1 TARIFF AN OIL LEAK PREVENTER USED IN DUAL-MASS FLYWHEEL ENGINEERS. Technical Area The invention relates to an oil leakage inhibitor used in dual-mass flywheels. State of the Art 5 Dual-mass flywheels used in motor vehicles utilize internal combustion engines to produce flammable liquids. by damping torsional vibrations and angular acceleration fluctuations, the transmission and Mechanical design developed to reduce dynamic loads transmitted to the drivetrain. These are the components. The flywheels mentioned are the first flywheel connected to the engine side and the transmission. It consists of a second flywheel connected to the side, and the 10 between these two masses Relative angular motion, spring elements located within the first flywheel housing. This is achieved by elastic damping. For springs to operate efficiently and without friction, To minimize wear and ensure acoustic performance, the inner part of the first flywheel... It is essential that the container contains grease. In existing dual-mass flywheel designs, the assembly sequence is generally as follows: 15 This is implemented as follows: primarily the springs, drive flange and other related components of the first flywheel. It is placed inside the body, then the first flywheel cover is welded on. The internal volume is closed by fixing it to the flywheel. Following this process, the second flywheel is attached to the first flywheel. The drive flange is attached via rivets through the mounting holes located on it. These holes, used for connection and finally during the assembly process, are the oil drain plug plate 20. The system is sealed by covering it with sheet metal elements called [name of element]. The way the oil plug plates are fixed to the flywheel housing in the current technology varies. It may be insufficient under operating conditions, especially when applied on an assembly line. during processing, vibrations the product is exposed to during shipment and transportation or centrifugal forces generated when the vehicle is operating at high engine speeds 25 and under the influence of dynamic vibrations, through the mounting holes of the aforementioned oil drain plug sheets It is known to detach or become dislodged. Detachment of the plug plate. As a result, the first flywheel mounting hole is exposed, and the flywheel interior can be accessed through this hole. The grease contained within the system is leaking out. The leaking grease is being transferred... Contact with other components of the organs can cause contamination and functional impairment in these components. This can lead to malfunctions. Additionally, grease loss can cause damage to the first flywheel. 2 Lack of adequate lubrication in the springs can cause problems between the springs and the spring-body connection. This causes increased friction on contact surfaces, and consequently, wear. This situation negatively affects the vibration damping performance, which is the primary function of the dual-mass flywheel. This affects the vehicle, leading to increased noise, vibration, and harshness (NVH) issues, and engine problems. This causes the vibrations to be transmitted to the cabin more noticeably. 5 Therefore, in current techniques, grease leakage cannot be permanently prevented in oil plug plate fixing methods. A solution is needed to prevent this. In conclusion, due to the negative aspects described above and the current solutions being the subject of discussion... Due to its shortcomings, an improvement is needed in the relevant technical field. It has been made. 10 Purpose of the Invention The invention was created by drawing inspiration from existing situations and overcoming the aforementioned drawbacks. It aims to solve the problem.

