Definitions
- the invention relates to an attachable to rubber tires of vehicles, increasing the claw-ability of the driven wheels, an anti-slip construction, which is used on critical routes for the quick release of snow-covered, icy roads and vehicles to improve their driveability.
- bracket profiles encompass the side surfaces of the rubber tire, compress them, and the bracket profiles fastened to the tire in this way are tensioned against one another on the outside of the wheel by tension springs.
- This type of attachment of the bracket profiles is the does not meet practical requirements with sufficient certainty, because the bracket profiles slip during use and can migrate on the bead of the rubber tire.
- bracket profiles are tensioned in this solution by inserting a tension spring through flexible tension elements on the tread of the rubber tire.
- This is the disadvantage of this solution; the flexible tension element can only be subjected to tension, a radial removal of the bracket profiles from the tread of the rubber tire is not possible.
- DE-A-2 400 831 describes a bracket construction in which the shaft of the bracket profiles is rotated in pairs in a central hub part through 90 °, as a result of which the construction can be easily and quickly placed on the rubber tires.
- the shafts of the bracket profiles protruding into the hub part are provided with toothed rack teeth and can be moved in the radial direction by means of centrally arranged toothed wheels.
- the advantage of this solution is, among other things, that not only can it be clamped onto the tread of the rubber tire, but also can be dismantled easily and quickly by simultaneous radial movement of the bracket profiles.
- bracket profiles are pressed onto the tread of the tire in a similar arrangement to that described above, which further improves the ability of the wheel to grip. What is interesting about this solution is that the size of the bracket profiles can be adjusted according to the profile width of the tire.
- the shaft of the bracket profiles provided with toothed rack teeth can be removed from the central hub part, as a result of which the space requirement of the device is reduced when it is stored.
- the stirrup profiles guided in a radial direction are pressed onto the surface of the tire by springs and an aid is used to hook these springs.
- a deficiency of this solution is that the clamping force of the bracket profiles changes depending on the wheel diameter, and as a result their support, fixation on the tread is not as secure as that of the bracket profiles guided by a rack and pinion connection.
- a central tensioning structure is used for the radial movement of the stirrup shafts provided with rack teeth and for mounting on the tires, which contains a pre-tensioned compression spring and a pawl mechanism.
- This device is easier to use than the previous solutions, and the fixation of the bracket construction is also more secure than that of the former.
- devices which, mounted on the wheel and fastened, for example, to the screws holding the wheel, comprise the tire with rows of chains lying loosely on the tread.
- the looseness of the chain rows on the tread is a prerequisite for normal function, but precisely because of this their effectiveness does not even come close to that of the snow chains.
- the effectiveness of the conventional snow chains results from the fact that, in the mounted state, they form a closed arrangement stretched onto the tread, part of which is always connected to the road surface while the wheel is rotating.
- a slip-resistant construction that can be used in accordance with the road conditions can be expected to be more effective or more effective than the snow chains if the method of use is chosen correctly, but its handling should also be faster and more convenient than that of the snow chains in the latter case.
- the object of the invention is therefore to provide a slip-resistant construction that meets the requirements mentioned, which firmly spans the entire tread of the tire in the mode of use ensuring maximum effectiveness and which always touches the road surface with part of the tire.
- the invention is based on the finding that a closed arrangement similar to the conventional snow chains, stretched over the rubber tires, can also be achieved with a strap-chain combination which is quicker and more convenient to handle than the snow chain, if for the fine adjustment of the length of the between the strap profiles insertable chain links, their dimensionally correct design and for ensuring that the optimal tightness of the chain links resting on the tread of the tire can be ensured by pressing the bracket profiles on the tires, a solution which meets the practical requirements is found.
- the anti-slip bracket construction according to the invention contains bracket shafts which are provided with rack teeth and are connected to the gears of a central clamping hub, furthermore connected to the bracket shafts, allowing radial movement in the direction of the clamping hub and, attached to the sliding units, through the central clamping hub onto the tread by the central clamping hub of the tire can be clamped bracket profiles.
