Definitions

  • the present invention relates to tracks for all-terrain vehicles equipped with wheels with tyres or similar.
  • Such vehicles are, for example, forestry forwarders and harvesters.
  • the invention can be applied to rubber tyres or a solution with other similar wheels.
  • Forestry machines are generally equipped with wide rubber tyres. In some conditions, tracks are required to improve traction and climbing ability. Tracks reduce the surface pressure, thus also reducing damage to the ground of the forest. Special tracks are designed for wet and marshy conditions, as well as for snow and ice. Such a track must produce good flotation and good cleaning properties with the aid of snow and mud removal. Because tracks designed to improve traction may become clogged and jam in marshy or snowy conditions, they are not suitable for terrain where good flotation is required. On the other hand, tracks producing good flotation generally do not have good traction. Each machine must therefore have two sets of tracks, if the device is used in varying conditions and terrain, as is generally the case. An investment in two sets of tracks is naturally a great financial burden.
  • the tracks of off-road vehicles equipped with rubber tyres comprise a track plate, which is oriented over the width of the tyre, and in which there are guide plates at each end.
  • the guide plates are oriented over the edge and to the sides of the tyre, in such a way that the tyre remains between them.
  • This construction is typical of tracks designed for rubber tyres, as guide plates are required to hold the tracks on the tyres. For this reason rubber-tyre tracks differ from those used, for example, in excavators.
  • At the ends of the track plates there are also lugs, which point at right-angles over the length of the track plates.
  • a track assembly is created for an all-terrain vehicle equipped with wheels.
  • the track assembly comprises at least two track plates, each of which has a body that is dimensioned to extend over the width of the tyre, and which has guide plates that point away from the body in such a way that they can be arranged to extend over the edge of, and to the sides of the tyre, at each end of which track plate there are lugs, which are oriented transversely to the length of the track plate on each side of the track plate, in each of which lug there is a hole for a link, which joints the track plates together to form an entire track.
  • At least one link comprising a link body, which has length, and the link body of which comprises, at least at one end, two lugs and a slot between them, and in the lugs there are holes for pins, and a groove, parallel to the holes and transverse to the pins and the length of the link body, in the portion of the link body between the lugs, on at least one side of the link body.
  • the pins are welded to the link body.
  • the pins are attached to the link body by nuts.
  • the link body comprises tow side plates, which are joined together by pins.
  • the link body is a single piece.
  • FIGURE 1 shows a tyre set, which is equipped with a first track assembly according to at least any of the embodiments of the present invention
  • FIGURE 2 shows a tyre set, which is equipped with a second track assembly according to at least some of the embodiments of the present invention
  • FIGURE 3 shows a partly exploded view of the track assembly according to at least some of the embodiments of the present invention
  • FIGURE 4 shows the track assembly of Figure 3 from another angle
  • FIGURE 5 shows a link used in at least some embodiments of the invention
  • FIGURE 6 shows a side view of the link of Figure 5;
  • FIGURE 7 shows an end view of the link of Figure 5; and [0019] FIGURE 8 show a second view of the link of Figure 5.
  • track assembly comprises complete entire tracks and portions of such tracks.
  • the longitudinal direction of a track assembly is the direction of the centre line of the longitudinal direction of the track.
  • the transverse direction of the track assembly is at right angles to the longitudinal direction and the same as the direction of the longitudinal direction of the track plates.
  • Forestry machines are generally equipped with wide rubber tyres. In some conditions, tracks are required to improve traction and climbing ability. Different types of tracks are required in different terrain conditions.
  • One characteristic of the present invention is to produces a track assembly, which can be adapted to different terrain conditions simply by attaching accessories to a basic track. These components can be designed to produce better flotation in marshy or snowy conditions, or better traction when required, or a combination of these properties.
  • Additional plates can be also be shaped in such a way that they prepare the ground. This property is suitable, for example, for land improvement and preparation work. The additional plates can be shaped in such way that they automatically prepare the ground as they drive over it.
  • a second characteristic of the invention is the use of links and locking pins to make a crawler track. By locking the rotation of the pins, wear can be concentrated in easily replaced components. The maintenance and repair of the track assembly will then be cost-effective and quick, when compared to previous methods.
