Definitions

  • the present invention relates to a monolithic flexible track aimed at being used for converting a wheeled vehicle into a tracked vehicle.
  • monolithic is used herein as opposed to a track composed of a plurality of connected rigid elements extending in cross direction of the length of the track, the rigid elements being embedded in a rubber phase or not.
  • a vast number of solutions have been proposed for converting a wheeled vehicle into a tracked vehicle, according to which a monolithic flexible track is installed around a pair of wheels remote from each other on the same side of a vehicle, at least one of the wheels being a driven wheel.
  • the track is usually reinforced in longitudinal direction, for example by one or more steel or textile fibres or cords.
  • a flexible endless track which is made of an elastomeric material reinforced with nylon or steel filamentary material in the form of a continuous cord wound across the width of the track in a plurality of side-by-side turns.
  • this track is an endless, continuous one, the tires of the wheels need to be deflated when mounting the track thereto. This operation is complicated and time consuming.
  • the complementary operation of removing the track from the wheels presents the same disadvantages.
  • U.S. Pat. No. 4,362,340 Another solution for adapting a wheeled truck having the tires arranged in sets of two adjacent tires, to agricultural purposes and to make it suitable for travelling with heavy loads on weak soil has been proposed by U.S. Pat. No. 4,362,340.
  • an endless tread type track is mounted around a pair of consecutive tires, the track being made of a flexible material, for example synthetic resin or rubber-like material, if so desired containing one or more canvas or nylon liners.
  • the track is built up of a single part, both ends of which are interconnected when mounted to a vehicle to form-an endless belt.
  • the track may however also be built up of two or more parts, which are connected to each other by two or more joints.
  • DE-U-9302375.8 a flexible belt for use as a track is disclosed, which solves the problem of minimising the risk to elongation following use, as this adversely affects the contact between the track and its driving.
  • the flexible belt disclosed in DE-U-9302375.8 is provided to be used as such, there is no teaching to use this belt in combination with a wheeled vehicle.
  • the belt disclosed in DE-U-9302375.8 comprises a plurality of parallel bands connected to each other in cross direction of the track, each band being internally reinforced by a plurality of metal cords.
  • the coupling of parallel bands in cross direction of the truck is achieved by means of a plurality of U-shaped profiles, each U-profile being received in corresponding recesses in the parallel bands.
  • Each band has an opposite first and second end part.
  • Each end part contains a central coupling hole for coupling the first end part to the second end part in longitudinal direction of the track, a reinforcing cord extending as a loop around the coupling hole
  • a flexible track which comprises a band of flexible material provided for mounting around at least two successive vehicle wheels, taken in the movement direction of the vehicle.
  • the band of this invention has a first and a second end part which extend in cross direction of the band and comprise mutually co-operating connecting means for connecting the first end part to the second end part with the aim of forming an endless track.
  • the flexible track of the present invention is characterised by the presence of a plurality of guiding wings spaced apart from each other and disposed along opposite longitudinal sides of the band. The guiding wings protrude from the inner surface of the band facing the wheels so as to form a channel which is aimed at engaging opposite lateral sides of at least part of the vehicle wheels.
  • the presence of the guiding wings along the sides of the track counteracts de-tracking of the track from the wheels when the track is driven in extreme conditions.
  • the inventor has namely observed that when loaded, the wheels expand in lateral direction, as a consequence of which the sides of the wheels contact the guiding wings and are forced against the guiding wings.
  • the friction forces in width direction of the belt arising from such contact ensure an improved grip of the track to the wheels and a consequently reduced risk to slipping.
  • the reduced risk to slipping has been observed even in case little or no circumferential stress is exerted by the track, where the track showed some sagging, as well as in severe circumstances with heavy grounds.
  • the positive driving of the track by the sides of the wheels reduces the sensitivity of the driving to wearing of the running surface of the tires and has the effect that the need to circumferential tension for driving the track may be dispensed with.
  • the optimised contact surface between the wheels and the track contributes to this effect.
  • the guiding wings are arranged to exert a clamping force on the opposite lateral sides of the vehicle wheels. Furthermore, it is preferred that the guiding wings show some resilience, as this renders the use of the track less dependent from the width of the wheels.
  • each guiding wing is preferably reinforced with a rigid core.
  • the rigid core may for example be made of steel or any other suitable material.
  • the rigid core is preferably composed of two substantially perpendicular disposed portions, a first transversally extending portion, the other portions extending substantially perpendicular thereto in the guiding wing. The presence of the rigid core counteracts flexion of the guiding wings in width direction of the track, thus increasing friction forces between the wheels and the guiding wings as the wheels expand when loaded.
  • the inner side of at least part of the guiding wings faces the wheels and is provided with profiles protruding from the inner side towards the wheels in order to improve the grip to the wheels and to minimise the risk to building of frictional heat.
  • At least part of the outer side of the guiding wings is provided with profiles protruding from the outer side in order to improve grip of the band to the ground.
  • the guiding wings can be made of the same flexible material as the, material of which the track is made, or of a different material. Preferably however there are made of the same material.
