Description

Technical Field

[0001] This utility model relates to the field of rubber track technology, and in particular to a shock-absorbing excavator track. Background Technology

[0002] Excavator rubber tracks are a type of highly elastic, high-strength synthetic rubber product widely used in various excavators and other large machinery. Compared to traditional steel tracks, excavator rubber tracks offer significant advantages. They not only boast better environmental performance but also provide superior traction and stability in complex terrain. Furthermore, rubber tracks cause less wear on the ground, protecting the surface while improving the excavator's working efficiency.

[0003] Traditional excavator tracks often have improperly designed tread patterns, resulting in poor shock resistance. During operation, this can accelerate the wear of components such as track rollers and drive wheels, reducing the equipment's lifespan. Furthermore, greater caution is required during operation to avoid safety issues caused by swaying, thereby reducing travel speed and work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a shock-absorbing excavator track to solve the defects of improper tread pattern design in existing shock-absorbing excavator tracks.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a shock-absorbing excavator track, comprising a track and an inner rubber layer disposed therein; an outer rubber layer is disposed on the outside of the track, and the surface of the outer rubber layer is coated with a reinforcing layer; a transmission rib is disposed between the inner rubber layer and the reinforcing layer, and a steel cord is disposed between the transmission rib and the outer rubber layer; the outer rubber layer includes a pattern, longitudinal grooves and transverse grooves; the pattern is disposed on both sides of the surface of the outer rubber layer, and longitudinal grooves are disposed between the patterns; the transverse grooves are disposed at the middle position of the surface of the outer rubber layer.

[0006] Preferably, the pattern is similar to the shape of a mechanical wrench, and the pattern and longitudinal grooves are arranged alternately with respect to the surface of the outer rubber layer.

[0007] Preferably, the transverse grooves are evenly spaced about the surface of the outer rubber layer.

[0008] Preferably, the reinforcing layer includes a water-resistant layer, a corrosion-resistant layer, and a wear-resistant layer. The wear-resistant layer is coated on the surface of the outer rubber layer, and the material of the wear-resistant layer is a ceramic wear-resistant coating.

[0009] Preferably, the surface of the wear-resistant layer is coated with a corrosion-resistant layer, and the material of the corrosion-resistant layer is a phenolic resin wear-resistant coating.

[0010] Preferably, the surface of the corrosion-resistant layer is coated with a water-resistant layer, and the water-resistant layer is made of acrylic resin wear-resistant coating.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the shock-absorbing excavator track, when the equipment is in use, improves the shock resistance and traction of the excavator track through the wrench-shaped pattern set on its surface, and the track surface is coated with a reinforcing layer, so that the track can be used for a long time in various environments, extending its service life.

[0012] 1. By setting patterns, the outer rubber layer has patterns on both sides, and the patterns are similar to the shape of a mechanical wrench. The wrench-shaped design can increase the contact area and friction between the rubber track and the ground, thereby improving the excavator's shock resistance, driving stability and traction. At the same time, it can better embed into loose media such as soil and sand, providing stronger grip.

[0013] 2. By incorporating a reinforcing layer, the outer rubber layer is sequentially coated with a wear-resistant layer, a corrosion-resistant layer, and a water-resistant layer. The water-resistant layer has excellent weather resistance and water resistance, making the track suitable for operation in humid environments. The corrosion-resistant layer makes the track suitable for operation in corrosive environments. The wear-resistant layer has extremely high hardness and wear resistance, making the track suitable for withstanding high-load fine particle erosion and wear, thereby extending the service life of the excavator track.