  • FIGURE 1 shows a set of tyres, which is equipped with a track assembly according to at least some of the embodiments of the present invention.
  • the track assembly 2 comprises track plates 3, which are at right angles to the longitudinal direction of the track assembly 2.
  • the track plates 3 are intended to provide good traction on the ground or whatever surface the vehicle is moving on.
  • the track plates 3 are generally made from steel and different manufacturers have their own definitions for the shape of the plate.
  • the length of the track plate 3 is set in such a way that it is oriented across the width of the tyre and thus depends of the dimensions of the tyres.
  • the guide plates 4 are intended to keep the track assembly 2 on the tyres 1. Because the tyres 1 do not have guide surfaces or grooves, as is the case in the wheels used in a bulldozer, the track assembly fitting the tyres must be guided from the edges of the tyres 1, so that they hold the track assembly 2 on the tyres, even on difficult terrain.
  • Track assemblies implemented according to various embodiments of the invention can be applied to different applications, in which there are wheels that require guiding the track from the edges of the wheel or tyre.
  • Such tyre and wheel arrangements are in, for example, in agricultural machines and tractors, or in mining machines, or in work machines in peat excavation, as well as in car tyres as a new snow chain, or in quad bikes.
  • a set of wheels or tyres there may be only a single wheel, around which the track rotates, or instead in the set there can be three or more wheels instead of two.
  • the number of wheels or tyres is limited mainly by the limited steering of a long set of wheels and a long track.
  • agricultural machines there are generally four wheels, or individual wheels are used.
  • the wheels can be of different sizes and they can be two or even more next to each other as in a twin-wheel solution.
  • FIGURES 2 and 3 show the same track as FIGURE 1, but equipped with infill plates 5.
  • the infill plates 5 are fitted between two parallel track plates 3.
  • the infill plates 5 are used in all the gaps between two parallel track plates 3, but it can be envisaged that a smaller number of infill plates is used and some gaps remain empty. In this way, traction and surface pressure can be adjusted when necessary or when desired.
  • the track assembly of an all-terrain vehicle equipped with tyres 1 comprises at least two track plates 3, in each of which is a body 6, which is dimensioned to extend over the width of the tyre 1.
  • the body 6 is curved in such a way that it follows the profile of the tyre 1 and produces an extension in the direction transverse to the direction of rotation of the wheel.
  • the transverse direction and detailed shape of the body 6 can vary according to the manufacturer’s design principles.
  • guide plates 4 which point away from the body 6 in such a way that they can be set to extend over the edge of the tyre 1 and to the sides of the tyres 1.
  • the guide plates 4 are flat plates, which extend at an obtuse angle from the extreme ends of the body 6, in such a way that the body 6 and guide plates 4 form an open U-shape, into which the tyre 1 fits.
  • the shape of the guide plates 4 can vary.
  • the body 6 comprises lugs 7 at each end of the track plate 3, which are oriented transversely to the track plate 3.
  • the lugs 7 are set on each side of the body 6 of the track plate 3, in such a way that the lugs 7 are on opposite sides of the ends of the body 6.
  • the lugs 7 are oriented to extend in the longitudinal direction of the track assembly.
  • In each lug 7 there is at least one hole for a link 11, which joints the track plates 3 together to form one entire track assembly.
  • the link 11 there is a link body 12, which has length and at least one link hole 13 in each opposite end of the link body 12.
  • the track assembly 2 is formed by joining the track plates 3 together with the aid of the links 11 and pins 14.
  • the pins 14 are set to run through a pair formed by a hole 13 in the body 12 of the link and at least one hole in the lug 7 in the track plate 3, in order to form the crawler track.
  • the pins 14 are locked relative to the hole 13 in the link 11, so that the rotation of the pins 14 in the hole 13 is prevented.
  • the locking of the pins 14 can be implemented simply by welding the pins to the link body 12. Alternatively, locking can be implemented by using locking grooves and keys, or other shapes that prevent the pin 14 from rotating in the hole 13.
  • the pins 14 can also be attached using nuts, closure pins, or other method of attachment known in machine construction. Alternatively, the pins 14 can be freely rotating and it can be envisaged that they are equipped with sleeve bearings in the manner of roller chains.
