Abstract

The invention relates to the design of the eye part (the articulated part where the leaf spring is attached to the vehicle) of the leaf springs made of composite material used in automotive or railway transportation (Heavy, Light commercial vehicles or automobiles, etc.) and the production technique of this eye part.

Description

TECHNICAL FIELD The invention is used in automotive or railway transportation (Heavy, Light commercial vehicles). or in automobiles etc.) leaf springs made of composite material the design of the part (the articulated part to which the leaf spring is attached to the vehicle) and the production of this eye part (A similar articulation connection is found in the automobile front wheel system. Also available in swings. Here is a system similar to the articulation system which is the subject of the invention. manufacturing and design can be done.) KNOWN STATUS OF ART Leaf springs are used in all kinds of vehicles. (Phaes, trains, automobiles are light or heavy commercial vehicles etc.) Since it is frequently used in the automotive sector, the expression automotive will be made through the industry.

Leaf springs used in automotive are made of alloy steel materials, hot or cold. It is produced by production techniques (rolling, drilling, etc.). Leaf springs of different types There are also different types of leaf spring eye designs. leaf spring types are collected in two main groups as parabolic and conventional. (Parabolic type while the section thicknesses of the springs vary towards the leaf spring length. section thicknesses are constant in conventional leaf springs. More than one type They can consist of parts (layers).) There are different eye types in Figure-1. in Figure-1 normal eye (1 .a), inverted eye (1 .b) and Berlin eye (1.0). (“Berlin” in “Berlin eye” is a general name given specifically to that structure).

The assembled position of the leaf spring on the vehicle and its movement during operation style can be explained as follows; A leaf spring is attached to the fixed earring (2.6) on the vehicle chassis (2.8) as in Figure-2. The leaf spring rear eye (2.5.2) is attached to the movable earring (2.4) with the front eye (2.5.1). Vehicle by tightening the “U” connection hardware (2.2) to the axle (2.1) and replacing the leaf (2.5) on the vehicle. is stuck.

Eye types are also shown in Figure-3 with the leaf spring (2.5) on the vehicle removed. is seen. Here, the bushing (3.1.a) and rear eye (2.5.2) inserted into the front eye (2.5.1) The rear bushing (3.1.b) attached to it is seen. Front bush (3.1 .a) and rear bush (3.1 .b) leaf After being attached to its places on the spring (2.5), the leaf spring (2.5) becomes as seen in figure-1. the eye joint bolt (3.3) of the fixed earring, the knuckle on the fixed earring The front eye (2.5.1) is attached to the front fixed earring (2.6) by passing it through the hole (2.6.1). Similarly rear fixed earring (2.7) to rear fixed earring knuckle bolt (3.4) rear fixed earring joint the movable earring through the upper knuckle hole (2.4.2) at the same time. the movable earring (2.4) can be attached to its place on the rear fixed earring (2.7). Front after attaching the posterior eye bush (3.1 .b) to the posterior eye (2.5.2) similar to the one in the eye (2.5.1) The rear eye (2.5.2) is brought to the eye part of the moving ear piece (2.4.1) and the movable ear can be fixed on the eye joint. The bolt (3.2) is passed through the eyepiece hole (2.4.1.a) of the movable earring and the rear eye (2.5.2) and the movable earring (2.4) are attached to each other.

Vehicle movement direction (3.5) is shown in Figure-4. Therefore, in this direction The anterior eye (2.5.1) is called the posterior eye (2.5.2), and the eye in the other direction.

When the wheel (2.3) encounters any pothole on the road while the vehicle is on the road, in the downward movement of the wheel (4.1) the movable ear (2.4) the rear fixed ear knuckle By turning the bolt (3.4) clockwise, the leaf spring (2.5) shrinks and becomes the one in Figure-4. they get it. At the same time, the front eye (2.5.1) is fixed around the eye joint bolt (3.3). while rotating clockwise, the rear eye (2.5.2) is relative to the moving ear (2.4) the eye joint bolt (3.2) rotates counterclockwise around it.

