Description
Shackle device for show-shackles mounted periodically on tyres of vehicles The invention relates to a shackle device for show-shackles mounted periodically on tyres of vehicles, which includes a shackle shank and one or more shackle profile connected to the shackle shank, having said shackle shank a contact surface borne at least partly on the shoe of the tyre while the shackle shank has a cogged part serving for the connection to the hub assembly provided with adjusting and fastening mechanism.
During winter periods, a number of solutions aimed at contributing to the traffic safety on snow-covered and icy roads became known. One of them consists of the snow-chain made from chain-links and provided with flexible fastening elements, that are mounted on the driven wheels of vehicles.
The disadvantage of show-chains is that, due to its difficult handling and fastening, they are uncomfortable; therefore, other substituting solutions were developed, i.e. fixed shackle mechanisms fastened on the tyres in order to promote the clinging to the road surface.
A mechanism of this kind is described among others in the patent descriptions US
4.?09.049 and HU '' 10.37'_'.
The common feature of show shackles used at present is, that the part of shackle in contact with the tire shoe that promotes the clinging and the cogged shackle shank connected to the central hub assembly is formed as a single part made preferably of bar-steel, thus ensuring the rigid connection to the hub assembly of the shackle mechanism.
However, the snow-shackles have the disadvantage that, due to their rigid structure, the central hub assembly of the shackle device mounted on the tyre performs an irregular roaming motion as a result of the "flattening" of tyre under the load, which causes a harmful dynamic stresses during progression. As a result of roaming motion, the contact between the shackles and the tyre shoe will be loosened and, with larger and smaller displacement, will be re-established on each revolution of the wheel.

A mechanism of this kind is described among others in the patent descriptions US

The common feature of show shackles used at present is, that the part of shackle in contact with the tire shoe that promotes the clinging and the cogged shackle shank connected to the central hub assembly is formed as a single part made preferably of bar-steel, thus ensuring the rigid connection to the hub assembly of the shackle mechanism.
However, the snow-shackles have the disadvantage that, due to their rigid structure, the central hub assembly of the shackle device mounted on the tyre performs an irregular roaming motion as a result of the "flattening" of tyre under the load, which causes a harmful dynamic stresses during progression. As a result of roaming motion, the contact between the shackles and the tyre shoe will be loosened and, with larger and smaller displacement, will be re-established on each revolution of the wheel.
The phenomena described above and the associated dynamic effects have negative influence on the traveling features of the vehicle and, together with other disadvantages of the fixed shackle design, they also endanger the safety in use which, in turn, is unacceptable in respect of life- and material safety.
A further disadvantage of the fixed shackle design is that the part of shackles in contact with the tyre shoe will be unable to follow the declination of road surface from the horizontal plane and its roughness. In extreme cases, this disadvantage of the rigid shackle structure may lead to the permanent deformation of shackle shanks, or even, breaking of the hub assembly.
The "shackle insertion" described in the patent description HL1 T 55.684 aimed at reducing the imperfection found, however, without obtaining complete solution.
The invention is aimed at eliminating the insufficiencies of known structures provided with fixed shackle shanks, and developing a show-shackle that enables the shackle profiles to follow the deformation of tyre during travel without any harmful effect, thus ensuring a more coordinated motion of the shackle profiles with the tyre shoe.
The invention is based on the recognition that, by inserting a particular sliding subassembly between the shackle shank and the shackle profiles, the harmful consequences due to the flattening of tyre can be avoided by appropriate shortening the shackle shank and, as the case may be, by bending the shackle profiles and the shackle shank relative to each other, thus enabling the task to be solved.
According to the objective set, the shackle device for show-shackles mounted periodically on tyres of vehicles according to the invention - which includes a shackle shank and one or more shackle profiles connected to the shackle shank, having said shackle shank a contact surface borne at least partly on the shoe of the tyre while the shackle shank has a WO 98/14339 PCT/HiT9'7/00056 cogged part serving for the connection to the hub assembly provided with adjusting and fastening mechanism - is designed in a manner that a sliding subassembly that allows the shackle profile to displace towards the hub assembly is inserted between the shackle shank and the shackle profile.
