    Chain for mounting on a vehicle tire
    The invention relates to a chain for mounting to a vehicle tire, in particular an anti-skid chain, wherein the chain is constructed of chain strands chain network with a central region which is arranged in the mounted state of the chain on the tread of a vehicle tire, an inner edge region, which with an inner Support strand is connected, and an outer edge region, which is connected to an outer support strand having, wherein the central region between the inner and the outer edge region and in the assembled state of the chain, the inner edge region of the chain on a vehicle-facing inside of the Vehicle tire is arranged and the outer edge region is arranged on a side facing away from the vehicle outside of the vehicle tire. The invention also relates to a chain strand for such a chain.
    A variety of chains are known from the prior art, which are intended to prevent the slipping particular driven wheels of a motor vehicle on a fixed and unpaved ground. Such anti-skid chains find use, for example, in work vehicles that are used on slippery or soft ground such as mud, snow and frozen ground.
    The anti-skid chains usually have a running net, which is arranged in the assembled state on the tread of a vehicle tire. The treadmill is usually connected via shoulder chains on the inside and outside with holding strands, which serve to brace the running net or the chain. Such chains are usually realized with chain strands of straight or twisted chain links of different cross-section The holding strands can be chains, wire ropes or similar solutions.
    Known solutions are on the one hand continuously made with turned chain links, for example, to have the smallest possible space or reduced order size. However, this affects the traction properties of the chains. Chains with straight chain links, on the contrary, take up a lot of space and damage to vehicles may occur during use. -2- PI2530
    It is therefore an object of the invention to provide a chain which overcomes the above-mentioned disadvantages of the prior art
    This object is achieved by an anti-skid chain mentioned above according to the invention in that the central region is formed at least predominantly of straight chain links and the inner edge region is formed of turned chain links
    The invention makes possible a chain which, on the one hand, has good traction properties on the one hand due to the embodiment of the central region of the chain net and, on the other hand, has a reduced application dimension on the inside of the vehicle tire facing the vehicle (ie the vehicle tire inner side). The straight links of the central region of the chain network, which functions as a running net and can be designed with different geometries of webs, transmit traction force while the turned chain links of the inner edge region serve to fasten or tension the chain. The chain links of the outer edge region can in principle be of any desired design. for example, also with straight chain links.
    In the solution according to the invention, conventional chain links are used, which are designed essentially in the shape of an oval with an inner opening and have two longitudinal legs arranged substantially parallel and which are connected to one another via two substantially semicircular ends. Under straight chain links here chain links are understood, the longitudinal leg clamp on a plane, wherein in a chain connection in each case a standing connected to a lying chain link standing and lying here to understand in terms of a vehicle tire surface, wherein at a horizontal link from the longitudinal legs on strained plane parallel to such a surface, while in a standing chain link, the plane spanned by the longitudinal limbs normal to such a surface.
    The longitudinal legs of twisted chain links extend substantially in opposite directions away from the vehicle tire surface. The opposite ends of the links are twisted against each other. The twist angle can vary depending on the version. -3- PI2530
    Basically, the chain links used can be turned by the property or have straight different cross sections. The property of the rotated or straight design is independent of the selected cross section, In addition to a circular cross section, for example, D-shaped or polygonal cross-sections are possible. Conveniently, at least in the chain links of the central region of the chain network are chain links with square cross-section. In a further advantageous embodiment of the invention, the chain links of the inner edge region and / or the chain links of the outer edge region are formed as chain links with square cross-section. The square cross-section that is a substantially square or rectangular cross-section is characterized by particularly good traction properties.
    In a variant of the invention, the chain net has inner shoulder chains with a first inner shoulder chain section and a second inner shoulder chain section, wherein the first inner shoulder chain section is in the central region of the chain net and the second inner shoulder chain section is in the inner edge region of the chain net. Such inner shoulder chains can be made of two independent chain strands.
