Definitions

  • the invention relates to transport engineering, and in particular to caterpillar engines with elastic tracks and can be used on vehicles, for example, tractors.
  • Known caterpillar propulsion vehicle containing the driving and steering wheels and covering them with an elastic track with a tread
  • the caterpillar is made in the form of a rubber tape with layers of flexible inextensible cord vulcanized in it.
  • On the inner side of the caterpillar is a longitudinal row of protrusions for engagement with a gear drive wheel.
  • the protrusions are made in conjunction with the rubber track array and are also reinforced with cord.
  • On both sides of a series of protrusions on the inner side of the track flat longitudinal tracks are made in contact with the track rollers and the guide wheel of the mover.
  • a disadvantage of the known caterpillar propulsion vehicle is that when the protrusions of the caterpillar interact with the drive wheel, high voltages occur at their base, resulting in reduced service life and reliability of the caterpillar tracks.
  • a disadvantage of the known caterpillar propulsion vehicle is that the magnitude of the frictional forces between the smooth surfaces of the drive wheel and the track does not provide high power transmission from the wheel to the track, and to increase the friction forces an increase in the tension of the track is required, which increases the load in the tensioner. Disclosure of invention
  • the basis of the invention is the task to create such a caterpillar propulsion vehicle, in which a new form of execution of the outer surfaces of the supporting drive and guide wheels, as well as the inner surface of the covering their tracks, would increase the friction forces between the contacting surfaces of the drive wheel and the track, and also improve the fixation of the track on the wheels from lateral displacement, which would increase the power transmitted from the drive wheel to the track and increase the reliability of the track drive.
  • the problem is solved in that in the caterpillar propulsion vehicle, containing the supporting drive and guide wheels and covering them with an elastic track with a tread, according to the invention, on the outer surface of the wheels, mostly elastic, ring protrusions are made between their ends, and on the inner surface of the track, predominantly rubber cord, - longitudinal protrusions entering into the grooves between the annular protrusions of the wheels and in contact with them by their side surfaces, the protrusions on the wheels x and on the caterpillar are wedge-shaped.
  • annular protrusions are made, between which grooves are formed, which include longitudinal protrusions made on the inner surface of the track. Traction from the drive wheel to the track is transmitted due to friction between the side surfaces of the annular protrusions of the wheels and the longitudinal protrusions of the track. Due to the wedge-shaped shape of the annular and longitudinal protrusions, the force that presses the side surfaces of the annular and longitudinal protrusions against each other increases the friction force between the contacting surfaces of the drive wheel and the track increases, which allows to transmit higher traction from the wheel to the track.
  • the annular protrusions serve as stops, preventing the transverse movement of the longitudinal protrusions, and, therefore, improving the fixation of the track on the wheels from moving in the transverse direction.
  • the caterpillar is more securely held on wheels when it is subjected to lateral forces, for example, when the vehicle is turned, or when it moves across the slope. All of the above indicates the presence of a causal relationship between the totality of the essential features of the invention and the achieved technical result.

  • figure 5 is a General view of the mover in the perspective 3/4 in front
  • Fig.6 is a General view of the propulsion in the 3/4 view from the rear.
  • FIG. 1-6 An embodiment of the proposed caterpillar propulsion vehicle is illustrated in figures 1-6, where it is indicated: 1 - the drive wheel, 2 - the guide wheel, 3 - elastic track, 4 - flexible inextensible cord, 5 - tread, 6,7 - the ends of the drive wheel, 8.9 - ends of the steering wheel, 10.11 - annular protrusions, 12 - longitudinal protrusions, 13, 14, 15 - grooves.
  • the caterpillar propulsion device of the vehicle comprises, predominantly elastic, the drive wheel 1, the guide wheel 2 and the elastic track 3 covering the said wheels, mainly rubber cord.
  • the caterpillar 3 is made in the form of an endless rubber band with a layer of flexible inextensible cord 4 vulcanized in its array, made mainly of synthetic cord yarns.
  • a protector 5 is made on the outer surface of the track 3.
  • annular protrusions 10 and 11 are made on their outer surface, having a wedge shape, and longitudinal protrusions on the inner surface of the track 3 12, also wedge-shaped.
  • the longitudinal protrusions 12 enter the grooves 13 between the annular protrusions 10 of the driving wheel 1 and the grooves 14 between the annular protrusions 11 of the guide wheel 2 and are in contact with these protrusions with their side surfaces.
  • the track is tensioned using a tension mechanism (not shown in the drawings).
  • the proposed caterpillar mover can be used on various land vehicles, but its most effective use is on traction machines, such as all-wheel drive tractors, all-terrain vehicles, off-road vehicles, snowmobiles.
  • Caterpillar propulsion vehicle operates as follows. Since the caterpillar 3 is in a taut position, the lateral surfaces of the longitudinal protrusions 12 of the caterpillar are tightly pressed against the lateral surfaces of the annular protrusions 10 and 11, respectively, of the driving and steering wheels 1 and 2.
  • the driving wheel 1 rotates, due to the frictional forces between the contacting the surfaces of the annular protrusions 10 and the longitudinal protrusions 12, the power supplied from the engine is transmitted from the drive wheel 1 to the caterpillar 3, which is rewound on wheels 1 and 2 and ensures the movement of the vehicle.
  • a transverse force acts on the track 3 through the tread 5.
  • the annular protrusions 10 and 11 of the driving 1 and guide 2 wheels hold the longitudinal protrusions 12 from lateral displacement and thus prevent the track 3 from falling off the drive and guide wheels.
  • the pressing force of their side surfaces to each other significantly exceeds the clamping force of the track compared to the smooth cylindrical surface of the drive wheel in the known caterpillar mover.
  • the frictional force between the contacting surfaces of the wheel and the track increases, which allows higher traction forces to be transmitted from the wheel to the track.
  • the execution on the outer surfaces of the driving and guide wheels of the annular protrusions improves the fixation of the track on the wheels from lateral movement. Due to this, the caterpillar is more reliably held on wheels when turning the vehicle, when lateral forces act on it. This improves the reliability of the caterpillar mover.

Abstract

Le propulseur à chenilles de l'invention peut s'utiliser dans des véhicules de transport, de préférence à traction tels que les tracteurs. Le propulseur à chenilles pour véhicule de transport comprend des roues d'appui, dont une roue d'entraînement et des roues de direction. Ces roues sont de préférence élastiques et sont entourées d'une chenille élastique possédant de préférence une corde caoutchoutée et une bande de roulement. A la surface externe des roues, entre leurs extrémités, on a réalisé des saillies annulaires, et à la surface interne de la chenille on a réalisé des saillies longitudinales. Les saillies longitudinales rentrent dans les cannelures entre les saillies annulaires des roues et sont en contact avec ces dernières par leurs surfaces latérales. Les saillies sur les roues et sur la chenille sont en forme de coin. L'invention permet ainsi d'augmenter la force de frottement entre les surfaces de contact de la roue d'entraînement et de la chenille et d'améliorer l'adhérence de la chenille aux roues de manière à les prémunir contre tout déboîtement transversal.
