Abstract
The present invention is an elastic flat tread which can prevent an elastic solid from cracking even if the vehicle runs on a protruding object during traveling. For this purpose, the elastic flat tread is provided with any core (1, 11, 115) of a core (1, 11) attached to a link (6) and a core (115) attached to a metal plate (9A) which is attached to a link (8), and end portions (1a, 1b; 11a, 11h; 115a, 115b) in a longitudinal direction of the aforesaid any core (1, 11, 115) are bent toward the side not in contact with the ground.
Claims12
An elastic flat tread for a crawler having a traveling direction;
- the tread comprising:
- links arrayed in the traveling direction of the crawler and comprising link end portions;
- pins coupling the link end portions of adjacent links;
- and
- cores attached to respective ones of the links and covered with an elastic solid at least on a ground-facing side thereof;
- said cores comprising end portions that are bent, in a longitudinal direction, away from the ground-facing side thereof;
- and
- wherein at least one of said cores on a side opposite the ground is covered with an elastic solid including an outer surface of the elastic solid which extends along the opposite side parallel to said bent core end portions.
An elastic flat tread for a crawler having a traveling direction;
- the tread comprising:
- links arrayed in the traveling direction of the crawler and comprising link end portions;
- pins coupling the link end portions of adjacent links;
- and
- cores attached to respective ones of the links and covered with an elastic solid at least on a ground-facing side thereof;
- said cores comprising end portions that are bent, in a longitudinal direction, away from the ground-facing side thereof;
- and
- wherein the ratio between a height h, which is from a mounting surface for said link up to a tip end in a height direction of the end portion in the longitudinal direction of at least one of said cores, and a link pitch Lp is 0.05≦h/Lp≦0.25.
An elastic flat tread for a crawler having a traveling direction;
- the tread comprising:
- links arrayed in the traveling direction of the crawler and comprising link end portions;
- pins coupling the link end portions of adjacent links;
- and
- cores attached to respective ones of the links and covered with an elastic solid at least on a ground-facing side thereof;
- said cores comprising end portions that are bent, in a longitudinal direction, away from the ground-facing side thereof, and
- wherein the ratio between a height h, which is from a mounting surface for said link up to a tip end in a height direction of the end portion in the longitudinal direction of at least one of said cores, and a height H of the elastic flat tread is 0.08≦h/H≦0.50.
An elastic flat tread for a crawler having a traveling direction;
- the tread comprising:
- links arrayed in the traveling direction of the crawler and comprising link end portions;
- pins coupling the link end portions of adjacent links;
- and
- cores attached to respective ones of the links and covered with an elastic solid at least on a ground-facing side thereof,
- said cores comprising end portions that are bent, in a longitudinal direction, away from the ground-facing side thereof, and
- wherein the ratio between a width W1 of at least one of said cores and a width W2 of a tip end in the longitudinal direction of the one of said cores is 0.5≦W2/W1≦0.9.
An elastic flat tread for a crawler having a traveling direction;
- the tread comprising:
- links arrayed in the traveling direction of the crawler and comprising link end portions;
- pins coupling the link end portions of adjacent links;
- and
- cores attached to respective ones of the links and covered with an elastic solid at least on a ground-facing side thereof,
- said cores comprising end portions that are bent, in a longitudinal direction, away from the ground-facing side thereof;
- and
- wherein end portions of said elastic solid are protruded outward relative to the tip ends of the end portions in the longitudinal direction of said core;
- and
- wherein at least one of said cores, on a side opposite the ground, is covered with an elastic solid including an outer surface of the elastic solid which extends along the opposite side parallel to said bent core end portions.
