    Description
    [0001] The present invention relates to a bearing arrangement for a spring, in particular for a spring of a vehicle chassis, which has at least one spring insert in which at least part of a spring coil spring it accommodates, and on the other hand the spring insert comprises an elastomer and is designed to be flexible, while the spring insert is executed to be movable with a movement of the spring coil.
    [0002] To receive a spring, in particular, inside vehicle chassis, mainly from the spring plates served, and a spring is supported with at least a part of an end-side spring coil on the spring plate. To prevent the designed metal spring from coming into direct contact with a metal spring plate or other metallic feature that provides necessary support, spring inserts are known so that the end-side spring coil can be received either at the end. first and second end of the spring. The spring insert can be supported on a spring plate with a spring insert disposed at the lower end of the spring.
    [0003] Elastomers are materials suitable for forming spring insert such that the end of the spring is seated in a material in a soft and resilient material.
    [0004] During operation, the spring engages in a relative movement of the spring plate and the spring insert that specifically results from a rolling motion of the spring coil that is seated in the spring insert.
    [0005] By the rolling movement resulting from the end of the spring between the spring plate and the rolling coil of the spring, an opening and closing gap can occur. Despite the elastic spring insertion and the resiliently designed spring, the strong influence of dirt and moisture can cause an overlapping edge and grinding effect on the spring coil surface, and can induce damage to the spring lacquer coating. Previous Technique
    [0006] A bearing arrangement for a vehicle frame spring is known from DE 10 2008 046 939 A1. It is recommended that the spring insert in the spring be vulcanized immediately. This prevents the formation of a gap between the spring coil and the spring insert, but a vulcanization of an elastomer into the spring is labor intensive and limits the possible type of material used for the spring insert. For this purpose, it is especially recommended to provide a spring insert to mount over a spring that is in a state of not being fully vulcanized. The spring insert material should only be fully vulcanized when the spring insert is in its final condition, when the spring insert is vulcanized to the spring. Furthermore, a primary coating is required to apply to the spring coil onto which the spring insert will be cured, further increasing the vulcanizing effort of the spring insert onto the spring coil.
    [0007] A bearing arrangement for a spring is known from DE 10 2007 003 782 A1, which can be used for a vehicle chassis with a spring insert, which is vulcanized to the spring wire in the spring coil profile. On the other hand, it is indicated that, due to the joint material joined between the coil spring and the spring insert, a metallic contact between the spring and the spring plate cannot occur, on the other hand, it is indicated that, due to the vulcanization of the spring insert, an opening and closing gap between the lower end of the coil and the recess of the spring insert is prevented from occurring because all movements of the coil spring and the coil are followed by the vulcanized bearing. Unfortunately, the process of vulcanizing the spring insertion into the spring wire is not properly integrated into an assembly process.
    [0008] Thus, it is the aim of the present invention to create a spring bearing arrangement for a spring that overcomes the disadvantages of the technique previously identified above, which provides a simple arrangement of a spring insert for the spring, while the process of arrangement, in particular, in an assembly process to build a bearing arrangement, must be integrated without time delay.
    [0009] This objective is achieved on the basis of a spring bearing arrangement according to the present invention. Advantageous embodiments of the invention are specified in the embodiments. Description of the Invention
    [00010] The invention comprises the technical teaching that an adhesive is applied between the spring and the spring insert, with the result that the connection of the spring insert relative to the spring presents a glued connection.
    [00011] The idea of forming a bearing arrangement, according to the invention, is to create a joint material between the spring and the spring insert, which can be easily manufactured and incorporated without adding additional time to the assembly process. of bearing arrangement. Simply applying an adhesive to the spring and/or spring insert results in an extremely simple process to create a bonded joint between the spring and the spring insert without the need to especially select the material to create a bonded joint material. and, without the need for costly intermediate manufacturing steps. Preferably, the adhesive can be applied to the spring insert prior to being assembled over the spring. Alternatively or additionally, the adhesive can be applied directly to the spring.
    [00012] Consequently, the spring insert comprises an elastomer that is designed to be flexible, while the spring support is designed to be movable with a movement of the spring coil. As such, the spring insert may be constructed of an elastically deformable but stable plastic material, and the characteristic curve of the spring is unaffected by the composite of the spring insert with the side end of the spring coil. Due to the co-movement of the spring insert with the spring coil, the rolling spring movement no longer occurs at a point of contact with the spring insert or the spring plate, and the rolling movement is preferably performed between the spring insert and the spring plate.
    [00013] With particular advantage, an adhesive hardened at room temperature can be applied. This creates an additional advantage that the adhesive joint between the spring and the spring insert does not have to undergo any additional processes in order to complete the adhesive joint. Once the adhesive is applied between the spring and the spring insert, the composite generated from the spring and the spring insert can be processed to build a spring system, for example, from a spring frame of a vehicle chassis. The room temperature hardened adhesive can take place during the assembly process or, before the end of the spring system for the vehicle chassis.
