Description

[0001] EAR CIRCLIP

[0002] FIELD OF THE INVENTION

[0003] The invention relates to an ear circlip, which has been developed to eliminate the disadvantages arising from the mechanical deformations caused by the mechanical deformations to which the hollow circlips currently used to prevent the axial movement of the bearing cap in the universal joint in the cardan shafts are subjected due to their configuration.

[0004] PRIOR ART

[0005] The cardan shaft is a power transmission member that transmits the rotational movement and the power it receives from the engine to other transmission elements. It also serves to compensate for axial and angular movements under the vehicle caused by loads coming from the road. Angular compensation is achieved by the universal joint. Universal joint is an assembly structure containing a flange yoke, bearing cap and cross body, as seen in Figure 3.B. The universal joints mentioned above use hollow circlips that prevent axial movement of the bearing cap during operation.

[0006] It is essential that the circlip to be connected to the bearing cap have a structure that allows it to be grasped, especially during disassembly. For this reason, circlips that do not have any protrusions or holes are not connected to the bearing cap. Because after connection, when the circlip is grasped and pulled with the help of a pair of pliers, the pliers slide off the circlip surface and this situation increases the labour force and creates occupational health and safety risks.

[0007] There should be no protrusion at the ends of the circlips used in universal joints. Because, as seen in Figure 3.C, there is a limited space for the circlip connected to the bearing cap to flex during assembly and disassembly. If there is a protrusion at the ends of said circlip, the protrusion at the ends hits the flange yoke as the ring flexes. In addition, in angular movements of the cardan shaft, the protrusions at the ends of the ring hit the flange yoke. In order to eliminate these problems, circlips that do not have any protrusions are connected to the bearing caps. In order to remove said circlip from the bearing cap, holding devices are used to hold and pull the ring. In order to ensure that the holding apparatus does not slip from the circlip while tensile it, the circlips currently used have holes as seen in Figures 3 and 3.A. The circlip is pulled from the mentioned hole with the help of a pair of pliers and separated from the bearing cap. When it is to be mounted on the bearing cap, the ends of said circlip are stretched and mounted on the bearing cap.

[0008] The disadvantage encountered in the currently used hollow circlips shown in Figures 3 and 3.A is the mechanical deformation on the circlip caused by cracks and breaks that occur during assembly and disassembly. In order to mount said circlip to the bearing cap, the circlip is stretched from its ends and passed to the outer part of the bearing cap. During the mentioned assembly process, the upper part of the circlip hole is exposed to high compression force and the lower part is exposed to bearing cap tensile force. Fractures or cracks occur in the circlip hole due to the high tensile force it is exposed to. In this case, the circlip becomes unusable and causes financial losses. In addition, if said circlip cracks during the assembly process and this situation is not noticed, work accidents or high damage to the cardan shafts occur. The currently used hollow circlips are exposed to high tensile forces during assembly and disassembly due to their structure. Considering the negativities caused by high tensile force, it is extremely essential to find a solution to this situation. In addition, it is known that the mechanical resistance of the parts against compressive force is higher than the mechanical resistance against tensile force. In this case, it is extremely important to develop a ring that will be exposed only to compression force during assembly and disassembly of the bearing cap.

[0009] A high-strength circlip is mentioned in the application number CN21973386411. The circlip of the abovementioned application has protrusions at the ends and has a screwed structure, making it unsuitable for use in cardan shafts.

[0010] In the application numbered CN219639220U, a circlip to be used in high-speed shafts is mentioned. There are protrusions configured close to the ends of the said circlip. However, these protrusions are not in a geometry or position that will allow the circlip to be held and pulled with a pair of pliers.

[0011] An anti-loose circlip is mentioned in the application numbered CN21760310811. The mentioned loosening prevention process is provided by screws. However, considering that it is a screwed structure, it is necessary to have screw slots on the bearing cap to connect the circlip to the bearing cap. In this case, the circlip structure mentioned in this application is not suitable for use in cardan shafts.

[0012] Considering the above-mentioned unfavourable conditions, an ear circlip, which has been developed to eliminate the disadvantages arising from the mechanical deformations caused by the mechanical deformations to which the hollow circlips currently used to prevent the axial movement of the bearing cap in the universal joint in the cardan shafts are subjected due to their configuration, is required.

[0013] As a result, all abovementioned problems have made it necessary to make an improvement in the relevant technical field.

[0014] OBJECT OF THE INVENTION

[0015] The present invention aims to eliminate the abovementioned problems and to make a development in the relevant technical field.