In Figure-5, when the wheel (2.3) encounters any bump in the road, movable earring (2.4) in upward (5.2) movement, rear fixed earring knuckle bolt (3.4) Leaf spring (2.5) is shaped by stretching (extending) by rotating counterclockwise around it. It allows it to take its form in . At the same time, the front eye (2.5.1) is fixed earring eye joint bolt. (3.3) rotates counterclockwise around it, but the rear eye (2.5.2) is relative to the movable earring. (2.4) the movable earring rotates clockwise around the eye joint bolt (3.2). Figure-4 and the operation of the Fig-Site leaf spring system is explained.

Since the leaf spring carries all the weight on the axle of the vehicle under the vehicle. It is quite heavy as it has been produced from alloy steel material so far to be durable.

(They can be up to the weight of an adult).

Since it moves by constantly stretching, the material gets tired after a while and it is in its content. It causes small cracks to form and then break. (A certain lifetime has) reason; front and rear during movement of the wheel (2.3) down (4.1) and up (5.1) eyes (2.5.1) (2.5.2) clockwise and counterclockwise weight of the vehicle on the axle (2.1) If the bushes (3.1.a) (3.1.b) are not in the eye, they are under this load because they move under it. there is a possibility that the eyes of the scissors (2.5.1) (2.5.2) may be damaged due to friction.

Also, bushing materials contain rubber in some cases. (two pipes inside each other There is rubber material between (comfortably available in the market)). your wheel the impact of the impact loads that occur in sudden movements on the eye joints. intended to prevent.) Vehicle manufacturers are increasingly fueled by the automotive industry. to produce vehicle parts from lighter and more durable materials. is working. Leaf spring is one of these materials. Therefore, composite is directed to the materials and there are studies related to this. (Composite: At least to bring together the best features of two different groups of materials, or to combine two materials formed by combining these materials in order to bring out a new feature that is not in called materials. In other words, by correcting each other's weak points or by made of different kinds of materials or phases combined to increase their properties. are materials.) As an example of composite materials used in the automotive industry; carbonfiber- epoxy, fiberglass-polyester, fiberglass-epoxy, kevlar-epoxy, etc. material pairs are used primarily in automotive, boat building and so on. in sectors (Carbon fiber, glass fiber, kevlar materials are also hair-thin They are materials consisting of fibers that can show high resistance to longitudinal tensile forces.

As a result, the part made of composite material will be damaged.

The numbers of some of the patent applications related to the composite leaf spring; The subjects of these patent numbers are partly related to the subject matter of the invention. are available. However, this interest is due to the eye design of the already used steel leaf springs. For an eye design similar to the eye design with a steel spring in patent No. to the composite leaf spring tip; can be composite as well as another A kind of piece of composite leaf spring end part, which can also be manufactured from material, is perforated. mounted with the help of screws.

Puncture made in such a way as to disrupt the fiber integrity in the composite material and cuts (when the composite leaf spring is operating under the vehicle) can cause structural damage. and leaf springs may shorten their lifespan. (Especially opening at the end of the composite material during screwing to be attached to the material. holes) Although the integrity was tried to be established by putting the material on the parts again, the fiber still remained. its integrity is broken because it is cut and therefore the material strength is lost is happening.

OBJECTIVE OF THE INVENTION The object of the invention is to use any shape in the eyepiece design of the Composite leaf spring. without disturbing the fiber integrity in the leaf spring (cutting, drilling, etc.) and leaf spring a composite leaf spring eye that will not limit its movements in the working environment is to perform.