  • a further improvement of the transmission efficiency of the displacement of the wheels to the track is achieved if the inner face of the band aimed at contacting the wheels, is provided with traction ribs.
  • the traction ribs are disposed so as to allow engagement of corresponding recesses present in the vehicle wheels, especially in case unwanted slipping of the wheels on the track occurs.
  • the circumferential tension exerted by the track to the wheels can be reduced, which is beneficial to the transmission of the power of the engine on the ground through the tracked wheels, even in case of sagging of the track.
  • a plurality of protrusions may be provided on the inner side of the track.
  • the number, shape and pattern in which the protrusions are arranged will be adapted by the person skilled in the art to achieve optimum engagement of the wheels.
  • the track may flex at the position where the first and second end part are connected to each other.
  • the first and second end part of the band are hingingly connectable to each other.
  • At least one flexible elongated reinforcing element is embedded in the band. This at least one reinforcing element extends along the length of the said band and forms a loop around the hole or holes provided at the position of each of the first and second end part of the band.
  • each reinforcing element comprises a first and a second end part, each of the end parts being secured to the reinforcing element to form a loop.
  • the presence of the loop provides an additional reinforcement of the end parts of the track.
  • the presence of the loops has the effect that the tension forces endured at the connection of the two end parts of the track in operation of the track, will be absorbed by the flexible elongated reinforcing element. In that way the risk to the formation of cracks in the elastomeric band at the sides of the passage receiving the connecting means for the two end parts, may be minimised.
  • the band comprises opposed first and second lateral longitudinal sides and each reinforcing element extends continuously from one longitudinal side of the said band to the opposite longitudinal side of the band in making alternate loops around each hole of each of the first and second end parts of the band.
  • This configuration provides the track with an homogeneous traction resistance, especially at its end parts, since each passage for receiving connecting means for connecting the end parts of the track, will be properly reinforced.
  • the shape of the reinforcing element is not critical to the invention and will be adapted by the person skilled in the art depending on the intended use. It may however be preferred to use a reinforcing element comprising at least one metal or textile cord or strip, as these materials show a high tension resistance and a high flexibility. More preferably, the reinforcing element is composed of a steel cord strip embedded in an elastomeric material coating; or a plurality of adjacent steel cords embedded in the elastomeric material coating.
  • the first and second end parts of the band are provided with alternating extensions and recesses, each extension being provided with at least one hole.
  • Each extension of the first end part is provided to engage a corresponding recess of the second end part
  • each extension of the second end part is provided to engage a corresponding recess of the first end part.
  • a channel of successive holes is formed for receiving the connecting means for connecting the first and second end parts of the band.
  • the size of the connecting means is preferably selected such that it corresponds to the formula:
  • F breaking breaking load of longitudinal reinforcing element ( 7 ) i.e. steel cord, textile, fiber, . . . ( 16 )
  • ⁇ 0.2 tensile strength of the connecting means ( 13 )
  • the track of this invention is a non continuous one, which is composed of flexible material reinforced with a liner of nylon, canvas or the like, embedded in the track.
  • the non-continuity with the connectable opposite end parts enables an easy mounting of the track to the vehicle wheels, for example by driving the vehicle on top of an open, depleted track, i.e. a track with the end parts not connected, until the tyres are positioned at inside of the tracks, followed by fastening the end parts together around the wheels.
  • the means for connecting the first and second extremities of the band comprise at least one rigid or flexible elongated member having a length corresponding to the width of the band and having a cross section adapted for passing through each hole of the first and second end part of the track. This enables a fast and easy connection of the said extremities.
  • each of the holes is provided with a rigid tubing section. This ensures that passage for receiving the means for maintaining connected the extremities of the band conserves its shape even when the said extremities are submitted to high tension forces.
  • Either only one or both end parts of the track may further be provided with a rigid bush, for example a moulded rigid bush, the rigid bushes of the first and second end part being made so as to engage each other.
  • the rigid bushes can be moulded in an elastomer and may for example be formed by alternating rectangular extensions and cavities.
  • each moulded extension comprises a hole for receiving a tubing section.
  • the tubing sections form a substantially uninterrupted channel for receiving a rod, for example a steel rod, aimed at connecting and fastening the first and second end parts of the track in view of forming an endless belt around the vehicle wheels.
  • the track further comprises additional rigid or flexible reinforcing elements disposed across its length.
  • additional rigid or flexible reinforcing elements disposed across its length. This provides the band with an improved transverse stability, reduced risk to wearing and improved resistance to impact damages. This is important when the vehicle on which the track according to the invention is mounted has to progress in heavy and highly irregular ground conditions and a uniform distribution of the pressure exerted to the ground is aimed at.
  • the flexible track according to the invention further comprises at least one intermediary piece being removably connectable at the said first and second extremities of the band in view of modifying the length of the track. This enables the said track to be adapted to nearly any configuration of wheeled vehicles.

  • the track further preferably comprises a single or a plurality of flexible reinforcing elements 11 extending from a first longitudinal side of the band to a second longitudinal side of the band 5 .
  • This reinforcing element provides a protection shield against puncture and damage from outside bodies and implies the desired longitudinal stiffening to the track.
