Abstract
An elastic crawler traveling apparatus having an elastic crawler in a shape of an endless belt, a sprocket for a crawler belt arranged to be brought into contact with an inner face of the elastic crawler, a driven wheel, and a rolling wheel, the elastic crawler including a belt main body, a plurality of projections formed to project at intervals along a peripheral direction on an inner face of the belt main body, and a tension member embedded at an inner portion of the belt main body for restricting elongation of the belt main body, in which the sprocket has a contact portion to contact the belt main body and a contact width of the contact portion in a belt width direction of the elastic crawler is wider than a root width of the projection in the belt width direction.
Claims9
An elastic crawler traveling apparatus, comprising:
- an elastic crawler in a shape of an endless belt formed of an elastic material,
- a sprocket for a crawler belt arranged to be brought into contact with an inner face of the elastic crawler,
- a driven wheel;
- and
- a rolling wheel,
- wherein the elastic crawler comprises a belt main body;
- a plurality of projections formed to project at intervals therebetween along a peripheral direction of the elastic crawler on the belt main body;
- and a tension member embedded in an inner portion of the belt main body for restricting elongation of the belt main body,
- wherein the sprocket for the crawler belt comprises a contact portion to contact the belt main body, the contact portion having a contact width which is substantially equal to an embedding width of the tension member in a belt width direction of the elastic crawler, a plurality of drive tooth portions to be engaged with the projections;
- and a barrel portion main body integrally formed with the drive tooth portions,
- wherein the barrel portion main body is formed with a recessed portion on a portion thereof between the drive tooth portions so as to prevent a projected end portion of the projection and the barrel portion main body from being brought into contact with each other.