    In a first such variant, the first inner shoulder chain portion is formed as at least one chain chain of straight chain links and the second inner shoulder chain section is formed as at least one strand of twisted chain links wherein the chain strand of the first inner shoulder chain portion and the chain strand of the second inner shoulder chain portion via at least one connecting member connected to each other. The connecting member may be designed, for example, as a circular member, but in principle in various ways. The chain links of the first and second inner shoulder chain section are preferably formed as chain links with square cross-section
    In a second such variant of the invention, the inner shoulder chains each consist of a continuous, unbranched chain strand, wherein the chain links in the first inner shoulder chain section are straight and the chain links are rotated in the second inner shoulder chain section. The chain links of the inner shoulder chain sections are therefore identical to each other in terms of material, shape and cross section - in the production of such inner shoulder chains an identen chain strand is used whose chain links in a section (just in the mounted state on the vehicle tire inner side comes to rest ) to be turned around.
    When the chain links are rotated, the opposite ends of the chain link are rotated by a certain angle of rotation against each other. This then also results in a deformation of the longitudinal limbs of the chain link. The twist angle can in principle be arbitrary and, for example, between 1 ° and about 100 ° or more. In principle, the twisted chain links in the present invention are all twisted by the same angle of twisting within certain tolerances. According to a variant of the invention, the twist angle of the turned chain links of the inner edge region increases in the direction of the inner retaining strand. Thus, while the first, immediately adjacent to the straight chain links chain link is rotated by a small angle of rotation, the twist angle increases in the direction of the inner support strand. The increase can be gradual or in jumps. For example, the twist angle may increase slightly with each link, but the angle may change in groups, such that, for example, a certain number of links have the same twist angle and the adjacent set of links has a larger twist angle, and so on. Any variants are possible here, which are characterized by the fact that the angle of rotation increases in the direction of the inner support strand out. In principle, of course, the reverse embodiment is possible, namely that the angle of rotation decreases in the direction of the inner support strand out. In a further possible variant, the twist angle increases in the direction of the inner support strand first to and then again, or vice versa.
    The above object is also achieved by an aforementioned chain strand according to the invention that the chain strand consists of at least a first chain strand section with twisted chain links and at least one adjoining second chain strand section with straight chain links wherein the chain strand preferably consists of several such chain strand sections which are arranged alternately are. Such a chain strand can serve, for example, for repairing a chain described above. The chain links can in principle have any cross-section. Conveniently, the chain links have a square cross section at least in the second chain strand section. But there are also variants conceivable in which only the members of the second chain strand section or at all -5- PI2530
    Chain links of the chain strand have a square cross-section. In the case of the turned-oil chain links, all chain links can have the same twist angle, but also variants as described above, where the twist angle increases or decreases over the strand section, are possible.
    The chain strand sections each directly adjoin the adjacent chain strand sections or at least one connecting link is arranged between adjacent chain strand sections. In the first variant described, therefore, the individual chain strand sections are immediately adjacent to one another - a chain strand with identical chain links can be used, wherein the chain links of the first chain strand section can be rotated during production. In the second variant, in principle differently designed chain strand sections - arbitrarily executed in terms of material, material thickness, shape and cross-section - are connected to form a chain strand according to the invention.
    In the following the invention will be explained in more detail by means of a non-limiting embodiment, which is illustrated in the drawing, in which:
    Fig. 1 is a plan view of a chain according to the invention;
    Fig. 2 is a fragmentary view of a first variant of the chain according to the invention;
    Fig. 3 is a fragmentary view of a second variant of the chain according to the invention; 4 shows a first variant of a chain strand according to the invention; and FIG. 5 shows a second variant of a chain strand according to the invention.
    In the figures, for reasons of clarity, the same elements are provided with the same reference numerals.
    1 shows a chain 1 according to the invention in a schematic plan view. For better understanding of the chain 1 in the mounted state, the relevant areas of a vehicle tire, namely the tread 3 with the middle straight 100, the vehicle facing the inside of the Fahrzeugreifais (vehicle tire inner side 300) and the The outside of the vehicle tire (vehicle tire outer side 400) facing away from the vehicle and the inner tire 200 and the outer tire edge 500 in FIG. 1 are shown. The inner tire edge 200 separates the running surface 3 and the vehicle tire inner side 300, while the outer tire edge 500 separates the running surface 3 and the vehicle tire outer side 400. The tire edges 200, 500 are not abrupt edges depending on the type of tire but continuous transitions between the running surface 3 and the vehicle tire inner surface. 300 or -outside 400.