Another purpose of the invention; Composite leaf spring eye design which is the subject of the invention It is the realization of more production in a certain period of time during the production.

human skeletal system in Figure-6 is seen. Figure-6 shows human pelvic bone (Legen bone) (6.1), Femur bone (6.2), spherical femoral head(6.3) spherical femoral head (6.3) in pelvic bone(6.1) acetabulum (6.5) in the form of a hollow hemisphere to which it is attached (acetabulum; given to 0 place (type also) is a special name) intra-acetabulum cartilage (6.5.1) over the spherical femoral head cartilage(6.3.1) is seen. downward force pelvic bone due to human weight The forces acting on the entire surface of the hollow hemispherical acetabulum over (6.1) (6.6) transmits to the spherical femoral head (6.3) attached to the acetabulum (6.5). giggles here In order to prevent the wear that will occur due to the friction that occurs as a result of are available. Since the connection here is spherical, the femur (6.2) bone can be rotated in all directions (spherical rotation) can make rotational motion. (Fig.-6 global skeletal system is a cross-sectional view of the joint.) In the state of the art, in Figure -4 and Figure-5, the leaf spring front chamber (2.5.1) and The rear eye (2.5.2) is in one axis in the movement of the wheel (2.3) up (4.1 ) and down (5.1) They move clockwise or counterclockwise.

Uniaxial clockwise or counterclockwise of leaf spring eyes (2.5.1) (2.5.2) As in its return, the composite leaf spring eye design, which is the subject of the invention, is also Without disturbing the continuity of the fiber fibers contained in the composite leaf spring (drilling, cutting etc.) must allow this movement.

Sehit-6 also has a spherical joint, acetabulum (6.5)-spherical femoral head (6.3) pair. The cylindrical joint system (7) in Figure-7 is similar to the composite scissor eye design. has been applied.

In Figure-7, opposite to the acetabulum (6.5) in Figure-6, the cylindrical "C" bearing (7.1) and there is a cylindrical joint (7.2) as opposed to a spherical cylindrical femur (6.3). joint cylindrical clockwise or counterclockwise around the cylindrical axis (7.5) only. can return. Figure I-6 shows the spherical femoral head (6.3) in the human skeletal system in the pelvic bone. (6.1) is seated from the femur (6.2) to the pelvic bone so that it does not protrude from the acetabulum (6.5). (6.1) is connected with muscles. (Fig.-6 deals with the skeletal system and Since it is generally known how the spherical connections are, the positions of the muscles are shown in the figure. not shown above.) In Figure -7, in the cylindrical "C" bed (7.1), it is attached to the pelvic bone of the femur (6.2) with muscles. place of attachment; the upper alpha angle (7.3.1) and lower beta angle (7.3.2) of the cylindrical “C” bearing The upper end (7.3.1.a) and the lower end (7.3.2.a) of the corresponding “C” bearing meet the parts.

This happens in the form of water; Cylindrical joint (7.2) clock around cylindrical axis (7.5) If the cylindrical "C" bearing is pulled in the opposite direction (7.8) while turning in the direction or opposite direction, "C" cylindrical in each angle segment in the entire upper alpha angle (7.3.1) at the upper end of the bearing (7.3.1.a) occurs. Similarly, at the lower end of the “C” bearing (7.3.2.a) the entire lower beta angle (7.3.2) “C” bearing lower angle on the entire surface across the width of the cylindrical “C” bearing in each angle segment reaction forces (7.7.3) occur. (The upper and lower angle response in only one angle slice forces(7.7.2)(7.7.3) are shown.) Moreover; Figure-6 is similar to the forces acting on the entire surface of the acetabulum (6.6). It occurs in forces similar to the forces, these are; Cylindrical “C” bearing Cylindrical “C” at each angle segment at 180° head angle (7.3.3) Head angle reaction forces (7.7.1) over the entire surface along the bed width (7.1.G) (only one The head angle reaction force (7.7.1) in the angle slice is shown.) cylindrical joint (7.2) cylindrical "C" when rotating clockwise or counterclockwise around the cylindrical axis (7.5) If it is pushed in the direction of the bearing (7.9), reaction forces will occur in the opposite direction. preventing it from coming out of the cylindrical “C” bearing; from the sections of the cylindrical “C” bearing It can be in the form of a cylindrical “C” bed, or it can be mounted to each other.

