) is being made. Again, as mentioned above, compressions occurring in the inner and outer layers It is also possible to keep the torsional stiffness low and the life of the parts long. is provided.
