Problems solved by technology

[0004] However, in the technology disclosed in the above-mentioned Utility Model Registration No. 2595443 and the technology disclosed in the Utility Model Registration No. 260785, fastening members such as bolts are welded to a core frame (core bar) made of sheet metal. Therefore, sufficient rigidity cannot be ensured, and problems such as bolt loosening and falling off are likely to occur due to bending, twisting, etc.
On the other hand, in the technology disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 10-16835, the installation strength can be improved by using the mounting bracket to connect the track shoes, but the thickness of the elastic body that bears the load cannot be thickened, and damage to the elastic body occurs. Strain concentration makes it difficult to ensure durability

Embodiment Construction

[0035] Next, specific embodiments of the elastomer track shoe of the present invention will be described with reference to the drawings.

[0036] exist figure 1 In , a front view (a), a bottom view (b) and a side view (c) of the elastic body track shoe according to the first embodiment of the present invention are shown.

[0037] The elastic track shoe 1 of this embodiment is installed on the ground contact surface side of the iron track shoe 3 by a plurality of (four in this embodiment) bolts 4, and the iron track shoe 3 is There are four) bolts 2 and nuts (not shown in the figure) to be installed on the track link not shown in the figure.

[0038] The track shoe 3 has three gripping plates 5, 6, 7 in the central part and two side parts along the length direction of the tread. In addition, in the track shoe 3, a bolt insertion hole 8 for inserting the bolt 2 for mounting the track shoe 3 on the track link is provided at the central part, and at the same time, at positions n...

Abstract

An elastic track shoe, comprising a mandrel integrally formed by casting, forging, or cutting, wherein the ground-contact surface side of the mandrel is covered with an elastic body, and the shape of the portion of the mandrel on which the ground-contact surface of the elastic body is projected is formed such that the mandrel is divided into two parts, whereby, by using the rigid mandrel, the occurrence of looseness of bolts can be avoided, and the thickness of the elastic body receiving a load can be increased irrespective of a grouser.

Description

technical field [0001] The present invention relates to an elastic body shoe (protective shoe) attached to the ground contact surface side of an iron shoe plate of a track-type vehicle. Background technique [0002] Conventionally, as a crawler belt of a chain-rail vehicle such as a bulldozer or a hydraulic excavator, a crawler belt having an iron track shoe structure with a grouser formed on the contact surface side is endlessly connected by a plurality of links. However, when such crawlers run on asphalt roads, the road surface is markedly damaged, so protective crawlers (elastomer crawlers) made of elastic bodies such as rubber are attached to the contact surface side of the iron crawler shoes. [0003] As an example of the conventional technology of this elastic body track shoe, there exists the technology disclosed by utility model registration No. 2595443. The elastic body track shoes described in this gazette are formed by forming a metal plate into a corrugated shap...