- An important feature of the construction is that by rotating the adjusting disc of the central clamping hub, the bracket profiles which can be moved in the radial direction can be simultaneously clamped onto the tire or removed from the tread of the tire at the same time.
- the sliding units arranged between the bracket profiles and the bracket shafts allow the bracket to be shortened periodically while the wheel is rotating, ie the bracket profiles are able to follow the deformation resulting from the flattening of the rubber tire without harmful side effects.
- the stated object was achieved in accordance with the invention in accordance with the invention in that the non-slip construction is provided with rows of chains which can be inserted between the bracket profiles and which end hooks on the parts resting on the side surface of the tire of the bracket profiles attached chain holder tabs can be hooked in, the end hooks are provided at least at one end of the chain holder tabs with elements preventing hooking, for example springs preventing hooking out, and the part of the tire resting on the tread of the tire inserted between the bracket profiles by means of the chain holder tabs
- Chain rows are equipped with units suitable for fine adjustment of the length of the chain rows and also increasing the ability of the wheel to claw, consisting of ribs and connecting plates.
- the chain links of the chain series are made of high-strength material, expediently from patented spring wire, and their shape guarantees a safe, tilt-free resting on the tread of the tire.
- the chain holder plates are fastened at those definable points of the parts of the bracket profiles lying on the side surface of the tire, to which the in the Chain holder plates are attached to the chain rows when the bracket profiles are tensioned on the tire, lie with optimal tension on the tread of the tire, however, when the bracket profiles have been moved radially away from the tread, the chain rows are in a correspondingly loose state to be able to enter End hooks of the chain holder straps can be hooked in or unhooked from these.
- the units consisting of ribs and connecting plates are suitable for fine adjustment of the length of the chain rows and also increase the claw-ability of the wheel, if the chain rows are in the state attached to the tire, are connected to one another by connecting chains resting on the tread, and at a certain angle with respect to the axis of symmetry of the chain rows Arranged retaining chains are connected to the end hooks of the chain bracket plates
- pairs of holes provided with threads on the ribs, while parallel rows of holes are formed on the connecting plates are at a certain pitch (t) from each other and within a parallel row of holes the individual holes are also at a pitch (t) from one another such that the hole distribution of adjacent parallel rows of holes is shifted by half a pitch (0.5 t) from each other, and in the threaded pairs of holes on the ribs, the distance between the holes is equal to the pitch (t) of the parallel rows of holes, while the distance between the pairs of holes is one and a half pitch (1.5 t), so that four threaded holes each the other n Form ribs with threaded hole pairs, two diagonally arranged threaded holes each with the holes in the parallel hole rows of the connecting plates in the positions corresponding to half a pitch distance (0.5 t)
- the chain links resting on the tread of the tire of the chain rows insertable with the chain holder plates between the bracket profiles have symmetrical features in which the chain links in the tangent plane of the support and in the planes parallel to the tangent plane are symmetrical, but are asymmetrical in the plane perpendicular to the tangent plane of the support and in the planes parallel to it
- FIG. 1 shows a side view of an anti-slip construction according to the invention in the state mounted on the tires
- FIG. 3 illustrates the construction of a chain holder plate with hooked chain rows, on a larger scale than FIG. 1 4 shows a side view of the connecting chains connecting the ribs to one another,
- Fig. 7 shows the side view of the unit shown in Fig. 6 while
- Fig. 8 illustrates in top view the configuration of the chain links ensuring a secure, tilt-free support and their connection to one another.
- Fig. 1 the anti-slip construction according to the invention is shown in a mounted state on a tire.
- the bracket shafts 2 which engage in the gearwheels la of a central clamping hub 1 and are provided with a toothed rack toothing 2a, which in the direction of the clamping hub 1 allow movement in the radial direction to allow sliding units 3 and the bracket profiles 4 fastened to the sliding units 3 to be pressed onto the rubber tires 8 .