[0016] The object of the invention is to ensure that the circlip is not subjected to tensile force during assembly and disassembly. In this way, cracks and fractures caused by tensile force are eliminated.

[0050] DETAILED DESCRIPTION OF THE INVENTION

[0051] In this detailed description, the inventive ear circlip (A) is described by means of examples only for clarifying the subject matter such that no limiting effect is created.

[0052] The invention relates to an ear circlip (A), which has been developed to eliminate the disadvantages arising from the mechanical deformations caused by the mechanical deformations to which the hollow circlips (S) currently used to prevent the axial movement of the bearing cap (M1 ) in the universal joint (M) in the cardan shafts are subjected due to their configuration.

[0053] The general structure of the ear circlip (A), whose appearance is given in the figures comprises the following;

[0054] • Body (1 ) connected to the bearing cap in order to prevent the axial movement of said bearing cap,

[0055] • Ear (2), which enables assembly and disassembly of the bearing cap without being exposed to mechanical deformation caused by the tensile force (TF) of said body (1 ).

[0056] Universal joint (M) is used to compensate for axial and angular movements in cardan shafts, as seen in Figure 3.B. Said universal joint (M) comprises; flange yoke (M3), cross body (M2) and bearing cap (M1 ). In order to prevent the axial movement of the bearing cap (M1 ), there is a circlip (S) connected to the bearing cap (M1 ), as seen in Figures 3.B and 3.C. The invention developed to eliminate the mechanical deformation caused by the tensile force (TF) under the hole in the hollow circlip (S) of the prior art shown in Figures 3 and 3. A on the hollow circlip (S), is an ear circlip (A), it refers to the realisation of the assembly and disassembly process with the bearing cap (M1 ) without any mechanical deformation thanks to the elements it contains and the structuring of these elements.

[0057] The invention comprises an ear circlip (A) and a body (1 ) for lining up with the bearing cap (M1 ), as shown in figure 1 , in order to prevent axial movement of the bearing cap (M1 ). Said body (1 ) has a semi-circular geometry in order to minimise flexing and to ensure contact with the bearing cap (M1 ). As shown in Figures 1 and 2, the body (1 ) comprises terminal ends (12), which are configured to be inclined towards each other and separated from each other. The aforementioned terminal ends (12) ensure that the body (1 ) is held on the surface of the bearing cap (M1 ).

[0058] The invention which is an ear circlip (A), as shown in figures 1 , 2 and 2. A, comprises the ear (2), which enables assembly and disassembly of the bearing cap (M1 ) without being exposed to mechanical deformation caused by the tensile force (TF) of said body (1 ), A cavity (3) is provided on both sides of said ear (2) for securely holding and tensile said ear (2) by an apparatus. Said cavities (3) have a rounded surface. In this way, the apparatus that holds and pulls the ear (2) is prevented from causing wear and tear in the cavities (3). As seen in Figure 2. A, it contains a radius surface (11 ) that creates a recess towards the center of the said body (1 ) to ensure that the said ear (2) has a minimum diameter. In this way, the movement of the universal joint (M) on the cardan shaft is ensured without hitting the ear circlip (A).

[0059] The invention is the ear circlip (A) and has a monobloc structure. In this way, it provides maximum strength with minimum equipment and production costs.

[0060] All circlips are held and pushed or pulled by a device from the holding section (TB) to ensure assembly and disassembly. The circlips flex during the assembly and disassembly. This process mentioned is also valid for hollow circlips (S).

[0061] Due to the stretching mentioned above, tensile force (TF) occurs in the part close to the inner diameter of the holding section (TB) of the hollow circlip (S), and compression force (CF) occurs in the part close to its outer diameter. As seen in Figures 3 and 3. A, the tensile force (TF) occurring under the hole in the currently used hollow circlips (S) creates mechanical deformation in the existing thin wall originating from the hole. The invention is an ear circlip (A), and thanks to the ear (2) in the holding section (TB) and the cavity (3) on both sides of the ear (2), it is ensured that the part of the holding section (TB) exposed to the tensile force (TF) due to the flexing of the terminal ends (12) during the connection of the body (1 ) and the ear circlip is strengthened in such a way that it does not undergo mechanical deformation.

[0062] Thanks to the configuration of the ear circlip (A), mechanical deformations caused by the tensile force (TF) encountered during assembly and disassembly of the currently used hollow circlips (S) is eliminated.

[0063] The protection scope of the invention is specified in the appended claims and cannot be limited to the description made for illustrative purposes in this detailed description. Likewise, it is clear that a person skilled in the art can present similar embodiments in the light of the above descriptions without departing from the main theme of the invention.