    The chain 1 has a chain network 2 constructed from chain strands. The chain network 2 comprises a central region 20, which is arranged in the mounted state of the chain 1 on the tread 3 of the vehicle tire. The middle region 20 is located between an inner edge region 21 and an outer edge region 22.
    The inner edge region 21 comes in the assembled state of the chain 1 on a vehicle facing the inside of the vehicle tire, the vehicle tire inner side 300 to lie. The inner edge region 21 is connected to an inner support strand 5, wherein the inner support strand 5 is in the mounted state on the vehicle tire inner side 300
    The outer edge region 22 comes in the assembled state of the chain 1 on a side facing away from the vehicle outside of the vehicle tire, the vehicle tire outer side 400, to lie and is connected to an outer support strand 7. The outer support strand 7 is in the mounted state on the vehicle tire outer side 400. About the holding strands 5.7, the chain 1 can be stretched and thus fastened to the vehicle tire.
    In the central region 20 of the chain network 2 traction cords 12 are arranged in the illustrated embodiment, which consist of straight chain links and in the assembled state of the chain 1 are substantially parallel to the middle straight 100 of the tread 3. The connection of the chain network 2 with the holding strands 5, 7 via shoulder chains 4, 6. Inner shoulder chains 4 connect the traction strands 12 with the inner support strand 5 on the vehicle tire inner side 300, while the connection to the outer support strand 7 on the vehicle tire outer side 400 according to the outer Shoulder chains 6 takes place. The holding strands 5, 7 can be designed arbitrarily, for example as a tensioning chain or tensioning cable. -7- P12530
    The connection of the shoulder chains 4, 6 to the holding strands 5, 7 by means of connecting elements 13, which are designed as ring members in the illustrated embodiment. Here, too, are any other known embodiments, e.g. Hook or similar, possible. Of course, the illustrated Kettermetz variant is only one of several variants known to the person skilled in the art.
    The inner shoulder chains 4 have a first inner shoulder chain section 41 and a second inner shoulder chain section 42, wherein the first inner shoulder chain section 41 is located in the central region 20 of the chain net 2 and the second inner shoulder chain section 42 is located in the inner edge region 21 of the chain net 2.
    The outer shoulder chains 6 may also consist of several sections, but will not be discussed further in the following. The traction strands 12 and the outer shoulder chains 6 consist of straight chain links. In the case of straight chain links, the longitudinal limbs of the chain link run essentially parallel to one another and span one plane. In the mounted state usually lying with upright chain links alternate - in lying chain links, the above-mentioned plane is parallel to the tread 3 of the vehicle tire, while the standing chain links are arranged normal to the tread 3.
    The straight chain links allow particularly good traction characteristics of the chain 1, in particular in conjunction with a matching chain link cross-section, which may for example be designed as a square cross-section. In the illustrated embodiment, the traktionsgebende running net of the traction strands 12 and located in the central region 20 of the chain network 2 chain links of the outer 6 and inner shoulder chains 4 (ie the first inner shoulder chain portion 41). In principle, other known to the expert runnet geometries are possible, as far as according to the invention at least those in the inner edge region 21 of ordered chain links are formed from.
    The inner shoulder chains 4 are inventively designed such that it is at least in the second inner shoulder chain portion 42, which is arranged in the mounted state of the chain 1 on the vehicle tire inner side 300, formed of turned chain links. The first inner shoulder chain portion 41, which is arranged in the assembled state on the tread 3 of the vehicle tire (and according to the embodiment shown is the -8- P12530 middle portion 20 belongs), consists of straight chain links, but may of course also consist of twisted chain links. The second inner shoulder chain portion 42 with the twisted chain links is designed so that in the mounted state on the inner tire edge 200 already twisted chain links come to rest. The second inner shoulder chain portion 42 begins in the assembled state immediately before the inner tire edge 200. It must be ensured accordingly that in the mounted state, the second inner shoulder chain portion 42 comes to lie with the turned chain links already in this area. The chain links of the shoulder chains 4 preferably also have a square cross section.