A further criterion of the shackle device according to the invention may be that a spring bundle is fastened to the sliding subassembly at its outer end facing the shackle profile, while the spring bundle is connected either directly or by inserting a connecting plate to the shackle profile.
In an exemplary embodiment of the shackle de~lce, the shackle shank has one or more guide grooves machined in it and the sliding subassembly includes side plates in contact with the side faces of the shackle shank, at least one spacer inserted into the guide grooves of shackle shank and allowing a limited displacement, as well as fastening elements connecting the side plates with the spacers together.
In another embodiment of the invention, a restoring element e.g. a compression spring is arranged in at least one of the guide grooves of the shackle shank, and the restoring element is inserted between the shackle shank and the spacer.
In another embodiment of the shackle device, holes of diameter same as the diameter of rivets fastening the spring bundle together are at both ends of middle spring plate in the spring bundle that is fastened to the sliding subassembly movable on the shackle shank, and openings of diameter larger than the diameter of the rivets are arranged at one end of the outer spring plates each mounted on both sides of the middle spring plate within the spring bundle.
1n a further embodiment of the shackle device according to the invention, the contact surface of the shackle profile is completed with a shoe plate of size and form adapted to the tyre shoe and the shoe plate is provided with elements improving the clinging capability.
WO 98/14339 PCTIIiU97/00056 The shoe plate is mounted with grasping ribs suitable to improve the clinging capability and the grasping ribs are fastened to the shoe plate parallel to the shackle profile section borne on the tyre shoe.
In another design of the shackle deaice, exsections are formed on the shackle profile section in contact with the tyre shoe and-or on the grasping ribs mounted on the shoe plate.
The shoe plate and/or the grasping ribs are fastened by means of cone-head rivets to the shackle profile.
The advantage of the shackle dcvrce a~cordm~; to the invention is that, by using a structure allowing the shackles to be shortened and bent, the operation of self adjusting character of the shackle profiles that adapt rtself to the deformation of the tyre shoe can be significantly improved, thus also malnns: the c,p~rational features of the snow-shackle more favourable.
In the following, the mvrntron rs described in connection with an exemplary embodiment, based on drawnngs In the drawings Fig. 1 shows the front view of the snow-shackle provided with the shackle device according to the invention.

Figs. i and 2 show the snow-shackle design provided with the shackle device according to the invention. It is well shown that the flexible shackle device is composed of the 2 shackle shank connected to the 1 hub assembly, the 3 sliding subassembly, the 4 spring bundle, the 5 shackle profile and the 6 connecting plate that connects the 5 shackle profile to the 4 spring bundle. The spring bundle is fastened by means of the 10 rivets to the 3a outer end of the 3 sliding subassembly and to the 5 shackle profile. The 2 shackle shank is connected by means of its end provided with '_'c cogging to the 1 hub assembly, while the other end of the '_' shackle shank a connected to the 3 sliding subassembly.
The ?c cogging enables the position of ? shackle; shank to be modified by displacing it within the 1 hub assembly, thereby altering the protruding length of the shackle device, while the 3 sliding subassembly allows the distance between the '_' shackle shank and the 5 shackle profile to be shortened and restored to its original size automatically according to the deformation of the tyre.
The Fig. also shows the I 1 shoe plate mounted on the Sa contact surface of the 5 shackle profile as well as the 12 grasping ribs fastened to the 11 shoe plate that serve for improving the clinging capability. Similarly, the 13 exsections also serving for improving the clinging capability are arranged on both the Sb shoe surface of 5 shackle profile and the 12 grasping ribs in this embodiment, as shown in Fig. ?.
The clinging capability is also improved by the 14 cone-head rivets that fasten the 5 shackle profile and the 12 grasping ribs to the 11 shoe plate. It shall be noted here that the 14 cone-head rivets can also be used in themselves; or even, any other element improving the clinging capability by ensuring the better engagement of the 5 shackle profile with the snow-covered and icy road surface and the tyre shoe can also be used.