    [00014] The spring may have a first end preferably facing the lower end of the vehicle axle, and a second end preferably facing the upper end of the spring dome, while the spring insertion arrangement is provided at least at the first and/or second end of the spring. The spring-in-spring insertion arrangement with the adhesive gasket is preferably carried out at the first end, pointing towards the lower end of the vehicle axle of the spring, because at that end there is a greater effect on the impurities of the bearing arrangement. In particular, the bearing arrangement with a spring plate can collect sand and contaminants such as sand, which can induce an abrasive effect on the spring, where the spring and spring insert are not joined materials. However, the above mentioned advantages of the adhesive joint between the spring insert and the spring can also be applied at the second end, preferably pointing towards the spring dome of the upper end of the spring.
    [00015] The spring insert can be formed as a ring and can extend over an angle of at least 180°, preferably of at least 270° and in particular up to 360° or more. If the angle is less than 360°, then the spring insert is designed in the form of an open ring, and is presented, for example, with a 180° angle in the shape of a crescent. If the spring insert extends around a central geometric axis with an angle of 360° for example, this can be realized as a ring with. Thus, a first end area of the spring insert rests on the spring plate, and the second end area of the spring insert also moves with the spring coil of the spring.
    [00016] Advantageously, the spring insert has a rectangular base cross section that is constantly realized, in particular on the annular circumference. The rectangular base cross section can be embodied with a circumferential recess, the recess in particular having a semicircular base cross section. The spring coil can be glued to the semicircular base cross section, while the rectangular base cross section of the spring insert can extend at least halfway through the spring insert.
    [00017] Furthermore, the bearing arrangement may include at least one spring plate, in which preferably the end of the first spring is received, in which the spring insert, in particular, is disposed between the spring coil of the end side and a spring plate contact surface. Due to the rectangular base cross section of the spring insert, the spring insert may feature a bottom that allows the spring insert to roll over the spring plate contact surface where the spring is compressed. Alternatively, the base cross section of the spring insert may be variably projected over the annular circumference, and the spring insert may, for example, have a flat surface over the entire circumference of the spring insert seated in the spring plate. The upper side may, for example, have a circumferential recess with an inclination corresponding to the inclination of the spring coil. With a deflection of the spring and thus with the movement of the spring coil on the spring plate, a compression of the spring insert can occur, so that neither between the spring coil and the spring insert, nor between the spring insertion and the spring plate of a relative movement, in particular, a rolling movement can take place.
    [00018] The bearing arrangement can be part of a suspension system, in particular a suspension structure of a vehicle chassis, in which the helical compression spring is preformed. In particular, a damper can be guided through the helical compression spring, which is arranged concentrically or eccentrically to the rotational axis of the helical compression spring. In particular, the spring plate can be joined to the damper, and the helical compression spring can be supported by the lower side end against the spring plate and the upper side against a corresponding mounting arrangement.
    [00019] If the spring is mounted in the suspension system of a vehicle chassis, a compression pre-strain can be introduced into the spring, whereby the adhesive is hardened under the effect of compression pre-strain. Thus, a particular advantage is achieved that the hardened adhesive between the spring and the spring insert does not require a separate process step for the hardened adhesive and the spring compound, and the spring insert can be further processed even if the adhesive is already applied to the joint but is not yet hardened. Hardening is particularly advantageous under the spring compression pre-strain in the spring system, during which time pressure is applied facially between the joint to create a strong adhesive joint. Alternatively, the composite of the spring and spring system can harden without compressive pre-tension, for example, in an appropriate device.
    [00020] The object of the present invention is further achieved by a method for forming a bearing arrangement for a spring, in particular for a spring of a vehicle chassis, with at least one spring insert, wherein at least one part of a spring coil of the spring is received, while the spring insert comprises an elastomer and is designed to be flexible, while the spring insert is designed to be movable with a movement of a spring coil in that the method comprises at least the steps of disposing an adhesive between the spring and the spring insert, assembling the spring insert relative to the spring and hardening the adhesive. After assembling the spring insert relative to the spring, a preload spring can be applied to the spring so that hardened adhesive occurs under the preload spring.
    [00021] With the process, according to the invention, a bearing arrangement can be provided for a spring, in particular for a spring of a vehicle chassis, in which an adhesive is applied between the spring and spring insert, so that the joint between the insert and the spring has an adhesive joint. The particular advantage of the method according to the invention is that the adhesive can harden under the applied preload spring, and the hardening of the adhesive does not require a separate manufacturing step.
    [00022] In particular, before applying the adhesive on the spring insert, the contact surface of the spring insert, on which, the adhesive to be applied, can be activated. Preferably, the surface can be activated in a peripheral recess of the spring insert, in which the spring coil of the spring is glued. Alternatively or additionally, the surface of the spring coil can be activated in order to achieve greater adhesive force on the surface of the spring coil. Preferably, activation can take place at room temperature, so no auxiliaries must be provided to heat the adhesive joint of your production.