- the end hooks 6c of the chain bracket plates 6 fastened to the bracket profiles 4 with the chain rows 5 suspended in them, which cover the tread 8b of the tire 8 on the sections lying between the bracket profiles 4.
- Fig. 2 the top view of the anti-slip construction, the structure of the chain rows 5 is illustrated. It can be seen that in the chain holder plates 6, the free ends of retaining chains 5 a of the chain rows 5 are suspended, while the other end of the retaining chains 5 a is connected to ribs 5 b.
- the ribs 5b are attached to connecting plates 5c at a variable distance from one another.
- the retaining chains 5a are connected to the outer ribs 5b at a certain angle with respect to the axis of symmetry of the chain rows 5, while the inner ribs 5b are connected to one another by connecting chains 5d parallel to the axis of symmetry of the tire 8.
- the number of chain links of the retaining chains 5 a and the connecting chains 5 d depends on the tread width of the tire and its outer diameter and can differ from the example shown in the drawing.
- FIG. 3 which illustrates the chain holder plates 6, a chain holder plate 6a and a spring 6b preventing a detachment with a protective plate 6d can be seen in a riveted state; the assembled in this way Chain bracket tabs 6 are fastened with hexagon screws to the parts 4a of the bracket profiles 4 resting on the side surface 8a of the tire 8. It can be seen that the end hooks 6c of the chain holder plates 6 on the two sides of the chain holder plate 6a are designed differently.
- Fig. 3 also shows how the free end links 7 of the retaining chains 5 a with the end hook 6c are connected.
- the connecting chains 5d of the chain rows 5 are shown in a side view in FIG. 4 and in a top view in FIG. 5. It can be seen how the normal chain links 9 are connected to the ribs 5b and how the twisted chain links 10 are connected to one another or to the normal chain links 9.
- the connecting chains 5d according to the exemplary embodiment each consist of four chain links, two of which are normal chain links 9 connected to the ribs 5b and two twisted chain links 10 arranged opposite one another and connected to one another. If the length of the connecting chains 5d corresponding to the dimensions of the rubber tire 8 deviates from the exemplary embodiment, this can be compensated for by changing the number of normal chain links 9.
- Each connecting chain 5d contains two twisted chain links 10 arranged opposite one another and connected to one another.
- FIG. 6 shows the ribs 5b and the connecting plates 5c in the assembled state from the tread 8b of the rubber tire 8, while FIG. 7 shows the same assembled unit in a side view.
- the ribs 5b are fastened to the connecting plates 5c with four conical head screws 11 each.
- the connecting plates 5 c parallel rows of holes 12 are formed which are spaced apart by the pitch t.
- the individual holes also have the pitch t, so that the hole distribution of adjacent parallel rows of holes is shifted by half a pitch (0.5 t).
- the position of the holes is indicated in FIG. 8 by the position symbols a, b, c and d.
- ribs 5b there are two threaded pairs of holes 16, the threaded holes of which are at a distance of one division distance (t) from each other by one and a half division distances (1.5 t). From Fig. 6 is It can be seen that of each four threaded holes which form threaded pairs of holes on the ribs 5b, two diagonally arranged threaded holes can be made to coincide with the holes in the parallel rows of holes 12 in several positions. At the point where the holes were made to coincide, the ribs 5b and the connecting plates 5c can be screwed together.
- the fastening point of the ribs 5b on the connecting plates 5c can be changed in steps of half a division unit (0.5 t), which enables the length of the chain rows 5 to be finely adjusted.
- the left rib 5b is shown in position b in FIG. 6, but the conversion into position c is also indicated by a broken line. It can be seen that in the case of a conversion taking place by half a division distance, the conical-head screws 11 come into a diagonal of opposite inclination.
- Fig. 8 shows the normal chain links 9 and their connection to each other. It can be seen how the bent back double tail part 15 of the normal chain link 9 is inserted through the head part 14 of the following normal chain link 9.