Figs. 3 and 4 shows the arrangement and connection of component parts of 3 sliding subassembly movable on the 3 shackle shank. 1t is shown that the 31 side plates in contact with the 2a side faces of 3 shackle shank and the 7 spacers are fastened together by means of the 9 fastening elements, thus forming the covered space in the 3 sliding subassembly in which the 2 shackle shank is inserted.
A further disadvantage of the fixed shackle design is that the part of shackles in contact with the tyre shoe will be unable to follow the declination of road surface from the horizontal plane and its roughness. In extreme cases, this disadvantage of the rigid shackle structure may lead to the permanent deformation of shackle shanks, or even, breaking of the hub assembly.

According to the objective set, the shackle device for show-shackles mounted periodically on tyres of vehicles according to the invention - which includes a shackle shank and one or more shackle profiles connected to the shackle shank, having said shackle shank a contact surface borne at least partly on the shoe of the tyre while the shackle shank has a WO 98/14339 PCT/HiT9'7/00056 cogged part serving for the connection to the hub assembly provided with adjusting and fastening mechanism - is designed in a manner that a sliding subassembly that allows the shackle profile to displace towards the hub assembly is inserted between the shackle shank and the shackle profile.
A further criterion of the shackle device according to the invention may be that a spring bundle is fastened to the sliding subassembly at its outer end facing the shackle profile, while the spring bundle is connected either directly or by inserting a connecting plate to the shackle profile.
In an exemplary embodiment of the shackle de~lce, the shackle shank has one or more guide grooves machined in it and the sliding subassembly includes side plates in contact with the side faces of the shackle shank, at least one spacer inserted into the guide grooves of shackle shank and allowing a limited displacement, as well as fastening elements connecting the side plates with the spacers together.
In another embodiment of the invention, a restoring element e.g. a compression spring is arranged in at least one of the guide grooves of the shackle shank, and the restoring element is inserted between the shackle shank and the spacer.
In another embodiment of the shackle device, holes of diameter same as the diameter of rivets fastening the spring bundle together are at both ends of middle spring plate in the spring bundle that is fastened to the sliding subassembly movable on the shackle shank, and openings of diameter larger than the diameter of the rivets are arranged at one end of the outer spring plates each mounted on both sides of the middle spring plate within the spring bundle.
1n a further embodiment of the shackle device according to the invention, the contact surface of the shackle profile is completed with a shoe plate of size and form adapted to the tyre shoe and the shoe plate is provided with elements improving the clinging capability.
WO 98/14339 PCTIIiU97/00056 The shoe plate is mounted with grasping ribs suitable to improve the clinging capability and the grasping ribs are fastened to the shoe plate parallel to the shackle profile section borne on the tyre shoe.
In another design of the shackle deaice, exsections are formed on the shackle profile section in contact with the tyre shoe and-or on the grasping ribs mounted on the shoe plate.
The shoe plate and/or the grasping ribs are fastened by means of cone-head rivets to the shackle profile.

Figs. i and 2 show the snow-shackle design provided with the shackle device according to the invention. It is well shown that the flexible shackle device is composed of the 2 shackle shank connected to the 1 hub assembly, the 3 sliding subassembly, the 4 spring bundle, the 5 shackle profile and the 6 connecting plate that connects the 5 shackle profile to the 4 spring bundle. The spring bundle is fastened by means of the 10 rivets to the 3a outer end of the 3 sliding subassembly and to the 5 shackle profile. The 2 shackle shank is connected by means of its end provided with '_'c cogging to the 1 hub assembly, while the other end of the '_' shackle shank a connected to the 3 sliding subassembly.
The ?c cogging enables the position of ? shackle; shank to be modified by displacing it within the 1 hub assembly, thereby altering the protruding length of the shackle device, while the 3 sliding subassembly allows the distance between the '_' shackle shank and the 5 shackle profile to be shortened and restored to its original size automatically according to the deformation of the tyre.
The Fig. also shows the I 1 shoe plate mounted on the Sa contact surface of the 5 shackle profile as well as the 12 grasping ribs fastened to the 11 shoe plate that serve for improving the clinging capability. Similarly, the 13 exsections also serving for improving the clinging capability are arranged on both the Sb shoe surface of 5 shackle profile and the 12 grasping ribs in this embodiment, as shown in Fig. ?.