    [00023] The bearing arrangement spring can be designed as a helical compression spring and can be axially preloaded to form a vehicle chassis frame with a compression pre-strain, where the adhesive is hardened under the effect of compression pre-tension. Preferred Mode of Invention
    [00024] Additionally, measures of improvement of the invention are shown, in detail below, together with the description of preferred embodiments of the invention with reference to the figures. The example shows: Figure 1 an embodiment of a bearing arrangement for a spring in perspective view before placing the spring insert for the spring, Figure 2 a view of a spring with a spring that joins the spring insert with a gasket, in accordance with the present invention, Figure 3 is a perspective view of the spring insert for forming a bearing arrangement for a spring and Figure 4 is a base cross-section seen from the base of a spring insert, in accordance with Figure 3.
    [00025] In Figure 1, a bearing arrangement 1 of a spring 10 is shown. The spring 10 forms, together with a damper 17 which is guided through the spring 10, the damper spring unit of a spring structure for a vehicle chassis. The spring 10 shows a first end, facing a lower end of a vehicle axle, and a second end facing an upper end of a spring dome, while the spring insertion arrangement 11 is exemplified at the first end. spring 10. Spring insert 11 is shown in an unassembled state, and may be adhered to mount over a portion of spring coil 10' of spring 10. Spring insert 11 extends over the central axis of the spring. spring 10 at an angle of about 360°, such that spring insert 11 is designed as a slit ring.
    [00026] The spring 10 is supported by the spring insert 11 in a spring plate 15, and the spring plate 15 has a contact surface 16, on which the spring insert 11 can rest. If the spring 10 is fixed to the composite with a spring frame, the spring 10 is supported by the spring insert 11 against the contact surface 16 of the spring plate 15. The spring plate 15 is therefore disposed at the lower end of the shock absorber 17.
    [00027] To create with an adhesive with a joint material joined between the spring 10 and the spring insert 11, according to the present invention, the adhesive 12 is applied, for example, to the side joint of the spring insert 11. If the spring coil 10' is brought into contact with the spring insert 11, the adhesive 12 can be hardened and the spring insert 11 has a gasket material joined with the spring coil 10' of the spring 10.
    [00028] At the second upper end of spring 10, which points towards a dome spring, spring 10 is supported against another spring plate 18. Spring plate 18 can be constructed with an elastic element 19, executed by example, as a rubber plug, and a top mounting arrangement 20, a spring pack arrangement, to be installed on the vehicle housing the spring. The upper mounting arrangement 20 may include an upper dome frame to allow rotation of the structure with spring 10 and damper 17. The arrangement shown is commonly used for a front axle of a motor vehicle, wherein the arrangement of bearing 1, according to this invention, can be used for an adhesive joint between the spring 10 and the spring attachment 11 and also for the spring seat 10 for the rear axle of a motor vehicle.
    [00029] In Figure 2, the bearing arrangement 1 with a joint between the 10 and the spring insert 11, according to the present invention, is explained in detail. Spring insert 11 is shown in mating arrangement with spring coil 10‘. Spring insert 11 extends at an angle of 360° about the central axis of spring 10 and builds a slit ring. Due to the joint material joined between the spring insert 11 and the spring coil 10', the spring insert 11 has an inclination corresponding to the inclination of the spring coil 10'. In the operation of spring coil 10', spring insert 11 can also move with spring coil 10', and a rolling motion can take place between spring insert 11 and spring plate 15 (see Figure 1), whereas between the spring coil 10' and the spring insert 11 there is no movement relative to the spring housing 11.
    [00030] The base cross section of the spring insert 11 features a base section 14, which is constant and unchanging over the annular circumference of the spring insert 11. The rectangular base section 14 is additionally realized by a circumferential recess 13 , in which the spring coil 10' is glued. Recess 13 is shown with a recess with a semicircular cross section, so that the spring coil 10' is slightly reached in the middle of the recess 13 of the spring insert 11.
    [00031] Figure 3 shows a perspective view of the spring insert 11, which extends at an angle of approximately 300° around a central spring axis, which is not shown in detail. The spring insert 11 has a cross-sectional base section 14 which presents, on the upper side, pointing to the side of the spring 10, a circumferential recess 13. On the opposite side pointing downwards, the spring insert 11 has an area 21 which is projected. flat and serves as a supporting surface against the contact surface 16 of the spring plates 15, see Figure 1.
    [00032] In the circumferential recess 13 by way of the example, an adhesive 12 is applied, which is formed as an adhesive 12 cured at room temperature. If the spring insert 11 with applied adhesive 12 with the spring coil 10' of the spring 10 is brought into contact, the joint material joined between the spring 10 and spring insert 11 can be made with the present invention.
    [00033] Figure 4 shows an additional view of the spring insert 11 with the base cross section 14, with the circumferential recess 13 placed on the upper side and 21 on the lower side. The surface of the spring insert 11 in the circumferential recess 13 can form an activation area 22, which is indicated by a number of arrows.
    [00034] The invention is not limited in its design to its preferred embodiments described above. On the contrary, a number of variations, which make use of the presented solution, even if generally for different models, is possible. All features and/or advantages resulting from these embodiments, descriptions, or drawings, include design details, spatial arrangements, and method steps, and may by themselves or in different combinations be substantial to the invention.
