The invention relates to a novel rubber track structure, which is characterized in that a steel cord is not used as a strong layer, an internal framework with longitudinal strength and transverse rigidity is arranged, and the internal framework is wrapped by a rubber layer, so that better connection strength can be obtained.

Description

Novel rubber track structure

Technical Field

The invention relates to a novel rubber crawler belt structure.

Background

In order to obtain a better driving effect, a crawler-type transmission structure is often adopted in small and medium-sized engineering machinery such as an excavator, and an iron chain type steel crawler structure is often adopted in a traditional crawler-type transmission mode.

With the maturity of rubber technology, the rubber track can also be suitable for the use of small and medium-sized engineering machinery, and in order to ensure the strength of rubber, steel cords are often adopted as a strength layer, and then a rubber track structure meeting the strength requirement is prepared in a way of vulcanized rubber wrapping.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a novel rubber track structure.

A novel rubber track structure comprises a plurality of hinges which are connected end to end, and adjacent hinges are connected through pin shafts; the surfaces of the pin shafts are all wrapped by rubber layers;

the hinge comprises a head inner clamping part and a tail outer clamping part, the head inner clamping part is provided with a connecting pipe, and the middle part of the connecting pipe is provided with a pin hole matched with the pin shaft; the outer width of the head inner clamping part is matched with the groove width of the tail outer clamping part;

the hinge pin sequentially penetrates through two adjacent hinges, the middle of the hinge pin is inserted in the connecting pipe, and two ends of the hinge pin extend outwards.

Preferably, a chain structure matched with the chain wheel is formed between the hinges which are connected end to end.

Preferably, the extending end of the pin shaft is flat, and the size of the cross section of the extending end is gradually reduced from inside to outside.

Preferably, the bottom of the rubber layer is provided with an anti-skid pattern.

Preferably, the rubber layer is wrapped on the outer surface of the pin shaft through vulcanization.

Preferably, the hinge is made of cast steel.

Has the advantages that:

the invention relates to a novel rubber track structure, which is characterized in that a steel cord is not used as a strong layer, an internal framework with longitudinal strength and transverse rigidity is arranged, and the internal framework is wrapped by a rubber layer, so that better connection strength can be obtained.

Except that the chain track is in pin connection with the pin shaft and can rotate, the chain track is mutually restricted front and back, left and right, has small transverse and longitudinal deformation, prevents driving wheels, guide wheels and derailment of equipment, and operates stably.

When in specific use, a plurality of sections of rubber track sections can be manufactured and then assembled into an annular rubber track section by section, and one or more sections of the annular rubber track section can be replaced in the use process; or be vulcanized into an integral annular rubber track in sections.

Detailed Description

For the purpose of enhancing the understanding of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.

As shown in fig. 1-6, a novel rubber track structure comprises a plurality of hinges 1 connected end to end, and adjacent hinges 1 are connected through a pin shaft 2; the surfaces of the pin shafts 2 are all wrapped by rubber layers;

the hinge 1 comprises a head inner clamping part and a tail outer clamping part, wherein a connecting pipe is arranged at the head inner clamping part, and a pin hole matched with the pin shaft is formed in the middle of the connecting pipe; the outer width of the head inner clamping part is matched with the groove width of the tail outer clamping part;

the pin shaft 2 sequentially penetrates through two adjacent hinges, the middle part of the pin shaft 2 is inserted in the connecting pipe, and two ends of the pin shaft 2 extend outwards.

Chain structures matched with the chain wheels are formed among the hinges 1 which are connected end to end.

The extension end of the pin shaft 2 is flat, and the size of the cross section of the extension end is gradually reduced from inside to outside.

During the use, with 1 end to end of a plurality of hinge, insert round pin axle 2 between two adjacent hinges 1 and make multistage rubber track, multistage rubber track subdivision equipment becomes annular rubber track, the drive wheel of cooperation equipment, guide wheel etc. are used together, rubber track is rotatable except that pin connection is rotatable with round pin axle 2, all restrict each other all around, horizontal longitudinal deformation is very little, prevent the drive wheel of equipment, the guide wheel derails, the surface of round pin axle 2 all extends outwards through rubber layer parcel and both ends, this kind of structure makes equipment operate steadily. Each section of rubber track all is standardized design, makes things convenient for the maintenance and the change in later stage, has prolonged rubber track's life, has reduced use cost.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