The clinging capability is also improved by the 14 cone-head rivets that fasten the 5 shackle profile and the 12 grasping ribs to the 11 shoe plate. It shall be noted here that the 14 cone-head rivets can also be used in themselves; or even, any other element improving the clinging capability by ensuring the better engagement of the 5 shackle profile with the snow-covered and icy road surface and the tyre shoe can also be used.
Figs. 3 and 4 shows the arrangement and connection of component parts of 3 sliding subassembly movable on the 3 shackle shank. 1t is shown that the 31 side plates in contact with the 2a side faces of 3 shackle shank and the 7 spacers are fastened together by means of the 9 fastening elements, thus forming the covered space in the 3 sliding subassembly in which the 2 shackle shank is inserted.
The ? shackle shank is provided with the ?b guide grooves passing through between the 2a side faces. In the 2b guide grooves, the 8 restoring elements serving for resetting the 3 sliding subassembly to its outer end position - compression springs in this embodiment - are arranged, on the one hand, and the 7 spacers are also inserted and guided in the 2b guide grooves, on the other hand. It is also well shown that, in this embodiment, the 8 restoring elements are arranged between the ?b guide groove formed in the 2 shackle shank and the 7 spacer fastened to the 3 sliding subassembly, thus ensuring the 2 shackle shank and the 5 shackle profile to be stretched out.
Of course, the 5 shackle profile can be retained in its outer end position by means of 8 restoring elements arranged in a different manner; thus, the embodiment shown in the Figures is only one of the possible solutions without being considered to be exclusive Fig. 5 shows the arrangement of the 4 spring bundle composed of the 4a middle spring plate and the 4c outer spring plates surrounding it on both sides. It is shown that the size of 4b holes formed in the 4c outer spring plates - that are forced to slide if the 4 spring bundle is bent - at their 4 I c ends connected to the 31 side plates is the same as the diameter "D" of the 10 rivets, while the 4c outer spring plates at their 4?c ends fastened to the 6 connecting plates are provided with 4d openings of size larger than the diameter "D" of the 10 rivets, in order to allow the possibility of sliding.
However, the 4b holes at both ends - 41 a and 4?c - of the 4a middle spring plate are of diameter equal to the diameter "D" of the 10 rivets.
The shackle device according to the invention fulfills its function while performing complex movement within the snow-shackle fastened to the tyre.
Basically, the rest position of the 3 sliding subassembly, i.e. the maximum length of the shackle, is ensured by the reaction exerted by the tyre. The force exerted by the 8 restoring elements - also acting towards the end position that determines the maximum length of the shackle - is negligible as compared to the reaction exerted by the tyre.
_'7_ During the rotation of the wheel, the tyre rolls over the 5 shackle profiles borne on the road surface as well as the 11 shoe plate and its components. When the flattening tyre rolls over the 5 shackle profile, the 3 sliding subassembly slides along the 2a side faces of the 2 shackle to a distance determined by the extent of flattening, while the 1 hub assembly of the snow-shackle remains stable essentially at the centre. The method of operation described eliminates the unfavourable dynamic impacts and the irregular roaming motion of the 1 hub assembly to an unacceptable extent together with its harmful consequences described above, that would occur in the case of rigid shackle design.
During the use of the shackle device, the 5 spring bundle enables the 5 shackle profile borne on the road surface as well as the elements improving the clinging capability to be function in a self dependent manner.
The operation of the 4 spring bundle shows hysteresis, as a result of the friction due to the compression force of the 10 rivets. As a result of the hysteresis, the 5 shackle profile and the elements improving the clinging capability while resting on the tyre shoe "preserve" their setting according to the lateral angular offset of the road surface and, at the same time, they also stand any extreme deviations due to the roughness of the road surface without damage.
Thus, the use of the -t spring bundle eliminates the risks that occur in the case of snow-shackles provided with rigid shackles The shackle device accordinS to the invention is well suitable to be used under winter circumstances in order to improve the traffic safety of various vehicles using tyres.