    On the one hand, this solution allows particularly good traction properties; on the other hand, the space requirement of the second inner shoulder chain sections 42 on the vehicle tire inner side 300 is particularly low. The straight members act to transfer traction, while the rotated members serve primarily to hold the chain 1 with a reduced amount of application to the vehicle tire inner side 300. Since in the wheel well, or on the vehicle tire inner side 300, usually limited space prevail and a chain 1 with too large order size can lead to damage, the chain 1 according to the invention is particularly advantageous
    In Figures 2 and 3 variants of erfindungsgeinäßen chain 1 and the inner shoulder chains 4 are shown in ausschnittswei ser view.
    Fig. 2 shows the variant described above. The inner shoulder chain 4 is formed of a continuous, unbranched chain strand, the chain links are made identical in shape, material, material thickness and cross section. In the manufacture of a chain strand can be produced with straight chain links, in a subsequent step, the chain links of a portion of the inner shoulder chain 4, which then forms the second inner shoulder chain portion 42 in the assembled state, are rotated.
    The arranged in the mounted state on the tread 3 first inner shoulder chain portion 41 with straight chain links thus goes directly into the disposed on the vehicle tire inner side 300 second inner shoulder chain section 42 with turned chain links over. -9- PI2530
    3 shows a second variant in which the first inner shoulder chain portion 41 is formed as at least one chain chain with straight chain links and the second inner shoulder chain section 42 is formed as at least one chain strand with twisted chain links wherein the first inner shoulder chain section 41 and the second inner shoulder -terkettenabschnitt 42 are connected to each other via at least one connecting member 8. The shoulder chain sections 41, 42 can also be formed in each case from a plurality of chain strands. The connecting member 8 may for example be designed as a ring, of course, any other embodiments of the connecting member 8 are possible, e.g. Hooks, double rings, or similar.
    The two shoulder chain sections 41, 42 are thus designed as separate chain strands which are connected to the connecting link 8. The shoulder chain sections 41, 42 can therefore differ in terms of material, material thickness, cross section and shape.
    In the case of turned chain links, in principle the opposite ends of the chain link are rotated relative to each other by a certain angle of rotation. This then also results in a deformation of the longitudinal limbs of the chain link. The twist angle can in principle be arbitrary and, for example, between 1 ° and about 100 ° or more.
    According to a first variant of the invention, the turned chain links each have the same angle of rotation. According to a second variant, which is not shown in the figures, the twisted chain links have different angles of rotation. For example, the twist angle of the rotated chain links of the inner shoulder chains 4 (or the second inner shoulder chain section 42) increases toward the inner support strand 5. The subsequent to the first inner shoulder chain portion 41 with straight chain links chain link thus has only a small angle of rotation, the angle of rotation then increases in the direction of the inner support strand 5. This increase can be either gradual or gradual. Either thus each chain link has a slightly increased compared to the previous twist angle, or the twist angle increases in groups - a group of, for example, three links has a first twist angle, the next group, also with three or more or fewer chain links then has a order a certain amount increased twist angle. -10- PI2530
    Of course, the reverse variant is also possible, that is to say that the angle of rotation decreases in the direction of the inner retaining strand 5. In another variant, the twist angle first increases and then decreases, or vice versa.
    Apart from the chain 1 described above, the invention also includes separate chain strands as they are used, for example, as shoulder chains 4, 6 use. Such chain strands can be used for example for repair purposes for the above chain 1, but other applications are possible.
    4 shows such a chain strand 9 according to the invention according to a first variant, wherein the chain strand 9 has at least one first chain strand section 10 with twisted chain links and at least one second chain strand section 11 with straight chain links. The two chain strand sections 11, 12 each directly adjoin the adjacent chain strand sections , so that the chain strand 9 can be made, for example, of identical straight chain links, in which case in the production sections of chain links are rotated.
    Although Fig. 4 shows only one chain strand section 11, 12, the chain strand 9 preferably consists of several such chain strand sections, which are arranged alternately. The number of chain links of the individual sections can be arbitrary -the first 10 and the second chain strand section 11 can have the same number or different numbers of chain links.
    5 shows a second variant, according to which the above-mentioned chain strand sections 11, 12 are each separated from each other by at least one connecting link 8. The connecting member 8 may for example be designed as Rmgglied. Such a chain strand 9 can be formed as chain strand sections 11,12 of various types.