In Figure-7, cylindrical “C” bearing (7.1)-cylindrical joint (7.2) pair; Cylindrical “C” bearing cylindrical axis when pushed and pulled in direction (7.9) or vice versa (7.8) and/or simultaneously (7.5) allows clockwise or counterclockwise rotation around and away from each other. they are inseparable. Cylindrical joint (7.2) cylindrical axis direction (7.5) cylindrical “C” bearing fully If they are pulled in the opposite direction, they will separate from each other. To prevent this situation, move in this direction. restrictors to prevent this can be used with this cylindrical joint system (7). (Figure-18 In this case, it is explained as the left valve (18.1) and the right valve (18.2). However, in this direction movement can be prevented by any other method.) When the leaf spring is made of composite materials, the leaf spring has front and rear eyes. The earring (2.7) will also be likened to the cylindrical “C” bed in figure-7. This composite leaf spring (10) (in figure-10) is manufactured for eye (8) (alternative winding is also seen in figure 9.) similar to cylindrical joint (7.2) has been created.

In Figure-8, the north-south winding eye (8) (fiber fabric is hand-made and/or machined). can be created by wrapping, as described with the help of Formation of coiling of fibers as in mushroom-like shape with flow first stage (8.B), second stage (8.C), third stage (8D), and fourth stage, respectively. stage (8.E). (The number of stages described here can vary completely. The important thing is that the north- is to form the south winding eye.) In the northern region (8.K), the northern region is fiber fabric (8.2), In the southern region (8.G), there is fiber fabric (8.1) in the southern region. North The fiber fabric in the region passes to the southern region and becomes the southern region fiber fabric. at the extreme (8.3) (This point may also be broken. North fiber fabric vs south fiber fabric It can also be completely separate) in the first stage (8.B). The tip in the first stage (8.B) point (8.3) disappears in the second stage (8.C), the northern region fiber fabric end point (8.5) and The southern region fiber fabric endpoint is created. Transition from the second stage to the third stage fiber fabric endpoint (8.7) of the northern region in the state of the north similarly, although the region is further north from the fiber fabric endpoint (8.5), Southern zone fiber fabric endpoint in transition from the second to the third stage The southern region formed in the first step in (8.6) is lower than the fiber fabric end point (8.4). is located in the south. In the third stage (8.D) the north point at the end of the second stage (8.7) is clockwise the third stage north region fiber fabric endpoint (8.9) similar to In the figure, the south point (8.8) at the end of the second stage is on itself counterclockwise. folded to form the third stage south region fiber fabric endpoint (8.8). This the required amount after the step (how much is the size of the north-south coiled eye (8)? If desired, a north-south winding eye (8) can be created by winding. finished north-south winding towards the center of the eye (8.M) with the northern region fiber fabric (8.2) The fabric of the southern region (8.1) merges and in the northern part (8.K) half of the eye and the south It gets stuck between the part in the region (8.G). To the fiber fabric found here when resin is added (a binder used in the manufacture of composite materials) resin) which means that the eye (8) and the composite cylindrical joint leaf spring (10) are physically strengthens its integrity. As seen, the fiber fabric surrounding the eye is divided into two when it comes to the eye area. is separating. In this case, although the fiber fabrics are glued together with resin, In addition, upper and lower fiber fabric adhesion will be able to separate from each other adhesion region) Alternative winding technique is shown in Figure-9. Here, the winding in figure-8 There are stages similar to the technique; alternating winding first stage(9.B), alternative The winding is the second stage (9.C), the alternative winding is the third stage (9.D). In the northern region (8.N); alternatively wound fiber fabric in the north (9.2), and in the south (8.G); alternative there is a winding south region fiber fabric (9.1). Fiber fabric in the northern region At the extreme point (8.3) where it passes to the north region and the south region becomes fiber fabric. There may also be a disconnection. The northern fiber fabric and the southern fiber fabric can also be completely separated) in the first stage (9.B). End point (9.3) in the first stage (9.B) alternate winding In the second stage (90), the northern region becomes the fiber fabric end point (8.5) and turns clockwise. required amount (the size of the eye (9) with fiber fabric wound on itself is desired) By winding, the fiber fabric wound eye (9)0 can be formed on itself.