That is, the installation of the oil plug plates used to cover the first flywheel mounting holes, 15 double displacement resulting from working conditions on shipment or vehicle Leakage of grease from the bulky flywheel's internal volume outside the system and consequently Contamination in the drivetrain and insufficient lubrication of the flywheel springs cause them to malfunction. The goal is to provide a permanent and reliable solution to the problem of its inability to function properly. In the invention developed for this purpose, the assembly located on the first flywheel is 20 a grease plug in the hole, unlike the grease plug sheet used in current applications. The installation of the nut is foreseen. The aforementioned oil plug nut is located on the second flywheel. During assembly to the first flywheel, the diameter section is crushed using a press machine. It is fixed to the mounting hole by being mechanically locked in place. The crushing process, carried out in this manner, involves 25 cm of material inside the mounting hole of the oil plug nut. permanent without showing any play or displacement in the axial and radial directions. This ensures that it is positioned in this way, thus preventing the use of classic oil drain plug plates. The aim is to prevent the displacement problem that is observed. Another objective of the invention is that, after all assembly processes of the dual-mass flywheel are completed, The system completely prevents grease from leaking out at any stage. The aim is to provide an additional sealing measure that will prevent this. In this context, the second flywheel. 3 An oil plug is inserted into the inside of the oil plug nut, which is locked by a crushing method. The mounting hole is completely sealed by screwing in the bolt, ensuring a watertight system. It is reinforced with a second mechanical barrier. This two-stage locking and closing mechanism... Thanks to its structure, it is used both during the processes applied on the assembly line and during the product's manufacturing process. vibrations encountered during shipping and transportation processes, as well as the high altitude of the vehicle 5 centrifugal forces and dynamics generated during engine operation Even under vibrations, the grease is effectively prevented from escaping the system. Another aim of the invention is to prevent grease leakage within the first flywheel. the springs and other moving components are in a continuous and adequate lubrication environment by ensuring its operation, it reduces friction and resulting wear between these components. to reduce, and therefore torsional and engine vibrations, which is the primary function of the dual-mass flywheel. The goal is to maintain damping performance even during prolonged use. This allows the grease to... Preventing noise, vibration and harshness (NVH) problems caused by loss of power and vehicle Reducing engine vibrations transmitted to the cabin is also one of the technical achievements of the invention. It is among the results. 15 Another purpose of the invention is to prevent leaking grease from reaching transmission and other drivetrain components. by coming into contact with these components, it can lead to contamination and possible functional deterioration. to prevent opening and reduce maintenance and warranty costs throughout the vehicle's lifespan. is the reduction. Another objective of the invention is to place 20 threads into the first flywheel mounting hole and crush them using a crushing method. consisting of a locking oil drain plug nut and an oil drain plug bolt fitted onto that nut. Thanks to its double-stage sealing structure, the vehicle is protected from the installation of dual-mass flywheels. The problem of grease leakage persists throughout all processes, from its initial application to its final use. eliminating this and thus improving both product performance and usability. increasing its lifespan. 25 The structural and characteristic features and all the advantages of the invention are given in the figures below. This becomes clearer thanks to the detailed explanation written with references to these figures. This will be understood, and therefore the evaluation should also take these forms and detailed explanations into consideration. It needs to be done by taking precautions.

(5) and together with the helical springs (3) positioned in its interior volume, as a single mass is in motion, and the primary mass of the dual-mass flywheel on the engine side It is formed by the second flywheel (2) which is on the clutch plate by friction. It constitutes the area in which it operates and, independently of the first flywheel (1), the gearbox 30 It acts as a secondary mass on the side. First flywheel (1) and second flywheel (2) They operate mechanically separately from each other, and their relative angular relationship... The movement is elastic by means of springs (3) which are mounted in the inner volume of the first flywheel (1). It is being damped as follows. Springs (3) improve the noisy behavior of the vehicle and reduce fuel consumption. For this purpose, torsional vibrations produced by the engine and vehicle vibrations are reduced to 5 It has a damping function. The springs (3) can work efficiently, quietly and rigidly. Grease oil (6) is used in the region where it is located, and grease oil (6) springs (3) By reducing friction, it provides a vibration-free and low-noise working environment. The drive flange (4) transmits the engine torque from the first flywheel (1) to the second flywheel (2) via springs (3) It is the component that performs the transmission function. The spring (3) which is mounted inside the first flywheel (1), 10 grease (6) and drive flange (4), first flywheel fixed to the first flywheel (1) by welding. is isolated from the external environment by the cover (5) and the first flywheel cover (5), It traps the components and grease (6) in the inner volume of the first flywheel (1).

In order to make this connection, 15 There is a first flywheel mounting hole (7) on the first flywheel (1), and the second flywheel Access through this hole (7) during the riveting process of the drive flange (4) with (2). This is ensured. After the riveting process is completed, the first flywheel assembly is carried out. hole (7) remains open and if this area is not closed, the first flywheel (1) inside There is a possibility of leakage of grease (6) in the volume. 20 In the previous technique, an oil plug plate was used to close the first flywheel mounting hole (7). (11) is used and the oil plug plate (11) is in the first flywheel mounting hole (7) It is assembled by connecting directly. However, the mounting hole (7) of the oil plug plate (11) This type of connection on it is suitable for assembly, shipping or working on the vehicle during sufficient mechanical resistance to vibrations and high rotational forces encountered 25 It does not show, which causes the oil plug plate (11) to detach and the grease (6) This leads to leakage outside the system. In the invention, as a solution to this problem in the previous technique, an oil plug plate (11) is used instead of an oil plug plate. Oil plug nut (9) is used. Oil plug nut (9) is inserted into the first flywheel mounting hole (7) is placed and riveting of the drive flange (4) with the second flywheel (2) in this hole (7) 30 It is mounted in the area used during the process.