- the wide projection of the head part 14 allows a firm, practically tilt-free resting on the tread 8b of the tire 8.
- the normal chain links 9 are arranged on the tread 8b in such a way that their head part 14 coincides with the tangent plane of the support, as a result of which the normal chain links 9 in the tangent plane of the support and the planes parallel to the tangent plane are of symmetrical shape.
- the anti-slip construction according to the invention is expediently explained together with the explanation of its handling. It should be noted that the anti-slip construction according to the invention can be used in several uses to improve the ability of the wheels to claw, in order to adapt to the different road conditions characterized by snow and ice. The types of use differ from one another in the number of chain rows mounted together with the bracket construction on the wheel.
- the non-slip construction is at least two permanent chain rows 5 mounted on the tire 8
- the ability to claw is improved to 50% of the tread 8b of the tire 8, but at the same time the assembly and disassembly can be carried out very quickly or a slightly ascending section of the path that is covered by a layer of snow that is at least 5 cm thick
- the anti-slip construction On very steep or more than 10 cm thick sections of snow or during continuous use, the anti-slip construction must be used in its entirety, i.e. it must be provided with both additional chain rows 5. After the first additional chain row 5 of the anti-slip construction has been created, the Vehicle are moved a little so that the second additional chain row can also be put on. If the entire anti-slip construction is used, the tire 8 is enclosed by the chain rows 5 in an arrangement of corresponding tautness, and a chain row 5 or a profile 4 is standing while this The wheel turns, always in contact with the road surface.
- the anti-slip construction offers maximum effectiveness and safety in this form of use, but even in this case it is much easier and quicker to handle than the snow chains
- the anti-slip construction according to the invention must be tried on the tires before use, so that the length of the chain rows can be checked and adjusted.
- the length of the permanent chain rows 5 must be set so that they are neither too loose nor too tight. If the chain row 5 is too tight , it prevents the bow profile 4 from resting on the tread 8b of the tire 8, which interferes with the correct functioning of the anti-slip construction and can lead to harmful deformations during use
- the length of the chain rows 5 is adjusted by loosening the screw connection of the ribs 5 and the connecting plates 5c and screwing them back in the new position.
- the additional chain rows 5 must be set to the same length so that they can be replaced if necessary
- the ratchet mechanism of the clamping hub 1 is set to the “open” or “closed” operating mode and the adjusting disc 1b is rotated.
- the rotation of the adjusting disc 1b results in the rotation of the gearwheels 1b a movement of the bracket profiles 4 in the radial direction, this makes it possible to press the bracket profiles 4 onto the tires 8 or to loosen them therefrom
- the permanent chain rows 5 are permanently suspended from the bracket profiles 4 when the chain bracket plates 6 are mounted on the bracket profiles 4.
- the retaining chains 5 a of the supplementary chain rows 5 can, depending on the type of use, be pushed sideways by pressing the springs 6b preventing the unhooking into the End hooks 6c of the chain holder plates 6 are snapped in or released from the end hooks 6c.
- the springs 6b preventing the unhooking jump back onto the side surface of the chain holder plate 6a after the chain link has snapped in, thus closing the end hooks 6c and thereby preventing them from working together with the wheel rotating anti-slip construction a random unhooking of the chains 5 a
- bracket profiles 4 and the chain rows 5 are able to follow the deformations resulting from the flattening of the tire without harmful side effects Ensure wheels
- the advantages of using the anti-slip construction according to the invention are equally significant compared to the known snowbugs and the conventional snow chains.In comparison with other snowbow devices, the greater increase in the ability to claw and the rounder, more uniform running of the wheel are to be emphasized the advantage of more convenient and faster manageability, it can also to be placed on a vehicle that has already got stuck, while the snow chains have to be put on beforehand because they cannot be fitted onto the wheels of a stuck vehicle.
- Another advantage of the anti-slip construction according to the invention, measured against all known solutions, is that the mode of use corresponds to the road conditions can be chosen accordingly, using the effortless effort and inconvenience