Fiber fabric in the manufacture of composite cylindrical hinged leaf spring (10) in Figure-10 fiber fabric (10.F) coming out of the spool (10.M) composite leaf spring from the fiber spool from the composite leaf spring entry point of the fiber in the direction of the fiber's direction (103.1). (10.G) enters to form cylindrical jointed leaf spring. Afterwards, the fiber fabric The fiber is wound in the direction of the fiber reel direction (10.32) creates the eye (10.1). Then the fiber moves in the direction (10.3.3) to the other eye. Towards the fiber entry point (10.3.4) after forming the other fiber wound eye (10.1) it moves out, where the fiber fabric (10.F) is cylindrical without any interruption. joint completes the composite leaf spring formation. (The reason for the continuous formation; the end point in the first stage (8.B) in both the north-south region fiber fabric wound eye (8) The end point in the first stage (9.B) in both (8.3) and the eye (9) with a fiber cloth wound on itself The fiber fabric (10.F) coming out of the fiber fabric reel (10.M) Both fiber coil eyes (10.1) on the composite cylindrical joint leaf spring (10) can also be created.) Occurs during the movement of the femur bone (6.2) in the human skeletal system. acetabular cartilage (6.6) and spherical femoral head cartilage to reduce friction (6.4) exists. Similarly; fiber formed in the eye area in composite scissors the friction caused when working in the cylindrical “C” bearing (7.1) of the coiled eyes (10.1). “C” eye in the manufacture of composite cylindrical joint leaf springs to prevent-reduce before it is closed (before the resin cures (freezes) in the mold).

Composite cylindrical hinged leaf spring (10) production is finished and it is removed from the mold (10.2) (10.3). “C” eye protectors (10.4) adhered to the fiber wound eyes (10.1) when removed somehow (so that the composite leaf spring cannot be removed without damaging it) as a whole. exists as.

Composite cylindrical joint leaf spring width (10.V) fiber fabric during manufacturing It is related to the width (10.FG). Multiple composite cylindrical hinged sheets at a time When the spring (10) is to be manufactured, the fiber fabric width (10.FG) is equal to the total width. The composite leaf spring (10) is wound in a width equal to the total width at one time, and fiber-wound eyes so that the width of the eye shield (10.C) is similar to the overall width After placing it on (10.1) and adjusting the mold width (10.K) appropriately, manufacturing makes. In short, fiber fabric width (10.FG), mold width (10.K), Eye protection width (10.C) is a mathematical relationship between the leaf spring width (10.V) with composite cylindrical joint. There is a dimensional relationship. Thanks to this relationship (such as bread slices), the desired number of composites The cylindrical hinged leaf spring (10) can be formed by cutting it to length. as a preservative (10.4) in figure-11; With friction damage reduction “C” eye protection (11.1) friction damage reducing “C” eye protection with shock absorbing material (11.2) is seen. Both protectors (11.1) (11.2) have a rough inner surface (11.1.P).

In Figure-12, the production is finished; North-south region fiber fabric wound eye (8) A “C” eye protection (11.1) is placed on it to reduce the friction damage and is made of resin (12.1). together it becomes similar to the cylindrical joint (7.2) as a whole.

A similar situation is seen in figure-12, with the fiber fabric in the north-south region being finished. "C" eye protection with shock absorbing material on the wrap-around eye (8) to reduce friction damage (1 1.2) inserted and together with resin (12.1) resembles a cylindrical joint (7.2) as a whole has become.

The rough inner surface (11.1.P) of the resin in both types of eye protectors (11.1) (11.2) Friction damage eye protectors (11.1) as they are fully filled by (12.1) (11.2) ensures that it is fixed in its place in figure-11 and figure-12 and does not come off.

