Problems solved by technology

For this reason, when the tracked vehicle is turning left and right, the elastic body track shoes are difficult to slide, so it is not easy to operate, and it cannot turn smoothly, thus destroying the comfort of riding
At the same time, due to the large friction coefficient, the wear of the flat part 13a of the elastic body 13 is large, and there is a problem of shortening the service life of the elastic body track shoe

Embodiment Construction

[0021] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0022] figure 1 , is a side view of the elastic body track shoe of Embodiment 1. exist figure 1 Among them, an elastomer track shoe 1 has a core bone 2 and an elastic body 3 such as rubber vulcanized around the core bone 2 . A concave portion 5 is provided on the ground contact surface side of the central portion of the elastic body 3 in the track width direction (left-right direction in the figure). In the concave portion 5, there is a hole that penetrates the elastic body 3 and the core bar 2 from the ground contact surface to the non-ground contact surface. Left and right mounting holes 4, 4. The central portion of the core bar 2 on the side of the non-grounding surface is in a state exposed from the elastic body 3, and the exposed surface of each core bar 2 becomes a bolt (not shown) inserted into the left and right mounting holes 4, 4. , is mounted on the mou...

Abstract

The invention provides an elastic body track shoe installed on an annular chain link (11). The ground contact surface of the elastic body (3) forms a When grounding, the side surfaces of both wing ends are higher than the side ends of the recessed part (5), and the inclined grounding surface (3a) is inclined relative to the installation surface (2a) of the chain link. The inclined grounding surfaces (3b, 3d) may also be curved surfaces. It is preferable to make the surrounding of the inclined grounding surface (3c) an inner curved surface or an outer curved surface. Therefore, the vehicle can be turned smoothly on a hard and flat road surface, and has the advantage of long service life.

Description

technical field [0001] The invention relates to elastic body track shoes which can be installed on chain links or iron track shoes. Background technique [0002] In the past, in order to reduce the noise of tracked vehicles when they are running, for the purpose of improving ride comfort and protecting the road surface (preventing damage), elastic crawlers with lateral patterns made of elastic bodies such as rubber are often used on the ground contact parts. In this kind of elastic track, there is a rubber pad formed by vulcanizing and bonding elastic bodies such as rubber on the side of the metal core that is in contact with the ground, and is installed on a plurality of iron chain links connected in a ring with bolts. Rubber pad type track shoes. [0003] As the prior art of the rubber pad type, for example, as disclosed in Japanese Patent Application Laid-Open No. 7-152305, Figure 6 It is a side view of the elastic track shoe described in this gazette. exist Figure 6 ...