Only wear damage-reducing “C” eye protection (11.2) interior with Sok-absorbent material. There is a shock absorbing material between the two "C" parts(11.3)(11.4)( Outer "C" protective part (11.3), inner“C” part (11.4) and shock absorbing intermediate material (11.D) are a whole.

Why is rubber material bushings needed in the state of the art? has been explained. Shock absorbing material is used for similar reasons.) It contains shock absorbing material (11.D) between The composite scissors (10) are inserted into the cylindrical “C” bearing fixed earring (15) in figure-15. First of all, the “C” bushing (14) with shock absorbing material is placed and the bolts (15.1), cylindrical “C” “C” bushing with shock absorbing material by passing through the holes (15.2) on the bearing earring. It is screwed into the bolt holes (14.3) on the Thus, the bushing (14) is inside the fixed earring (15). will be fixed After fixation, friction damage reduction “C” eye protection The composite leaf spring cylindrical joint (12) is inserted into the bush, as in figure-7, with the cylindrical axis. (7.5) is attached by moving it. (Cylindrical joint without bushing (14) can be used.) “C” eyelet with friction damage reducing and shock absorbing material in Figure-16 guarded composite leaf spring cylindrical joint (13) to cylindrical “C” bearing fixed earring When it is to be attached, it is also necessary to attach the “C” bush (14) with shock absorbing material as in figure-15. There is no need. Because the eye (13) already has the shock absorbing material on itself during manufacturing. by the shock-absorbing material friction damage-reducing “C” eye shield (11.2) fitted is provided.

It is similar to the movable earring (2.4) mentioned in the state of the art, but Instead of the movable ear piece (2.4.1), Figure-17 shows the cylindrical “C” bearing (17.1) for the movable earring. cylindrical “C” bearing movable earring (17) and composite cylindrical joint leaf spring (10) can be attached. (Composite leaf spring with cylindrical joint (10) fixed with cylindrical “C” bearing The “C” bushing (14) with shock absorbing material used when attaching to the earring (15) is similarly cylindrical. mounting techniques are similar for the cylindrical “C” bearing movable earring (17).) Single chamber or For leaf springs with one eye of the old type, fixed (15) and movable (17) earrings can be used at the same time or can be found separately.

As explained in Figure-19 and Figure-20 in the state of the art; (Figure I-4 and Figure- the leaf spring (2.5) in cylindrical “C” in the downward movement of the wheel (4.1) when it encounters a pit bearing movable earring (17) clockwise around the rear fixed earring knuckle bolt (3.4) By turning, the cylindrical hinged composite leaf spring (10) is contracted to form in Figure-19. they get it. At the same time, the fiber fabric inside the cylindrical “C” bearing fixed earring (12) wound composite front cylindrical joint eye (19.1) around cylindrical axis (7.5) hours the fiber inside the cylindrical “C” bearing (17.1) of the movable earring, although fabric-wrapped composite rear cylindrical hinged eye(19.2) movable earring on “C” bed(17.1) rotates counterclockwise around the cylindrical axis (7.5).

In Figure-20, while the vehicle is on the road, the wheel (2.3) is not affected by any bumps on the road. cylindrical “C” bearing movable in the upward movement of the wheel (5.1) the earring (17) rotates counterclockwise around the rear fixed earring knuckle bolt (3.4). cylindrical hinged composite leaf spring (10) elongates, allowing it to take its shape in Figure-20.

At the same time, fiber fabric wound composite in the cylindrical “C” bearing fixed earring (12) front cylindrical joint eye (19.1) counterclockwise around the cylindrical axis (7.5) fiber fabric inside the cylindrical “C” bearing (17.1) of the movable earring coiled composite rear cylindrical hinged eye (19.2) relative to bearing “C” (17.1) rotates clockwise around the cylindrical axis (7.5). Thus, the cylindrical articulated composite leaf spring (10) it completely meets the logic.
